The Role of Medical Technology in the Rising Costs of Insurance Premiums and Healthcare in America

Technological discovery, innovation, and advancement continue to profoundly impact theinnovation-scorecard-landing-page American patient and the economics of American healthcare.  History teaches us that the overall cost of healthcare increases proportionally with the climbing costs of medical technology and the increased training, marketing, and regulatory processes it routinely postulates.  According to The Henry J. Kaiser Family Foundation (2007), “medical technology can be used to refer to the procedures, equipment, and processes by which medical care is delivered.”  This broad spectrum yields an inevitable linkage to virtually every form of medical diagnostic, testing, and procedure.  It can therefore be reasonably inferred that medical technology plays a critical role in the overall cost of healthcare and, consequently, the price of insurance premiums.

Recent data depicts a magnanimous increase in per capita health care spending which rose from $356 in 1970 to $6,697 in 2005, with an expected projection of $12,320 in 2015 (Kaiser, 2007).  With changes of this magnitude, some contend that new medical technological discoveries may be attributed to “about one-half or more of real long-term spending growth” (Kaiser, 2007).  Consequently, the Medicare program “is projected to go bankrupt in nine years”, and overall health care cost is expected to increase from its present $2.1 trillion annually to $4 trillion in 10 years” (Callahan, 2008).  As the reigning pioneer of medical innovation and products development, it is it is imperative that the United States deliver the best technology to its patients without compromising quality or access to care.  Only then can the benefits in public health, the economy, and job productivity be realized.

CT-ScanThe prodigious impact of medical technology necessitates an examination of three major catalysts: CT imaging, drugs for heart disease, and hip replacements for their contributions to healthcare spending and its impact on the overall quality of life for American patients.  The overutilization of diagnostic technologies is highly contributory to excessive healthcare spending.  A versatile component of comprehensive medical treatment, they fulfill screening and assessment needs for a multitude of traumatic injuries and diseases across large populations.  The long term cost benefits of screening for asymptomatic, low-risk individuals comes at an initial high cost.  While early detection is an integral part of preventative medicine, overly aggressive screening practices by clinicians can overburden the patient and the healthcare system.  These financial implications are compounded by the increased sensitivity and decreased specificity of new diagnostic technologies that lead to further diagnostic testing (Mohr et. al., 2001).

According to Mohr et. al, spending can be reduced in the short term when the use of diagnostic technologies are “restricted to an appropriately selected population” (2001).  Their use amongst moderate to high risk individuals would be conducive to responsible screening and healthcare spending.

Beta-BlockersRecent advances in heart disease have played major roles in the treatment and prevention of America’s deadliest disease and for heart attack, the leading cause of death (Kaiser 2007).  This certainly did not come without a monumental growth in cost.  According to Cutler and McClellan, “the average Medicare spending per heart attack patient increased by $9,600, from $12,100 in 1984 to $21,700 in 1998” (Federal Reserve Bank of San Francisco FRBSF, 2002).  The 1990s were a historically significant period due to the advent of clot-inhibiting pharmaceuticals, angioplasty for revascularization, and stents to open blood vessels (Kaiser 2007).  The 2000s introduced diagnostic advances to further prevent the prevalence of myocardial infarction as well as new pharmaceutical treatments for its management.

ACE inhibitors, beta-blockers, and statins were employed for the long-term treatment of heart attack victims and for high-risk patients (Kaiser, 2007).  Rehabilitative cardiac programs also became more preventative in nature while defibrillators became increasingly accessible in public places and more utilized in patients with abnormal heart rhythms (Kaiser, 2007).

These advances proved to be effective as “the overall mortality rate from heart attacks felluntitled by almost half, from 345.2 to 186.0 per 100,000 persons from 1980-2000” (Kaiser, 2007).  While the US has higher rates of bypass and angioplasty procedures when compared to other countries, the difference in mortality rates amongst heart attack patients is considerably less (FRBSF, 2002).  This can be attributed to possible incentives awarded to hospitals and physicians by traditional private insurance companies to provide open bypass units (FRBSF, 2002).  This practice would not be possible in the managed health care systems offered in other countries.  An increase in considerably less expensive, non-invasive, preventative approaches is therefore necessary to improve the overall quality, productivity, and expectancy of life of heart attack patients.  Attempts to counteract the detrimental effects of excessive healthcare spending in America can commence by reducing the delivery of unnecessary treatments, surgical procedures, and care.

The growing demand for hip replacement procedures is an additional economic burden toWMT_BFH both Medicare and the American healthcare system.  According to the American Academy of Orthopaedic Surgeons, there are nearly 200,000 hip replacements completed in the U.S. each year with a total surgery cost ranging between $8,474 to $20,874 with a mean of $14,510 (Dolan & Robinson, 2010).  It is projected that this demand will more than double by 2030 which can be attributed to the epidemic of obesity, an aging population, and patients who desire to increase the quality and productivity of their lives (Dolan & Robinson, 2010).  A new market equilibrium will then be achieved with increases in both the market price of implants and the demand.  The hospital would ultimately need to increase its supply to satisfy market demands impacted by a growth in population and an increase in the number of the elderly.        

The high cost of hip implantation devices is due in part to individual clinician preferences and lack of regard for economic savvy and excessive healthcare spending.  A limited use of multiple manufacturers dictates a market characterized by hiHip-articleLargegh demands with low competitiveness.  According to Dolan & Robinson, the cost of one hip implantation at 45 surveyed California hospitals ranged from $3,645 to $11,308, with an average of $6,531 (2010).  This is a prime example of the occurrence of market monopolization and the lack of competitiveness amongst vendors securing hospital contracts.  In the event the surgical staff is forced to switch to an alternate manufacturer, additional labor and administrative costs will apply (Dolan & Robinson, 2010).  Also, the fixed amounts (DRGs) paid to hospitals by Medicare simply cannot keep up with the rising costs of implantation devices as they comprise a large portion of insurance reimbursement.  A reduction in hospital reimbursements will cause significant implications on the hospital including potential detrimental revenue loss.  The hospital will need to charge more for services rendered and aggressively negotiate commercial payments with health insurance plans.  The overall reduction in hip implantation devices and procedures therefore necessitates a coordinated effort between institutions, surgical staff, and vendors so as to increase the numbers of manufacturers, market competitiveness and ultimately decrease the cost of implantation devices.

imagesCATT76ITA key consideration in the overall cost of medical devices is the federal government’s regulatory standards and complex approval process.  Industry executives and investors are now concerned that increased FDA involvement is compromising the American economy and the potential for developing new innovation (Pollack, 2011).  According to a report by PricewaterhouseCoopers, the US reigns as the world leader in medical device innovation and is home to “some 32 of the 46 medical technology companies with annual sales exceeding $1 billion” (Pollack, 2011).  This lead is expected to decline due to the increased preference for the European market which offers a more rapid approval process.  The process by which products can enter the market in the U.S. has become increasingly time-consuming, exorbitantly expensive, and risky.  “Some estimates put the total cost of developing a novel drug at more than $800 million” (McClellan, 2003).  In Europe, a device must be declared safe before distribution.  Approval in the US is more stringent; however, as a device must be proven to be both safe and effective for the treatment of a disease or condition through multiple clinical trials.  The approval process is handled by a third party in Europe while the US requires the involvement of a central agency such as the FDA.

Although the FDA has recently agreed to employ a more “consistent” and predictable review process,” safety will not be compromised (Pollack 2011).  Dr. Jeffrey Shuren, the director of the FDA’s medical device division affirms the responsibility to exert caution by stating, “We don’t use our people as guinea pigs in the US” (Pollack, 2011).  As devices become more advanced, the FDA must maintain its duty to safeguard the American people without depriving the best technology available.  It must also prevent the outsourcing of jobs to European countries and the decline of the economy.  According to the Lewin Group, “the medical industry employed 422,778 workers nationwide, paid $24.6 billion in earnings, and shipped $135.9 billion worth of products” (Pollack, 2011).  Accordingly, the medical device industry plays a critical role in supporting the infrastructure of the American economy and those employed within it.  It is imperative that the FDA find an appropriate balance between ensuring safety and job security to achieve the most favorable health and economical outcomes.

Improvement in healthcare spending is perhaps best exemplified by the utilization of ehrelectronic health records.  This medical technology contributes to practice organization and efficiency made possible with the storage and electronic delivery of health information.  It also facilitates doctor-patient communication by increasing patient awareness and maintaining comprehensive, organized medical histories.  The Geisinger Model for Healthcare for Medicare and Medicaid beneficiaries advocates the cost-effectiveness and versatility of this assistive technology.  Its use allows non-Geisinger physicians and their staff to have the ability to access their electronic health records through a portal that allows electronic communication between Geisinger specialists and sub-specialists.  This integrated system is an effective prophylaxis for unnecessary hospital visits and the prevention of illness and disease (Davis, 2010).  Electronic records will promote coordinated care amongst multiple providers, drive down administrative costs, and ultimately reduce mortality across broad populations.  Additionally, the minimization of paper usage will prevent the loss or damage of the record, reduce administrative costs, and conserve the Earth’s natural resources.  As in the use of any technology, the short term expenses will initially be elevated for the practice or large institution; however, the long term benefits in conservation and efficiency will far exceed the initial investment.

health-care-costs-300x199The impact of medical technology on the recent exuberance of healthcare spending cannot be evaluated as a whole, but rather must be examined on case by case basis.  Excessive spending is generally dependent on several factors.  Technologies used in conjunction with subsequent forms of treatment are a major cause, especially when it requires the use of additional health care services such as extended hospital stays and/or physician office visits (Kaiser, 2007). A second factor is the particular technology’s frequency of use and the size of the population it covers.  If the diagnostic does not facilitate methods of treatment, the burden of unnecessary testing and spending emerges.  New innovations in diagnostics can prevent overutilization by promoting more targeted treatments (Kaiser, 2007).  This can foster a more rapid rate of healing and prevent clinical complications.  The capacity for preventative care to extend life expectancy, and improve the quality of life is difficult to place a price tag on.  The true value of medical technology is best perceived by the individual impacted by it.

imagesCABU8Q6FThe fragmentation of private and public healthcare in America poses the continuing challenge of controlling costs and averting inordinate expenditures that result from the increased emphasis on highly specialized procedures and care.  The economical impact is exacerbated by the uninsured that accumulate devastating medical debts through the repetitive utilization of hospitals and diagnostics when receiving emergent care.  Any limit placed on the delivery of medical technology would be unprecedented as medical technology plays such a definitive role in American medicine.  Still, there is much debate and uncertainty over determining a possible solution.  According to Callahan (2008), “40% of Americans believe that medical technology can always save their lives.” A similar reverence for technology is less prevalent in Europe where managed care is more effective in controlling excessive healthcare expenditures.

