Kidney Disease–Specific Scores and Health Utility of Continuous Ambulatory Peritoneal Dialysis Patients, Automated Peritoneal Dialysis Patients, and Caregivers

Abstract

© 2020 ISPOR–The professional society for health economics and outcomes research Objectives: This study aimed to compare the EuroQol 5-dimension 5-level questionnaire (EQ-5D-5L), the visual analogue scale (VAS), and the Kidney Disease Quality of Life 36-Item Short-Form Survey (KDQOL-36) scores of Thai continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) patients and to compare the utility scores with the EQ-5D-5L and VAS scores of caregivers. Methods: This was a cross-sectional study completed between April 2016 and May 2017. In total, 34 CAPD patients, 30 APD patients, and their caregivers were recruited from a large university hospital in Thailand. A trained interviewer conducted face-to-face interviews. We collected demographic data and used the KDQOL-36 and EuroQol questionnaires (EQ-5D-5L and VAS) to assess the health-related quality of life. Caregivers were asked to assess their own health status using the EQ-5D-5L and VAS. Results: The EQ-5D-5L and VAS responses of the CAPD and APD patients and their caregivers were not significantly different (P >. 05). More than 50% of both patient groups had mobility problems, whereas most patients had no problems with self-care, doing usual activities, pain or discomfort, and anxiety or depression. As for the KDQOL-36, the physical and mental component summaries were not significantly different, and neither were the scores for all of the kidney disease-specific dimensions, including symptoms or problems, effects of kidney disease, and burden of kidney disease (all were P >. 05). Conclusions: The results indicated that the quality of life of CAPD and APD patients and their caregivers were mostly equivalent. A further longitudinal study of utility score assessments of the differences in modality would be advantageous.
