Analysis of prognostic evaluation value of prognostic nutrition index in elderly patients with cerebral apoplexy / 中国实用护理杂志

ABSTRACT

Objective:To explore the prognostic evaluation value and influencing factors of prognostic nutritional index (PNI) in elderly patients with stroke, and to analyze the value of PNI as an indicator of stroke outcome and prognosis.Methods:The clinical data of 356 elderly patients with cerebral apoplexy treated in hospital from December 2015 to June 2019 were analyzed retrospectively. According to PNI index, there were 154 cases of PNI≥45 and 154 cases of PNI.Results:General data showed that patients with PNI < 45 had higher age, body mass index (BMI), TP, ALB, lymph, TG, Glu, BMI and Mrs scores than those with PNI≥45, The difference was statistically significant ( χ2 values were 0.005-0.083, t values were 0.037-1.455, P<0.05). The results of multivariate analysis showed that PNI ( HR value was 1.43, 95% CI 0.94-2.25 , P<0.01, standardized partial regression coefficient was 0.051) had the highest contribution and was an independent risk factor for prediction of postoperative risk. Moreover, kappa coefficient indicated that PNI was consistent with MRS ( P<0.01). Conclusions:PNI is an independent factor affecting the prognosis of elderly patients with CS, which is of great significance to the evaluation of prognosis and analysis of influencing factors in elderly patients with CS.
