As part of its conduct of investigations, the board may examine witnesses, administer oaths, and issue subpoenas, except that the board may not compel the attendance of the respondent in an investigation. A subpoena for patient record information may be issued only if the supervising member, executive director, secretary, and an attorney from the office of the attorney general determine that there is probable cause to believe that the complaint alleges a violation of this chapter and that the records sought are relevant to the alleged violation and material to the investigation. No member of the board who supervises the investigation or approves the issuance of a subpoena for patient records shall participate in further adjudication of the case. The subpoena may apply only to records that cover a reasonable period of time surrounding the alleged violation. On failure of a person to comply with a subpoena issued by the board and after reasonable notice to that person, the board may move for an order compelling the production of records or persons pursuant to the Rules of Civil Procedure.
A subpoena issued by the board may be served by a sheriff, the sheriff's deputy, or a board employee designated by the board. Service of a subpoena issued by the board may be made by delivering a copy of the subpoena to the person named in the subpoena, reading it to the person, or leaving it at the person's usual place of residence. When the person being served is a person whose practice is authorized by this chapter, service of the subpoena may be made by certified mail, return receipt requested, and the subpoena shall be deemed served on the date delivery is made or the date the person refuses to accept delivery.
A sheriff's deputy who serves a subpoena shall receive the same fees as a sheriff. Each witness who appears before the board in obedience to a subpoena shall receive the fees and mileage provided for witnesses under section 119.094 of the Revised Code.
