Genie Last Menstrual Period

This profile sets minimum expectations for an Observation resource to record, search, and fetch observations that represent the date of a patient’s last known menstrual period at a point in time with standard coding and value. It is based on the core FHIR [Observation](http://hl7.org/fhir/R4/observation.html) resource and identifies the *additional* mandatory core elements, extensions, vocabularies and value sets that **SHALL** be present in the Observation resource when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context.
