[A utilization review program of cefoxitin]

A drug utilization review program of cefoxitin was conducted in a 714-bed teaching hospital. Health records of all 43 in-patients who received cefoxitin during the month of November 1987 were reviewed retrospectively. The use of cefoxitin (47 courses) was evaluated on the basis of "appropriate use" criteria developed from the literature and the physician's clinical experience. Of the 47 courses evaluated, cefoxitin was prescribed for prophylaxis in 47%, and its use was considered inappropriate in 86% of these. Overall, 66% of total cefoxitin usage was deemed inappropriate in this hospital. The cost associated with inappropriate use was estimated at $2672 for the period of the study. Corrective measures were then implemented to rectify the identified problems. A second study was conducted 2 years later to assess the impact of the corrective measures. This utilization review program of cefoxitin showed that optimal use of a drug requires not only close collaboration between pharmacists and physicians but a continuous and not a sporadic process of surveillance of the prescription for the drug being studied.
