Evolución de la calidad de vida en pacientes en hemodiálisis: Estudio prospectivo a un año

Abstract

Background. In a previous study we described how the quality of life (QL) in patients undergoing haemodialysis is lower compared to the general healthy population and that the depressive state and degree of comorbidity are the most significant QL determining factors. This study carries out a new assessment of the same patients after one year and studies the factors determining changes in QL level. Methods. All the patients studied one year earlier were included and underwent quality of life tests (SF-36) and psychological tests. The degree of comorbidity was recorded, as well as demographical data and morbidity events. Results. The series for analysis was made up of 52 patients, after excluding those who had received transplants and those who had died. Only the physical functionalism component was reduced significantly while the rest of the components did not vary. The degree of anxiety and depression does not show differences in an interval of one year. The value of the QL is determined to a significant extent by the state of depression, age and the degree of comorbidity. Taken together, these 3 variables account for 67% of the variability in the physical function domain.
