The attached briefing note summaries the proposed resolution to the Observable entity and Evaluation procedure hierarchies. They were created in the early 2000s and have been maintained as separate hierarchies even though the content is overlapping in many areas. This has created confusion and inconsistency in how observation information is represented in record systems and in SNOMED CT. While some stakeholders have expressed their requirement for separate codes for ordering (evaluation procedure) and resulting (observable entity) observations, other stakeholders have expressed their requirement to include codes for ordering and resulting observations in the same hierarchy at various levels of granularity.
Previous efforts to resolve the issue and meet stakeholder needs have stalled. Details are provided in the attached briefing note.20230809 BN Evaluation procedure to Observable entity v1.0.pdf
