Extracorporeal cardiopulmonary resuscitation (ECPR) eligible refractory out of hospital cardiac arrests – A post-hoc analysis of the EVIDENCE randomised controlled trial and Registry

ResuscitationPublished

  • pre-specified, post-hoc analysis
  • randomised controlled trial (RCT) - EVIDENCE and the contemporaneous EVIDENCE Registry (non-randomised data)

Authors' conclusion

Only a small percentage of OHCA patients were considered eligible for ECPR, predominantly due to challenges in accessing ECPR therapy. ECPR-eligible patients, not treated with ECPR, have very poor survival outcomes.

Study context

Population
Refractory out-of-hospital cardiac arrest (OHCA) patients in the EVIDENCE RCT and RegistryOHCA patients in the combined RCT and Registry
Participants
1,497 participants
Comparison
truly eligible hospital-based ECPR patient vs Potential ECPR patients
  • truly eligible hospital-based ECPR patientn = Thirty-eight

Primary result

As reported in the abstract

Truly eligible for hospital-based ECPR

Thirty-eight of 1497 OHCA patients

3%

Further findings

Main reasons for exclusion of potential ECPR patients

arrival to hospital >1-h post-arrest, arrival to a non-ECPR-capable centre, and/or arrival outside of ECPR-capable hours

Potential ECPR candidates

potential hospital-based ECPR candidates: Seventy-nine
5%
potential pre-hospital ECPR candidates: 350
23%

Survival to hospital discharge of potential ECPR patients

Survival to hospital discharge of potential ECPR patients
5%
