Cardiac arrest & resuscitation
Effects of a volunteer responder system for out-of-hospital cardiac arrest in areas of different population density – A retrospective cohort study
Authors' conclusion
Volunteer responders have significantly shorter response time than EMS regardless of population density, with the greatest difference in low population density areas.
Study context
- Population
- Suspected OHCAs in Stockholm County, 2018–2020, where ≥1 dispatched volunteer responder reached the patient
- Participants
- 2,630 suspected OHCAs
- Exposure
- Volunteer responders vs EMS
- Outcome
- Proportion of cases where volunteer responders arrived before EMS, and difference in arrival time between volunteer responders and EMS
Main finding
As reported in the abstract
Volunteer responders arriving before EMS
Volunteer responders
68%
1613 events
- Time on scene before EMS arrival highest in low population density areas, averaged
- 4:07 (mm:ss)
Observational data: associations, not effects.
Further findings
| Outcome | Volunteer responders | EMS | P value |
|---|---|---|---|
| Response timeSignificantly shorter across all population density groups | 4:47 mm:ss | 8:11 mm:ss | P < 0.001 |
Response time
- Largest difference in response time in low population density areas
