Association Between Individualized Education for Kidney Replacement Therapy Modality Selection and Peritoneal Dialysis Initiation: A Cross‐Sectional Study

INTRODUCTION: Peritoneal dialysis (PD) is an established home-based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD. METHODS: In this retrospective cross-sectional study, 175 patients who initiated maintenance hemodialysis or PD between April 2021 and September 2024 were classified by attendance at a dedicated KRT modality selection clinic. Logistic regression and propensity score matching were performed. RESULTS: Among 175 patients, 40 attended the clinic. PD was initiated in 35.0% of attendees compared with 10.4% of nonattendees. Clinic attendance was independently associated with PD initiation (adjusted odds ratio, 4.51; 95% confidence interval, 1.89-10.77; p < 0.001), and this association remained significant after matching. CONCLUSIONS: Individualized education in a dedicated outpatient clinic was associated with a higher likelihood of PD initiation.
