Disaster medicine is the area of medical specialization serving the dual areas of providing health care to disaster survivors and providing medically related disaster preparation , disaster planning , disaster response and disaster recovery leadership throughout the disaster life cycle . Disaster medicine specialists provide insight, guidance and expertise on the principles and practice of medicine both in the disaster impact area and healthcare evacuation receiving facilities to emergency management professionals, hospitals, healthcare facilities, communities and governments. The disaster medicine specialist is the liaison between and partner to the medical contingency planner , the emergency management professional, the incident command system , government and policy makers.

99-488: Disaster medicine is unique among the medical specialties in that unlike all other areas of specialization, the disaster medicine specialist does not practice the full scope of the specialty everyday but only in emergencies. Indeed, the disaster medicine specialist hopes to never practice the full scope of skills required for board certification. However, like specialists in public health , environmental medicine and occupational medicine , disaster medicine specialists engage in

198-549: A mass casualty incident . In a poll by the American College of Emergency Physicians (ACEP) in May 2018, 93% of doctors said their US emergency rooms were not fully prepared for medical surges. 6% said their emergency departments were fully prepared. Hospitals preparation to manage an increase in patient volumes has been highlighted in recent times due to different man-made or natural-caused disasters. The Covid-19 pandemic

297-460: A basic level of medical care and disease prevention. A major public health concern in developing countries is poor maternal and child health , exacerbated by malnutrition and poverty coupled with governments' reluctance in implementing public health policies. Developed nations are at greater risk of certain public health crises, including childhood obesity, although overweight populations in low- and middle-income countries are catching up. From

396-620: A basic level of medical care and disease prevention. As a result, a large majority of disease and mortality in developing countries results from and contributes to extreme poverty . For example, many African governments spend less than $ 100 USD per person per year on health care, while, in the United States, the federal government spent approximately $ 10,600 USD per capita in 2019. However, expenditures on health care should not be confused with spending on public health. Public health measures may not generally be considered "health care" in

495-410: A component of preventive medicine and public health. It is implemented as part of primary care rather than a specialty in its own right. Valles argues that the term social medicine has a narrower and more biomedical focus than the term population health. The purpose of a public health intervention is to prevent and mitigate diseases, injuries , and other health conditions. The overall goal

594-441: A country's overall health care system. Many interventions of public health interest are delivered outside of health facilities , such as food safety surveillance, distribution of condoms and needle-exchange programs for the prevention of transmissible diseases. Public health requires Geographic Information Systems (GIS) because risk, vulnerability and exposure involve geographic aspects. A dilemma in public health ethics

693-653: A disaster and emergency medicine discussion and study group under the American Medical Association (AMA) in the United States as well as groups in Great Britain, Israel and other countries. By the time Hurricane Andrew struck Florida in 1992, the concept of disaster medicine was entrenched in public and governmental consciousness. Although training and fellowships in disaster medicine or related topics began graduating specialists in Europe and

792-668: A form of "health fascism" by a number of scholars, objectifying the individual with no considerations of emotional or social factors. When public health initiatives began to emerge in England in modern times (18th century onwards) there were three core strands of public health which were all related to statecraft: Supply of clean water and sanitation (for example London sewerage system ); control of infectious diseases (including vaccination and quarantine ); an evolving infrastructure of various sciences, e.g. statistics, microbiology, epidemiology, sciences of engineering. Great Britain

891-499: A handful of people or as large as a village or an entire city. The concept of health takes into account physical, psychological , and social well-being . As such, according to the World Health Organization , "health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". Public health is related to global health which is the health of populations in

990-463: A million avoidable child deaths each year. Intermittent preventive therapy aimed at treating and preventing malaria episodes among pregnant women and young children is one public health measure in endemic countries. Since the 1980s, the growing field of population health has broadened the focus of public health from individual behaviors and risk factors to population-level issues such as inequality , poverty, and education. Modern public health

1188-500: A particular group (for example, by citizenship, or membership within an organization such as health insurance group). This approach prioritizes simplification of the triage and transparency, although there are significant ethical drawbacks, especially when procedures favor those who are part of socioeconomically advantaged groups (such as those with health insurance). Procedural systems of triage emphasize certain patterns of decision making based on preferred procedures. This can take place in

