Use of a trigger tool to describe and screen drug-related hospital admissions in older adults: the TRIGGAge retrospective cohort study.

This article focuses on the prevalence, causes, and detection of drug-related hospital admissions (DRAs) in older adults using a revised trigger tool in a French acute geriatric ward. In a retrospective cohort of 483 patients (mean age 86.7 years), 43% of admissions were identified as DRAs, with 70% considered preventable; the main causes were falls/fractures, bleeding, and delirium, primarily linked to diuretics, renin–angiotensin system inhibitors, and direct oral anticoagulants. The revised trigger tool demonstrated high sensitivity (90%) and moderate specificity (72%) in detecting DRAs, identifying 83% more cases than attending geriatricians alone. The study highlights the frequent use of medications associated with DRAs in geriatric care and suggests that systematic use of such a tool may improve detection and prevention of these admissions.
