Challenges and Opportunities in the Medication Reconciliation Process in an Emergency Department: An Observational Human Factors Study.

OBJECTIVES

This observational study examines challenges and opportunities in the medication reconciliation process within the emergency department (ED). Through a human factors approach, we look to identify barriers and potential improvements for enhancing patient safety during transitions of care for older adults.

METHODS

An observational study was conducted in the ED of a large teaching hospital, comprising 32 hours of observation across 12 sessions. Researchers followed pharmacists, nurses, and triage staff, documenting workflows, communication practices, and medication reconciliation processes. Recurring patterns, challenges, and opportunities for improvement were identified through a qualitative analysis.

RESULTS

Systemic barriers to effective medication reconciliation were identified, including fragmented workflows, inconsistent documentation, and usability issues in electronic health records. Challenges were exacerbated by the fast-paced ED environment and frequent interruptions. Pharmacists played a pivotal role in synthesizing diverse information sources to construct accurate medication histories, but their workload often limited their capacity to address broader medication safety concerns. Opportunities for improvement include delegating specific tasks to trained support staff, optimizing electronic health record functionalities, and fostering interdisciplinary collaboration to streamline workflows and reduce errors.

CONCLUSIONS

Medication reconciliation in the ED is critical for patient safety but faces significant systemic and environmental challenges. Addressing these barriers through enhanced system integration, task delegation, and improved communication protocols could increase efficiency and reduce errors. Further research is needed to evaluate these interventions across diverse ED settings to optimize medication reconciliation processes and improve safety outcomes.
