Acute cardiac care & resuscitation
Diagnostic performance of a video-assisted cardiac arrest recognition protocol by emergency medical dispatcher in out-of-hospital cardiac arrest
Authors' conclusion
Use of video-assisted cardiac arrest recognition protocol helped recognize additional cardiac arrest cases that could not be recognized with the audio-call in the dispatch center.
Study context

- Emergency calls to the Seoul emergency dispatch center with uncertain cardiac arrest recognition on audio call, June–December 2020
- Participants
- 115 emergency calls
- Outcome
- Presence of cardiac arrest upon EMS arrival, evaluated by EMS providers at the scene
Methodological detailssingle dispatch centre, pilot implementation
- Single dispatch centre
- Pilot implementation
Performance
As reported in the abstract
Diagnostic performance for cardiac arrest
| Test or model | Sensitivity | Specificity |
|---|---|---|
| Video-assisted protocol | 66.7 % (95% CI 43.0-85.4) | 98.9 % (95% CI 94.2-100) |
Video-assisted protocol
Sensitivity66.7 % (95% CI 43.0-85.4)
Specificity98.9 % (95% CI 94.2-100)
Further findings
Cases recognised as cardiac arrest under video-assistance confirmed as cardiac arrest on emergency medical service (EMS) arrival
- Recognised cases (15) confirmed as cardiac arrest on EMS arrival
- 14 (93.3 %)
