<p>Early in the COVID-19 pandemic, CDC recommended collection of a lower respiratory tract (LRT) specimen for SARS-CoV-2 testing in addition to the routinely recommended upper respiratory tract (URT) testing in mechanically ventilated patients. Significant operational challenges were noted at our institution using this approach. In this report, we describe our experience with routine collection of paired URT and LRT sample testing. Our results revealed a high concordance between the two sources, and that all children tested for SARS-CoV-2 were appropriately diagnosed with URT testing alone. There was no added benefit to LRT testing. Based on these findings, our institutional approach was therefore adjusted to sample the URT alone for most patients, with LRT sampling reserved for patients with ongoing clinical suspicion for SARS-CoV-2 after a negative URT test.</p>
<p><strong>BACKGROUND: </strong>Understanding the prevalence and clinical presentation of COVID-19 in pediatric patients can help healthcare providers and systems prepare and respond to this emerging pandemic.</p>
<p><strong>METHODS: </strong>Retrospective case series of patients tested for SARS-CoV-2 across a pediatric healthcare network, including the clinical features and outcomes of those with positive test results.</p>
<p><strong>RESULTS: </strong>Of 7,256 unique children tested for SARS-CoV-2, 424 (5.8%) tested positive. Patients 18-21 years of age had the highest test positive rate (11.2%) while those 1-5 years of age had the lowest (3.9%). By race, 10.6% (226/2132) of Black children tested positive vs. 3.3% (117/3592) of White children. Of those with an indication for testing, 21.1% (371/1756) of patients with reported exposures or clinical symptoms tested positive vs. 3.8% (53/1410) of those undergoing pre-procedural or pre-admission testing. Of the 424 patients who tested positive for SARS-CoV-2, 182 (42.9%) had no comorbid medical conditions, 87 (20.5%) had asthma, 55 (13.0% had obesity, and 38 (9.0%) had mental health disorders. Overall, 52.1% had cough, 51.2% fever, and 14.6% shortness of breath. Seventy-seven (18.2%) SARS-CoV-2 positive patients were hospitalized, of which 24 (31.2%) required any respiratory support. SARS-CoV-2-targeted antiviral therapy was given to 9 patients, and immunomodulatory therapy to 18 patients. Twelve (2.8%) SARS-CoV-2 positive patients developed critical illness requiring mechanical ventilation and 2 patients required extracorporeal membrane oxygenation. Two patients died.</p>
<p><strong>CONCLUSIONS: </strong>In this large cohort of pediatric patients tested for SARS-CoV-2, the rate of infection was low, but varied by testing indication. The majority of cases were mild, few children had critical illness, and two patients died.</p>
<p><strong>BACKGROUND: </strong>Ventricular shunt complications in children can be severe and life-threatening if not identified and treated in a timely manner. Evaluation for shunt obstruction is not without risk, including lifetime cumulative radiation as patients routinely receive computed tomography (CT) scans of the brain and shunt series (multiple radiographs of the skull, neck, chest, and abdomen).</p>
<p><strong>METHODS: </strong>A multidisciplinary team collaborated to develop a clinical pathway with the goal of standardizing the evaluation and management of patients with suspected shunt complication. The team implemented a low-dose CT scan, specifically tailored for the detection of hydrocephalus and discouraged routine use of shunt series with single-view radiographs used only when specifically indicated.</p>
<p><strong>RESULTS: </strong>There was a reduction in the average CT effective dose (millisievert) per emergency department (ED) encounter of 50.6% (confidence interval, 46.0-54.9; P ≤ .001) during the intervention period. There was a significant reduction in the number of shunt surveys obtained per ED encounter, from 62.4% to 5.32% (P < .01). There was no significant change in the 72-hour ED revisit rate or CT scan utilization rate after hospital admission. There were no reports of inadequate patient evaluations or serious medical events.</p>
<p><strong>CONCLUSIONS: </strong>A new clinical pathway has rapidly reduced radiation exposure, both by reducing the radiation dose of CT scans and eliminating or reducing the number of radiographs obtained in the evaluation of patients with ventricular shunts without compromising clinical care.</p>
<p><strong>OBJECTIVE: </strong>To examine the effect of ambulatory health care processes on asthma hospitalizations.</p>
<p><strong>METHODS: </strong>A retrospective cohort study using electronic health records was completed. Patients aged 2-18 years receiving health care from 1 of 5 urban practices between Jan 1, 2004 and Dec 31, 2008 with asthma documented on their problem list were included. Independent variables were modifiable health care processes in the primary care setting: (1) use of asthma controller medications; (2) regular assessment of asthma symptoms; (3) use of spirometry; (4) provision of individualized asthma care plans; (5) timely influenza vaccination; (6) access to primary healthcare; and (7) use of pay for performance physician incentives. Occurrence of one or more asthma hospitalizations was the primary outcome of interest. We used a log linear model (Poisson regression) to model the association between the factors of interest and number of asthma hospitalizations.</p>
<p><strong>RESULTS: </strong>5,712 children with asthma were available for analysis. 96% of the children were African American. The overall hospitalization rate was 64 per 1,000 children per year. None of the commonly used asthma-specific indicators of high quality care were associated with fewer asthma hospitalizations. Children with documented asthma who experienced a lack of primary health care (no more than one outpatient visit at their primary care location in the 2 years preceding hospitalization) were at higher risk of hospitalization compared to those children with a greater number of visits (incidence rate ratio 1.39; 95% CI 1.09-1.78).</p>
