Extension: CQL FHIR Query Pattern Coverage

Official URL: http://hl7.org/fhir/uv/cql/StructureDefinition/cql-fhirQueryPatternCoverage Version: 3.0.0-ballot
Standards status: Trial-use Maturity Level: 1 Computable Name: CQLFHIRQueryPatternCoverage
Other Identifiers: OID:2.16.840.1.113883.4.642.40.37.42.18

Describes the extent to which the FHIR query patterns given for a data requirement (i.e. the cqf-fhirQueryPattern extensions present on the data requirement) cover the criteria of that data requirement. Because the query patterns for a data requirement are considered as a set (i.e. the union of the results of the query patterns represents the data for the data requirement), coverage is a characteristic of the data requirement as a whole, rather than of any individual query pattern. A coverage of total indicates that no further filtering of the results is required; any other value indicates that the consumer must apply the criteria of the data requirement to the results of the query patterns.
