Evaluation of an inpatient decentralized pharmacy team program in an HMO setting.

Decentralized drug distribution and clinical pharmacy services were implemented on two nursing units, orthopedics and oncology, of a health maintenance organization-owned hospital. The use of targeted high-cost drugs was assessed before and during the decentralized pharmacy services intervention on the experimental units and on a comparison unit. Other assessments included a survey of nurses from the experimental units and surveillance of telephone encounters between the central pharmacy and the experimental units. In the experimental units, there were significant changes in cefazolin therapy for prophylaxis, aminoglycoside therapy, and metoclopramide use from baseline to the intervention periods. Cefazolin use for prophylaxis essentially remained the same in the comparison unit. Telephone encounters decreased substantially from the before- to the during-program period. An increase in the proportion of inappropriately drawn aminoglycoside blood levels was also noted in the during-program period. Decentralized pharmacy services appeared to reduce the cost of targeted drugs and improve communications with the nursing units.
