Objective: To assess and compare the quality of life of patients treated with haemodialysis and chronic ambulatory peritoneal dialysis (CAPD) in Utrecht and Willemstad, Curaçao.
Design: Transverse multicentre study.
Methods: All haemodialysis and CAPD patients in Utrecht and all haemodialysis patients in Curaçao under treatment for over 6 months were studied. The objective tests applied were the 'Nottingham health profile', the 'affect balance scale', the 'index of well-being' and the 'Amsterdam complaint profile'. Possible correlations between individual patient-related and treatment-related factors and biochemical variables were also investigated.
Results: The objective and subjective tests revealed only slight differences in quality of life in the three groups. In a few respects, the CAPD patients rated the quality of life slightly better. In the Utrecht group a positive relationship was seen between haematocrit (higher owing to treatment with erythropoietin) and plasma bicarbonate concentration, and the quality of life.
