Methodological quality and transparency of clinical practice guidelines for difficult airway management using the appraisal of guidelines research & evaluation II instrument: A systematic review.

Background: Complications arising from airway management represent an important cause of morbidity and mortality. Clinical practice guidelines (CPGs) are systematically created documents that summarise knowledge and assist the delivery of high-quality medical care by identifying evidence that supports best clinical care.

Objective: Using the Appraisal of Guidelines for Research & Evaluation II instrument, we aimed to evaluate the methodological rigour and transparency of unanticipated difficult airway management CPGs in adults.
