BACKGROUND
• Emergency medicine is increasingly recognized as a medical specialty in Japan,
• Comprehensive studies evaluating emergency airway management practice are lacking.
![Page 4: Emergency Airway Management in Japan: a Multi-center Prospective Observational Study](https://reader036.vdocuments.us/reader036/viewer/2022062410/568164a6550346895dd69617/html5/thumbnails/4.jpg)
OBJECTIVES
To describe – emergency intubation indications– methods used to intubate– success rates– adverse event rates
![Page 5: Emergency Airway Management in Japan: a Multi-center Prospective Observational Study](https://reader036.vdocuments.us/reader036/viewer/2022062410/568164a6550346895dd69617/html5/thumbnails/5.jpg)
METHODSStudy Design
• a prospective observational multi-center data registry– with all data collection planned a priori
• IRB of each center has approved the protocol, with waiver for informed consent.

Study Setting
• the Japanese Emergency Airway Network (JEAN)– a consortium of 10 academic & community ED
• 9 affiliated with EM residency• Level I (n=9) or Level II equivalent (n=1) trauma
• an average ED census of 27,000 patient visits/y– range, 9,000 to 42,000

Selection of Participants
• Eligible for inclusion:– All patients who presented to 10 EDs and– Underwent endotracheal intubation
• Gathered prospectively during an 11-month period – April 2010 to February 2011
![Page 8: Emergency Airway Management in Japan: a Multi-center Prospective Observational Study](https://reader036.vdocuments.us/reader036/viewer/2022062410/568164a6550346895dd69617/html5/thumbnails/8.jpg)
Measurements
• We report information about the distribution of:1. Indications for intubation.2. Methods used to intubate.3. Success rate of intubation by method.4. Adverse event rates
Using simple descriptive statistics.

RESULTS
• For the 11-month pilot period,
• 1,490 eligible patients.
• Database recorded 1,486 intubations (compliance rate 99.7%).

DISCUSSIONpractice variations
• We are struck by a high degree of variations in airway management practices among sites.
• Because of the non-controlled nature of this study, the reasons for this variation are not well defined.– Confounding by indication?– Physician’s preference?

Variations in Success
The variability in the method of intubation may, in part, account for this variation
Potentially confounded by unmeasured variables
Assuming validities of our observations, this study hints at the need for efforts toimprove ED airway management quality.

LIMITATIONS
• Reporting bias• Outcomes not measured• Unmeasured confounders• External validity
![Page 18: Emergency Airway Management in Japan: a Multi-center Prospective Observational Study](https://reader036.vdocuments.us/reader036/viewer/2022062410/568164a6550346895dd69617/html5/thumbnails/18.jpg)
CONCLUSIONS
• a high overall intubation success rate• a high degree of variations among hospitals in
emergency airway management.
• Our study provides a starting point to improve the quality of airway management.
