We compared the performance deficiencies of airway management captured by three types of self-reports with those identified through video analysis. The three types of self-reports were the anesthesia record (a patient record constructed during the course of treatment), the anesthesia quality assurance (AQA) report (a retrospective report as a part of the trauma center's quality assurance process), and a posttrauma treatment questionnaire (PTQ), which was completed immediately after the case for the purposes of this research. ⋯ In comparison, AQA reports identified none of these performance deficiencies, the anesthesia records identified 2 (of 28), and the PTQs suggested contributory factors and corrective measures for 5 deficiencies. Furthermore, video analysis provided information about the context of and factors contributing to the identified performance deficiencies, such as failures in adherence to standard operating procedures and in communications.
