Consensus on Triple Endoscopy Data Elements Preparatory to Development of an Aerodigestive Registry

Objectives/Hypothesis: This study defines essential data elements to be recorded during an aerodigestive "triple endoscopy" to form the foundation of a standardized multicenter registry and to clearly define measurement of each consensus item. Study Design: Modified Delphi process. Methods: Modified Delphi consensus with six survey rounds. Twenty-four expert pediatric otolaryngology, pulmonology, and gastroenterology aerodigestive clinicians from eight large academic pediatric aerodigestive programs formed the Delphi panel. After achieving consensus through the Delphi process, outside validation was performed at 2019 national Aerodigestive Society conference. Consensus, near-consensus, or exclusion was obtained for each proposed data element. Concordance was then measured between expert panel conclusions and validation group conclusions. Results: Overall response rate was 94.4%. 73/167 proposed items reached consensus in six domains (flexible bronchoscopy, bronchoalveolar lavage, microdirect laryngoscopy and bronchoscopy, esophagogastroduodenoscopy with biopsies, and esophageal impedance and pH probe). Measurement of all items was defined; classification/grading systems were selected for 11 items. Validation group endorsed importance of 82/167 data items; compared to expert consensus, overall, inclusion, and exclusion concordance rates were 94.5%, 98.7%, and 90.9%. Conclusion: Triple endoscopy is a central component of aerodigestive care. This study identifies and defines dat
