Extensive efforts have been directed toward developing an effective vaccine to fight against the Coronavirus Disease 2019 (COVID-19); however, hesitancy to receive COVID-19 vaccinations has become detrimental to overcoming the COVID-19 pandemic. Although the U.S. Military instated a COVID-19 vaccine mandate, some members were still hesitant to receive the vaccine. To determine the efficacy of a program focused on vaccine hesitation, a program evaluation was conducted on a COVID-19 vaccine educational intervention (hereafter COVID-19 Educational Presentation) for trainees at Lackland Air Force Base, TX, in September 2021. Objectives of the educational session included (1) determining the participants' level of confidence that the COVID-19 vaccines are safe and effective, (2) understanding the concern for long-term side effects from COVID-19 vaccinations, and (3) identifying the driving forces behind hesitancy to receive a COVID-19 vaccination. ⋯ The COVID-19 Educational Presentation increased confidence and decreased hesitancy to receive the COVID-19 vaccine. Vaccine educational programs should continue in the military population to help combat misinformation and ensure that our military force is fully vaccinated and able to maintain mission readiness.

The majority of critical care air transport (CCAT) flights are regulated, meaning that a theater-validating flight surgeon has confirmed that the patient is medically cleared for flight and that evacuation is appropriate. If the conditions on the ground do not allow for this process, the flight is unregulated. Published data are limited regarding CCAT unregulated missions to include the period of troop drawdown at the end of the Afghanistan conflict. The objective of our study was to characterize the unregulated missions within Afghanistan during troop drawdown and compare them to regulated missions during the same timeframe. ⋯ During the troop drawdown in Afghanistan, the number of unregulated missions increased geometrically because the medical footprint was decreasing. During unregulated missions, CCAT providers used ketamine more frequently, consistent with Tactical Combat Casualty Care guidelines. In addition, TBI was the only predictor of vasopressor use and may reflect an attempt to adhere to unmonitored TBI clinical guidelines. Interoperability between CCAT and AE teams is critical to meet mass casualty needs in unregulated mission environments and highlights a need for joint training. It remains imperative to evaluate changes in mission requirements to inform en route combat casualty care training.

Randomized Controlled Trial
Determining Intraosseous Needle Placement Using Point-of-Care Ultrasound in a Swine (Sus scrofa) Model.
Intraosseous (IO) access is critical in resuscitation, providing rapid access when peripheral vascular attempts fail. Unfortunately, misplacement commonly occurs, leading to possible fluid extravasation and tissue necrosis. Current research exploring the utility of bedside ultrasound in confirming IO line placement is limited by small sample sizes of skeletally immature subjects or geriatric cadaveric models. The objective of this study was to investigate the potential value of ultrasound confirming IO needle placement in a live tissue model with bone densities approximated to the young adult medical or trauma patient. ⋯ Within the context of this study, point-of-care ultrasound with CPD did not reliably confirm IO line placement. However, more accurate assessments of functional and malpositioned catheters were noted in sonographers with greater than 4 years of experience. Future study into experienced sonographers' use of CPD to confirm IO catheter placement is needed.
