Review of EmPATH Units for Behavioral Health Casualties in Prolonged Field Care Environments.

Introduction: Psychiatric conditions are one of the leading non-battle injury diseases resulting in medical evacuation (MEDEVAC) from combat environments. The challenge of limited MEDEVAC capability necessitating prolonged field care in future large-scale combat operations must be addressed. Therefore, a robust program is needed to address frontline care of behavioral health (BH), maximizing service members returning to duty and minimizing MEDEVAC. This review summarizes the literature on the impacts of the Emergency Psychiatric Assessment, Treatment, and Healing (EmPATH) Unit program as a solution to the challenges of treating behavioral health in future wars.

Materials And Methods: We conducted a systematic literature search and review, and a non-systematic literature critique. We then used the Johns Hopkins evidence appraisal tool to appraise the strength and quality of the evidence. The following electronic databases were utilized for the search: Google Scholar, Embase, CINAHL, and PubMed. Search terms included: included "EmPATH," "prolonged field care," and "operational," alone and combined.

Results: The literature review found that the EmPATH unit, a recently developed civilian hospital-based program, can work with higher acuity psychiatric crisis patients who would otherwise be admitted to an inpatient unit, showing promising results in avoiding the need for inpatient hospitalization. EmPATH units help decrease hospitalization rates, reduce restraints and violence, and shorten the patients' boarding time in a holding area. Such findings support the use of the EmPATH unit as a tactic for prolonged field care of psychiatric patients in a combat operational environment.

Conclusions: This is the first literature review to consider EmPATH units for psychiatric prolonged field care based on its advantages demonstrated in the civilian sector. Studies have yet to be done on EmPATH units' usefulness in the military, showing a knowledge gap in current evidence supporting its suitability. Thus, this review recommends further studies of EmPATH units in military settings, especially prolonged field care environments.
