Background and Objectives: Primary care physicians (PCPS) are increasingly responsible for managing mental health, which can involve assessment and management of a psychiatric crisis. Psychiatric crises can include acute suicidal or homicidal ideation and capacity-impairing psychosis. Evidence suggests PCPs do not consistently assess or manage psychiatric crises and it is unclear how to train PCPs to address these potentially lethal scenarios. The main objective was to increase PCP resident confidence in assessing and managing a range of psychiatric crises. Methods: In a family medicine residency program that trains PCPs, we developed a three, 1-h didactic series and point-of-care reference documents. The curriculum focused on screening, outpatient management, inpatient criteria, logistics of voluntary and involuntary admission, and legal considerations. Resident confidence was measured by questionnaire before and 3 months after curriculum completion. Results: Prior to training, residents did not feel confident in assessing and managing psychiatric crises, except a slight majority (62%) in screening for suicidal and homicidal ideation. Resident confidence significantly increased for every aspect of assessing and managing psychiatric crises after the training (all P-values < .05), with the largest improvements for further assessing hallucinations, delusions, and suicidal and homicidal ideation. Conclusions: As PCPs increasingly manage mental illness, they will encounter a range of psychiatric crises in clinic. This study demonstrates that a brief training intervention and point-of-care resources can significantly increase PCP confidence to assess and manage these urgent, dangerous scenarios.
