Objective:
The aim of the study was to investigate the association between dialysis shift and subjective sleep quality in chronic haemodialyzed patients.
Design:
A cross-sectional observational study.
Participants And Methods:
A total of 206 haemodialyzed patients aged from 22 to 71 participated in this study. Participants were grouped into the morning-shift and other-shifts groups. Subjective sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). All participants also completed the Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI).
Results:
Dialysis shift significantly predicted the PSQI score with patients receiving morning-shift haemodialysis having better sleep quality (β=0.15, p=0.01). Other independent predictors of the PSQI score included depression (β=0.42, p<0.001), anxiety (β=0.38, p<0.001), and tea drinking (β=0.20, p0.001). Together these factors explained 48.2% of the variance in the PSQI score.
Conclusion:
Morning dialysis shift was significantly associated with better subjective sleep quality in chronic haemodialyzed patients after adjusting for other confounders.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
