Objective Emergency department ( ED ) patients with psychiatric chief complaints undergo medical screening to rule out underlying or comorbid medical illnesses prior to transfer to a psychiatric facility. This systematic review attempts to determine the clinical utility of protocolized laboratory screening for the streamlined medical clearance of ED psychiatric patients by determining the clinical significance of individual laboratory results. Methods We searched PubMed, Embase, and Scopus using the search terms “emergency department, psychiatry, diagnostic tests, laboratories, studies, testing, screening, and clearance” up to June 2017 for studies on adult psychiatric patients. This systematic review follows the recommendations of Meta‐analysis of Observational Studies in Epidemiology ( MOOSE ) statement. The quality of each study was rated according to the Newcastle‐Ottawa quality assessment scale. Results Four independent reviewers identified 2,847 publications. We extracted data from three studies ( n = 629 patients). Included studies defined an abnormal test result as any laboratory result that falls out of the normal range. A laboratory test result was deemed as “clinically significant” only when patient disposition or treatment plan was changed because of that test result. Across the three studies the prevalence of clinically significant results were low (0.0%–0.4%). Conclusions The prevalence of clinically significant laboratory test results were low, suggesting that according to the available literature, routine laboratory testing does not significantly change patient disposition. Due to the paucity of available research on this subject, we could not determine the clinical utility of protocolized laboratory screening tests for medical clearance of psychiatric patients in the ED . Future research on the utility of routine laboratory testing is important in a move toward shared decision making and patient‐centered health care.
