Influenza is associated with significant global morbidity and mortality, with vaccination being the primary preventive strategy. Despite recommendations, influenza vaccine uptake among healthcare providers (HCPs) remains suboptimal, especially in the Eastern Mediterranean. We aimed to assess the attitudes and practices of HCPs in Jordan regarding seasonal influenza vaccination and assess sources of variation thereof. We conducted a cross-sectional survey study among a sample of HCPs practicing in Jordan (12/29/2020-04/26/2021). Participants completed a questionnaire assessing demographics, influenza vaccination history, attitudes, and practices. We used logistic regression to evaluate factors related to vaccine receipt and reasons for non-vaccination. We used proportional odds models to evaluate factors related to HCP recommendations and to compare opinions on influenza vaccination between ever- and never-vaccinated HCPs. Of 305 survey initiates, 206 HCPs (67.5%) comprised the analytic sample. The median age was 35 years; 61.2% were women, and 43.7% were pharmacists. Over half (52.9%) never received an influenza vaccine; however, older age and self-identifying as a physician were associated with higher odds of having ever received the influenza vaccine. The main reasons for non-vaccination were related to the misassessment of risks and benefits. Prior receipt of influenza vaccination was strongly associated with odds of recommending vaccination (or = 10.5; 95% CI = [5.38-20.3]; p<0.001). The COVID-19 pandemic reportedly enhanced influenza vaccine acceptance among 48.5% of HCPs surveyed. Low influenza vaccine uptake among healthcare providers in Jordan is related to misassessment of risks and benefits. Enhancing attitudes and confidence through tailored education is crucial to overcoming hesitancy and promoting sustained improvements in vaccination attitudes and practices among HCPs in Jordan.

In developing countries where point-of-care testing is limited, providers rely on clinical judgement to discriminate between viral and bacterial respiratory infections. We performed a cross-sectional cohort study of hospitalized Jordanian children to evaluate antibiotic use for respiratory syncytial virus (RSV) infections. Admitting diagnoses from a prior viral surveillance cohort of hospitalized Jordanian children were dichotomized into suspected viral-like, non-pulmonary bacterial-like, and pulmonary bacterial-like infection. Stratifying by sex, we performed a polytomous logistic regression adjusting for age, underlying medical condition, maternal education, and region of residence to estimate prevalence odds ratios (PORs) for antibiotic use during hospitalization. Sensitivity and specificity of admission diagnoses and research laboratory results were compared. Children with a suspected viral-like admission diagnosis, compared to those with suspected non-pulmonary bacterial-like, were 88% and 86% less likely to be administered an empiric/first-line antibiotic (male, aPOR: 0.12; female, aPOR: 0.14; p-value = <0.001). There were slight differences by sex with males having a lower prevalence than females in being administered an expanded coverage antibiotic; but they had a higher prevalence of macrolide administration than males with non-pulmonary bacterial-like infection. Overall, children with RSV had a 34% probability (sensitivity) of being assigned to a suspected viral-like diagnosis; whereas RSV-negative children had a 76% probability (specificity) of being assigned to a suspected pulmonary bacterial-like diagnosis. Hospitalized children with a suspected viral-like admission diagnosis were less likely to receive an empiric/first-line and expanded coverage antibiotic compared to suspected non-pulmonary and pulmonary infections; however, when evaluating the accuracy of admission diagnosis to RSV-laboratory results there were considerable misclassifications. These results highlight the need for developing antibiotic interventions for Jordan and the rest of the Middle East.

Background and Aims Respiratory syncytial virus (RSV) is a leading cause of acute respiratory infection (ARI) in children, particularly in low‐ and middle‐income countries. Rapid diagnosis is important for management and infection control. We aimed to evaluate diagnostic accuracy of Sofia 2 RSV fluorescent immunoassay (FIA) compared to reverse‐transcription quantitative PCR (RT‐qPCR) in children under 2 years hospitalized with ARI in Amman, Jordan. Methods We conducted a prospective viral surveillance study from January 26, 2020 to March 17, 2020, at Al‐Bashir Hospital. Sofia 2 RSV FIA was performed on nasal swabs and compared to RT‐qPCR. We calculated sensitivity, specificity, and Cohen's κ with 95% confidence intervals and assessed factors associated with RSV detection by FIA using logistic regression. Results Of 458 children enrolled, 356 (77.7%) had RSV detected by RT‐qPCR. Sofia 2 RSV FIA demonstrated 76.1% sensitivity (95% CI: 71.3, 80.5%) and 94.1% specificity (95% CI: 87.6, 97.8%) relative to RT‐qPCR. Lower RT‐qPCR cycle threshold value (inversely related to viral load) was significantly associated with Sofia 2 RSV FIA positivity (aOR = 0.75; 95% CI: 0.70, 0.81; p < 0.001). Conclusion Sofia 2 RSV FIA demonstrates potential as a rapid diagnostic test in resource‐limited settings. Further research on its clinical outcomes and cost‐effectiveness could enhance RSV management in children.

