title: Health-related quality of life in patients on peritoneal dialysis in Serbia: comparison with hemodialysis.
abstract: Patients' health-related quality of life (HRQoL) is an important indicator of the effectiveness of the medical care they receive. Patients who reach end-stage renal disease are older and have a considerable extent of comorbidity. The objectives of this study were (i) to evaluate HRQoL in patients at the initiation of continuous ambulatory peritoneal dialysis (CAPD) treatment (incident cohort) and in patients on long-term CAPD therapy (prevalent cohort), and (ii) to compare influence of comorbidity on HRQoL in CAPD and hemodialysis (HD) patients. In a cross-sectional study we enrolled 99 CAPD and 192 HD patients. HRQoL was assessed with the 36-item Short Form Health Survey Questionnaire (SF-36). HRQoL summary scales in both incident and prevalent groups of CAPD patients were similar for physical component summary score (PCS) and for mental component summary score (MCS). Generally, higher values were found in mental health domains in comparison to PCS. In the incident group of patients, 1 year of peritoneal dialysis treatment was associated with a slight improvement in both PCS and MCS, but statistical significance (P < 0.05) was found in the role-physical limitation (RP), bodily pain (BP), and vitality (VT) scales only. CAPD patients with the highest disease severity (Index of Disease Severity [IDS]-3) and physical impairment (Index of Physical Impairment [IPI]-2) scored significantly higher parameters of HRQoL than HD patients. Comorbidity had negative influence on HRQoL, but statistically significant correlation has been found in HD patients only. In conclusion, comorbid conditions had negative correlation with parameters of HRQoL in both CAPD and HD patients. One year after starting CAPD, patients reported better scores in some domains, especially in RP, BP, and VT scales. Assessment of HRQoL and comorbidity might be useful in clinical practice in the follow-up of patients treated with both CAPD and HD.
