Cardiac arrest & resuscitation

Does the initial description of an out-of-hospital cardiac arrest given by callers contacting Emergency Medical Services contain key indicator words which can be used to support appropriate resource deployment?

ResuscitationPublished Retrospective cohort study

Authors' conclusion

Analysis of information volunteered by an EMS caller may be able to predict clinical outcome, particularly for patients who have resuscitation withheld on EMS arrival.

Study context

Population
Out-of-hospital cardiac arrest (OHCA) calls to a single English Emergency Medical Services (EMS), 01/04/2020–31/03/2023
Participants
37,532 OHCA electronic health records
Outcome
Terms in callers' initial descriptions associated with patient clinical outcome:
  • Resuscitation withheld
  • Survival to 30 days
Follow-up
30 days
Methodological detailssingle EMS, linked call data and clinical records
  • Single EMS
  • Linked call data and clinical records

Main finding

As reported in the abstract

'Lifeless' descriptors with stronger association with resuscitation being withheld
13
Calls with 'Lifeless' descriptors still receiving the highest level of EMS response
56.6%
Terms with better association with survival to 30 days (often symptoms, e.g. "chest pain", "sweating")
4
Chi-square significance for both subgroups
p < 0.001

Observational data: associations, not effects.
