Evaluating the impact of education by a clinical pharmacist on antibiotic prescribing and administration in an acute care state psychiatric hospital.

An antibiotic utilization review program was implemented by a clinical pharmacist in an acute care state psychiatric facility. Antibiotic utilization was concurrently audited in 61 antibiotic orders, written for 48 patients, in order to determine antibiotic prescribing and administration practices and problems. Interventions, consisting of educational presentations, problem-solving meetings, and distribution of written educational materials, were provided by a clinical pharmacist to improve antibiotic prescribing and administration practices. A second audit of 68 antibiotic orders written for 47 patients was concurrently audited after completion of the interventions. When prescribing problems were detected, the clinical pharmacist made recommendations to the prescribing physician. Statistically significant changes in the use of culture and sensitivity tests, appropriate dosage regimens, correct antibiotic administration, and selection of cost-effective therapy were found after all educational interventions were provided. A positive trend not resulting in statistical significance was noted for documentation of infectious disease and selection of appropriate antibiotic agents. This study demonstrates a drug utilization review role for clinical pharmacist's involvement in the acute care psychiatric facility, and illustrates one method by which clinical pharmacists can provide educational programs to improve nonpsychotropic drug prescribing and administration in this setting.
