Differences found in package Comparison | Number of records impacted | Rationale |
|---|---|---|
| RefsetDescriptor files | 0 | NEEDS UPDATING WITH THE NEW REFSET ID FOR MEDDRA TO SNOMED |
| Delta files (ALL) | All | ALL 16 Delta files removed to match International packaging standards, as expected |
| MRCM files (x4) | All | 4x MRCM files added in to match International packaging standards, as expected |
Relationship Concrete Values files | All | Relationship Concrete Values files added in to match International packaging standards, as expected |
| ModuleDependency files | 2 | Both records updated to 2022 dates, as expected |
| Readme file | n/a | EffectiveTimes etc updated for Jan 2022, plus all Delta files removed, plus all MRCM + Relationship Concrete Values files added as expected |
| SNOMED to MedDRA Map Snapshot files | 330 | 69 records inactivated 261 records added 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....). |
| SNOMED to MedDRA Map Full files | 330 | 69 records inactivated 261 records added In TOTAL in the 2022 Snapshot record there are 4057 records:
This is as expected, as there were 3727 active records (plus 0 inactive) in the April 2021 release, plus the 261 activated + 69 inactivated in April 2022 = 4057 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 | 13184 | 6464 records inactivated (12928 record changes in total due to new refsetID) 6719 added in for 2022 (but 6464 of these are the old records with the new refsetID, in the new format)
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. |

What IS EXTREMELY CONFUSING HOWEVER, IS THAT THE OLD ORIGINAL ACTIVE RECORDS IN THE FULL FILE ARE IN THE WRONG FORMAT!!! (ie) the MapSource is in the referencedComponentId field, and the SNOMEDID is in the mapSource column!!! (eg)
THIS NEEDS FIXING SOMEHOW!!! Confirmed with Donna + Jane (on call on 22/3/22) that this should be fixed if possible, BUT if not possible in time for April then we can publish as it is, with a note in the Release Notes stating that a) the history will look strange, and so b) anyone needing to use the history should come and talk to us about how to do so...

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 Full file, plus 6464 inactivation records for those original records, plus the 6719 new format records activated + 0 inactivated in April 2022 = 19647 records expected in 2022. |
