Association of clinical guidelines and decision support with CT use in pediatric mild traumatic brain injury.
The objective of this study was to examine whether the presence of clinical guidelines and clinical decision support (CDS) for mild traumatic brain injury (mTBI) were associated with lower head computed tomography (CT) use. The investigators concluded that clinical guidelines for mTBI, and particularly CDS, were associated with lower rates of head CT use without adverse clinical outcomes.

Provider perspectives on the use of evidence-based risk stratification tools in the evaluation of pulmonary embolism: a qualitative study.
Providers often pursue imaging in patients at low risk of pulmonary embolism (PE), resulting in imaging yields <10% and false-positive imaging rates of 10% to 25%. Attempts to curb overtesting have had only modest success and no interventions have used implementation science frameworks. The objective of this study was to identify barriers and facilitators to the adoption of evidence-based diagnostic testing for PE.

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.

Determining post-test risk in a national sample of stress nuclear myocardial perfusion imaging reports: implications for natural language processing tools.
The authors investigated whether Natural Language Processing (NLP) tools could potentially help estimate myocardial perfusion imaging (MPI) risk. Subjects were VA patients who underwent stress MPI and coronary angiography 2009-11; stress test reports were randomly selected for analysis. The authors found that post-test ischemic risk was determinable but rarely reported in this sample of stress MPI reports. They conclude that this supports the potential use of NLP to help clarify risk and recommend further study of NLP in this context.

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.

Ureteral stones: implementation of a reduced-dose CT protocol in patients in the emergency department with moderate to high likelihood of calculi on the basis of STONE score.
The purpose of this paper was to determine if a reduced-dose computed tomography (CT) protocol could effectively help to identify patients in the emergency department (ED) with moderate to high likelihood of calculi who would require urologic intervention within 90 days. The authors found that a CT protocol with over 85% dose reduction can be used in patients with moderate to high likelihood of ureteral stone to safely and effectively identify patients in the ED who will require urologic intervention.

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.

Redefining overuse to include costs: a decision analysis for computed tomography in minor head injury.
This study was conducted to (1) determine the testing threshold for head computed tomography (CT) in minor head injury in the emergency department using decision analysis with and without costs included in the analysis. If only effectiveness is considered, current clinical decision rules might not provide a sufficient degree of certainty to ensure identification of all patients for whom the benefits of CT outweigh its risks.
