The Taiwan ED Airway Quality Surveillance Registry (TEAR): A Prospective Multicenter Observational Study

This prospective, multicenter observational registry systematically captures all emergency department tracheal intubations across participating hospitals in Taiwan. The registry focuses on process quality indicators, including first-pass success, and patient-safety outcomes, including hypoxemia, hypotension, and peri-intubation cardiac arrest within 30 minutes of intubation. Routinely generated laboratory and physiologic variables are also collected to improve risk stratification and identify predictors of major adverse events. The study is non-interventional and does not alter clinical care.
