OBJECTIVE: To compare the appropriateness of omeprazole prescriptions in a concurrent drug utilization review (DUR) with the assessed appropriateness of a retrospective DUR.
METHODS: A retrospective DUR of omeprazole was conducted on prescriptions written from August 23, 1993, to October 8, 1993, in a 340-bed university hospital. This DUR served as a baseline for a concurrent DUR that began on January 27, 1995, and ended on March 16, 1995. The concurrent DUR integrated three steps aimed at improving the quality of omeprazole use: approval of the criteria by the pharmacology and therapeutics committee of the hospital, distribution of a drug bulletin to all physicians, and a pharmacist’s verbal recommendations to physicians whose prescriptions did not meet explicit criteria.
RESULTS: Twenty-nine and 64
prescriptions were reviewed in the retrospective and concurrent DURs,
respectively. During the concurrent DUR, the pharmacist made 34 verbal
recommendations. Of these, 25 (74%) were agreed to by the prescribers. In
comparison with the retrospective DUR, the percentage of prescriptions meeting
the criteria of indication, combination therapy, and dosage went from 38% to
75%
(p < 0.05), from 76% to 95% (p < 0.05), and from 83% to 100% (p
> 0.05), respectively, during the concurrent DUR.
CONCLUSIONS: The concurrent DUR appeared to successfully improve the quality of omeprazole utilization in the hospital.
