Quality of sleep and health‐related quality of life in haemodialysis patients

Background. Sleep complaints are common in haemodialysis patients. In the general population, insomnia impacts negatively on health‐related quality of life (HRQoL). The objective of this study was to examine the association between quality of sleep and HRQoL in haemodialysis patients independent of known predictors of HRQoL. Methods. Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI) and HRQoL was measured using the Medical Outcomes Study 36‐item Short Form (SF‐36) in 89 haemodialysis patients. Results. Sixty‐three (71%) subjects were ‘poor sleepers' (global PSQI >5). The SF‐36 mental component summary (MCS) and physical component summary (PCS) correlated inversely with the global PSQI score (MCS, r=−0.28, P
