Validation of the quality of ultrasound imaging and competence (QUICk) score as an objective assessment tool for the FAST examination.

Background: The Focused Assessment with Sonography for Trauma (FAST) examination has become a valuable tool in trauma resuscitation. Despite the widespread use of FAST training among traumatologists, no evidence-based guidelines exist to support optimal training requirements or to provide quantitative objective assessments of imaging capabilities. Both Task-Specific Checklist (TSC) and Global Rating Scale (GRS) have been validated as objective skill assessment tools; we developed both types of scoring checklist and assessed them for construct validity with the FAST examination.

The effect of blocked versus random task practice schedules on the acquisition and retention of surgical skills.

Background: When learning multiple tasks, blocked or random training schedules may be used. We assessed the effects of blocked and random schedules on the acquisition and retention of laparoscopic skills.

Methods: Thirty-six laparoscopic novices were randomized to practice laparoscopic tasks using blocked, random, or no additional training.

Design and Validation of 3D Printed Complex Bone Models with Internal Anatomic Fidelity for Surgical Training and Rehearsal.

Physical models of complex bony structures can be used for surgical skills training. Current models focus on surface rendering but suffer from a lack of internal accuracy due to limitations in the manufacturing process. We describe a technique for generating internally accurate rapid-prototyped anatomical models with solid and hollow structures from clinical and microCT data using a 3D printer.

Construct validity of individual and summary performance metrics associated with a computer-based laparoscopic simulator.

Background: Computer-based surgical simulators capture a multitude of metrics based on different aspects of performance, such as speed, accuracy, and movement efficiency. However, without rigorous assessment, it may be unclear whether all, some, or none of these metrics actually reflect technical skill, which can compromise educational efforts on these simulators. We assessed the construct validity of individual performance metrics on the LapVR simulator (Immersion Medical, San Jose, CA, USA) and used these data to create task-specific summary metrics.

Generation of a 3D printed temporal bone model with internal fidelity and validation of the mechanical construct.

Objective: To generate a rapid-prototyped temporal bone model from computed tomography (CT) data with a specific focus on internal anatomic fidelity.

Study Design: Research ethics board-approved prospective cohort study.

Setting: Current iterations of a rapid-prototyped temporal bone model are complicated by absent void spaces and inconsistent bone density due to limited infiltrant exposure.
