Dear all,
Here I will share the vocabulary changes expected during the August 2025 release.
Traditionally, we’ll start from SNOMED. Below I attach deltas in concept and concept_relationship tables, respectively. You are welcome to explore them and share your thoughts.
Also, I would like to share some content changes performed by the SNOMED editors that are likely to affect phenotypes and ETL. They include revision of transplantation, angioplasty, and substance use/abuse hierarchies. A large number of these concepts have been deprecated by the source without replacement links. We have remapped these deprecated concepts to the active equivalents based on our clinical expertise to minimize negative impact on ETL and cohorts. Nevertheless, I encourage the Community members to pay additional attention to these concepts and their mapping changes, if these concept groups are relevant for your research.
Cheers,
Masha
