Code Systems

OpenSHR will map codified data using the OpenMRS ReferenceTerm (or wire level codes). OpenSHR will attempt to map the ConceptSource's HL7 name to an OID (if it is in the list) or expects the ConceptSource's HL7 name to be an OID itself.
There is significant performance gains within OpenSHR when pre-loading all reference terms before processing CDAs and turning off the autoCreateConcepts flag in the OpenSHR configuration.
Table 2 provides an outline the code systems which come pre-installed with the OpenSHR CDA handler. It is important to note that this is not a fixed list and can be localized.
