Acute cardiac care & resuscitation
Expedited conveyance of out-of-hospital-cardiac arrest patients with STEMI and shockable rhythms to Cardiac Arrest Centres − A feasibility pilot study of the British Cardiovascular Intervention Society conveyance algorithm
Main finding · Death from any causeResult — go to the resultRelative risk 1.10 95% CI 0.98–1.24Authors' conclusion
The BCIS algorithm is feasible and did not impact overall mortality, but there is signal that direct conveyance of OHCA patients with an initial shockable rhythm and low MIRACLE2 score, to a dedicated CAC may improve survival.
Study context
- Population
- Patients with out-of-hospital cardiac arrest (OHCA) from suspected cardiac aetiology from the county of Essex, United Kingdom, April 2022-April 2023mean age 67.5 ± 13.1, 66% male
- Participants
- 330 patients
- Exposure
- BCIS conveyance algorithm vs conveyance as standard of care
- Standard care groupn = 162
- BCIS conveyance groupn = 168reference
- Outcome
