To prevent peritoneal dialysis (PD)-related infection, components of self-catheter care have been emphasized. However, studies on the effectiveness of home recording for the prevention of PD-related infections are limited. This study aimed to examine the association between keeping home records of catheter exit site and incidence of PD-related infections.


Home record books were submitted by patients undergoing PD. The proportion of days on which exit-site home recording was carried out for 120 days (0–100%) was obtained. The patients were divided into the frequent home recording group (≥ 40.5%; median value) and the infrequent home recording group (< 40.5%). The associations between the recording group and the incidence rate ratios (IRRs) of PD-related infections were estimated via negative binomial regression models.


A total of 67 patients participated in this study (mean age, 66.7 years). The incidence rates for exit-site infection, tunnel infection, and peritonitis were 0.42, 0.22, and 0.06 times/patient-year, respectively. The IRRs of the frequent versus infrequent home recording groups for PD-related infection were 1.58 (95% confidence interval [CI], 0.72–3.46) in the univariate analysis and 1.49 (95% CI, 0.65–3.42) in the multivariate analysis. The IRRs of the frequent versus infrequent home recording groups for composite of surgery to create a new exit site and removal of PD catheter were 0.55 (95% CI, 0.78–3.88) and 0.35 (95% CI, 0.06–1.99), respectively.


This study could not prove that keeping home records of patients’ catheter exit site is associated with a lower incidence of PD-related infections.
