Appropriateness of proton pump inhibitor therapy in an ambulatory geriatrics clinic: A retrospective cross-sectional analysis
Abstract
Background: Proton pump inhibitors are considered potentially inappropriate medications in the geriatric population. The use of proton pump inhibitors by older adults has increased over the past several decades; however, existing literature suggests that only one-third of patients prescribed these medications have a valid indication for use. The aim of this study was to assess the appropriateness of proton pump inhibitor therapy in a population of ambulatory geriatric patients and to determine the impact of an interdisciplinary clinic on their use.
Methods: This was a retrospective, cross-sectional study of patients referred to an ambulatory geriatrics clinic between October 2017 and March 2021. Participants were eligible for inclusion if they were taking a proton pump inhibitor at the time of clinic admission. Appropriateness of proton pump inhibitor therapy was assessed based on indication and dosing regimen.
Results: In total, 280 participants were included. The mean age was 79.6 years (SD 7.7) and 60% were female. Overall, 94 of 280 (33.6%) participants had a documented valid indication for their proton pump inhibitor. The clinic team intervened to reduce the dose or discontinue 76 of 186 (40.8%) inappropriate proton pump inhibitors.
Interpretation: Only one-third of proton pump inhibitors used by ambulatory geriatric patients have a documented appropriate indication for use. Given the medical complexity of this population and their vulnerability to adverse effects, the…
