The International Journal of Emergency Medicine Continuous published an article on a study that evaluates the impact of the American Heart Association's Mission Lifeline initiative on STEMI care in Polk County Fire Rescue (PCFR). By analyzing EMS data from 2015 to 2023, researchers found that Mission Lifeline protocols, such as prehospital 12-lead ECGs and hospital pre-activation, significantly improved EMS-to-balloon (E2B) times and STEMI triage accuracy. The percentage of patients meeting the 90-minute E2B time improved from 74% in 2015 to 84% in 2019, while under-triage rates dropped below 1% after 2020. These findings highlight the effectiveness of standardized, protocol-driven EMS interventions in optimizing STEMI care and improving patient outcomes.
