Prehospital prognostication after out-of-hospital cardiac arrest in tertiary care centers: the R-EDByUS score in the JAAM-OHCA registry
Authors' conclusion
The R-EDByUS score showed good discrimination in the JAAM-OHCA Registry, supporting its use for early risk stratification in cardiogenic OHCA even in tertiary care centers.
Study context
- Population
- Adult patients with presumed cardiogenic out-of-hospital cardiac arrest transported to tertiary care centers, JAAM-OHCA Registrypatients analyzed · prehospital return of spontaneous circulation (ROSC) cohort 3,305 · ongoing cardiopulmonary resuscitation (CPR) cohort 26,040
- Participants
- 29,345 patients
- Comparison
- R-EDByUS score predictions of unfavorable neurological outcome (Cerebral Performance Category 3-5) at 1 month
- Prehospital ROSC cohortn = 3,305
- Ongoing CPR cohortn = 26,040
- Outcome
- Discrimination for unfavorable neurological outcome (Cerebral Performance Category 3-5)
- Follow-up
- 1 month
Methodological detailsregistry-based

Performance
As reported in the abstract
Areas under the curve
0.906 and 0.913
Further findings
Unfavorable outcomes among patients with a predicted probability ≥99%
Calibration
- Good calibration in the prehospital ROSC cohort
Discrimination across in-hospital intervention subgroups (subgroup)
- Discrimination was lower among patients who received PCI, TTM, or ECMO in the ongoing CPR cohort
