January 2021 Production (PUBLISHED) vs January 2022 Pre-Production Release (Version 4) traceability
Differences found in package Comparison | Number of records impacted | Rationale |
---|---|---|
RefsetDescriptor files | 0 | 0 records changed as expected |
ModuleDependency files | 2 | Both records updated to 2023 dates, as expected |
Readme file | n/a | EffectiveTimes etc updated for Jan 2023, plus all x prefixes added and PreProd naming conventions applied, as expected |
SNOMED to MedDRA Map Snapshot files | 106 | 63 records added 43 records inactivated In TOTAL in the 2022 Snapshot record there are 3988 records:
This is as expected, as there were 3727 active records (plus 0 inactive) in the April 2021 release, less the 69 inactivated in April 2022 = 3658 active records expected in 2022. This matches the Delta file from WCI exactly (BUT NOT the stats in the WCI files - emailed WCI to see if they can get the stats working....). |
MedDRA to SNOMED Map Snapshot files | 225 | 137 records added/updated, plus 85 records inactivated
VERIFIED that using the same effectiveTime for the inactivation of the previous 6464 records is fine, as although we've got 2x records with the same effectiveTime + map pair in the snapshot files, this isn't a problem as they have new UUID's (eg)
This matches the stats in the WCI files exactly (6719 new records in 2022 Prod release), but this is to be expected as technically all those records are "new" for 2022 due to new format/refsetID. This matches the Delta file from WCI exactly:
This is as expected, as there were 6464 active records (plus 0 inactive) in the April 2021 release Snapshot, plus the 255 activated + 0 inactivated in April 2022 = 6719 records expected in 2022. |
