Current prescribing by VTM
|
|
=========================
|
|
|
|
Purpose:
|
|
Return patient-level prescribing records for all products under one
|
|
Virtual Therapeutic Moiety (VTM).
|
|
|
|
Data source:
|
|
REPORTING_DATASETS_ICB.SCRATCHPAD."MEDS__UnifiedPrescribingTable"
|
|
|
|
Notes:
|
|
- VTM is useful when you want all products containing the same therapeutic
|
|
moiety, regardless of brand, strength, or pack.
|
|
- The practice CTE is deliberately visible. Change the geography filter
|
|
there if the report should not be Norfolk and Suffolk.