1287-407: A review of research on what local authorities can do to tackle obesity. The review covers interventions in the food environment (what people buy and eat), the built and natural environments , schools, and the community, as well as those focussing on active travel , leisure services and public sports, weight management programmes , and system-wide approaches . Health inequalities, driven by

1386-509: A series of publications on this topic in the late 1980s and early 1990s criticizing the UK's the Health of The Nation campaign. These publications exposed abuse of epidemiology and statistics by the public health movement to support lifestyle interventions and screening programs. A combination of inculcating a fear of ill-health and a strong notion of individual responsibility has been criticized as

1485-496: A significant increase after World War II as concerns over the spread of disease as a result of globalization increased and the HIV/AIDS epidemic in sub-Saharan Africa surfaced. From 1990 to 2010, total health aid from developed countries increased from 5.5 billion to 26.87 billion with wealthy countries continuously donating billions of dollars every year with the goal of improving population health. Some efforts, however, receive

1584-475: A significantly larger proportion of funds such as HIV which received an increase in funds of over $ 6 billion between 2000 and 2010 which was more than twice the increase seen in any other sector during those years. Health aid has seen an expansion through multiple channels including private philanthropy, non-governmental organizations , private foundations such as the Rockefeller Foundation or

1683-433: A specialized database, Disaster Lit: Database for Disaster Medicine and Public Health, an open access resource of disaster medicine documents, including guidelines, research reports, conference proceedings, fact sheets, training, fact sheets, and similar materials. The Disaster Medicine practitioner must be well-versed in the ethical dilemmas that commonly arise in disaster settings. One of the most common dilemmas occurs when

1782-531: Is a fundamental part of population health. Scholars such as Coggon and Pielke express concerns about bringing general issues of wealth distribution into population health. Pielke worries about "stealth issue advocacy" in population health. Jung, Boris and Lushniak consider population health to be a concept that is the goal of an activity called public health practiced through the specialty preventive medicine. Lifestyle medicine uses individual lifestyle modification to prevent or revert disease and can be considered

1881-630: Is a recent well-known disaster situation and has made a big impact on the preparedness work. But hospital disaster preparation is at least described in the Second World War. Some hospitals, such as San Francisco General Hospital , have medical surge exercises to train staff. In February 2019, the American Hospital Association released a report that medical surge capacity was one of four major challenges threatening rural hospitals' ability to provide care, along with

1980-512: Is achieved might differ. The guiding factor is need rather than the ultimate benefit or utility of the intervention. Approaches based on egalitarian principles are complex guides in disaster settings. In the words of Eyal (2016) "Depending on the exact variant of egalitarianism, the resulting limited priority may go to patients whose contemporaneous prognosis is dire (because their medical prospects are now poor), to patients who have lived with serious disabilities for years (because their lifetime health

2079-409: Is dealing with the conflict between individual rights and maximizing right to health . Public health is justified by consequentialist utilitarian ideas, but is constrained and critiqued by liberal , deontological , principlist and libertarian philosophies Stephen Holland argues that it can be easy to find a particular framework to justify any viewpoint on public health issues, but that

2178-451: Is due to the activation of an evolved reward system for substances such as drugs, tobacco, alcohol , refined salt , fat , and carbohydrates . New technologies such as modern transportation also cause reduced physical activity . Research has found that behavior is more effectively changed by taking evolutionary motivations into consideration instead of only presenting information about health effects. The marketing industry has long known

2277-598: Is formed by the American Academy of Medical Administrators (AAMA) to provide certification and scholarly study in the area of medical contingency planning and healthcare disaster planning. 2001 – The September 11, 2001 attacks on the World Trade Center and the Pentagon cause the largest loss of life resulting from an attack on American targets on United States soil since Pearl Harbor. As a result,

2376-465: Is limited. Public health programs providing vaccinations have made major progress in promoting health, including substantially reducing the occurrence of cholera and polio and eradicating smallpox , diseases that have plagued humanity for thousands of years. The World Health Organization (WHO) identifies core functions of public health programs including: In particular, public health surveillance programs can: The "Truth" campaign, launched by

2475-434: Is often concerned with addressing determinants of health across a population. There is a recognition that health is affected by many factors including class, race, income, educational status, region of residence, and social relationships ; these are known as " social determinants of health ". The upstream drivers such as environment, education, employment, income, food security, housing, social inclusion and many others effect

