Preventive healthcare, or prophylaxis, is the application of healthcare measures to prevent .Hugh R. Leavell and E. Gurney Clark as "the science and art of preventing disease, prolonging life, and promoting physical and mental health and efficiency. Leavell, H. R., & Clark, E. G. (1979). Preventive Medicine for the Doctor in his Community (3rd ed.). Huntington, NY: Robert E. Krieger Publishing Company. Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes that begin before individuals realize they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal, primary, secondary, and tertiary prevention.
Each year, millions of people die of preventable causes. A 2004 study showed that about half of all deaths in the United States in 2000 were due to preventable behaviors and exposures. Leading causes included cardiovascular disease, chronic respiratory disease, unintentional injuries, diabetes, and certain infectious diseases. This same study estimates that 400,000 people die each year in the United States due to poor diet and a sedentary lifestyle. According to estimates made by the World Health Organization (WHO), about 55 million people died worldwide in 2011, and two-thirds of these died from non-communicable diseases, including cancer, diabetes, and chronic cardiovascular and lung diseases. This is an increase from the year 2000, during which 60% of deaths were attributed to these diseases.)
Preventive healthcare is especially important given the worldwide rise in the prevalence of chronic diseases and deaths from these diseases. There are many methods for prevention of disease. One of them is prevention of teenage smoking through information giving.LeChelle Saunders, BSc: Smoking is Critical to Our Health. Be Smart, Don't Start It is recommended that adults and children aim to visit their doctor for regular check-ups, even if they feel healthy, to perform disease screening, identify risk factors for disease, discuss tips for a healthy and balanced lifestyle, stay up to date with immunizations and boosters, and maintain a good relationship with a healthcare provider. In pediatrics, some common examples of primary prevention are encouraging parents to turn down the temperature of their home water heater in order to avoid scalding burns, encouraging children to wear bicycle helmets, and suggesting that people use the air quality index (AQI) to check the level of pollution in the outside air before engaging in sporting activities.
Some common disease screenings include checking for hypertension (high blood pressure), hyperglycemia (high blood sugar, a risk factor for diabetes mellitus), hypercholesterolemia (high blood cholesterol), screening for colon cancer, depression, HIV and other common types of sexually transmitted disease such as chlamydia, syphilis, and gonorrhea, mammography (to screen for breast cancer), colorectal cancer screening, a Pap test (to check for cervical cancer), and screening for osteoporosis. Genetic testing can also be performed to screen for mutations that cause or predisposition to certain diseases such as breast or ovarian cancer. However, these measures are not affordable for every individual and the cost effectiveness of preventive healthcare is still a topic of debate.
Primal and primordial prevention | Primal prevention has been propounded as a separate category of health promotion based on the evidence that epigenetic processes start at conception (see below: Primal and primordial preventions). Primordial prevention refers to measures designed to avoid the development of risk factors in the first place, early in life. |
Primary prevention | Methods to avoid occurrence of disease either through eliminating disease agents or increasing resistance to disease.Katz, D., & Ather, A. (2009). Preventive Medicine, Integrative Medicine & The Health of The Public. Commissioned for the IOM Summit on Integrative Medicine and the Health of the Public. Retrieved from Examples include immunization against disease, maintaining a healthy diet and exercise regimen, and avoiding smoking. |
Secondary prevention | Methods to detect and address an existing disease prior to the appearance of symptoms. Examples include treatment of hypertension (a risk factor for many cardiovascular diseases), and cancer screenings. |
Tertiary prevention | Methods to reduce the harm of symptomatic disease, such as disability or death, through rehabilitation and treatment. Examples include surgical procedures that halt the spread or progression of disease. |
Quaternary prevention | Methods to mitigate or avoid results of unnecessary or excessive interventions in the health system, including potential violations of rights.Gofrit ON, Shemer J, Leibovici D, Modan B, Shapira SC. Quaternary prevention: a new look at an old challenge. Isr Med Assoc J. 2000;2(7):498-500. |
Primordial prevention refers to all measures designed to prevent the development of risk factors in the first place, early in life, and even preconception, as Ruth A. Etzel has described it "all population-level actions and measures that inhibit the emergence and establishment of adverse environmental, economic, and social conditions". This could be reducing air pollution or prohibiting endocrine-disrupting chemicals in food-handling equipment and food contact materials.
