Recent malicious use of chemical warfare agents (CWAs) is a reminder of their severity and ongoing threat. One of the main categories of CWAs is the organophosphate (OP) nerve agents. Presently, there is an urgent need to identify and evaluate OP nerve agent biomarkers that can facilitate identification of exposed individuals post-CWA incident. While exposures to OP nerve agents may be scenario-specific, the public is commonly exposed to OP compounds through the ubiquitous use of OP pesticides, which are chemically related to nerve agents. Therefore, a systematic literature review and methodological quality assessment were conducted for OP pesticide biomarker studies to serve as a baseline to assess if these approaches may be adapted to OP nerve agent exposures. ⋯ Cholinesterase activity may have utility for identifying individuals with exposures surpassing a given threshold of OP nerve agent, but further investigation of how acetylcholinesterase and butyrylcholinesterase levels correlate with observed patient symptoms may be required to ensure accuracy of results. As CWAs and nerve agents are more readily used, more standardized reporting of biomarker measurements are needed to develop new approaches for OP nerve agent biomarkers.

Because of the rigorous mental and physical health requirements for Naval Aviation, all applicants and designated personnel must meet physical standards, including initial and periodic screening for anemia. Most standards, including for accession to the U.S. Navy, use hemoglobin as the standard marker to screen for anemia. Moreover, previous literature generally supports the assertion that hemoglobin is more reliable and accurate than hematocrit. However, the U.S. Navy Aeromedical Reference and Waiver Guide uses a hematocrit standard for anemia screening. The purpose of this study was to determine whether hemoglobin or hematocrit correlates better with clinical anemia and evaluate which index is a more accurate indicator for anemia screening in Naval Aviation personnel. ⋯ This study found that hemoglobin correlates better with the diagnosis of anemia than hematocrit. When three samples are analyzed, hemoglobin is equally sensitive and more specific than hematocrit. Based on these results and the U.S. Navy accession standards using hemoglobin as the standard index for anemia, the U.S. Navy Aeromedical Reference and Waiver Guide should consider using hemoglobin instead of hematocrit to screen for anemia. Future research should focus on prospective research to determine whether hemoglobin or hematocrit is a better indicator of anemia in screening military personnel.

Family members are important supports for veterans with Posttrauamtic Stress Disroder (PTSD), but they often struggle with their own distress and challenges. The Veterans Affairs-Community Reinforcement and Family Training (VA-CRAFT) website was designed to teach family members of veterans with PTSD effective ways to interact with their veterans to encourage initiation of mental health services as well as to care for themselves and improve their relationships. This article presents a pilot investigation of VA-CRAFT. ⋯ Results from this pilot trial suggest that VA-CRAFT holds initial promise in reducing caregiver burden and as such it could be a useful resource for family members of veterans with PTSD. However, VA-CRAFT does not enhance veteran treatment initiation. It may benefit from enhancements to increase effectiveness and caregiver engagement.

Medical error is the third leading cause of death in the United States, contributing to suboptimal care, serious patient injury, and mortality among beneficiaries in the Military Health System. Recent media reports have scrutinized the safety and quality of military healthcare, including surgical complications, infection rates, clinician competence, and a reluctance of leaders to investigate operational processes. Military leaders have aggressively committed to a continuous cycle of process improvement and a culture of safety with the goal to transform the Military Health System into a high-reliability organization. The cornerstone of patient safety is effective clinician communication. Military surgical teams are particularly susceptible to communication error because of potential barriers created by military rank, clinical specialty, and military culture. With an operations tempo requiring the military to continually deploy small, agile surgical teams, effective interpersonal communication among these team members is vital to providing life-saving care on the battlefield. ⋯ The findings have important implications for safety and quality. Stronger connections in the interaction frequency, close working relationship, socialization, and advice networks were associated with smaller differences in communication effectiveness. The ability of team members to communicate clinical information effectively is essential to building a culture of safety and is vital to progress towards high-reliability. The military faces distinct communication challenges because of policies to rotate personnel, the presence of a clear rank structure, and antifraternization regulations. Despite these challenges, overall communication effectiveness in military teams will likely improve by maintaining team consistency, fostering team cohesion, and allowing for frequent interaction both inside and outside of the work environment.

The U.S. Department of Veterans Affairs (VA), the single largest health care system in the United States, provides comprehensive medical and behavioral health services to more than 9 million Veterans. The size and scope of the VA's system of care allow health care providers, policymakers, and community stakeholders to conduct detailed analyses of health care utilization among Veterans; however, these analyses do not include health care encounters that occur outside VA. Although many Veterans obtain care in non-VA settings, understanding health care utilization among vulnerable populations of Veterans, including those who are homeless or at risk of becoming homeless, is needed to identify potential opportunities to enhance access and reduce fragmentation of care. ⋯ Veterans eligible for VA servicers who are homeless, or at risk of becoming homeless, frequently sought care in the community for a variety of chronic health conditions. Health information exchanges and partner-based registries may represent an important tool for identifying vulnerable Veteran populations while reducing duplication of care.
