ABSTRACT
The most serious types of heat illnesses, heat exhaustion and heat stroke, are occupational hazards associated with many of the military's training and operational environments. These illnesses can typically be prevented by appropriate situational awareness, risk management strategies, along with effective countermeasures. In 2023, the crude incidence of heat stroke and heat exhaustion were 31.7 and 172.7 cases per 100,000 person-years, respectively. The rates of incident heat stroke declined during the 2019 to 2023 surveillance period, but rates of incident heat exhaustion increased over the same period. In 2023, higher rates of heat stroke were observed among male service members compared to their female counterparts, and female service members experienced higher rates of heat exhaustion compared to male personnel. Heat illness rates were also higher among those younger than age 20, Marine Corps and Army service members, non-Hispanic Black service members, and recruits. Leaders, training cadres, and supporting medical and safety personnel must inform their subordinate and supported service members of heat illness risks, preventive measures, early signs and symptoms of illness, and appropriate interventions.

Abstract: A total of 254 febrile acute respiratory disease (ARD) cases were identified among Army basic trainees in 2022. No Army basic training installations met the definition for an ARD or Group A Beta-Hemolytic Streptococcus outbreak in 2022. The inclusion of afebrile ARD data in the surveillance program identified an additional 1,696 cases in which a trainee met the criteria for a case of ARD, except for an oral temperature of 100.5°F or higher. While including afebrile cases in the ARD rate calculation did result in an overall increase in weekly ARD rates, no basic training installations met the MEDCOM definition for an ARD outbreak. The continued surveillance and implementation of interventions such as chemoprophylaxis, vaccination, and non-pharmacologic interventions (e.g. hand-washing, head-to-toe sleeping bunk arrangement, etc.) helped identify and potentially prevent ARD outbreaks. What are the new findings?: In 2022, no ARD outbreaks were identified at any U.S. Army basic training installations, according to the U.S. Army's Medical Com-mand (MEDCOM) definition. This marks the third consecutive year without an ARD outbreak at these installations. Vaccination, chemoprophylaxis, and active disease surveillance are cornerstones of the Army's program to protect the health and readiness of basic trainees, utilizing support from the Defense Health Agency's Defense Centers for Public Health. What is the impact on readiness and force health protection?: U.S. Army basic training provides an ideal environment for the development of respiratory disease outbreaks because of sustained high stress combined with close trainee living and training quarters. Disease outbreaks degrade force readiness by increasing training time or potentially reducing numbers of trainees who graduate. The data from 2020 through 2022 demonstrate that no ARD outbreaks occurred in this population.

INTRODUCTION: This study estimated the direct medical and indirect costs associated with coronavirus disease 2019 (COVID-19) diagnoses among U.S. active duty (AD) Army service members (SMs). These cost estimates provide the U.S. Military with a better understanding of the financial burden of COVID-19 and provide a foundation for cost-effectiveness estimates. MATERIALS AND METHODS: The study was approved as Public Health Practice (#17-605) by the U.S. Army Public Health Center, Public Health Review Board. U.S. AD Army SMs with COVID-19 were identified using an Army COVID-19 testing and surveillance database. Encounters for these SMs were captured from medical record where International Classification of Disease Tenth Revision, Clinical Modification code U07.1 was in the first or second diagnostic position. Analyses were conducted on SMs with COVID-19 who either had no healthcare encounters in the Military Health System (MHS); at least one MHS COVID-19 inpatient hospitalization; or at least one MHS outpatient COVID-19 encounter. Coronavirus disease 2019 (COVID-19) costs captured from the encounters were used to develop direct medical cost estimates. Literature on COVID-19 recovery post-hospitalization, along with the number of COVID-19 hospitalizations and outpatient visits from encounters were used to describe the intensity of COVID-19 care. Estimates of the indirect cost of lost duty were based on SMs salary information, along with recovery time, bed days, or outpatient visit time. The indirect cost of limited duty was estimated using the time associated with the Department of Defense (DoD) COVID-19 pandemic mitigation strategies in place when these SMs were identified as positive for COVID-19. RESULTS: Coronavirus disease 2019 (COVID-19) cost estimates were developed for the Army using data from 19,086 SMs identified as positive for COVID-19 between June 1, 2020, and December 31, 2020. Direct medical costs, or the amount paid by the DoD to facilities for COVID-19 care, averaged $606 per SM with an encounter. Indirect costs for lost duty or the cost for recovery and the time taken to seek care for COVID-19 averaged $319 per SM, while indirect costs for limited duty or isolation associated with COVID-19 averaged $4,111 per SM or $411 per day. Service members (SMs) with an inpatient hospitalization averaged 4.8 bed days (range 1-43) and 266 recovery hours while SMs who sought outpatient care for COVID-19 averaged two outpatient visits (range 1-60 visits). CONCLUSIONS: The direct medical costs of a COVID-19 encounter in the MHS ($606) are a small portion of the costs for a SM with COVID-19. Indirect costs of lost and limited duty associated with COVID-19 averaged seven times higher ($4,331) and accounted for the vast majority of costs. Recognition of these costs is important especially given that soldiers in the hospital or in quarters being quarantined are complete losses of manpower to the Army. While the COVID-19 pandemic is ongoing and prevention, treatment, and mitigation efforts continue to evolve, having reliable estimates of direct medical and indirect costs from this study allows the U.S. Army and MHS to better account for the cost of this pandemic for its population.
ABSTRACT
The EpiData Center (EDC) has provided routine blood lead level (BLL) surveillance for Department of Defense (DoD) pediatric beneficiaries since 2011. Data for this study were collected and compiled from raw laboratory test records obtained from the Composite Health Care System Health Level 7 (HL7)-formatted chemistry data, allowing an overview of the number of tests performed and the number of elevated results. Between 2010 and 2017, there were 177,061 tests performed among 162,238 pediatric beneficiaries tested. Using only the highest test result per year for each individual, 169,917 tests were retained for analysis, of which 1,334 (0.79%) test results were considered elevated. The percentage of children with elevated BLLs generally decreased over the time period for children of every service affiliation. All tests throughout this time frame were evaluated using current standards and the protocol followed by the Centers for Disease Control and Prevention and the Department of the Navy (DON). The adoption of a standardized BLL surveillance methodology across the DoD supports a cohesive approach to an evolving public health surveillance topic.
