Systems Approach to Suicide Prevention: Strengthening Culture, Practice, and Education.

Contemporary approaches to suicide prevention extend beyond an individual's interactions with care providers to seek opportunities for improvement in the wider care system. A systems-based analysis can yield opportunities to improve prevention and recovery across the care continuum. This article uses an example of an individual seeking care in an emergency department to show how a traditional clinical case formulation can be framed in terms of the outer and inner contexts of the EPIS (Exploration, Preparation, Implementation, Sustainment) framework to illuminate the impact of systemic factors on outcomes and to identify opportunities for improvement. Three mutually reinforcing domains (a culture of safety and prevention; best practices, policies, and pathways; and workforce education and development) of a systems approach to suicide prevention are outlined, along with their defining characteristics. A culture of safety and prevention requires engaged, informed leaders who prioritize prevention; lived experience integrated into leadership teams; and adverse events review in a Restorative Just Culture focused on healing and improvement. Best practices, policies, and pathways that promote safety, recovery, and health require codesign of processes and services and evolve through continuous measurement and improvement. To support a culture of safety and prevention, and caring, competent application of policy, organizations benefit from a longitudinal approach to workforce education. This includes a common framework and language; models clinical and lived experience collaboration; and supports continuous learning, as well as onboarding of new staff, rather than following a "one-and-done" approach, so that suicide prevention training remains top of mind across the workforce.
