Retrospective analysis of mortality and the influence of polypharmacy in geriatric staircase falls.
Article in BMC geriatrics, 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
backgroundStaircase falls are a significant cause of emergency department visits among older adults (≥ 65 years) and are associated with increased morbidity and mortality. While previous research has explored risk factors for injury severity, the role of polypharmacy (≥ 5 regular medications) in influencing injury patterns and clinical outcomes remains unclear.
methodsA retrospective analysis was conducted using patient records from a university hospital emergency department within a five-year observation period, with a minimum follow-up of two years. Demographic data, health status, injury patterns, and outcomes were analyzed. Survival analysis was performed to assess the impact of polypharmacy on long-term survival.
resultsA total of 529 patients were included, of whom 243 (45.9%) were classified as polypharmacy patients. Polypharmacy patients were significantly older (mean age 79.18 vs. 76.45 years, p < 0.001) and had higher comorbidity burdens, including increased BMI, dementia, depression, and previous falls (p < 0.05). Although polypharmacy was not significantly associated with specific injury patterns, it was linked to worse clinical outcomes. Patients with polypharmacy were more likely to require inpatient admission (70.8% vs. 62.2%) and had lower long-term survival rates (p = 0.014). After adjusting for covariates, polypharmacy remained an independent risk factor for mortality (p = 0.042).
conclusionPolypharmacy is prevalent among older adults with staircase falls and is associated with increased frailty, comorbidities, and poor clinical outcomes, including higher mortality. These findings underscore the need for targeted medication management and comprehensive fall prevention strategies to improve outcomes in this vulnerable population group.
