Household Transmission Dynamics of Asymptomatic SARS-CoV-2-Infected Children: A Multinational, Controlled Case-Ascertained Prospective Study.

BACKGROUND: Asymptomatic SARS-CoV-2 infection in children is highly prevalent but its acute and chronic implications have been minimally described. METHODS: In this controlled case-ascertained household transmission study, we recruited asymptomatic children <18 years with SARS-CoV-2 nucleic acid testing performed at 12 tertiary care pediatric institutions in Canada and the United States. We attempted to recruit all test-positive children and 1 to 3 test-negative, site-matched controls. After 14 days' follow-up we assessed the clinical (ie, symptomatic) and combined (ie, test-positive, or symptomatic) secondary attack rates (SARs) among household contacts. Additionally, post-COVID-19 condition (PCC) was assessed in SARS-CoV-2-positive participating children after 90 days' follow-up. RESULTS: A total of 111 test-positive and 256 SARS-CoV-2 test-negative asymptomatic children were enrolled between January 2021 and April 2022. After 14 days, excluding households with co-primary cases, the clinical SAR among household contacts of SARS-CoV-2-positive and -negative index children was 10.6% (19/179; 95% CI: 6.5%-16.1%) and 2.0% (13/663; 95% CI: 1.0%-3.3%), respectively (relative risk = 5.4; 95% CI: 2.7-10.7). In households with a SARS-CoV-2-positive index child, age <5 years, being pre-symptomatic (ie, developed symptoms after test), and testing positive during Omicron and Delta circulation periods (vs earlier) were associated with increased clinical and combined SARs among household contacts. Among 77 asymptomatic SARS-CoV-2-infected children with 90-day follow-up, 6 (7.8%; 95% CI: 2.9%-16.2%) reported PCC. CONCLUSIONS: Asymptomatic SARS-CoV-2-infected children, especially those <5 years, are important contributors to household transmission, with 1 in 10 exposed household contacts developing symptomatic illness within 14 days. Asymptomatic SARS-CoV-2-infected children may develop PCC.

Characteristics and patient impact of boarding in the pediatric emergency department, 2018-2022.

OBJECTIVES: Boarding admitted patients in the emergency department is an important cause of throughput delays and safety risks in adults, though has been less studied in children. We assessed changes in boarding in a pediatric ED (PED) from 2018 to 2022 and modeled associations between boarding and select quality metrics. METHODS: We performed a retrospective analysis of PED patients admitted to non-psychiatric services, broken into four periods: pre-COVID-19 (Period I, 01/2018-02/2020), early pandemic (II, 03/2020-06/2021), COVID-19 variants (III, 07/2021-06/2022), and non-COVID respiratory viruses (IV, 07/2022-12/2022). Patients were classified as critical (intensive care units (ICU)) or acute care (non-ICU inpatient services) based on their initial bed request. We compared median boarding times with Kruskal-Wallis tests. We assessed the relationship between boarding time and hospital length-of-stay (LOS) through hazard regression models, and the association between boarding time and PED return visit, readmission, and patient safety events through adjusted logistic regressions. RESULTS: Median PED boarding time significantly increased from Period I (acute: 2.4 h; critical: 3.0 h) to Period II (acute: 3.0 h, critical: 4.0 h) to Period III (acute: 4.4 h, critical: 6.6 h) to Period IV (acute: 6.2 h; critical: 9.5 h). On survival analysis, as boarding time increased, hospital LOS increased for acute admissions and decreased for critical admissions. Increased acute care boarding time was associated with higher odds of a filed safety report. CONCLUSIONS: Since July 2021, PED boarding time increased for admitted children across acute and critical admissions. The relationship between acute care boarding and longer hospital LOS suggests a resource-inefficient, self-perpetuating cycle that demands multi-disciplinary solutions.

Utility of common bile duct measurement in the diagnosis of cholecystitis and choledocholithiasis in children.

