Specimen Event Tracking (SET) profile is a project of the IHE PaLM Technical committee that was started in 2016. The purpose of this new profile of the PaLM domain is to define a series of use cases and all related events relevant to be tracked, when one or more macro operations involving a specimen occur (i.e., container preparation, collection, movement from one facility to another one, archiving, and so on).
The Specimen Event Tracking (SET) profile covers use cases and transactions related to the tracking of biological specimens in vitro collected for the purpose of diagnostic testing, during their entire lifecycle, from creation to storage inside a laboratory specimen archive or a biobank for future usage, and to final disposal. Specimen workflows can involve a ward and a laboratory in the same hospital, different laboratory facilities inside the same institution, or across different institutions. In the latter case, specimens need to be transferred by a courier service from the sending institution to the receiving institution. Another important use case to be tracked is the specimen creation for the specific purpose of becoming part of a biobank for a research institution or program. The SET profile tracks macro activities related to specimens, such as collecting, shipping, receiving, accepting... Micro operations part of a macro activity (e.g. decapping a tube) are out of scope of the profile. For most recent information on the SET please see: http://wiki.ihe.net/index.php/Pathology_and_Laboratory_Medicine_(PaLM)#Current_Activity.
Figure 1 - Some of the main events that might occur to a Specimen during its overall lifecycle, and that the SET profile aims to track. Traceability messages are collected at each step by an Informer entity and sent to a tracker entity (repository). Notice that, according to the use case, the trackers may be more than one, if the Collecting and Laboratory, if the Collecting Facility and the Laboratory have independent tracking environments.
- Keep under control the chain-of-custody of the specimen, when operation addressed by all the other profiles occur to the specimen
- Prevent specimen loss, opportunity to raise alerts if some exceptions occurs to the process (i.e., broken container, specimen collection unavailable)
- All events might be collected in a single place and use to improve the overall process
Four main use cases have been identified for the SET profile, according to the main operation that might be tracked for a specimen, in different contexts:
- Container Delivery and Specimen Collection Tracking
- Specimen Inter and Intra organization transfer
- Specimen tracking within the Laboratory
- Biobank Specimen Tracking
Each of these use cases describes a scenario where one or more macro-operations might occur to the specimen. For each operation, a correspondent event is tracked by the SET profile. An event is composed of common attributes and specific attributes. For example, all events carry the specimen identifier and the timestamp of occurrence, while only “movement related” events carry information about the departure and the arrival facilities. The SET Profile defines a total of 15 different types of events, which in turn are divided into 4 macro-categories, as shown in the following table:
