a) that condition X is possibly the cause of what is bothering the patient and needs to be looked into?
OR
b) I’ve already considered/done tests/whatever about condition X and decided it isn’t that, so we need not waste further time going down that trail?
Probably I should wait for an actual doctor to respond, but it’s the first one.
Yep, it means further evaluation/testing needed to eliminate X as a possibility. Usually signifies that X is high on the list of differential diagnoses.
What does “r/o” stand for?
Rule out.
Ah! Thanks for the fast (and certain sounding) answers.
That seemed more likely to me, but I’d sometimes wonder because it could be either. Unfortunately I never happened to wonder about it while around a doctor. Good thing we have this place, eh?
Though does that mean “we need to rule out X by doing Y” or “we have ruled out X because Y”
For instance, a clinician might order a chest x-ray to “rule out pneumothorax” or a biopsy to “rule out amyloid”.
The idea is to get the radiologist or pathologist to look specifically for those things, while not missing other potential findings.
I remember a note once that said something like “probable X – r/o Y” where X was common, albeit, something that needed treating, and Y was very serious and an emergency. Turned out to be Y.
I didn’t see the note till later, and was puzzled by it, and finally go around to asking, and it meant that the symptoms could be either one, and statistically, it was probably X, but because Y, while unlikely, was so serious, it needed to be ruled out.
It was interesting how I was kinda being tossed around like your usual ER patient with a hangnail, and then suddenly, I was being handled like a Faberge egg. In 45 minutes, 4 different doctors came by to look at me. And I went from a gurney in the hallway to being informed that they had a room for me and were admitting me. Sign here.
“Rule out” is the working diagnosis, or plan. It can also be the reason for an imaging procedure or other test.
It is not stating that something has been ruled out, but that it needs to be ruled out (or confirmed).
(I realize I am repeating what others have correctly said, just wanted to further clarify)
mmm
In my case, it was a statement of a need to consider both statistics, and the seriousness of something statistically unlikely. Nothing had been been ruled out-- one or the other needed to be (or, I guess both, but then I’m not sure what the next step would have been).
In my experience much more the latter.
First FWIW “r/o” is a coder’s bane. They hate that as the diagnosis.
But in my experience it is used when a more benign diagnosis is the working diagnosis, the probable one, but the possibility of it being this or that other thing that is more concerning or needs a different treatment plan justifies the additional evaluation as diagnostic testing, to rule that out before proceeding as the more likely thing.
When you’re diagnosing and have limited information, r/o is useful for showing where you’ve reached in your clinical decision-making given the time and tools you have. Somebody presents at the ED and is hallucinating. It looks like schizophrenia or bipolar disorder, but it could be substance use, exposure to a toxin or some other physical issue. I would have characterized the psychological symptomatology as best I could but would have included rule outs in my impression to be sure the person would be assessed for possible physiological causes before a psychological diagnosis was settled on.