2574-584: Is one of Europe's most labor-intensive industries. In late 2020, it accounted for more than 21 million employment in the European Union when combined with social work. According to the WHO , several countries began the COVID-19 pandemic with insufficient health and care professionals, inappropriate skill mixtures, and unequal geographical distributions. These issues were worsened by the pandemic, reiterating

2673-530: Is part of a country's overall healthcare system. Public health is implemented through the surveillance of cases and health indicators , and through the promotion of healthy behaviors . Common public health initiatives include promotion of hand-washing and breastfeeding , delivery of vaccinations , promoting ventilation and improved air quality both indoors and outdoors , suicide prevention , smoking cessation , obesity education , increasing healthcare accessibility and distribution of condoms to control

2772-487: Is poor maternal and child health, exacerbated by malnutrition and poverty. The WHO reports that a lack of exclusive breastfeeding during the first six months of life contributes to over a million avoidable child deaths each year. Public health surveillance has led to the identification and prioritization of many public health issues facing the world today, including HIV/AIDS , diabetes , waterborne diseases , zoonotic diseases , and antibiotic resistance leading to

2871-522: Is related to public health. The American Board of Preventive Medicine separates three categories of preventive medicine: aerospace health, occupational health , and public health and general preventative medicine. Jung, Boris and Lushniak argue that preventive medicine should be considered the medical specialty for public health but note that the American College of Preventive Medicine and American Board of Preventive Medicine do not prominently use

2970-872: Is the basis for public health. The public can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of health takes into account physical, psychological , and social well-being , among other factors. Public health is an interdisciplinary field. For example, epidemiology , biostatistics , social sciences and management of health services are all relevant. Other important sub-fields include environmental health , community health , behavioral health , health economics , public policy , mental health , health education , health politics , occupational safety , disability , oral health , gender issues in health, and sexual and reproductive health . Public health, together with primary care , secondary care, and tertiary care ,

3069-540: Is the control of tobacco smoking . Many nations have implemented major initiatives to cut smoking, such as increased taxation and bans on smoking in some or all public places. Supporters argue by presenting evidence that smoking is one of the major killers, and that therefore governments have a duty to reduce the death rate, both through limiting passive (second-hand) smoking and by providing fewer opportunities for people to smoke. Opponents say that this undermines individual freedom and personal responsibility, and worry that

Disaster response is the third phase of the disaster life cycle. Medical contingency planning – The act of devising a methodology for meeting the medical requirements of a population affected by a disaster event. Medical surge – An influx of patients (physical casualties and psychological casualties), bystanders, visitors, family members, media and individuals searching for

3267-1515: Is to improve the health of individuals and populations, and to increase life expectancy . Public health is a complex term, composed of many elements and different practices. It is a multi-faceted, interdisciplinary field. For example, epidemiology , biostatistics , social sciences and management of health services are all relevant. Other important sub-fields include environmental health , community health , behavioral health , health economics , public policy , mental health , health education , health politics , occupational safety , disability , gender issues in health, and sexual and reproductive health . Modern public health practice requires multidisciplinary teams of public health workers and professionals. Teams might include epidemiologists , biostatisticians , physician assistants , public health nurses , midwives , medical microbiologists , pharmacists , economists , sociologists , geneticists , data managers , environmental health officers ( public health inspectors ), bioethicists , gender experts, sexual and reproductive health specialists, physicians , and veterinarians . The elements and priorities of public health have evolved over time, and are continuing to evolve. Common public health initiatives include promotion of hand-washing and breastfeeding , delivery of vaccinations , suicide prevention , smoking cessation , obesity education , increasing healthcare accessibility and distribution of condoms to control

Procedural Approach The inherent difficulties in triage may lead practitioners to attempt to minimize active selection or prioritization of patients in face of scarcity of resources, and instead rely upon guidelines which do not take into account medical need or possibility of positive outcomes. In this approach, known as proceduralism, selection or prioritization may be based on patient's inclusion in

3465-514: The Bill & Melinda Gates Foundation , bilateral donors, and multilateral donors such as the World Bank or UNICEF . The result has been a sharp rise in uncoordinated and fragmented funding of an ever-increasing number of initiatives and projects. To promote better strategic cooperation and coordination between partners, particularly among bilateral development agencies and funding organizations,

