Startup K Health’s AI Chatbot Rivaled Doctors In Clinical Decisions, New Study Finds

Apr 04, 2025 - forbes.com
A study conducted by researchers at Cedars-Sinai, Tel Aviv University, and K Health found that K Health's AI chatbot matched doctors' clinical decisions in two-thirds of virtual urgent-care cases and provided superior care in the remaining one-third. The AI was particularly effective in following guidelines, though it struggled with nuanced cases. The study, published in the _Annals of Internal Medicine_, reviewed 461 patient visits and showed that the AI made fewer potentially harmful recommendations compared to physicians. K Health, founded in 2016, aims to integrate AI into healthcare to address the shortage of primary-care doctors and manage the overwhelming volume of medical data.

K Health's AI, which has been used by over 10 million people, is part of a broader effort to enhance doctor-patient interactions and improve healthcare access, quality, and cost. The company, valued at $870 million, has partnerships with major health organizations and is considering seeking FDA approval for certain AI capabilities. While AI is not expected to replace doctors, it is seen as a tool to assist physicians, particularly with straightforward cases, allowing them more time for patient interaction.

Key takeaways:

  • A study by Cedars-Sinai, Tel Aviv University, and K Health found that K Health's AI chatbot matched doctors' clinical decisions in two-thirds of cases and provided higher-quality care in the remaining one-third.
  • The AI was better at following guidelines, but struggled with nuanced cases, highlighting the importance of human intervention for complex patients with multiple comorbidities.
  • The AI made potentially harmful recommendations 2.8% of the time, compared to physicians' 4.6%, suggesting it made fewer mistakes overall.
  • K Health, valued at $870 million, aims to partner with academic institutions for potential FDA approval of certain AI capabilities, emphasizing the impact on access, quality, and cost of healthcare.
