Five states have passed legislation restricting how insurers use artificial intelligence to deny medical coverage. These new laws aim to protect patients from automated denials that may lack proper human oversight. The push reflects growing concern that AI systems could create barriers to necessary care. Source

Healthcare providers worry that AI diagnostic tools may carry built-in biases that could harm patient care. While AI can reduce paperwork and help providers, experts warn these systems often reflect the biases present in their training data. This could lead to unequal care for different patient groups. Providers need better tools to identify and address these biases before widespread adoption. Source

Vektor Medical received CE mark approval for its vMap System, which uses AI to convert standard 12-lead ECGs into detailed cardiac maps. This technology could help doctors better understand heart rhythm problems and plan treatments. The system represents a significant advance in making complex cardiac mapping more accessible to healthcare providers. Source

Researchers developed a new framework called multidimensional informed generalized hypothesis testing (MIGHT) to make AI medical predictions more reliable. The system helps doctors understand when to trust AI recommendations and when to rely on clinical judgment. This could address one of the biggest barriers to AI adoption in healthcare - lack of trust in automated decisions. Source

As AI tools enter exam rooms faster than legal frameworks can adapt, questions arise about who bears responsibility when AI gets medical decisions wrong. Current malpractice law doesn't clearly address AI-related errors, leaving physicians uncertain about liability. Legal experts say new guidelines are needed to clarify responsibilities for both doctors and AI vendors. This uncertainty may slow AI adoption until clearer rules emerge. Source

The Cancer AI Alliance introduced a federated learning platform that lets cancer researchers share AI insights without sharing sensitive patient data. This approach could speed cancer research by allowing institutions to collaborate while protecting patient privacy. The platform enables AI models to learn from multiple datasets without centralizing the information. Source

These developments show healthcare AI is entering a critical phase where regulation, trust, and accountability become as important as innovation. The balance between embracing AI's benefits and managing its risks will shape how medicine evolves in the coming years.
