Depression Screening Tools for Patients with Kidney Failure: A Systematic Review

Area of Science:

• Nephrology
• Psychiatry
• Diagnostic Accuracy

Background:

• Patients with kidney failure exhibit higher depression prevalence than the general population.
• Routine depression screening is mandated for these patients by the Centers for Medicare and Medicaid Services' ESRD Quality Incentive Program.
• There is a lack of clear guidance on effective depression screening tools for this demographic.

Purpose of the Study:

• To systematically review the diagnostic accuracy of depression assessment tools used in patients with kidney failure.
• To identify well-validated and practical screening instruments for depression in this population.

Main Methods:

• A systematic literature search was conducted across major databases (MEDLINE, PsycINFO) up to June 2020.
• Included studies compared depression assessment tools against clinical interviews or other validated measures.
• Data on sensitivity, specificity, predictive values, and area under the curve were extracted, with risk of bias assessed.

Main Results:

• Sixteen studies evaluated depression screening tools for kidney failure patients.
• The Beck Depression Inventory II was the most frequently studied tool.
• Public domain tools like the Patient Health Questionnaire 9 and Geriatric Depression Scale 15 showed promise but require more research.

Conclusions:

• Existing research on the diagnostic accuracy of depression screening tools for kidney failure patients is limited and may lack generalizability.
• Methodological quality and reporting in current studies are often insufficient.
• Future research should focus on widely available and free tools, such as the Patient Health Questionnaire 2 and 9.
