To address the Hospital Discharge Report Structure Challenge , we have opted for a flexible approach rather than imposing a rigid format.

The "flat structure" documented in the guide should be understood as a sort of "section library" that can be reused in both flat and nested structures. This approach allows implementers to organize the report according to local or institutional needs while maintaining a standardized content model.

In practice:

1. A few sections are required.
2. Section slices are open, meaning that implementers have the freedom to include additional "first-level" sections.
3. With the exception of a few specific cases, sub-sections are allowed, giving healthcare providers the ability to create a structure that best fits their clinical context.

By offering this level of flexibility, the implementation guide supports diverse healthcare environments while promoting consistency in content and interoperability.

Section Codes

Not all the LOINC codes used in this version align with the purpose of the sections, and in some cases, temporary 'local' codes have been assigned.

A collaboration with LOINC has been established to identify the most appropriate codes for the HDR sections.

Adopters should be aware that codes may be subject to change.
