Well-child visits and immunizations among children in the U.S. declined at the pandemic’s onset and vulnerable populations have been disproportionately affected. This pilot project tested an innovative mechanism to use chatbots to engage caregivers in evidence-based preventive care for children.


We used artificial intelligence (AI)-enabled chatbots to personalize messages and facilitate appointment scheduling over a five-month period. Chatbots introduced a novel way to connect vulnerable populations to care and challenged traditional convention of provider-patient engagement.


The pilot study was conducted at a Community Health Center in Chicago, Illinois that serves roughly 10,500 children, and 82% of patients are racial and/or ethnic minorities.


We targeted outreach to 250 English and Spanish-speaking families with children 0–17 years of age for proactive outreach using chatbots promoting well-child visit completion and up-to-date immunization status; moreover, a special emphasis was placed on the 0–2 age group as the first two years represent a critical time for primary prevention of vaccine-preventable diseases.

The intervention focused on pre-visit engagement by launching an AI-enabled chatbot to deliver personalized messages and facilitate appointment scheduling via mobile devices. CHEC-UP also provided evidence-based anticipatory guidance prior to an appointment. Coaching in preparation for the visit with trusted information has the potential to educate, improve confidence and promote shared decisions between the parent and provider. Patient experience was measured via surveys deployed via the chatbot.
