Quality of life in chronic dialysis patients. Factors unrelated to dialysis modality.

The quality of life (medical, psychological, and social adaptation) of 66 chronic dialysis patients was studied cross-sectionally. The participants had similar levels of medical, psychological, and social adaptation to those found in previous studies of chronic dialysis patients. Medical, psychological, and social adaptation are independent dimensions that are only weakly intercorrelated. When categorized by specific individual or treatment characteristics, men and those over age 51 had poorer medical and psychological adaptation than did women and younger dialysis patients. Duration of dialysis was not related to quality of life. Vocationally active as compared to vocationally inactive subjects had generally superior medical, psychological, and social adaptation. Male sex, age over 51, and vocational inactivity are all associated with poorer dialysis patient adaptation. The development of profiles of groups of dialysis patients at increased risk for poor adaptation may help in targetting scarce psychosocial intervention resources. Studies of the psychosocial efficacy of differing treatment modalities need to consider non--treatment-related factors that may affect patient psychosocial outcomes.
