The Management of Children and Youth With Pediatric Mental and Behavioral Health Emergencies.

Mental and behavioral health (MBH) emergencies in children and youth continue to increasingly affect not only the emergency department (ED), but the entire spectrum of emergency medical services for children, from prehospital services to the community. Inadequate community and institutional infrastructure to care for children and youth with MBH conditions makes the ED an essential part of the health care safety net for these patients. As a result, an increasing number of children and youth are referred to the ED for evaluation of a broad spectrum of MBH emergencies, from depression and suicidality to disruptive and aggressive behavior. However, challenges in providing optimal care to these patients include lack of personnel, capacity, and infrastructure, challenges with timely access to a mental health professional, the nature of a busy ED environment, and paucity of outpatient post-ED discharge resources. These factors contribute to prolonged ED stays and boarding, which negatively affects patient care and ED operations. Strategies to improve care for MBH emergencies, including systems level coordination of care, is therefore essential. The goal of this policy statement and its companion technical report is to highlight strategies, resources, and recommendations for improving emergency care delivery for pediatric MBH.

After-hours radiology coverage in children's hospitals: a multi-center survey.

BACKGROUND: Although the provision of pediatric emergency and trauma radiology has become increasingly prevalent in North America over the last few years, many hospitals differ in their models of providing after-hours coverage. OBJECTIVE: To describe the scope of after-hours radiology services provided in children's hospitals in North America, and the means by which different radiology departments deliver this coverage. MATERIALS AND METHODS: The Society for Pediatric Radiology Emergency and Trauma Imaging Committee developed a survey that we electronically distributed to a single representative from each of the 79 hospitals represented in the Society of Chiefs of Radiology at Children's Hospitals (SCORCH). RESULTS: Completed questionnaires were submitted between Aug. 2, 2017, and Sept. 29, 2017, by 44/79 (56%) SCORCH representatives. Contemporaneous after-hours interpretation of radiographs (81%), ultrasounds (81%), body CT (79%) and neurologic CT (75%) with preliminary or final reports was common. Coverage was accomplished most commonly by a combination of evening and overnight shifts 17/44 (39%). Eleven of 44 (25%) hospitals used a model in which radiologists rotate working blocks of overnight service followed by blocks off service. Only 2/44 (5%) hospitals exclusively provided pager coverage after hours. Attending pediatric radiologists were assigned to the majority of after-hours shifts 110/175 (63%), but radiology trainees provided interpretations independently for varying periods of time at 19/44 (43%) surveyed hospitals. Incentives to work after hours included the option to work remotely, as well as additional income, time off, and academic time. CONCLUSION: The model for delivering after-hours pediatric radiology coverage varies. Most hospitals, however, provide contemporaneous interpretations of radiographs, US, body CT and neurologic CT. Most institutions use evening shifts to extend coverage later, with many providing subsequent overnight coverage. Although most shifts are staffed by attending pediatric radiologists, radiology trainees commonly interpret studies independently for varying durations of time after hours.

Prevalence of Pancreatic Steatosis at a Pediatric Tertiary Care Center.

OBJECTIVES: Pancreatic steatosis in adults has been proposed to be associated with obesity; however, data on pancreatic steatosis in children are lacking. Our study aimed to measure the prevalence of pancreatic steatosis in children and to examine its association with obesity and nonalcoholic fatty liver disease. METHODS: This is a retrospective chart review study of 232 patients 2 to 18 years old who underwent abdominal computed tomographic imaging in the emergency department or inpatient ward within a 1-year time span and from whom demographics, anthropometrics, and medical history were obtained. Our radiologist determined mean Hounsfield unit (HU) measurements for the pancreas, liver, and spleen. A difference of -20 between the pancreas and spleen (psHU) and between the liver and spleen was used to determine fatty infiltration. RESULTS: Of the 232 patients, 11.5% had a psHU less than -20. The prevalence of pancreatic steatosis was more than double among obese children (19%) than that in nonobese groups (8%). There is a significant correlation between the psHU and liver-spleen HU (r = 0.50, P < 0.001). CONCLUSIONS: Pancreatic steatosis was identified in 10% of the study population and is associated with obesity. Also, pancreatic steatosis is significantly associated with nonalcoholic fatty liver disease. This is the first study assessing the prevalence of pancreatic steatosis in children.

