Factors Associated With Point-of-Care Ultrasound Use by Recent Pediatric Emergency Medicine Fellowship Graduates.

OBJECTIVE: The aims of this study were to describe point-of-care ultrasound (POCUS) use by recent pediatric emergency medicine (PEM) fellowship graduates and identify associations between frequency and breadth of POCUS use with variations in POCUS training and current clinical practice environment. METHODS: This was a cross-sectional online survey of recent PEM fellowship graduates. Chi-square and nonparametric tests were used to compare POCUS use among physicians with varying types of POCUS training and varying clinical practice environments. RESULTS: Eighty-two percent of 143 respondents reported using POCUS in their past 10 shifts. There was no association between the methods of POCUS education and frequency or breadth of POCUS use. Pediatric emergency medicine fellowship graduates with additional POCUS fellowship training performed more scans and used more applications than those who completed a pediatrics or medicine-pediatrics residency before PEM fellowship only [median 15 (9, 20) vs 2 (1, 5) (P < 0.01) and median 11 (6.5, 13) vs 2 (1, 3) (P < 0.01), respectively]. Participants who worked in academic emergency departments performed more ultrasounds than those who did not [3.5 (1, 8) vs 1 (0, 2), P < 0.01] and used a greater breadth of applications [3 (1, 5) vs 1 (0, 3), P < 0.01]. Physicians who billed for POCUS studies were more likely to use POCUS (odds ratio, 2.8; 95% confidence interval, 1.1-7.3) with greater frequency [5 (2.3, 10) vs 2 (0.8, 5), P < 0.01] and use a broader range of applications [3 (2,6) vs 2 (0.8, 3.3), P < 0.01]. CONCLUSION: Most respondents report recent POCUS use in practice. Point-of-care ultrasound fellowship training, working in an academic emergency department, and having the ability to bill were associated with increased POCUS use.

Pediatric Residency Point-of-Care Ultrasound Training Needs Assessment and Educational Intervention.

Background Prior studies showed that point-of-care ultrasound (POCUS) training is not commonly offered in pediatric residency. We assessed the need for a pediatric POCUS curriculum by evaluating pediatric trainees' attitudes toward the use of POCUS and identifying barriers to training. We also aimed to evaluate the impact of a POCUS educational intervention on self-efficacy and behavior. Methods We conducted a cross-sectional survey of pediatric residents in a single large freestanding children's hospital distributed via an institutional listserv and administered online. The survey included opinion-rating of statements regarding POCUS and barriers to training. We also offered a two-week POCUS course with online modules and hands-on scanning. Participating residents completed pre- and post-course knowledge assessments and follow-up surveys up to 12 months following the course to assess POCUS use and self-report confidence on POCUS indications, acquisition, interpretation, and clinical application. Results Forty-nine respondents were included in the survey representing all three pediatric levels with 16 specialty interest areas. Ninety-six percent of trainees reported that POCUS is an important skill in pediatrics. Ninety-two percent of trainees reported that residency programs should teach residents how to use POCUS. The most important perceived barriers to POCUS training were scheduling availability for POCUS rotations and lack of access to an ultrasound machine. Fourteen participants completed the pre- and post-course knowledge tests, with eight and six participants also completing the six- and 12-month follow-up surveys, respectively. Self-ratings of confidence were significantly improved post-intervention in indications (P = 0.007), image acquisition (P = 0.002), interpretation (P = 0.002), and clinical application (P = 0.004). This confidence improvement was sustained up to 6-12 months (P = 0.004-0.032). Participants also reported higher categorical POCUS use after course completion (P = 0.031). Conclusions Pediatric trainees perceive POCUS as an important skill, hold favorable opinions towards the use of POCUS, and support POCUS training within a pediatric residency. A POCUS course can improve resident POCUS knowledge, instill confidence, and motivate higher POCUS use. Further study is needed to evaluate POCUS applications in pediatric medicine to develop a standardized POCUS curriculum and establish a training guideline for pediatric residency.

Innovation at a Children's Hospital: Personal Protective Equipment Efforts During the Pandemic.

The COVID-19 pandemic has affected life for everyone, and hospitals, in particular have been hard hit. In this study, we describe our efforts to develop personal protective equipment at a children's hospital early in the pandemic. We convened an innovation working group to organize our efforts and respond to the rapidly changing situation. We describe our work in four areas: (1) plexiglass shields for the emergency department, (2) face shields for clinical providers, (3) breath shields for ophthalmology, and (4) flip-up safety glasses for nurses. The hospital's supply chain is now caught up with addressing many pandemic-related shortages. Nevertheless, through our multidisciplinary approach to reacting to the pandemic's urgent needs, we demonstrated agility to bring stakeholders together to maximize the use of scarce resources and build resiliency. We believe this method can be rapidly replicated as future needs arise.

