Abstract
Assessing competency in performing a surgical procedure training is key for instructors to distinguish whether a resident is qualified to perform a surgical procedure. Currently assessment techniques provide a global result and do not provide feedback focused on the procedural stages or on the order in which activities need to be performed. For optimal feedback, it is recommended that it has to be very specific so residents can detect exactly where they are making mistakes in the most objective way possible.
Process Mining is a discipline that generates knowledge from data of the executions of processes registered in information systems, facilitating the analysis of these processes. Since surgical procedures can be understood as a progression of steps, they can be viewed also as a process. In this research, three process-oriented metrics are proposed to generate a more detailed analysis of the variability with which residents carry out their training sessions. This allows obtaining feedback from a global level of the procedure, at a level of stages and finally, at the level of activities.
The research was carried out on the data of a Percutaneous Dilatational Tracheostomy (PDT) surgery training study. Several visualizations were delivered that allow understanding the progress of each resident through their sessions from a process approach. Finally, the behavior of the process-oriented metrics was compared to the classical evaluation methods. In the future, it is expected to be able to validate these metrics for professional use as an evaluation method and as a complement of the current ones.