Effect of Public Reporting on MR Imaging Use for Low Back Pain.

PURPOSE: To determine whether magnetic resonance (MR) imaging examination rates for low back pain before conservative therapy in the Medicare and privately insured populations changed after introduction of a Centers for Medicare & Medicaid Services public reporting initiative. MATERIALS AND METHODS: Institutional review board approval was obtained, with waiver of informed consent. A retrospective study was performed by using fee-for-service claims data from Medicare and a commercial carrier (Blue Cross Blue Shield of Texas [BCBSTX]) for Texas enrollees. OP-8 was calculated, which is a publicly reported measure as of 2009 of the proportion of MR imaging examinations performed for low back pain without history of conservative therapy. For 330 463 MR imaging examinations, OP-8 rates, trends, and regional variation were analyzed for 2008-2011 within different outpatient settings-outpatient hospital department (OHD) and nonhospital outpatient department (NOD)-according to payer. Largest-volume hospitals were also evaluated within the Medicare population. RESULTS: No significant reduction was found in annual OP-8 values for Medicare or BCBSTX (Medicare OHD, 0.35 for 2008 vs 0.36 for 2009 [P = .01]; BCBSTX OHD, 0.42 for 2008 vs 0.44 for 2009 [P = .03]; Medicare NOD, 0.33 for 2008 vs 0.35 for 2009 [P < .0001]; and BCBSTX NOD, 0.43 for 2008 vs 0.42 for 2009[P = .23]). These changes were not sustained during subsequent years in the BCBSTX population, and there were no further changes in Medicare rates. Among hospitals with highest Medicare volumes, those with the highest OP-8 rates in 2008 were associated with the highest decrease in their measure. (The annual change rate was negative for all years, with 2008 as the reference [P < .0001 for 2009-2011].) Hospitals with the lowest OP-8 rates had increases in OP-8 rates, which persisted in following years (P = .006 for 2009, P = .037 for 2010, and P = .004 for 2011). Hospitals with baseline OP-8 rates in the 25th-75th percentile remained relatively steady over time. CONCLUSION: No evidence was found that public reporting (OP-8) reduced MR imaging rates for low back pain without conservative therapy in either Medicare or commercially insured populations in hospital or nonhospital settings.

Image gently campaign back to basics initiative: ten steps to help manage radiation dose in pediatric digital radiography.

OBJECTIVE: The purpose of this review is to summarize 10 steps a practice can take to manage radiation exposure in pediatric digital radiography. CONCLUSION: The Image Gently campaign raises awareness of opportunities for lowering radiation dose while maintaining diagnostic quality of images of children. The newest initiative in the campaign, Back to Basics, addresses methods for standardizing the approach to pediatric digital radiography, highlighting challenges related to the technology in imaging of patients of widely varying body sizes.

Early discharge after nonoperative management of intussusception is both safe and cost-effective.

