Introduction: Behavioral health disorders are the leading category of evacuations from the U.S. Central Command (USCENTCOM) area of responsibility. Understanding the relative risk of behavioral health conditions associated with all-cause evacuation is important for the allocation of resources to reduce the evacuation burden.
Materials and methods: Data from the USTRANSCOM Regulating and Command & Control Evacuation System and Theater Medical Data Store covering personnel deployed to the USCENTCOM area of responsibility between January 1, 2017 and December 31, 2021 were collected and analyzed. All individuals who were diagnosed with a behavioral health-specific ICD-9 (290-316) or ICD-10 (F00-F99) code during the period were included. Using the earliest medical encounter, the number of individuals diagnosed with a particular code and the frequency individuals were evacuated being diagnosed with any code were calculated.
Results: The mean monthly USCENTCOM population during this period was 62,535. A total of 22,870 individuals were diagnosed with a behavioral health-related disorder during the study period. Of this population, 1,414 individuals required an evacuation. The relative risk of the top 30 diagnosis codes used during the initial visit of individuals during the study period was calculated. Within this group of initial diagnoses, F32.9 'Major depressive disorder, single episode, unspecified' had the highest proportion evacuated at 15.9%.
Conclusions: There is a broad array of behavioral health-specific diagnoses used initially in the care of behavioral health disorders with a great variation in their association with evacuation risk. Variations of diagnoses associated with anxiety, depressive, and adjustment disorders are most associated with eventual evacuation.
