Real-world evidence of the impact of polypharmacy on mortality and recovery after hip fracture in elderly patients.
Observational study in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Polypharmacy is a common problem in older adults with hip fractures and may negatively affect postoperative outcomes. The aim of this study was to evaluate the association between polypharmacy, including severe polypharmacy, and clinical outcomes in older adults admitted to hospital with hip fracture. A real-life observational study was conducted at a tertiary care hospital in Spain, including patients aged ≥ 70 years who underwent hip fracture surgery between January 1, 2017, and December 31, 2018. Data were extracted from electronic medical records, including demographic details, comorbidities, and medication use. Polypharmacy was defined as the use of five or more medications, and severe polypharmacy as the use of ten or more medications. Mortality rates were analyzed at 30 days, 6 months, 1 year, 2 years, and 5 years post-surgery using Kaplan-Meier survival curves and Cox regression analysis. Among 644 patients included (mean age 84.5 years, 70.5% women), 63.8% had polypharmacy and 19.1% had severe polypharmacy. Compared with patients without polypharmacy, those with polypharmacy, regardless of severity, showed higher mortality at 30 days (8.4% and 10.3% vs 3.9%), 6 months (21.3% and 21.4% vs 10.8%), 1 year (26.6% and 33.3% vs 11.6%), 2 years (38.8% and 46.0% vs 14.2%), and 5 years (68.5% and 76.2% vs 26.3%) (all p ≤ 0.05). Crude hazard ratios for 5-year mortality were 3.65 (95% CI 2.73-4.88) for patients taking 5-9 drugs and 4.51 (95% CI 3.26-6.24) for those taking ≥ 10 drugs; after full adjustment, these remained 3.12 and 3.46, respectively. Patients with polypharmacy also had more red blood cell transfusions, major complications, and worse functional recovery. Polypharmacy was associated with worse postoperative morbidity, poorer functional recovery, and higher mortality in older adults with hip fracture. These findings suggest that medication burden may serve as a marker of clinical vulnerability rather than an isolated causal factor. Prospective interventional studies are needed to determine whether medication optimization improves outcomes.