Scientific advancements in genetics have contributed to the knowledge of hereditary diseases and have facilitated progress in specific protective measures in individuals who are carriers of a disease gene or have an increased predisposition to a specific disease. Genetic testing has allowed physicians to make quicker and more accurate diagnoses and has allowed for tailored treatments or personalized medicine.
Food safety has a significant impact on human health and food quality monitoring has increased. Water, including drinking water, Water quality in many cases for securing health. There also is some monitoring of air pollution. In many cases, environmental standards such as via maximum pollution levels, regulation of chemicals, occupational hygiene requirements or consumer protection regulations establish some protection in combination with the monitoring.
Preventive measures like and medical screenings are also important. Using PPE properly and getting the recommended vaccines and screenings can help decrease the spread of respiratory diseases, protecting the healthcare workers as well as their patients.
The general use of machinery that has adequate ventilation and airflow is suggested for these patients in order to halt progression and complications of disease. A study conducted in nursing homes to prevent diseases concluded that the use of evaporative humidifiers to maintain the indoor humidity within the range 40–60% can reduce respiratory risk. Certain diseases thrive in different humidities, so the use of the humidifiers can help kill the particles of diseases.

However, several of the leading causes of death – or underlying contributors to earlier death – may not be included as "preventable" causes of death. A study concluded that pollution was "responsible for approximately 9 million deaths per year" in 2019. And another study concluded that the global mean loss of life expectancy (a measure similar to years of potential life lost) from air pollution in 2015 was 2.9 years, substantially more than, for example, 0.3 years from all forms of direct violence, albeit a significant fraction of the LLE is considered to be unavoidable (such as pollution from some natural wildfires).
A landmark study conducted by the World Health Organization and the International Labour Organization found that exposure to long working hours is the occupational risk factor with the largest attributable burden of disease, i.e. an estimated 745,000 fatalities from ischemic heart disease and stroke events in 2016. With this study, prevention of exposure to long working hours has emerged as a priority for prevention healthcare in workplace settings.
Child mortality is caused by factors including poverty, environmental hazards, and lack of maternal education. In 2003, the World Health Organization created a list of interventions in the following table that were judged economically and operationally "feasible," based on the healthcare resources and infrastructure in 42 nations that contribute to 90% of all infant and child deaths. The table indicates how many infant and child deaths could have been prevented in 2000, assuming universal healthcare coverage.

Prevention of tobacco use is paramount to prevention of lung cancer. Individual, community, and statewide interventions can prevent or cease tobacco use. 90% of adults in the U.S. who have ever smoked did so prior to the age of 20. In-school prevention/educational programs, as well as counseling resources, can help prevent and cease adolescent smoking. Other cessation techniques include group support programs, nicotine replacement therapy (NRT), hypnosis, and self-motivated behavioral change. Studies have shown long term success rates (>1 year) of 20% for hypnosis and 10%-20% for group therapy.
Cancer screening programs serve as effective sources of secondary prevention. The Mayo Clinic, Johns Hopkins, and Memorial Sloan-Kettering hospitals conducted annual x-ray screenings and sputum cytology tests and found that lung cancer was detected at higher rates, earlier stages, and had more favorable treatment outcomes, which supports widespread investment in such programs.
Legislation can also affect smoking prevention and cessation. In 1992, Massachusetts (United States) voters passed a bill adding an extra 25 cent tax to each pack of cigarettes, despite intense lobbying and $7.3 million spent by the tobacco industry to oppose this bill. Tax revenue goes toward tobacco education and control programs and has led to a decline of tobacco use in the state.
Lung cancer and tobacco smoking are increasing worldwide, especially in China. China is responsible for about one-third of the global consumption and production of tobacco products. Tobacco control policies have been ineffective as China is home to 350 million regular smokers and 750 million passive smokers and the annual death toll is over 1 million. Recommended actions to reduce tobacco use include decreasing tobacco supply, increasing tobacco taxes, widespread educational campaigns, decreasing advertising from the tobacco industry, and increasing tobacco cessation support resources. In Wuhan, China, a 1998 school-based program implemented an anti-tobacco curriculum for adolescents and reduced the number of regular smokers, though it did not significantly decrease the number of adolescents who initiated smoking. This program was therefore effective in secondary but not primary prevention and shows that school-based programs have the potential to reduce tobacco use.
