Abstract
PURPOSE: Medication administration errors remain a persistent issue in the US healthcare system, impacting patient safety and leading to worsened outcomes, including increased mortality. Smart infusion pump interoperability with electronic health records (EHRs) has the potential to reduce intravenous (IV) medication administration errors. Smart Infusion pumps safely deliver IV medications using drug libraries that set standard dosing limits. Interoperability is their ability to wirelessly connect to EHRs to receive medications orders directly minimizing error-prone manual programming steps. However, despite being implemented over a decade ago, its real-world impact remains largely underexplored. METHODS AND MATERIALS: A systematic literature review (SLR) of PubMed/Medline and Embase in November 2024 identified peer-reviewed studies assessing medication administration errors pre- and post- interoperability implementation in the inpatient hospital setting. The primary outcome measured error types directly impacted by interoperability. The secondary outcome assessed the cumulative reduction in medication administration errors. RESULTS: Three studies met the inclusion criteria, spanning general community hospitals, pediatric facilities, and intensive care units (ICUs). For the primary outcome of assessing medication administration errors impactable by interoperability, interoperability implementation resulted in a 15.4% to 54.8% reduction in specific medication administration errors. For the secondary outcome of all medication administration errors, the cumulative reductions in medication administration errors post-implementation ranged from 21.2% to 90.5%, with variability influenced by baseline compliance, study setting, and patient populations. CONCLUSION: Smart infusion pump interoperability demonstrated consistent potential to enhance medication safety by addressing key error types and reducing cumulative errors in real-world settings. However, future research is needed to assess its impact on adverse drug events, clinician workflows, and patient outcomes. These findings underscore the importance of tailored implementation strategies to maximize interoperability's effectiveness in improving patient safety.
