The effects of bystander interventions for foreign body airway obstruction on survival and neurological outcomes: Findings of the MOCHI registry
Authors' conclusion
Bystander interventions were independently associated with survival and favorable neurological outcome, however, they were performed only in the half of patients.
Study context
- Population
- Patients with foreign body airway obstruction (FBAO) presenting to the ED in Japan, April 2020 to March 2023; median age 82 years (IQR 73–88)analysed
- Participants
- 407 patients
- Exposure
- Bystander FBAO intervention vs no bystander intervention
- Bystander interventionsn = 192
- Outcome
- 1-month survival and favorable neurologic outcome (Cerebral Performance Category 1 or 2)
- Follow-up
- 1 month
Methodological detailsmulticentre, Japan-wide, multivariable logistic regression and Cox proportional hazards adjustment
- Multicentre
- Japan-wide
