ABSTRACT
BACKGROUND: In a population of 85 general practitioners diagnostic test ordering behaviour has been changed by means of repeated individual feedback provided since 1985. OBJECTIVES: We studied practitioner and practice characteristics which may explain differences in test ordering behaviour and in the extent to which general practitioners tend to change their behaviour according to the feedback. METHOD: In order to trace such variables, 75 general practitioners were interviewed. In our study request data from individual general practitioners were related to data from several questionnaires. RESULTS: We found no practice characteristics which were of influence on the number of test requests by the general practitioner. Explanatory practitioner characteristics for this were found to be years of experience and working hours per week in practice. CONCLUSIONS: More years of experience as a general practitioner and a shorter duration of consultations correlated with a better response to advice given in the feedback.

Feedback can be described as a way to provide information on doctors' performance to enable changes in future behaviour. Feedback is used with the aim of changing test-ordering behaviour. It can lead to reductions in test usage and cost savings. It is not sufficiently clear, however, whether feedback leads to more appropriate test use. Since 1985, the Diagnostic Coordinating Center Maastricht has been giving feedback on diagnostic tests as a routine health care activity to all family doctors in its region. Both quantity and quality of requests are discussed. In a randomised, controlled trial over 2.5 years, discussion of tests not included previously was added to the existing routine feedback. One group of family doctors (n = 39) received feedback on test-group A (electrocardiography, endoscopy, cervical smears, and allergy tests), the other (n = 40) on test-group B (radiographic and ultrasonographic tests). Thus, each group of doctors acted as a control group for the other. Changes in volume and rationality of requests were analysed. The number of requests decreased during the trial (p = 0.036). Request numbers decreased particularly for test-group A (p = 0.04). The proportion of requests that were non-rational decreased more in the intervention than in the control groups (p = 0.009). Rationality improved predominantly for test-group B (p = 0.043). Thus, routine feedback can change the quantity and quality of requests.