The Centers for Disease Control and Prevention (CDC) recommends several primary prevention methods including: limiting sun exposure between 10 AM and 4 PM, when the sun is strongest, wearing tighter-weave natural cotton clothing, wide-brim hats, and sunglasses as protective covers, using sunscreens that protect against both UV-A and UV-B rays, and avoiding tanning salons. Sunscreen should be reapplied after sweating, exposure to water (through swimming for example) or after several hours of sun exposure. Since skin cancer is very preventable, the CDC recommends school-level prevention programs including preventive curricula, family involvement, participation and support from the school's health services, and partnership with community, state, and national agencies and organizations to keep children away from excessive UV radiation exposure.
Most skin cancer and sun protection data comes from Australia and the United States. An international study reported that Australians tended to demonstrate higher knowledge of sun protection and skin cancer knowledge, compared to other countries. Of children, adolescents, and adults, sunscreen was the most commonly used skin protection. However, many adolescents purposely used sunscreen with a low sun protection factor (SPF) in order to get a tan. Various Australian studies have shown that many adults failed to use sunscreen correctly; many applied sunscreen well after their initial sun exposure and/or failed to reapply when necessary. A 2002 case-control study in Brazil showed that only 3% of case participants and 11% of control participants used sunscreen with SPF >15.
In developing nations in Latin America, such as Chile, Colombia, Costa Rica, and Cuba, both public and privately organized programs have offered women routine cytological screening since the 1970s. However, these efforts have not resulted in a significant change in cervical cancer incidence or mortality in these nations. This is likely due to low quality, inefficient testing. However, Puerto Rico, which has offered early screening since the 1960s, has witnessed almost a 50% decline in cervical cancer incidence and almost a four-fold decrease in mortality between 1950 and 1990. Brazil, Peru, India, and several high-risk nations in sub-Saharan Africa which lack organized screening programs, have a high incidence of cervical cancer.
It is also highly preventable; about 80 percent of colorectal cancers begin as adenoma, commonly called colorectal polyp, which can be easily detected and removed during a colonoscopy. Other methods of screening for polyps and cancers include fecal occult blood testing. Lifestyle changes that may reduce the risk of colorectal cancer include increasing consumption of whole grains, fruits and vegetables, and reducing consumption of red meat.
These sorts of disparities and barriers exist worldwide as well. Often, there are decades of gaps in life expectancy between developing and developed countries. For example, Japan has an average life expectancy that is 36 years greater than that in Malawi. Low-income countries also tend to have fewer physicians than high-income countries. In Nigeria and Myanmar, there are fewer than 4 physicians per 100,000 people while Norway and Switzerland have a ratio that is ten-fold higher. Common barriers worldwide include lack of availability of health services and healthcare providers in the region, great physical distance between the home and health service facilities, high transportation costs, high treatment costs, and social norms and stigma toward accessing certain health services.
Developing future economic models that would guide both private and public investments as well as drive future policy to evaluate the efficacy of positive lifestyle choices on health is a major topic for economists globally. Americans spend over three trillion a year on health care but have a higher rate of infant mortality, shorter Life expectancy, and a higher rate of diabetes than other high-income nations because of negative lifestyle choices. Despite these large costs, very little is spent on prevention for lifestyle-caused conditions in comparison. In 2016, the Journal of the American Medical Association estimated that $101 billion was spent in 2013 on the preventable disease of diabetes, and another $88 billion was spent on heart disease. In an effort to encourage healthy lifestyle choices, as of 2010 workplace wellness programs were on the rise but the economics and effectiveness data were continuing to evolve and develop.
Health insurance coverage impacts lifestyle choices, even intermittent loss of coverage had negative effects on healthy choices in the U.S. The repeal of the Affordable Care Act (ACA) could significantly impact coverage for many Americans as well as "The Prevention and Public Health Fund" which is the U.S. first and only mandatory funding stream dedicated to improving public health including counseling on lifestyle prevention issues, such as weight management, alcohol use, and treatment for depression.
