Objectives: Prospectively identifying children with significant dehydration from gastroenteritis is difficult in acute care settings. Previous work by our group has shown that bedside ultrasound (US) measurement of the inferior vena cava (IVC) and the aorta (Ao) diameter ratio is correlated with intravascular volume. This study was designed to validate the use of this method in the prospective identification of children with dehydration by investigating whether the IVC ⁄ Ao ratio correlated with dehydration in children with acute gastroenteritis. Another objective was to investigate the interrater reliability of the IVC ⁄ Ao measurements.Methods: A prospective observational study was carried out in a pediatric emergency department (PED) between November 2007 and June 2009. Children with acute gastroenteritis were enrolled as subjects. A pair of investigators obtained transverse images of the IVC and Ao using bedside US. The ratio of IVC and Ao diameters (IVC ⁄ Ao) was calculated. Subjects were asked to return after resolution of symptoms. The difference between the convalescent weight and ill weight was used to calculate the degree of dehydration. Greater than or equal to 5% difference was judged to be significant. Linear regression was performed with dehydration as the dependent variable and the IVC ⁄ Ao as the independent variable. Pearson's correlation coefficient was calculated to assess the degree of agreement between observers.Results: A total of 112 subjects were enrolled. Seventy-one subjects (63%) completed follow-up. Twentyeight subjects (39%) had significant dehydration. The linear regression model resulted in an R 2 value of 0.21 (p < 0.001) and a slope (B) of 0.11 (95% confidence interval [CI] = 0.08 to 0.14). An IVC ⁄ Ao cutoff of 0.8 produced a sensitivity of 86% and a specificity of 56% for the diagnosis of significant dehydration. Forty-eight paired measurements of IVC ⁄ Ao ratios were made. The Pearson correlation coefficient was 0.76. Conclusions:In this pilot study the ratio of IVC to Ao diameters, as measured by bedside US, was a marginally accurate measurement of acute weight loss in children with dehydration from gastroenteritis. The technique demonstrated good interrater reliability.

Objective To investigate the performance characteristics of bedside emergency department ultrasound by non-radiologist, physician sonographers in the diagnosis of ileo-colic intussusception in children. Methods This was a prospective, observational study conducted in a pediatric emergency department of an urban tertiary care children’s hospital. Pediatric emergency medicine (PEM) physicians with no previous experience in bowel ultrasound underwent a focused one-hour training session conducted by a pediatric radiologist. The session included a didactic component on sonographic appearances of ileo-colic intussusception, review of positive and negative images for intussusceptions, and a hands-on component using a live child model. Upon completion of the training a prospective convenience sample study was performed. Children were enrolled if they were to undergo a diagnostic radiology (DR) ultrasound for suspected intussusception. Bedside ultrasound (BUS) by trained PEM physicians were performed and interpreted as either positive or negative for ileo-colic intussusception. Ultrasound studies were then performed by DR and their results were used as the reference standard. Test characteristics (sensitivity, specificity, positive and negative predictive values) and likelihood ratios were calculated. Results Six PEM physicians completed the training and performed the bedside studies. Eighty two patients were enrolled. The median age was 25 months (range 3 months – 127 months). Thirteen patients (16%) were diagnosed with ileo-colic intussusception by DR. BUS had a sensitivity of 85% (95% confidence interval [CI] 54% to 97%), specificity of 97% (95% CI 89% to 99%), positive predictive value of 85% (95% CI 54% to 97%) and negative predictive value of 97% (95% CI 89% to 99%). A positive BUS had a likelihood ratio of 29 (95% CI 7.3 to 114) and a negative BUS had a likelihood ratio of 0.16 (95% CI 0.04 to 0.57). Conclusions With limited and focused training, PEM physicians can accurately diagnose ileo-colic intussusception in children using BUS.

Bedside ultrasonography can be used by pediatric emergency medicine physicians to detect skull fractures in children with acute CHI. Larger studies are needed to validate these findings. Future studies should investigate the role of this modality as an adjunct to clinical decision rules to reduce unnecessary CT scans in the evaluation of acute CHI in children.

Structured debriefings are a key component of PDM simulation education, and resulted in improved triage accuracy; the improvement was maintained five months after the educational intervention. Future curricula should emphasize assessment of CSHCN and head-injured patients.

