WHO Digital Documentation of COVID-19 Certificates (DDCC)
1.0.0 - CI Build
This is the continuous build for version 1.0.0. This version is based on the current content of https://github.com/WorldHealthOrganization/ddcc and changes regularly.
| Official URL: http://smart.who.int/ddcc/StructureDefinition/DDCCObservation | Version: 1.0.0 | |||
| Draft as of 2024-04-24 | Computable Name: DDCCObservation | |||
A DDCC Observation contains the content corresponding to a row in the Test Events section of a Paper DDCC. While this is not a further profile of the International Patient Summary (IPS) Observation resouce, this is intended to map into an IPS Observation resource.
Usage:
Description of Profiles, Differentials, Snapshots and how the different presentations work.
