WHAT'S KNOWN ON THIS SUBJECT: Rapid cranial MRI is a radiation-free method to assess children with possible ventricular shunt malfunction. However, the test performance of rapid cranial MRI has never been compared with that of cranial CT, the current reference standard. WHAT THIS STUDY ADDS:The accuracy of rapid cranial MRI was not inferior to that of CT for diagnosing ventricular shunt malfunction. Rapid cranial MRI is an important radiation-sparing diagnostic alternative for children presenting emergently with possible ventricular shunt malfunction. abstract OBJECTIVES: To compare the accuracy of rapid cranial magnetic resonance imaging (MRI) with that of computed tomography (CT) for diagnosing ventricular shunt malfunction. METHODS:We performed a single-center, retrospective cohort study of children #21 years of age who underwent either rapid cranial MRI or cranial CT in the emergency department (ED) for evaluation of possible ventricular shunt malfunction. Each neuroimaging study was classified as "normal" (unchanged or decreased ventricle size) or "abnormal" (increased ventricle size). We classified a patient as having a ventricular shunt malfunction if operative revision for relief of mechanical causes of altered shunt flow was needed within 72 hours of initial ED evaluation. Our primary analysis tested noninferiority of the accuracy of rapid cranial MRI to CT for diagnosing shunt malfunction (noninferiority margin 10%). RESULTS:We included 698 ED visits for 286 unique patients, with a median age at visit of 10.0 years (interquartile range 5.9-15.5 years). Patients underwent CT in 336 (48%) or rapid cranial MRI in 362 (52%) of ED visits for evaluation of possible shunt malfunction. Patients had operative revision for ventricular shunt malfunction in 140 ED visits (20%). The accuracy of rapid cranial MRI was not inferior to that of CT scan for diagnosing ventricular shunt malfunction (81.8% MRI vs 82.4% CT; risk difference 2.0%; 95% confidence interval, -4.2% to 8.2%).CONCLUSIONS: Rapid cranial MRI was not inferior to CT for diagnosing ventricular shunt malfunction and offers the advantage of sparing a child ionizing radiation exposure.

Introduction: The receipt of remote clinical care for children via telecommunications (pediatric telemedicine) appears to improve access to and quality of care in U.S. emergency departments (EDs), but the actual prevalence and characteristics of pediatric telemedicine receipt remain unclear. We determined the prevalence and current applications of pediatric telemedicine in U.S. EDs, focusing on EDs that received telemedicine from clinicians at other facilities. Methods:We surveyed all 5,375 U.S. EDs to characterize emergency care in 2016. We then randomly surveyed 130 (39%) of the 337 EDs who reported receiving pediatric telemedicine. The second survey was administered by phone to ED directors primarily. It confirmed that the ED received pediatric telemedicine services in 2017 and asked about ED staffing and the nature, purpose, and concerns with pediatric telemedicine implementation.

Disasters have many deleterious effects and are becoming more frequent. From a health-care perspective, disasters may cause periods of stress for hospitals and health-care systems. Telemedicine is a rapidly growing technology that has been used to improve access to health-care during disasters. Telemedicine applied in disasters is referred to as disaster telemedicine. Our objective was to conduct a scoping literature review on current use of disaster telemedicine to develop recommendations addressing the most common barriers to implementation of a telemedicine system for regional disaster health response in the United States. Publications on telemedicine in disasters were collected from online databases. This included both publications in English and those translated into English. Predesigned inclusion/exclusion criteria and a PRISMA flow diagram were applied. The PRISMA flow diagram was used on the basis that it would help streamline the available literature. Literature that met the criteria was scored by 2 reviewers who rated relevance to commonly identified disaster telemedicine implementation barriers, as well as how disaster telemedicine systems were implemented. We also identified other frequently mentioned themes and briefly summarized recommendations for those topics. Literature scoring resulted in the following topics: telemedicine usage (42 publications), system design and operating models (43 publications), as well as difficulties with credentialing (5 publications), licensure (6 publications), liability (4 publications), reimbursement (5 publications), and technology (24 publications). Recommendations from each category were qualitatively summarized.

Introduction Pulmonary hypertension, associated with high mortality in pediatric patients, is traditionally screened for by trained professionals by measuring a tricuspid regurgitant jet velocity (TRJV). Our objective was to test the feasibility of novice physician sonographers (NPS) to perform echocardiograms of adequate quality to exclude pathology (defined as TRJV > 2.5 meters per second). Methods We conducted a cross-sectional study of NPS to assess TRJV by echocardiogram in an urban pediatric emergency department. NPS completed an educational course consisting of a didactic curriculum and hands-on workshop. NPS enrolled a convenience sample of patients aged 7–21 years. Our primary outcome was the proportion of echocardiograms with images of adequate quality to exclude pathology. Our secondary outcome was NPS performance on four image elements. We present descriptive statistics, binomial proportions, kappa coefficients, and logistic regression analysis. Results Eight NPS completed 80 echocardiograms. We found 82.5% (95% confidence interval [CI], 74.2–90.8) of echocardiograms had images of adequate quality to exclude pathology. Among image elements, NPS obtained a satisfactory, apical 4-chamber view in 85% (95% CI, 77.1–92.9); positioned the color box accurately 65% (95% CI, 54.5–75.5); optimized TRJV color signal 78.7% (95% CI, 69.8–87.7); and optimized continuous-wave Doppler in 55% (95% CI, 44.1–66.0) of echocardiograms. Conclusion NPS obtained images of adequate quality to exclude pathology in a majority of studies; however, optimized acquisition of specific image elements varied. This work establishes the basis for future study of NPS assessment of TRJV pathology when elevated pulmonary pressures are of clinical concern.
