DRONE-WOUND Study: Severe Infection After Drone-Related Combat Trauma

Overview

Drone-related combat injuries have become one of the most devastating mechanisms of injury in modern warfare. These injuries often cause extensive tissue devitalization, contamination, open fractures, vascular injuries, and complex soft tissue damage, which may substantially increase the risk of severe wound infection, multidrug-resistant bacterial infection, repeated surgical procedures, limb loss, and sepsis. However, the relationship between the extent of tissue devitalization and the development of severe infection has not been systematically investigated. The DRONE-WOUND Study is a prospective observational cohort study designed to evaluate the association between tissue devitalization and severe wound infection in patients with drone-related combat trauma. The study will collect detailed clinical, surgical, microbiological, and radiological data from injured patients treated at participating trauma centers. Measures of tissue injury, contamination, surgical management, microbiological findings, and infection outcomes will be analyzed to identify factors associated with severe infection and poor clinical outcomes. The findings of this study are expected to improve understanding of the mechanisms leading to infection after drone-related injuries, support early identification of high-risk patients, and inform future strategies for surgical management, antimicrobial therapy, and infection prevention in combat trauma. Ultimately, the study aims to improve limb salvage, reduce infectious complications, and enhance outcomes for patients with severe drone-related injuries.

The widespread use of unmanned aerial vehicles (UAVs), including first-person view (FPV) drones and explosive drone-delivered munitions, has fundamentally changed the pattern of combat injuries. Compared with conventional gunshot wounds and traditional blast injuries, drone-related trauma frequently results in extensive soft tissue destruction, deep tissue devitalization, severe contamination, open fractures, vascular injury, and complex multisystem extremity trauma. These injuries often require repeated surgical debridement, prolonged antimicrobial therapy, reconstructive procedures, and extended rehabilitation. Severe wound infection remains one of the leading causes of morbidity following combat-related extremity trauma. However, the mechanisms linking the extent of tissue devitalization with subsequent infectious complications have not been adequately characterized. Early identification of patients at high risk for severe infection could improve surgical decision-making, optimize antimicrobial stewardship, and reduce the incidence of limb loss, sepsis, and other major complications. The DRONE-WOUND Study is designed to characterize the relationship between tissue devitalization and severe infection following drone-related combat trauma. The study will prospectively collect standardized clinical, operative, microbiological, and imaging data from patients with combat-related injuries treated at participating trauma centers. Particular attention will be given to the extent of tissue devitalization, contamination, vascular injury, fracture characteristics, timing and number of surgical procedures, microbiological findings, antimicrobial therapy, and infection-related outcomes. The study will evaluate clinical and injury-related factors associated with severe wound infection and describe the microbiological spectrum of infections, including multidrug-resistant organisms. Secondary analyses will investigate the association between tissue injury severity and the need for repeated debridement, reconstructive surgery, amputation, prolonged hospitalization, intensive care admission, and mortality. The results are expected to improve understanding of infection pathogenesis following drone-related combat injuries and provide evidence to support risk stratification, surgical management, infection prevention, and antimicrobial treatment strategies in modern combat trauma. The findings may also contribute to the development of future clinical prediction models and standardized management protocols for patients sustaining drone-related injuries.
