Narrative

Note: links and images are rebased to the (stated) source

Generated Narrative: CodeSystem selectivity-form

This case-sensitive code system http://hl7.org/fhir/uv/cql/CodeSystem/selectivity-form defines the following codes:

CodeDisplayDefinition
total TotalIndicates the query selectivity completely covers the criteria in the query (i.e. the query is in CNF/DNF, and all terms are sargeable).
conjunctive ConjunctiveIndicates the query selectivity represents criteria in Conjunctive Normal Form (CNF) (i.e. a conjunction of disjunctions).
disjunctive DisjunctiveIndicates the query selectivity represents criteria in Disjunctive Normal Form (DNF) (i.e. a disjunction of conjunctions).
