Sports Injuries among Deployed US Service Members between October 2001 and December 2018.

BACKGROUND: Sports injuries are an important non-battle cause of attrition and morbidity among deployed US service members (SMs). Injuries secondary to sport may cause physical disability and prolonged periods of limited duty days. Our objective was to provide a descriptive analysis of sports injuries sustained by US SMs which may assist in the preventive strategies and thereby decrease their burden on the deployed force. METHODS: Using the Department of Defense Trauma Registry's (DoDTR) data between October 2001 and December 2018, a retrospective cross-sectional analysis was conducted. We reported summary statistics of injury characteristics and care provided, stratified by geographic location. RESULTS: We found 1,578 causalities with sport injuries (4.9% of DoDTR); 1,081 (68.5%) in Iraq and Syria and 497 (31.5%) in Afghanistan. Most casualties had mild injuries (injury severity score: 1-9; n=1,514; 95.9%) and most sustained injuries in the lower extremities (n=741; 47%) followed by upper extremities (n=430; 27.2%). Most injuries were caused by a striking force (n=827; 52.4%) followed by overexertion (n=444; 28.2%), and 512 casualties (32.4%) had a fall incident. About 833 casualties (52.8%) received at least one surgery, and 931 casualties (59%) were hospitalized for two days or more. One casualty died of wound (0.1%). CONCLUSIONS: Sports injuries continue to be an important source of morbidity and attrition and require disproportional medical attention, relative to their mild severity, representing a significant burden to the deployed health care system and impact combat readiness. Further research addressing the prevention of sports injury among deployed US SMs is needed.

Prehospital Battlefield Casualty Intervention Decision Cognitive Study.

INTRODUCTION: Airway compromise is the third most common cause of preventable battlefield death. Surgical cricothyroidotomy (SC) is recommended by Tactical Combat Casualty Care (TCCC) guidelines when basic airway maneuvers fail. This is a descriptive analysis of the decision-making process of prehospital emergency providers to perform certain airway interventions. METHODS: We conducted a scenario-based survey using two sequential video clips of an explosive injury event. The answers were used to conduct descriptive analyses and multivariable logistic regression models to estimate the association between the choice of intervention and training factors. RESULTS: There were 254 respondents in the survey, 176 (69%) of them were civilians and 78 (31%) were military personnel. Military providers were more likely to complete TCCC certification (odds ratio [OR]: 13.1; confidence interval [CI]: 6.4-26.6; P-value < 0.001). The SC was the most frequently chosen intervention after each clip (29.92% and 22.10%, respectively). TCCC-certified providers were more likely to choose SC after viewing the two clips (OR: 1.9; CI: 1.2-3.2; P-value: 0.009), even after controlling for relevant factors (OR: 2.3; CI: 1.1-4.8; P-value: 0.033). CONCLUSIONS: Military providers had a greater propensity to be certified in TCCC, which was found to increase their likelihood to choose the SC in early prehospital emergency airway management.

Description of trauma among French service members in the Department of Defense Trauma Registry: understanding the nature of trauma and the care provided.

BACKGROUND: Since 2001, the French Armed Forces have sustained many casualties during the Global War on Terror; however, even today, there is no French Military trauma registry. Some French service members (SMs) were treated in US Military Medical Treatment Facilities (MTFs) and were recorded in the US Department of Defense Trauma Registry (DoDTR). Our objective was to conduct a descriptive analysis of the injuries sustained by French SMs reported in the DoDTR and subsequent care provided to them to assist in understanding the importance of building a French Military trauma registry. METHODS: Using DoDTR data collected from 2001 to 2017, a retrospective descriptive analysis was conducted. We identified 59 French SMs treated in US MTFs. The characteristics of the SMs' demographics, injuries, care provided to them, and discharge outcomes were summarized. RESULTS: Among the 59 French SMs identified, 46 (78%) sustained battle injuries (BIs) and 13 (22%) sustained nonbattle injuries (NBIs). There were 47 (80%) SMs injured in Afghanistan (Opération Pamir), while 12 (20%) were injured in Opération Chammal in Iraq and Syria. Explosives accounted for 52.5% of injuries, while 25.4% were due to gunshot wounds; all were BIs. The majority of reported injuries were penetrating (59.3%), most of which were BIs (71.7%). The mean Injury Severity Score for BIs was 12 (SD = 8.9) compared to 6 (SD = 1.7) for NBIs. Around half of SMs (n = 30; 51%) were injured in Afghanistan between the years 2008-2010. Among a total of 246 injuries sustained by 59 patients, extremities were the body part most prone to BIs followed by the head and face. Four SMs died after admission (6.8%). CONCLUSIONS: The DoDTR provides extensive data on trauma injuries that can be used to inform injury prevention and clinical care. The majority of injuries sustained by French SMs were BIs, caused by explosives, and predominantly occurring to the extremities; these findings are similar to those of other studies conducted in combat zones. There is a need to establish a French Military trauma registry to improve the combat casualty care provided to French SMs, and its creation may benefit from the DoDTR model.

Nonfatal motor vehicle related injuries among deployed US Service members: Characteristics, trends, and risks for limb amputations.

BACKGROUND: Motor vehicle-related (MVR) incidents are important causes of morbidity among deployed US service members (SMs). Nonbattle MVR injuries are usually similar to civilian MVR injuries, while battle MVR injuries are often unique due to the blast effects from precipitating explosive mechanisms. Our primary objective was to describe the characteristics and trends of nonfatal MVR injuries sustained by deployed US SMs. A second objective was to assess the association between mechanism of injury (i.e., explosive vs. nonexplosive) and limb amputation. METHODS: We conducted a retrospective cross-sectional analysis using data from the Department of Defense Trauma Registry collected from October 2001 to December 2018. Descriptive statistics were reported stratified by mechanism of injury (explosive vs. nonexplosive). The association between mechanism of injury and limb amputation was assessed using logistic regression models. RESULTS: There were 3,119 US casualties who sustained nonfatal MVR injuries, 2,380 (76.3%) SMs sustained nonexplosive MVR injuries while 739 (23.7%) sustained explosive MVR injuries. Of all MVR casualties, 2,085 (66.9%) were in Iraq or Syria and 1034 (33.1%) in Afghanistan. The annual prevalence of nonfatal MVR battle casualties was highest in Iraq and Syria from 2003 to 2009 and Afghanistan from 2009 to 2014, ranging overall 15 to 50 MVR casualties per 1,000 wounded in action. There were 92 limb amputations associated with MVR incidents. Compared with nonexplosive MVR mechanisms, explosive MVR mechanisms had higher association with limb amputation (adjusted odds ratio, 2.6; confidence interval, 1.7-3.9), even after adjusting for injury year and Injury Severity Score (AOR, 2.1; confidence interval: 1.4-3.4). CONCLUSION: Motor vehicle-related incidents are an important cause of injury in US military operations. Compared with nonexplosive MVR incidents, explosive MVR incidents result in more severe injuries, and have a higher associated risk of limb amputation. Continued efforts to improve injury prevention through protective equipment and medical training specific to MVR injuries are needed.
