Sexual assault nurse examiners (SANEs) provide specialized medical forensic care to survivors of sexual assault, often working in stressful conditions, with routine exposure to the traumatic experiences of their patients. SANEs experience high levels of both vicarious trauma and burnout. The purpose of this article was to describe the development of a SANE support application, accessible to all SANEs, that utilizes self-care and positive coping strategies to enhance SANE resilience and thereby reduce burnout. The conceptual framework for the SANE support application was psychological first aid, an evidence-informed, manualized intervention to assist individuals in the immediate aftermath of exposure to potentially traumatic events. Focus groups with SANEs informed the content of the application named "SANE Well." SANE Well delivers these helpful coping elements within an easy-to-use, mobile platform, at no cost. User testing during two SANE clinical skills laboratory trainings revealed the app had smooth and efficient functionality and meets its intended goals without unnecessary complexities. There is an urgent need for SANEs to protect their well-being while they care for individuals who have experienced sexual assault. The SANE Well application offers a novel way to provide and encourage positive coping strategies for nurses to reduce burnout.
