Background:
Literature supports the use of point-ofcare ultrasound performed by the treating hospitalist in the diagnosis of common diseases. There is no consensus on the training paradigm or the evaluation of skill retention for hospitalists.
Objective:
To evaluate the effectiveness of a comprehensive bedside ultrasound training program with postcourse competency assessments for hospitalists.
Design:
A retrospective report of a training program with 53 hospitalists. The program consisted of online modules, a 3-day in-person course, portfolios, 1-day refresher training, monthly scanning, and assessments. Hospitalists were rated by using similar pre- and postcourse competency assessments and self-rating parameters during the 3-day and refresher courses.
Setting:
A large tertiary-care center.
Results:
Skills increased after the 3-day course from a median preassessment score of 15% correct (interquartile range [IQR] 10%-25%) to a median postassessment score of 90% (IQR 80%-95%; P < .0001). At the time of the refresher course, the median precourse skills score had decreased to 65% correct (IQR 35%-90%), which improved to 100% postcourse (IQR 85%-100%; P < .0001). Skills scores decreased significantly less between the post 3-day course assessment and pre 1-day refresher course for hospitalists who completed portfolios (mean decrease 13.6% correct; P < .0001) and/or monthly scanning sessions (mean decrease 7.3% correct; P < .0001) compared with hospitalists who did not complete these items.
Conclusions:
A comprehensive longitudinal ultrasound training program including competency assessments improved ultrasound acquisition skills with hospitalists. Skill retention remained high in those who completed portfolios and/or monthly scanning sessions along with a 1-day in-person refresher course.
