Background: Trauma education for pediatric residents is limited and suboptimal.
Objective: Test effectiveness and acceptability of interactive, spaced education (ISE) in pediatric trauma.
Methods: Prospective, randomized trial of 40 learners (pediatric residents, fellows, pediatricians) at a Level-1 trauma hospital during 2011-2012. Instrument consisted of 48 multiple-choice questions and answer critiques in audiovisual format based on Trauma Life Support (ATLS) course. Items were divided into 2 modules (24 items each). Instrument was assessed for test-retest reliability, item difficulty and construct validity.
Consenting participants were randomized to 2 cohorts and received a 2-cycle ISE course via a web-based platform over 20 weeks. Each Module was sent as 8 spaced emails (3 questions) over 4 weeks. Percent correct answers were tabulated. First cohort answered Module A, Module B, 4-week rest period followed by Module B and Module A. Second cohort answered Module B, Module A, 4-week rest period followed by Module A and Module B. Primary outcome was difference in mean scores at 2 and 4 months for combined modules for both cohorts among participants who completed the course. T-test and Cohens effect size were performed. Secondary outcome was an exit survey of ISE acceptability as an on-line education method.
Results: Out of 40 enrollees, 1 dropped out before start of program.Thirty-nine learners were randomized to two cohorts; 28 completed follow-up modules at 2 months and 24 completed follow-up modules at 4 months. There was a significant improvement in mean scores at 2 months [8.6 (95% CI: 4.2 - 13.1); effect size: 0.75] but non-significant improvement at 4 months [2.5 (95% CI: -3.6 - 8.6); effect size: 0.18]. Sixty percent of participants would undertake the ISE program again and recommend it to others.
Conclusions: Learning gains in online pediatric trauma education occurred short-term but were not sustained. Most prefer and recommend this form of education to others.
