Required signatories under HSC section 130290(f) must sign the Data Sharing Agreement (DSA) whether or not they have an EHR. Participants should review the DSA and its Policies and Procedures, found under the Policies and Procedures section of the CDII DxF Website, to determine what health and social services information (HSSI) they are required to share. A Participant may use any system or solution to share the HSSI which they maintain, so long as they are able to comply with the requirements of the DSA and its Policies and Procedures.