A possible, promising solution is the introduction of Accountable Care Organizations.   The untitledphysician-led system would places a strict emphasis on evidence-based care and the application of comparative effectiveness research to determine the efficacy of drugs, technology, and procedures.  This would result in a reduction in premiums, increasing affordability and the accountability of care.  Incentives for ACO providers aimed towards avoiding unnecessary tests and procedures require collaborated efforts for achieving illness prevention and medical cost reduction.  A potential downside to ACOs; however, is the potential for monopolistic activity amongst insurers due to potential hospital mergers and provider consolidation.  While the downsides of ACOs are worthy of ample consideration by both the consumer and economist, the potential positive implications of ACOs are monumental steps in the right direction.

medtechMonolithic advancements in the areas of cancer and heart disease, proteomics, nanotechnology, and information technology have been made in America.  In the dawn of healthcare reform; however, attempts must now be made to increase the efficient use of medical technology by both doctors and patients, reduce the outrageous costs and ambivalence of developing new technology, and eliminate device and procedure cost disparities across geographical regions.  By trimming unnecessary, unproductive treatments, championing preventative medicine and the acquisition of more primary care physicians, the affordability of healthcare can be more attainable for all Americans.

GET SCREENED TO BE INJURY-FREE: The Rise of Functional Movement Screening and Corrective Exercise

Acute and chronic injuries attributed to participation in sports, recreation, and exercise (SRE) are major contributors to the public health burden in America today.  According to The Centers for Disease Control and Preventioworld-s-worst-football-sports-injuries-soccer-injury-evern’s (CDC) National Center for Injury Prevention, more than 10,000 people are treated in emergency departments (ED) for injuries sustained in SRE activities every day (2006).  In fact, “at least one of every five ED visits for an injury results from participation in sports or recreation.”  The CDC (2006) also estimates that 715,000 sports and recreation injuries occur annually in school settings alone.

The susceptibility of children and femchild-sports-injury-doctor348wy050410ale athletes is a special concern.  The prevention of chronic injuries attributed to repetitive microtrauma in children is critical as “biomechanical and clinical evidence suggests that growth cartilage, especially that of the articular surface, is less resistant to repetitive microinjury” when compared to adults (Micheli & Klein, 1991).  An estimated 2,200 anterior cruciate ligament (ACL) ruptures occur annually in female collegiate athletes in both the recreational and competitive ranks resulting in treatment and rehabilitation costs of about $17,000 per ACL injury (Owen, et. al, 2006). This of course does not consider the loss of long term participation, loss of a scholarship, and future disability from arthritic changes in a reconstructed knee (Owen, et. al, 2006).

The impact of unintended SRE-induced injuries on the prevalence of physicalobesity inactivity is paramount as it exacerbates the epidemic of obesity in America.  According to data from the National Health and Nutrition Examination Survey, 2009–2010, more than one-third of adults (35.7%) and approximately 12.5 million (17%) of children and adolescents aged 2 to19 years of age are obese in the United States (CDC, 2012).  The main goal in performing pre-participation or performance screenings is to decrease the prevalence of these injuries, enhance performance, and ultimately improve the quality of life (Cook, et.al).  Filipa, et. al (2006) advocate the implementation of a neuromuscular training program (NMTP) that focuses on core stability exercises to prevent lower extremity injury, especially in female athletes who have deficits in trunk proprioception and neuromuscular control.

Anatomical malignment and muscle-tendon imbalances increase the risk for injury by contributing to joint problems and deficiencies in muscular strength, flexibility, and range of motion.  Poor core stability and decreased muscular synergy of the trunk and hip stabilizers have been thwomen playing soccereorized to inhibit optimal performance in power activities and to increase the susceptibility for injuries secondary to lack of control of the center of mass, especially in female athletes (Filipa, et. al, 2010).  Age is also an important risk factor for chronic orthopedic injuries such as rotator cuff tears.  “Approximately 40% of asymptomatic patients over 50 years of age have full-thickness rotator cuff tears and the prevalence of partial-and full-thickness tears in symptomatic patients over 60 years old is greater than 60%” (Moosikasuwan, et. al, 2005).  Repetitive micro-trauma, subacromial impingement, tendon degeneration, and hypovascularity, are theorized to be responsible for most tears and account for this age-dependent prevalence (Moosikasuwan, 2005).

When it comes to the goal of keeping athletes and active populations free of unintended patfempatellarapprehension1-4orthopedic injuries, the old adage: “a pound of prevention is worth an ounce of cure” holds true.  The traditional sports medicine model, pre-participation, and rehabilitation examinations rely on isolated, objective testing for joints and muscles along with skill performance assessments do not provide an adequate amount of baseline information (Cook, et.al, 2006).  These systematic methods are inferior as they neglect to assess common fundamental movement patterns that are essential to everyday movement and participation in exercise among active populations.  The use of a pre-participation screening to include the assessment of fundamental movements and muscular function; however,  is essential for designing safe, effective fitness programs that prevent injury and improve the efficiency of muscular movement to enhance overall wellness and performance.

Over the past 20 years, the profession of sports rehabilitation has experienced a paradigm shift, trending away from traditional, isolated assessment and strengthening and moving towards integrated, functional approaches, incorporating the principles of proprioceptive neuromuscular fascilitation (PNF), muscle synergy, and motor learning (Cook, Burton & Hoogenboom, 2006).  Advances in functional movement assessment developed by the leading physical therapist, Gray Cook, quantify an individual’s risk for injury and preparedness for activity through their Functional Movement Screen (FMS).  The FMS utilizes a ranking and grading system to detect functional limitations and asymmetries (FMS, 2012).  The FMS generates the Functional Movement Screen Score which serves as a baseline for targeting problems and tracking progress (FMS, 2012). The system also facilitates the implementation of corrective exercise and functional training programs that improve movement patterns, physical conditioning, and optimal performance.  Cook has introduced his FMS regimens to the U.S. Navy SEALS and the NFL (Tierney, 2011).  In addition, an estimated 8 out of 10 NFL teams, including the Atlanta Falcons, apply FMS to pinpoint muscular asymmetries and to develop appropriate functional training programs (Tierney, 2011).  In an American culture that embraces participation in sports, recreation, and exercise (SRE), functional movement assessments like the FMS are critical to detect deficits in mobility and balance that increase the susceptibility for injury and hinder performance.

With origins in rehabilitative exercise, the concept of functional training and its equipment has evolved as a means for correcting muscle and joint imbalances and impaired movement patterns.  Functional training targets the neuromuscular system using a progressive and individualized program of primarily weight bearing, multijoint and multiplanar exercises to improve dynamic and static balance, coordination, and proprioception (Beckham & Harper, 2010).  Functional training involves the integration of the nervous system by engaging the muscles that produce joint movement and stabilize the spine, hip, and scapulae (Beckham & Harper, 2010). This strengthens the kinetic chain and the transfer of energy and force from one joint to another in support of efficient movement (Beckham & Harper, 2010).  While traditional resistance training methods that rely on machines or free weights are more capable of providing large amounts of constant or variable resistance, they often limit range of motion and require less stabilization and balance when compared to functional training (Beckham & Harper, 2010).  A functional assessment completed prior to designing any functional training programs detects movement deficiencies, determines appropriate exercises, and provides a baseline for measuring progress.

trx-suspension-training-brisbaneThe emergence of several exciting functional training equipment innovations such as the TRX Suspension Trainer and Dynamic Variable Resistance Training have facilitated the diffusion of functional training by physical therapists, chiropractors, allied health professionals, fitness experts, and the public, resulting in a revolution of the fitness industry.  The TRX Suspension Trainer builds total body stability and strength by leveraging the user’s weight through hundreds of functional exercises.  The first proto-type was developed by Randy Hetrick, a former US Navy SEAL and special operations squadron commander who needed a way to keep his command and himself fit while deployed in South East Asia.  Without access to fitness facilities, Hetrick stitched together some parachute webbing to make straps and attached them to an anchor point.  Using his first prototype for the TRX Suspension Trainer, Hetrick developed the first TRX routines using his own body weight for resistance.  Fifty variations and 10 years later, the portable straps have grossed over $20 million in sales since they first hit the market in 2005 and have led to the emergence of further innovations in functional training equipment (Hu, 2009).

