Association between advanced image ordered in the emergency department on subsequent imaging for abdominal pain patients.
The purpose of this retrospective, observational study was to evaluate abdominal pain patients discharged from the ED to determine the association between advanced emergency department (ED) imaging on subsequent outpatient imaging and on revisits. The researchers utilized the electronic health records of Medicare patients who presented with a complaint of abdominal pain at a United States academic emergency department. The study found that participants who were not imaged at the ED had significantly higher adjusted odds of being imaged outside of the ED within 7, 14, and 28 days of being discharged, and had a significantly higher adjusted odds of returning to the study ED and visiting any ED within 30 days of being discharged. The study concluded that receiving abdominal imaging services in the ED was related with significantly lower imaging use after discharge.

Use of neuroimaging for children with seizure in general and pediatric emergency departments.
Investigators sought to compare rates of head computed tomography (CT) scans for pediatric seizure between general and pediatric emergency departments (EDs). Subjects were patients 21 years of age or less who presented to an ED with a chief complaint or diagnosis of seizure. They investigators found that general EDs obtained CT scans of the head more often in patients with epilepsy, without fever, and without trauma. They concluded that children with seizure were more likely to undergo CT scans of the head at general EDs compared with pediatric EDs.

Feasibility and efficacy of a decision aid for emergency department patients with suspected ureterolithiasis: protocol for an adaptive randomized controlled trial.
Both ultrasound and CT scan can be used for diagnosis of ureterolithiasis (or renal colic, the pain from an obstructing kidney stone), but the majority of patients receive a CT scan. Diagnostic pathways utilizing ultrasound have been shown to decrease radiation exposure to patients but are potentially less accurate. The investigators developed a decision aid to facilitate SDM in this scenario. The objective of this study was to determine the effects of this decision aid, as compared to usual care, on patient knowledge, radiation exposure, engagement, safety, and healthcare utilization.

Racial and ethnic differences in emergency department diagnostic imaging at US children's hospitals, 2016-2019.
Researchers evaluated racial and ethnic differences in the performance of common ED imaging studies and examined patterns across diagnoses. In this study, which evaluated visits by nonhospitalized patients younger than 18 years in 44 US children's hospital EDs, they found that non-Hispanic Black and Hispanic children were less likely to receive diagnostic imaging during ED visits compared with non-Hispanic White children. They recommended further investigation to understand and mitigate these potential disparities in health care delivery and to evaluate the effect of these differential imaging patterns on patient outcomes.

Cervical spine imaging and injuries in young children with non-motor vehicle crash-associated traumatic brain injury.
Researchers evaluated cervical magnetic resonance imaging and computed tomography practices and cervical spine injuries among a stratified random sample of young children with non-motor vehicle crash-associated traumatic brain injury (TBI). They found that abusive head trauma victims appeared to be at increased risk of cervical injuries. They recommended prospective studies to define the risk of cervical injury in children with TBI concerning for abusive head trauma and to inform development of imaging guidelines.

Trends in use of advanced imaging in pediatric emergency departments, 2009-2018.
This study looked at trends in advanced imaging use in pediatric emergency departments (ED) from 2009 to 2018. This cross-sectional study assessed 26,082,062 ED visits by children younger than 18 years from the Pediatric Health Information System administrative database. These visits were made by 9,868,406 children (mean [SD] age, 5.59 [5.15] years; 13,842,567 [53.1%] male; 9,273,181 [35.6%] non-Hispanic white) to 32 US pediatric EDs during the 10-year study period. Advanced imaging trends looked at were for computed tomography (CT), ultrasonography, and magnetic resonance imaging (MRI). Trends in ED length of stay after imaging was also examined. ED encounters increased from 6.4% in 2009 to 8.7% in 2018. There were increases for ultrasonography and MRIs, but rates decreased slightly for CT. Increased use of ultrasonography were for abdominal pain and appendectomy, and MRI for ventricular shunt procedures. The largest decreases in CT rates were for concussion, appendectomy, ventricular shunt procedures, and headaches.

Emergency ultrasound literature and adherence to standards for reporting of diagnostic accuracy criteria.
Given the wide usage of emergency point-of-care ultrasound (EUS) among emergency physicians (EPs), rigorous study surrounding its accuracy is essential. The Standards for Reporting of Diagnostic Accuracy (STARD) criteria were established to ensure robust reporting methodology for diagnostic studies. Adherence to the STARD criteria among EUS diagnostic studies has yet to be reported. In this study, the objective was to evaluate a body of EUS literature shortly after STARD publication for its baseline adherence to the STARD criteria.

Effect of initial bedside ultrasonography on emergency department skin and soft tissue infection management.
Researchers examined the utility of emergency department (ED) ultrasonography in treatment of skin and soft tissue infections. Study participants were ED patients with skin and soft tissue infections; the study also surveyed clinicians with regard to their pre-ultrasonography certainty about the presence or absence of an abscess, their planned management, post-ultrasonography findings, and actual management. The researchers found that ultrasonography rarely changed management when clinicians were certain about the presence or absence of an abscess. When clinicians were uncertain, ultrasonography changed drainage decisions in approximately one quarter of cases, of which most were appropriate.

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.

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.

Predictors of hospital admission and urological intervention in adult emergency department patients with computerized tomography confirmed ureteral stones.
In this paper, the authors describe predictors of hospital admission or urological intervention. The investigators concluded that intervention was common among admitted patients but occurred in a minority of those discharged. Predictors of intervention varied by disposition. Models incorporating computerized tomography findings were similar to those that did not incorporate such findings. The authors suggest that their data support ultrasound first or delayed computerized tomography diagnostic pathways for patients deemed clinically suitable for discharge home.
