Cf. Mackenzie et al., COMPARISON OF SELF-REPORTING OF DEFICIENCIES IN AIRWAY MANAGEMENT WITH VIDEO ANALYSES OF ACTUAL PERFORMANCE, Human factors, 38(4), 1996, pp. 623-635
We compared the performance deficiencies of airway management captured
by three types of self-reports with those identified through video an
alysis. The three types of self-reports were the anesthesia record (a
patient record constructed during the course of treatment), the anesth
esia quality assurance (AQA) report (a retrospective report as a part
of the trauma center's quality assurance process), and a posttrauma tr
eatment questionnaire (PTQ), which was completed immediately after the
case for the purposes of this research. Video analysis of 48 patient
encounters identified 28 performance deficiencies related to airway ma
nagement in 11 cases (23%). The performance deficiencies took the form
of task omissions or practices that lessened the margin of patient sa
fety. In comparison, AQA reports identified none of these performance
deficiencies, the anesthesia records identified 2 (of 28), and the PTQ
s suggested contributory factors and corrective measures for 5 deficie
ncies. Furthermore, video analysis provided information about the cont
ext of and factors contributing to the identified performance deficien
cies, such as failures in adherence to standard operating procedures a
nd in communications.