While the concept of functional training is not new, innovations such as the TRX are revolutionizing the fitness industry for its versatility and applicability to a B002YIA6SM-1wide variety of active populations including older adults.  The research of Whitehurst and colleagues (2005) reported significant improvements in agility, balance, and flexibility after functional training in addition to self-reported ratings of physical functioning and fewer doctors’ visits.  Fitness and rehabilitative exercise programs utilizing functional training and equipment can be implemented for anyone, regardless of age or fitness ability because the level of difficulty is determined by body positioning, speed, range of motion, duration of the exercise, and number of repetitions.  This style of training is compatible with any demographic from individuals rehabilitating from injuries to elite athletes preparing for competition.

As an FMS certified fitness professional, I advocate the habitual use of functional movement screening and advanced functional training regimens as part of an integrative approach to achieving health and wellness.  The reinforcement of proper functional movement patterns and advanced training helps individuals achieve the maximum benefits of regular functional exercise including improved fitness, weight management, and injury prevention.  Functional screening and training are sustainable modalities that will continue to be an integral part of fitness programming now and for years to come.

FAILING TO PLAN IS PLANNING TO FAIL: Prudent Disaster Management Ensures the Best Possible Outcomes

While the treachery of Hurricane Sandy still lingers, the destruction and devastation inflicted by the superstorm serves as a  poignant reminder of Mother Nature’s divine powers.  Through the harsh lessons of past natural disasters and emergency situations, modern disaster management has evolved.  In time, we have learned that preparedness and mitigation yield the best possible outcomes.

THE FOUR PHASES OF DISASTER MANAGEMENT

The four-phased approach of disaster management includes mitigation, preparedness, response, and recovery.  These require the collaborative participation of the following individuals/organizations: local first responders, the governments of the affected countries and additional countries, international organizations and financial institutions, regional organizations and associations, non-profit organizations, private organizations, and local and regional donors (Butcher, 2011).  With the increased prevalence of disasters occurring all throughout the world, we have witnessed a paradigm shift that aggrandizes the importance of preparedness and evidence-based mitigation prior to response and recovery.  The UN, international disaster management organizations, agencies, and interest groups now place an increased emphasis on prevention, especially in developing countries (Butcher, 2011).

PREPAREDNESS

The history of complex humanitarian agencies repeatedly teaches us that prudent disaster preparedness and mitigation strategies ensure the best possible outcomes.  The management of complex humanitarian emergencies is most efficacious when it has been preceded by a comprehensive physical risk assessment.  This contributes to the identification of elevated risks as well as the particular country or geographic area’s vulnerabilities to hazards.  This information can also be used to implement a plan for the procurement, organization, management, and coordination of all necessary personnel and relevant stakeholders.  This will ultimately ensure that the efforts of emergency management personnel, organizations, and citizens provide opportunities for the adequate preparation and mitigation of all forms of complex humanitarian emergencies and natural and man-made disasters.

MITIGATION

Due to a compromised authority, the presence of civil conflict, the fragmentation of the economic system and the decline in food security, emergency preparedness and risk protection is essential for the maintenance of critical economic assets and community resources during a complex humanitarian emergency.  Mitigation practices can be achieved through the assistance of national and international response communities to minimize adverse effects of the disaster and limit further loss of human life.  Effective mitigation strategies can be as simple as boarding up the windows of vulnerable infrastructures, placing sandbags around critical areas to prevent flooding, and maintaining water storage tanks in anticipation of possible water shortages.  By using effective management strategies for the preparedness, mitigation, response, and recovery of complex humanitarian emergencies, risks can be eliminated or reduced over the long term.

RESPONSE

Even superior planning, preparedness, and mitigation programs cannot prevent all disasters from occurring.  Response actions must therefore be put into place “prior to, during, and immediately after the hazard event occurs” (Butcher, 2011).  The treatment of hazards requires immediate action in the form of search and rescue, first aide, and evacuation.  Provisions for the procurement of food, water, and reliable infrastructure are necessary in addition to health and medical aide, disease surveillance, sanitation infrastructure, and security of humanitarian personnel and victims.  Critical infrastructure resumption, emergency social services, and donations management are essential components for long-term disaster management (Butcher, 2011).

 

RECOVERY

Lasting up to a year, recovery is also a long-term process as it contributes to the rehabilitation and repair of the physical and mental health of victims, necessary infrastructure, and social and economic systems (Butcher, 2011).  The complexity and urgency of recovery requires the skills of a variety of emergency management professionals and the application of extensive resources and equipment.  This serves as justification for increased global attention and required collaboration among individuals and families, communities, and even countries to recover lost assets and plan for the future.

DISASTER ASSESSMENT

In the early phases of a disaster, assessment activities provide the authorities the critical information to set disaster response and recovery objectives and policies for emergency assistance.  Emergency and humanitarian responders must be cognizant of the magnitude of the disaster, the location(s) impacted, and any disparities between the amount of resources required and those available.  Data collection by the authorities must therefore commence as soon as hazard risks are realized to enhance the capabilities for response and recovery, to minimize the disaster’s growth in intensity, and to reduce the overall number of lives lost, injuries sustained, property damage and loss, and environmental degradation (Butcher, 2011).  Accurate assessment information assists policy-makers who are tasked with prioritizing population needs and determining the most beneficial uses of existing resources.  Assessments monitor the progress of recovery, identifying crucial areas in need of more advanced analysis and further intervention.

Rapid land assessments should be completed as soon as possible by qualified experts working in collaboration with the IASC Country Team under the coordination of the UN Humanitarian Coordinator or Resident Coordinator so as to secure humanitarian funding and UN flash appeals, which require formulation “within five to seven days of declaration of an emergency disaster” (UN-HABITAT , 2010).  Led by the relevant government agency or department, land needs assessments utilize quantitative and qualitative data collection techniques to determine needs related to safe and secure access to land for shelter and livelihoods, particularly for the displaced populace (UN-HABITAT, 2010).  This information is critical to early recovery planning and mobilization of available resources.

A damage and loss assessment is necessary to estimate the total loss of life and the extent of physical damages to land, infrastructure, personal property, and important documents.  Data obtained through ministry assessments, relief and recovery agencies on the ground, satellite imagery, aerial photography, and pre-disaster surveys can help formulate a cost projection for the relief and recovery projects required (UN-HABITAT, 2010).  Surveys for land availability facilitate the identification of suitable locations for emergency shelter and medical aide along with the amount of corresponding staff, medical supplies, equipment, and security needed to support relief operations.  According to the International Federation of Red Cross and Red Crescent Societies (2000), on-site visual inspections combined with interviews can help obtain factual information that can be cross-checked with other sources and minimize potential for bias.  Continuous assessments are critical for determining the changing needs of victims and providing guidance to the affected country’s government, UN humanitarian agencies, NGOs, and other humanitarian organizations delivering assistance.

RISK COMMUNICATION

The honest communication of risk is critical to the public’s welfare as the delivery of information is essential for making informed decisions following the initial impact of a natural disaster.  A symbiotic relationship must exist between the public, policymakers, and the media that accommodates a timely and accurate risk assessment, the release of pertinent information, ongoing disaster surveillance, and trust.  “Citizens have a right to know the worst-case scenario and to participate in their own protection” (Butcher, 2011).  A satisfactory level of awareness and comprehension will promote a sense of trust between the public and authorities to minimize violence, injury, and death and promote collaboration and cooperation between victims and governmental and humanitarian agencies.

STRATEGIES TO MEET THE MEDICAL NEEDS OF DISPLACED POPULATIONS

Populations that are displaced following a catastrophic disaster or complex emergency have a broad range of medical and public health needs including, but not limited to, access to the following: medical care for the treatment of acute and chronic conditions, shelter, security, hygiene facilities, safe food and drinking water, and psychological care.  The victims of Hurricane Katrina faced “unprecedented death, injury, destruction, and population displacement” following “the deadliest U.S. hurricane since 1928 and likely the costliest natural disaster on record in the United States” (CDC, n.d.).  The excessive rainfall, mass flooding, and extreme winds caused by Hurricane Katrina heavily exposed its victims to traumatic injury and infectious disease, the two leading causes of death due to a disaster (Reilly, 2008).  Traumas attributed to automobile crashes, drowning, and carbon monoxide poisoning were worsened by the loss of access to healthcare (Lister, 2005).   Flooding compromised the quality of the water supply and the integrity of sewage disposal, increasing susceptibility for waterborne illness, while power line damage and power outages increased the risk for foodborne illness and electrocution (Lister, 2005).  Conditions for dehydration and heat stress were exacerbated by poor ventilation and lack of access to a potable water supply (Lister, 2005).

An effective prophylactic strategy for controlling the spread of infectious disease following a disaster is the administration of vaccinations to victims and emergency responders.  In the aftermath of Hurricane Katrina, the CDC facilitated the immunization of evacuees, emergency responders, and relief workers to reduce risks of tetanus from wounds and contraction of influenza, measles, chickenpox, and hepatitis A due to crowded conditions where some children may not have had current immunizations (Lister, 2005).  Due to the severity of illness associated with Vibrio infections, the CDC alerted health officials and other authorities to cases of Vibrioinfection amongst Hurricane Katrina victims (Lister, 2005).  The threat of infectious disease necessitated diarrheal illness surveillance to enable epidemiologic assessments for determining incidence rates and identifying potential epidemic levels of disease.