BACKGROUND: Ultrasound is an integral part of evaluating for acute cholecystitis and choledocholithiasis in pediatric patients. Finding the common bile duct (CBD), a structure which is normally <4 mm in children, can be very challenging. OBJECTIVE: The primary objective of this study was to determine the prevalence of isolated sonographic CBD dilation in pediatric patients with acute cholecystitis and/or choledocholithiasis without laboratory abnormalities or pathologic findings on radiology based biliary ultrasound, apart from cholelithiasis. METHODS: We conducted a retrospective chart review of patients ≤21-years-old, at a single free-standing tertiary care children's hospital, who received a biliary ultrasound in the radiology department (RADUS) from September 2005 to February 2020. We identified patients who had a diagnosis of acute cholecystitis and/or choledocholithiasis on RADUS. Based on prior studies, a positive ultrasound was defined as having gallbladder wall thickening (GWT), pericholecystic fluid (PCF), or sonographic Murphy's sign (SMS). The final diagnosis was confirmed using the gold standard, cholecystectomy pathology diagnosis for patients with cholecystitis and endoscopic retrograde cholangiopancreatography (ERCP) diagnosis for patients with choledocholithiasis. Ultrasound data and contemporaneous laboratory values were collected. RESULTS: 180 patients met inclusion criteria. For the study population, 97 (53.9%) had a positive ultrasound, 127 patients (70.6%) had a dilated CBD, and 170 (94.4%) had at least one abnormal laboratory finding. Within the study population there were 76 patients (42.3%) with acute cholecystitis, 55 patients (30.5%) with choledocholithiasis, and 49 patients (27.2%) with acute cholecystitis and choledocholithiasis. Of the 127 patients with a dilated CBD, 80 (62.9%) had a normal ultrasound, apart from cholelithiasis. In this group of 80, 78 patients (97.5%) had at least one abnormal laboratory finding. Thus, for the entire study population, isolated CBD dilation without a positive ultrasound or laboratory abnormalities occurred in 2 patients (1.1%). Of note, these 2 patients had an ultrasound diagnosis of choledocholithiasis. CONCLUSION: The prevalence of isolated sonographic CBD dilation in pediatric patients with cholecystitis and/or choledocholithiasis was 1.1%. Thus, biliary ultrasound without CBD measurement is unlikely to result in missed cholecystitis and/or choledocholithiasis if the biliary ultrasound does not demonstrate GWT, PCF, SMS, or choledocholithiasis, and the patient has normal laboratory values.

Impact of Using a Precompleted Consent Form for Procedural Sedation in the Pediatric Emergency Department.

OBJECTIVES: This study aimed to compare elements discussed during the consent process for procedural sedation in the pediatric emergency department to documentation and parental recall before and after implementation of a standardized consent form. METHODS: This is a mixed-methods study combining retrospective electronic record review and cross-sectional surveys of providers and parents after consent for procedural sedation. Surveys were obtained before and after implementation of a precompleted consent form. Providers' survey responses were compared with consent documentation. Recall of consent elements discussed by linked parent-provider dyads were compared. RESULTS: Six hundred fifty-five encounters were reviewed. Pediatric emergency medicine fellows and pediatric emergency department-based pediatricians were more likely to document any benefit (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.0-2.4) or alternative (OR, 2.7; 95% CI, 1.8-3.9) compared with PEM attendings. Providers were more likely to report discussion of failure to complete the procedure (OR, 7.3; 95% CI, 2.3-23.3) and parents were more likely to recall discussion of this risk (OR, 5.3; 95% CI, 1.0-27.8) in the postintervention group. Based on provider recall, using the precompleted consent form was associated with providers discussing at least 2 of the 3 benefits (84.0% vs 97.2%, P < 0.01), 5 of the 5 risks (31% vs 67.7%, P < 0.01), and improved parental recall of risks (5.7% vs 22.9%, P = 0.03). More providers reported taking less than 1 minute to complete the form in the postimplementation group (12.0% vs 43.7%, P < 0.01). CONCLUSIONS: Implementing a precompleted consent form for procedural sedation was associated with providers reporting decreased time spent completing the consent form and better alignment of key consent elements between reported provider discussion and parental recall.

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.

Identifying pediatric patients with multisystem inflammatory syndrome in children presenting to a pediatric emergency department.

