Abstract
BACKGROUND: Polypharmacy and fall-risk increasing drugs (FRIDS) have been associated with injurious falls. We aimed to estimate the prevalence of polypharmacy and FRIDS in older patients discharged from an Orthogeriatric Unit after a hip fracture surgery. METHODS: This study describes the baseline findings of a 2-year retrospective cohort study. We included patients older than 80 years discharged from an Orthogeriatric Unit who were able to walk before surgery. Patient's baseline variables, total number of drugs, and FRIDS at hospital discharge were collected. RESULTS: We included 228 patients. The mean number of drugs and FRIDS prescribed at discharge was 11.6 ± 3.0 and 2.9 ± 1.6, respectively. Polypharmacy was prevalent in all patients except in three: 23.3% (5-9 drugs) and 75.9% (≥ 10 drugs). Only 11 patients had no FRIDS and 35.5% were on > 3 FRIDS. The most prevalent FRIDS were: agents acting on the renin-angiotensin system (43.9%) and anxiolytics (39.9%). The number of FRIDS was higher in patients with extreme polypharmacy (3.4 ± 1.5) than in those on 5-9 drugs (1.5 ± 1.0, p < 0.05). Independent people in performing instrumental activities had lower risk of extreme polypharmacy (≥ 10 drugs) or > 3 FRIDS: OR 0.39 (95% CI 0.18-0.83) and OR 0.41 (95% CI 0.20-0.84), respectively. People living in a nursing home had higher risk of > 3 FRIDS: OR 4.03 (95% CI 1.12-14.53). CONCLUSIONS: Polypharmacy and fall-risk increasing drugs are prevalent in patients discharged from orthogeriatric care after surgery for a hip fracture. Interventions on drug use at hospital discharge could have a potential impact on falls in this high-risk population.