The treatment of acute and chronic conditions for displaced populations can be hampered due to a lack of access to healthcare facilities, the absence of medical records, displaced clinicians, and language barriers.  The aftermath of disasters can be characterized by the manifestation or exacerbation of symptoms of chronic illnesses and pre-existing conditions which are more prevalent in lower socioeconomic populations where access to healthcare is less common (Reilly, 2008).  Hurricane Katrina victims were in need of dialysis treatments, oxygen, and medication to treat asthma, hypertension, diabetes, COPD and other chronic diseases (Reilly, 2008).  The death of loved ones, the destruction and loss of homes and property, forced evacuation, separation from family, migration to unfamiliar places, and incidents of violence also necessitated short and long term psychological care.

A strategy for the reinforcement of medical response teams to conduct triage can facilitate the prioritization of medical care delivery.  The shelter at the George R. Brown Convention Center in Houston, TX was staffed with doctors, nurses, ER Physicians, critical care specialists, and paramedics from the nearby University of Texas Health Sciences Center who delivered care to Hurricane Katrina victims based on their acuity (Reilly, 2008). To supplement staff needs, the Texas State Department of health issued temporary licenses by reciprocity to out of state clinicians (Reilly, 2008).  This helped minimize the shortage of medical providers at the San Antonio shelter and other temporary facilities areas that provided medical care.

RESPONDING TO INTERNATIONAL DISASTERS

Launched in 1997, the SPHERE Project was developed to establish global minimum standards for serving the rights of disaster-affected people and to improve the effectiveness and accountability of humanitarian response.  A revolutionary initiative, the SPHERE Project is a collaborative effort by which humanitarian NGOs, the Red Cross, and the Crescent movement framed the Humanitarian Charter which defines the rights that individuals have in disaster situations.  Based on “the principles and provisions of international humanitarian law, international human rights law, refugee law and the Code of Conduct for the International Red Cross and Red Crescent Movement and Non-Governmental Organizations in Disaster Relief,”the Charter reaffirms the primary responsibility for states and governments to safeguard and assist their constituents in accordance with international legal obligations (SPHERE, 2004).  It also reasserts the right of disaster-affected populations to life with dignity, identifies the distinction between combatants and noncombatants, and honors the principles of non-refoulment (SPHERE, 1999).  Authorities are also strongly encouraged to allow for the protection and assistance of humanitarian organizations in the event that they are unwilling and/or unable to fulfill their responsibilities (SPHERE, 2004).

The SPHERE project established Minimum Standards and key indicators in six areas including water supply and sanitation, nutrition, food aid, food security, shelter, and health services.  The Minimum Standards serve as benchmarks for intervention planning while key indicators determine whether the standard has been met.  Most of the standards and the key indicators are ever-evolving as they are the work of over 400 organizations in 80 countries all around the world (SPHERE, 2004).  Their continuous refinement is a constant focus that requires the commitment and contributions of governments, NGOs, humanitarian agencies and the disaster response community worldwide.

The World Health Organization (WHO) is a specialized public health agency and a core member of the UN Disaster Management Team (UNDMT).  In the occurrence of an international emergency, the WHO, along with other agencies within the UN system, are called upon to provide urgent technical assistance, advice, support, and materials to assist disaster-affected countries and respond to the medical health needs of victims (Ockwell, 2003).  The WHO is a member of the Inter-Agency Standing Committee (IASC) and works in cooperation with the UN Resident Coordinator (UNRC), the Office for the Coordination of Humanitarian Affairs (OCHA), governments, local authorities, and other humanitarian organizations to plan, implement, and monitor emergency, rehabilitation, and recovery programs (Ockwell, 2003).  The WHO also provides financial support to facilitate the delivery of aide to victims of man-made and natural disasters.

The WHO is a proponent for the safety, protection, and respect of health personnel, infrastructure, and noncombatants (Ockwell, 2003).  The organization is responsible for the implementation of effective treatment and rehabilitation programs for victims of violence along with the systematic management of delayed health effects of mental and physical injuries (Ockwell, 2003).  The WHO may also provide essential supplies, equipment, training, services, and logistic-related support to address serious and immediate threats to public health in the absence of adequate assistance (Ockwell, 2003).  The WHO may also conduct joint inter-agency needs-assessment missions, organized in consultation with the government, and issue consolidated appeals in the name of the UN Secretary-General (Ockwell, 2003).

PUBLIC HEALTH CHALLENGES POSED BY TERRORISM

The broad spectrum of terrorist activities necessitates the application of a variety of public health disciplines.  The utilization of explosives, incendiaries, small arms and forms of chemical, biological, and radiological weapons on a population requires trenchant preparedness and response strategies at the local, state and federal levels.  Accordingly, the global impacts of terrorism have catalyzed training efforts by the military and civilian sectors as well as the establishment of effective medical countermeasures for the potential use of bacteria, viruses, and toxins as biological weapons.  In consideration of the multitude of offensive biological weapons programs by at least twenty-five nations around the world, the threat for global biological warfare is serious and the possibility for devastating casualties remains high (Calhoun, 1996).

Due to the ever-evolving mechanisms for biological, chemical, and radiologic acts of terrorism, the continuous development and appropriate application of medical countermeasures are required to minimize casualties and the overall public health impact.  Preparedness strategies are essential to protect the integrity and efficiency of local and perhaps national public health infrastructure and the food and water supplies.  Large-scale attacks involving the variola virus (smallpox), aerosolized anthrax spores, a nerve gas, or food borne biological or chemical agent could task local emergency medical services and hospitals with an unprecedented deluge of patients, both infected and “worried well,” seeking immediate medical attention.  The critical need for emergency transportation vehicles, medical supplies, diagnostic tests, hospital beds, health care providers, and public health personnel could overwhelm the public health system and corresponding infrastructure.

The covert, mass release of biological pathogens requires the knowledge and expertise of highly trained interdisciplinary scientists, medical providers, and laboratory personnel for the timely identification of the contagion(s), correct patient diagnoses, and prevention of the endemic proliferation of communicable disease.  Acts of chemical terrorism have similar implications necessitating rapid classification of the hazardous substance(s) and coordinated efforts for rapid response.  Since acts of terrorism have a propensity to illicit widespread panic far beyond the affected population, the expertise of a myriad of health care professionals is needed to conduct appropriate risk communication to the media and the public.  The dissemination of reliable, accurate information can help distinguish a fallacious activity from an actual threat.

The use of explosives by terrorists also poses a litany of public health concerns.  While conventional weapons like rocket-propelled grenades and assault rifles are frequently employed, the threat of suicide bombings, vehicle devices, improvised explosive devices (IEDs), TNT, and plastic explosives is considerably greater for the increased susceptibility for mass fatality and injuries.  The destruction of critical transportation and public health infrastructure is also a major burden as it can prevent or delay the delivery of urgent care.  Body fragmentation and DNA degradation also complicates the identification of deceased victims.  The expertise of medical examiners, fingerprint specialists, radiologists, and forensic odontologists, anthropologists, and pathologists is accordingly required for timely identification and issuance of death certificates to enable the dissemination of benefits to surviving family members and provide the closure they need.  Since the implications of a terrorist attack transcend far beyond the initial impact, acute and long term physical, psychological, and occupational rehabilitation is essential for restoring the health of surviving victims and ensuring a timely return to work and restoration of livelihood.

Food Contaminants Found in the Modern American Diets of Children and their Effects on Child Health

Attention all parents and guardians!  Caretakers of America’s youth play a significant role in determining the future health of this nation. It has become increasingly important to recognize the public health threats posed by microbes, synthetic toxins, hormones, and synthetic compounds utilized in American farm and animal agriculture, food production, and packaging today.  The susceptibility of children to exposures to food contaminants has become one of the most pressing public health issues of today.

WHY ARE CHILDREN A SPECIAL CONCERN?

The potential for adverse health effects in infants and children is especially paramount since organ development occurs most rapidly within the first months and years of life.  A child’s developing nervous system is especially vulnerable as it is less capable of repairing any structural damage caused by toxins in the environment. There are substantial qualitative differences in the capacity for the absorption, metabolism, detoxification, and excretion between children and adults as size, weight, body composition, and physiological functioning all affect pharmacokinetic and pharmacodynamic processes (Alcorn & McManara, 2003)( Jacob, Krishnan, & Venkatesan, 2004).  Infants and children generally absorb and metabolize at a more rapid rate and are less able to detoxify and excrete synthetic compounds due to the immaturity of the kidneys and liver (World Health Organization, 2007).  The manifestation of latent diseases such as cancer, neurodevelopmental impairment, and immune dysfunction is a special concern as many environmentally related diseases develop over prolonged periods of time.  Exposures in childhood may contribute to the presence of disease well into adulthood.

THE EMERGENCE OF MORE TOXIC PESTICIDES

While scientific and technological developments in the agricultural sector have increased rates of food production over the past five decades, the application of agrochemicals such as pesticides has stimulated public health concerns.  Increased pest resistance has led to the emergence of more toxic, ecologically hazardous pesticides, rising operational costs, and higher volumes of overall pesticide usage (Pimentel, 2004).  According to the CDC, approximately 40 organophosphorous insecticides are registered for use in the United States by the EPA and an estimated 73 million pounds (70% of all insecticides) were used in 2001 (2011).  The application of organophosphates, organochlorines, and carbamates by conventional agricultural operations leaves substantial pesticide residues on the produce that children frequently consume.  Dietary risks compound with those of the environment through increased contact with the floor, lawns, and outdoor playing fields.  Despite a long history of pesticide use, the potential for acute and subchronic neurotoxicity, developmental neurotoxicity, and endocrine disfunction still requires systematic review.  The National Cancer Institute has documented an increase in the incidence of all forms of invasive cancer among children over the past 20 years, from 11.5 cases per 100,000 in 1975 to 14.8 per 100,000 in 2004 (2008).  The association of cancer with pesticide residues on food has resulted in a hotbed of controversy among farmers, consumers, scientists, health practitioners, and legislators. 

