US Emergency Department Visits for Adverse Drug Events From Antibiotics in Children, 2011-2015

Improving Antibiotic Prescribing for Children with Community-acquired Pneumonia in Outpatient Settings

OBJECTIVE

To assess whether a two-phase intervention was associated with improvements in antibiotic prescribing among nonhospitalized children with community-acquired pneumonia.

STUDY DESIGN

In a large health care organization, a first intervention phase was implemented in September 2020 directed at antibiotic choice and duration for children 2 months through 17 years of age with pneumonia. Activities included clinician education and implementation of a pneumonia-specific order set in the electronic health record. In October 2021, a second phase comprised additional education and order set revisions. A narrow spectrum antibiotic (eg, amoxicillin) was recommended in most circumstances. Electronic health record data were used to identify pneumonia cases and antibiotics ordered. Using interrupted time series analyses, antibiotic choice and duration after phase one (September 2020-September 2021) and after phase two (October 2021-October 2022) were compared with a preintervention prepandemic period (January 2016-early March 2020).

RESULTS

Overall, 3570 cases of community-acquired pneumonia were identified: 3246 cases preintervention, 98 post-phase one, and 226 post-phase two. The proportion receiving narrow spectrum monotherapy increased from 40.6% preintervention to 68.4% post-phase one to 69.0% post-phase two (P < .001). For children with an initial narrow spectrum antibiotic, duration decreased from preintervention (mean duration 9.9 days, SD 0.5 days) to post-phase one (mean 8.2, SD 1.9) to post-phase two (mean 6.8, SD 2.3) periods (P < .001).

CONCLUSIONS

A two-phase intervention with educational sessions combined with clinical decision support was associated with sustained improvements in antibiotic choice and duration among children with community-acquired pneumonia.

Outcomes of antibiotic treatment for respiratory infections in children an observational study in primary care

BACKGROUND

Antibiotic resistance is an increasing global threat, accelerated by both misuse and overuse of antibiotics. Most antibiotics to humans are prescribed in primary care, commonly for respiratory symptoms, and there is a need for research on the usage of and outcomes after antibiotic treatment to counteract antibiotic resistance.

OBJECTIVE

To evaluate symptom duration, treatment length, and adverse events of antibiotic treatment in children.

DESIGN AND SETTING

Observational study at four out-of-hours services and one paediatric emergency clinic in Norwegian emergency primary care.

SUBJECTS

266 children aged 0 to 6 years with fever or respiratory symptoms.

MAIN OUTCOME MEASURES

Duration of symptoms and absenteeism from kindergarten/school, treatment length, and reported adverse events.

RESULTS

There were no differences in duration of symptoms, fever or absenteeism when comparing the groups prescribed (30.8%) and not prescribed (69.2%) antibiotics. This lack of difference remained when analysing the subgroup with otitis media.In the group prescribed antibiotics, 84.5% of parents reported giving antibiotics for 5-7 days, and 50.7% reported no difficulties. Adverse events of antibiotics were reported in 42.3% of the cases, the vast majority being gastrointestinal disturbances.

CONCLUSION

Children with fever or respiratory symptoms experience similar duration of symptoms and absenteeism regardless of antibiotic treatment. A substantial number of parents reported adverse events when the child received antibiotics. Several parents experienced additional difficulties with the treatment, some ending treatment within day 4.

Outcomes associated with initial narrow-spectrum versus broad-spectrum antibiotics in children hospitalized with urinary tract infections

OBJECTIVE

The aim of this study is to describe the proportion of children hospitalized with urinary tract infections (UTIs) who receive initial narrow- versus broad-spectrum antibiotics across children's hospitals and explore whether the use of initial narrow-spectrum antibiotics is associated with different outcomes.

DESIGN, SETTING AND PARTICIPANTS

We performed a retrospective cohort analysis of children aged 2 months to 17 years hospitalized with UTI (inclusive of pyelonephritis) using the Pediatric Health Information System (PHIS) database.

MAIN OUTCOME AND MEASURES

We analyzed the proportions of children initially receiving narrow- versus broad-spectrum antibiotics; additionally, we compiled antibiogram data for common uropathogenic organisms from participating hospitals to compare with the observed antibiotic susceptibility patterns. We examined the association of antibiotic type with adjusted outcomes including length of stay (LOS), costs, and 7- and 30-day emergency department (ED) revisits and hospital readmissions.