Objective Technologies are not always successfully implemented into practise. We elicited experiences of acute care providers with the introduction of technology and identified barriers and facilitators in the implementation process. Methods A qualitative study using one-on-one interviews among a purposeful sample of 19 physicians and nurses within ten emergency departments and intensive care units was performed. Grounded theory, iterative data analysis and the constant comparative method were used to inductively generate ideas and build theories. Results Five major categories emerged: decision-making factors, the impact on practise, technology's perceived value, facilitators and barriers to implementation. Barriers included negative experiences, age, infrequent use, and access difficulties. A positive outlook, sufficient training, support staff, and user friendliness were facilitators. Conclusions This study describes strategies implicated in the successful implementation of newly adopted technology in acute care settings. Improved implementation methods and evaluation of implementation processes are necessary for successful adoption of new technology.

In this article, we analyze qualitative data from a purposeful sample of limited English proficiency (LEP) asthma health caregivers. We used ethnically concordant, semistructured, in-depth Spanish-language interviews and a follow-up focus group to explore issues related to communication during pediatric asthma encounters in medical settings. Inductive coding of Spanish transcripts by a bilingual research team was performed until thematic saturation was reached. Several key findings emerged. LEP caregivers encountered significant asthma burdens related to emotional stress, observed physical changes, and communication barriers. Language-discordant communication and the use of ad hoc interpreters were common. This finding is complex, and was influenced by perceptions of interpreter availability, delays in care, feelings of mistrust toward others, and individual emotional responses. Language-concordant education and suitable action plans were valued and desired. We discuss a revealing depiction of the LEP caregiver experience with asthma health communication and recommend areas for further inquiry.

Our simulation-based comparison suggested that JumpSTART triage outperforms both Smart and CDM. JumpSTART outperformed Smart for RED patients and CDM for BLACK patients. For YELLOW patients, JumpSTART yielded more accurate triage results than did Smart triage or CDM.

BackgroundEmotional disorders (depression and anxiety disorders) are highly prevalent mental health problems. Although evidence showing the effectiveness of disorder-specific treatments exists, high comorbidity rates among emotional disorders limit the utility of these protocols. This has led some researchers to focus their interest on transdiagnostic interventions, a treatment perspective that might be more widely effective across these disorders. Also, the current way of delivering treatments makes it difficult provide assistance to all of the population in need. The use of the Internet in the delivery of evidence-based treatments may help to disseminate treatments among the population. In this study, we aim to test the effectiveness of EmotionRegulation, a new transdiagnostic Internet-based protocol for unipolar mood disorders, five anxiety disorders (panic disorder, agoraphobia, social anxiety disorder, generalized anxiety disorder and anxiety disorder not otherwise specified), and obsessive-compulsive disorder in comparison to treatment as usual as provided in Spanish public specialized mental health care. We will also study its potential impact on basic temperament dimensions (neuroticism/behavioral inhibition and extraversion/behavioral activation). Expectations and opinions of patients about this protocol will also be studied.Methods/DesignThe study is a randomized controlled trial. 200 participants recruited in specialized care will be allocated to one of two treatment conditions: a) EmotionRegulation or b) treatment as usual. Primary outcome measures will be the BAI and the BDI-II. Secondary outcomes will include a specific measure of the principal disorder, and measures of neuroticism/behavioral inhibition and extraversion/behavioral activation. Patients will be assessed at baseline, post-treatment, and 3- and 12-month follow-ups. Intention to treat and per protocol analyses will be performed.DiscussionAlthough the effectiveness of face-to-face transdiagnostic protocols has been investigated in previous studies, the number of published transdiagnostic Internet-based programs is still quite low. To our knowledge, this is the first randomized controlled trial studying the effectiveness of a transdiagnostic Internet-based treatment for several emotional disorders in public specialized care. Combining both a transdiagnostic approach with an Internet-based therapy format may help to decrease the burden of mental disorders, reducing the difficulties associated with disorder-specific treatments and facilitating access to people in need of treatment. Strengths and limitations are discussed.Trial registrationClinicalTrials.gov NCT02345668. Registered 27 July 2015.
