For behind armor blunt trauma (BABT), recent prominent BABT standards for chest plate define a maximum deformation distance of 44 mm in clay. It was developed for soft body armor applications with limited animal, gelatin, and clay tests. The legacy criterion does not account for differing regional thoracoabdominal tolerances to behind armor-induced injury. This study examines the rationale and approaches used in the legacy BABT clay criterion and presents a novel paradigm to develop thoracoabdominal regional injury risk curves. ⋯ While the original authors stressed limitations and the importance of additional tests for refining the 44 mm recommendation, they were not pursued. As live swine tests are effective in developing injury criteria and the responses of different areas of the thoracoabdominal regions are different because of anatomy, structure, and function, a new set of swine and human cadaver tests are necessary to develop scaling relationships. Live swine tests are needed to develop incapacitation/lethal injury risk functions; using scaling relationships, human injury criteria can be developed.

Preventable patient harm has persisted in health care despite recent advances to reduce errors. There is increasing recognition that non-technical skills, including communication and relationships, greatly impact interprofessional team performance and health care quality. Team familiarity and size are critical structural components that potentially influence information flow, communication, and efficiency. ⋯ For military surgical teams, greater familiarity and smaller team sizes were associated with small improvements in communication effectiveness. Military leaders can likely enhance team communication by engaging in a thoughtful and concerted program to foster cohesion by building familiarity and optimizing team size to meet task and cognitive demands. We suggest leaders develop bundled approaches to improve communication by integrating team familiarity and team size optimization into current evidence-based initiatives to enhance performance.

Orbital compartment syndrome (OCS) is an ocular emergency requiring prompt decompression with a lateral canthotomy and cantholysis (LCC) within 2 hours. This study evaluates the feasibility and effectiveness of a standardized LCC curriculum to train medical students to identify and treat OCS. ⋯ This study successfully developed a standardized LCC curriculum utilizing the principles of hands-on mastery learning to train novice learners to perform an LCC efficiently and effectively.

Protocol for the Implementation of Psychologically Informed Physical Therapy to Prevent Chronification in Service Members With Musculoskeletal Disorders.
Musculoskeletal disorders (MSDs) are a primary cause of separation and long-term disability in active duty service members (ADSMs). Psychologically informed physical therapy (PiPT) is designed to identify and address modifiable psychological risk factors early in an MSD episode and has been proven effective in preventing chronicity in civilian populations. We developed a course to train military physical therapy (PT) personnel in PiPT for treating ADSM with MSD. This study tests the feasibility and effectiveness of our training. ⋯ Data collection is ongoing. Findings will identify the factors associated with PiPT outcomes in ADSM, inform the implementation of PiPT across health care settings, and allow us to document the prevalence of risk factors for chronicity in ADSM. Findings can help to prevent chronification from MSD, thereby reducing lost man-hours and enhancing military readiness, contribute to the development of a highly skilled workforce for the provision of health services to ADSM, and enhance the efficiency of health care delivery through optimal allocation of PT resources, resulting in significant cost savings for the military.
