Effect of computer-generated prompts on physician prescribing of multiple daily doses.
Cost containment of health care costs and computerization of pharmacy services are two trends that have become evident in recent years. The work described here was an attempt to reduce the prescribing of multiple daily doses of medications that could be prescribed once or twice daily by utilizing a pharmacy computer system. Ten drugs were identified as being prescribed more than 30% of the time in more frequent dosing schedules than recommended in the literature. Five of the drugs were randomly assigned to an experimental group and five to a control group. The computer system included a reminder with all experimental drug group orders for drugs effective given once or twice daily for maintenance therapy. This reminder was printed on both the physician's active medication profile and the nurse's medication administration record. The control period was designated as being the four month period prior to the initiation of the study. The experimental period was identified as the following four months where reminders were included with the drugs. No information concerning the study was circulated to the physicians or nursing staff. The results revealed no trend of fewer orders for multiple doses in the experimental group. In fact, all drugs in both the experimental and control groups showed random fluctuations in the number of orders for multiple doses. Possible reasons for the failure of this project include the impact of the reminders on the physicians, the timing of the study, and the medical condition of the patients.
