Cardiac arrest & resuscitation

Diagnostic yield of computed tomography after non-traumatic out-of-hospital cardiac arrest

ResuscitationPublished Retrospective cohort study

Authors' conclusion

CT identifies clinically important pathology after OHCA.

Study context

Population
Non-traumatic out-of-hospital cardiac arrest (OHCA) patients treated at a single centre, February 2019 to February 2021
Participants
480 / 230 / 410 / 363
Exposure
Computed tomography (CT) head vs Cervical spine CT vs Chest CT vs Abdomen and pelvis CT
  • CT headn = 480
  • Cervical spine CTn = 230
  • Chest CTn = 410
  • Abdomen and pelvis CTn = 363
Outcome
Frequency of clinically important findings on CT after OHCA
Follow-up
Within 24 hours of ED arrival
