Handgrip strength: Best practice for a rapid nutrition screening and risk stratification in male patients with alcoholic liver cirrhosis, a classification and regression tree analysis study

Background Rapid nutrition screening (NS) is vital for apt management in patients with alcoholic liver cirrhosis (ALC). Aim To identify a quick method of NS having high reliability and prognostic significance. Methods NS of patients with ALC was assessed using mid‐upper arm circumference (MUAC), handgrip strength (HGS), fat‐free mass index (FFMI), and the Royal Free Hospital‐Global Assessment (RFH‐GA). Baseline clinical and biochemical information were recorded along with 90‐day survival data. The classification and regression tree method was used to classify HGS, MUAC, and FFMI values as well nourished (WN), moderately malnourished (MM), and severely malnourished (SM), and their concordance with RFH‐GA categories was assessed using Kendall tau‐b coefficient. The prognostic proficiency of each method was tested by Cox regression analysis. Results According to the RFH‐GA, of 140 male patients with ALC, 13 of 140 (9.3%) were WN, 93 of 140 (66.4%) were MM, and 34 of 140 (26.8%) were SM. HGS has the strongest association with the RFH‐GA (Kendall tau‐b = 0.772; diagnostic accuracy −81.4%). HGS was found to be the independent predictor of 90‐day mortality (26 of 140 [18.6%]; hazard ratio, 0.93; 95% CI, 0.88–0.98; P = 0.002) after adjusting for age, body mass index, and disease severity. The hazard of mortality was 8.5‐times higher in patients with ALC with HGS 29. Conclusion HGS is a reliable tool for rapid NS. HGS
