The journal of trauma and acute care surgery · 2026-06-04 · Observational study
Abstract
BACKGROUND: The National Gendarmerie Intervention Group (GIGN) is the French National Gendarmerie's tactical unit, operating in high-risk environments involving armed suspects, hostage situations, or counterterrorism. Since 1984, the GIGN has relied on an original medical support model integrating a military physician-nurse team within its tactical elements. The study aimed to describe this support within the specific context of a physician-led prehospital emergency medical system. METHODS: We conducted a retrospective, descriptive, observational study of all GIGN operations identified from a prospective registry and performed in the French homeland between July 12, 2018, and October 12, 2022. The primary outcome was the occurrence of at least one casualty, defined as receiving a medical evaluation during an operation. Operational characteristics, medical organization, casualty severity, and access times to medical resources were analyzed. Univariate analyses were performed to identify factors associated with casualty occurrence. RESULTS: Among 242 analyzed operations, at least one casualty occurred in 21% of missions (n=50), with a total of 90 casualties managed. Law enforcement missions were associated with a significantly higher risk of casualties compared with judicial missions (39% vs. 15%; OR: 3.64, 95% CI: 1.82-7.23). Armed or suspected armed adversaries were present in 79% of operations, with explosives linked to the highest risk. Median theoretical access times were 15 minutes (IQR, 9-22) to a physician-staffed prehospital emergency unit and 40 minutes (IQR, 22-63) to a trauma center, with 22% of operations located more than 1 hour away. Prehospital transfusion was potentially available in 66% of operations, mostly delivered within 60 minutes. CONCLUSIONS: GIGN operations are conducted in environments with substantial exposure to severe trauma. Its embedded support model enables early advanced medical care targeting preventable causes of death and plays a central role in operational planning, coordination with civilian emergency services, and casualty management.
