Abstract:
Objective To investigate the relationship of skin failure (SF) with nutritional status in elderly critically ill patients and analyze the predictive efficiency of nutritional status on SF. Methods A total of 340 elderly critically ill patients admitted to the hospital from January 2020 to January 2025 were selected as research subjects. According to whether skin failure occurred, the above patients were classified into skin failure group and non-skin failure group. The nutritional status indicators [serum albumin (ALB), prealbumin (PA), total protein (TP), hemoglobin (Hb), body mass index (BMI), nutritional risk score (NRS 2002)] were compared between both groups. Multivariate analysis was performed on statistically significant indicators, and ROC curve was applied to analyze the predictive value. Results Among the 340 elderly critically ill patients, 142 cases (41.76%) developed skin failure. The ALB, PA, TP, Hb and BMI in the skin failure group were lower than those in the non-skin failure group (P<0.05) while the NRS2002 score was higher (P<0.05). After logistic multivariate analysis, ALB, PA and Hb were independent influencing factors of skin failure (P<0.05). ROC curve analysis revealed that the predictive value of ALB (AUC=0.850, 95%CI: 0.808-0.888, Z=-3.707, P<0.001) was better than that of PA (AUC=0.770, 95%CI: 0.717-0.816, Z=-3.100, P=0.002) or Hb (AUC=0.773, 95%CI: 0.722-0.819, Z=-2.556, P=0.011). Conclusion The occurrence of skin failure in elderly critically ill patients is closely related to nutritional status. ALB, PA and Hb are independent risk factors of SF, and ALB has the best predictive efficiency on SF.
