See the full rubric →Effectiveness of theory-based WhatsApp chatbot outreach in colorectal cancer screening uptake: a randomized controlled trial.
Clinical takeawayConsider implementing WhatsApp-based chatbot outreach for adults aged 50-75 in your CRC screening program. The intervention delivers health education video and tailored behavior-change messaging based on readiness stage, improving uptake by 8-9 percentage points.
What it foundWhatsApp chatbot with video education and personalized risk-assessment increased CRC screening uptake to 36% vs 27.6% at 3 months (p=0.043) in adults aged 50-75, sustained at 6 months (45.6% vs 36.4%, p=0.045)
ContextCRC screening uptake remains suboptimal despite known mortality benefit. This trial demonstrates that structured digital outreach with education and personalized risk assessment significantly outperforms minimal reminder text, refining evidence on how to close screening gaps in community populations.

A positive stool-based test requires diagnostic colonoscopy, and stool tests should not be ordered for patients who would decline follow-up colonoscopy. Generally stop at age 75 with individualized decisions for ages 76-85 and no screening beyond 85.
