SB 2128 establishes a licensing and regulatory framework for anesthesiologist assistants (AAs) in Texas. It creates the Texas Anesthesiologist Assistant Board, which will oversee licensing, rulemaking, and disciplinary actions. The bill requires AAs to be supervised by licensed anesthesiologists and defines their scope of practice. To obtain a license, an applicant must complete an accredited graduate-level anesthesiology assistant training program, pass a certification exam, and meet continuing education requirements. The bill prohibits unlicensed individuals from practicing as anesthesiologist assistants and sets penalties for violations. It also mandates criminal background checks for applicants and establishes administrative fines for non-compliance. The Texas Medical Board will have oversight authority.
