California SB 503 Bill Shares Responsibilities in Clinical Artificial Intelligence Systems
The SB 503 bill introduced in California distributes the liability for algorithmic bias in clinical decision support systems to both developers and practitioners.
A new bill prepared in California mandates that clinical artificial intelligence tools used in patient care be tested against biased impacts, placing responsibility on both the developer and the healthcare provider.
Clinical Artificial Intelligence Liability
The new bill numbered SB 503, which is being addressed in California, was prepared to prove the neutrality of artificial intelligence tools used in healthcare. This regulation aims to clarify the division of duties between developers and providers using these systems.
