The pediatric echocardiography Boot Camp: Four-year experience and impact on clinical performance.

BACKGROUND

We previously reported on the short-term impact of an echocardiography "Boot Camp" on a single class of cardiology fellows (CF). The impact of the Boot Camp on performance throughout fellowship is unknown.

METHODS

We enrolled four classes of CFs and two classes of cardiac ICU fellows (CVs) prospectively into the Boot Camp and compared CFs to a historical cohort. Experience with echocardiography was surveyed. Outcome measures included written pre- and post-Camp exams, a performance based test (PBT), self-efficacy assessments, numbers of echocardiograms performed, and echocardiogram quality during the last 3 months of fellowship.

RESULTS

A total of 25 CFs and 7 CVs participated in the Boot Camp from July 2012-July 2015. Median experience score was 13/40 (4-23). Median self-efficacy improved from 22/147 (range 21-45) to 90/147 (range 49-133) (P=<.001), and written scores from 14/29 (8-24) to 24/29 (13-29) (P<.001). CFs who completed the Boot Camp performed more independent echocardiograms compared to controls at the end of the 1 (37.7±12.2 vs 28.2±12.1, P=.15), 2 (71.3±24.4 vs 47.6±16.0, P=.044), and third year of fellowship (130.4±44.0 vs 100.0±29.3, P=.230), and on average achieved 150 total echocardiograms in the 4.8th quarter compared to the 7.8th quarter in controls, P=.053. 2D quality scores were higher and shortening fraction more often obtained in echocardiograms performed by Boot Camp CFs compared to controls.

CONCLUSIONS

The pediatric echocardiography Boot Camp improved self-efficacy, acquisition, and retention of echocardiography skills and knowledge, and increased echocardiogram performance. Observed differences between Boot Camp and control CFs appear to wane across fellowship.
