Abstract:
|
Health surveys targeting physicians historically have had difficulties in obtaining high response rates. Response rates to the National Ambulatory Medical Care Survey (NAMCS) have been declining over the last 10 years. In the NAMCS, a sample of office-based physicians are asked to provide a brief interview about the office practice and to complete a medical record abstract form on a sample of 30 office visits during their randomly-assigned week. NCHS conducted several studies between 2000-2002 to gauge the impact of different methods on physician cooperation. Samples of physicians were randomly assigned to treatment and control groups in 3 studies to test response effects: inclusion of a motivational insert with the introductory letter, offering monetary or token gift, and form length. Only form length had an effect on response rate. Nonresponse reduction & bias strategies are discussed.