BACKGROUND/PURPOSE: We implemented a quality improvement (QI) initiative to safely reduce post-reduction monitoring for pediatric patients with ileocolic intussusception. We hypothesized that there would be decreased length of stay (LOS) and hospital costs, with no change in intussusception recurrence rates. METHODS: A retrospective cohort study was conducted of pediatric ileocolic intussusception patients who underwent successful enema reduction at a tertiary-care pediatric hospital from January 2015 through June 2020. In September 2017, an intussusception management protocol was implemented, which allowed discharge within four hours of reduction. Pre- and post-QI outcomes were compared for index encounters and any additional encounter beginning within 24 h of discharge. An economic evaluation was performed with hospital costs inflation-adjusted to 2020 United States Dollars ($). Cost differences between groups were assessed using multivariable regression, adjusting for Medicaid and transfer status, P < 0.05 significant. RESULTS: Of 90 patients, 37(41%) were pre-QI and 53(59%) were post-QI. Patients were similar by age, sex, race, insurance status, and transfer status. Pre-QI patients had a median LOS of 23.4 h (IQR: 16.1-34.6) versus 9.3 h (IQR 7.4-14.2) for post-QI patients, P < 0.001. Mean total costs per patient in the pre-QI group were $3,231 (95% CI, $2,442-$4,020) versus $1,861 (95% CI, $1,481-$2,240) in the post-QI group. The mean absolute cost difference was $1,370 less per patient in the post-QI group (95% CI, [-$2,251]-[-$490]). Five patients had an additional encounter within 24 h of discharge [pre-QI: 1 (3%) versus post-QI: 4 (8%), p = 0.7] with four having intussusception recurrence [pre-QI: 1 (3%) versus post-QI: 3 (6%), p = 0.6]. CONCLUSIONS: Implementation of a quality improvement initiative for the treatment of pediatric intussusception reduced hospital length of stay and costs without negatively affecting post-discharge encounters or recurrence rates. Similar protocols can easily be adopted at other institutions. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective comparative treatment study.

Pediatric digital radiography education for radiologic technologists: current state.

BACKGROUND: Digital radiography (DR) is one of several new products that have changed our work processes from hard copy to digital formats. The transition from analog screen-film radiography to DR requires thorough user education because of differences in image production, processing, storage and evaluation between the forms of radiography. Without adequate education, radiologic technologists could unknowingly expose children to higher radiation doses than necessary for adequate radiograph quality. OBJECTIVE: To evaluate knowledge about image quality and dose management in pediatric DR among radiologic technologists in the U.S. MATERIALS AND METHODS: This communication describes a survey of 493 radiologic technologists who are members of the American Society of Radiologic Technologists (ASRT) and who evaluated the current state of radiological technologist education in image quality and dose management in pediatric DR. The survey included 23 survey questions regarding image acquisition issues, quality assurance, radiation exposure and education in DR of infants and children. RESULTS: Radiologic technologists express many needs in areas of training and education in pediatric DR. Suggested improvements include better tools for immediate feedback about image quality and exposure, more information about appropriate technique settings for pediatric patients, more user-friendly vendor manuals and educational materials, more reliable measures of radiation exposure to patients, and more regular and frequent follow-up by equipment vendors. CONCLUSION: There is a clear and widespread need for comprehensive and practical education in digital image technology for radiologic technologists, especially those engaged in pediatric radiography. The creation of better educational materials and training programs, and the continuation of educational opportunities will require a broad commitment from equipment manufacturers and vendors, educational institutions, pediatric radiology specialty organizations, and individual imaging specialists.

Image Gently: challenges for radiologic technologists when performing digital radiography in children.

The development of digital radiography (DR) has provided numerous benefits for pediatric imaging, including the ability to post-process images and to make images immediately available for access by care providers. However, DR presents several significant challenges for the radiologic technologists who are responsible for operating the equipment and producing high-quality images in children. This paper discusses those challenges, including lack of standardization among vendors, particularly with regard to the exposure indicator; lack of pediatric-specific educational materials and pediatric techniques; the need for manual technique instead of the use of automatic exposure control in smaller children; and complications related to field size, collimation and shielding in small children. Specific actions and design modifications that might facilitate the effective management of these challenges will be also described. The implementation of measures to promote the production of optimal images while minimizing radiation exposure requires cooperation and communication among imaging professionals, manufacturers and regulatory agencies.

Imaging of Acute Abdominal Pain in the Pediatric Population.

Acute abdominal pain is a common complaint in pediatrics. Although age and location of pain can help focus differential diagnosis, imaging plays an essential role in clinical evaluation. In this review, we discuss the optimal imaging approach to pediatric patients with acute abdominal pain and important imaging findings in the most common causes of abdominal pain in the pediatric population.

Approaching zero: Implications of a computed tomography reduction program for pediatric appendicitis evaluation.

