Medication-related hospital admissions in aged care residents

Abstract

Objective To determine the prevalence of medication-related hospitalisations preceded by potentially suboptimal processes of care in aged care residents. Method We conducted a retrospective analysis of administrative claims data from the Australian Government Department of Veterans’ Affairs (DVA). We identified all hospital admissions for aged care residents between 1 July 2014 and 30 June 2019. The proportion of hospital admissions preceded by potentially suboptimal medication-related processes of care was determined. Results A total of 18 874 hospitalisations were included, and 46% were preceded by potentially suboptimal medication-related care. One-quarter of fracture admissions occurred in residents at risk of fracture who were not using a medicine to prevent fracture, and 87% occurred in residents using falls-risk medicines. Thirty per cent of heart failure admissions occurred in patients who were not using an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker. Conclusion Nearly half of hospital admissions were preceded by potentially suboptimal medication-related processes of care. Interventions to improve use of medicines for aged care residents in these areas are warranted.