MICROBIAL FOOD PATHOGENS AND ANTIBIOTIC RESISTANCE

The infiltration of foodborne microbial pathogens poses a plethora of public health challenges to the agricultural, food production, food service, and medical industries.  Antimicrobials such as amoxicillin, ampicillin, erythromycin, neomycin, penicillin, and tetracycline are added to the water and feeds of livestock in “subtherapeutic” levels to promote faster growth and reduce disease-driven losses (Goforth & Goforth, 2000).  Over time, microbes in livestock can become antibiotic-resistant.  As a matter of fact, the reporting of outbreaks due to antibiotic-resistant bacteria has increased each decade since the 1970s and rose by 40% in the last decade ” (DeWaal, Roberts, and Catella, 2011).  The emergence of antibiotic-resistant infections caused by Salmonella typhimureum, Campylobacter, Staphylococcus aureus, and Escherichia coli 0157:H7 increase the potential for disease outbreaks from eating or handling foods contaminated with pathogens in schools, daycare facilities, restaurants, and the home.  The consumption of raw fruits and vegetables increases the risk for infant and child exposures to bacterial and viral pathogens including Listeria monocytogenes, Toxoplasma Gondii, Hepatitis A, Rotaviruses, Enteroviruses, Adenoviruses (CSPI, 2006).  The toll on children’s health attributed to unsafe agricultural, food production, and food handling practices can result in permanent morbidity or mortality.

THE LINK BETWEEN SYNTHETIC CHEMICALS AND ADHD

The ingestion of synthetic chemicals used to enhance the appearance, flavor, and shelf life of food is yet another area of concern.  Artificial flavor enhancers, colors, dyes, ripening agents, sweeteners, and preservatives that are commonly found in the modern American diets of children have been linked to Attention Deficit Hyperactivity Disorder (McCann, et al, 2007).  A study conducted by the University of Southhampton found that artificial colors and sodium benzoate preservatives in the diet resulted in increased hyperactivity in 3-year-old and 8/9-year-old children (McCann et al., 2007).  The detection of plastic pollutants (phthalates) such as Bisphenol A (BPA) in the manufacturing of baby bottles, reusable cups, and lining of food and beverage containers poses further concern (HHS, 2012) (EPA, 2007).  Phthalates have been detected in foods that children most frequently consume such as milk, cheese, meat, margarine, eggs, cereal, baby food, and infant formula (EPA, 2007).  The phthalates, diethylhexyl phthalate (DEHP), dibutyl phthalate (DBP), and butyl benzyl phthalate (BBP), have been closely associated with adverse developmental and reproductive health effects (Fabjan, Hulzebos, Mennes, & Piersma, 2006).

INCREASED USAGE OF HORMONES AND ANTIBIOTICS

The growing demand for affordable meat and dairy products in America has led to the utilization of hormones and antibiotics to produce meat, eggs, and milk as rapidly and cheaply as possible.  The FDA approves a number of steroid hormones to increase the growth rate in growing cattle and sheep as well as Recombinant Bovine Growth Hormone (rBGH) to increase milk production in dairy cattle.  While the association of hormones with the early onset of puberty and cancer has yet to be scientifically proven, the uncertainty has prompted the banning of rBGH in Japan, Canada, Australia, and New Zealand and the use of all hormones in beef by the European Union.  Approximately 70% of all antibiotics used in the United States are administered to healthy livestock at low doses to promote faster growth and to mitigate for unsanitary living conditions, especially in Concentrated Animal Feeding Operations (CAFOs), (NRC, 2007).  This practice has contributed to an epidemic of antibiotic-resistant infections in America. The CDC estimates that 2 million antibiotic-resistant infections and 90,000 deaths occur annually (Pew Commission on Industrial Farm Animal Production, 2008).  Children are especially vulnerable to this health risk.

THE RISE OF OBESITY AND DISEASE IN AMERICAN CHILDREN

Pesticides, growth hormones, and other various chemicals that are commonly found in America’s conventionally raised meats, fruits, and vegetables contain obesogens that disrupt normal functioning of the endocrine system, causing weight gain.  According to data from the National Health and Examination Survey (NHANES), “approximately 17% (or 12.5 million) of children and adolescents aged 2—19 years are obese” (CDC, 2011).  Sadly, the prevalence of obesity among children and adolescents has nearly tripled since 1980 (CDC, 2011).  The principal causes of sickness, disability, and death in children in the United States today are chronic illnesses and rates of many of these diseases are high and rising (Landrigen & Goldman, 2011). “Toxic chemicals in the environment are making important contributions to these disease trends” (Landrigen & Goldman, 2011).

THE ROLE OF PARENTS IDENTIFIED

The foundation for a healthy diet is framed at a young age and developed through the learned behaviors and role modeling of parents and siblings.  Since children can experience great difficulty comprehending the impact of future negative health effects, interventions should begin in the home environment.  The education of parents and guardians is therefore imperative so as to increase overall awareness for food-related health risks and to augment informed purchasing, handling, and preparation of food and packaging.  Improving the modern diets of children will augment efforts to reduce the prevalence of foodborne infections, obesity, and acute and chronic diseases in America today and in the years to come.

Aquarion Water Company: A Look into the Challenges Facing Connecticut’s Largest Water Utility

The Aquarion Water Company (AWC) is Connecticut’s largest water utility (AWC, 2011).  Headquartered in Bridgeport, the company serves more than 580,000 people in 39 cities/towns throughout Connecticut as well as five in Massachusetts and three in New Hampshire (AWC, 2011).  Aquarion’s presence in the public water supply business is impressive.  Established in 1857, it remains “the largest investor-owned water utility in New England and among the seven largest in the U.S” (AWC, 2011).  Despite exhaustive research efforts, Aquarion Water Company’s “Capital Improvement Plan” could not be located.  This may be attributed to the company’s broad scope of operations which involves an abundance of communities across several states.  Detailed information regarding local infrastructure and improvement projects; however, is readily available.  This includes upgrades in various parts of Connecticut including Greenwich, Stoningham/Groton, and Brookfield.  These provide adequate insight into the company’s broad scope of impact in addition to investment and planning challenges posed by infrastructure improvements of the past, present, and future.

While Aquarion’s undergoing capital improvements are colossal and costly, they are absolutely necessary.  Given the scope of service and the amount of infrastructure and equipment involved, the company must satisfy its responsibility to provide a magnitude of customers with an ample supply of clean, potable water.  In consideration of the company’s aging infrastructure, the urgency for capital improvements is a matter of both public health and safety. As such, the replacement of aging infrastructure continues to be an integral part of the company’s capital project work.   Infrastructure improvements and expenditures are extensive, due in part by Aquarion’s recent growth via the acquisition of smaller water utility companies.

Acquisition expenditures resulting from the rehabilitation of a former company’s infrastructure assets are magnanimous.  Since 2008, Aquarion has invested $25 million to upgrade the Putnam Filter Plant in Greenwich, CT.  Following its purchase of Connecticut American Water Company in 2002, Aquarion immediately began prioritizing capital improvements to address critical infrastructure deficiencies.  The urgency was justified as the plant had not undergone any major improvements since the 1950s (AWC, 2011).   From 2002 to 2008, Aquarion invested $6 million to the Putnam facility, the town’s largest source of water, in order to rehabilitate filters, install stand-by power, and upgrade electrical service to ensure a supply of 20 million gallons of water a day for consumption and fire safety (AWC, 2008).  Improvements also included the replacement of a failing 1920s-era treatment clearwell to meet supply demands and comply with health department standards (AWC, 2008).

Aquarion’s responsibilities recently extended to Brookfield’s Greenridge water system.  On November 2, 2011, Connecticut’s Public Utility Regulatory Authority and the Department of Public Health approved Aquarion’s proposal to deliver uncontaminated water to the Greenridge district, whose previous supplier had filed to cease operations.  According to decision drafted by the Connecticut’s Department of Environmental Energy and Protection (DEEP), Aquarion’s estimated total cost for the proposed water main and associated improvements totaled $3.25 million including $564,000 in improvements made by United Water, the previous supplier (DEEP, 2011).  Aquarion also continues to upgrade its infrastructure in the Stonington/Groton, CT area where it began relining the 21 year old, 8-inch water mains at Lords Point this past August (AWC, 2011).  Aquarion’s capital improvements reflect its self-proclaimed commitment to ensuring the quality of its water systems and delivering uninterrupted service.

All across America, drinking water infrastructure is nearing or exceeding its life expectancy and systems are failing.  Connecticut is certainly no exception.  According to a 2008 survey conducted by the American Society of Civil Engineers (ASCE), “Connecticut’s drinking water infrastructure needs an investment of $653 million over the next 20 years” (2010).  Accordingly, Aquarion’s capital improvement spending is expected to considerably increase over the next few years to achieve the timely replacement of problematic water mains, flow-management valves, fire hydrants, meters and leak-detection equipment (AWC, 2011).  Aquarion’s spending has been recently amplified and accelerated due to the acquisition of smaller, less capable utilities starved of the funding necessary to manage, maintain, and replace their aging water infrastructure.  This poses new challenges as Aquarion must familiarize itself with the water main condition so as to facilitate leak detection and prevent breakage.

