| description | This US Core FHIR Profile is meant to capture any “simple” observations that are not otherwise covered by other US Core Observation profiles. It represents any type of observation that is not classified as vital signs, laboratory, imaging, or other more specific observation types. This profile promotes interoperability and adoption through common implementation by setting minimum expectations for the Observation resource to record, search, and retrieve observations such as a clinical observation or assertion about a patient's health status or other general observations. This profile identifies which core elements, extensions, vocabularies, and value sets **SHALL** be present in the resource and constrains the way the elements are used when using this profile. It provides the floor for standards development for specific use cases. | Profile for observations that represent question and answer pairs from Social Determinants of Health (SDOH) screening instruments. |
