Emerging biological threats represent a serious challenge for force health protection (FHP). Against a novel biological threat, medical countermeasures are the first line of defense. However, as exposed by global pandemic conditions, there are significant complications when administering medical countermeasures against novel threats. One such limitation involved the lack of any guiding structure to discuss and deliberate upon the relative value of employing different countermeasures either alone or in tandem. For example, both personal protective equipment and prophylactic medication can provide some protection, but how are individual protections weighed against operational capabilities and FHP initiatives? The goal of this review is to provide a hierarchical organizing structure to the different medical countermeasures available in response to emerging biological threats. ⋯ Identifying medical countermeasures is important to optimizing FHP. Different countermeasures have different advantages, and the hierarchy distinguishes between inferior and superior countermeasures through the push-pull style mechanism of resource-durability assessment. Future deployment and development should focus on superior countermeasures to maximize medical protections and operational readiness while understanding the relative value and complications inherent with different countermeasures.

Multitasking typically requires an individual to simultaneously process cognitive information while performing a motor task. Cognitive motor interference (CMi) is encountered when cognitive challenges negatively impact motor task performance. Military personnel encounter cognitively taxing situations, especially during combat or other tactical performance scenarios, which may lead to injury or motor performance deficits (i.e., shooting inaccuracy, delayed stimulus-response time, and slowed movement speed). The purpose of the current study was to develop four cognitive motor shooting paradigms to determine the effects of cognitive load on shooting performance in healthy Reserve Officers' Training Corps (ROTC) cadets. ⋯ The addition of a cognitive load increased both task initiation and task completion times during cognitive motor simulated shooting. Adding cognitive loads to tactical performance tasks can result in CMi and negatively impact tactical performance. Thus, consideration for additional cognitive challenges into training may be warranted to reduce the potential CMi effect on tactical performance.

Clostridioides difficile infection (CDI) has become a rising public health threat. Our study aims to characterize the epidemiology and measure the attributable cost, length of stay, and in-hospital mortality of healthcare facility-onset Clostridioides difficile infection (HO-CDI) among patients in the U.S. Military Health System (MHS). ⋯ Healthcare facility-onset Clostridioides difficile infection is rising in patients within the MHS and is associated with increased length of stay, hospital costs, and in-hospital mortality. We identified a significantly increased burden of hospitalization among patients admitted with HO-CDI, highlighting the importance of infection control and antimicrobial stewardship initiatives aimed at decreasing the spread of this pathogen.

Airway obstruction is the second leading cause of potentially survivable death on the battlefield. The Committee on Tactical Combat Casualty Care lists airway optimization among the top 5 battlefield research and development priorities; however, studies show that combat medics lack access to the recommended supraglottic airway (SGA) devices. SGA devices are an alternative airway management technique to endotracheal tube intubation. Reports have shown SGA devices are easier to use and take fewer attempts to provide patent airflow to the patient when compared to endotracheal tube intubation. Military settings require a higher degree of skill to perform airway management on patients due to the environment, limited availability of equipment, and potential chaos of the battlefield. Finding the optimal SGA device for the military setting is an unmet need. The International Organization for Standardization describes basic functional requirements for SGA devices, as well as patient configurations and size limitations. Beyond that, no SGA device manufacturer states that their devices are intended for military settings. ⋯ There are a variety of devices that require further testing to determine whether they should be included in sets, kits, and outfits.

Virtual health and secure messaging gained newfound relevance in medicine during the coronavirus disease (COVID)-19 pandemic. For a military trainee health care clinic located on Joint Base San Antonio, the McWethy Troop Medical Clinic (TMC), implementation of virtual health and secure messaging services meant decreased risk of COVID-19 exposure for trainees and clinical staff. ⋯ In defining the challenges, successes, and future implications for virtual health and secure messaging at the McWethy TMC, key lessons emerge for other military trainee clinics. The key concepts explored in this article are virtual health and secure messaging.
