Definition
A physical examination is the evaluation of a body to determine its state of health. The techniques of inspection include palpation (feeling with the hands and/or fingers), percussion (tapping with the fingers), auscultation (listening), and smell. A complete health assessment also includes gathering information about a person's medical history and lifestyle, conducting laboratory tests, and screening for disease. These elements constitute the data on which a diagnosis is made and a plan of treatment is developed.
Purpose
The term annual physical examination has been replaced in most health care circles by periodic health examination. The frequency with which it is conducted depends on factors such as the age, gender, and the presence of risk factors for disease in the person being examined. Health-care professionals often use guidelines that have been developed by organizations such as the United States Preventative Services Task Force. Organizations such as the American Cancer Society or American Heart Association, which promote detection and prevention of specific diseases, generally recommend more intensive or frequent examinations, or suggest that examinations be focused on particular organ systems of the body.
Comprehensive physical examinations provide opportunities for health care professionals to obtain baseline information about individuals that may be useful in the future. They also allow health care providers to establish relationships before problems occur. Physical examinations are appropriate times to answer questions and teach good health practices. Detecting and addressing problems in their early stages can have beneficial long-term results.
Every person should have periodic physical examinations. These occur frequently (monthly at first) in infants and gradually reach a frequency of once per year for adolescents and adults.
