Incentivization to Maximize Retention for Symptom and Activity Monitoring in Pediatric Concussion


In the past, assessment for pediatric concussion injury has occurred at set points in time. A recent study led by PISC Senior Scholar Daniel Corwin, MD, and Executive Committee Member Douglas Wiebe, PhD, featuring Research Coordinator Julia Orchinik, MPH, MS, Senior Scholar, and Past Trainee Bernadette Hohl, PhD, evaluates an alternate incentivization strategy using ecological momentary assessment. The study includes 30 patients aged 13-18 presenting to the ED with concussion. Each patient was randomly assigned a dynamic incentive-based aim or a flat-rate incentive-based aim. Patients reported symptoms 3 times a day, and cognitive abilities once a week. Results indicate that patients with dynamic aims had a retention rate of 68%, while patients with flat aims had a retention rate of 54%. Additionally, no significant differences exist between morning, afternoon, and evening symptoms. The team concludes that “tracking concussed youth using EMA from the ED is feasible using a dynamic incentivization strategy.”
