Traditional medical care focuses on improving health by identifying and treating health problems that have already produced symptoms or complications. In contrast, preventive medical care focuses on preventing health problems from occurring. Preventive care also focuses on diagnosing problems before symptoms or complications arise, when the chances of recovery are greatest. When done well, prevention improves overall health and reduces health care costs.

The general goal of prevention is to reduce a person’s likelihood of becoming ill or disabled or of dying prematurely. Preventive medical care is not a case of “one size fits all.” Specific goals are developed by and for each person. Specific goals depend heavily on a person’s risk profile, that is, the person’s risk of developing a disease based on such factors as age, sex, genetic background, lifestyle, and physical and social environment. Factors that increase risk are called risk factors.


Some risk factors are beyond a person’s control, such as age, sex, and family history. Other risk factors, such as a person’s lifestyle and physical and social environment, can be altered, potentially decreasing risk of developing disorders. In addition, risk can be reduced through good medical care.

Do-Not-Resuscitate (DNR) Orders
A do-not-resuscitate (DNR) order is a document placed in a person’s medical record by a doctor. It informs the medical staff at a hospital that cardiopulmonary resuscitation (CPR) should not be attempted if a person’s heart and/or breathing stops. CPR is often followed by more drastic measures such as use of electric shocks to the heart or insertion of a breathing tube; a DNR order stops these measures as well. When administered near the end of life, what is the success rate of CPR?
