The department shall establish a structured information system to gather all data necessary to carry out its duties with respect to planning, needs assessment, standard setting, evaluation, and promotion of the development of services and supports for the service recipient population, including persons who may become service recipients. The department shall design the system to avoid duplication of information gathering by other public agencies and to minimize acquisition of personally identifiable service recipient information. All public and private providers who serve persons with mental illness, serious emotional disturbance, or developmental disabilities, regardless of whether the provider is licensed under this title or other titles of the code or is unlicensed, shall provide the information required for the information system in a way consistent with this title and other laws.
