Who Have a Better-kidney-related Quality of Life: Peritoneal Dialysis or Hemodialysis Patients? A Cross Sectional Study from Saudi Arabia

Background: End-stage kidney disease (ESKD) substantially impacts different aspects of patients' lives, including mental and physical health, and overall quality of life. The aim of our study is to assess the quality of life (QoL) and the associated predictors in ESKD Saudi Arabian patients receiving either hemodialysis (HD) or peritoneal dialysis (PD). Saudi Ministry of health (MOH) is advancing dialysis care in the country with more focus on patients' satisfaction and QoL. However, the data regarding QoL in Saudi Arabian dialysis patients is limited.

Methods: A cross sectional study was carried out using Kidney Disease Quality of Life scale (KDQOL-36) to assess the QoL. We disturbed a validated formal arabic version of the questionnaire. Patients older than 18-year-old and attending dialysis clinics in Aseer region, Saudi Arabia, were invited to participate in the study.

Results: A total of 152 responses were analyzed, which were separated into two primary groups: the HD group (98 patients) and the PD group (54 patients). Our results showed no significant differences between the two groups except for the KDQOL-SF-36 physical composite score at which the PD group had a higher mean than the HD group 44.75 vs 37.84, respectively (p < 0.001). However, more PD patients reported feeling depressed compared to HD patients.

Conclusions: Kidney Disease Quality of Life scale scores were comparable between HD and PD groups except for the physical composite score. On the other hand, PD patients tend to suffer from depression more than HD patients. Interventions to attenuate the physical deconditioning and depressive symptoms in HD and PD patients, respectively, are crucial. Future prospective studies with larger sample sizes are warranted.
