Depression in hemodialysis patients.

Psychiatric evaluation of depression in medically ill patients using DSM-III-R or Research Diagnostic Criteria (RDC) is difficult because these diagnostic systems have not been validated for this population. Diagnosis of depression has been especially problematic in patients with end-stage renal disease (ESRD). This study found a 17.7% prevalence of RDC-defined minor depression and a 6.5% prevalence of major depression in 124 ESRD patients treated with hemodialysis. Vegetative symptoms of depression were less useful for discriminating between those with and without depression than were the psychological symptoms of suicidal ideation, depressed mood, and discouragement.
