Relationship between psychological well-being and perception of quality of life in hemodialysis patients

Abstract

Introduction: Hemodialysis is the most widely used therapeutic alternative in patients with chronic kidney disease; however, the conditions of psychological well-being and quality of life of these patients have not been established in a multidimensional way. Objective: To analyse the profile of psychological well-being and perception of quality of life of hemodialysis patients, as well as to differentiate and identify the relationship between these variables. Material and method: Cross-sectional descriptive observational study carried out on 173 hemodialysis patients. The PGW-BI questionnaires were used to assess psychological well-be-ing and the WHOQOL-BREF for quality of life. Results: Patients with CKD on hemodialysis with an average age of 57.59±13.31 years, predominantly male (n=110; 63.58%). High indices of psychological well-being (78.61%) and moderate perceptions of quality of life (54.91%) were found, accompanied by depressive (97.11%) and anxious (97.11%) symptomatology. Age, educational level, employment status, income, having diabetes mellitus and inadequate blood concentrations of haemoglobin, potassium and phosphorus showed differences in the domains and categories (p<0.01). Correlational analysis found a strong linear relationship between the two variables studied (r=0.81; p=0.0001). Conclusions: Study participants showed high perceptions of psychological well-being and moderate appreciations of quality of life at the expense of high ratings of positivity, self-con-trol, vitality and perceptions of physical health, psychological health and social relationships. Psychological well-being according to different categories directly influences the perceived quality of life of hemodialysis patients.
