Comparison of pre- and post-hemodialysis PHQ-9 depression scores in patients with end-stage renal disease: A cross-sectional study.

Our study supports the fact that the prevalence of depression is high among patients with ESRD on maintenance hemodialysis. We didn't find a significant difference in depression scores among hemodialysis patients before and after dialysis, with negligible effect of uremic symptoms on the diagnosis of depression. We suggest adopting routine screening of depression among this high-risk group of patients.
