Constructing hierarchical task analysis in surgery

Abstract

This study outlines a valid and reliable method of constructing a surgical task analysis and HTA for any operation or procedure, which could be used to assess and evaluate trainees' and expert surgeons' specific technical skills.

Standardization of surgical procedures for identifying best practices and training.

“…A taxonomy was developed using traditional hierarchical task analysis, HTA, methods described by [4,7,8,11]. The particular study focused on microvascular surgical anastomoses, but many of the tools and findings can be generalized to other types of surgical and clinical procedures Development of the taxonomy was an iterative process in which HTAs were applied to observed cases.…”

A systematic review of performance assessment tools for laparoscopic cholecystectomy

“…Within technical skills assessment tools, two hybrid tools developed by Sarker et al (Sarker's Global Rating Scale and PBA) and the observation clinical human reliability assessment (OCHRA; PA) which is an error rating tool were developed based on task analyses using training manuals and the technical protocol of the operation [19,21]. The other tools were developed by expert judgment including institutional expert panels.…”

Surgical Education

“…The system was designed based on the hierarchical task analysis mentioned above (Sarker et al 2008), as well as in continuous correspondence with expert surgeons and observations made in the operating theatre. Using the HTA as a foundation, we compiled an implementation plan detailing (A) the virtual environment, (B) the user interactions and (C) the requirements of deformable models.…”
