Resource Profile: Multiple Chronic Condition Care Plan Simple Observation

This profile constrains US Core Simple Observation for use in the MCC FHIR Care Plan or other FHIR Care Plans. It is using Observation resource to record, search, and fetch Observations on issues or items that are not appropriate for the other MCC FHIR Observation profiles.

Usage:

• Examples for this Resource Profile: Observation/simple-observation-example
