Latent safety threats (LSTs) identified using movement tracking

Comparative impact of LSTs between sessionsLST
Role within the trauma team and task allocationParticipant 1 retrieved all equipment without help from team members while participants 2 and 3 delegated equipment retrieval to a variable extentDelegation of equipment retrieval to the individual tasked with performing a cricothyroidotomy
Knowledge of clinical space: trauma room layout and equipment locationParticipant 1 had minimal familiarity with the equipment location resulting in inefficient movement while participant 2 was more familiar with the workspace resulting in a direct path to retrieve sterile gloves
Participant 3 waited at the head of the bed while team members brought equipment to the bedside
The equipment for the open surgical technique was located far from the bedside while the bundled Seldinger kit was near the head of the bed
Knowledge gaps related to the location of essential equipment
Location of cricothyroidotomy equipment and supplies far from the bedside
Equipment bundlingThe traditional open surgical cricothyroidotomy equipment used in sessions 1 and 2 was not bundled; the equipment was spread throughout the trauma room
The percutaneous Seldinger technique used in session 3 was bundled (ie, kept in a prepackaged kit)
Cricothyroidotomy equipment spread throughout the trauma room
