A patient admitted under section 5122.02 of the Revised Code who requests release in writing, or whose release is requested in writing by the patient's counsel, legal guardian, parent, spouse, or adult next of kin shall be released forthwith, except that when:
Unless the patient is released within three days from the receipt of the request by the chief clinical officer, the request shall serve as a request for an initial hearing under section 5122.141 of the Revised Code. If the court finds that the patient is a person with a mental illness subject to court order, all provisions of this chapter with respect to involuntary hospitalization apply to such person.
Judicial proceedings for hospitalization shall not be commenced with respect to a voluntary patient except pursuant to this section.
Sections 5121.30 to 5121.56 of the Revised Code apply to persons received in a hospital operated by the department of mental health and addiction services on a voluntary application.
The chief clinical officer of the hospital shall provide reasonable means and arrangements for informing patients of their rights to release as provided in this section and for assisting them in making and presenting requests for release or for a hearing under section 5122.141 of the Revised Code.
Before a patient is released from a public hospital, the chief clinical officer shall, when possible, notify the board of the patient's county of residence of the patient's pending release after the chief clinical officer has informed the patient that the board will be so notified.
