<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>

Vaccine exemption requirements and parental vaccine attitudes: an online experiment.

<p>Increases in vaccine hesitancy and vaccine-preventable disease outbreaks have focused attention on state laws governing school-entry vaccine mandates and the allowable exemptions (medical and nonmedical) from those mandates. There is substantial variation in the type of exemptions available in each state, and states with more rigorous or burdensome exemption requirements generally have lower exemption rates. States have little evidence, however, about how vaccine-hesitant parents respond to different requirements. Despite recent efforts to formulate "model legislation" templates for states to follow, policy evidence about optimal exemption regimes is limited to observational studies in states that have changed exemption laws. We conducted two online experiments to explore how parental attitudes and intentions responded to different school-entry vaccine mandate exemption requirements. We randomly assigned online participants to one of four hypothetical vaccine exemption application scenarios: parental signature only, a checklist of vaccines for which an exemption is requested, a lengthy (10-30+ min) video-based vaccine education module, and a requirement to write a statement justifying the exemption. Among parents with high vaccine hesitancy, a required vaccine education module led to significant decreases in vaccine hesitancy, while checklist and justification requirements increased vaccine hesitancy slightly. Among parents with low vaccine hesitancy, we observed a potential backfire effect when parents were required to write a justification statement. Our findings warrant replication in a larger, fully-powered trial to accelerate knowledge about how parents across the vaccine hesitancy spectrum respond to exemption regimes.</p>

Appropriateness of Antibiotic Prescribing in U.S. Children's Hospitals: A National Point Prevalence Survey.

2020

2020 Jan 16

1537-6591

<p><strong>BACKGROUND: </strong>Studies estimate that 30-50% of antibiotics prescribed for hospitalized patients are inappropriate, but pediatric data are limited. Characterization of inappropriate prescribing practices for children are needed to guide pediatric antimicrobial stewardship.</p>

<p><strong>METHODS: </strong>Cross-sectional analysis of antibiotic prescribing at 32 US children's hospitals. Subjects included hospitalized children with ≥1 antibiotic order at 0800 on one day per calendar quarter, over six quarters (Quarter 3 2016 - Quarter 4 2017). Antimicrobial stewardship program (ASP) physicians and/or pharmacists used a standardized survey to collect data on antibiotic orders and evaluate appropriateness. The primary outcome was the percentage of antibiotics prescribed for infectious use that were classified as suboptimal, defined as inappropriate or needing modification.</p>

<p><strong>RESULTS: </strong>Of 34 927 children hospitalized on survey days, 12 213 (35.0%) had ≥1 active antibiotic order. Among 11 784 patients receiving antibiotics for infectious use, 25.9% were prescribed ≥1 suboptimal antibiotic. Of the 17 110 antibiotic orders prescribed for infectious use, 21.0% were considered suboptimal. Most common reasons for inappropriate use were bug-drug mismatch (27.7%), surgical prophylaxis &gt;24 hours (17.7%), overly broad empiric therapy (11.2%), and unnecessary treatment (11.0%). The majority of recommended modifications were to stop (44.7%) or narrow (19.7%) the drug. ASPs would not have routinely reviewed 46.1% of suboptimal orders.</p>

<p><strong>CONCLUSIONS: </strong>Across 32 children's hospitals, approximately 1 in 3 hospitalized children are receiving one or more antibiotics at any given time. One quarter of these children are receiving suboptimal therapy, and nearly half of suboptimal use is not captured by current ASP practices.</p>

<p>Appendicitis is the most common pediatric surgical emergency and one of the most common indications for antibiotic use in hospitalized children. The antibiotic choice differs widely across children's hospitals, and the optimal regimen for perforated appendicitis remains unclear. We conducted a retrospective cohort study comparing initial antibiotic regimens for perforated appendicitis at a large tertiary-care children's hospital. Children hospitalized between January 2011 and March 2015 who underwent surgery for perforated appendicitis were identified by ICD-9 codes with confirmation by chart review. Patients were excluded if they had been admitted ≥48 hours prior to diagnosis, had a history of appendicitis, received inotropic agents, were immunocompromised, or were given an antibiotic regimen other than ceftriaxone plus metronidazole (CTX/MTZ) or an anti-pseudomonal drug (cefepime, piperacillin/tazobactam, ciprofloxacin, imipenem, or meropenem) within the first two days after diagnosis. The primary outcome of interest was post-operative complications, defined as development of an incisional infection or abscess within six weeks of hospital discharge. Of the 353 children who met the inclusion criteria, 252 (71%) received CTX/MTZ and the others received an anti-pseudomonal regimen. A post-operative complication occurred in 37 (14.7%) of the CTX/MTZ group versus 18 (17.8%) of the anti-pseudomonal group. Antibiotic-related complications occurred in 4.4% of children on CTX/MTZ and 6.9% of children on anti-pseudomonal antibiotics (p = 0.32). In a multivariable logistic regression model adjusting for sex, age, ethnicity, and duration of symptoms prior to presentation, the adjusted odds ratio for post-operative complications in children receiving anti-pseudomonal antibiotics was 1.25 (95% confidence interval 0.66-2.40). Post-operative complication rates did not differ for children treated with CTX/MTZ versus a broader-spectrum regimen.</p>

