|

High-prescribing practice quintile template
|
||||
===========================================
|
||||
|
||||
Purpose:
|
||||
Identify practices in the highest quintile for one or more prescribing
|
||||
measures after standardising by registered population.
|
||||
|
||||
Based on the antidepressant high-prescribing analysis, but made generic:
|
||||
- Replace medicine_products with the medicine definition you need.
|
||||
- Add/remove measures in practice_counts and final_select.
|
||||
- Keep the practice and base_population CTEs visible so geography and
|
||||
denominator decisions are explicit.
