Project PREVENT: A Randomized, Controlled Trial of Web-Based Video Education to Improve Uptake of Preventive Health Recommendations in Adults with Inflammatory Bowel Disease
ABSTRACT
Background/Aims: Inflammatory bowel disease (IBD) patients are at increased risk of infections, bone fractures and skin cancers. We developed preventive health videos using a patient-centered approach, and tested their impact on preventive health uptake.
Methods:
Five animated videos explaining preventive health recommendations in IBD were iteratively developed with patient-centered focus groups and interviews. A randomized controlled trial was then conducted in an internet-based IBD cohort to test the impact of video vs. text-based educational interventions. The primary outcome was receipt of the influenza vaccine. Secondary outcomes included intent-to-receive other preventive health services.
Results:
Five animated videos were developed with patient input. A total of 1056 IBD patients were then randomized to receive the video (n=511) or text-only (n=545) interventions; 55% of the video group and 57% of the text-only group had received influenza vaccination in the prior year. Immediately following the intervention, 73% reported intent-to-receive vaccination, with no difference by type of intervention. The proportion of patients who actually received influenza vaccination following the intervention also did not differ by messaging type (p=0.07). The strongest predictor of both intent-to-receive and actual receipt of influenza vaccination was prior influenza vaccination. Older age was also associated with a higher likelihood of intent-to-receive (age 36-75 relative to 18-35 years; p=0.006) as well as actual receipt (age >75 relative to age 18-35 years; p=0.05) of the influenza vaccine.
Conclusions:
The proportion of patients receiving influenza vaccine was high in both groups, but there was no difference in receipt of, or in intention-to-receive preventive health recommendations by type of messaging. Notably, a portion of patients in both groups had intended to be vaccinated but did not ultimately receive vaccination. Further evaluation of patient-education strategies is warranted to improve preventive health uptake among patients with IBD.
