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.

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.

Downstream imaging utilization after mr angiography versus CT angiography for the initial evaluation of pulmonary embolism.
This single-center, retrospective, observational study examined the use of chest CT or MR for ED patients with MR angiography (MRA) negative for PE during April 2008 to March 2013. The investigators concluded that when comparing patients initially undergoing MRA versus CTA for the evaluation of PE, there was no difference in downstream chest CT or MR use at 1 year.
