Hello, our group has been discussing what is the correct archetype to describe the completed action of radiotherapy contouring (the process of delineating organs and other structures on radiological images for dose delivery and avoidance purposes) and treatment planning.
Specifically, we have been interested in whether the openEHR-EHR-ACTION.procedure.v1 archetype is the correct one to record information on what structures were contoured and by whom.
Arguments in favor:
- The Purpose section of that archetype specifically mentions planning as one of the accepted uses cases. Contouring and treatment planning definitely fall into that category.
- SNOMED CT defines the following codes in its procedures valueset: 31344000 : Radiation therapy treatment planning, patient contour and localization of internal structures, 9990009 : Radiation therapy treatment planning service, 52338008 : Treatment planning for brachytherapy
Maybe the openEHR-EHR-ACTION.procedure.v1 is reserved for the procedures you do directly on the patient, with the requirement being that they are present during the procedure.
As experts, what do you guys think? Can we go with this or should we create a new ACTION-based archetype? There are not a lot of radiology and radiotherapy-based archetypes in the CKM.
Thanks in advance for your help.
