Randomized Controlled Trial of Interactive Spaced Education to Support Constipation Management by Pediatric Primary Care Providers

Introduction: Integrating continuing medical education and quality improvement (QI) initiatives is challenging. We aimed to compare one method, Interactive Spaced Education (ISE/QI), with standard (sTD/Qi) education embedded within a constipation management Qi initiative. Methods: We conducted a randomized, controlled study to compare ISE/QI and STD/QI education. Pediatric primary care providers (PCPs) were recruited from a network of local private practices. The QI initiative was implemented with all providers before education interventions. ISE/QI participants received questions by email weekly, provided answers, received feedback, and repeated questions over a 4-month period. The STD/QI group received a Power Point with the same educational content. Pre- and post-surveys evaluated usability, self-assessed confidence, and practice changes while quizzes evaluated knowledge. Process control charts tracked subsequent visits to gastroenterology (GI). Results: Of the 212 eligible PCPs, 101 (48%) enrolled, with 49 PCPs in the ISE/QI arm and 52 in STD/QI education arm. Quiz scores improved in the ISE/QI arm with a strong effect size (Cohen d 1.76). Mean increase in confidence managing difficult cases was higher in the ISE/QI group (1.84 vs 1.21, P = 0.030). ISE/QI participants were more likely to rate the activity better than most online education (odds ratio [OR] 18.1, P < 0.0001) and incorporate practice changes (OR 3.35, P = 0.0152). Visits to GI decreased among the entire population, but the effect on GI visits within each education arm was mixed. Conclusions: ISE/QI improved knowledge and confidence managing difficult cases. ISE/QI participants reported higher likelihood to change practice, but no differences were seen in GI referrals.
