Analysis of risk factors about patient withdrew from peritoneal dialysis

Abstract

Objective To investigate the risk factors for the dropout of peritoneal dialysis(PD), and then provide the foundation for improving survival rate of patients with end-stage renal failure. Methods Clinical data was collected from 196 PD patients in our hospital between January 2008 and December 2013. All patients were divided into two groups, dropout group and control group. The social condition, general information, clinical data and so on were collected. For example, the people who changed the extraneal, working condition, residual urine volume, as well as serum creatine were recorded. Univariate analysis and multivariate logistic regression analysis were used to analyze the risk factors for dropout. Results Univariate analysis showed that the place of residence, education level, working condition, people who changed the extraneal, residual urine volume, serum creatine, and eGFR impacted on the dropout. Multivariate logistic regression showed that working condtion, people who changed the extraneal, residual urine volume and serum creatine were independent factors. Residual urine volume was negatively correlated with dropout and serum creatine was positively correlated. Conclusions In our hospital, the main reason of the dropout of PD is the weaker residual urine volume. We should pay attention to patient education, find the appropriate timing to start PD, and encourage patients to take part in the work as well as change the extraneal by themselves.
