Strategic Aeromedical Evacuations of the French Armed Forces in French Guiana From 2018 to 2020

The French Armed Forces are deployed in French Guiana (FG) to protect national territory and ensure the security of strategically important sites. Military health support (MHS) provides medical support for missions in this tropical environment, which is hazardous and where confrontations are possible. MHS must organize tactical and strategic evacuations (Strat-AEs), so that an optimal level of care can be delivered. Overall, Strat-AE activity has been described previously but no specific data related to FG has been reported. The main objective of this study was to provide an overview of military Strat-AEs from FG.

We conducted a retrospective cohort study from January 01, 2018 through 31 December, 2020. All patients who required a military Strat-AE were included, and we collected sociodemographic characteristics, medical information, service-related injuries and illnesses, and the reason for and conditions of evacuation.

We analyzed 210 patients and 199 were included. Most were noncommissioned members (63.3%) and belonged to the Army (75.4%) and the Gendarmerie (15.6%). Injury or illness was duty-related in 66.2% of patients. The main cause for evacuation was nonbattle injury (63.3%), followed by illness (27.1%). Battle stress and injury accounted for 9.5%. The main reasons for evacuation were surgical conditions (58.3%), particularly orthopedic (47.2%). Medical (22.1%), psychiatric (18.6%), and dental (1.0%) disorders followed. Most patients were categorized by the flight surgeon as P3 (98.5%), the lowest level of priority, and D4 (82.9%), the lowest level of dependency. The escort used during evacuation was identical to that recommended by the requester in 83.5% of cases. The final destination was mainly a hospital (89.9%). The time lag between injury or onset of illness and the request for evacuation was significantly longer when local health resources were insufficient.

The particularity of FG is a local health care system that provided initial care before the evacuation. To reduce the number of Strat-AEs in FG, the risk of nonbattle injury must be lessened and improvements must be made to the local health care system and to the partnership between civilian and military health services.
