Process for cross-domain case capture and analysis
![Page 2: IHE Supply white paper Process for cross-domain case capture and analysis](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e3f5503460f94b2f4f0/html5/thumbnails/2.jpg)
Why?
• This is a broad topic. A process helps distribute the discussion and work.
• We want to ensure other domains contribute and relate to our findings
• Collaboration across SDOs should be traced to a common, non-technical ground

Process summary
1. Describe the domain and the problem to solve2. Identify High-level directives (Business
requirements)3. Expose Use Cases4. Each use case may bring new requirements
(functional/technical)5. Trace and reconcile all requirements6. Include risk management

Business Requirements
• Should be attended in any implementation, but are not implementable in itself
![Page 5: IHE Supply white paper Process for cross-domain case capture and analysis](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e3f5503460f94b2f4f0/html5/thumbnails/5.jpg)
Use Cases
• Structure:– Summary– Preconditions– Steps– (sequence diagram)– Requirements

Use Case Summary and preconditions

Steps description
A verbal description of the scenario

Requirements
• For each case, the newly introduced requirements are listed.
• Requirements can be:– New interoperability
mechanisms– New data that must
be included in an interface

Risks
• In the writing, a new topic emerged: how to deal with risks. Example and approach:
![Page 11: IHE Supply white paper Process for cross-domain case capture and analysis](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e3f5503460f94b2f4f0/html5/thumbnails/11.jpg)
Use case scope
• There is a very broad scope, but an expected functional overlap. Examples:– Registering the use of a medication is similar to registering the
use of a device• Except for payload/...
– Ordering a medication resupply from a vendor could have the same flow as resupply of devices
• Unless a use case shows otherwise
– Informing about the medication dispense should be the same for traceable or non-traceable items
• The use cases do not need to be repeated in all detail, only the differences
![Page 12: IHE Supply white paper Process for cross-domain case capture and analysis](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e3f5503460f94b2f4f0/html5/thumbnails/12.jpg)
Approach
• Have an initial section of “detailed” use cases• New use cases can be summarized if they are
similar to existing ones.

Additional use cases
![Page 14: IHE Supply white paper Process for cross-domain case capture and analysis](https://reader030.vdocuments.mx/reader030/viewer/2022032707/56649e3f5503460f94b2f4f0/html5/thumbnails/14.jpg)
Evolution
• We have created sections for– Automated systems– Radiology– Operating Theater..– (more can be created)
• Invite other domains and groups to contribute with their use cases.– A short description is enough. – Put as many functional details as you want, leave the analysis
for a joint discussion

• Use cases– Hospital medication (several variants)
• Clinical flows• (Re)supply flows
– Ordered vs non-ordered– Consignment– Community resupply– Other care institutions– Inventory management– Traceability– ...

• Interoperabiity– HL7 v2
• Some issues
– GS1• Must update IHE template
– FHIR• Alignment needed
• AIDC– GS1 – now we have a better rationale
Profile standards

• With other IHE groups
• With HL7 and GS1
• Prepare new domain?
