Health-Related Quality of Life in Hemodialysis Patients: An Iranian Multi-Center Study

Background: the effectiveness of health care and health policy developments are often determined by health-related quality of life (hrqol) assessment. objectives: the objective of this study was to explore the potential corresponding factors and traditional biomarkers of hrqol in a large number of iranian hemodialysis patients. patients and methods: a total of 6,930 chronic hemodialysis (hd) patients enrolled. kdcs-sf version 1.3 questionnaire was used to assess the health related quality of life (hrqol). we pooled pcs, mcs and kdcs scores with random effect model from 19 similar studies performed between 1996 and 2010 results: the mean age was 54.4 ± 17.1 years. mean pcs, mcs and kdcs scores obtained for the study cohort were 40.79 ± 20.10, 47.79 ± 18.31 and 57.97 ± 11.70, respectively; the total score of sf-36 plus kdcs was 51.12 ± 13.41 as well. the most common primary known disease was hypertension (31.9%) and the second etiology was diabetes (25.5%). in multilevel logistic regression, kt/v between 1 and 1.2 and pcs, kdcs more than 50 were considered as a significant reduction in the risk of hospitalization. conclusions: this study showed that pcs and mcs score were slightly more than overall results while kdcs was slightly less than overall results. in addition, dialysis adequacy with kt/v between 1 and 1.2 is associated with lower rate of hospitalization.
