Occult Suicidality and Psychiatric Disease Among Emergency Department Patients with Low-acuity Chief Complaints

INTRODUCTION: Patients presenting to emergency departments (ED) are often screened for suicidality, even when their chief complaint does not involve mental health concerns. Patient receptiveness to ED-based mental health screening and intervention is unknown, particularly among patients with low-acuity chief complaints, who often prioritize rapid evaluation and discharge. METHODS: This cross-sectional study included adults with low-acuity chief complaints presenting to an urban, academic ED in the Northeastern United States during daytime and evening hours, from 2015 to 2016. Participants completed validated mental health screening instruments, including the Suicide Behaviors Questionnaire-Revised and the Patient Health Questionnaire-4. Participants were also asked to rate the importance of addressing mental health concerns during their ED visit. RESULTS: We approached 1,688 patients, and 816 (48.4%) consented to participate in the study. Of these, 27% screened positive for anxiety and 25% screened positive for depression. Even among patients with no prior depression history, 17% were at high risk of depression. Eleven percent of participants were at high risk for suicidal behavior, including 5% of those with no reported history of depression or bipolar disorder. Thirty-five percent of patients at risk for suicide and 53% of those at high risk of depression thought it was important or very important to address these issues during the ED visit. CONCLUSION: Symptoms of mental health disorders were common among this group of ED patients presenting with low-acuity chief complaints. Patients often desired to address these mental health concerns as part of their ED visit.
