Objective: This study assessed the impact of a blended, standardized curriculum for invasive bedside procedural training on medical knowledge and technical skills for Internal Medicine residents. Methods: The investigators developed a curriculum in procedural instruction and performance for Internal Medicine house staff, and implemented the program at a tertiary care academic medical center with a primary affiliation with a US medical school. The investigators chose procedures recommended for technical competence by the American Board of Internal Medicine: lumbar puncture, thoracentesis, paracentesis, central venous catheter insertion, and knee arthrocentesis. The program included: (1) assessment of baseline medical knowledge and technical proficiency on mannequins, (2) video instruction of procedure, (3) faculty-led discussion of critical concepts, (4) faculty demonstration of the procedure on mannequin, (5) individual practice on simulators, (6) post-intervention knowledge evaluation, and (7) post-intervention skills evaluation. The performance achieved during the initial skills evaluation on a mannequin was compared to the performance achieved on the first patient subsequent to the instructional portion. Results: All participants with complete data demonstrated a statistically significant pre-intervention to post-intervention improvement (p < 0.05) in comprehensive medical knowledge and procedural skills. Conclusion: A blended, standardized curriculum in invasive bedside procedural instruction can significantly improve performance in participants' medical knowledge and technical skills.
