OK, here I go:
I was always taught that the abbreviation for oral meds is PO. I always used that and thought it was the standard. Our computer charting software uses I believe, Medispan (I think!) for the meds, and the abbreviation used for oral meds is OR. I asked why that is, and was told that when we first started testing the sotware the question was brought up to the makers of the program, who told us that many clinics and hospitals use OR for oral meds, and "no one has ever complained". So my question is.......what does your facility, be it hospital, clinic, homecare, anything at all-use to abbreviate oral meds???? (I am just curious)!!
