Observation REST Endpoints
Description
This topic describes information for the Observation resource.
Overview
Note:
The FHIR API endpoints described below are currently pending production deployment for electronic health record (EHR) environments. Developers are welcome and encouraged to develop against the specifications in anticipation of production availability, which will be announced at a later date.The Observation resource provides measurements or assertions about a patient that are useful for establishing baselines or trends, monitoring a patient's progress, and establishing diagnoses. Most observations are name and value pair assertions, but some observations, such as blood pressure, group other observations together logically.
See the following examples of common observations:
- Laboratory results (blood sugar, hemoglobin)
- Imaging (CMS quality measure around CT radiation dose and ensuring that the dosage is As Low As Reasonably Achievable [ALARA])
- Vital signs (temperature, blood pressure)
- Personal characteristics (height, weight)
- Social history (tobacco and alcohol use, employment status)
- Survey (PRAPARE, AUDIT-C)
Pathology reports, radiology reports, and other textual reports are represented by the DiagnosticReport resource.
