Abstract
OBJECTIVE: We studied whether improper bag exchange predicts the first peritonitis episode in continuous ambulatory peritoneal dialysis (CAPD) patients. PATIENTS AND METHODS: Our single-center prospective observational study of 130 incident urban CAPD patients who started peritoneal dialysis (PD) between March 2005 and August 2008 aimed to determine the relationship between bag exchange procedures examined at the 6th month of PD and risk for a first peritonitis episode. All patients were followed until a first peritonitis episode, censoring, or the end of the study. RESULTS: These 130 patients experienced 22 first peritonitis episodes during the 14-month follow-up. During bag exchange evaluation, 51.5% of patients washed their hands improperly, 46.2% failed to check expiration date or bag leakage, and 11.5% forgot to wear a face mask and cap. Patients experiencing peritonitis were more likely to forget to wear a face mask and cap. In multivariate Cox regression model, not wearing a face mask and cap [hazard ratio (HR): 7.26; 95% confidence interval (CI): 2.6 to 20.1; p < 0.001] and having anemia (HR: 0.96; 95% CI: 0.94 to 0.99; p = 0.005) were independent risk factors for a first episode of peritonitis. CONCLUSIONS: Not wearing a face mask and cap and having anemia were independent risk factors for peritonitis. A further randomized control study needs to verify the correlation between improper bag exchange technique and peritonitis in PD patients.
