Okla. Stat. tit. 59, § 59-504

All citations and subpoenas, under the contemplation of this

act, shall be served in general accordance with the statutes of the

State of Oklahoma then in force applying to the service of such

documents, and all provisions of the statutes of the state then in

force, relating to citations and subpoenas, are hereby made

applicable to the citations and subpoenas herein provided for. The

secretary of the State Board of Medical Licensure and Supervision,

or the secretary's designee, during the course of an investigation,

shall have the power to issue subpoenas for the attendance of

witnesses, the inspection of premises and the production of

documents or things, including, but not limited to, pharmacy,

medical and hospital records. Such subpoenas shall carry the same

force and effect as if issued as an order from a district court of

competent jurisdiction. Patient confidentiality shall be maintained

by the Board and subpoena compliance shall not be considered a

violation of any state or federal confidentiality laws. All the

provisions of the statutes of the state, then in force, governing

the taking of testimony by depositions, are made applicable to the

taking of depositions under this act. The attendance of witnesses

shall be compelled in such hearings by subpoenas issued by the

secretary of the Board over the seal thereof, and the secretary

shall in no case refuse to issue such subpoenas upon praecipe filed

therefor accompanied with the fee of Five Dollars ($5.00) for each

subpoena issued. If any person refuse to obey such subpoena served

upon him in such manner, the fact of such refusal shall be certified

by the secretary of the Board, over the seal thereof, to the

district court of the county in which such service was had, and the

court shall proceed to hear said matter in accordance with the

statutes of the state then in force governing contempt as for

disobedience of its own process.
