This week saw major advancements in AI agents transforming healthcare. Cedars-Sinai expanded its CS Connect chatbot to handle 42,000 telehealth visits, using AI to summarize patient symptoms and recommend treatments. Stanford Medicine demonstrated a virtual lab where AI scientists collaborated to design a COVID vaccine in days, with humans handling just 1% of the work. In research, Novartis uses protocol AI to speed up clinical trial design, potentially cutting drug development time from 8-10 years. Mayo Clinic deployed Nvidia hardware for AI-driven pathomics and drug discovery. Meanwhile, Abridge partnered with a top orthopedic hospital to automate notes for 200,000 patients annually, while Ambience raised $243 million to improve AI documentation tools. Investments in healthtech AI doubled since 2022, with AI chatbots projected to grow 20% annually.
