Specimen Event Tracking

From IHE Wiki
Jump to: navigation, search

Specimen Event Tracking (SET) defines all use cases and related events relevant to be tracked, when one or more operations involving a specimen occur (i.e., container preparation, collection, movement from one facility to another one, archiving, and so on).that could happen to a specimen.

Summary

The key driver around the SET is to be able to recreate the entire history of the specimen from collection to final disposition. For most recent information on the SET please see: http://wiki.ihe.net/index.php/Pathology_and_Laboratory_Medicine_(PaLM)#Current_Activity Higher level use case categories are: 1) Specimen collecting tracking: this is the starting link of the specimen tracking chain for every SET profile use case. 2) Specimen Inter-Organization transfer: these use cases cover scenarios where specimens have to be transported from an institution to another. 3) Intra-organization testing workflow specimen transfer: this use case analyzes some workflows occurring inside the same institution, where the involved facilities can be physically located in the same building, or physically separated, with an intra-organization inter-facilities transfer. 4) Intra-laboratory IVD testing specimen tracking: this use case is focused on the main tracking events happening during all In Vitro Diagnostics (IVD) testing operations performed on a specimen 5) Specimen biobank transfer: these use cases are related to the transfer of a specimen to a biobank and its future retrieval for further analysis. See also 2.7. 6) Pathology specimen tracking: this class of use cases addresses the tracking of specimens related to Anatomic Pathology testing workflow.

1) A new message type will be proposed for implementation. The main purpose for this message type is that of carrying specimen events tracking information, during all the phases of its clinical lifecycle, as: labeled containers production, collection, movement intra or inter organization/facilities, movement in an analyzer chain, biobanks, and so on. 2) The proposed structure for the new message type shall be able to carry all needed information for all the different types of events. Some of the segments/blocks will be mandatory or not, according to the different types of events that the new message is tracking. All these restricting rules could be directly addressed in IHE Specimen Event Tracking (SET) profile Volume 2 implementation. 3) For tracking purposes, some of the tracking events defined inside the SET profile require a reference to the order (i.e., Placer Order Number) that originated the request for specimens production (Transactions LAB-1 and LAB-2). In order to avoid to add into the new message structure both ORC and OBR segments only for this reason, a field inside the SPM segment has to be found, in order to fulfill these requirement. For this reason, the proposed new message structure will not consider the presence of an ORDER block section.


<Insert a simple graphic that, at a glance, visually summarizes what the profile is about. Do not use an actor/transaction diagram here. Show your graphic to someone for 5 seconds (literally) and ask them what it's about. If what they say hits the main points in your summary paragraph, you have succeeded. E.g. a graphic of a hospital, a clinic, and a lab with patient records moving between them. .>

Benefits

<If the profile can improve Cost, Safety, Quality or Efficiency then list the specific examples of that benefit (e.g. error reduction, increased throughput) and how they come about (e.g. SWF reduces patient errors due to mistyped demographics at the modality by transfering demographics electronically from the Order Filler). Consider using a bullet list for readability. Such benefits help users and vendors make the business case for the profile. If the profile does not improve any aspect of Cost, Safety, Quality or Efficiency feel free to talk about something else here.>

Details

<A few paragraphs, if appropriate, providing more details (mostly in user-speak, not tech-speak) on what the profile does and how it works.>

<If the user might be familiar with the mechanisms used by the profile, you can mention them here. E.g. Evidence Documents is based on DICOM Structured Report (SR) Templates.>

<If the user might have an appreciation for the problems addressed in the profile, you can mention them here, but keep it short. E.g. Mapping HL7 Order fields to DICOM Modality Worklist attributes can be inconsistent in the marketplace, so Scheduled Workflow provides vendors with more detailed instructions.>

Systems Affected

<List (in user terms) the types of systems they might expect to have implemented actors from this profile, e.g. RIS, PACS, HIS, CAD Workstation, etc. and for each, how it would participate.>