PURPOSE: Because of awareness of iatrogenic radiation exposure, there is a national trend of diminishing computed tomography (CT) use for pediatric suspected appendicitis. The purpose of this study was to evaluate the effects of a CT reduction program for evaluation of appendicitis. METHODS: A multidisciplinary group (emergency medicine, radiology, and surgery) at a children's hospital developed a reduction program which included: ultrasound (U/S) first (2012), magnetic resonance imaging (MRI) second (2014), and standardized U/S reports (2016). Imaging modality, negative appendectomy rate, time from first image to incision, and imaging costs were evaluated over time. RESULTS: Of the 571 patients evaluated from 2012 to 2016, there was a significant decrease in CT use and increase U/S and MRI use over the study period (all p<0.01). CT use approached zero in 2016. Time from first image to incision (median 10.7h, IQR 5.6-15.5) and negative appendectomy rate (mean 3.7±0.2%) did not change. Median imaging costs ($88, IQR $52-$169) and radiology percent of total costs (range 0.8%-3.9%) increased over time (both p<0.01). CONCLUSION: Approaching zero CT use for evaluation of pediatric appendicitis is possible through a multidisciplinary protocol without impacting clinical outcomes. However, increased MRI use led to higher costs. Cost-effectiveness of replacing CT with MRI warrants further study. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: Level III.

Don't forget the dose: Improving computed tomography dosing for pediatric appendicitis.

BACKGROUND: A pediatric computed tomography (CT) radiation dose reduction program was implemented throughout our children's associated hospital system in 2010. We hypothesized that the CT dose received for evaluation of appendicitis in children would be significantly higher among the 40 referral, nonmember hospitals (NMH) than the 9 member hospitals (MH). METHODS: Preoperative CTs of pediatric (<18years) appendectomy patients between April 2012 and April 2015 were reviewed. Size specific dose estimate (SSDE), an approximation of absorbed dose incorporating patient diameter, and Effective Dose (ED) were calculated for each scan. RESULTS: 1128 (65%) of 1736 appendectomy patients underwent preoperative CT. 936 patients seen at and 102 children evaluated at NMH had dosing and patient diameter data for analysis. SSDE and ED were significantly higher with greater variance at NMH across all ages (all p<0.05, Figure). NMH's SSDE and ED also exceeded reference levels. CONCLUSION: Radiation exposure in CT scans for evaluation of pediatric appendicitis is significantly higher and more variable in NMH. A proactive approach to reduce dose, in addition to frequency, of CT scans in pediatric patients is essential. LEVEL OF EVIDENCE: Level III.

The utility of the contrast enema in neonates with suspected Hirschsprung disease.

BACKGROUND/PURPOSE: The contrast enema (CE) is commonly utilized for suspected Hirschsprung disease (HD) patients. We set out to determine the utility of the CE in the newborn for clinically suspicious HD. METHODS: All CEs performed for suspicion of HD in neonates from January 2004 to December 2013 were reviewed by two pediatric radiologists who were blinded to the original interpretations and final diagnoses. A standardized scoring sheet was utilized to document essential radiographic findings. Definitive diagnoses were determined by pathology. Descriptive statistics, likelihood ratios, and interrater agreement were determined. RESULTS: 158 CEs were reviewed. Interrater agreement was 89% with kappa (95% CI) of 0.63 (0.47-0.76). Common indications for CE were similar between non-HD and HD groups. The positive, inconclusive, and negative likelihood ratios (95% CI) were 38 (10-172), 3.2 (1.3-9.1), and 0.15 (0.06-0.47), respectively, leading to posttest probabilities for positive, inconclusive, and negative tests of 83%, 32%, and 2.5%, respectively. CONCLUSIONS: Although radiographic positive CE for HD portends a high probability of HD, inconclusive studies still represent a significant increased risk. In clinically suspicious infants for HD, those with inconclusive studies may benefit from a lower threshold to perform follow-up rectal biopsy.

The Image Gently pediatric digital radiography safety checklist: tools for improving pediatric radiography.

