Impact of Unit Dose Medication Distribution Systems on Medication Safety, Nursing Efficiency, and Pharmacy Workflow in Hospital Settings: A Narrative Review

Abstract

Background: Medication distribution is an essential part of hospital practice, yet it remains a source of preventable medication errors and operational difficulties. Nurses and pharmacists share responsibility for ensuring that prescribed medications reach patients safely and on time. Unit dose medication distribution systems have been introduced in many hospitals to improve medication handling, strengthen pharmacy oversight, and reduce unnecessary preparation activities in nursing units.
Objective: This narrative review explores the contribution of unit dose medication distribution systems to medication safety, nursing efficiency, and pharmacy workflow, with particular attention to the practical relationship between nursing and pharmacy departments.
Methods: This narrative review draws on published literature and professional guidance related to hospital medication distribution, medication administration errors, pharmacy automation, and nursing practice. The available evidence is discussed thematically, focusing on the advantages, limitations, and practical implications of unit dose systems. The review does not attempt a systematic synthesis or quantitative estimation of intervention effects.
Discussion: Unit dose distribution changes how medications move through the hospital and how responsibilities are shared between pharmacists and nurses. Pharmacy involvement in medication verification and dose preparation may reduce opportunities for medication selection and preparation errors. Nurses may benefit from more organized medication supplies and reduced handling of bulk medication stock. However, these advantages depend on timely dispensing, clear communication, adequate staffing, and reliable information systems. Centralized distribution may also create new challenges, particularly when medications are urgently needed or orders change frequently.
Conclusion: Unit dose medication distribution can contribute to safer and more organized hospital medication practices. Its success depends not only on the distribution model itself but also on effective collaboration between nurses and pharmacists, appropriate technology, and continuous evaluation of daily clinical workflows