<p><strong>CONCLUSIONS: </strong>In children with asthma, more frequent primary care visits are associated with reduced asthma hospitalizations.</p>
<p><strong>BACKGROUND: </strong>Candidemia causes significant morbidity and mortality among children. Removal of a central venous catheter (CVC) is often recommended for adults with candidemia to reduce persistent and metastatic infection. Pediatric-specific data on the impact of CVC retention are limited.</p>
<p><strong>METHODS: </strong>A retrospective cohort study of inpatients <19 years with candidemia at the Children's Hospital of Philadelphia between 2000 and 2012 was performed. The final cohort included patients that had a CVC in place at time of blood culture and retained their CVC at least 1 day beyond the blood culture being positive. A structured data collection instrument was used to retrieve patient data. A discrete time failure model, adjusting for age and the complexity of clinical care before onset of candidemia, was used to assess the association of CVC retention and 30-day all-cause mortality.</p>
<p><strong>RESULTS: </strong>Two hundred eighty-five patients with candidemia and a CVC in place at the time of blood culture were identified. Among these 285 patients, 30 (10%) died within 30 days. Central venous catheter retention was associated with a significant increased risk of death on a given day (odds ratio, 2.50; 95% confidence interval, 1.06-5.91).</p>
<p><strong>CONCLUSIONS: </strong>Retention of a CVC was associated with an increased risk of death after adjusting for age and complexity of care at candidemia onset. Although there is likely persistence of unmeasured confounding, given the strong association between catheter retention and death, our data suggest that early CVC removal should be strongly considered.</p>
<p><strong>BACKGROUND: </strong>The use of administrative data for surgical site infection (SSI) surveillance leads to inaccurate reporting of SSI rates [1]. A quality improvement (QI) initiative was conducted linking clinical registry and administrative databases to improve reporting and reduce the incidence of SSI [2].</p>
<p><strong>METHODS: </strong>At our institution, The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS-CHSD) and infection surveillance database (ISD) were linked to the enterprise data warehouse containing electronic health record (EHR) billing data. A data visualization tool was created to (1) use the STS-CHSD for case ascertainment, (2) resolve discrepancies between the databases, and (3) assess impact of QI initiatives, including wound alert reports, bedside reviews, prevention bundles, and billing coder education.</p>
<p><strong>RESULTS: </strong>Over the 24-month study period, 1,715 surgical cases were ascertained according to the STS-CHSD clinical criteria, with 23 SSIs identified through the STS-CHSD, 20 SSIs identified through the ISD, and 32 SSIs identified through the billing database. The rolling 12-month STS-CHSD SSI rate decreased from 2.73% (21 of 769 as of January 2013) to 1.11% (9 of 813 as of December 2014). Thirty reporting discrepancies were reviewed to ensure accuracy. Workflow changes facilitated communication and improved adjudication of suspected SSIs. Billing coder education increased coding accuracy and narrowed variation between the 3 SSI sources. The data visualization tool demonstrated temporal relationships between QI initiatives and SSI rate reductions.</p>
<p><strong>CONCLUSIONS: </strong>Linkage of registry and infection control surveillance data with the EHR improves SSI surveillance. The visualization tool and workflow changes facilitated communication, SSI adjudication, and assessment of the QI initiatives. Implementation of these initiatives was associated with decreased SSI rates.</p>
<p><strong>BACKGROUND: </strong>Outpatient respiratory tract infections are the most common reason for antibiotic prescribing to children. Although prior studies suggest that antibiotic overuse occurs, patient-specific data or data exploring the variability and determinants of variability across practices and practitioners is lacking.</p>
<p><strong>METHODS: </strong>This study was conducted from a retrospective cohort of encounters to 25 diverse pediatric practices with 222 clinicians, from January 1 to December 31, 2009. Diagnoses, medications, comorbid conditions, antibiotic allergy, and demographic data were obtained from a shared electronic health record and validated by manual review. Practice-specific antibiotic prescription and acute respiratory tract infection diagnosis rates were calculated to assess across-practice differences after adjusting for patient demographics and clustering of encounters within clinicians.</p>
<p><strong>RESULTS: </strong>A total of 102 102 (28%) of 399 793 acute visits by 208 015 patients resulted in antibiotic prescriptions. After adjusting for patient age, sex, race, and insurance type, and excluding encounters by patients with chronic conditions, antibiotic prescribing by practice ranged from 18% to 36% of acute visits, and the proportion of antibiotic prescriptions that were broad-spectrum ranged from 15% to 58% across practices, despite additional exclusion of patients with antibiotic allergies or prior antibiotic use. Diagnosis of (Dx) and broad-spectrum antibiotic prescribing (Broad) for acute otitis media (Dx: 8%-20%; Broad: 18%-60%), sinusitis (Dx: 0.5%-9%; Broad: 12%-78%), Streptococcal pharyngitis (Dx: 1.8%-6.4%; Broad: 2%-30%), and pneumonia (Dx: 0.4%-2%; Broad: 1%-70%) also varied by practice (P < 0.001 for all comparisons).</p>
<p><strong>CONCLUSIONS: </strong>Antibiotic prescribing for common pediatric infections varied substantially across practices. This variability could not be explained by patient-specific factors. These data suggest the need for and provide high-impact targets for outpatient antimicrobial stewardship interventions.</p>