RESULTS

We identified 10,740 hospitalizations for UTI across 39 hospitals. Approximately 5% of encounters demonstrated initial narrow-spectrum antibiotics, with hospital-level narrow-spectrum use ranging from <1% to 25%. Approximately 80% of hospital antibiograms demonstrated >80% Escherichia coli susceptibility to cefazolin. In adjusted models, those who received initial narrow-spectrum antibiotics had shorter LOS (narrow-spectrum: 33.1 (95% confidence interval [CI]: 30.8-35.4) h versus broad-spectrum: 46.1 (95% CI: 44.1-48.2) h) and reduced costs [narrow-spectrum: $4570 ($3751-5568) versus broad-spectrum: $5699 ($5005-$6491)]. There were no differences in ED revisits or hospital readmissions. In summary, children's hospitals have low rates of narrow-spectrum antibiotic use for UTIs despite many reporting high rates of cefazolin-susceptible E. coli. These findings, coupled with the observed decreased LOS and costs among those receiving narrow-spectrum antibiotics, highlight potential antibiotic stewardship opportunities.

Antibiotic Use in Korean Children Diagnosed With Acute Bronchiolitis: Analysis of the National Health Insurance Reimbursement Data

BACKGROUND

Acute bronchiolitis, the most common lower respiratory tract infection in infants, is mostly caused by respiratory viruses. However, antibiotics are prescribed to about 25% of children with acute bronchiolitis. This inappropriate use of antibiotics for viral infections induces antibiotic resistance. This study aimed to determine the antibiotic prescription rate and the factors associated with antibiotic use in children with acute bronchiolitis in Korea, where antibiotic use and resistance rates are high.

METHODS

Healthcare data of children aged < 24 months who were diagnosed with acute bronchiolitis between 2016 and 2019 were acquired from the National Health Insurance system reimbursement claims data. Antibiotic prescription rates and associated factors were evaluated.

RESULTS

A total of 3,638,424 visits were analyzed. The antibiotic prescription rate was 51.8%, which decreased over time (P < 0.001). In the multivariate analysis, toddlers (vs. infants), non-capital areas (vs. capital areas), primary clinics and non-tertiary hospitals (vs. tertiary hospitals), inpatients (vs. outpatients), and non-pediatricians (vs. pediatricians) showed a significant association with antibiotic prescription (P < 0.001). Fourteen cities and provinces in the non-capital area exhibited a wide range of antibiotic prescription rates ranging from 41.2% to 65.4%, and five (35.7%) of them showed lower antibiotic prescription rates than that of the capital area.

CONCLUSION

In Korea, the high antibiotic prescription rates for acute bronchiolitis varied by patient age, region, medical facility type, clinical setting, and physician specialty. These factors should be considered when establishing strategies to promote appropriate antibiotic use.

Understanding the role of antibiotic-associated adverse events in influencing antibiotic decision-making

Objective

To (1) understand the role of antibiotic-associated adverse events (ABX-AEs) on antibiotic decision-making, (2) understand clinician preferences for ABX-AE feedback, and (3) identify ABX-AEs of greatest clinical concern.

Design

Focus groups.

Setting

Academic medical center.

Participants

Medical and surgical house staff, attending physicians, and advanced practice practitioners.

Methods

Focus groups were conducted from May 2022 to December 2022. Participants discussed the role of ABX-AEs in antibiotic decision-making and feedback preferences and evaluated the prespecified categorization of ABX-AEs based on degree of clinical concern. Thematic analysis was conducted using inductive coding.

Results

Four focus groups were conducted (n = 15). Six themes were identified. (1) ABX-AE risks during initial prescribing influence the antibiotic prescribed rather than the decision of whether to prescribe. (2) The occurrence of an ABX-AE leads to reassessment of the clinical indication for antibiotic therapy. (3) The impact of an ABX-AE on other management decisions is as important as the direct harm of the ABX-AE. (4) ABX-AEs may be overlooked because of limited feedback regarding the occurrence of ABX-AEs. (5) Clinicians are receptive to feedback regarding ABX-AEs but are concerned about it being punitive. (6) Feedback must be curated to prevent clinicians from being overwhelmed with data. Clinicians generally agreed with the prespecified categorizations of ABX-AEs by degree of clinical concern.

