Shared Decision Making for Choosing renAl Replacement Therapy in Chronic Kidney Disease Patients

Shared decision making (SDM) is an approach where clinicians and patients make decisions together using the best available evidence. An understanding of the patient's treatment goals, the advantages and disadvantages of treatment options, and the likelihood of achieving the outcomes are important to patients. International guidelines recommend that all patients with chronic kidney disease (CKD) at pre-dialysis stage should be educated to improve their knowledge and understanding of their condition and to choose the options for renal replacement therapy (RRT). Despite these recommendations, pre-dialysis educations are often infrequent. Many patients feel unprepared. Wrong or insufficient understanding due to insufficient explanation of treatment can lead to negative emotions. This may lead to a situation in which the patient loses the opportunity to make patient's own choices, resulting in emergency dialysis or dialysis modality that is not suitable for patients. Therefore, this study aims to evaluate whether SDM has an effect on the choice of RRT among CKD patients.

Inclusion Criteria: * Patients with chronic kidney disease whose nephrologist predicts initiation of renal replacement therapy within 12 months: 1. Patients with grade 5 of chronic kidney disease \[defined as a creatinine-based estimated glomerular filtration rate (eGFR) \< 15 ml/dL/1.73m2 at least 2 times at intervals of 2 weeks or longer\] 2. Patients with the cystatin C-based eGFR \< 15 ml/dL/1.73m2 at least once if the creatinine-based eGFR does not accurately evaluate the kidney function of patient due to patient characteristics 3. Patients whose nephrologist require renal replacement therapy within 12 months due to the patient's comorbidities even when the eGFR is 15ml/dL/1.73m2 or higher * Patients aged between 19 and 80 years * Patients who understand the study * Patients who have no permanent access device for long-term maintenance dialysis Exclusion Criteria: * Patients who have contraindication to perform peritoneal dialysis due to abdominal surgery * Patients whose life expectancy is less than 6 months due to underlying diseases * Patients who have enrolled in other clinical trials within 3 months or plan to participate in other clinical trials during this clinical trial period * Patients judged by the investigator to be inappropriate for participation in this clinical trial
