In response to mass casualty events, The Hartford Consensus brought together subject matter experts across multiple disciplines in health care and public safety to create guidelines and publications intended to improve survivability in active shooter events. Among the recommendations was the earlier recognition and treatment application of life-threatening hemorrhage control. These recommendations culminated in efforts to create the Stop the Bleed Campaign, which aims to empower the layperson to render aid in a life-threatening bleeding emergency. As of February 2020, the program has held over 86,000 courses, trained over 1.4 million attendees, and over 77,000 instructors since its inception. In addition to spreading within the United States, American College of Surgeons (ACS) Stop the Bleed (StB) classes have been held in 118 different countries. This systematic narrative review aims to answer the following research question: What does the ACS StB Initiative do well, and where can it improve? ⋯ StB is an effective tool in building confidence in laypersons, which is its biggest strength. A review of the literature shows several areas where the curriculum and materials could be better developed. Research can also be further refined to better quantify the program's impact.

Objectively determining soldiers' fatigue levels could help prevent injuries or accidents resulting from inattention or decreased alertness. Eye-tracking technologies, such as optical eye tracking (OET) and electrooculography (EOG), are often used to monitor fatigue. Eyeblinks-especially blink frequency and blink duration-are known as easily observable and valid biomarkers of fatigue. Currently, various eye trackers (i.e., eye-tracking glasses) are available on the market using either OET or EOG technologies. These wearable eye trackers offer several advantages, including unobtrusive functionality, practicality, and low costs. However, several challenges and limitations must be considered when implementing these technologies in the field to monitor fatigue levels. This review investigates the feasibility of eye tracking in the field focusing on the practical applications in military operational environments. ⋯ Monitoring physiological and psychological readiness of soldiers, as well as other civil professionals that face higher risks when their attention is impaired or reduced, is necessary. However, improvements to eye-tracking devices' hardware, calibration method, sampling rate, and algorithm are needed in order to accurately monitor fatigue levels in the field.

Musculoskeletal injuries (MSKIs) are a significant health problem in the military. Accordingly, identifying risk factors associated with MSKI to develop targeted strategies that attenuate injury risk remains a top priority within the military. Insufficient sleep has garnered increased attention as a potential risk factor for MSKI in both civilians and military personnel. Yet, there are no systematic evaluations of the potential association between sleep and MSKI in the military. The purpose of this review is to examine the relationship between sleep and injury in military personnel. ⋯ This is the first systematic review to evaluate the published literature on the association between sleep and MSKI risk in military populations. Although there is currently limited research on this topic, findings suggest that sleep is associated with MSKI and should be considered when designing strategies aimed at reducing MSKI risk in military personnel.

The U.S. military has a 50-year history of managing resettlement or refugee camps on bases. In July and August 2021, more than 124,000 persons were evacuated from Afghanistan, with 55,000 Afghans temporarily housed at U.S. military bases around the world during Operation Allies Welcome (OAW) at its peak. ⋯ Partners and providers involved in any refugee setting should become familiar with updated guidelines, standards, and best practices and apply them to any operation to ensure a rights-based approach to protection, care, and the health and well-being of refugees.
