Harnessing In Situ Simulation to Identify Human Errors and Latent Safety Threats in Adult Tracheostomy Care

Abstract

Background: Tracheostomies are associated with high rates of complications and preventable harm. Safe tracheostomy management requires highly functioning teams and systems, but health care providers are poorly equipped with tracheostomy knowledge and resources. In situ simulation has been used as a quality improvement tool to audit multidisciplinary team emergency response in the actual clinical environment where care is delivered but has been underexplored for tracheostomy care.

Methods: From July 2021 to May 2022, the study team conducted in situ simulations of a tracheostomy emergency scenario at Montefiore Medical Center to identify human errors and latent safety threats (LSTs). Simulations included structured debriefs as well as audiovisual recording that allowed for blind rating of these human errors and LSTs. Provider knowledge deficits were further characterized using pre-simulation quizzes.

Results: Twelve human errors and 15 LSTs were identified over 20 simulations with 88 participants overall. LSTs were divided into the following categories: communication, equipment, and infection control. Only 50.0% of teams successfully replaced the tracheostomy tube within the scenario's five-minute time limit. In addition, knowledge gaps were highly prevalent, with a median pre-simulation quiz score of 46% (interquartile range 36-64) among participants.

Conclusion: An in situ simulation-based quality improvement approach shed light on human errors and LSTs associated with tracheostomy care across multiple settings in one health system. This method of engaging frontline health care provider key stakeholders will inform the development, adaptation, and implementation of interventions.
