Intervention to improve the appropriate use of polypharmacy for older patients with hip fractures: an observational study

Authors: Junpei Komagamine, Kazuhiko Hagane

Published in: BMC Geriatrics | Issue 1/2017

Abstract

Background

Polypharmacy is frequently observed in hip fracture patients. Although it is associated with an increased risk of hip fracture, polypharmacy often continues after hip fracture recovery. This study aimed to evaluate the effectiveness of an intervention to improve appropriate polypharmacy for elderly patients admitted to the hospital for hip fractures.

Methods

We conducted a retrospective observational study to compare the outcomes of patients receiving the intervention (n = 32) with those of patients who received usual care (n = 132). All hip fracture patients aged 65 years or older and prescribed 5 or more medications at admission from January 2015 to December 2016 were included in the study. The intervention consisted of an assessment by internal medicine physicians of the appropriateness of polypharmacy and the de-prescription of any unnecessary medications during the patients’ hospital stay. The primary composite outcome was death or the first occurrence of any new fracture. Comparisons between the intervention and usual care groups were analyzed using binary logistic regression.

Results

A total of 164 patients were included in the study. The mean patient age was 84.8 years, and the mean numbers of prescribed medications and potentially inappropriate medications at admission were 8.0 and 1.3, respectively. The mean follow-up period was 8.0 months. The primary composite outcome occurred in 35 (21.3%) patients. The total number of potentially inappropriate medications at discharge was significantly lower in the intervention group than in the usual care group (0.8 ± 0.8 for the intervention group vs 1.1 ± 1.0 for the usual care group; p = 0.03). However, no significant differences in the primary composite outcome were found between the intervention and usual care groups (7 in the intervention group and 28 in the usual care group, odds ratio 1.04, 95% CI 0.41–2.65; p = 1.00).

Conclusions

The intervention to improve appropriate polypharmacy was associated with a reduction in potentially inappropriate medications but not an improvement in clinical outcomes. This intervention, which focused only on polypharmacy, may not effectively improve outcomes for elderly patients with hip fractures.