OBJECTIVE: To compare clinical and laboratory features of children with Multisystem Inflammatory Syndrome in Children (MIS-C) to those evaluated for MIS-C in the Emergency Department (ED). METHODS: We conducted a retrospective review of the medical record of encounters with testing for inflammatory markers in an urban, tertiary care Pediatric ED from March 1, 2020 to July 31, 2020. We abstracted demographic information, laboratory values, selected medications and diagnoses. We reviewed the record for clinical presentation for the subset of patients admitted to the hospital for suspected MIS-C. We then used receiver operating curves and logistic regression to evaluate the utility of candidate laboratory values to predict MIS-C status. RESULTS: We identified 32 patients with confirmed MIS-C and 15 admitted and evaluated for MIS-C but without confirmation of SARS CoV-2 infection. We compared these patients to 267 encounters with screening laboratories for MIS-C. Confirmed MIS-C patients had an older median age, higher median fever on presentation and were predominantly of Hispanic and non-Hispanic Black race/ethnicity. All children with MIS-C had a C-reactive protein (CRP) >4.5 mg/dL, were more likely to have Brain Natriuretic Peptide >400 pg/mL (OR 10.50, 95%CI 4.40-25.04), D-Dimer >3 µg/mL (7.51, [3.18-17.73]), and absolute lymphocyte count (ALC) <1.5 K/mcL (21.42, [7.19-63.76]). We found CRP >4.5 mg/dL and ALC <1.5 K/mcL to be 86% sensitive and 91% specific to identify MIS-C among patients screened in our population. CONCLUSIONS: We identified that elevated CRP and lymphopenia was 86% sensitive and 91% specific for identification of children with MIS-C.

Racial and Ethnic Differences in Prescription Filling After Discharge From an Urban Pediatric Emergency Department.

OBJECTIVE: The aim of this study was to measure racial/ethnic differences in prescription filling among children prescribed with outpatient antibiotics from the emergency department (ED). METHODS: This study is a retrospective cohort study of ED visits among children (0-21 years) from January 1 to March 31, 2018, during which oral antibiotics were prescribed. We measured the proportion of filled prescriptions in aggregate and by patient race/ethnicity. We performed multivariable logistic regression to identify patient and visit-level factors associated with prescription filling. Secondarily, we measured differences in ED revisits by prescription filling. RESULTS: A total of 2881 participants were enrolled. A total of 66.3% (95% confidence interval, 64.5-68.0) of prescriptions were filled. Prescription filling varied by race/ethnicity; these are as follows: 77.3% non-Hispanic (NH) white, 73.5% NH black, 51.5% Hispanic, and 51.3% others (P < 0.0001). After adjustment for patient and visit-level characteristics, Hispanic children (adjusted odds ratio [aOR], 0.5 [0.3-0.9]) and children of other racial/ethnic groups (aOR, 0.5 [0.3-0.8]) had lower odds of prescription filling in comparison to NH white children. Interpreter use (aOR, 0.5 [0.4-0.6]) and uninsured status (aOR, 0.4 [0.3-0.5]) were additional independent risk factors associated with lower odds of prescription filling. There were no differences in the 72-hour revisit rates between those who filled their prescriptions and those who did not. CONCLUSIONS: A third of antibiotic prescriptions for bacterial infections in the ED are unfilled. Hispanic children and children of other racial/ethnic groups have lower rates of prescription filling compared with NH white children. Interpreter use and uninsured status also have lower rates of prescription filling. Barriers to prescription filling should be explored further to help reduce racial and ethnic disparities in the provision of health care.

Patient and Visit Characteristics of Pediatric Patients With High-frequency Low-acuity Emergency Department Visits.

INTRODUCTION: Pediatric patients account for a disproportionate number of low-acuity emergency department (ED) visits. The aim of this study is to describe pediatric patient and visit characteristics for high-frequency users for low-acuity visits. METHODS: This was a retrospective cohort study of children presenting to a tertiary care pediatric ED and an affiliated community ED, over a 2-year period, with at least 10 low-acuity visits. Twenty patients with the highest number of visits were classified as "superusers." We analyzed patient data from the larger sample of high-frequency users and visit specific data from superuser visits. IBM SPSS Statistics 25 (SPSS Inc., Chicago, IL) was used to perform descriptive statistics and to summarize demographic and visit specific variables. RESULTS: We identified 181 high-frequency users with a mean number of visits of 14.3 ± 4.3 and a subpopulation of 20 superusers accounting for 434 visits. The majority of high-frequency users (89%) identified as African American and had public insurance (96.1%). Many patients received primary care affiliated with the home institution. In the first year of the study, 50.3% of high-frequency users were infants younger than 1 year at the index visit and 47.4% of superusers were infants at the index visit.Superuser visits were evenly distributed among seasons and the majority of visits occurred during the weekdays (70.7%). The majority of visits were for medical complaints (86.6%) and almost half (47.6%) resulted in some testing (24.9%) or treatment (30.6%); however, only 1.4% resulted in hospital admission. CONCLUSIONS: In our sample, most high-frequency low-acuity ED patients were infants, African American and have public insurance. Many are seen during clinic hours and are paneled at affiliated clinics. Among superusers, the majority of the visits did not require any testing, intervention, or treatment.

