210 ILCS 9/15
Prior to admission to any establishment covered by this Act, a comprehensive assessment that includes an evaluation of the prospective resident's physical, cognitive, and psychosocial condition shall be completed. At least annually, a comprehensive assessment shall be completed, and upon identification of a significant change in the resident's condition, the resident shall be reassessed. The Department may by rule specify circumstances under which more frequent assessments of skin integrity and nutritional status shall be required. The comprehensive assessment shall be completed by a physician. Based on the assessment, a written service plan shall be developed and mutually agreed upon by the provider and the resident. The service plan, which shall be reviewed annually, or more often as the resident's condition, preferences, or service needs change, shall serve as a basis for the service delivery contract between the provider and the resident. Based on the assessment, the service plan may provide for the disconnection or removal of any appliance.
