Impact of a hypothetical COVID-19 vaccine mandate on parental likelihood to vaccinate children: Exploring school-related concerns and vaccination decision-making.

OBJECTIVE: We assessed the impact of a hypothetical school-entry COVID-19 vaccine mandate on parental likelihood to vaccinate their child. METHODS: We collected demographics, COVID-19-related school concerns, and parental likelihood to vaccinate their child from parents of patients aged 3-16 years seen across nine pediatric Emergency Departments from 06/07/2021 to 08/13/2021. Wilcoxon signed-rank test compared pre- and post-mandate vaccination likelihood. Multivariate linear and logistic regression analyses explored associations between parental concerns with baseline and change in vaccination likelihood, respectively. RESULTS: Vaccination likelihood increased from 43% to 50% with a hypothetical vaccine mandate (Z = -6.69, p < 0.001), although most parents (63%) had no change, while 26% increased and 11% decreased their vaccination likelihood. Parent concerns about their child contracting COVID-19 was associated with greater baseline vaccination likelihood. No single school-related concern explained the increased vaccination likelihood with a mandate. CONCLUSION: Parental school-related concerns did not drive changes in likelihood to vaccinate with a mandate.

Factors Associated With Parental Acceptance of COVID-19 Vaccination: A Multicenter Pediatric Emergency Department Cross-Sectional Analysis.

STUDY OBJECTIVE: During the delta surge of the COVID-19 pandemic in 2021, we sought to identify characteristics and beliefs associated with COVID-19 vaccination acceptance in parents of pediatric emergency department (ED) patients. METHODS: We conducted a cross-sectional survey-based study of the parents of children aged 3 to 16 years presenting to 1 of 9 pediatric EDs from June to August 2021 to assess the parental acceptance of COVID-19 vaccines. Using multiple variable regression, we ascertained which factors were associated with parental and pediatric COVID-19 vaccination acceptance. RESULTS: Of 1,491 parents approached, 1,298 (87%) participated, of whom 50% of the parents and 27% of their children aged 12 years or older and older were vaccinated. Characteristics associated with parental COVID-19 vaccination were trust in scientists (adjusted odds ratio [aOR] 5.11, 95% confidence interval [CI] 3.65 to 7.15), recent influenza vaccination (aOR 2.66, 95% CI 1.98 to 3.58), college degree (aOR 1.97, 95% CI 1.36 to 2.85), increasing parental age (aOR 1.80, 95% CI 1.45 to 2.22), a friend or family member hospitalized because of COVID-19 (aOR 1.34, 95% CI 1.05 to 1.72), and higher income (aOR 1.60, 95% CI 1.27 to 2.00). Characteristics associated with pediatric COVID-19 vaccination (children aged ≥12 years) or intended COVID-19 pediatric vaccination, once approved for use, (children aged <12 years) were parental trust in scientists (aOR 5.37, 95% CI 3.65 to 7.88), recent influenza vaccination (aOR 1.89, 95% CI 1.29 to 2.77), trust in the media (aOR 1.68, 95% CI 1.19 to 2.37), parental college degree (aOR 1.49, 95% CI 1.01 to 2.20), and increasing parental age (aOR 1.26, 95% CI 1.01 to 1.57). CONCLUSION: Overall COVID-19 vaccination acceptance was low. Trust in scientists had the strongest association with parental COVID-19 vaccine acceptance for both themselves and their children.

Longitudinal evaluation of pediatric respiratory infections.

OBJECTIVE: Acute respiratory infections are the most common cause of under-five-year-old pediatric mortality worldwide. Due to a paucity of data, the impact of many respiratory viruses and their association with respiratory failure in children are unclear. We assessed single respiratory viral pathogens and their association with intubation, and secondly describe dual viral pathogens and viral-bacterial pathogens associations with intubation. PATIENT AND METHODS: This was a retrospective cross-sectional study of children (0-18 years old) admitted to the acute care unit and/or pediatric intensive care unit of an urban, quaternary children's hospital from November 1, 2013 to November 1, 2017. Patients with viral studies sent within 48 h of admission were included. Associations of viral pathogens and intubation status were calculated using odds ratios (OR), 95% confidence intervals (CI) and p-values. RESULTS: There were 15,923 hospitalization encounters, with 634 (3.9%) requiring intubation. RSV and hMPV had increased odds for intubation, (aOR 1.80, 95% CI 1.50-2.18) and (aOR 1.59, 95% CI 1.13-2.24) respectively. Coinfection with RSV and adenovirus had increased odds of requiring intubation, (aOR 3.48, 95% CI 1.21-10.01). Contrary, coinfection with influenza A and RSV had no intubations. In the viral-bacterial coinfections model, there was an increased association with intubations for RSV and Streptococcus (aOR 9.34, 95% CI 4.21-20.71) and hMPV and Streptococcus (aOR 8.98, 95% CI 1.62-49.88). CONCLUSION: RSV and hMPV corresponded to the highest rates of intubations, and dual infections with RSV and adenovirus, RSV and Streptococcus, and hMPV and Streptococcus were associated with mechanical ventilation, revealing differences amongst the groups.

