Abstract

Patients are selected for referral to academic medical centers on the basis of age, severity of disease, presence of complications, and other factors. This selection process alters the clinical spectrum of diseases or surgical conditions as seen at major medical centers and, therefore, also influences the perceived natural history of these conditions. The resulting distortion between the natural history of a disease at large medical centers and that in the community is called selection bias. This selection bias can cause disagreement between practitioners in the community and those at teaching centers regarding the definition of and risk factors for various diseases, the utility of laboratory tests, the prognosis to be expected in a given group of patients, and the effectiveness of specific therapeutic or prophylactic procedures.
