Suicidal ideation is insensitive to suicide risk after emergency department discharge: Performance characteristics of the Columbia-Suicide Severity Rating Scale Screener.

The C-SSRS screener is insensitive to suicide risk after ED discharge. Most patients who died by suicide screened negative and did not receive psychiatric services in the ED. Moreover, most patients with suicidal ideation died by causes other than suicide. The screener was more sensitive for predicting nonfatal self-harm and may inform a comprehensive risk assessment. These results compel us to reimagine the provision of emergency psychiatric services.
