Airway obstruction time and outcomes after foreign body airway obstruction: a nationwide prospective cohort study from the MOCHI registry
- secondary analysis of the nationwide, prospective MOCHI registry
- multivariable logistic regression and spline models
Authors' conclusion
Outcomes declined continuously per minute of unresolved obstruction, with no inflection point or "safe" time window. This highlights that every minute of delay worsens prognosis, reinforcing the need for immediate bystander intervention.
Study context
- Population
- Patients with foreign body airway obstruction (FBAO) in Japan, airway obstruction times of 0–25 min229 met the primary inclusion criteria
- Participants
- 409 patients
- Comparison
- Odds ratios per 1-min increase in airway obstruction time
- Primary endpoint
- Survival
- Follow-up
- 30-day
Primary result
As reported in the abstract
Adjusted odds ratio
0.86
95% CI 0.81–0.90
per 1-min increase in obstruction duration
aOR 0.86 (95% CI 0.81–0.90)
Per 1-min increase in obstruction duration, as printed
- Survived to 30 days
- 60%
Secondary outcomes
| Outcome | aOR (95% CI) | |
|---|---|---|
| Favorable neurological outcome (Cerebral Performance Category 1-3), secondary outcome · 30-day · lower odds with longer obstruction | 0.85 (0.80–0.89) | |
| 0.512Adjusted odds ratio (log scale) |
- Favorable neurological outcome (Cerebral Performance Category 1-3), secondary outcome — Favorable neurological outcome
- 47%
Predicted outcomes by obstruction time (spline models)
- Steep monotonic decline from onset without evidence of a distinct threshold or "safe" time window
Baseline characteristics
