Hospital-wide interventions for reducing or preventing in-hospital prescribing errors: a scoping review.

INTRODUCTION

Prescribing errors (PEs) in hospital care lead to patient harm, prolonged hospital stays, readmissions, and mortality. Despite interventions that successfully target 'high risk' populations in trials, PE rates remain largely unchanged in real-world settings. Existing studies often focus narrowly on specific populations, overlooking the wider complexities of hospital-wide prescribing. This scoping review evaluates interventions for adult inpatients to identify knowledge gaps in how to reduce in-hospital PEs.

METHODS

A systematic search of PubMed, EMBASE.com, and the Cochrane Library (inception to 13 December 2024) was conducted following PRISMA-ScR guidelines. Studies prospectively evaluating interventions reducing in-hospital PEs were eligible for inclusion; those focusing on specific drugs, wards or populations or lacking original data were excluded.

RESULTS

Fourteen studies met the inclusion criteria. Technological interventions, such as computerized order entry systems, accounted for 35.7% of the studies. Half addressed prescriber-related factors, such as inadequate drug knowledge and prescribing skills, while organizational factors were underexplored.

CONCLUSION

Current interventions fail to address the underlying complexities, leaving critical gaps to decrease in-hospital PEs. To achieve sustainable PE reductions and improve patient safety, a multidisciplinary approach, standardized reporting, organizational reform, and a Safety-II perspective are essential.
