Abstract
OBJECTIVE: There is significant variation in out-of-hospital cardiac arrest (OHCA) outcomes between different regions. We sought to evaluate outcomes of OHCA patients in the interfacility transfer (IFT) setting, between critical care transport (LifeFlight) and community Emergency Medical Services (EMS), in the state of Maine. METHODS: This was a retrospective analysis of our institution's electronic medical record and the Maine EMS database. Data were collected from January 1, 2019, to December 31, 2021. Only adult OHCA encounters requiring an IFT for definitive post-cardiac-arrest care were included. Demographics, EMS agency, IFT vital signs, targeted temperature management (TTM) medications, cerebral performance category (CPC) scores, survival to discharge, and other descriptive variables were collected. RESULTS: Ninety-three patients met inclusion criteria, with LifeFlight transferring 30 of them (32.3%). LifeFlight was more likely to initiate TTM compared to other EMS agencies (p = 0.012), have run-sheets reported (p = 0.001), and serve rural areas (p = 0.036). LifeFlight was associated with more epinephrine (0.034) and norepinephrine (<0.001) use. Only 37% of IFTs had physician orders, with none (0.0%) of them defining vital sign targets. No difference in survival to discharge or CPC scores was observed between LifeFlight and other EMS agencies. No significant variation in comorbidities or vital signs was observed. CONCLUSIONS: There was no difference in survival to discharge or CPC scores between LifeFlight and ad hoc EMS agency. LifeFlight was associated with more TTM and vasopressor utilization during IFT. Most IFT encounters did not have dedicated physician orders, and none of the orders included vital sign targets.