Characteristics and Clinical Outcomes of Children and Adolescents Aged <18 Years Hospitalized with COVID-19 - Six Hospitals, United States, July-August 2021.

During June 2021, the highly transmissible† B.1.617.2 (Delta) variant of SARS-CoV-2, the virus that causes COVID-19, became the predominant circulating strain in the United States. U.S. pediatric COVID-19-related hospitalizations increased during July-August 2021 following emergence of the Delta variant and peaked in September 2021.§ As of May 12, 2021, CDC recommended COVID-19 vaccinations for persons aged ≥12 years,¶ and on November 2, 2021, COVID-19 vaccinations were recommended for persons aged 5-11 years.** To date, clinical signs and symptoms, illness course, and factors contributing to hospitalizations during the period of Delta predominance have not been well described in pediatric patients. CDC partnered with six children's hospitals to review medical record data for patients aged <18 years with COVID-19-related hospitalizations during July-August 2021.†† Among 915 patients identified, 713 (77.9%) were hospitalized for COVID-19 (acute COVID-19 as the primary or contributing reason for hospitalization), 177 (19.3%) had incidental positive SARS-CoV-2 test results (asymptomatic or mild infection unrelated to the reason for hospitalization), and 25 (2.7%) had multisystem inflammatory syndrome in children (MIS-C), a rare but serious inflammatory condition associated with COVID-19.§§ Among the 713 patients hospitalized for COVID-19, 24.7% were aged <1 year, 17.1% were aged 1-4 years, 20.1% were aged 5-11 years, and 38.1% were aged 12-17 years. Approximately two thirds of patients (67.5%) had one or more underlying medical conditions, with obesity being the most common (32.4%); among patients aged 12-17 years, 61.4% had obesity. Among patients hospitalized for COVID-19, 15.8% had a viral coinfection¶¶ (66.4% of whom had respiratory syncytial virus [RSV] infection). Approximately one third (33.9%) of patients aged <5 years hospitalized for COVID-19 had a viral coinfection. Among 272 vaccine-eligible (aged 12-17 years) patients hospitalized for COVID-19, one (0.4%) was fully vaccinated.*** Approximately one half (54.0%) of patients hospitalized for COVID-19 received oxygen support, 29.5% were admitted to the intensive care unit (ICU), and 1.5% died; of those requiring respiratory support, 14.5% required invasive mechanical ventilation (IMV). Among pediatric patients with COVID-19-related hospitalizations, many had severe illness and viral coinfections, and few vaccine-eligible patients hospitalized for COVID-19 were vaccinated, highlighting the importance of vaccination for those aged ≥5 years and other prevention strategies to protect children and adolescents from COVID-19, particularly those with underlying medical conditions.

The effect of point-of-care ultrasound on length of stay in the emergency department in children with neck swelling.

BACKGROUND: Ultrasound is the imaging modality of choice in children presenting to the emergency department (ED) with soft tissue neck swelling. Point of care ultrasound (POCUS) has good accuracy when compared to comprehensive radiology department ultrasound (RADUS). POCUS could potentially improve ED length of stay (LOS) by improving efficiency. We aimed to evaluate the LOS of pediatric patients seen in ED with soft tissue neck swelling who received POCUS compared to RADUS. We determined unscheduled 30-day return visit rates in both groups as a balancing measure. METHODS: We performed a retrospective review of the electronic medical record for our cross-sectional study of discharged patients ≤21 years of age who had a neck ultrasound performed by a credentialed POCUS physician or by the radiology department between July 2014 and January 2020. We included patients who had both POCUS and RADUS in the POCUS group. We compared median ED LOS in both groups using the Mann Whitney U test and proportion of unscheduled return visits to the ED in both groups using odds ratio and 95% CI. RESULTS: There were 925 patients: 76 with only POCUS, 6 with POCUS and RADUS, and 843 with only RADUS performed. Median LOS in the POCUS group was 68.5 min (IQR 38.3120.3) versus 154.0 min (IQR 111.0, 211.0) in the RADUS group (p < 0.001). Return visit overall was 7.6%: 13.2% in the POCUS group versus 7.1% in the RADUS group (p = 0.07). CONCLUSION: Pediatric patients evaluated in the ED for soft tissue neck swelling had a shorter LOS with POCUS than with RADUS without a statistically significant increase in 30-day return visits. We suggest a "POCUS First" approach to the care of these patients.

