A desktop systems analysis of critical incidents within a university hospital department of anaesthesia.

INTRODUCTION

Medical error is frequently the result of latent systems factors. Incident reporting systems face many challenges including inability of the system to process reports adequately, inadequate feedback mechanisms and lack of staff engagement especially from doctors. This paper describes a pragmatic physician-led desktop approach to a systems analysis of anaesthesia-related critical incidents which could be used to enhance incident reporting processing within the existing national incident reporting system.

METHODS

Anaesthesiologists within a university teaching hospital were encouraged to report incidents anonymously during the 6-month study period from July 2019 to January 2020. Information was collected on incident details, outcome and preventability. A desktop systems analysis was performed to categorise incidents and to determine contributory factors. Latent errors were considered according to the level of the organisational hierarchy at which they occurred and solutions directed accordingly.

RESULTS

Seventy cases were included giving a reporting rate of 1.76%. Airway/breathing circuit problems (34%) were most frequently cited incidents, followed by other equipment (27%), medication errors (20%) and airway events (19%). The vast majority of events were considered preventable. Most incidents were near misses or of negligible adverse effect with only 6% requiring more than minor treatment. Organisational and strategic contributory factors were identified in 83% of cases, 93% of which were addressable within the department.

CONCLUSION

Implementing local incident reporting systems can be used to complement existing systems at the macro and mesolevel and can be used to improve system processing, create a phased response to latent errors and enhance engagement.
