Aim: Patients play a crucial role in preventing peritoneal dialysis (PD)-related events, including peritonitis and fluid overload, as PD procedures are mainly carried out at home. We asked patients to submit a PD self-assessment sheet at each outpatient visit in our daily clinical practice and evaluated its usefulness for outcomes in patients initiating PD. Methods: This retrospective cohort study included patients who underwent PD catheter insertion between January 2008 and October 2018. The submission rate of a PD self-assessment sheet was calculated from medical records until PD cessation or study completion (October 2020). The association between the submission rate and technique survival was analysed. Results: Among the 105 recruited patients (78 men, 60.4 ± 12.2 years), 44 discontinued PD and transferred to haemodialysis during the study period. The follow-up was 52.3 (28.7–79.3) months, and the median submission rate was 78%. The log-rank test showed that technique survival was significantly better in patients with a submission rate ≥ 78% than those with a submission rate <78% (p =.006). The submission rate remained significantly associated with less technique failure (hazard ratio 0.88 per 10%, p =.002) by the Cox regression analysis adjusted for age, sex, Charlson comorbidity index, estimated glomerular filtration rate and geriatric nutritional risk index. Conclusion: The submission rate of a PD self-assessment sheet is useful as a predictor of technique survival in patients initiating PD. Instruction that increases submission may improve technique survival in PD patients.
