Implementation and evaluation of a decentralized pharmacy service.

The implementation of a decentralized pharmacy service on a 59 bed acute patient care area was evaluated. Over a ten-month period four criteria were used to evaluate the decentralized service: (1) reported medication errors, (2) reported medication discrepancies, (3) drug costs per patient day and (4) availability and utilization of drug information. Data was collected over the ten month period for all criteria except for drug information interactions in which a self reporting data card was utilized over a six week period. Medication errors and medication discrepancies decreased by 12.5% and 80% respectively on the pilot floor as compared to the hospital (+14.8%, -18.0% respectively). Drug costs per patient day increased the least on the pilot floor (+9.1%) as compared to other areas in the hospital (range: 10.8% to 49.3%). Seventy-six percent of drug information interactions occurred on the pilot floor as compared to the central pharmacy accounting for 24% of interactions for all other hospital areas combined. It is concluded that a decentralized pharmacy service can make a significant impact on a unit dose drug distribution system by reducing medication errors, discrepancies, drug costs and by increasing the utilization of drug information resources.
