Efficacy and impact of a multimodal intervention on CT pulmonary angiography ordering behavior in the emergency department.
The objective of this study was to evaluate the efficacy of a multimodal intervention to reduce overutilization of computed tomography pulmonary angiography (CTPA) for suspected pulmonary embolism in the emergency department. Results indicated that guideline concordance increased significantly after intervention. The authors concluded that their success in increasing guideline concordance demonstrated the efficacy of a mixed-methods, human-centered approach to behavior change; however, given that neither of the secondary outcomes improved, the results may demonstrate potential limitations to the guidelines directing the ordering of CTPA studies.

Time to diagnostic certainty for saddle pulmonary embolism in hospitalized patients.
The purpose of this retrospective observational study was to explore the concept of the time to diagnostic certainty, defined as the interval between first patient presentation and confirmed pulmonary embolism (PE) diagnosis with computed tomography pulmonary angiogram (CT PA). Participants were randomly selected adult patients admitted to academic medical centers and associated community-based hospitals in one health system with a diagnosis of acute saddle PE. Time to diagnostic certainty ranged from 1.5 to 310 hours; the median time to treatment was 3.5 hours.

Higher imaging yield when clinical decision support is used.
Increased utilization of CT pulmonary angiography (CTPA) for the evaluation of pulmonary embolism has been associated with decreasing diagnostic yields and rising concerns about the harms of unnecessary testing. The objective of this study was to determine whether clinical decision support (CDS) use would be associated with increased imaging yields after controlling for selection bias.

The design of PE Dx, a CDS to support pulmonary embolism diagnosis in the ED.
One possible explanation for user resistance to clinical decision support (CDS) procedures may be poor CDS design. This study describes the design of PE Dx, a CDS built to aid in the diagnosis of pulmonary embolism in the emergency department using human factors methods.

Limb embolism in a 52-year-old woman.
In response to a photo quiz, the authors make the following diagnosis: arterial thrombus caused by Histoplasma capsulatum deriving from native valve endocarditis caused by the same organism. Various aspects of the case are discussed.
