Suicide risk and acute stress continue to remain top concerns for the U.S. military and Veteran populations. According to recent statistics, suicide is a top 10 cause of death among U.S. residents, and the second most common cause of death among those between 10 and 34 years old. Deaths by suicide have increased 30% from 1999-2016, with concomitant increases in DoD active-duty and veteran suicide rates. In addition to suicide risk, the potential risk for acute stress in military service-members is salient when considering the potential for exposure to significant stress and aversive events often associated with military operational settings. Given the unique stressors and psychological risks associated with the military, it is paramount to incorporate active efforts that enhance awareness and early interventions in operational settings to bolster individual health and unit readiness. This poster will detail how simulation is being used to train DoD and VA teams to recognize signs of distress, intervene to initiate critical actions, and connect those in crisis to appropriate advanced care. Further, simulation-based training can aid in self-surveillance and decrease stigma regarding utilization of behavioral health resources. Simulation-based training creates a safe learning environment to practice these concepts, interact with subject-matter experts, ask difficult questions, and dispel myths about suicide and acute stress. There is particular relevance in providing simulation training for front-line healthcare teams that will be providing direct care for deployed AD service-members and/or Veterans. The multifaceted roles of many DoD and VA dental staff who are healthcare professionals but also service members or veterans themselves present unique challenges. They may be both patients and colleagues in the healthcare systems in which they serve and their patients may also be their colleagues. This can make suicide risk and acute stress recognition and intervention more challenging. In an aim to reduce stigma and improve training that is often delivered didactically, simulation is used to bolster training for healthcare professionals to successfully recognize suicide risk warning signs and acute stress in order to intervene early and as necessary connect individuals to care. Giving learners the experience of working through suicide risk and acute stress recognition and intervention scenarios better prepares healthcare providers for when their ability to intervene matters most. Further, the unique structure of the joint-simulation training program facilitates increased collaboration and sharing of experiences and resources between organizations, mental health professionals, and active duty, reserve, veterans, and VA team members.
