Each facility shall establish procedures whereby complaints of the patient or complaints of the staff concerning treatment of the patient can be speedily heard, with final decisions to be made by the superintendent, the regional state hospital administrator, or an advisory committee, whichever is appropriate. The board shall establish reasonable rules and regulations for the implementation of such procedures. However, the patient shall not be required to utilize these procedures in lieu of other available legal remedies.
