PURPOSE: The fast-paced environment of the emergency department (ED), with frequent admissions, discharges, and transfers, poses a challenge for pharmacy departments to effectively distribute and store medications. The purpose of this study is to propose a unique workflow of patient-specific medication delivery to the ED from a hospital pharmacy to reduce the number of missing medications resulting in medication messages and redispenses.

METHODS: The medication delivery workflow proposed in this study consists of batching the preparation and distribution of patient-specific medications sent from the pharmacy to the ED in the 1 to 2 hours prior to their administration time. Chi-square analysis was completed to compare medication redispenses and "missing medication" messages before and after the intervention, with the significance level set at P < 0.05.

RESULTS: The percentage of redispensed medications was effectively decreased following implementation of the workflow change from 21.6% to 9.2% (P < 0.001), with unit doses having the greatest reduction (25.8% vs 6.1%, P < 0.001). Benefits of this workflow change were also illustrated through a reduction in the percentage of missing-medication messages sent by nursing staff from 97.7% to 93.9% (P < 0.001).

CONCLUSION: This study showed that implementation of standard, hourly batches of medications dispensed from the pharmacy to the ED resulted in a significant reduction in the total percentage of redispensed medications and missing-medication messages. The overall reduction in redispensed medications as a result of this innovative workflow change not only benefited nursing and pharmacy staff but can reduce medication waste and improve patient care through timely administration of medications.
