Hemodialysis has a major influence on the quality of life of chronic renal failure patients. Great attention is currently paid to the development of supporting programmes for this patient group. Aim of this study was to evaluate the quality of life in maintenance dialysis and to research the influence of various factors related to treatment and ESRD on quality of life, taking into account also the level of school instruction. Reduced functional abilities, as measured by the Sickness Impact Profile (SIP), and Functional Living Test (FLT), derived by Karnofsky Activity Scale were assessed; Hospital Anxiety and Depression Scale (HAD) and semistructured interviews, including a clinical grading of symptoms were considered vs. age, duration of dialysis, level of school instruction. The study was performed with 40 hemodialysis patients, aged 57.4 +/- 14.9 years (range 22-79), treated since at least three years. Significant (P < 0.05) independent correlates with higher SIP scores (greater disability) and Functional Living Test were lower educational level, and the score of Hospital Anxiety and Depression Scale (HAD). No correlation was found for any of the three scales vs. age and vs. dialytic age; no gender difference was observed. A greater care in considering Quality of Life questionnaires is warranted, especially for the severe interference of instruction level of patients on results. QALY (Quality Adjusted Life Years), used as a tool for decision-making in clinical and political subsets, can include critical bias that invalidate conclusion.
