Cardiac arrest & resuscitation
Comparison of prehospital resuscitation quality during scene evacuation and early ambulance transport in out-of-hospital cardiac arrest between residential location and non-residential location
Authors' conclusion
Deterioration of CPR quality was observed just before and during early ambulance transport, especially when the cardiac arrest location was a residential area or when only manual CPR was provided.
Study context
- Population
- Adults with non-traumatic Out-of-hospital Cardiac Arrest (OHCA) in Seoul, July 2020–March 2022final analysis
- Participants
- 1,222 adults
- Exposure
- Residential vs non-residential cardiac arrest location
- Residentialn = 966
- Outcome
- Prehospital CPR quality indices incl. no-flow (any pause >1.5 s) fraction, at each minute of EMS scene evacuation and early ambulance transport
- Follow-up
- 5 min prior to 5 min after ambulance departure
Methodological detailsPrehospital cardiopulmonary resuscitation (CPR) quality data extracted from defibrillators merged with the national OHCA database
- Prehospital CPR quality data extracted from defibrillators merged with the national OHCA database
Main finding
As reported in the abstract
- CPR quality deteriorated during scene evacuation in both location types
- Mean no-flow fractions significantly higher in residential than non-residential places
- Mean proportion of adequate compression depth and rate lower in residential places
Observational data: associations, not effects.
Further findings
CPR quality by mechanical CPR device use (subgroup)
- Discrepancy in EMS CPR quality during scene evacuation more prominent when mechanical CPR devices not used