<p>We describe here treatment approaches and treatment-related complications in 138 hospitalized children with disseminated Lyme disease. The patients who received parenteral antibiotics had a higher rate of complications than those who received oral therapy (15.4 vs 4.2 per 1000 days of therapy, respectively; P &lt; .05). Oral therapy should be used preferentially if either route is supported by current guidelines.</p>

The impact of access to immunization information on vaccine acceptance in three countries.

2017

e0180759

2017

1932-6203

<p><strong>INTRODUCTION: </strong>Vaccine acceptance is a critical component of sustainable immunization programs, yet rates of vaccine hesitancy are rising. Increased access to misinformation through media and anti-vaccine advocacy is an important contributor to hesitancy in the United States and other high-income nations with robust immunization programs. Little is known about the content and effect of information sources on attitudes toward vaccination in settings with rapidly changing or unstable immunization programs.</p>

<p><strong>OBJECTIVE: </strong>The objective of this study was to explore knowledge and attitudes regarding vaccines and vaccine-preventable diseases among caregivers and immunization providers in Botswana, the Dominican Republic, and Greece and examine how access to information impacts reported vaccine acceptance.</p>

<p><strong>METHODS: </strong>We conducted 37 focus groups and 14 semi-structured interviews with 96 providers and 153 caregivers in Botswana, the Dominican Republic, and Greece. Focus groups were conducted in Setswana, English, Spanish, or Greek; digitally recorded; and transcribed. Transcripts were translated into English, coded in qualitative data analysis software (NVivo 10, QSR International, Melbourne, Australia), and analyzed for common themes.</p>

<p><strong>RESULTS: </strong>Dominant themes in all three countries included identification of health care providers or medical literature as the primary source of vaccine information, yet participants reported insufficient communication about vaccines was available. Comments about level of trust in the health care system and government contrasted between sites, with the highest level of trust reported in Botswana but lower levels of trust in Greece.</p>

<p><strong>CONCLUSIONS: </strong>In Botswana, the Dominican Republic, and Greece, participants expressed reliance on health care providers for information and demonstrated a need for more communication about vaccines. Trust in the government and health care system influenced vaccine acceptance differently in each country, demonstrating the need for country-specific data that focus on vaccine acceptance to fully understand which drivers can be leveraged to improve implementation of immunization programs.</p>

Variability in Antibiotic Prescribing for Community-Acquired Pneumonia.

2017

2017 Mar 07

1098-4275

<p><strong>BACKGROUND AND OBJECTIVES: </strong>Published guidelines recommend amoxicillin for most children with community-acquired pneumonia (CAP), yet macrolides and broad-spectrum antibiotics are more commonly prescribed. We aimed to determine the patient and clinician characteristics associated with the prescription of amoxicillin versus macrolide or broad-spectrum antibiotics for CAP.</p>

<p><strong>METHODS: </strong>Retrospective cohort study in an outpatient pediatric primary care network from July 1, 2009 to June 30, 2013. Patients prescribed amoxicillin, macrolides, or a broad-spectrum antibiotic (amoxicillin-clavulanic acid, cephalosporin, or fluoroquinolone) for CAP were included. Multivariable logistic regression models were implemented to identify predictors of antibiotic choice for CAP based on patient- and clinician-level characteristics, controlling for practice.</p>

<p><strong>RESULTS: </strong>Of 10 414 children, 4239 (40.7%) received amoxicillin, 4430 (42.5%) received macrolides and 1745 (16.8%) received broad-spectrum antibiotics. The factors associated with an increased odds of receipt of macrolides compared with amoxicillin included patient age ≥5 years (adjusted odds ratio [aOR]: 6.18; 95% confidence interval [CI]: 5.53-6.91), previous antibiotic receipt (aOR: 1.79; 95% CI: 1.56-2.04), and private insurance (aOR: 1.47; 95% CI: 1.28-1.70). The predicted probability of a child being prescribed a macrolide ranged significantly between 0.22 and 0.83 across clinics. The nonclinical characteristics associated with an increased odds of receipt of broad-spectrum antibiotics compared with amoxicillin included suburban practice (aOR: 7.50; 95% CI: 4.16-13.55) and private insurance (aOR: 1.42; 95% CI: 1.18-1.71).</p>

<p><strong>CONCLUSIONS: </strong>Antibiotic choice for CAP varied widely across practices. Factors unlikely related to the microbiologic etiology of CAP were significant drivers of antibiotic choice. Understanding drivers of off-guideline prescribing can inform targeted antimicrobial stewardship initiatives.</p>
