Recent coronavirus disease 2019 (COVID-19) events have presented challenges to health care systems worldwide. Air medical movement of individuals with potential infectious disease poses unique challenges and threats to crews and receiving personnel. The US Department of Health and Human Services air medical evacuation teams of the National Disaster Medical System directly supported 39 flights, moving over 2,000 individuals. Infection control precautions focused on source and engineering controls, personal protective equipment, safe work practices to limit contamination, and containment of the area of potential contamination. Source control to limit transmission distance was used by requiring all passengers to wear masks (surgical masks for persons under investigation and N95 for known positives). Engineering controls used plastic sheeting to segregate and treat patients who developed symptoms while airborne. Crews used Tyvek (Dupont Richmond, VA) suits with booties and a hood, a double layer of gloves, and either a powered air-purifying respirator or an N95 mask with a face shield. For those outside the 6-ft range, an N95 mask and gloves were worn. Safe work practices were used, which included mandatory aircraft surface decontamination, airflow exchanges, and designated lavatories. Although most patients transported were stable, to the best of our knowledge, this represents the largest repatriation of potentially contagious patients in history without infection of any transporting US Department of Health and Human Services air medical evacuation crews.

Helicopter Transport Has Decreased Over Time and Transport From Scene or Hospital Matters.
Several reports have found helicopter emergency medical services (HEMS) to be associated with a lower risk of mortality compared with ground emergency medical services (GEMS); however, most studies did not control for transport time or stratify interfacility versus scene. We hypothesize that the HEMS transport rate has decreased nationally and that the risk of mortality for HEMS is similar to GEMS when adjusting for transport time and stratifying by scene or interfacility. ⋯ The rate of HEMS transports in trauma has decreased by nearly 40% over the past 7 years. Our results suggest that HEMS use for scene transports is beneficial for the survival of trauma patients.

Case ReportsUnattended Hoist Extraction of an Intubated Patient From Mountainous Terrain.
Airway management and maintenance of adequate ventilation during a patient's unattended helicopter rescue hoist extraction present unique challenges to the air medical provider. We present the case of a critically injured patient requiring emergent airway management and subsequent extrication via hoist from challenging, near-vertical terrain, which illustrates the logistical challenges of providing high-quality, neuroprotective mechanical ventilation in an austere air medical scenario.