Characteristics and Outcomes of Pediatric Rapid Response With a Respiratory Trigger.

BACKGROUND AND OBJECTIVES: Authors of adult rapid response (RRT) studies have established that RRT triggers play an important role in outcomes, but this association is not studied in pediatrics. In this study, we explore the characteristics and outcomes of pediatric rapid response with a respiratory trigger (Resp-RRT). We hypothesize that outcomes differ on the basis of patients' primary diagnoses at the time of Resp-RRT. METHODS: We conducted a 2-year retrospective observational study at an academic tertiary care pediatric hospital. RESULTS: Among the 1287 Resp-RRTs in 1060 patients, those with a respiratory diagnosis (N = 686) were younger, less likely to have complex chronic conditions, and less likely to have concurrent triggers (P < .01) than those with a nonrespiratory diagnosis (N = 601). Patients with a respiratory diagnosis were more likely to receive noninvasive ventilation, less likely to receive vasoactive support, and had lower 30-day mortality (P < .01). Among those with a respiratory diagnosis, the 541 patients with acute illness were younger, less likely to have complex chronic conditions, and less likely to receive vasoactive support than those with acute on chronic illness (N = 100) (P < .01). CONCLUSIONS: Among pediatric respiratory-triggered RRT events, patients with a respiratory diagnosis were more likely to receive acute respiratory support in ICU but have better long-term outcomes. Presence of complex chronic conditions increases risk of acute respiratory support and mortality. The interplay of primary diagnosis with RRT trigger can potentially inform resource needs and outcomes for pediatric Resp-RRTs.

An easy maneuver to screen for moderate-to-severe obstructive sleep spnea: the Simmons Chin Press and Tongue Curl.

OBJECTIVES: To demonstrate that the Simmons chin press and tongue curl (SCPTC) correlates with diagnosis of moderate-to-severe obstructive sleep apnea (msOSA) by itself as well as irrespective of the presence of other associated features. MATERIAL AND METHODS: A consecutive sample of 1,911 sleep studies performed on adult patients from 2/8/2017 to 3/5/2019 was analyzed. The SCPTC exam maneuver was performed on each patient, followed by home sleep apnea testing or in-laboratory polysomnography. The AASM hypopnea 1B 4% desaturation criteria were utilized for scoring to correlate results to existing literature on morbidity and mortality. A chi-squared using low and high SCPTC score was performed for the outcome of msOSA. Known significant predictors of OSA were dichotomized for comparison and a multiple logistic regression was performed. RESULTS: 1,708 patients qualified for inclusion: 902 males (52.8%) and 806 females (47.2%) with a mean age of 49.4 and a mean body mass index (BMI) of 28.6. A high SCPTC score correlated with an odds ratio (OR) of 2.49 (95% CI: 2.03-3.04, p<0.001) for msOSA. A multiple logistic regression analysis including other risk factors for msOSA demonstrated that high SCPTC scores had an odds ratio for msOSA of 1.77 (95% CI: 1.40-2.23; p<0.001). CONCLUSION: The SCPTC is a reproducible physical exam feature that can be utilized by healthcare providers to screen for patients with msOSA.

Focused Research Infrastructure for Postgraduate Pediatric Emergency Medicine Fellows Increases Dissemination of Scholarly Work.

BACKGROUND: Many fellows in clinically driven subspecialties may have difficulty completing and publishing their scholarly projects due to lack of prior experience in research, selection of projects that are difficult to complete during fellowship, or mentorship challenges. This may be particularly true in pediatric emergency medicine (PEM) because research time may be longitudinally integrated with clinical rotations, rather than blocked as is common in other subspecialties. We describe the creation and outcomes of a structured program to increase academic productivity of PEM fellows. METHODS: This was a retrospective cohort study of scholarly productivity (publications in peer-reviewed journals, presentation at national meetings) for PEM fellows over 17 years in one fellowship program, before and after the implementation of a structured program. We reviewed obstacles to publication for prior fellow projects when developing the curriculum. Our multifaceted program consisted of milestone development, four in-person committee meetings, and abstract and manuscript development workshops. We utilized existing faculty members, most of whom were junior faculty, as committee members. Our primary outcome was the percentage of fellows who were first authors for peer-reviewed publications for their fellowship projects. National conference presentations were the secondary outcome. RESULTS: Data for 76 PEM fellows were eligible for analysis: 44 (58%) before and 32 after programmatic implementation. There was a statistically significant increase in the percentage of fellows who published their studies (32% vs. 63%; odds ratio [OR] = 3.6, 95% confidence interval [CI] = 1.4 to 9.3) after programmatic implementation. There were no differences in conference presentations (45% vs. 63%; OR = 2.0, 95% CI = 0.8-5.1) after implementation. CONCLUSIONS: Utilizing a small group of existing, predominantly junior faculty members, we created a structured program that enhanced PEM fellows' scholarly productivity and increased publications. We believe that this model is sustainable for and generalizable to other PEM fellowship programs.

