Aim To estimate and describe trends in hospitalisations for Kawasaki disease in Australia. Methods Analysis of the National Hospital Morbidity Database for separations with a principal diagnosis of Kawasaki disease, 1993-1994 to 2017-2018. Limited to persons aged 0-19 years. Results Over the period 1993-1994 to 2017-2018, there were 6368 hospitalisations for Kawasaki disease among people aged 0-19 years; 433 same-day (6.8%) and 5935 overnight (93.2%). Among overnight separations, 15.8% were for children under the age of 1 year and 58.7% for those aged 1-4 years; 60.3% were for males. The hospitalisations rate has increased from 5.2 per 100 000 population in 1993-1994 to 12.4 per 100 000 in 2017-2018. The ratio of male to female hospitalisations was 1.5:1. Conclusions Kawasaki disease is uncommon among Australia children, but its incidence is increasing. As there are no known preventable risk factors for the disease, prompt identification and treatment remain crucial to minimising the risk of cardiovascular sequelae.

Children with glucocorticoid-treated illnesses are at risk for osteoporotic vertebral fractures, and growing awareness of this has led to increased monitoring for these fractures. However scant literature describes developmental changes in vertebral morphology that can mimic fractures. The goal of this paper is to aid in distinguishing between normal variants and fractures. We illustrate differences using lateral spine radiographs obtained annually from children recruited to the Canada-wide STeroid-Associated Osteoporosis in the Pediatric Population (STOPP) observational study, in which 400 children with glucocorticoid-treated leukemia, rheumatic disorders, and nephrotic syndrome were enrolled near glucocorticoid initiation and followed prospectively for 6 years. Normal variants mimicking fractures exist in all regions of the spine and fall into two groups. The first group comprises variants mimicking pathological vertebral height loss, including not-yet-ossified vertebral apophyses superiorly and inferiorly, which can lead to a vertebral shape easily over-interpreted as anterior wedge fracture, physiological beaking, or spondylolisthesis associated with shortened posterior vertebral height. The second group includes variants mimicking other radiologic signs of fractures: anterior vertebral artery groove resembling an anterior buckle fracture, Cupid's bow balloon disk morphology, Schmorl nodes mimicking concave endplate fractures, and parallax artifact resembling endplate interruption or biconcavity. If an unexpected vertebral body contour is detected, careful attention to its location, detailed morphology, and (if available) serial changes over time may clarify whether it is a fracture requiring change in management or simply a normal variant. Awareness of the variants described in this paper can improve accuracy in the diagnosis of pediatric vertebral fractures.

Introduction: New medical technology brings the potential of lawsuits related to the usage of that new technology. In recent years the use of point-of-care (POC) ultrasound has increased rapidly in the emergency department (ED). POC ultrasound creates potential legal risk to an emergency physician (EP) either using or not using this tool. The aim of this study was to quantify and characterize reported decisions in lawsuits related to EPs performing POC ultrasound. Methods: We conducted a retrospective review of all United States reported state and federal cases in the Westlaw database. We assessed the full text of reported cases between January 2008 and December 2012. EPs with emergency ultrasound fellowship training reviewed the full text of each case. Cases were included if an EP was named, the patient encounter was in the emergency department, the interpretation or failure to perform an ultrasound was a central issue and the application was within the American College of Emergency Physician (ACEP) ultrasound core applications. In order to assess deferred risk, cases that involved ultrasound examinations that could have been performed by an EP but were deferred to radiology were included. Results: We identified five cases. All reported decisions alleged a failure to perform an ultrasound study or a failure to perform it in a timely manner. All studies were within the scope of emergency medicine and were ACEP emergency ultrasound core applications. A majority of cases (n=4) resulted in a patient death. There were no reported cases of failure to interpret or misdiagnoses. Conclusion: In a five-year period from January 2008 through December 2012, five malpractice cases involving EPs and ultrasound examinations that are ACEP core emergency ultrasound applications were documented in the Westlaw database. All cases were related to failure to perform an ultrasound study or failure to perform a study in a timely manner and none involved failure to interpret or misdiagnosis when using of POC ultrasound.

Objectives The aim of this study was to determine the fiscal impact of implementation of a novel emergency department (ED) point-of-care (POC) ultrasound billing and reimbursement program. Methods This was a single-center retrospective study at an academic medical center. A novel POC ultrasound billing protocol was implemented using the Q-path Web-based image archival system. Patient care ultrasound examination reports were completed and signed electronically online by faculty using Q-path. A notification was automatically sent to ED coders from Q-path to bill the scans. ED coders billed the professional fees for scans on a daily basis and also notified hospital coders to bill for facility fees. A fiscal analysis was performed at the end of the year after implementing the new billing protocol, and a before-and-after comparison was conducted. Results After implementation of the new billing program, there was a 45% increase in the ED faculty participation in billing for patient care examinations (30%-75%). The number of ultrasound examinations billed increased 5.1-fold (4449 vs 857) during the post implementation period. The total units billed increased from previous year for professional services to 4157 from 649 and facility services to 3266 from 516. During the post implementation period, the facility fees revenue increased 7-fold and professional fees revenue increased 6.34-fold. After deducting the capital costs and ongoing operational costs from approximate collections, the net profits gained by our ED ultrasound program was approximately $350 000. Conclusions Within 1 year of inception, our novel POC ultrasound billing and reimbursement program generated significant revenue through ultrasound billing.

