Disease Control Priorities, 3rd Edition (DCP3) is an evidence-based, published resource that outlines essential procedures recommended for developing health care systems. These systems must consider various populations and the incidence of certain surgical conditions that require treatment. In relation to pediatric patients, the prevalence of certain surgical conditions encountered remains unclear in several low- and middle-income countries. Over the past 15 years, the USNS Mercy, one of the U.S. Navy's large hospital ships, has led the Pacific Partnership missions, which provide large-scale humanitarian aid throughout Southeast Asia. The data collected during these missions provide an opportunity to analyze the scope of pediatric operations performed in resource-limited countries. This analysis may assist in future planning for specific needs during military humanitarian missions. ⋯ This study represents the largest known analysis of military humanitarian assistance. Pediatric operations represented over one-third of the surgical volume during Pacific Partnership missions from 2006 to 2018. The majority of cases were DCP3-aligned and associated with a low complication rate. Future humanitarian aid missions and host nations should allocate appropriate medical and educational resources to treat DCP3 pediatric surgical diseases in low- and middle-income countries to support long-term capacity building while maintaining optimal surgical outcomes.

Psychiatric complaints account for a sizable and increasing portion of emergency department (ED) visits. Compared with other medical patients, these patients often require substantial resources because of limited specialized resources and prolonged boarding times, which can be detrimental to the safety and satisfaction of other patients. This can prompt early and indiscriminate laboratory testing to expedite early requests for admission consideration. Numerous emergency medicine literature and clinical policies already recommend against indiscriminate screening labs for these patients, yet many psychiatric services require these tests. This study further evidences the limited clinical utility and high associated costs of mandatory protocol screening labs for psychiatric patients evaluated in military EDs. ⋯ The cumulative reimbursement costs of broad testing in the studied population were estimated at $36,325.17 and rarely altered patient disposition. Further testing does not increase the incidence of disposition altering diagnoses and is associated with increased costs. When individual state laws and the clinical assessment by the responsible emergency physician are considered, future standardized ED lab screening evaluations of psychiatric patients in military EDs may be concentrated to breathalyzer alcohol level, urine drug screen, serum salicylates, serum acetaminophen, and urine human chorionic gonadotropin.

Hypothermic ex-situ machine perfusion (MP) has been shown to be a promising alternative to static cold storage (SCS) for preservation of solid organs for transplantation and vascularized composite allotransplantation. Perfusion with blood-based perfusion solutions in austere environments is problematic due to their need for appropriate storage and short shelf life, making it impractical for military and emergency use. Acellular perfusion has been shown to be effective, but the ideal perfusate solution for MP of amputated limbs is yet to be determined. The purpose of this study is to evaluate the efficacy of alternative perfusate solutions, such as dextran-enriched Phoxilium, Steen, and Phoxilium in ex-vivo hypothermic MP of amputated limbs in a porcine model. ⋯ With the exception of significantly higher levels of creatine kinase and lactate dehydrogenase, MP with dextran-enriched Phoxilium provides similar results as that of the commercially available perfusates such as Steen, without the need for cold storage, and at circa 5% of the cost of the Steen solution. Further large-scale replantation studies are necessary to evaluate the efficacy of dextran-enriched Phoxilium as an alternate perfusate solution.

The propensity for air mobility missions to exhaust aircrews is strongly dependent on operational tempo. Most flying is performed during periods of low to moderate operational tempo, but a major flight safety risk can emerge when operational tempo becomes very high. This risk can be managed by software tools that contain fatigue and sleep behavior modeling, but optimization/validation of the model using the specific target population is required to ensure that the modeled predictions are accurate. The goal of the study was to validate the sleep behavior model settings for a fatigue modeling tool that is used within the RCAF, the Fatigue Avoidance Scheduling Tool, taking into account the organizational requirements for pre- and postflight routines, especially within the Air Mobility force. ⋯ Current Fatigue Risk Management Systems require accurate fatigue and sleep behavior modeling, which can only be achieved by studying specific target populations to determine their culture of work/rest routines, and optimizing sleep behavior model settings accordingly.

The U.S. Army requires community health coalitions to develop targeted action plans in order to more effectively address top public health priorities. Reviews of community action plans indicate that they are often poorly developed and not fully implemented. To date, the U.S. Army has not implemented a standardized tool or process to evaluate action plans and provide recommendations for improvement to local installations. The Plan Quality Index (PQI) is an evidence-based, standardized tool that has been used successfully by technical experts to review and improve community action plans related to the prevention of obesity, injury and violence, and cancer. ⋯ The PQI demonstrated a high level of usability by technical experts for providing feedback and recommendations regarding community health action plans for injury prevention in the U.S. Army. As a result, the PQI may be beneficial as a standard tool for community health improvement planning and consultation throughout the Army Public Health Center.