3564-530: The Institute for Health Metrics and Evaluation and the World Health Organization has shown a link between international health aid in developing countries and a reduction in adult mortality rates. However, a 2014–2016 study suggests that a potential confounding variable for this outcome is the possibility that aid was directed at countries once they were already on track for improvement. That same study, however, also suggests that 1 billion dollars in health aid

3663-613: The NIMS Implementation Plan for Hospitals and Healthcare Facilities . Disaster healthcare – The provision of healthcare services by healthcare professionals to disaster survivors and disaster responders both in a disaster impact area and healthcare evacuation receiving facilities throughout the disaster life cycle. Disaster behavioral health – Disaster behavioral health deals with the capability of disaster responders to perform optimally, and for disaster survivors to maintain or rapidly restore function, when faced with

ESSENCE brings together a wide range of funding agencies to coordinate funding efforts. In 2009 health aid from the OECD amounted to $ 12.47 billion which amounted to 11.4% of its total bilateral aid. In 2009, Multilateral donors were found to spend 15.3% of their total aid on bettering public healthcare. Debates exist questioning

The requirements of surge may extend beyond direct patient care to include such tasks as extensive laboratory studies or epidemiological investigations. This is related to patients volume and identifying numbers of hospital beds, personnel, supplies, and equipment should be identified and addressed." These factors are often described as

4158-599: The American Legacy Foundation in 2000. This campaign aimed to educate and discourage young people from smoking by exposing the tobacco industry's deceptive practices. Through a combination of powerful visuals, persuasive storytelling, and relatable messaging, the "Truth" campaign successfully reduced smoking rates among teenagers and young adults. Many health problems are due to maladaptive personal behaviors. From an evolutionary psychology perspective, over consumption of novel substances that are harmful

4257-409: The United States as early as the 1980s, it was not until 2003 that the medical community embraced the need for the new specialty. Throughout this period, incomplete and faltering medical responses to disaster events made it increasingly apparent in the United States of America that federal, state and local emergency management organizations were in need of a mechanism to identify qualified physicians in

4356-807: The United States of America for the purpose of scholarly exchange and education in Disaster Medicine as well as the development of an examination demonstrating excellence towards board certification in this new specialty. In 2008, the United States National Library of Medicine (NLM) formed the Disaster Information Management Research Center (DIMRC) in support of the NLM's history of supporting healthcare professionals and information workers in accessing health information. DIMRC provides

4455-452: The age of five were overweight in 2014. Once considered a problem in high-income countries, it is now on the rise in low-income countries, especially in urban settings. Many public health programs are increasingly dedicating attention and resources to the issue of obesity, with objectives to address the underlying causes including healthy diet and physical exercise . The National Institute for Health and Care Research (NIHR) has published

4554-406: The aggregate medical need exceeds the ability to provide a normal standard of care for all patients. Triage In the event of a future pandemic, the number of patients that require additional respiratory support will outnumber the number of available ventilators. Although a hypothetical example, similar natural disasters have occurred in the past. Historically, the influenza pandemic of 1918-19 and

4653-405: The authors opined that "The fact that type 2 diabetes, a largely preventable disorder, has reached epidemic proportion is a public health humiliation." The risk of type 2 diabetes is closely linked with the growing problem of obesity . The WHO's latest estimates as of June 2016 highlighted that globally approximately 1.9 billion adults were overweight in 2014, and 41 million children under

4752-422: The beginnings of human civilization , communities promoted health and fought disease at the population level. In complex , pre-industrialized societies , interventions designed to reduce health risks could be the initiative of different stakeholders, such as army generals, the clergy or rulers. Great Britain became a leader in the development of public health initiatives, beginning in the 19th century, due to

4851-458: The burden of disease and inequality faced by developing countries and lead to a healthier future. The links between the various sustainable development goals and public health are numerous and well established. Surge capacity A medical surge occurs when "patient volumes challenge or exceed a hospital's servicing capacity"—often but not always tied to high volume of patients in a hospital's emergency room . Medical surges can occur after

4950-458: The correct approach is to find a framework that best describes a situation and see what it implies about public health policy. The definition of health is vague and there are many conceptualizations. Public health practitioners definition of health can different markedly from members of the public or clinicians . This can mean that members of the public view the values behind public health interventions as alien which can cause resentment amongst