Conclusions

The themes identified and assessment of ABX-AEs of greatest clinical concern may inform antibiotic stewardship initiatives that incorporate reporting of ABX-AEs as a strategy to reduce unnecessary antibiotic use.

Clinical Course of Children 1 to 24 Months Old With Positive Urine Cultures Without Pyuria

OBJECTIVE

To describe the clinical course of children with positive urine cultures without pyuria who were not given antibiotics initially, identify predictors of subsequent antibiotic treatment, and evaluate the association between subsequent treatment and urinary tract infection (UTI) within 30 days.

METHODS

We conducted a multicenter retrospective cohort study of children 1 to 24 months old who had positive urine cultures without pyuria and who were not started on antibiotics upon presentation to 3 health care systems from 2010 to 2021. Outcomes included clinical status at the time urine cultures resulted, escalation of care (emergency department visit or hospitalization) and subsequent antibiotic treatment within 7 days, and subsequent UTI within 30 days of presentation.

RESULTS

Of 202 included children, 61% were female and median age was 9 months. Of 151 patients with clinical status information when cultures resulted, 107 (70.8%, 95% confidence interval [CI] 62.9-77.9%) were improved. Two of 202 children (1.0%, 95% CI 0.2-4.0%) experienced care escalation. Antibiotics were started in 142 (82.2%) children, and treatment was associated with prior UTI (risk ratio [RR] 1.20, 95% CI 1.15-1.26) and lack of improvement (RR 1.22, 95% CI 1.13-1.33). Subsequent UTI was diagnosed in 2 of 164 (1.2%, 95% CI 0.1-4.3%) treated and 0 of 36 (0%, 95% CI 0-9.7%) untreated children.

CONCLUSIONS

Seventy percent of children with positive urine cultures without pyuria improved before starting antibiotics; however, >80% were ultimately treated. Future research should study the impact of diagnostic stewardship interventions and various urine testing strategies to optimize the management of children evaluated for UTI.retain-->.

Parent and Clinician Views on Not Using Antibiotics for Mild Community-Acquired Pneumonia

OBJECTIVES

Preschool-aged children with mild community-acquired pneumonia (CAP) routinely receive antibiotics even though most infections are viral. We sought to identify barriers to the implementation of a "no antibiotic" strategy for mild CAP in young children.

METHODS

Qualitative study using semistructured interviews conducted in a large pediatric hospital in the United States from January 2021 to July 2021. Parents of young children diagnosed with mild CAP in the previous 3 years and clinicians practicing in outpatient settings (pediatric emergency department, community emergency department, general pediatrics offices) were included.

RESULTS

Interviews were conducted with 38 respondents (18 parents, 20 clinicians). No parent heard of the no antibiotic strategy, and parents varied in their support for the approach. Degree of support related to their desire to avoid unnecessary medications, trust in clinicians, the emotional difficulty of caring for a sick child, desire for relief of suffering, willingness to accept the risk of unnecessary antibiotics, and judgment about the child's illness severity. Eleven (55%) clinicians were familiar with guidelines specifying a no antibiotic strategy. They identified challenges in not using antibiotics, including diagnostic uncertainty, consequences of undertreatment, parental expectations, follow-up concerns, and acceptance of the risks of unnecessary antibiotic treatment of many children if it means avoiding adverse outcomes for some children.

CONCLUSIONS

Although both parents and clinicians expressed broad support for the judicious use of antibiotics, pneumonia presents stewardship challenges. Interventions will need to consider the emotional, social, and logistical aspects of managing pneumonia, in addition to developing techniques to improve diagnosis.

New insights into the treatment of acute otitis media

INTRODUCTION

Acute otitis media (AOM) affects most (80%) children by 5 years of age and is the most common reason children are prescribed antibiotics. The epidemiology of AOM has changed considerably since the widespread use of pneumococcal conjugate vaccines, which has broad-reaching implications for management.

AREAS COVERED

In this narrative review, we cover the epidemiology of AOM, best practices for diagnosis and management, new diagnostic technology, effective stewardship interventions, and future directions of the field. Literature review was performed using PubMed and ClinicalTrials.gov.

