I Universidade Federal de Santa Catarina. Quaternary prevention consists in the identification of persons at risk of excessive medicalization and their protection against new unnecessary interventions, avoiding iatrogenic damages. Here, we argue about the importance of quaternary prevention in specific primary and secondary prevention.

Preventive healthcare

Preventive healthcare , or prophylaxis , consists of measures taken for disease prevention. Disease prevention relies on anticipatory actions that can be categorized as primal, [2] [3] primary, secondary, and tertiary prevention. Each year, millions of people die of preventable deaths. A study showed that about half of all deaths in the United States in were due to preventable behaviors and exposures. There are many methods for prevention of disease. One of them is prevention of teenage smoking through information giving.

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 genetic disorders or predisposition to certain diseases such as breast or ovarian cancer. Preventive healthcare strategies are described as taking place at the primal, [2] primary, [13] secondary, and tertiary prevention levels.

Although advocated as preventive medicine in the early twentieth century by Sara Josephine Baker , [14] in the s, Hugh R. Leavell and E. Gurney Clark coined the term primary prevention. They worked at the Harvard and Columbia University Schools of Public Health, respectively, and later expanded the levels to include secondary and tertiary prevention. Goldston notes that these levels might be better described as "prevention, treatment, and rehabilitation", although the terms primary, secondary, and tertiary prevention are still in use today.

The concept of primal prevention has been created much more recently, in relation to the new developments in molecular biology over the last fifty years, [15] more particularly in epigenetics, which point to the paramount importance of environmental conditions - both physical and affective - on the organism during its fetal and newborn life or so-called primal period of life.

Primordial prevention refers to measures designed to avoid the development of risk factors in the first place, early in life. Primal prevention has been propounded as a separate category of health promotion. This health promotion par excellence [21] is based on knowledge in molecular biology, in particular on epigenetics , which points to how much affective as well as physical environment during fetal and newborn life may determine adult health.

This includes adequate parental leave [26] ideally for both parents with kin caregiving and financial help where needed. Primordial prevention refers to all measures designed to prevent the development of risk factors in the first place, early in life, [16] [17] and even preconception, as Ruth 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 [27] or prohibiting endocrine-disrupting chemicals in food-handling equipment and food contact materials.

Primary prevention consists of traditional health promotion and "specific protection. Preventing disease and creating overall well-being, prolongs life expectancy. Food is the most basic tool in preventive health care. The National Health Interview Survey performed by the Centers for Disease Control was the first national survey to include questions about ability to pay for food. Difficulty with paying for food, medicine, or both is a problem facing 1 out of 3 Americans.

If better food options were available through food banks , soup kitchens, and other resources for low-income people, obesity and the chronic conditions that come along with it would be better controlled. These are often low-income neighborhoods with the majority of residents lacking transportation.

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.

Secondary prevention deals with latent diseases and attempts to prevent an asymptomatic disease from progressing to symptomatic disease. This depends on definitions of what constitutes a disease, though, in general, primary prevention addresses the root cause of a disease or injury [18] whereas secondary prevention aims to detect and treat a disease early on.

Disability limitation for syphilitic patients includes continued check-ups on the heart, cerebrospinal fluid, and central nervous system of patients to curb any damaging effects such as blindness or paralysis.

Finally, tertiary prevention attempts to reduce the damage caused by symptomatic disease by focusing on mental, physical, and social rehabilitation. Unlike secondary prevention, which aims to prevent disability, the objective of tertiary prevention is to maximize the remaining capabilities and functions of an already disabled patient.

The leading cause of death in the United States was tobacco. However, poor diet and lack of exercise may soon surpass tobacco as a leading cause of death.

These behaviors are modifiable and public health and prevention efforts could make a difference to reduce these deaths. The leading causes of preventable death worldwide share similar trends to the United States.

There are a few differences between the two, such as malnutrition, pollution, and unsafe sanitation, that reflect health disparities between the developing and developed world. In , 7. While this is a decrease from 9. Targeting efforts in these countries is essential to reducing the global child death rate. Child mortality is caused by factors including poverty, environmental hazards, and lack of maternal education. The table indicates how many infant and child deaths could have been prevented in the year , assuming universal healthcare coverage.

Obesity is a major risk factor for a wide variety of conditions including cardiovascular diseases, hypertension, certain cancers, and type 2 diabetes. In order to prevent obesity, it is recommended that individuals adhere to a consistent exercise regimen as well as a nutritious and balanced diet. The medical system in our society is geared toward curing acute symptoms of disease after the fact that they have brought us into the emergency room.

