Prescribing for a patient pseudonym
|
|
===================================
|
|
|
|
Purpose:
|
|
Pull a concise prescribing history for one pseudonym.
|
|
|
|
Use carefully:
|
|
- Do not commit real patient pseudonyms into shared repos.
|
|
- Keep row-level extracts out of git and shared folders unless there is a
|
|
clear information governance basis.
