- ACRONYMAAP-study
- hypothesisA frequently heard argument is that residents tend to attribute a serious condition to too many patients. This results in an unnecessary burden for patients having additional work-up and invasive examinations. This argument is supported by data from a previous study performed in patients with acute abdominal pain. In this study residents examined patients with a good sensitivity for urgent diagnoses (88%). However, the amount of false positive diagnoses for urgent conditions was 27%. We hypothesize that surgeons have half the false positive rates (13.5%) of surgical residents.
