The Privacy Consent Directive Implementation Guide applies to privacy consent directives intended to protect health information maintained in electronic health records (EHRs), personal health records (PHRs), Health Information Exchange systems (HIEs) and other forms of electronic collection and maintenance of health information.

This specification provides a mechanism to record a client’s health information privacy consent(s) and to exchange those privacy consent directives with entities that are custodians of the client's health records including Individually Identifiable Health Information (IIHI).

The scope of this project is to specify a Privacy Consent Directive in a format that may be used to sign the privacy consent as well as to allow information systems and specific rule engines to decode the assertions contained therein.

This implementation guide is a conformance profile, as described in the Refinement and Localization section of the HL7 Version 3 standards. The base standard for this implementation guide is the HL7 Clinical Document Architecture, Release 2.0.

Requirements that do not add further constraints to the base standard and that can be validated through CDA R2 XML Schema Description and conform to the CDA R2 General Header constraints do not have corresponding conformance statements in this implementation guide.
