Abstract:

Objective

To analyze the influencing factors of malnutrition in elderly patients with intracerebral hemorrhage after surgery.

Methods

A total of 124 elderly patients with intracerebral hemorrhage after surgery at Neurosurgery Department of the First People's Hospital of Zigong City from January 2022 to March 2023 were selected as the research subjects. According to the Global Leadership Malnutrition Initiative standards, the patients were divided into a non-malnutrition group and a malnutrition group. Multivariate Logistic regression analysis was used to identify influencing factors for postoperative malnutrition, and receiver operating characteristic (ROC) curves were plotted to determine the optimal cut-off values for evaluating the discriminatory ability of the variables for malnutrition.

Results

Among 124 elderly patients with intracerebral hemorrhage after surgery, there were 72 cases in the non-malnutrition group and 52 cases in the malnutrition group. The differences in age, OICH score, swallowing disorders, albumin, NLR, and total cholesterol between the two groups were statistically significant (P<0.05). Multivariate Logistic regression analysis showed that age, albumin, and NLR were independent influencing factors for malnutrition in elderly patients with intracerebral hemorrhage after surgery (P<0.05). ROC curve analysis showed that the area under the curve for predicting malnutrition in elderly patients with intracerebral hemorrhage after surgery based on age, albumin, and NLR was 0.743, 0.835, and 0.648, respectively. Among them, the predictive power of albumin was higher than that of age and NLR. When age≥72.5 years, albumin≤30.08 g/L, or NLR≥2.52, it suggests that elderly patients with intracerebral hemorrhage after surgery may have malnutrition.

Conclusions

Age, albumin, and NLR are independent influencing factors for malnutrition in elderly patients with intracerebral hemorrhage after surgery. Clinical attention should be paid to nutritional screening and early intervention for patients with advanced age (≥72.5 years), low albumin (≤30.08 g/L), and high NLR (≥2.52).
