About this study

This study seeks to determine pregnant patients in the Philadelphia area can be recruited to a conversational AI texting platform. The trial will be considered feasible if recruitment goals are met in proportion to delivery volume at the hospital.

Read the detailed description

The investigators developed a conversational AI platform to improve periconception care (CIRCA) to engage individuals in their healthcare decision making, reduce barriers to care, and ultimately reduce widespread inequities in reproductive and maternal health.

CIRCA was developed to enable care from positive pregnancy test onward. After a positive test, patients scan a QR code to onboard via SMS to the program. A positive pregnancy test is confirmed, and an estimated gestational duration is calculated from last menstrual period, if known. If unknown, the patient is directed to schedule a visit at a nearby early pregnancy assessment center where they can receive routine testing and counseling to confirm the pregnancy and its gestational duration. They are then able to receive triage and scheduled educational content.
