Restrictions

In preparing the data tapes for these collections, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.

Sample

Stratified multistage probability design. In the first stage the PSUs were selected by a modified probability proportional-to-size procedure using separate sampling frames for SMSAs and for nonmetropolitan counties. The second stage consisted of a probability sample of practicing physicians selected from the master files maintained by the AMA and AOA. Within each PSU, all eligible physicians were stratified by 15 specialty groups. The final stage was the selection of patient visits within the annual practices of sample physicians. This involved two steps. First, the total physician sample was divided into 52 with each physician randomly assigned to one of the 52 weeks in the survey year. Second, a systematic random sample of visits was selected by the physician during the assigned week.

Universe

Office visits to nonfederally employed physicians classified by the American Medical Association (AMA) or the American Osteopathic Association (AOA) as "office-based, patient care" (excluding specialties of anesthesiology, pathology, and radiology), from 84 Primary Sampling Units (PSUs) in the United States.
