Levels of Prevention Levels of Prevention The definition of epidemiology encompasses preventing and controlling diseases in human populations. This is usually accomplished using three levels of prevention.

Primary prevention seeks to reduce the frequency of new cases of disease occurring in a population and, thus is most applicable to persons who are in the stage of susceptibility.

Secondary prevention attempts to reduce the number of existing cases in a population and, therefore, is most appropriately aimed those in the stage of presymptomatec disease or the early stage of clinical disease.

Tertiary prevention tries to limit disability and improve functioning following disease or its complications, often through rehabilitation. Therefore, it is most applicable during the late clinical Levels of prevention or the stage of diminished capacity.

The natural history of disease and the levels of prevention are closely linked. As illustrated in figureappropriate levels of prevention may be applied at each stage of the natural history of disease.

Primary Prevention Primary prevention strategies emphasize general health promotion, risk factor reduction, and other health protective measures. These strategies include health education and health promotion programs designed to foster healthier lifestyles and environmental health programs designed to improve environmental quality.

Specific examples of primary prevention measures include immunization against communicable diseases; public health education about good nutrition, exercise, stress management, and individual responsibility for health; chlorination and filtration of public water supplies; and legislation requiring child restraints in motor vehicles.

Secondary Prevention Secondary prevention focuses on early detection and swift treatment of disease. Its purpose is to cure disease, slow its progression, or reduce its impact on individuals or communities. A common approach to secondary prevention is screening for disease, such as the noninvasive computerized test for the early detection of heart disease.

This test uses computerized tomography scans to look for calcium deposition in the arteries, which can signal previously undetected heart disease.

Other examples of screening include mammography for breast cancer detection; eye tests for glaucoma; blood tests for lead exposure; occult blood tests for colorectal cancer; the Pap test for cervical concrete breath test for Helicobacter pylori, the bacterium implicated in duodenal and gastric ulcers; and the Prostate-Specific Antigen PSA test for prostate cancer.

In each case, screening is performed to detect disease early so prompt treatment can be initiated. Examples of other secondary prevention methods include treatment of hypertension to prevent complications and removal of skin cancer lesions as they occur.

Tertiary Prevention Tertiary Prevention strategies involve both therapeutic and rehabilitative measures once disease is firmly established. Examples include treatment of diabetics to prevent complication of the disease and the ongoing management of chronic heart disease patients with medication, diet, exercise, and periodic examination.The Alabama Prevention Newcomer’s Guide (APNG) provides a range of information useful to prevention professionals on all levels.

For those new to the prevention field, both agencies and individuals, the guide serves as an orientation tool. The following diagram may help to clarify these levels of prevention, and to link them to the populations they each target.

Note that there is also a concept of "Primordial prevention" which seeks ways to "avoid the emergence and establishment of the social, economic and. The Levels of Prevention Although many of us are interested in preventing violence, often our efforts are focused in different—but equally necessary— ways.

Understanding the different levels of prevention can help us understand how our efforts complement each other. We were taught that tertiary level of prevention is pretty much rehabilitation after the fact; like the patient actually had the MI or stroke and is rehabilitating from that event. We were taught secondary is the level where a patient has the problem (cardiac disease or hypercholesterolemia) and is being maintained at that level, and the aim is.
