Background: The Choosing Wisely campaign discourages CT imaging in low-risk patients with suspected pulmonary embolism (PE) (e.g., low clinical probability and negative d-dimer). Few studies have investigated patient, provider, or operational characteristics associated with overuse of CT imaging. One possible approach to this research question is to examine variability in diagnostic yield (i.e., the percentage [...]