Because in the U.S. chronic illnesses predominate as a cause of death and pathways for treating chronic illnesses are complex and multifaceted, prevention is a best practice approach to chronic disease when possible. In many cases, prevention requires mapping complex pathways to determine the ideal point for intervention. Cost-effectiveness of prevention is achievable, but impacted by the length of time it takes to see effects/outcomes of intervention. This makes prevention efforts difficult to fund—particularly in strained financial contexts. Prevention potentially creates other costs as well, due to Life extension the Life expectancy and thereby increasing opportunities for illness. In order to assess the cost-effectiveness of prevention, the cost of the preventive measure, savings from avoiding morbidity, and the cost from extending the lifespan need to be considered. Life extension costs become smaller when accounting for savings from postponing the last year of life, which makes up a large fraction of lifetime medical expenditures and becomes cheaper with age. Prevention leads to savings only if the cost of the preventive measure is less than the savings from avoiding morbidity net of the cost of extending the life span. In order to establish reliable economics of prevention for illnesses that are complicated in origin, knowing how best to assess prevention efforts, i.e. developing useful measures and appropriate scope, is required.
A 2010 study reported that in the United States, vaccinating children, cessation of smoking, daily prophylactic use of aspirin, and screening of breast and colorectal cancers had the most potential to prevent premature death. Preventive health measures that resulted in savings included vaccinating children and adults, smoking cessation, daily use of aspirin, and screening for issues with alcoholism, obesity, and vision failure. These authors estimated that if usage of these services in the United States increased to 90% of the population, there would be net savings of $3.7 billion, which comprised only about -0.2% of the total 2006 United States healthcare expenditure. Despite the potential for decreasing healthcare spending, utilization of healthcare resources in the United States still remains low, especially among Latinos and African-Americans. Overall, preventive services are difficult to implement because healthcare providers have limited time with patients and must integrate a variety of preventive health measures from different sources.
While these specific services bring about small net savings, not every preventive health measure saves more than it costs. A 1970s study showed that preventing heart attacks by treating hypertension early on with drugs actually did not save money in the long run. The money saved by evading treatment from heart attack and stroke only amounted to about a quarter of the cost of the drugs.Weinstein MC, Stason WB. "Hypertension: a policy perspective. Cambridge, Mass.: Harvard University Press, 1976. Similarly, it was found that the cost of drugs or dietary changes to decrease high blood cholesterol exceeded the cost of subsequent heart disease treatment. Taylor WC, Pass TM, Shepard DS, Komaroff AL. Cost effectiveness of cholesterol reduction for the primary prevention of coronary heart disease in men. In: Goldbloom RB, Lawrence RS, eds. Preventing disease: beyond the rhetoric. New York: Springer-Verlag, 1990:437-41. Due to these findings, some argue that rather than focusing healthcare reform efforts exclusively on preventive care, the interventions that bring about the highest level of health should be prioritized.
In 2008, Cohen et al. outlined a few arguments made by skeptics of preventive healthcare. Many argue that preventive measures only cost less than future treatment when the proportion of the population that would become ill in the absence of prevention is fairly large. The Diabetes Prevention Program Research Group conducted a 2012 study evaluating the costs and benefits in quality-adjusted life-years or of lifestyle changes versus taking the drug metformin. They found that neither method brought about financial savings, but were cost-effective nonetheless because they brought about an increase in QALYs. In addition to scrutinizing costs, preventive healthcare skeptics also examine efficiency of interventions. They argue that while many treatments of existing diseases involve use of advanced equipment and technology, in some cases, this is a more efficient use of resources than attempts to prevent the disease. Cohen suggested that the preventive measures most worth exploring and investing in are those that could benefit a large portion of the population to bring about cumulative and widespread health benefits at a reasonable cost.
