Impact of smartphone activated first responders on provision of bystander CPR, bystander AED and outcomes for out-of-hospital cardiac arrest (OHCA)
Authors' conclusion
We found that the implementation of technology-activated first responders was associated with an improvement in the performance of bystander CPR, bystander AED application, and OHCA outcomes in an urban area.

Main finding
As reported in the abstract
Activated vs Non-activatedAdjusted odds ratio (95% CI)
Bystander CPR
5.69(4.89–6.62)
Bystander AED
2.23(1.82–2.74)
Observational data: associations, not effects.
Secondary outcomes
| Outcome | aOR of 30-day survival with favourable neurological outcome (95% CI) | |
|---|---|---|