5049-489: The dead and heal the living." 1812 – Napoleonic wars give rise to the military medical practice of triage in an effort to sort wounded soldiers in those to receive medical treatment and return to battle and those whose injuries are non-survivable. Dominique-Jean Larrey , a surgeon in the French emperor's army, not only conceives of taking care of the wounded on the battlefield, but creates the concept of ambulances, collecting

5148-663: The development and modification of public and private policy, legislation, disaster planning and disaster recovery. Within the United States of America, the specialty of disaster medicine fulfills the requirements set for by Homeland Security Presidential Directives (HSPD), the National Response Plan (NRP), the National Incident Management System (NIMS), the National Resource Typing System (NRTS) and

5247-424: The development of such triaging protocols are often based on the principles of the theories of utilitarianism , egalitarianism and proceduralism. Utilitarian Approach The Utilitarian theory works on the premise that the responder shall 'maximise collective welfare'; or in other words, 'do the greatest good for the greatest numbers of people'. The utilitarian will necessarily need a measure by which to assess

5346-442: The disaster event and the disaster response and culminating in the disaster recovery. Interphase begins as the end of the last disaster recovery and ends at the onset of the next disaster event. The disaster event begins when the event occurs and ends when the immediate event subsides. The disaster response begins when the event occurs and ends when acute disaster response services are no longer needed. Disaster recovery also begins with

5445-432: The disaster response and continues until the affected area is returned to the pre-event condition. Disaster planning – The act of devising a methodology for dealing with a disaster event, especially one with the potential to occur suddenly and cause great injury and/or loss of life, damage and hardship. Disaster planning occurs during the disaster interphase. Disaster preparation – The act of practicing and implementing

5544-419: The distribution of health between and within populations and are often shaped by policy. A social gradient in health runs through society. The poorest generally have the worst health, but even the middle classes will generally have worse health outcomes than those of a higher social level. The new public health advocates for population-based policies that improve health in an equitable manner. The health sector

5643-404: The effects of chronic diseases as life expectancy increases, the poorer communities being heavily affected by both chronic and infectious diseases. Another major public health concern in the developing world is poor maternal and child health, exacerbated by malnutrition and poverty. The WHO reports that a lack of exclusive breastfeeding during the first six months of life contributes to over

5742-422: The efficacy of international health aid. Supporters of aid claim that health aid from wealthy countries is necessary in order for developing countries to escape the poverty trap . Opponents of health aid claim that international health aid actually disrupts developing countries' course of development, causes dependence on aid, and in many cases the aid fails to reach its recipients. For example, recently, health aid

5841-486: The face of a global upturn in the rate of disasters. Many physicians who volunteer at disasters have a bare minimum of knowledge in disaster medicine and often pose a hazard to themselves and the response effort because they have little or no field response training. It was against this backdrop that the American Academy of Disaster Medicine (AADM) and the American Board of Disaster Medicine (ABODM) were formed in

5940-760: The fact that it was the first modern urban nation worldwide. The public health initiatives that began to emerge initially focused on sanitation (for example, the Liverpool and London sewerage systems ), control of infectious diseases (including vaccination and quarantine ) and an evolving infrastructure of various sciences, e.g. statistics, microbiology, epidemiology, sciences of engineering. Public health has been defined as "the science and art of preventing disease ", prolonging life and improving quality of life through organized efforts and informed choices of society , organizations (public and private), communities and individuals . The public can be as small as

This is not outcome driven; it is a process driven activity aimed at providing consistent frameworks upon which to base decisions. These are by no means the only systems upon which decisions are made, but provide a basic framework to evaluate the ethical reasoning behind what are often difficult choices during disaster response and management. Internationally, disaster medicine specialists must demonstrate competency in areas of disaster healthcare and emergency management including but not limited to: 1755 - 1755 Lisbon Earthquake "What now?

