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 1st (37.7±12.2 vs 28.2±12.1, P=.15), 2nd (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.
