Early defibrillation by basic Emergency Medical Technicians (EMTs) significantly increases survival rates for out-of-hospital cardiac arrest patients. This meta-analysis confirms a 9.2% survival benefit from timely intervention by EMTs.

Area of Science:

  • Emergency medicine
  • Cardiology
  • Public health

Background:

  • Early defibrillation is crucial for out-of-hospital cardiac arrest (OHCA) survival.
  • Existing studies on basic Emergency Medical Technician (EMT) defibrillation vary widely in methodology.
  • Synthesizing diverse research on EMT defibrillation presents interpretation challenges.

Purpose of the Study:

  • To conduct a meta-analysis of published studies on early basic EMT defibrillation.
  • To determine the effect of early basic EMT defibrillation on OHCA patient survival.
  • To statistically evaluate the impact of EMT-delivered defibrillation.

Main Methods:

  • Systematic review and meta-analysis of relevant studies.
  • Inclusion of 10 studies meeting specific criteria.

  • Statistical pooling of data to calculate overall effect size.

    • Main Results:

    • Despite study heterogeneity, a consistent positive effect was observed.
    • The overall effect size was 0.092.
    • Early defibrillation by EMTs demonstrated a 9.2% increase in patient survival.

    Conclusions:

    • Early defibrillation by basic EMTs improves survival outcomes for OHCA patients.
    • Meta-analysis effectively synthesizes varied research findings in this field.
    • Timely intervention by EMT-Defibrillators (EMT-Ds) yields significant survival benefits.
