  1. Differences in quality of life among patients receiving dialysis replacement therapy at seven medical centers.

    Article - En anglais

    The purpose of this study is to investigate the variations in qualiry of life (QOL) among patients with end-stage renal disease (ESRD) who are receiving replacement therapy in several dialysis centers.

    This observational study includes interviews with nurses and data extraction from medical charts for all 680 adults who had been on dialysis therapy for more than 4 weeks in seven dialysis centers.

    By using multivariate analysis, we generated a model to explain the variance in QOL as measured by the QL index score (developed by Spitzer et al., J Chronic Dis 1981 ; 34 : 585-597) among patients pooled from all centers.

    The expected mean QL index score and 95% confidence interval were computed for each dialysis center.

    Centers with observed mean QL index scores outside of the expected confidence range were marked as possible outliers.

    We found the following patient attributes to be independently associated with QOL : age, education, occupation, and certain comorbidities (e.g., diabetes, stroke).

    After adjustment for case mix, we could identify four outlier centers.

    After further adjustment for albumin in serum, a possible process indicator, two centers were no longer considered as outliers.

    These findings indicate that the variance in QOL of ESRD patients at different centers is not entirely explained by known case-mix factors.

    Further research should explore whether such variations are related to dissimilarity in the process of care at different centers.