Gortmaker, S.L. et al. (2015) states: "The four initial interventions were selected by the investigators to represent a broad range of nationally scalable strategies to reduce childhood obesity using a mix of both policy and programmatic strategies... 1. an excise tax of $0.01 per ounce of sweetened beverages, applied nationally and administered at the state level (SSB), 2. elimination of the tax deductibility of advertising costs of TV advertisements for "nutritionally poor" foods and beverages seen by children and adolescents (TV AD), 3. state policy requiring all public elementary schools in which physical education (PE) is currently provided to devote ≥50% of PE class time to moderate and vigorous physical activity (Active PE), and 4. state policy to make early child educational settings healthier by increasing physical activity, improving nutrition, and reducing screen time (ECE)." The CHOICES found that SSB, TV AD, and ECE led to net cost savings. Both SSB and TV AD increased quality adjusted life years and produced yearly tax revenue of 12.5 billion U.S. dollars and 80 million U.S. dollars, respectively.
Some challenges with evaluating the effectiveness of child obesity interventions include:
Preventive care transcends demographics and is applicable to people of every age. The Health Capital Theory underpins the importance of preventive care across the lifecycle and provides a framework for understanding the variances in health and health care that are experienced. It treats health as a stock that provides direct utility. Health depreciates with age and the aging process can be countered through health investments. The theory further supports that individuals demand good health, that the demand for health investment is a derived demand (i.e. investment is health is due to the underlying demand for good health), and the efficiency of the health investment process increases with knowledge (i.e. it is assumed that the more educated are more efficient consumers and producers of health).
The prevalence elasticity of demand for prevention can also provide insights into the economics. Demand for preventive care can alter the prevalence rate of a given disease and further reduce or even reverse any further growth of prevalence. Reduction in prevalence subsequently leads to reduction in costs. There are a number of organizations and policy actions that are relevant when discussing the economics of preventive care services. The evidence base, viewpoints, and policy briefs from the Robert Wood Johnson Foundation, the Organisation for Economic Co-operation and Development (OECD), and efforts by the U.S. Preventive Services Task Force (USPSTF) all provide examples that improve the health and well-being of populations (e.g. preventive health assessments/screenings, prenatal care, and telehealth/telemedicine). The Affordable Care Act (ACA) has major influence on the provision of preventive care services, although it is currently under heavy scrutiny and review by the new administration. According to the Centers for Disease Control and Prevention (CDC), the ACA makes preventive care affordable and accessible through mandatory coverage of preventive services without a deductible, copayment, coinsurance, or other cost sharing.
The U.S. Preventive Services Task Force (USPSTF), a panel of national experts in prevention and evidence-based medicine, works to improve health of Americans by making evidence-based recommendations about clinical preventive services. They do not consider the cost of a preventive service when determining a recommendation. Each year, the organization delivers a report to Congress that identifies critical evidence gaps in research and recommends priority areas for further review.
The National Network of Perinatal Quality Collaboratives (NNPQC), sponsored by the CDC, supports state-based perinatal quality collaboratives (PQCs) in measuring and improving upon health care and health outcomes for mothers and babies. These PQCs have contributed to improvements such as reduction in deliveries before 39 weeks, reductions in healthcare associated bloodstream infections, and improvements in the utilization of antenatal corticosteroids.
Telehealth and telemedicine has realized significant growth and development recently. The Center for Connected Health Policy (The National Telehealth Policy Resource Center) has produced multiple reports and policy briefs on the topic of Telehealth and Telemedicine and how they contribute to preventive services. Policy actions and provision of preventive services do not guarantee utilization. Reimbursement has remained a significant barrier to adoption due to variances in payer and state level reimbursement policies and guidelines through government and commercial payers. Americans use preventive services at about half the recommended rate and cost-sharing, such as deductibles, co-insurance, or copayments, also reduce the likelihood that preventive services will be used. Despite the ACA's enhancement of Medicare benefits and preventive services, there were no effects on preventive service utilization, calling out the fact that other fundamental barriers exist.
Preventive care services mainly focus on chronic disease. The Congressional Budget Office has provided guidance that further research is needed in the area of the economic impacts of obesity in the U.S. before the CBO can estimate budgetary consequences. A bipartisan report published in May 2015 recognizes the potential of preventive care to improve patients' health at individual and population levels while decreasing the healthcare expenditure.