Transition from film-screen to digital radiography requires changes in radiographic technique and workflow processes to ensure that the minimum radiation exposure is used while maintaining diagnostic image quality. Checklists have been demonstrated to be useful tools for decreasing errors and improving safety in several areas, including commercial aviation and surgical procedures. The Image Gently campaign, through a competitive grant from the FDA, developed a checklist for technologists to use during the performance of digital radiography in pediatric patients. The checklist outlines the critical steps in digital radiography workflow, with an emphasis on steps that affect radiation exposure and image quality. The checklist and its accompanying implementation manual and practice quality improvement project are open source and downloadable at www.imagegently.org. The authors describe the process of developing and testing the checklist and offer suggestions for using the checklist to minimize radiation exposure to children during radiography.

Imaging of pediatric neck masses.

Palpable neck masses are a common indication for pediatric imaging. Such lesions may be caused by infectious, inflammatory, tumoral, traumatic, lymphovascular, immunologic, or congenital etiologies. Radiological assessment of neck masses in young children should be tailored based on patient presentation and physical examination, as well as clinical suspicion. The goal of imaging should be to help arrive at a diagnosis or limited differential in an efficient manner while minimizing radiation exposure.

Osteosclerotic metaphyseal dysplasia: a skeletal dysplasia that may mimic lead poisoning in a child with hypotonia and seizures.

We report the case of a 23-month-old male with hypotonia, developmental delay, and complex seizures. Radiographs revealed profound sclerosis of the metaphyses and epiphyses of the long and short bones in the extremities, with a unique pattern of distribution. Sclerosis also involved the anterior ribs, iliac crests, talus, and calcaneus. The skull and vertebral bodies appeared unaffected. Blood lead levels were normal. We believe that this constellation of clinical and radiographic abnormalities closely resembles osteosclerotic metaphyseal dysplasia (OMD) due to an autosomal recessive defect. Characteristic skeletal findings were instrumental in determining the diagnosis. OMD is a very rare sclerosing bone disorder, first described in 1993. The syndrome is characterized clinically by developmental delay of a progressive nature, hypotonia, elevated alkaline phosphatase, and late-onset spastic paraplegia. We encountered a young child with these neurologic symptoms who displayed sclerotic metaphyseal changes on hand radiographs obtained to determine the bone age. Lead poisoning, a known cause of metaphyseal sclerosis, was initially suspected. Careful analysis of the metaphyseal bone changes helped to distinguish this bone dysplasia from lead poisoning and other causes of metaphyseal sclerosis.

US of renal insufficiency in neonates.

Congenital and acquired renal diseases that can produce renal insufficiency during the neonatal period may be classified according to their ultrasonographic (US) characteristics: increased parenchymal echogenicity (renal parenchymal diseases, angiotensin-converting enzyme inhibitor fetopathy, cortical necrosis), cystic disease (glomerulocystic kidney disease, autosomal recessive polycystic renal disease, multicystic dysplastic kidney, cystic renal dysplasia), obstructive uropathies (ureteropelvic junction obstruction, posterior urethral valves), infections (candidal infections and bezoars), and renal agenesis. High-resolution sector and linear-array transducers allow characterization of the underlying pathologic conditions in many cases. Findings of renal parenchymal disease will vary at Doppler US and, during the acute phase, diastolic flow can be decreased, absent, or reversed. In patients with glomerulocystic kidney disease, US shows bilaterally enlarged kidneys with diffusely increased echogenicity and retention of a reniform contour, loss of corticomedullary differentiation, and cortical cysts. Obstruction of the ureteropelvic junction, the most common cause of hydronephrosis in neonates, can be seen at US as a dilated renal pelvis with dilated and communicating calices, lack of dilatation in the distal portion of the ureter, changes of renal dysplasia with increased echogenicity of the renal parenchyma, and parenchymal cysts, depending on the severity and duration of the obstruction. High-resolution US provides improved characterization of the renal parenchyma and more precise description of renal architecture.
