Appropriate use of cardiac stress testing with imaging: a systematic review and meta-analysis.
The authors systematically reviewed studies of appropriate use criteria (AUC), evaluated trends over time, and characterized leading indications for inappropriate testing. They found that rates of appropriate use tend to be lower for stress echocardiography compared to myocardial perfusion imaging, and updated AUC reduced unclassified stress echocardiograms. They concluded that there is no conclusive evidence that AUC improved appropriate use over time.

The association between physician empathy and variation in imaging use.
This paper's objective was to describe empathy in a cohort of emergency physicians and evaluate its association with CT utilization. The authors found that, on the four psychometric scales used, performance was not predictive of risk-adjusted CT utilization in the emergency department. They concluded that the underlying physician-based factors that mediate interphysician variation remain to be clearly identified.

The role of decision models in health care policy: a case study.
In 2009, the Centers for Medicare and Medicaid Services (CMS) underwent a National Coverage Determination on computed tomography colonography (CTC) to screen for colorectal cancer. The Cancer Intervention & Surveillance Network developed decision models to inform this decision. The purpose of this study was to investigate the role of models in this decision. It concluded that decision makers involved in the CTC decision believed in the adequacy of models to inform coverage decisions.

The impact of clinical decision rules on computed tomography use and yield for pulmonary embolism: a systematic review and meta-analysis.
The researchers performed a systematic review of impact analyses on clinical decision rules for pulmonary embolism. They found that among participants with suspected pulmonary embolism, implementation of the Wells criteria was associated with a modest increase in CT angiography yield. They concluded that there is a lack of cluster-randomized trials to confirm the efficacy of clinical decision rules for the diagnosis of pulmonary embolism.

External validation of the STONE score, a clinical prediction rule for ureteral stone: an observational multi-institutional study.
The STONE score is a clinical decision rule that classifies patients with suspected nephrolithiasis into low-, moderate-, and high-score groups, with corresponding probabilities of ureteral stone. The researchers evaluated the STONE score compared with physician gestalt. They concluded that in its present form, the STONE score lacks sufficient accuracy to allow clinicians to defer CT scan for suspected ureteral stone.

STONE PLUS: evaluation of emergency department patients with suspected renal colic, using a clinical prediction tool combined with point-of-care limited ultrasonography.
This study sought to determine whether renal point-of-care limited ultrasonography (PLUS) used in conjunction with the Sex, Timing, Origin, Nausea, Erythrocytes (STONE) clinical prediction score can aid identification of emergency department (ED) patients with uncomplicated ureteral stone or need for urologic intervention. It concluded that hydronephrosis on renal PLUS modestly improved risk stratification in low- and moderate-risk STONE score patients.

Appropriateness of cardiac stress test use among primary care physicians and cardiologists in the United States.
In this study, the researchers used nationally-representative data to examine differences in appropriate use of cardiac stress testing between cardiologists and primary care physicians (PCPs) in the US. Using permissive criteria to determine appropriateness, they found that primary care physicians are more likely to order or perform a rarely appropriate cardiac stress test than cardiologists.

Clinician perspectives on considering radiation exposure to patients when ordering imaging tests: a qualitative study.
The authors examined outpatient clinician attitudes towards considering radiation exposure when ordering CT scans and clinician reactions to displaying radiation exposure information for CT scans at clinician electronic order entry. They found that displaying clinically relevant radiation exposure information at order entry may improve clinician knowledge and inform patient-clinician discussions regarding risks and benefits of imaging.

Four-year impact of an alert notification system on closed-loop communication of critical test results.
The authors evaluated the impact of an alert notification system on policy adherence for communicating critical imaging test results to referring providers and assessed system adoption over the first 4 years after implementation. They concluded that an automated alert notification system for communicating critical imaging results was successfully adopted and was associated with increased adherence to institutional policy for communicating critical test results and with reduced workflow interruptions.
