Please check out GitHub Upcoming Changes section to learn about what will be implemented in the upcoming August release.
TLDR:
The release will provide you with a new vocabulary for clinical trial data, more new terms, more mappings and more informations about the mappings (meta-data table). No significant impact on ETL/phenotyping processes is expected.
A longer version:
- A brand-new table capturing concept and relationship meta-data will be distributed;
- pack_content (table that stores drug pack info) will be distributed through Github;
- A new vocabulary (СDISC) will be added;
- Several source vocabularies will be refreshed (GitHub provides specific versions): ATC, LOINC, SNOMED, MedDRA, HCPCS, CPT4, CMS Place of Service, ICD10CM and EDI
- Several adjustments were made to SNOMED concepts’ domain;
- More mappings were added for MedDRA, HCPCS, CPT4, ICD10PCS, ATC and ICD condition family;
- Specifically, ATC will get more precise relationships as we changed our approach for ATC-RxNorm relationship construction to learn from US and international drug vocabularies and data sources.
