Arguments

db	a database connection
clinical_table	name of the clinical table in the database
patid	name of the patid field
medcode	name of the medcode field

Note that this does not translate to Read/OXMIS codes. This function should be fast because all of the heavy lifting happens in SQLite before the data is exported to R

Examples

## Not run: 
medcode_counts <- patients_per_medcode(db)
head(medcode_counts)

## End(Not run)
