Abstract
AIM: To analyze the relationship between routine laboratory results and death risk in patients with cirrhotic esophageal variceal bleeding (CEVB), and to create a simple and timely predictive model of death for the patients.
METHODS: The medical documents of CEVB patients were reviewed retrospectively and the data were collected. Univariate and multivariate Logistic regression analyses were performed, in which the discharged results (survival or death) as dependent variables and the results of liver function, kidney function, serum electrolytes and blood cell analysis as independent variables were included. The multivariate regression equation was as the model for the prediction of patient outcome and its predictive performance was evaluated.
RESULTS: In univariate regression, the significant positive variables for death outcome were DBIL, AKP, K, WBC, PLT, and the negative variables were TP, AP, A/G, Na, Cl, Ca. The variables entered the multivariate regression included ALT, TBIL, DBIL, GP, A/G, Cr, Na, Cl, Ca, WBC, Hb, PLT. The sensitivity, specificity and accuracy of the regression equation for predicting death of CEVB patients were 97.1%, 95.1% and 95.8%.
CONCLUSION: The liver function, kidney function, serum electrolytes and blood cell count are generally independent factors for death risk of CEVB patients, especially DBIL, A/G and Ca. The created regression model shows good prediction performance.