Credentialing Pediatric Emergency Medicine Faculty in Point-of-Care Ultrasound: Expert Guidelines.

ABSTRACT: As point-of-care ultrasound (POCUS) becomes standard practice in pediatric emergency medicine (PEM), it is important to have benchmarks in place for credentialing PEM faculty in POCUS. Faculty must be systematically trained and assessed for competency in order to be credentialed in POCUS and granted privileges by an individual institution. Recommendations on credentialing PEM faculty are needed to ensure appropriate, consistent, and responsible use of this diagnostic and procedural tool. It is our intention that these guidelines will serve as a framework for credentialing faculty in PEM POCUS.

Improving antibiotic prescribing in the emergency department for uncomplicated community-acquired pneumonia.

BACKGROUND: The Pediatric Infectious Disease Society (PIDS) and Infectious Disease Society of America (IDSA) published an evidence-based guideline for the treatment of uncomplicated community-acquired pneumonia (CAP) in children, recommending aminopenicillins as the first-line therapy. Poor guideline compliance with 10%-50% of patients admitted to the hospital receiving narrow-spectrum antibiotics has been reported. A new clinical practice guideline (CPG) was implemented in our emergency department (ED) for uncomplicated CAP. The aim of this study was to examine baseline knowledge and ED provider prescribing patterns pre- and post-CPG implementation. METHODS: Prior to CPG-implementation, an anonymous case-based survey was distributed to evaluate knowledge of the current PIDS/IDSA guideline. A retrospective chart review of patients treated in the ED for CAP from January 2015 to February 2017 was performed to assess prescribing patterns for intravenous (IV) antibiotics in the ED at Children's National Health System pre- and post-CPG implementation. RESULTS: ED providers were aware of the PIDS/IDSA guideline recommendations, with 86.4% of survey responders selecting ampicillin as the initial antibiotic of choice. However, only 41.2% of patients admitted to the hospital with uncomplicated CAP pre-CPG received ampicillin (P<0.01). There was no statistically significant increase in ampicillin prescribing post-CPG (P=0.40). CONCLUSIONS: Providers in the ED are aware of the PIDS/IDSA guideline regarding the first-line therapy for uncomplicated CAP; however, this knowledge does not translate into clinical practice. Implementation of a CPG in isolation did not significantly change prescribing patterns for uncomplicated CAP.

Improving Point-of-Care Ultrasound Documentation and Billing Accuracy in a Pediatric Emergency Department.

OBJECTIVE: The performance and interpretation of point-of-care ultrasound (POCUS) should be documented appropriately in the electronic medical record (EMR) with correct billing codes assigned. We aimed to improve complete POCUS documentation from 62% to 80% and improve correct POCUS billing codes to 95% or higher through the implementation of a quality improvement initiative. METHODS: We collected POCUS documentation and billing data from the EMR. Interventions included: (1) staff education and feedback, (2) standardization of documentation and billing, and (3) changes to the EMR to support standardization. We used P charts to analyze our outcome measures between January 2017 and June 2018. RESULTS: Six hundred medical records of billed POCUS examinations were included. Complete POCUS documentation rate rose from 62% to 91%, and correct CPT code selection for billing increased from 92% to 95% after our interventions. CONCLUSIONS: The creation of a standardized documentation template incorporated into the EMR improved complete documentation compliance.

Core Content for Pediatric Emergency Medicine Ultrasound Fellowship Training: A Modified Delphi Consensus Study.

BACKGROUND: Pediatric emergency medicine (PEM) point-of-care ultrasound (POCUS) fellowships exist to provide learners with expertise in ultrasound (US) education, administration, and research oversight. Currently, there are no standardized goals or objectives for these programs, resulting in considerable variability in PEM POCUS fellowship training. METHODS: A modified Delphi survey of PEM and general emergency medicine (EM) POCUS experts in Canada and the United States was conducted to obtain consensus regarding the most important curricular components of a PEM POCUS fellowship training program. Participants were solicited from the P2 Network mailing list and from PEM and EM POCUS fellowship directors listed on the Society of Clinical Ultrasound Fellowships and the Canadian Society of POCUS-EM Fellowships websites. Curricular components considered as part of the survey included US skills, educational skills, administrative skills, and research requirements. Consensus was considered to have been reached when ≥80% of respondents agreed to either include or exclude the component in fellowship training. RESULTS: Round 1 of the survey was sent to 311 participants. A total of 118 (37.9%) completed eligibility for the survey, and 92 (78.0%) met eligibility criteria. Of those, 80 (67.8% of eligible participants) completed the first round of the survey. Round 2 of the survey was sent to those who completed part 1, and 64 (80.0%) completed that round. During Round 1, consensus was achieved for 15 of 75 US applications, seven of seven educational skills, nine of 11 administrative skills, and four of six research requirements. In Round 2 of the survey, consensus was reached on two additional US skills, but no additional administrative skills or research requirements. CONCLUSIONS: With a consensus-building process, the core content for PEM POCUS fellowship training was defined. This can help POCUS educators formulate standardized curricula to create consistent training in POCUS fellowship graduates.

Diagnostic Ultrasound Safety Review for Point-of-Care Ultrasound Practitioners.

Potential ultrasound exposure safety issues are reviewed, with guidance for prudent use of point-of-care ultrasound (POCUS). Safety assurance begins with the training of POCUS practitioners in the generation and interpretation of diagnostically valid and clinically relevant images. Sonographers themselves should minimize patient exposure in accordance with the as-low-as-reasonably-achievable principle, particularly for the safety of the eye, lung, and fetus. This practice entails the reduction of output indices or the exposure duration, consistent with the acquisition of diagnostically definitive images. Informed adoption of POCUS worldwide promises a reduction of ionizing radiation risks, enhanced cost-effectiveness, and prompt diagnoses for optimal patient care.

Systemwide Clinical Ultrasound Program Development: An Expert Consensus Model.

Clinical ultrasound (CUS) is integral to the practice of an increasing number of medical specialties. Guidelines are needed to ensure effective CUS utilization across health systems. Such guidelines should address all aspects of CUS within a hospital or health system. These include leadership, training, competency, credentialing, quality assurance and improvement, documentation, archiving, workflow, equipment, and infrastructure issues relating to communication and information technology. To meet this need, a group of CUS subject matter experts, who have been involved in institution- and/or systemwide clinical ultrasound (SWCUS) program development convened. The purpose of this paper was to create a model for SWCUS development and implementation.

Point-of-Care Ultrasound Evaluation of Severe Renal Trauma in an Adolescent.

Traumatic renal injuries are more common in pediatrics because of the relatively larger size of the kidneys in the pediatric patient. Although computerized tomography remains the criterion standard for the initial evaluation of blunt renal trauma, there is evidence that renal ultrasound may serve a role in postinjury surveillance. Here, we present a case in which point-of-care ultrasound was used to image severe blunt renal trauma in a 17-year-old adolescent boy. In this case, point-of-care ultrasound identified severely distorted renal parenchyma after a grade 5 renal laceration was identified on computerized tomography scan.

Emergency Point-of-Care Ultrasound Diagnosis of Retained Soft Tissue Foreign Bodies in the Pediatric Emergency Department.

The presence of a foreign body (FB), its depth and size, is often indeterminate by clinical examination. Conventional imaging such as a radiograph can fail to visualize soft tissue FBs. We present 2 cases where point-of-care ultrasound was used to detect previously unidentified FBs.

Pediatric emergency medicine point-of-care ultrasound: summary of the evidence.

The utility of point-of-care ultrasound is well supported by the medical literature. Consequently, pediatric emergency medicine providers have embraced this technology in everyday practice. Recently, the American Academy of Pediatrics published a policy statement endorsing the use of point-of-care ultrasound by pediatric emergency medicine providers.  To date, there is no standard guideline for the practice of point-of-care ultrasound for this specialty. This document serves as an initial step in the detailed "how to" and description of individual point-of-care ultrasound examinations.  Pediatric emergency medicine providers should refer to this paper as reference for published research, objectives for learners, and standardized reporting guidelines.

The influence of body mass index on the accuracy of ultrasound and computed tomography in diagnosing appendicitis in children.

