BMJPublished

  • Retrospective cohort study
  • multicentre registry

Authors' conclusion

This analysis of a large multicenter registry of in-hospital cardiac arrest quantified the time dependent probabilities of patients' outcomes in each minute of duration of cardiopulmonary resuscitation.

Study context

Population
Adults (≥18 years) with index in-hospital cardiac arrest receiving CPR, US multicentre registry, 2000–2021
Participants
348,996 adults
Outcome
Survival to hospital discharge and favourable functional outcome (cerebral performance category 1 or 2) at discharge; time dependent probabilities by minute of CPR duration
Follow-up
Hospital discharge

Main finding

As reported in the abstract

Time dependent probabilities among patients pending ROSC

Survival at 1 minute of CPR (75 645/343 866)

22.0%

Favourable functional outcome at 1 minute of CPR (49 769/328 771)

15.1%

Observational data: associations, not effects.

Further findings

Return of spontaneous circulation and CPR duration

Achieved ROSC: 233 551; median start of chest compressions to ROSC 7 (IQR 3-13) minutes
66.9%
No ROSC: 115 445; median start of chest compressions to termination 20 (14-30) minutes
33.1%

Survival to hospital discharge (overall)

78 799 survived to discharge
22.6%
