The Community Tracking Study’s physician surveys are national samples of more than 12,000 physicians conducted for the Center for Studying Health System Change, a nonpartisan policy research organization committed to providing objective research on the nation’s changing health system; the Center is funded by the Robert Wood Johnson Foundation. Surveys have been conducted in 1996-1997 (round 1), 1998-1999 (round 2) and 2000-2001 (round 3). Each survey includes two national samples: a clustered sample with 60 sites and an unclustered sample. Twelve of the 60 sites were randomly selected for more intensive analysis and have larger sample sizes. The clustered site sample also includes an oversampling of primary care physicians. The unclustered national sample was designed to counter the high degree of clustering in the site sample. To facilitate change estimates, a high proportion of prior respondents are included in each new round. We will describe the sampling design, discuss the use of the AMA and AOA files for the sampling frame, and sampling of physicians over repeated intervals.

Learning Objectives:

• To provider health researchers with understanding of issues involved in repeated surveys of physicians using a combination of a clustered and unclustered sampling design.
