Dispensing by VTM or VMP
|
|
========================
|
|
|
|
Purpose:
|
|
Summarise dispensed items, patients, and quantity for a medicine group
|
|
using national dispensing data.
|
|
|
|
Data source:
|
|
NATIONAL.GPMED."MedicinesDispensedInPrimarycare"
|
|
|
|
Notes:
|
|
- Dispensing data is official/payment-oriented and usually lags prescribing.
|
|
- Set either VTM_SNOMED_CODE or VMP_SNOMED_CODE. Leave the other as NULL.
|
|
- ProcessingPeriodDate is a month-level period date.