Epinephrine autoinjector prescription filling after pediatric emergency department discharge.

Background: There are known racial and socioeconomic disparities in the use of epinephrine autoinjectors (EAI) for anaphylaxis. Objective: To measure the rates of EAI prescription filling and identify patient demographic factors associated with filling rates among patients discharged from the pediatric emergency department. Methods: This was a retrospective observational cohort study of all patients discharged from a pediatric emergency department who received an outpatient prescription for an EAI between January 1, 2018, and October 31, 2019. The rates of prescription filling were calculated, and multivariable logistic regression was performed to identify sociodemographic factors associated with prescription filling. Results: Of 717 patients included in the analysis, 54.8% (95% confidence interval {CI}, 51.1%-58.5%) filled their prescription. There were no significant associations between EAI fill rates and patient age or sex. In bivariable analysis, non-Hispanic white patients were more likely to fill EAI prescriptions compared with non-Hispanic Black patients (odds ratio [OR] 1.89 [95% CI, 1.11-3.20]), and patients with in-state Medicaid were significantly less likely to fill EAI prescriptions compared with those patients with private insurance (OR 0.69 [95% CI, 0.48-0.98]). However, after multivariable adjustment, there was no significant difference in filling by age, insurance status, or race or ethnicity. Conclusions: Only approximately half the patients had their EAI prescriptions filled after discharge. Filling rates did not vary by sociodemographic characteristics.

Quality Assurance for Point-of-Care Ultrasound in North American Pediatric Emergency Medicine Fellowships.

OBJECTIVES: The American Academy of Pediatrics, the Society for Academic Emergency Medicine, and the American College of Emergency Physicians released a policy statement endorsing the use of point-of-care ultrasound (POCUS) by pediatric emergency medicine (PEM) providers. This statement specifically recommends that emergency departments have a credentialing and quality assurance (QA) program for POCUS. There is limited knowledge of how QA for POCUS is currently carried out in pediatric emergency departments with PEM training programs. METHODS: We sent a cross-sectional web-based survey to all 81 PEM fellowship-training programs in the United States and Canada between June 2016 and June 2017. RESULTS: Sixty-six of 81 programs (81.2%) responded. Sixty-five percent of responding PEM training programs had POCUS-trained faculty or a POCUS champion at their institution. Forty-six percent had a POCUS fellowship in their institution, with 10 programs having PEM-specific POCUS fellowships. Programs with POCUS fellowships were more likely to save all images, review all scans, review scans more frequently, provide feedback, and bill compared with programs without POCUS fellowships. CONCLUSIONS: Point-of-care ultrasound is growing in PEM fellowship-training programs, with a majority of programs now having faculty members trained or interested specifically in POCUS. Most programs prefer more frequent and thorough QA processes, and programs with POCUS fellowships are more likely to have more frequent and thorough QA processes.

Practice Pattern Variation in Test Ordering for Low-Acuity Pediatric Emergency Department Patients.