An ongoing epidemic within American culture is the prevalence of obesity. Healthy eating and regular exercise play a significant role in reducing an individual's risk for type 2 diabetes. A study concluded that about Ninety to 95 percent of people with diabetes have type 2 diabetes. Diabetes is the main cause of kidney failure, limb amputation, and new-onset blindness in American adults. STIs can be asymptomatic, or cause a range of symptoms. Preventive measures for STIs are called prophylactics.

The term especially applies to the use of condoms , [41] which are highly effective at preventing disease, [42] but also to other devices meant to prevent STIs, [41] such as dental dams and latex gloves. Other means for preventing STIs include education on how to use condoms or other such barrier devices , testing partners before having unprotected sex, receiving regular STI screenings, to both receive treatment and prevent spreading STIs to partners, and, specifically for HIV, regularly taking prophylactic antiretroviral drugs, such as Truvada.

Post-exposure prophylaxis , started within 72 hours optimally less than 1 hour after exposure to high-risk fluids, can also protect against HIV transmission. Genetically modified mosquitoes are being used in developing countries to control malaria. This approach has been subject to objections and controversy. Thrombosis is a serious circulatory disease affecting thousands, usually older persons undergoing surgical procedures, women taking oral contraceptives and travelers.

The consequences of thrombosis can be heart attacks and strokes. Prevention can include: exercise, anti-embolism stockings, pneumatic devices, and pharmacological treatments. In recent years, cancer has become a global problem. Low and middle income countries share a majority of the cancer burden largely due to exposure to carcinogens resulting from industrialization and globalization.

Primary prevention of cancer can also prevent other diseases, both communicable and non-communicable, that share common risk factors with cancer. Lung cancer is the leading cause of cancer-related deaths in the United States and Europe and is a major cause of death in other countries. Other carcinogens include asbestos and radioactive materials. Individual, community, and statewide interventions can prevent or cease tobacco use.

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. 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.

This program was therefore effective in secondary but not primary prevention and shows that school-based programs have the potential to reduce tobacco use. Skin cancer is the most common cancer in the United States. Furthermore, childhood prevention can lead to the development of healthy habits that continue to prevent cancer for a lifetime. 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.

Most skin cancer and sun protection data comes from Australia and the United States. However, many adolescents purposely used sunscreen with a low sun protection factor SPF in order to get a tan. Cervical cancer ranks among the top three most common cancers among women in Latin America , sub-Saharan Africa , and parts of Asia.

Cervical cytology screening aims to detect abnormal lesions in the cervix so that women can undergo treatment prior to the development of cancer. Finland and Iceland have developed effective organized programs with routine monitoring and have managed to significantly reduce cervical cancer mortality while using fewer resources than unorganized, opportunistic programs such as those in the United States or Canada.

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 s. 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. Brazil, Peru, India, and several high-risk nations in sub-Saharan Africa which lack organized screening programs, have a high incidence of cervical cancer.

Colorectal cancer is globally the second most common cancer in women and the third-most common in men, [57] and the fourth most common cause of cancer death after lung , stomach , and liver cancer , [58] having caused , deaths in It is also highly preventable; about 80 percent [60] of colorectal cancers begin as benign growths , commonly called polyps , 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 see Colorectal cancer.

Access to healthcare and preventive health services is unequal, as is the quality of care received. The same trends are seen when comparing all racial minorities black, Hispanic, Asian to white patients, and low-income people to high-income people. Minorities were less likely than whites to possess health insurance, as were individuals who completed less education. These disparities made it more difficult for the disadvantaged groups to have regular access to a primary care provider, receive immunizations, or receive other types of medical care.

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.

Preventive healthcare

In general, preventive care refers to measures taken to prevent diseases instead of curing or treating the symptoms. The three levels of preventive care—primary, secondary, and tertiary care—are detailed below:. Primary prevention aims to avoid the development of a disease or disability in healthy individuals.

Quaternary prevention should be implemented to minimize harm to patients because the ultimate goal of medicine is to prevent disease and promote health. Primary care physicians have a major responsibility in quaternary prevention, and the establishment of clinical epidemiology as a distinct field of study would create a role charged with minimizing patient harm arising from over-medicalization.

Carlos G. Emilio Ravignani , Buenos Aires, Argentina. This paper reviews the evidence supporting the use of etiological treatment for Chagas disease that has changed the standard of care for patients with Trypanosoma cruzi infection in the last decades. Implications of this evidence on different levels of prevention as well as gaps in current knowledge are also discussed. In this regard, etiological treatment has shown to be beneficial as an intervention for secondary prevention to successfully cure the infection or to delay, reduce, or prevent the progression to disease, and as primary disease prevention by breaking the chain of transmission.
