HCER Service for Patient Summary Extension
Problem Statement
The HCER supports the patient summary extension use case In this use case, after a PS is retrieved by country B, country A is informed on the healthcare encounter in country B, so country A is able to update the history of treatment events (according to its own policies).
Only the new information is sent from Country B to Country A, old clinical information is not included in the document.

List Of Features
| Use Case NR | Title | To be implemented in OpenNCP |
|---|---|---|
| UC1 | The doctor is authenticated by the portal | Basic functionality already present in OpenNCP portal and in epsos-web.
|
| UC2 | The doctor will identify the user. Its covered now from OpenNCP Portal | Functionality already present in OpenNCP portal and in epsos-web. XCPD binding. |
| UC3 | The doctor asks to create a HCER document, He also can see the patient summary document (TRCA and consent must be applied) | Assumption: Use case starts by fetching the patient summary. Then a HCER can be created as a modification of the fetched PS. Reuse the eP+eD idea for the user interface in the portal. Extension in a later sprint: If the patient does not have a PS, a HCER can be created from scratch. |
| UC4 | The system will be able to generate a new type of document HCER. The system provides the correct UI to do this |
|
| UC5 | The system will create this new type of cda document and will upload it in the relevant NCP |
The following operations are apparently not required, as in the NCP-B client connector operations and WSDLs are content-agnostic and can handle HCER documents without changes:
|
| UC6 | NCP-A must accept this document and provide info for the result |
|
| UC7 | Doctor can merge the HCER information into PatientSummary Document | Implemented as part of UC4 implementation. |
| UC8 | The doctor can query for HCER Documents of a patient | Assumption: it is the responsibility of the country A to integrate the previously submitted HCER to the patient's PS. Therefore the doctor can query PS for getting HCER information. |
What must it be implemented
- Guidelines for the new document type of HCER
- User Interface for filling the HCER document (OpenNCP Portal)
- Method for constructing a valid CDA document (OpenNCP Portal)
- Method for accepting HCER documents (NCP-A, national connector part)
- Method for merging HCER documents into Patient Summary (NCP-A). This can be decided in NCP-A method that will accept HCER document
The order of implementation
Stage 1: Implement the service for only one section of HCER: make it possible for the physician to report a new diagnosis from Country B to Country A. The diagnosis is reported using the ICD-10 code system and any additional information supported by this document section.
Stage 2: Extend the implementation with other sections.
Questions / Open Issues
- It has to be decided which type of Audit Message will be used for logging this action

CDA Body (under work)
The CDA body in the first version of the implementation only contains the Active Problems Section (1.3.6.1.4.1.19376.1.5.3.1.3.6) using which the health care professional reports a problem newly discovered in Country B. Below is an example of the body including such a section. Please pay attention to the comments, as there are further UI-related instructions in them.