According to the American Diabetes Association (ADA), medical costs for employees with diabetes are twice as high as for workers without diabetes and are caused by work-related absenteeism ($5 billion), reduced productivity at work ($20.8 billion), inability to work due to illness-related disability ($21.6 billion), and premature mortality ($18.5 billion). Reported estimates of the cost burden due to increasingly high levels of overweight and obese members in the workforce vary, with best estimates suggesting 450 million more missed work days, resulting in $153 billion each year in lost productivity, according to the CDC Healthy Workforce.
The health capital model explains how individual investments in health can increase earnings by "increasing the number of healthy days available to work and to earn income."Folland, S., Goodman, A.C., & Stano, M. (2016). Demand for Health Capital. The Economics of Health and Healthcare, 7th ed. (p. 130). New York, NY: Routledge. In this context, health can be treated both as a consumption good, wherein individuals desire health because it improves quality of life in the present, and as an investment good because of its potential to increase attendance and workplace productivity over time. Preventive health behaviors such as healthful diet, regular exercise, access to and use of well-care, avoiding tobacco, and limiting alcohol can be viewed as health inputs that result in both a healthier workforce and substantial cost savings.
Cost-saving and cost-effective benefits of preventive care measures are well established. The Robert Wood Johnson Foundation evaluated the prevention cost-effectiveness literature, and found that many preventive measures meet the benchmark of <$100,000 per QALY and are considered to be favorably cost-effective. These include screenings for HIV and chlamydia, cancers of the colon, breast and cervix, vision screening, and screening for abdominal aortic aneurysms in men >60 in certain populations. Alcohol and tobacco screening were found to be cost-saving in some reviews and cost-effective in others. According to the RWJF analysis, two preventive interventions were found to save costs in all reviews: childhood immunizations and counseling adults on the use of aspirin.
According to the Racial and Ethnic Approaches to Community Health (REACH), a national CDC program, non-Hispanic blacks currently have the highest rates of obesity (48%), and risk of newly diagnosed diabetes is 77% higher among non-Hispanic blacks, 66% higher among Hispanics/Latinos and 18% higher among Asian Americans compared to non-Hispanic whites. Current U.S. population projections predict that more than half of Americans will belong to a minority group by 2044. Without targeted preventive interventions, medical costs from chronic disease inequities will become unsustainable. Broadening health policies designed to improve delivery of preventive services for minority populations may help reduce substantial medical costs caused by inequities in health care, resulting in a return on investment.
There are dozens of current policies acting at either (or all of) the federal, state, local and school levels. Most states employ a physical education requirement of 150 minutes of physical education per week at school, a policy of the National Association of Sport and Physical Education. In some cities, including Philadelphia, a sugary food tax is employed. This is a part of an amendment to Title 19 of the Philadelphia Code, "Finance, Taxes and Collections", Chapter 19-4100, Sugar-Sweetened Beverage Tax that was approved 2016, which establishes an excise tax of $0.015 per fluid ounce on distributors of beverages sweetened with both caloric and non-caloric sweeteners. Distributors are required to file a return with the department, and the department can collect taxes, among other responsibilities. These policies can be a source of tax credits. Under the Philadelphia policy, businesses can apply for tax credits with the revenue department on a first-come, first-served basis. This applies until the total amount of credits for a particular year reaches one million dollars.
Recently, advertisements for food and beverages directed at children have received much attention. The Children's Food and Beverage Advertising Initiative (CFBAI) is a self-regulatory program of the food industry. Each participating company makes a public pledge that details its commitment to advertise only foods that meet certain nutritional criteria to children under 12 years old. This is a self-regulated program with policies written by the Council of Better Business Bureaus. The Robert Wood Johnson Foundation funded research to test the efficacy of the CFBAI. The results showed progress in terms of decreased advertising of food products that target children and adolescents.
The CDC website describes a federally funded program, Vaccines for Children (VFC), which provides vaccines at no cost to children who might not otherwise be vaccinated because of inability to pay. Additionally, the Advisory Committee on Immunization Practices (ACIP) is an expert vaccination advisory board that informs vaccination policy and guides on-going recommendations to the CDC, incorporating the most up-to-date cost-effectiveness and risk-benefit evidence in its recommendations.
