Due to the challenges facing the Alameda Health System arising from changes in the public and private health industries, the Alameda County Board of Supervisors has determined that a transfer of governance of the Alameda Health System to an independent governing body, a hospital authority, is needed to improve the efficiency, effectiveness, and economy of the community health services provided at the medical center. To accomplish this, it is necessary that the board of supervisors be given authority to create a hospital authority. Because there is no general law under which this authority could be formed, the adoption of a special act and the formation of a special authority is authorized under this statute. The authority can receive appropriations from the Medi-Cal Inpatient Payment Adjustment Fund. The records of the hospital authority, whether paper records, records maintained in the management information system, or records in any other form, that relate to trade secrets or to payment rates or the determination thereof, or that relate to contract negotiations with providers of health care, shall not be subject to disclosure pursuant to the California Public Records Act. Contracts by and between the hospital authority and the state and contracts by and between the hospital authority and providers of health care, goods, or services may be let on a nonbid basis and shall be exempt from Chapter 2 (commencing with Section 10290) of Part 2 of Division 2 of the Public Contract Code.
