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.

Automated pulmonary embolism risk classification and guideline adherence for computed tomography pulmonary angiography ordering.
The objective of this study was to measure the performance of automated, structured data-only versions of the Wells and revised Geneva risk scores in emergency department encounters during which a computed tomography pulmonary angiography was ordered. The hypothesis was that such an automated method would classify a patient's pulmonary embolism risk with high accuracy compared to manual chart review.

Qualitative study to understand ordering of CT angiography to diagnose pulmonary embolism in the emergency room setting.
The purpose of the study was to better understand, using semi-structured interviews, the decision making behind the ordering of CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) in the emergency department. The authors found that EM providers were the main drivers of CTPA ordering, and there was a marginalized role for the radiologist. Experience- and gestalt-based heuristics were the main influencers of CTPA ordering.

Utilization of head CT during injury visits to United States emergency departments: 2012-2015.
This study examined national trends in utilization of head computed tomography (CT) imaging in emergency department (ED) patients presenting with an injury-related visit. Data from the US National Hospital Ambulatory Medical Care Survey from 2012 to 2015 was used to find ED patients who had at least one head CT. Overall there was an increase (11.7-13.23%) but it was not statistically significant.

Assessing documentation of critical imaging result follow-up recommendations in emergency department discharge instructions.
The purpose of this study was to facilitate follow-up of critical test results across transitions in patient care settings, the investigators implemented an electronic discharge module that enabled care providers to include follow-up recommendations in the discharge instructions. Implementation of a discharge module was associated with increased documentation of critical imaging finding follow-up recommendations in ED discharge instructions. However, one in four patients still did not receive adequate follow-up recommendations, suggesting further opportunities for performance improvement exist.

Emergency department switching and duplicate computed tomography scans in patients with kidney stones.
The researchers measured the association between emergency department (ED) switching during a kidney stone episode and receipt of a repeat computed tomography (CT) scan. They found that 12% of patients who received a CT scan at their initial ED encounter had a revisit within 30 days of discharge. One-third of their revisits were made to a different ED than the iniital one. Duplicate CT scans were obtained at nearly 40% of all revisits. The risk of receiving a repeat CT was 12% higher if this revisit was made to a different ED. They concluded that their findings support the role of better health information exchange among providers to help reduce waste in the health-care system.

Implementation of the Canadian CT Head Rule and Its association with use of computed tomography among patients with head injury.
The researchers evaluated the association of implementation of the Canadian CT Head Rule on head computed tomography (CT) imaging in community emergency departments (EDs). They found that a multicomponent implementation of the Canadian CT Head Rule was associated with a modest reduction in CT use and an increased diagnostic yield of head CTs for adult trauma encounters in community EDs.
