Cadaveric Simulation Training Improves Residents' Knowledge and Confidence in Performing Fluoroscopic Guided Joint Injections.

RATIONALE AND OBJECTIVE:Simulation training has been strongly encouraged to enhance radiology trainees' procedural competency. We aimed to assess whether a cadaveric simulation training session was effective in improving radiology residents' subjective technical ability, knowledge and confidence in performing fluoroscopic-guided joint injections. METHODS:As part of the residency program's procedural training curriculum, first year radiology resident participated in a cadaveric, musculoskeletal injection training session including a didactic lecture followed by a practical hands-on component. Trainees performed fluoroscopic guided hip and shoulder injections on fresh cadavers, supervised by two fellowship-trained musculoskeletal radiologists. Trainees' knowledge on indications, contraindications, preprocedural care, complications, and technical ability in performing the procedures, as well as their rating of overall session experience were evaluated with pre- and post-session questionnaires (5 point Likert-scale). The mean residents' scores for pre- and post-session questionnaire items were calculated and compared using paired t-test. The magnitude of difference between mean pre- and post-session scores was compared between the items using analysis of variance. RESULTS:Results Over a 5-year period, 27 trainees participated in the joint injection simulation session. The mean pre- and post-session scores were significantly higher in the post session questionnaire for all five items pertaining to knowledge of indications, contraindications, preprocedural care, complications, and technical ability (all p < 0.0001). The magnitude of improvement was not different between the items (p = 0.45). Most of the participants rated the training facilities, contents, hands-on experience, teaching quality, and session organization as very good or excellent. CONCLUSIONS:Cadaveric joint injection simulation training significantly improved trainees' subjective knowledge, confidence, and technical ability in performing joint injections.
