The effects of an aviation-style computerised pre-induction anaesthesia checklist on pre-anaesthetic set-up and non-routine events.

This prospective, observational study compared the proportion of cases with missing critical pre-induction items before and after the implementation of an aviation-style computerised pre-induction anaesthesia checklist. Trained observers recorded the availability of critical pre-induction items and evaluated the characteristics of the pre-induction anaesthesia checklist performance including provider participation and distraction level, resistance to the use of the checklist and the time required for completion. Surgical cases that met the criteria for inclusion in the National Surgical Quality Improvement Program at a single academic hospital were selected for observation. A total of 853 cases were observed before and 717 after implementation of the checklist. The proportion of cases with failure to perform all pre-induction steps decreased from 10.0% to 6.4% (p = 0.012). There was also a significant decrease in the proportion of cases with non-routine events from 1.2% cases before to none after checklist implementation (p = 0.003). In 17 cases, the checklist alerted the anaesthesia provider to correct a mistake in pre-induction preparation.
