Analysis of dispensing activities before and after decentralization of pharmaceutical services.

Changes in drug handling activities, revenue, and telephone communications were documented during a conversion from a centralized unit dose system to decentralized pharmacists and unit dose services in a 310-bed university teaching hospital. All decentralized services were mobile; no physical satellites were utilized. Computer programs were used to collect and analyze drug handling and revenue data during a prestudy control period and three equal-length study periods after decentralization of pharmaceutical services for five patient care areas of the hospital. All telephone calls to the central pharmacy were recorded and classified by type during 21 days of the prestudy period and were compared with 21 days of the second postimplementation period. The mean number of doses handled decreased for all patient care areas. After decentralization the number of telephone calls to the central pharmacy requesting clinical drug information, as well as distributive information, decreased sharply. Moving the pharmacist to the patient care unit decreased the time that pharmacists spent handling drugs and improved communication with the medical and nursing staffs.