6336-448: The harmful and undesirable effects of tobacco smoking on other persons and imposing smoking bans in public places have been particularly effective in reducing tobacco smoking. Public libraries can also be beneficial tools for public health changes. They provide access to healthcare information, link people to healthcare services, and even can provide direct care in certain situations. As well as seeking to improve population health through

6435-796: The highest possible level of health". The WHO's broad mandate includes advocating for universal healthcare, monitoring public health risks, coordinating responses to health emergencies, and promoting human health and well-being. The WHO has played a leading role in several public health achievements, most notably the eradication of smallpox , the near- eradication of polio , and the development of an Ebola vaccine . Its current priorities include communicable diseases , particularly HIV/AIDS , Ebola , COVID-19 , malaria and tuberculosis ; non-communicable diseases such as heart disease and cancer; healthy diet , nutrition, and food security ; occupational health ; and substance abuse . Most countries have their own governmental public health agency, often called

6534-446: The implementation of specific population-level interventions, public health contributes to medical care by identifying and assessing population needs for health care services, including: Some programs and policies associated with public health promotion and prevention can be controversial. One such example is programs focusing on the prevention of HIV transmission through safe sex campaigns and needle-exchange programs . Another

6633-495: The importance of associating products with high status and attractiveness to others. Films are increasingly being recognized as a public health tool, with the Harvard University 's T.H. Chan School of Public Health categorizing such films as "impact filmmaking." In fact, film festivals and competitions have been established to specifically promote films about health. Conversely, it has been argued that emphasizing

6732-441: The importance of public health programs in reducing the incidence of disease, disability, and the effects of aging and other physical and mental health conditions. However, public health generally receives significantly less government funding compared with medicine. Although the collaboration of local health and government agencies is considered best practice to improve public health, the pieces of evidence available to support this

6831-477: The importance of public health. In the United States, a history of underinvestment in public health undermined the public health workforce and support for population health, long before the pandemic added to stress, mental distress, job dissatisfaction, and accelerated departures among public health workers. Health aid to developing countries is an important source of public health funding for many developing countries. Health aid to developing countries has shown

6930-944: The ministry of health, with responsibility for domestic health issues. For example, in the United States , state and local health departments are on the front line of public health initiatives. In addition to their national duties, the United States Public Health Service (PHS), led by the Surgeon General of the United States Public Health Service , and the Centers for Disease Control and Prevention , headquartered in Atlanta , are also involved with international health activities. Most governments recognize

7029-500: The missing who present to a hospital or healthcare facility for treatment, information and/or shelter as a result of a disaster. Surge capacity – The ability to manage a sudden, unexpected increase in patient volume that would otherwise severely challenge or exceed the current capacity of the health care system. Medical triage – The separation of patients based on severity of injury or illness in light of available resources. Psychosocial triage – The separation of patients based on

7128-488: The more recent SARS epidemic in 2003 led to resource scarcity and necessitated triage. One paper estimated that in the United States, the need for ventilators would be double the number available in the setting of an influenza pandemic similar to the scale of 1918. In other countries with fewer resources, shortages are postulated to be even more severe. How, then, is a clinician to decide whom to offer this treatment? Examples of common approaches that guide triage include "saving

7227-511: The most lives", calling for care to be provided to "the sickest first" or alternatively a "first come, first served" approach may attempt to sidestep the difficult decision of triage. Emergency services often use their own triaging systems to be able to work through some of these challenging situations; however, these guidelines often assume no resource scarcity, and therefore, different triaging systems must be developed for resource-limited, disaster response settings. Useful ethical approaches to guide

7326-593: The need for disaster medicine is galvanized. 2001 – On October 29, 2001, President George W. Bush issues Homeland Security Presidential Directive 1 (HSPD-1), establishing the organization and operation of the Homeland Security Council . 2002 – On March 11, 2002, President Bush issues HSPD-3, establishing the Homeland Security Advisory System . 2002 – On December 11, 2002, President Bush issues HSPD-4, outlining

7425-539: The needs of the normative group. Identifying bias within public health research and practice is essential to ensuring public health efforts mitigate and don't aggravate health inequities. The World Health Organization (WHO) is a specialized agency of the United Nations responsible for international public health. The WHO Constitution, which establishes the agency's governing structure and principles, states its main objective as "the attainment by all peoples of

7524-576: The outcome of the intervention. This could be thought of through various ways, for instance: the number of lives saved, or the number of years of life saved through the intervention. Thus, the utilitarian would prioritize saving the youngest of the patients over the elderly or those who are more likely to die despite an intervention, in order to 'maximise the collective years of life saved'. Commonly used metrics to quantify utility of health interventions include DALYs (Disability Adjusted Life Years) and QALYs (Quality Adjusted Life Years) which take into account