OBJECTIVES: Rising costs in healthcare have focused attention on interventions to optimize efficiency of patient care, including decreasing unnecessary diagnostic testing. The primary objective of this study was to determine the variability of laboratory and radiology testing among licensed independent providers (LIPs) with different training backgrounds treating low-acuity patients in a pediatric emergency department (PED). METHODS: We performed a retrospective review of the electronic health records of all encounters with patients 21 years or younger, triaged as low-acuity, visiting 2 urban, academic PEDs from January 2012 to December 2013. We calculated frequency of orders for specific tests, including complete blood counts, aerobic blood cultures, urine cultures, and chest radiographs. Bivariable analyses were used to measure associations of test ordering between these LIP dyad groups: physician versus nurse practitioner (NP); physicians with pediatric emergency medicine fellowship training (PEM) versus physicians without PEM training and physicians with at least 5 years since residency graduation versus less than 5 years. We used multivariable logistic regression to adjust for potential confounders, including ED location, trainee co-management, and patient characteristics. We also performed sensitivity analyses by location. RESULTS: There were 148,570 total encounters treated by 12 NPs and 144 physicians, of whom 60 were PEM physicians. Seventy-three physicians had 5 or more years of experience. Testing rates per patient encounter ranged from 0% to 40% for individual providers. In bivariable analyses, testing was more likely when the LIP was a physician (odds ratio [OR] = 1.2, 95% confidence interval = 1.1-1.2) or PEM trained (OR = 1.3, 1.2-1.3). In multivariable analyses, testing was more likely for encounters with PEM providers (adjusted OR [AdjOR] = 1.2, 1.1-1.3). A sensitivity analysis on a subset of encounters seen exclusively at our PED-based urgent care revealed that testing was also more likely for encounters seen by PEM physicians (AdjOR = 1.5, 1.4-1.7) and with NPs (AdjOR = 1.2, 1.1-1.4) compared with physicians. CONCLUSIONS: Our study identified substantial variation in test ordering patterns for LIPs treating low-acuity patients. There were significant differences in ordering practices between providers from different training backgrounds, most significantly when comparing PEM with non-PEM providers. Further research should examine interventions to standardize practice across disciplines.

Implementing Paper Documentation During an Influenza Surge in a Pediatric Emergency Department.

OBJECTIVE: We hypothesized that a paper documentation and discharge bundle can expedite patient care during an influenza-related surge. METHODS: Retrospective cohort study of low-acuity patients younger than 21 years surging into a pediatric emergency department between January and March 2018 with influenza-like illness. Patient visits documented using a paper bundle were compared with those documented in the electronic medical record on the same date of visit. The primary outcome of interest was time from physician evaluation to discharge for patient visits documented using the paper bundle compared with those documented in the electronic medical record. Secondary outcome was difference in return visits within 72 hours. We identified patient and visit level factors associated with emergency department length of stay. RESULTS: A total of 1591 patient visits were included, 1187 documented in the electronic health record and 404 documented using the paper bundle. Patient visits documented using the paper bundle had a 21% shortened median time from physician evaluation to discharge (41 minutes; interquartile range, 27-62.8 minutes) as compared with patient visits documented in the electronic health record (52 minutes; interquartile range, 35-61 minutes; P < 0.001). There was no difference in return visits (odds ratio, 0.7; 95% confidence interval, 0.2, 2.2). CONCLUSIONS: Implementation of paper charting during an influenza-related surge was associated with shorter physician to discharge times when compared with patient visits documented in the electronic health record. A paper bundle may improve patient throughput and decrease emergency department overcrowding during influenza or coronavirus disease-related surge.

Impact of Transcervical Ultrasound for the Diagnosis of Pediatric Peritonsillar Abscesses on Emergency Department Performance Measures.

OBJECTIVES: To evaluate the impact of transcervical ultrasound (US) as the initial imaging study for suspected peritonsillar abscesses (PTAs) on pediatric emergency department (ED) throughput measures. METHODS: A retrospective cohort study of patients evaluated for suspected PTAs between January 2009 and April 2017 was conducted. We compared the ED length of stay (LOS) before and after implementation of transcervical US to diagnose a PTA. The balancing measure was the rate of return visits within 2 weeks. RESULTS: There were 387 eligible patients over the study period. A total of 101 patients were evaluated for PTAs with computed tomography and 286 with US. The mean LOS was significantly less for patients who had US (347 minutes; 95% confidence interval [CI], 330, 364 minutes) compared to computed tomography (426 minutes; 95% CI, 392, 459 minutes), with an absolute difference of 79 minutes (95% CI, 44, 113 minutes). Patients who were evaluated with US did not have an increased rate of return visits (5.9% versus 8.0%; P = .66). CONCLUSIONS: The introduction of transcervical US was associated with a decrease of greater than 1 hour in the ED LOS for patients with suspected PTAs. Given the better radiation profile of US and no increase in the rate of return visits after its implementation, we propose the adoption of a transcervical US-first approach for the diagnosis of PTAs in pediatrics.