Buried infrastructure is especially vulnerable as maintenance and repairs are substantially expensive and disruptive.  The closure of a major intersection and a street lane in Bridgeport caused by a water main break on November 17, 2011 is one such example.  According to the Connecticut Post, “the intersection of State Street and Broad Street has experienced three water leaks in the past six weeks,” a clear indication of the challenges posed by the city’s aging infrastructure, comprised of pipes that are 90 years old (2011).  Bruce Silverstone, a company spokesman for Aquarion Water Company, commented:”It’s difficult, a very difficult area because of all the infrastructure that’s underground, there.  It is an unusual situation. When these breaks take place, we must replace them on kind of a piece-meal basis” (Craig, 2011). Since budget restrictions prevent total replacement, the company is combating problems as they arise. Experts argue; however, that “the ‘fix-on failure’ approach is no longer working” (Kinge, 2009).

Aquarion also faces water supply challenges posed by stream flow regulations required to be developed by Section 26-141b of the General Statutes.  Passed in 2005 by the Connecticut General Assembly, the act requires the DEEP to collaborate with the Department of Public Health and stakeholders to “update standards for maintaining minimum flows in rivers and streams” so as to achieve a balance in water usage that respects river and stream ecology, wildlife, and recreation while providing for public health and safety, industry, agriculture, water supply, and other lawful water uses (DEEP, 2011).  While Aquarion recognizes its responsibility for “conservation and natural resource management,” George Logan, its Director of Capital Planning, testified that the proposed regulations “did not adequately provide for public water supply” (Testimony, n.d.).  According to Logan, “more than nine million gallons per day would have been lost, approximately 10% of our total water supply” (Testimony, n.d.).  Company costs would have also been markedly affected, requiring approximately $100 million to modify its facilities, an investment equivalent to 3 years of total capital spending (Testimony, n.d.).  This would divert monetary allocations from necessary infrastructure improvement.  Logan warns that that the investment “would result in an incremental rate increase of approximately 10%, at a time when personal and municipal budgets can least afford to pay it” (Testimony, n.d.).  Added to a lack of infrastructure funding is the elevated price of electricity as Connecticut has the second highest electric rates in the country (McCarthy, 2008).

To finance its capital investments, Aquarion initiated a customer surcharge in April of 2009 which has steadily increased since its inception (AWC, 2011).  The surcharge bill, referred to as Water Infrastructure and Conservation Adjustment (WICA), was approved in 2007 by the Connecticut Legislature to help fund the timely replacement of water distribution pipes and related infrastructure that have either reached the end of their useful life or threaten water quality or service (AWC, 2011).  As of July, 2011, the current WICA surcharge is 0.32% (AWC, 2011).  The company recently applied for a surcharge increase to 0.35% which will take effect on April 1, 2011, if approved (AWC, 2011).  The WICA is subject to change throughout the year pending infrastructure improvements and approval by Connecticut’s Public Utilities Regulatory Authority (AWC, 2011).

In an interview conducted by Global Water Intelligence (GWI), Frank Firlotte, Aquarion’s CEO, justifies the rate increases, attributing them to the company’s rising opex.  According to Firlotte, an excess of $100 million has been invested in Connecticut alone with 40% of the hike related to capital investment, another 40% to escalating operating expenditures, and the remainder to falling volumetric sales (GWI, 2010).  Since Aquarion currently operates on the basis of a 45/55 debt to equity ratio and a Return on Equity (ROE) of approximately 10%, the utility is able to handle additional debt to fund investment in the rate base (GWI, 2010).  Although Firlotte is hopeful that the Connecticut Department of Utility Control will award Aquarion an ROE above 9.75% in favor of his company’s “efficiency,” “service delivery,” and “operational metrics,” he acknowledges that the system of regulation is not based on performance as it is in other countries (GWI, 2010).

The former director of Yorkshire Water in England, Firlotte is frustrated by the reluctance of local government to relinquish water provisions (GWI, 2010).  As the company sets its sites on continued expansion, it must gain appropriate regulatory approval and acquire adequate infrastructure improvement capital.  In the era of failing water infrastructure, Aquarion is destined to encounter an increasingly challenging process.  As a nation that dedicates only 2.4% of its GDP to infrastructure, a continued lack of financial commitment will further compromise capital improvements, the economy, the water supply, and the public health of a bustling American population (ASCE, 2011).  Comprehensive assessment, planning, and funding over time are the most prudent solutions to this pressing issue.

Should We Regulate the Usage of Mobile Sources of Air Pollution?

While the idea of regulating the amount of usage of mobile sources of air pollution seems promising, it is very unrealistic.  Americans take great pride in their cars and restricting their usage would not be well received.  Also, regulations would also be extremely difficult to enforce.  How are we to enforce the usage of leaf blowers?  Do we start placing usage meters on mobile equipment?  Do we establish a municipal police force solely dedicated to mobile source pollution?  What would this do to our taxes?  What rights would this type of “force” have to enter the property of one’s home without the appropriate warrant?  This would be an overly-bureaucratic government!

We are a mobile populace who relies heavily on our cars and other forms of mobile transportation to get us to a wide variety of environments from the workplace to vacation destinations.  Limiting their use would inflict further wound to a suffering American economy. Now let me be clear, I am not advocating a public free-for-all.  Instead, I propose that we regulate the vehicles and equipment themselves.

Some of you may be thinking, “What about heavily polluted areas?!”  To this I must ask, “How many leaf blowers have you seen being operated in New York City?”  Also, many people do not own cars because there isn’t a compelling need for one.  My brother is one of them.  He sold his car when he moved to Manhattan.  Of course, he always takes mine when he comes home but that is an entirely different topic!  You would also be hard-pressed to find any lawn mowers operating in the City as well.

I am sure many of you have been squeezed into a subway at one point or another.  I cannot help but wonder how much air pollution is actually prevented through use of public transportation in NYC.  My efforts to find research quantifying this has unfortunately failed.  Understandably, this is very difficult to estimate.  However, I did find that gasoline consumption in NYC is at the same rate the national average was in the 1920s (Jervey, 2006).  In fact, NYC’s dense population and low automobile dependence help make New York among the most energy efficient in all of the United States (Owens, 2004).

My point is there must be a balance achieved between usage and toxic emissions of mobile sources of air pollution which can be most efficiently achieved through pragmatic, enforceable regulations.  Examples include improving fuel economy and minimizing emissions through idling policies.  Most states have adopted the latter.  It is also up to the consumer to minimize emissions.  Driving fewer miles and purchasing more fuel efficient cars can indeed save Americans a lot of money.  With the prices of gas expected to soar this summer, these options can be advocated for their advantages to both the consumer and the environment.

Fortunately, the government is doing something to regulate mobile sources of air pollution.  The EPA finalized a rule in February 2007 to reduce hazardous air pollutants from mobile sources by limiting the content of benzene in gasoline and reducing toxic emissions from passenger vehicles and gas cans (EPA, 2012).  Since mobile sources are responsible for the majority of benzene emissions, this is a step in the right direction.  According to EPA estimations, this rule would “reduce total emissions of mobile source air toxics by 330,000 tons and VOC emissions (precursors to ozone and PM2.5) by over 1 million tons” by 2030 (EPA, 2012).  This is a considerable improvement.  The EPA also regulates emissions from highway vehicles and nonroad equipment and controls emissions of hydrocarbons, particulate matter, and nitrogen oxides to significantly reduce toxic emissions (EPA, 2012).  In addition, the EPA is currently developing programs to provide further control of emissions from nonroad gasoline engines and diesel locomotive and marine engines (EPA, 2012).  To reduce the overall risks to communities, the EPA has developed several programs including Clean School Bus USA, the Voluntary Diesel Retrofit Program, and National Clean Diesel Campaign (EPA, 2012).

We have indeed come a long way in controlling mobile sources of air pollution.  As a more informed and environmentally conscious American population continues to emerge, I predict that it will become progressively easier to address the problems of air pollution in the future.  Continued regulation of the automobile manufacturing industry will also continue to modify and adapt its cars to be more fuel efficient and less toxic to the environment.  While I think that the use of electric cars by everyone is a long way off, it is an inevitable possibility we must all are prepare for.

CONSUMERS BEWARE: The Dangers of Endocrine Disruptors (EDCs) & Pharmaceuticals in Personal Care Products

Just when you thought it was safe to drink the water, look no further than your medicine cabinet.  Concerns continue to  build over the public health impact of our water supply.

What are common chemicals/classes of EDCs?

According to the National Institute of Environmental Health Sciences (NIEHS), chemicals/classes of endocrine disruptors include “pharmaceuticals, dioxin and dioxin-like compounds, polychlorinated biphenyls, DDT and other pesticides, and plasticizers such as bisphenols (2011).”  Disturbingly, endocrine disrupting chemicals (EDCs) can be found in literally thousands of common products including plastic bottles, metal food cans, detergents, flame retardants, food, toys, cosmetics, and pesticides (NIEHS, 2011).  The broad presence of EDCs in everyday products increases the likelihood for interference with the body’s endocrine system to produce a number of adverse developmental, reproductive, neurological, and immune effects (NIEHS, 2011).  While the field of endocrine disruption is fairly new, studies are being conducted to confirm whether endocrine disruptor exposure may reduce fertility and increase the incidence of endometriosis and some cancers (NIEHS, 2011).  The future of this field will undoubtedly yield some extraordinary findings to ultimately increase the public’s awareness and impact future manufacturing processes.

