SUMMARY Background Sleep disorders and depression are prevalent conditions in patients with end‐stage kidney disease. These co‐morbidities have significant overlap and compounded morbidity and mortality burden. This overlap presents challenges to optimal clinical assessment and treatment. The goal of this study was to assess the prevalence of sleep disturbance in patients on maintenance haemodialysis, and to assess the impact of depressive affect. Objectives This was a single‐site, single group, cross‐sectional study of 69 English‐speaking patients undergoing maintenance haemodialysis. Self‐reported assessments included those of sleep quality (Pittsburgh Sleep Quality Index), depression (Beck Depression Inventory), daytime sleepiness (Epworth's Sleepiness Scale), a dialysis‐specific sleep questionnaire, and standard laboratory values. No objective sleep information was collected. Method All participants were well dialysed, and represented all four daily shifts. Fifty‐eight per cent reported clinically significant sleep difficulty, with elevated yet sub‐threshold daytime sleepiness. Mean depressive affect was also elevated, yet sub‐diagnostic and was positively correlated with increased age. Results Participants scoring above the diagnostic threshold for depression had significantly more disturbed sleep quality, more daytime sleepiness and had more problems sleeping due to restless leg syndrome than people with minimal depressive affect. Conclusion Poor sleep quality is prevalent in patients on maintenance haemodialysis, and is associated with increased daytime sleepiness. Depression further compounds this relationship, and is significantly associated with increased daytime sleepiness and restless leg syndrome.
