1.0 17/07/2002 Proposal Patient Unique Identifier This is the string that uniquely identifies a patient within the Belgian HealthCare System. In the future, the value will refer to the national ZIS (Zorg Inschrivings nummer/Identifiant Santé) number of the patient. As long as this identifier is not available, it will contain the SIS card number (The national Registry number) to support Kmehr pilot projects. So: version 1.0 of the scheme means SIS card number, version 2.0 will mean ZIS card number. That string is placed as the value of the element ID in the element PATIENT. The scheme used is specified in the attribute 'S' of the element ID. The version of the scheme used is specified in the attribute 'SV' of the element ID. National unique identifier ID-PATIENT 1.0 <patient><id S="ID-PATIENT" SV="1.0">32031011931</id></patient> This means that the patient is the person uniquely identified by the value '32031011931' within the version '1.0' of the scheme 'ID-PATIENT' of the Belgian HealthCare Telematics Commission.