How do EDCs get into receiving water bodies?

Endocrine disruptors infiltrate receiving waterways via personal, pharmaceutical, and agricultural applications.  Human activity, residues from pharmaceutical manufacturing and hospitals, illicit drugs, and veterinary drugs contribute a variety of pharmaceuticals and personal care products (PPCPS) to receiving waters in the form of prescription and OTC therapeutic drugs, veterinary medicines, fragrances, cosmetics, sun-screen products, diagnostic agents, and vitamins (EPA, 2010).  Agricultural applications also supply receiving waters with a plethora of chemicals suspected of acting as endocrine disruptors including insecticides, herbicides, fumigants and fungicides (NRDC, 1998).  Individuals supply wastewater treatment plants with PPCPs through excretion, bathing, and disposal of medications into the sewer system and trash (EPA, 2010).  Discarding unused medications and personal care products into the toilet is an irresponsible yet common practice that exacerbates the problem.  Since PPCPs do not easily dissolve or evaporate at typical temperatures and pressures, they can infiltrate soils and aquatic environments with ease (EPA, 2010).  PPCPs that are not broken down and processed by the body or degraded by the environment enter domestic sewers and remain untreated.  PPCPs also have the capacity to penetrate soil and aquatics via sewage, biosolid applications, and irrigation with reclaimed water (EPA, 2010).

Endocrine disruptors are also introduced through spray-drifts, runoff from livestock and pesticides, and leachate from municipal landfills and septic systems (Center for Biological Diversity, n.d.).  The widespread use of steroid hormones in confined animal feeding operations (CAFOs) is of particular concern for the introduction of  endogenous steroids, exogenous compounds,  pharmaceuticals, and anabolic growth promoters like trenbolone and melengestrol  into receiving waters (Kolodziej, n.d).  The potential for CAFOs to elevate the concentration of steroids in watersheds is considerably higher with the occurrence of extreme precipitation.  The presence of synthetic steroid hormones such as trenbolone, melengestrol, and zeranol, used to promote rapid livestock growth, increases when the accumulation of animal wastes is not controlled and a direct pathway for wastes to reach surface waters exists (Kolodziej, n.d.).

Why are EDCs of particular concern to regulators?

Since municipal sewage treatment plants are not equipped for the removal of PPCPs and other unregulated contaminants, the presence of endocrine disrupting chemicals (EDCs) in the watershed poses a number of public health concerns.  While the measure of health risks has yet to be quantified, growing evidence suggests that EDCs can produce adverse health effects in humans, wildlife, fish, or birds including developmental, reproductive, neural, and immune problems (EPA, 2010).  This can adversely affect fish ecology and threaten the survivability of species.  A panel of experts convened by the NIEHS and the National Toxicology Program (NTP) found ‘credible evidence’ for the effect of hormone-like chemicals on test animals’ bodily functions at levels below the ‘no effect levels’ established by traditional testing (EPA, 2010).  There is also substantial research in experimental animals and wildlife associating EDCs with reduced male fertility and number of males born, male organ defects, female reproductive diseases, and increases in mammary, ovarian, and prostate cancers (EPA, 2010).  The storage of endocrine disruptors in fat cells can also have long-term negative health consequences.  Exposures to Bisphenol A and other EDCs with estrogenic activities increase the detrimental health effects of cancer and obesity (EPA, 2010).  The transgenerational effects of EDCs is also a focus of study as NIEHS research has found that fertility defects have been passed to subsequent generations (EPA, 2010).    

With the omnipresence of Bisphenol A (BPA), Di (2-ethylhexyl) phthalate, and phytoestrogens in many common, everyday products, the simultaneous exposure to multiple EDCs elevates concerns (EPA, 2010).  As of 2007, over 100 individual PPCPs have been identified in addition to antibiotics and steroids that have been found in both environmental samples and drinking water.  Simultaneous exposure occurs through one’s diet and the medications and cosmetics used.  Studies are now focusing on the association between EDCs and resistance to antibiotic drugs as well as special scenarios involving fetal exposures (EPA, 2010).  Further studies are warranted to investigate the acute and long term effects of EDCs as it remains a pressing and highly controversial public health issue.

Considerations for regulating EDCs in wastewater and/or receiving water bodies

Prior to designing regulations, policy-makers must consider scientific uncertainties associated with EDCs and their potential health effects in animals and humans.  Stringent regulations must rely on a definitive classification system for endocrine disrupting chemicals so as to implement appropriate restrictive measures.  The regulation process necessitates further research to identify conclusive evidence to considerably minimize the controversy that surrounds this issue.  This will require the expertise of a broad variety of experienced medical scientists and environmental health specialists along with substantial research investment capital and time for further research completion.  The implementation of appropriate regulations should reflect a close collaboration between policy makers, field experts, and the public at large.

Policy makers must also consider the level of vulnerability of the population exposed to EDCs and their potential impacts when implementing regulations.  This can be based on a variety of factors including the average age, diet, occupation, and prevalence of obesity, cancers, and metabolic diseases.  Other factors include the presence of major industries within a relevant geographical area.  Infants, young children, and the elderly are special populations who exhibit increased susceptibility to EDCs due to inferior immune systems.  Special considerations must also be considered for pregnant women and individuals with immune disorders/diseases such as AIDS.  Obese individuals and people suffering from cancer are of particular concern as increased EDCs exposure can manifest or exacerbate symptoms associated with endocrine system abnormalities.  One’s occupation is also a critical factor as manual laborers face increased frequencies and durations of EDC exposure.  The presence of industries and the type of manufacturing processes and chemicals used are especially pertinent when initiating regulatory legislation to decrease the overall prevalence of EDC exposures among workers and citizens in the environment in which they live.  Regulations should therefore reflect all of these factors to minimize the overall risk to any given population.

The potential impacts on businesses should also be considered.  In a fragile American economy, the development of new restrictions would pose increased financial and administrative burdens, threatening the survivability of businesses.  The alteration of manufacturing and agricultural processes to incorporate new raw materials to eliminate or reduce the release of EDCs could pose considerable financial losses.  Similarly, provisions that necessitate wastewater treatment to improve levels of EDCs in effluent discharges or measures to decrease employee exposure could prove to be exceedingly costly.  Also, company management plans for the monitoring of EDCs would necessitate comprehensive recordkeeping and reporting, requiring additional manpower and staff.

Developing Community Coalitions to Combat Childhood Obesity: Key Stakeholders Identified

As a professional chef, trainer, and Health Coach, combating the epidemic of childhood obesity is very near and dear to my heart.  The statistics regarding trends in childhood obesity speak volumes.  According to data from the National Health and Examination Survey (NHANES), “approximately 17% (or 12.5 million) of children and adolescents aged 2—19 years are obese” (CDC, 2011).  Shockingly, the prevalence of obesity among children and adolescents has nearly tripled since 1980 (CDC, 2011).  The American Heart Association (AHA) warns that although atherosclerotic disease does not clinically manifest until adulthood, epidemiological studies and autopsy data have indicated that “ the atherosclerotic process, as evidenced by functional and morphological changes in the heart and blood vessels, begins early in childhood” (AHA, 2011).  Since obese children are more susceptible to a myriad of diseases, including cardiovascular disease and Type 2 diabetes, this will undoubtedly increase the burden on public health in America.  This necessitates immediate interventions in communities all throughout America in both home and school environments.

A solution to the problem is certainly not easy.  As noted in the study provided, socioeconomic play a definitive role.  Nutritious foods, fitness and sports programs, exercise clothing, and equipment all require sufficient finances.  A lack of supermarkets in the community can significantly reduce adequate intakes of fresh fruits and vegetables.  Families surviving on low incomes, especially those in low, socio-economic communities may have little funding to support the continued purchase of a wide variety of healthy and organic foods.  Similarly, participation in active forms of recreational activities can intensify financial hardship amongst struggling families.  The absence of ample sidewalks as well as the presence of city pollution can deter or even prohibit exercise throughout the community.  Neighborhoods in which public parks and recreational facilities are unsafe and/or overcrowded may further limit opportunities for physical activity.  The rising prevalence of childhood obesity is also threatened by a troubled economy.  Recent budget cuts in school districts compromise funding for extracurricular activities.  Inadequacies in nutrition and physical education in provided at school place an even greater responsibility on the parent(s)/guardian(s) to imbue the foundations for healthy eating and regular physical activity in children.

Coalitions for resolving childhood obesity should implement an evidence-based approach that initiates with a review of pertinent literature on trends and statistics.  The U.S. Department of Health and Human Services and the United States Department of Agriculture are two organizations that have produced an ample amount of reliable information.  The Bogalusa Heart Study and a USDA Economic Research Service study have both attempted to link obesity to children’s diet.  Specifically, the Bogalusa Heart Study analyzed the eating patterns of children over twenty years from 1973-1994 using cross-sectional surveys given to ten year old children.  The USDA Economic Research Service Study focused on the link between fruit consumption and BMI using a cohort of children between five and eighteen years of age from 1994 to1996.  Although both failed to find a direct link between children’s diets and the premature onset of obesity, the sources provide a basis for intervention initiatives and the task at hand.

