<p><b><i>Background:</i></b> Standardized training of endobronchial
ultrasound-guided transbronchial needle aspiration (EBUS- TBNA) is
available only in highly developed countries. <b><i>Objective:</i></b> To compare the skill differences in the performance of EBUS-TBNA by pulmonologists trained under different learning methods. <b><i>Methods:</i></b>
We performed a retrospective study of 145 EBUS-TBNA cases. We set up 3
comparative training groups: a standardized training group, a teaching
group, and a self-study group. The main clinical outcomes were
sensitivity, specificity and accuracy of EBUS-TBNA. Cumulative sum
analysis was used to track EBUS-TBNA proficiency of the 3 groups. <b><i>Results:</i></b>
The sensitivities of EBUS-TBNA in the different groups were 90, 88, and
67%, respectively. The accuracies of the different groups were 91, 90,
and 71%, respectively. With respect to the sensitivity and accuracy,
there was no significant difference between the standardized training
group and teaching group. However, the self-study group was inferior to
the other 2 groups. By comparing the learning curve among the groups, we
found that the minimum number of operations needed to reach a 90%
accuracy for the standardized training group, the teaching group and the
self-study group was 17, 32 and 40 cases, respectively. <b><i>Conclusion:</i></b>
Compared with the teaching and self-study groups, the standardized
training group resulted in practitioners achieving high skill levels
following the performance of a lower number of cases. Pulmonologists
trained in the teaching group achieved a similar level of skills, but
required more experience to reach this level. Practitioners in the
self-study group did not achieve a satisfactory level of skills, despite
performing a high number of cases.</p>
