Abstract
Background: Automated dispensing cabinets (ADCs) are used to store and dispense medications at the point of care. Medications accessed from an ADC before pharmacist order verification are removed using override functionality. Bypassing pharmacist verification can lead to medication errors; therefore, The Joint Commission considers overrides acceptable only in limited scenarios. During an 18-month period, the override rate in our perianesthesia care unit (PACU) was 17%, with oral midazolam accounting for roughly 40% of overrides. A multidisciplinary quality improvement (QI) project was initiated with a goal to reduce overrides by 10% (17% to 15%) by December 31, 2021.
Methods: Key drivers for reducing overrides included timely medication order entry, nursing practice to wait for verification, and timely pharmacist medication order verification. Interventions related to the latter two drivers included nursing education, individual interviews, and a workflow change involving nurse-to-pharmacy communication prior to medication overrides. Interventions were implemented in three Plan-Do-Study-Act cycles beginning in July 2021. Outcome metrics were average monthly percentage of total medication overrides and overrides for oral midazolam, which were analyzed using statistical process control charts.
Results: Following interventions, the average monthly percentage of total medication overrides decreased from 17% to 8% in July 2021, and further to 4% in February 2022. Oral midazolam overrides decreased from 22% to 9% in July 2021, and further to 3% in February 2022.
Conclusion: Both total and oral midazolam overrides were reduced by changing nursing and pharmacy workflow. Reducing ADC overrides is a complex process balancing operational flow and safety efforts.
