PatientGPT debuts at Hartford and may push health systems to improve care

Hartford HealthCare and K Health launched PatientGPT, a generative AI chatbot embedded in MyChart that integrates with Epic and can escalate patient inquiries to providers 24/7; a KFF poll found 41 percent of users have uploaded personal medical information into AI chatbots despite 77 percent expressing privacy concerns.

Hartford HealthCare and K Health have launched PatientGPT, a generative AI chatbot embedded in the MyChart patient portal that integrates with Epic and can escalate questions to providers 24/7. The launch comes as patients increasingly use consumer AI chatbots for health questions and sometimes upload medical records despite privacy worries. K Health and Hartford leaders describe PatientGPT as trained on anonymized clinical data and designed to keep conversations visible to clinical teams. The organizations shared an internal, IRB‑reviewed study and discussed how the tool routes patients to appropriate care. Key facts: - Hartford HealthCare and K Health unveiled PatientGPT, which runs inside MyChart and integrates conversation logs into Epic so clinical teams have visibility. - A KFF tracking poll cited in the article reported that 41 percent of users said they had uploaded personal medical information into AI chatbots while 77 percent expressed privacy concerns. - K Health said PatientGPT is trained on anonymized electronic medical record data and on its historical consultations, and the company noted access to de‑identified Mayo Clinic data via a vendor relationship. - An internal, IRB‑reviewed Hartford study reported PatientGPT had a high‑risk failure rate of about 5.9 percent in testing compared with roughly 52 percent for general models in similar scenarios, described as nearly 90 percent fewer high‑risk clinical errors. - Escalation pathways described include standard emergency protocols, 24/7 virtual care (HHC 24/7 has treated nearly 50,000 patients) and routing to primary or specialty care when appropriate. Summary: Hartford HealthCare and K Health present PatientGPT as an embedded, clinically connected alternative to consumer LLMs and say they will track metrics such as access, provider experience and the types of patient questions received. The article notes ongoing questions about system bottlenecks, affordability and whether some patients seeking quick answers will continue to use general-purpose chatbots. Undetermined at this time.
