Prescriptions - P.O., per os, per oris

keithlofstrom wrote on Monday, April 07, 2014:

There should be some way to select “P.O.” for “by mouth” prescription directions. That abbreviates “Per Os” (http://en.wikipedia.org/wiki/Oral_administration). NOT “Per Oris”, which might be correct Latin but not correct Doctorish or Pharmaceuticalese. We’ve had pharmacies asking what the heck “per oris” means.

Not sure where to tweak OpenEMR to fix that; hacking a few text tables had no effect on the data entry window or the printed prescription.

Do you mean this…

Admin->Lists->“Drug Routes” (From “Edit List”) (Change “Per Oris” to “P.O.” then hit save button on bottom of page)

Could have sworn that we were taught “per oris” in medical school.

The preposition “per” takes the accusative not the ablative; therefore “oris” which is singular, genitive for the third declension makes no sense. Must not have been paying attention that day, many moons ago.

Not really a biggie because everyone, on either side of the rx pad, knows the meaning of “p.o.”. Just make the change in Lists, as suggested above, and all will be right with the world.

If there is a need, could change it for future versions of OpenEMR in databse.sql

Please advise,minor issue, but why should OpenEMR not use the correct text that is used by the majority?

Scientific and therefore medical terms are Latinized… not actually
Latin… so the rules don’t usually apply.

I think it’s a case of faulty memory, on my part, because “n.p.o.”, which I wrote countless times as a pre-operative order, is “nil per os”.

Our professors in medical school had a more rigorous education in Latin than we, therefore it would be unlikely that they were grammatically incorrect.

David H. remembers his Latin better than myself. As he said, Latin sentences, including the first line of Caesar’s “Commentaries”, are tatooed to the conjunctivae of his eyelids. Will consult him about the matter and report back if there is a reply.

Hot off the press from our resident Latin scholar, David H.:

“I have no idea what they taught me in medical school, but my recollection is that ‘per’ takes the accusative case and that ‘os oris’ is a third declension neuter noun. As such, I believe that ‘per os’ is correct - or so the internet would indicate when looking up how to decline a third-declension neuter noun (I can’t confess that I really remembered). DRH”

O.K., any developer, with absolutely nothing to do; please correct the error so that our Latin teachers would not collectively roll over in their graves.

The NewCrop erx interface refers to this as “per oris”… Just sayin’

I’ll fix this today, on the my flight back from DC. If some tells me whether I should fix it to P.O. or to “Per Os”

For what it’s worth, we’ve had a few pharmacists call and ask us to clarify what was meant by Per Oris. We’ve since switched the list entry to P.O.
