Cardiac arrest & resuscitation
Barriers to dispatcher-assisted CPR are associated with delayed bystander CPR and worse outcomes in out-of-hospital cardiac arrest: a retrospective cohort study
Authors' conclusion
Barriers to DA-CPR after dispatcher recognition of cardiac arrest were common and associated with delayed bystander CPR and worse outcomes.
Study context
- Population
- Out-of-hospital cardiac arrest (OHCA) emergency calls with dispatcher recognition of cardiac arrest, from 5 OHCA studies linked to the Swedish Registry for CPRconfirmed OHCA
- Participants
- 3,263 participants
- Exposure
- Barrier-present vs Barrier-free
- Outcome
- Bystander CPR initiation, return of spontaneous circulation (ROSC) and 30-day survival
Methodological detailsBayesian modelling, registry-linked
- Bayesian modelling
- Registry-linked
Main finding
As reported in the abstract
Barrier-present vs Barrier-freeAdjusted relative risk (95% CrI)
ROSC; CrI
0.89(0.81–0.98)
30-day survival; CrI
0.57(0.46–0.71)
- Calls with ≥1 barrier
- 43.7%
- Cumulative bystander CPR initiation, barrier-free calls
- 85%
Observational data: associations, not effects.
Further findings
Most common barrier: inability to move the patient (of barrier-present calls)
- Inability to move the patient
- 55.8%
