Outcomes Following Impedance Threshold Device Use During Out-of-Hospital Cardiac Arrest

ResuscitationPublished

  • nationally representative sample
  • multivariate logistic regression
  • adjusting for demographics and several potential confounders

Authors' conclusion

ITD use was associated with improved prehospital outcomes but worsened dispositional outcomes among patients experiencing OHCA, suggesting this device may prove beneficial early in resuscitation of OHCA patients.

Study context

Population
Adult, non-traumatic, OHCA scene runs from the 2024 ESO Data Collaborativepatient records, disposition outcomes available for 13,026 patients (23.3%)
Participants
97,439 participants
Comparison
Impedance threshold device (ITD) only; ITD+ACD; neither device
  • ITD onlyn = 13.1%
  • ITD+ACDn = 1.6%
  • no ITDn = 85.3%reference

a similar pattern emerged for favorable neurologic outcome

ITD+ACD group

The ITD+ACD group showed more extreme versions of the trends observed for ITD only
