Cardiac arrest & resuscitation
The association of clinical, treatment, and demographic characteristics with rearrest in a national dataset
Authors' conclusion
This multiagency retrospective study found that factors associated with increased ischaemic burden following OHCA were associated with rearrest. Agency-level rearrest frequency was inversely associated with agency-level survival to home.
Study context
- Population
- Adults with non-traumatic OHCA achieving ROSC after EMS resuscitation, ESO datasets 2018–2021
- Participants
- 53,027 adults
- Outcome
- Prehospital rearrest (post-ROSC CPR, ≥ 1 mg adrenaline, defibrillation, or non-perfusing rhythm on hospital arrival)
