Introduction: Military studies have investigated acute injuries associated with parachute jumps, but the literature does not address paratroopers' cumulative microtraumatic (CMT) injury risk, nor does it compare injury risks between paratroopers and the rest of the military population. This study determined whether US active duty Army paratroopers experienced greater injury risks than their non-paratrooper soldier counterparts and whether their injuries cost more to treat suggesting greater injury severity., Methods: This retrospective study evaluated electronic medical records (2016-2018) for 31 621 paratroopers and a randomly selected comparison group of 170 715 non-paratrooper soldiers. Analyses included univariate and multivariate regression to quantify odds of injuries associated with risk variables and additional descriptive statistics., Results: Paratroopers had a 57% increase in the odds of experiencing one or more injuries (OR=1.57, 95% CI: 1.52 to 1.62) after controlling for sex, race and age, with a greater proportion of acute injuries (OR=1.38, 95% CI: 1.34 to 1.42), relative to comparison group soldiers. Injury types proportionally higher among paratroopers included head trauma and shoulder injuries. Average injury cost among paratroopers was 13% lower than for non-paratroopers ($2470 vs $2830 per injury). Among both populations, acute injury costs were notably higher than for CMT injuries (paratroopers, $1710/$630; non-paratroopers, $1860/$880 per injury)., Conclusions: Paratroopers were more likely to incur injury, especially an acute injury, than non-paratroopers. However, paratroopers' average injury costs were less. This may be due to higher return-to-duty motivations, fitness levels, and/or facility-specific cost of care. Future studies should investigate causes of injuries found to be proportionally higher among paratroopers., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Introduction: Multiple studies report increasing cases of surgically treated pectoralis major (PM) muscle and tendon ruptures in military populations. Studies associate this with a growing popularity of weight-training and bench press exercises. Mild-to-moderate non-surgical PM traumas and overuse injuries have not been included in these studies despite evidence that these types of outpatient injuries account for the majority of the military's injury medical burden., Methods: To assess rates of all PM injuries (ruptures, tears, strains, overuse), regardless of form of treatment, a PM injury surveillance definition was derived from International Classification of Disease (ICD) diagnostic codes used in routine US Army injury surveillance. A detailed clinical examination of 2016 Active Duty Army medical records was used to identify ICD codes commonly associated with PM injuries. Cost data were calculated and the definition applied to medical data from 2016 through 2018to assess trends., Results: The estimated incidence of PM cases among soldiers was over 95% greater than if only considering severe surgical cases. Over 96% of army annual PM injury costs (direct medical and indirect from lost labour) were for outpatient services. PM injury incidence rates were not statistically different from 2016 to 2018., Conclusions: The PM injury surveillance definition provides a consistent means to monitor trends over time and evaluate the effectiveness of prevention efforts. PM injuries have a larger military impact than previously recognised and prioritised prevention strategies are needed to reduce them. Future interventions could focus on the bench press given its observed association with PM injuries., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objective: To estimate the financial burden to the U.S. Army of suicide by enlisted Soldiers during their first year of service., Methods: This analysis included new Army enlisted Soldiers who started initial entry training from October 2012 through September 2016 and subsequently died by suicide within their first year of service. Outpatient and inpatient direct medical, direct nonmedical, recruiting, and training costs to the Army were calculated., Results: During the 48-month observational study period, 29 Soldiers died by suicide within their respective first year of service. The described financial costs accrued by the Army as a result of these deaths were $152,271-with an average of $6,091 per healthcare utilizer. Recruiting and training costs were $1,115,860 for all suicide cases., Conclusion: Average direct cost per healthcare utilizer increased during a Soldier's first year of service. This may be associated with the transition through different phases of training and to the first operational duty station., Public Health Implications: Results obtained through this cost-of-illness analysis may serve as baseline metrics to inform future cost-effectiveness studies., (© 2021 The American Association of Suicidology.)

The estimated cost to the Army for lower extremity fractures in 2017 was approximately $116 million. Direct medical expenses totaled $24 million, and indirect medical costs totaled $92 million ($900 thousand lost duty; $91 million limited duty). Foot and toe fractures, along with lower leg and ankle fractures accounted for the majority of soldiers' initial visits for care (n=4,482; 91.6%), and more than $103 million (89.0%) of overall costs ($116 million). Costs varied by location of care. In outpatient settings, initial visits for foot and toe injuries accounted for the highest costs: $49 million overall. Direct medical costs totaled $1.2 million, and indirect medical costs (limited duty) were $48 million. Conversely, in inpatient settings, lower leg and ankle fractures accounted for slightly more than half of all costs (overall $9 million; $4.8 million in direct medical costs and $4.5 million in indirect medical costs). The finding that the majority of costs related to lower extremity fractures were due to estimated days of lost or limited duty and associated loss of productivity justifies the inclusion of indirect cost estimates as a part of overall injury cost calculations.

The novel coronavirus (severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) is exhibiting widespread community transmission throughout most of the world. Previous reports have evaluated the risk of serious illness in civilians diagnosed with COVID-19; however, similar reports have not been compiled for the Army active component (AC) population. COVID-19 has been a reportable condition for the Department of Defense since 5 February 2020, and, as of the morning of 6 April, a total of 873 cases were reported to the Disease Reporting System internet from Army installations. Of these cases, a total of 219 (25.1%) were identified as Army AC service members. The majority of these cases did not require hospitalization (n=207; 94.5%). The most common comorbidities present in nonhospitalized cases included other chronic illnesses (43.5%), neurologic disorders (24.6%), and obesity (21.7%). Overall, 12 cases (5.5%) required hospitalization. Hospitalized cases had a history of obesity (58.3%), neurologic disorder (50.0%), other chronic illnesses (41.7%), and hypertension (25.0%). No comorbidities were present among 27.1% (n=56) of nonhospitalized cases and 25.0% (n=3) of hospitalized cases.

Risk factors for heat illnesses (HIs) among new soldiers include exercise intensity, environmental conditions at the time of exercise, a high body mass index, and conducting initial entry training during hot and humid weather when recruits are not yet acclimated to physical exertion in heat. This study used data from the Defense Health Agency's-Weather-Related Injury Repository to calculate rates and to describe the incidence, timing, and geographic distribution of HIs among soldiers during U.S. Army basic combat training (BCT). From 2014 through 2018, HI events occurred in 1,210 trainees during BCT, resulting in an overall rate of 3.6 per 10,000 BCT person-weeks (p-wks) (95% CI: 3.4-3.8). HI rates (cases per 10,000 BCT p-wks) varied among the 4 Army BCT sites: Fort Benning, GA (6.8); Fort Jackson, SC (4.4); Fort Sill, OK (1.8); and Fort Leonard Wood, MO (1.7). Although the highest rates of HIs occurred at Fort Benning, recruits in all geographic areas were at risk. The highest rates of HI occurred during the peak training months of June through September, and over half of all HI cases affected soldiers during the first 3 weeks of BCT. Prevention of HI among BCT soldiers requires relevant training of both recruits and cadre as well as the implementation of effective preventive measures.
