Background: "Gold standard" methods for muscle mass (MM) assessment are expensive and difficult to use in clinical practice. The present study aimed to evaluate the association between easy‐to‐apply and low‐cost indicators of MM and clinical outcomes in hospitalized patients. Methods: In this cohort study, calf circumference [CC], adductor pollicis muscle thickness [APMT], midarm muscle circumference [MAMC], and arm muscle area [AMA] were measured within 48 h of admission to detect MM loss, and it was also evaluated by physical examination. Patients were followed up until discharge for collection of in‐hospital death and length of hospital stay (LOS) data, and they were contacted by phone to assess hospital readmission and mortality at 6 months after discharge. Results: We evaluated 601 patients (55.8 ± 14.8 years). Moderate/severe loss of MM (hazard ratio [HR], 4.12; 95% CI, 1.26–13.49), low CC (HR, 3.67; 95% CI: 1.07–12.55), low MAMC (HR, 5.20; 95% CI, 1.48–18.35), and low AMA (HR, 14.28; 95% CI, 1.80–113.14) were predictors of in‐hospital mortality. Moderate/severe loss of MM was a predictor of prolonged LOS (odds ratio [OR], 2.27; 95% CI, 1.53–3.36), hospital readmission (OR, 4.14; 95% CI, 1.26–13.55), and mortality at 6 months (OR, 3.20; 95% CI, 1.71–6.01). Low CC (OR, 2.49; 95% CI, 1.27–4.85) and low APMT (OR, 3.22; 95% CI, 1.56–6.66) were associated with death 6 months after discharge. Conclusion: Easy‐to‐apply and low‐cost indicators of MM were associated with negative clinical outcomes and should be part of nutrition assessment in hospitals [ABSTRACT FROM AUTHOR] |
