A New Risk Score for Predicting 1-year Mortality in Older r Maintenance Hemodialysis Patients.

The goal of this retrospective observational cohort study is to analysis the 1-year mortality in older patients undergoing maintenance hemodialysis. The main question it aims to answer is to explore the risk factors affecting the mortality of older patients undergoing maintenance hemodialysis and establish a risk prediction score.

Data of older patients (age ≥65 years old) undergoing maintenance hemodialysis were collected from 2012-1-December 31, 2014, with data from Beijing Blood Purification Quality Control and Improvement Center (BJHDQCIC). Logistic regression model was used to evaluate the 1-year mortality and the influence of predictive factors. Internal validation of the model was performed using the bootstrap 1000 repeat sampling method. Area under receiver operating characteristic curve (AUC) was used to evaluate the predictive ability of the model.
