Background: The health-related quality of life (HRQOL) of dialysis patients has not been well examined, especially in combination therapy with peritoneal dialysis and hemodialysis (PD+HD) patients. We compared the HRQOL of PD+HD patients with that of HD and PD patients. Methods: A multicenter, cross-sectional study was conducted on 36 PD+HD, 103 HD, and 90 PD patients in Japan who completed the Kidney Disease Quality of Life Short Form 36, version 1.3. HRQOL scores were summarized into physical- (PCS), mental- (MCS), role/social- (RCS), and kidney disease component summaries (KDCS). Results: Of the PD+HD patients, 31 (86%) transferred from PD and 5 (14%) transferred from HD. They had the longest dialysis vintage and the smallest urine volume. PCS, MCS, and KDCS HRQOL scores of PD+HD patients were comparable with those of HD and PD patients. However, the RCS score for PD+HD was significantly higher than that for HD ( p = 0.020) and comparable with that for PD. PD+HD and PD were associated with significantly higher RCS scores than HD after adjusting for age, gender, diabetic nephropathy, dialysis vintage, ischemic heart disease, and peripheral arterial disease. Conclusions: For RCS, HRQOL in PD+HD patients was better than that in HD and comparable with that in PD patients, whereas the PCS, MCS, and KDCS HRQOL scores of PD+HD patients were comparable with those of HD and PD patients.