BACKGROUND: Appendicitis is a common pediatric surgical diagnosis that is often guided by radiographic imaging such as ultrasound (US) or computed tomography (CT). Whereas US is preferred because it avoids radiation, data suggest it is less sensitive than CT in diagnosing appendicitis. Body habitus, characterized by body mass index (BMI), may affect the diagnostic value of advanced radiological imaging in children with abdominal pain. OBJECTIVE: The aim of the study was to determine the relationship between BMI and accuracy of US and CT scan for suspected appendicitis. METHODS: We conducted a prospective, observational study of children with suspected appendicitis who presented to the emergency department and underwent radiographic evaluation from June 2007 to July 2008. Patient height and weight were obtained to calculate BMI and correlating z score, zBMI. Patients were grouped into standardized categories: underweight/normal weight, overweight, and obese based on zBMI. Emergency physicians ordered imaging as guided by standard clinical management. Pediatric attending radiologists evaluated all imaging studies; final radiology reports were reviewed and coded by 2 independent reviewers. Appendicitis was defined by pathology. Statistical analysis was performed to evaluate test performance of US and CT in diagnosing appendicitis as related to BMI. RESULTS: Over the study period, 176 patients with suspected appendicitis underwent US and/or CT. Mean age was 11.8 ± 4.2 years; 42% were male. zBMI ranged from -2.78 to 2.75 (mean, 0.59); 70 children (40%) were overweight or obese; 73 (42%) had appendicitis. Ultrasound was performed on 147 (84%), and CT on 128 children (73%); 99 children (56%) had both studies. The overall sensitivity for US in diagnosing appendicitis was 38% (95% confidence interval [CI], 26%-52%) with a specificity of 97% (95% CI, 90%-99%). In the underweight/normal weight group, the sensitivity of US was 45% (95% CI, 27%-64%); in the overweight group, 35% (95% CI, 15%-61%), and in the obese group, 22% (95% CI, 4%-60%). The sensitivity and specificity of CT were 96% (95% CI, 86%-99%) and 97% (95% CI, 90%-100%) and did not vary by zBMI class. CONCLUSIONS: The sensitivity and specificity of CT for appendicitis are excellent regardless of BMI. Despite a trend of decreasing sensitivity with increasing BMI when using US, no statistically significant difference was found, likely because of type II error.

High-impact trauma causing multiple posteromedial rib fractures in a child.

Rib fractures in infants and young children are highly associated with abuse. Fractures near the costovertebral junction carry a high specificity for abuse because they result from excessive anteroposterior chest compression, which may occur when a child is gripped around the chest by an assailant. This results in excessive levering of the posterior ribs over the vertebral transverse processes, resulting in fracture near the rib head or neck. We describe a young child involved in a motor vehicle collision who sustained multiple posteromedial and lateral rib fractures in identical locations to those found in victims of abuse. In this patient, the presumed mechanism of injury was consistent with the compressive forces that cause rib fractures in abused infants and young children. This case illustrates how a high-impact traumatic event may cause rib fractures that would otherwise point strongly to abuse.

Ultrasound equipment for the pediatric emergency department: a review.

Ultrasound is gaining momentum for use in the pediatric emergency department. It is important to understand the fundamentals of ultrasound equipment as it relates to pediatric emergency medicine.

Positioning for lumbar puncture in children evaluated by bedside ultrasound.

BACKGROUND: Lumbar punctures are commonly performed in the pediatric emergency department. There is no standard, recommended, optimal position for children who are undergoing the procedure. OBJECTIVE: To determine a position for lumbar punctures where the interspinous space is maximized, as measured by bedside ultrasound. METHODS: A prospective convenience sample of children under age 12 was performed. Using a portable ultrasound device, the L3-L4 or L4-L5 interspinous space was measured with the subject in 5 different positions. The primary outcome was the interspinous distance between 2 adjacent vertebrae. The interspinous space was measured with the subject sitting with and without hip flexion. In the lateral recumbent position, the interspinous space was measured with the hips in a neutral position as well as in flexion, both with and without neck flexion. Data were analyzed by comparing pairwise differences. RESULTS: There were 28 subjects enrolled (13 girls and 15 boys) at a median age of 5 years. The sitting-flexed position provided a significantly increased interspinous space (P < .05). Flexion of the hips increased the interspinous space in both the sitting and lateral recumbent positions (P < .05). Flexion of the neck, did not significantly change the interspinous space (P = .998). CONCLUSIONS: The interspinous space of the lumbar spine was maximally increased with children in the sitting position with flexed hips; therefore we recommend this position for lumbar punctures. In the lateral recumbent position, neck flexion does not increase the interspinous space and may increase morbidity; therefore, it is recommended to hold patients at the level of the shoulders as to avoid neck flexion.