Identifying Nonprovider Factors Affecting Pediatric Emergency Medicine Provider Efficiency.

OBJECTIVE: The aim of this study was to create a multivariable model of standardized relative value units per hour by adjusting for nonprovider factors that influence efficiency. METHODS: We obtained productivity data based on billing records measured in emergency relative value units for (1) both evaluation and management of visits and (2) procedures for 16 pediatric emergency medicine providers with more than 750 hours worked per year. Eligible shifts were in an urban, academic pediatric emergency department (ED) with 2 sites: a tertiary care main campus and a satellite community site. We used multivariable linear regression to adjust for the impact of shift and pediatric ED characteristics on individual-provider efficiency and then removed variables from the model with minimal effect on productivity. RESULTS: There were 2998 eligible shifts for the 16 providers during a 3-year period. The resulting model included 4 variables when looking at both ED sites combined. These variables include the following: (1) number of procedures billed by provider, (2) season of the year, (3) shift start time, and (4) day of week. Results were improved when we separately modeled each ED location. A 3-variable model using procedures billed by provider, shift start time, and season explained 23% of the variation in provider efficiency at the academic ED site. A 3-variable model using procedures billed by provider, patient arrivals per hour, and shift start time explained 45% of the variation in provider efficiency at the satellite ED site. CONCLUSIONS: Several nonprovider factors affect provider efficiency. These factors should be considered when designing productivity-based incentives.

Patients at High Risk of Intervention for Pediatric Traumatic Liver Injury.

OBJECTIVES: Nonoperative management of hemodynamically stable liver lacerations in pediatric trauma patients is a safe and effective management strategy for pediatric patients; approximately 90% will be successfully managed nonoperatively. No study has specifically identified risk criteria for the need for intervention versus observation alone. Our objective for this study was to determine risk factors from the physical examination, computed tomography scan, and laboratory results associated with intervention for liver laceration. METHODS: We performed a retrospective cohort study using data from the Pediatric Emergency Care Applied Research Network Intra-abdominal Injuries Study public use data set. Data were collected prospectively at the time of enrollment; a limited data set was released for public use in 2014. Patients were included if they were diagnosed with a liver laceration by computed tomography scan. We used bivariable and multivariable analyses to determine associations of specific risk factors with intervention, defined as laparotomy, angiographic embolization, blood transfusion, death, or return to emergency department for any reason within 30 days. RESULTS: Of the 12,044 patients in the Intra-abdominal Injuries Study, 282 were diagnosed with a liver laceration. All patients were hospitalized, and 99 (35.1%) underwent an intervention. Variables were then eliminated if more than 10% of cases were missing data. Multivariable logistic regression identified the following independent risk factors for intervention: white blood cell count greater than 15 K/mcl (adjusted odds ratio [adjOR], 2.83; 95% confidence interval [CI], 1.43-5.63), pelvic fracture (adjOR, 2.50; 95% CI, 1.02-6.10), liver injury greater than grade 2 (adjOR, 2.16; 95% CI, 1.06-4.40), Glasgow Coma Scale score less than 15 (adjOR, 4.77; 95% CI, 2.27-7.63), and hematocrit less than 32% (adjOR, 4.79; 95% CI, 2.00-11.46). CONCLUSIONS: We identified 5 high-risk criteria associated with intervention for traumatic liver laceration in pediatric patients. Prospective studies are necessary to validate these results before using them to determine disposition of pediatric patients with traumatic liver injuries.

Postpartum Depression Screening and Referral in a Pediatric Emergency Department.