ABSTRACT IMPACT: Antibiotic stewardship guidelines should consider the barriers clinicians in low- and middle-income countries face due to limited biomarkers for determining the etiologic pathogen for viral infections like respiratory syncytial virus (RSV) that have a similar presentation to bacterial infections. OBJECTIVES/GOALS: We aimed to evaluate antibiotic administration practices in children who were hospitalized at a government-run hospital in Amman, Jordan, where point-of-care testing is limited. We hypothesized those with RSV are more likely to be administered antibiotics during their hospitalization than children without RSV. METHODS/STUDY POPULATION: We conducted a cross-sectional cohort study in Jordanian children hospitalized with history of acute respiratory symptoms and/or fever from 2010 to 2013. Admitting diagnoses were dichotomized into suspected viral- (e.g., bronchiolitis) and bacterial-like infection (e.g., sepsis, pneumonia). Stratifying by sex, we performed a polytomous logistic regression adjusting for age, underlying medical condition, maternal education, and region of residence to estimate prevalence odds ratios (PORs) and 95% confidence intervals for macrolides, broad-, and narrow-spectrum antibiotics during hospitalization. Sensitivity and specificity of admission diagnoses and laboratory results were compared. RESULTS/ANTICIPATED RESULTS: Children with a suspected viral-like admission diagnosis, compared to those with suspected bacterial-like, were 89% less likely to be administered a narrow-spectrum antibiotic (POR: 0.11; p<0.001). There were slight differences by sex with males having a lower prevalence than females of narrow-spectrum or broad-spectrum antibiotic administration; but they had a higher prevalence of macrolide administration. Overall, children with RSV had a 30% probability (sensitivity) of being assigned to a suspected viral infection; whereas RSV-negative children had an 85% probability (specificity) of being assigned to a suspected bacterial infection. DISCUSSION/SIGNIFICANCE OF FINDINGS: Children with a suspected viral-like infection were less likely to receive an antibiotic; however, when evaluating the accuracy of admission diagnosis to RSV-laboratory results there were considerable misclassifications. These results highlight the need for developing antibiotic interventions for Jordan and the rest of the Middle East.

Despite national recommendations, antiviral prescribing in emergency departments (EDs) for children at higher risk of severe influenza, such as those younger than 5 years and those with specific underlying conditions, remains low. To assess whether there were changes in antiviral prescribing for children at higher risk of severe influenza in academic pediatric EDs before the COVID-19 pandemic (2016-2020) vs the late pandemic period (2021-2023). This multicenter, cross-sectional study included influenza-positive children younger than 18 years presenting to the ED at 1 of 7 US pediatric academic hospitals participating in the Centers for Disease Control and Prevention's New Vaccine Surveillance Network. The analysis focused on children at higher risk of severe influenza seen in the ED from December 1, 2016, to June 30, 2023. High risk of severe influenza. The primary outcome was antiviral prescribing. Children with influenza who met the criteria for higher risk of severe influenza were included. Antiviral prescribing practices were compared across the prepandemic and late pandemic periods. Mixed-effects logistic regression was used to identify factors associated with prescribing during the late pandemic period. Of 3378 influenza-positive children (median [IQR] age, 3.9 [1.8-7.2] years), 2514 (74.4%; 1363 male [40.3%]) were classified as having higher risk of severe influenza during the prepandemic and late pandemic periods. Antiviral prescriptions decreased from 32.2% (622 of 1931 children) before the pandemic to 15.6% (91 of 583 children) in the late pandemic period, representing a 53% relative decrease. In the late pandemic period, symptom duration less than 2 days (adjusted odds ratio, 4.08; 95% CI, 2.49-6.71) and clinical influenza testing (adjusted odds ratio, 17.20; 95% CI, 4.08-72.37) were significantly associated with antiviral prescribing. This multicenter, cross-sectional study of children with influenza in EDs found that, for children at higher risk of severe influenza illness, influenza antiviral prescribing decreased during the COVID-19 pandemic compared with prepandemic levels, despite unchanged treatment guidelines. Interventions are needed to support guideline-concordant prescribing in this population.