Respiratory Virus Co-infection in Acute Respiratory Infections in Children.

PURPOSE OF REVIEW: This investigation aims to understand the role and burden of viral co-infections for acute respiratory illnesses in children. Co-infection can be either viral-viral or viral-bacterial and with new technology there is more information on the role they play on the health of children. RECENT FINDINGS: With the proliferation of multiplex PCR for rapid diagnosis of multiple viruses as well as innovations on identification of bacterial infections, research has been attempting to discover how these co-infections affect each other and the host. Studies are aiming to discern if the epidemiology of viruses seen at a population level is related to the interaction between different viruses on a host level. Studies are also attempting to discover the burden of morbidity and mortality of these viral-viral co-infections on the pediatric population. It is also becoming important to understand the interplay of certain viruses with specific bacteria and understanding the impact of viral-bacterial co-infections. RSV continues to contribute to a large burden of disease for pediatric patients with acute respiratory illnesses. However, recent literature suggests that viral-viral co-infections do not add to this burden and might, in some cases, be protective of severe disease. Viral-bacterial co-infections, on the other hand, are most likely adding to the burden of morbidity in pediatric patients because of the synergistic way they can infect the nasopharyngeal space. Future research needs to focus on confirming these conclusions as it could affect hospital cohorting, role of molecular testing, and therapeutic interventions.

Clinical factors associated with intubation in the high flow nasal cannula era.

BACKGROUND: Bronchiolitis is the most common cause for hospitalization in infants. While the use of high flow nasal cannula (HFNC) has increased, it has not uniformly reduced intubation rates. OBJECTIVE: We identified factors associated with respiratory failure in children with bronchiolitis on HFNC. METHODS: We conducted a retrospective study of previously healthy children <24 months of age with bronchiolitis, who were treated with HFNC in two pediatric emergency departments from 1/2014-1/2018. The primary outcome was the identification of demographic and clinical factors that are associated with intubation after an antecedent trial of HFNC. A multivariable logistic regression model was constructed to identify predictors of respiratory failure. RESULTS: Of 2657 children on HFNC, the median age was 7 months, while the median age of the intubated cohort was 3 months. Ten percent (271) progressed to mechanical ventilation within 48 h of PED presentation. Of the 301 patients that needed escalation to CPAP and/or BiPAP, 91 required intubation. Factors associated with intubation were young age and a high respiratory tool score; factors associated with no progression to intubation were a reduction in tachycardia after initiation of HFNC and presentation after day 5 of illness. A secondary analysis also revealed decreased rate of intubation with the use of bronchodilators. We identified demographic, clinical, and therapeutic factors that are associated with requiring intubation. CONCLUSION: Given the high burden of bronchiolitis in pediatric emergency departments, these factors can be considered upon presentation of children with bronchiolitis to selectively identify children at higher risk for respiratory failure.

Prevalence of co-infection between respiratory syncytial virus and influenza in children.

BACKGROUND: Respiratory syncytial virus (RSV) and influenza have varying degree of seasonal overlap. OBJECTIVE: To determine the prevalence of co-infection of RSV and influenza compared to the prevalence of those infections independently when both are in season. METHODS: This was a retrospective cross-sectional study of children evaluated between July 2010 and June 2013 for viral respiratory infection using multiplex PCR. Seasonality was defined retrospectively as weeks when >2% of the total annual positive tests were obtained and was calculated for influenza A, influenza B, and RSV independently. Periods of overlapping seasonality of RSV and influenza A and RSV and influenza B were identified. The expected incidences of co-infection were modeled as the product of the incidences of the individual viruses. RESULTS: 13,664 specimens were sent for PCR during the study period. Over all 3 seasons, RSV overlapped with influenza A and B for 22 and 18weeks, respectively; in 2011-12, RSV overlapped with neither influenza A nor B. Based on modeling, there were 6-7 fold fewer cases of RSV/influenza co-infection observed than expected: RSV/influenza A 77 vs. 12, (p≤0.001; RSV/influenza B 76 vs. 11 (p≤0.001). CONCLUSIONS: The observed incidence of co-infectivity of RSV and influenza was significantly less than the expected incidence even when both were co-circulating. In light of these data, it may be reasonable to forgo rapid influenza testing or empiric antiviral treatment for children whom rapid RSV testing is positive and who are at low risk of influenza-related complications, especially in times of antiviral therapy shortages.
