Official title

A System of Safety: Preventing Suicided Through Healthcare System Transformation

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

SOS will identify evidence based best practices consistent with Zero Suicide's six specific recommended clinical actions (A.2.) and use them to develop standardized clinical protocols for each care setting, clinical unit, population serviced, and clinical discipline. Using Lean CQI, the investigators will tailor, implement, and improve adherence to these protocols. To support feasibility, SOS will use a phased roll out and a hub-and-spoke design. The intervention targets will be suicide-related clinician behaviors. The investigators will aspire to adopt best practices and measure all six recommended performance elements; however, for feasibility, the research evaluation will focus on suicide risk screening, safety planning, means restriction counseling, and post-acute care follow-up calls. The primary patient outcomes will be suicide risk identification, suicide, suicide attempts, and suicide-related emergencies requiring acute care. The investigators will examine potential mechanisms of action and moderators, and conduct a cost effectiveness analysis of SOS versus usual care. The investigators will employ a stepped wedge design and follow individuals for 6 to 54 months. Outcomes, clinician behaviors, and other variables will be gathered through: (1) EHR data extraction, (2) claims data from UMMHC and the MA All Payer Claims Database, (3) random medical chart abstractions, (4) MA state vital statistics and National Death Index (NDI), (5) clinician surveys, (6) Lean evaluations and process observations, and (7) patient fidelity interviews. Data will be analyzed using generalized linear mixed models.
