Acute cardiac care & resuscitation

How much information is needed to predict outcomes after cardiac arrest?

ResuscitationPublished Retrospective cohort study

Authors' conclusion

Multiple data sources were needed to achieve optimal sensitivity.

Study context

Population
Consecutive adults unresponsive after cardiac arrest, single hospital, January 2010–February 2022773 (70 %) poor outcome
Participants
1,106 participants
Exposure
Machine learning (ML) models using combinations of registry, electronic health record (EHR) and EEG data
Outcome
Sensitivity predicting poor outcome (discharge Cerebral Performance Category (CPC) 4 or 5) at perfect specificity (zero false positives)
Follow-up
Presentation and 12, 24, 48 and 72 h post-arrest
Methodological detailssingle-centre, machine learning prognostic models
  • Single-centre
  • Machine learning prognostic models
