Background: Air ambulance services are commonly used to expedite interfacility transport of injured patients to trauma centers. There is a lack of evidence surrounding risk factors for delays in interfacility transport of these patients. The purpose of this study was to examine patient, paramedic, and institutional-related characteristics for delay and identify specific causes of delays in interfacility transfers by air ambulance. ⋯ Third, interfacility transport times are heavily skewed and delays disproportionately affect longer patient transports. Conclusions: Ventilator dependence, paramedic level of care, classification of sending facility and helipad availability are associated with delays to interfacility transport of injured patients. Efforts can be made at both the air ambulance and institutional levels to ensure timely and efficient transports.

Background: Analgesics, sedatives, and neuromuscular blockers are commonly used medications for mechanically ventilated air medical transport patients. Prior research in the emergency department (ED) and intensive care unit (ICU) has demonstrated that depth of sedation is associated with increased mechanical ventilation duration, delirium, increased hospital length-of-stay (LOS), and decreased survival. The objectives of this study were to evaluate current sedation practices in the prehospital setting and to determine the impact on clinical outcomes. ⋯ No association existed between either specific medications or depth of sedation and the development of delirium. Conclusions: Prehospital moderate and deep sedation, as well as benzodiazepine administration, is associated with increased hospital LOS. Our findings point toward sedation being a modifiable risk factor and suggest an important need for further research of sedation practices in the prehospital setting.

Objective: To investigate the impact of epinephrine on prehospital rearrest and re-attainment of prehospital return of spontaneous circulation (ROSC). Methods: Data for 9,292 (≥ 8 years) out-of-hospital cardiac arrest (OHCA) patients transported to hospitals by emergency medical services were collected in Ishikawa Prefecture, Japan during 2010-2018. Univariate and multivariable analyses were retrospectively performed for 1,163 patients with prehospital ROSC. ⋯ Transportation to hospitals with a unit for post-resuscitation care was associated with better neurological outcome (adjusted OR: 1.53, 95% CI: 1.02-2.32). Conclusions: The requirement for epinephrine administration before prehospital ROSC was associated with subsequent rearrest. Routine epinephrine administrations and rearrest were associated with poorer neurological outcome of OHCA patients with prehospital ROSC.
