Utility of frailty assessment for outcomes in surgical patients aged 75 and over.
Article in BMC geriatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPhysical performance and nutritional status evaluated in frailty are increasingly recognized as important predictors of postoperative outcomes in older adults patients but remain under-assessed during routine preoperative assessment. This study aimed to evaluate the association between frailty tools and 180-day postoperative mortality in patients aged ≥ 75 years undergoing surgery.
methodsWe conducted a single-center retrospective cohort study over a five-year period (2020–2024). Patients aged ≥ 75 years who underwent surgery under anesthesia were included. Data were extracted from a structured hospital database, and frailty was assessed using the Mini Nutritional Assessment – Short Form (MNA), the SARC-F questionnaire (SARC-F) and the Short Physical Performance Battery (SPPB). Mortality at 180 days was compared across these three frailty scores. Multivariable logistic regression was performed to estimate the association between frailty scores and 180-day mortality, after adjustment for age, gender, American Society of Anesthesiologists physical status classification system (ASA), surgical time, and surgical urgency.
resultsAmong 11,954 surgical patients aged ≥ 75, frailty scores were available in 250 to 500 patients depending on the tool. Pathological values of MNA, SARC-F, and SPPB were each associated with significantly increased 180-day mortality. After adjustment, MNA (aOR = 3.56, 95% confidence interval (CI) 1.64–7.72, p = 0.001), SARC-F (aOR = 2.03, 95% CI 1.19–3.46, p = 0.009), and SPPB (aOR = 2.63, 95% CI, 1.15–6.05, p = 0.023) remained independently associated with mortality.
conclusionMalnutrition and sarcopenia risk were significantly associated with increased mortality in surgical patients aged ≥ 75, independently of traditional risk scoring like ASA. These findings support the added value of frailty screening tools during preoperative assessment in older surgical patients.