PARENTS

The identification of key stakeholders is a necessary preliminary step when developing an intervention.  Since children are the target of the intervention, it is imperative that parents be considered the most significant stakeholders.  The foundation for dietary and physical habits is framed at a young age and is developed through the learned behaviors and role modeling of parents and siblings.  Food availability and selection is almost entirely determined by the child’s parent(s)/guardian(s).  Unhealthy dietary patterns during childhood such as increased frequency and duration of meals, enormous portion sizing, and food associations with punishment and/or reward can germinate.  An emphasis on sugar-sweetened, processed, and/or high fatty foods in the home can resonate far into adulthood.  The Bogalusa Heart Study analyzed the eating patterns of children over twenty years from 1973-1994 using cross-sectional surveys given to ten year old children.  The study found that “offspring who had a parental history of diabetes were significantly more obese, irrespective of age” (Bao, Wattigney, and Berenson, 1995).

HEALTH PRACTITIONERS

Pediatricians, physician assistants, and nurses play a major role in the identification of high risk populations and the dissemination of pertinent health information to parent(s)/guardian(s).  Practitioners in the public and private sectors engaged in prevention and wellness programs and activities are also essential.  These individuals can perform the necessary screening for obesity at regular checkups in a clinical or school setting.  The school nurse is especially important as they can identify potential health risks in the school environment.  A school nurse is more accessible to a child who reports to school on a daily basis.  He or she comes in contact with school children more frequently than pediatricians at regular “check-ups.”  They can conduct invaluable medical surveillance to identify children at risk and to oversee school programs for improving physical activity and nutrition.  They can also serve as a liaison between a child’s pediatrician and his or her parents, alerting parents to risk factors including high BMIs and Waste-to-hip ratios.  As coalition members, health practitioners play critical roles in explaining, advising, and supporting parents in improving their child(ren)’s health and wellbeing.

GOVERNMENT OFFICIALS

Government officials serve as the leading agents for convening coalitions and securing the necessary funding, resources, and contacts to support the coalition.  As the Mayor of New York City, Michael Bloomberg can obtain pooled members and external resources in the form of government funding and grants.  Government officials play an integral role in obtaining State and Federal funding/assistance for making large-scale community interventions possible.  In a nation that is suffering economically, our leadership is tasked with prioritizing the needs of the community.  This is a daunting endeavor and the topic of much debate among constituents and needy populations.  Coalition members representing diverse interest groups and organizations committed to combating childhood obesity can come together to lobby important leaders of government to help resolve this pertinent issue.  They can also implement effective policies such as banning hydrogenated foods and including nutrition facts on menus.  These are powerful initiatives to promote positive change.

SCHOOL OFFICIALS

Efficacious interventions that support healthy behavior change need to focus on educating children.   Without an acceptable knowledge base, unhealthy behaviors go uncorrected and the child remains ignorant to the negative health consequences throughout development and life.   Local school and public officials and directors of community-based organizations are integral to providing an age-appropriate knowledge base and opportunities for sufficient physical activity.  School principals, teachers, and physical education instructors can collaborate to provide programs that support the identification of healthy foods, portion sizing, and obesity-related diseases.

DIRECTORS  OF COMMUNITY-BASED ORGANIZATIONS

After school programs that allow for ample amounts of exercise and recreational activities provide opportunities for fitness and social interaction as opposed to sedentary behaviors practiced in the home environment.  Fitness and youth directors at the local YMCA support various programs that motivate and inspire children to engage in healthy physical activities.  These facilities offer programs that are more accessible to children when compared to private health clubs and corporate gyms.  In a nation of “latch-key” children and busy parents, after school programs can fill the void in physical activity that is sickening our children.

VOLUNTEERS

In lower socioeconomic areas, volunteers may be necessary to bridge the gap between these programs and a lack of funding.  Volunteer leaders and paid staff can facilitate the collaborative process and coalition functioning (Glanz, et. al, 2008).  Tax incentives to these individuals can elicit further involvement.

HEALTH EDUCATORS

Health educators can provide an additional means for educating parents and guardians on the dangers of obesity in children.  They can build on the information and support provided by health practitioners and school educators to parents.  They can also advise school officials on the proper planning and implementation of appropriate educational programs by identifying the issues that are most important to guide interventions.  Health educators are equipped at identifying ways to implement behavior change with minimal resources.  They can help remove barriers attributed to a lack of finances and adequate food markets by helping parents identify healthy, affordable options.  They can also advise parents on fitness activities to involve children in the home.  Whether advising school officials or parents on the preparation of healthy foods and cooking techniques or identifying kid-friendly forms of exercise, health educators are key contributors of valuable information and resources.

Proper planning would be centered on the evaluation of needs assessment data concerning children in a particular community.   A historical understanding of the community is imperative as a successful intervention strategies build on community strengths.  This can identify community context, the characteristics that catalyze or inhibit coalition function and influence how the coalition develops such as geography, demographics, politics, social capital, and community readiness (Glanz, et.al, 2008).  The procurement of data pertaining to social indicators such as home and built environments as well as epidemiologic indicators including nutrition-related disease prevalence would facilitate assessment and planning strategies.  Behavioral risk factors involving overnourishment and lack of physical activity should be investigated along with the knowledge, attitudes, and skills necessary for improving dietary and fitness habits should also be considered.  Additionally, community needs and access to health care are important for a thorough analysis. This would improve community capacity to improve its ability to identify, mobilize, and address childhood obesity.

Structures such as formalized organizational agreements and coalition rules, roles, objectives are essential.  Objectives and goals should be clear and measurable so as to determine short and long-term health outcomes which are vital for determining program success.  Objectives should be prepared by experts with substantial experience in the area of childhood obesity.  Objectives should be specific, measurable, attainable, realistic and timely.  Each should have a reliable data source, baseline measure, and targets for improvements to be achieved over a predetermined time period.  They should focus on the reduction in prevalence of overweight/obese children, especially those younger than five years of age.  Objectives should also address the social determinants of health to eliminate health disparities. Coalition operations and processes should facilitate communication between coalition members and staff for decision making, conflict management, organization, and member engagement (Glanz, et, al 2008).  This maximizes member engagement, the extent of participation, commitment, and satisfaction of the members of the coalition to ultimately strengthen the coalition (Glanz, et. al, 2008).

An evaluation of the intervention should also be planned.  The evaluation should determine the number of children served, the time period of service, and the consistency of the intervention’s implementation.  It should also include an assessment of performance of various members of the staff.  Interventions at the community level can potentially require an evaluation of multiple individuals in various sites.  Ideally, all outcomes should be measured at all level of the causal continuum to determine the overall efficiency and effectiveness of the intervention.  Community participation including work conducted by existing community organizations as well as volunteer contributions should not be excluded.  This will provide valuable information for initiating future interventions.

LAUNCHING BLOG NOW!

Hello and welcome to my blog!  I am a professional chef, personal trainer, and an American Council on Exercise-certified Health Coach.  I founded The Chef N’ You LLC in 2010 which offers sound, balanced, weight-management programs and culinary guidance to individuals wanting to achieve a healthier lifestyle.  My company is an all-encompassing reflection of my background in exercise science and public health, competitive athletics, culinary training, and an enthusiasm for helping people improve the quality of their lives through proper nutrition, exercise, and lifestyle change.

I am a former three-time United States Lifesaving Association (USLA) National Champion and silver medalist with over 15 years experience in competitive swimming and various sport disciplines.  Elite competition demanded superior physical conditioning and the implementation of a nutritious diet to enhance performance.  These experiences served as the foundation for my interest in public health and preventative medicine.

I began my journey at The George Washington University’s School of Public Health and Health Services where I received a Bachelor of Science degree in Exercise Science.  As an undergrad, I was a dedicated member of the Battalion of Midshipman in the University’s Naval Reserve Officers Training Corps and trained for a potential career in Special Operations.  I served as the Assistant Athletics Officer and Orientation Instructor, indoctrinating 4th Class candidates at US Marine Corps Base Quantico.

Following a fervent passion for food and cooking, I later enrolled at The Culinary Institute of America (CIA) in Hyde Park, NY where I received an Associate in Occupational Studies degree in Culinary Arts, graduating with honors.  This remains to be one of my proudest accomplishments as cooking at the CIA is far from easy!  As a student, I obtained a ServSafe Food Protection Manager certification for the safe receipt, preparation, and service of food.  A strong understanding of culinary skills, techniques, and fundamentals allows me to prepare nutritious, high quality, meals without compromising flavor or substantiality.

 

My continued passion for public health advocacy led me to New York Medical College where I earned a Master in Public Health degree in Environmental Health Sciences, graduating with high honors.   As an inductee of the US Navy’s Health Services Collegiate Program (HSCP), I was commissioned a Lieutenant Junior Grade upon graduation and entered the United States Navy’s Medical Service Corps as an Environmental Health Officer.   Following Officer Development School in Newport, RI, I reported to the Public Health Department, Preventative Medicine Unit at Naval Branch Health Clinic – Groton located at Naval Submarine Base New London.   I am serving to prevent and control the incidence and spread of disease amongst our Sailors, Marines, and their families.  Go Navy!

When not working, I enjoy playing with my two dogs Brunello and Bianco.  Brunello is a curious Puggle and Bianco is a vivacious yellow Labrador Retriever.  They have completely opposite personalities but both share an avid love of all food, even bananas!  I also like to devote time to my favorite charities.

Nutrition, fitness, and environmental health are enormously critical components of public health!  I focus on empowerment and prevention to assist my clients with employing healthy behaviors to improve their health, wellbeing, and overall quality of life.  My blog is a culmination of my studies and experiences of the past and present.  Feel free to read and explore my blog.  I look forward to interacting with all of you!

Yours in Health,