OBJECTIVES: The aim of this study was to determine the (1) proportion of screened postpartum depression (PPD)-positive mothers, (2) associated risk factors, and (3) impact of PPD screening in a pediatric emergency department (PED). STUDY DESIGN: We performed a pilot cohort study using a convenience sample of mothers (n = 209, all ages) of infant patients 6 months or younger presenting to a PED. Mothers completed a computerized survey that included the Edinburgh Postnatal Depression Scale. We assessed frequency of positive screens and performed multivariable logistic regression to identify associated risk factors. We assessed maternal attitudes toward screening at enrollment and 1-month follow-up with positive-screen mothers. Differences in ED utilization were measured. RESULTS: Fifty-seven of 209 mothers (27%; 95% confidence interval [CI], 21%-33%) screened positive for PPD, with 14 (7%) reporting suicidal thoughts. Forty-seven percent (97/209) had never previously been screened, including 58% (33/57) of PPD screen-positive mothers. Current unemployment status (adjusted odds ratio [aOR], 2.76; 95% CI, 1.25-6.13) and first-time motherhood (aOR, 3.92; 95% CI, 1.72-8.91) were associated with a positive screen. At 1-month follow-up, mothers (35/37) reported PED-based PPD screening was important. After adjustment for sociodemographic factors, PPD screen-positive mothers had increased PED utilization (aOR, 1.29; 95% CI, 1.03-1.61). CONCLUSIONS: Approximately 1 in 4 mothers screened positive for PPD in a PED, with almost 1 in 10 reporting suicidal thoughts. The majority of PPD screen-positive mothers had not been screened previously. Our study helps to inform future efforts for interventions to support mothers of young infants who use the PED for care.

Utility of the DIVA score for experienced emergency department technicians.

BACKGROUND: The DIVA score is validated for predicting success of the initial attempt at peripheral intravenous insertion by nurses and physicians. A score of 4 or greater is 50% to 60% likely to have a failed first attempt. The study objective was to assess the validity of this score for emergency department technicians. METHODS: This study used a prospective convenience sample of 181 children presenting to the emergency department with intravenous access attempt by one of 29 emergency department technicians. DIVA score, total number of attempts, and median time to successful intravenous cannulation were obtained. RESULTS: Comparing patients with a DIVA score <4 to ≥4, first-time IV placement failure rates were lower (9% [95% CI, 3-24] vs. 41% [95% CI, 33-49]) and median time to IV placement was shorter (75 [interquartile range (IQR) 42-157] vs. 254 [IQR 91-806]) seconds. In patients with scores ≥4, emergency department technicians with ≥5 years of experience were significantly more likely to be successful on the first attempt (OR 2.8; 95% CI, 1.03-7.63). For every year of technician experience, the time to catheter placement, adjusted for DIVA score, decreased by 25 minutes (P≤0.05, R2=0.05). Comparing our receiver operating curve to the derivation study, the areas were similar (0.67 vs. 0.65). CONCLUSIONS: This study provides preliminary evidence for the validity of the DIVA score when applied to IVs placed by emergency department technicians. For patients with high DIVA scores, ≥5 years of IV experience was associated with higher odds of successful first-time IV placement and shorter time to placement. HIGHLIGHTS The difficult intravenous access (DIVA) score may be generalizable to IVs placed by experienced emergency department technicians (EDTs) Higher odds of first-time success in difficult patients with ≥5 years EDT experience Early identification of difficult access may allow for aid of alternative technology Likely first study to evaluate EDTs IV skills in patients with varying DIVA scores.

Evaluation of a Selective Prehospital Pediatric Spinal Protection Protocol.

Background: Recent studies demonstrate an association between spinal immobilization and neck pain, increased use of radiographs, and increased admission rates for pediatric trauma patients. There is an increasing trend toward spinal protection protocols that limit the use of backboards in trauma patients. However, many of these protocols do not address the youngest patients. Objectives: The objective was to analyze whether implementation of a selective prehospital pediatric spinal protection protocol was associated with a reduction in spinal imaging, hospital admission rates, and Emergency Department (ED) length of stay (LOS). Methods: We conducted a single center retrospective chart review to assess the effect of implementing a new selective pediatric spinal immobilization protocol in an EMS system. Patients transported to the same center from a neighboring EMS jurisdiction without a protocol change were analyzed for comparison. We extracted data for all pediatric patients with trauma-related discharge diagnoses transported by EMS to a pediatric trauma center for one year before and after the implementation of the protocol. Results: There were 878 eligible trauma patients transported under the new protocol, compared to 782 transported prior to implementation. We did not find a significant difference in the percentage of trauma patients who received spinal imaging pre- and post-protocol change (20% vs. 18%, OR 0.84 [95% CI 0.66, 1.07]), but did observe a significant reduction in the proportion of trauma patients who were admitted to the hospital (25% vs. 18%, OR 0.66 [95% CI 0.52, 0.83]). This reduced admission rate was not observed in the neighboring jurisdiction. Conclusions: Implementation of a selective spinal immobilization protocol was associated with reduced admission rates, but did not significantly reduce rates of plain radiographs.
