“Ubiquitin, have you (and the patient) ever benefitted from these “unnecessary” tests?”
Generally no.
The only exception is
I have gained by saving time in explaining why test wasnt indicated at a certain point it is easier to just to order it. As for the patient the only thing they may have gained is piece of mind. But most of those cases the patient doesnt even know if the test was being considered and if it is neccesary it just gets ordered pt gets wheeled of for CT scan without being told in that case Data shows ultrasound is just as effective but safer as no radiation and no contrast.
