Key result
A WHOQOL-BREF physical or psychological domain score of ≤10 was associated with an approximately 2.3- and 2-fold increase in 10-year mortality among hemodialysis patients, respectively.
Why the study?
Previous studies linking quality of life to mortality in hemodialysis relied mainly on complex tools like the SF-36, prompting the need to assess this impact using an easier and simpler instrument.

Does quality of life measured by WHOQOL-BREF predict mortality in maintenance hemodialysis patients?
Effect estimate: 2.3-fold (physical) and 2-fold (psychological) increase
Lower quality of life scores in physical and psychological domains on the WHOQOL-BREF are associated with a 2- to 2.3-fold increase in 10-year mortality among hemodialysis patients.
Kim et al. (2022) conducted a cross-sectional in Maintenance hemodialysis (n=160). Low quality of life (WHOQOL-BREF physical or psychological score ≤10) vs. Higher quality of life scores was evaluated on 10-year mortality rate (2.3-fold (physical) and 2-fold (psychological) increase). A WHOQOL-BREF physical or psychological domain score of ≤10 was associated with an approximately 2.3- and 2-fold increase in 10-year mortality among hemodialysis patients, respectively.
