Presentation of drug prescribing guidelines and physician response.

Most Medicaid Drug Use Review (DUR) Programs disseminate prescribing practice guidelines by providing written reviews to physicians about specific prescribing practices that do not follow established criteria and inviting their comment. This study reviewed physicians' written responses to explore relationships between DUR communications and the degree to which these communications affect awareness of prescribing issues, increase knowledge, change erroneous beliefs, and generate intentions to apply the information appropriately. The form, content, and effective tone for all responses received in 1990 regarding five different drug therapy issues (N = 240) was recorded. Response rates, comprehension, counterarguments, and prescribing intentions varied by drug therapy issue. Attention to the communication process could improve the dissemination of prescribing practice guidelines by DUR Programs.
