Relationship Between Various Vocabulary Objects Value Set Group (e.g. Public Health Case Reporting) CDC PHIN VADS has 500 value sets and there is a need to group and sub-group these value sets to support various implementations Value Set Sub-Group (e.g. Hepatitis Case Reporting) Value Set Sub-Group (e.g. Tuberculosis Case Reporting) Value Set -1 (e.g. TB Risk Factors) Value Set – 2 (e.g. TB Lab Tests) ISO Current Countries Code System (3166-1) Value Set – 3 (e.g. Birth Country) Code System Concept – 1 (e.g. USA) Code System Concept – 2 (e.g. India) ISO Retired Countries Code System (3166-3) Code System Concept – 3 (e.g. U.S.S.R)
PHIN VADS Value Set Groups by HL7 Implementation Guide (Views)
PHIN VADS Value Set Group Versioning Based on HL7 IG Versions
Types of OID’s • Vocabulary OID’s • Code System OID • Value Set OID • ?? Value Set Group OID • Non-Vocabulary OID’s • Facility or Organization identifier (e.g. Kaiser Permanente in Los Angeles, California) • Application Identifier (e.g. TIMS – TB System in Georgia) • CDA Template OID (e.g. Social History Section template in CDA IG) Note: OID’s are not used for concepts for which concept code from Code system are used (e.g. SNOMED Code)
Public OID Registries • ISO OID Registry (root) • ANSI • Need to pay to register OID’s • HL7 OID Registry • All the code system OID’s need to be registered in HL7 OID registry. • CDC PHIN OID Registry • CDC still registers the code system in HL7 OID registry • CDC mainly issues OID’s that are specific for public health except for code system. • CDC obtains code system OID from HL7 OID registry.
