PURPOSE: To examine the efficacy of a one day course in educating an international group of physicians in endobronchial ultrasound transbronchial needle aspiration (EBUS TBNA).
METHODS: 40 physician participants were given a 12 question multiple choice exam of the basic principles of EBUS TBNA. Exams were administered before and after attending a focused lecture series and hands-on low and high fidelity simulation training. A descriptive analysis was performed to summarize participant characteristics. The distributions of the percentage of correct answers both before and after training were assessed. A Wilcoxon signed ranked sum test to compare percentage of correct responses in both periods was utilized.
RESULTS: Six participants were excluded from the analysis due to incomplete examinations. Pulmonary/Critical Care physicians made up 87.5 % of the participants with years out of fellowship ranging from 0 to greater than 20 years. Fifty-two percent of the attendees had been trained in conventional TBNA. Forty-five percent were in an academic practice setting. There were 77.5% of the group who had performed at least 200 bronchoscopies and 47.5% had performed 40 conventional TBNAs. In contrast, 52.5% had performed no EBUS TBNA and 30% had performed 5 or less prior to participating in the one day course. Participants lacked EBUS training: 67.5% had no prior audiovisual or didactic EBUS training, 77.5% had no solo hands-on training, and 52.5% had no mentored hands-on EBUS training. Survey responses indicated 77.5% were "not confident" in their EBUS TBNA skills. The median percent of correct responses prior to training was 62% compared to 85% after training. This was statistically significant at a p-value of < 0.001 for the signed rank sum test.
CONCLUSION: A combination of didactics and simulator exercises with specific objectives can significantly increase physician knowledge regarding EBUS TBNA.
CLINICAL IMPLICATIONS: This builds a foundation for further research to better assess the "best way" to transfer knowledge and performance competency in EBUS TBNA in a safe and efficient format that translates to clinical outcomes in the bronchoscopy suite.
