OBJECTIVE: Hemorrhage identification in trauma care is a major priority. Focused assessment in sonography for trauma (FAST) offers a rapid, reliable means of detecting torso bleeding. The aims of this study were to conduct a face, content, and construct validity assessment of a FAST simulator and establish a rigorous assessment tool.
DESIGN: Participants were requested to perform a FAST scan and state if any abnormality was found in each region. Metrics evaluated included time, errors, and missed targets. Accuracy of images obtained was assessed by 2 independent radiologists. Experts completed a face and content validity questionnaire at the end of the study.
SETTING: The study took place in the simulation suite within the Academic Surgical Unit of the Department of Surgery and Cancer.
PARTICIPANTS: Novices had no prior experience with ultrasound, intermediates had less than 6 months experience with fewer than 50 FAST scans performed, and experts had more than 1 year of experience with greater than 100 FAST scans performed. There were 31 participants: 11 experts, 10 intermediates, and 10 novices.
RESULTS: The face and content validity questionnaire scored high marks across all categories and achieved an overall median realism score of 8 ± 1.5 on a Likert scale. Experts performed the FAST scan faster with more accuracy and fewer errors than other cohorts (p < 0.001). Both the novices and intermediates were the slowest, least accurate, and either missed or made the most errors when scanning the lung bases and spleen.
CONCLUSIONS: This study has established the face, content, and construct validities of a FAST simulator, which could be used to accelerate training for novices. Additionally, it has demonstrated a rigorous method for FAST assessment, which has proven to be effective and in doing so addressed some of the criticisms leveled against it.