Objectives To determine the ability of emergency physicians to detect complex abnormalities on point-of-care (POC) echocardiograms. Methods Single-blinded, nonrandomized, cross-sectional study. Twenty-five different emergency medicine clinical scenarios (video clips and digital images) covering a variety of echocardiographic abnormalities were presented to a group of emergency physician sonologists. The echocardiographic abnormalities included right ventricular dysfunction, left ventricular systolic dysfunction, diastolic dysfunction, regional wall motion abnormalities, Doppler abnormalities of pericardial tamponade physiology, left ventricular hypertrophy, hypertrophic cardiomyopathy, and aortic abnormalities. All emergency physician sonologists were blinded to the study hypothesis. They reviewed echocardiography video clips and images individually, and their interpretations were compared with the criterion standard (expert echocardiographer interpretations). Results A total of 200 echocardiography studies (video clips and images) were independently reviewed by 8 emergency physician sonologists with varying POC echocardiography experiences. Emergency physicians accurately identified left ventricular systolic dysfunction 94% of the time, diastolic dysfunction (100%), and right ventricular dysfunction 80% of the time. Regional wall motion abnormalities were detected only 50% of the time. Doppler echocardiographic abnormalities of pericardial tamponade physiology were accurately identified 57% of the time. Emergency physicians who performed more than 250 POC echocardiograms were found to be more accurate in identifying complex echocardiographic abnormalities. Conclusions Our study results suggest that with increased experience, emergency physicians can accurately identify most of complex echocardiographic abnormalities.

Background Sports-related concussion remains a public health challenge due to its morbidity and mortality. One of the consequences of concussion is cognitive impairment (CI) and cognitive-related symptoms (CRS) which determine, to some extent, physical and behavioral functioning of children who sustain concussion. Despite the high prevalence of CI and CRS associated with concussion, the risk factors are not fully understood. We aimed to characterize CRS and to examine its relationship with race, ethnicity, age, insurance, and sex in a pediatric population. Methods A retrospective cohort (case-only) design was used to assess CRS prevalence and its relationship with race and sex using a pediatric hospital’s electronic medical records. A consecutive sample was used with 1429 cases between 2007 and 2014. Study characteristics were examined using chi-square and log binomial regression for hypothesis-specific testing. Results Of the 1429 cases, 872 (61.0 %) were boys and 557 (39.0 %) were girls. The racial distribution indicated 1146 (80.2 %) Whites, 170 (11.9 %) Blacks/African Americans, and 113 (7.9 %) others. The prevalence of CRS was 78.0 %. Whereas boys had sustained more concussions, girls were more likely to present with CRS; prevalence risk ratio = 1.07, 95 % CI 1.01–1.13, p = 0.02. The crude analysis indicated no racial disparities in CRS prevalence, but the multivariable analysis did, comparing White to Black/African American children; adjusted prevalence risk ratio (aPRR) = 1.77, 99 % CI 1.02–3.08, p = 0.008. Conclusions Racial disparities exist in CRS among children with sports-related concussion, and Black/African American children are more likely, relative to Whites, to suffer CRS. Due to uncertainty in causal inference, we caution the interpretation and application of these data in risk-adapted concussion prevention.

A solitary unilocular hepatic cyst (SUHC) is a rare prenatal or neonatal finding. There are few reports of the prenatal detection of SUHC, and the progression of SUHC in utero is unknown. We present a proven case of SUHC in a fetus detected on a 34-week ultrasound examination following a normal 19-week examination. The cyst was inseparable from the liver and caused some flattening of the liver edge. Prenatal detection of an SUHC inseparable from the liver and appearing in the late second or third trimester should suggest a congenital hepatic cyst.

It is reported that for individuals with spinal cord injury (SCI) the prevalence of upper limb pain is 55% to 72.7%.1-4 The pain may originate in the wrist, elbow, or shoulder. Research has been done on the factors contributing to upper limb pain, and recommendations have been given for injury prevention. One of the factors promoting upper limb pain in SCI is the repetitive task of manual wheelchair propulsion. Recommendations for injury prevention during wheelchair propulsion are to decrease repetition, to propel with a semicircular stroke pattern, to use the lightest possible wheelchair that is properly fitted, and to minimize peak forces. 5 Given that an active manual wheelchair user traverses many surfaces and obstacles, it is valuable to know the effort required to do these advanced skills. The SmartWheel (Three Rivers Holdings, LLC) has been used to analyze wheelchair propulsion on a variety of surfaces. Our objective was to use the SmartWheel to determine the forces required to do advanced wheelchair skills taken from the Wheelchair Skills Test (WST) that are often encountered in community mobility.
