Implementing universal suicide screening in a large healthcare system's hospitals: rates of screening, suicide risk, and documentation of subsequent psychiatric care.

This study reported outcomes of standardized suicide screening using the Columbia-Suicide Severity Rating Scale among adults in 23 hospitals in a large health system in northern California between 7/1/2019 and 12/31/2020. Out of 595,915 patients seen in hospital inpatient or emergency departments, 84.5% were screened and among them 2.2% had suicide risk, 41.3% of whom had a diagnosis of Major Depressive Disorder. Compared to patients without suicide risk, a higher proportion of patients who screened positive for suicide risk were male, Non-Hispanic White, younger, recently homeless, and had co-occurring mental health diagnoses. Overall, 52.5% of those screening positive for suicide risk had documentation of subsequent psychiatric care within the health system within 90 days and this rate was even higher (73%) for individuals whose screenings indicated the highest risk. These findings reinforce the need for increased screening, and research to determine whether screening leads to improved care and fewer suicides.
