SB 503STATE · CaliforniaIntroduced

Health care services: artificial intelligence.

Existing law requires a health facility, clinic, physician's office, or office of a group practice that uses generative artificial intelligence to generate written or verbal patient communications pertaining to patient clinical information, as defined, to ensure that those communications include both (1) a disclaimer that indicates to the patient that a communication was generated by generative artificial intelligence, as specified, and (2) clear instructions describing how a patient may contact a human health care provider, employee, or other appropriate person. Existing law exempts from this requirement a communication read and reviewed by a human licensed or certified health care provider. This bill would require developers and deployers, as defined, of an artificial intelligence system that produces a prediction, classification, recommendation, evaluation, or analysis that aids decisionmaking related to diagnosis or treatment, known as a clinical decision support system, to make reasonable efforts to identify clinical decision support systems developed for use by deployers that are known or have a reasonably foreseeable risk for biased impacts resulting from deployment of the system in health programs or activities. The bill would require developers to make a statement describing the intended uses and known or reasonably foreseeable risks associated with the use of the clinical decision support system and certain documentation available to deployers, as specified. The bill would require developers to make reasonable efforts to mitigate known or reasonably foreseeable risk for biased impacts resulting from use of the clinical decision support system in health programs or activities. The bill would require deployers to regularly monitor clinical decision support systems and take reasonable and proportionate steps to mitigate known or reasonably foreseeable risk of biased impacts. The bill would specify that a person, partnership, state or local governmental agency, or corporation may be both a developer and a deployer.
