MO HB1146

Establishes the Adult Health Care Consent Act governing health care decisions for patients unable to consent, defined as unable to appreciate their condition, make reasoned decisions, or communicate decisions in an unambiguous manner.

Creates a priority order for decision-makers: court-appointed guardians, attorneys-in-fact, spouses (unless separated), parents or adult children, adult siblings/grandparents/grandchildren, other relatives, and non-relatives with close personal relationships.

Permits health care provision without consent in emergency situations when authorized decision-makers are unavailable and delay poses substantial risk of death, serious injury, or other serious health threat.

Requires decisions by authorized persons be based on the patient's wishes when determinable, or on the patient's best interests if wishes cannot be determined.

Provides immunity from civil or criminal liability for persons making good faith health care decisions under the act and for health care providers relying on such decisions, except for negligent care.
