Thanks dear 5jj. Due to some L1 interference, perhaps, I keep thinking that, 'most doctors' handwritings are illegible' and I can't help it!
Or maybe the problem is native speakers don't see this structure as their first option or so.
They've cancelled that class because now the majority of prescriptions are computer-generated. Most clinical notes are also now typed, either directly by the doctor, or dictated and typed. Personally, I think it's a complete waste of a talent that many doctors have put much time into perfecting.
