Default DDx part- Negative findings

Hey everybody,

I have a question regarding the ddx part of the new patient note.
The instructions state to include pertinent positive as well as NEGATIVE findings to support your dx.
Could somebody enlighten me on that point?
Do they mean negative findings that make this dx likely (e.g. no murphy sign to support infectious gastroenteritis) or other findings that were not produced but would have been expected to support that diagnosis?
Thank you very much
Guy

I found this in a medical dictionary..I was a bit confused myself, but I think it means absence of a medical sign/symptom you would expect to find in certain diseases... e-g in a patient with bladder cancer you might find hematuria. so absence of hematuria would be considered a pertinent negative- If you have a patient who you suspect to have e.g pneumonia., lets say patient didnt have SOB, productive cough,fever--those would be pertinent negatives..also during PE if the lungs are clear to auscultation, you have no wheezing, rales or rhonchi, and no increased tactile fremitus, those would also be pertinent negatives for the PE part..

Does anybody have any idea whether we have time to type negative findings for each DDx?? I believe that even with fast typing this might be close to impossible in 10 minutes. Positive findings can be copy-pasted from the PE part, while negative ones need to be typed. BTW, I've never seen any negatives in CSE video PN's. They just copy-paste the positives from PE part.

no I think CSE videos mostly focus on pertinent positives for the DDx. but when they write e.g chest clear to auscultation, no rales,rhonchi or wheezing on the PE part when their differential is pneumonia, those would be pertinent negatives..

Thanks for the exaplanation. I got your point. What I am doing now, when practicing PN, I just always copy-paste the PE part relevant for particular case in all 3 of my DDx. For example, if it is abdominal pain case, I just put: Abd: nondistended, +BS, mild epigastric tenderness to palpation. No rebound or guarding. Neg Rovsing, psoas, obturator. in all three DDx (which are Gastritis, PUD, pancreatitis).
In pneumonia/pneumothorax/pleuritis case I would simply copy the same chest exam in all three DDx. I know that it looks somewhat stupid to put normal chest exam for suspected pneumothorax, but I think this is the only way not to leave the PE section in DDx blank.

Do you think this is the way to go?

ya for sure I don't know why I havent thought about using cut and paste before, I've been typing like crazy to stay within the 10 min range. It takes way too long to type everything.. do you happen to know if we can use cut and paste in the PN program for CS?