EXPERT OPINION

Inaccurate diagnoses, unnecessary antibiotic use, and increasing antimicrobial resistance remain major challenges in AOM management. Fortunately, effective tools and interventions to improve diagnostic accuracy, de-implement unnecessary antibiotic use, and individualize care are on the horizon. Successful scaling of these tools and interventions will be critical to improving overall care for children.

Prevalence and Predictors of Using Antibiotics without a Prescription in a Pediatric Population in the United States

Non-prescription antibiotic use (using antibiotics without clinical guidance) increases the risk of the development of antibiotic resistance, adverse drug reactions, and other potential patient harm. Few studies have explored non-prescription use in children in the U.S. From January 2021 to April 2022, a diverse sample of caregivers of children under 18 years were surveyed in English and Spanish at two safety net clinics in Texas. We assessed the prevalence of antibiotic use in children in the previous 12 months, storage of antimicrobials, and intended use of non-prescription antibiotics (professed intention for future non-prescription antibiotic use). We also measured sociodemographic factors, types of antibiotics used, and symptoms that trigger non-prescription use. The response rate was 82%, and 17% were surveyed in Spanish. Of 322 participants surveyed, three Spanish-speaking caregivers reported giving non-prescription antibiotics to their child in the previous 12 months. Approximately 21% (n = 69) reported storing antimicrobials at home, specifically amoxicillin (n = 52), clindamycin (n = 10), cephalexin (n = 5), penicillin (n = 3), and trimethoprim/sulfamethoxazole (n = 3). Nearly 15% (n = 46) reported intention to give non-prescription antibiotics to their children. Younger caregiver age was associated with storage and intended use of non-prescription antibiotics. Our findings will guide the development of an educational intervention to decrease non-prescription antibiotic use.

Adverse effects of antibiotics in children with cancer: are short-course antibiotics for febrile neutropenia part of the solution?

INTRODUCTION

Febrile neutropenia is a common complication experienced by children with cancer or those undergoing hematopoietic stem cell transplantation. Repeated episodes of febrile neutropenia result in cumulative exposure to broad-spectrum antibiotics with potential for a range of serious adverse effects. Short-course antibiotics, even in patients with high-risk febrile neutropenia, may offer a solution.

AREAS COVERED

This review addresses the known broad effects of antibiotics, highlights developments in understanding the relationship between cancer, antibiotics, and the gut microbiome, and discusses emerging evidence regarding long-term adverse antibiotic effects. The authors consider available evidence to guide the duration of empiric antibiotics in pediatric febrile neutropenia and directions for future research.

EXPERT OPINION

Broad-spectrum antibiotics are associated with antimicrobial resistance, Clostridioides difficile infection, invasive candidiasis, significant disturbance of the gut microbiome and may seriously impact outcomes in children with cancer or undergoing allogenic hematopoietic stem cell transplant. Short-course empiric antibiotics are likely safe in most children with febrile neutropenia and present a valuable opportunity to reduce the risks of antibiotic exposure.

Antibiotic Indications and Appropriateness in the Pediatric Intensive Care Unit: A 10-Center Point Prevalence Study

BACKGROUND

Antibiotics are prescribed to most pediatric intensive care unit (PICU) patients, but data describing indications and appropriateness of antibiotic orders in this population are lacking.

METHODS

We performed a multicenter point prevalence study that included children admitted to 10 geographically diverse PICUs over 4 study days in 2019. Antibiotic orders were reviewed for indication, and appropriateness was assessed using a standardized rubric.

RESULTS

Of 1462 patients admitted to participating PICUs, 843 (58%) had at least 1 antibiotic order. A total of 1277 antibiotic orders were reviewed. Common indications were empiric therapy for suspected bacterial infections without sepsis or septic shock (260 orders, 21%), nonoperative prophylaxis (164 orders, 13%), empiric therapy for sepsis or septic shock (155 orders, 12%), community-acquired pneumonia (CAP; 118 orders, 9%), and post-operative prophylaxis (94 orders, 8%). Appropriateness was assessed for 985 orders for which an evidence-based rubric for appropriateness could be created. Of these, 331 (34%) were classified as inappropriate. Indications with the most orders classified as inappropriate were empiric therapy for suspected bacterial infection without sepsis or septic shock (78 orders, 24%), sepsis or septic shock (55 orders, 17%), CAP (51 orders, 15%), ventilator-associated infections (47 orders, 14%), and post-operative prophylaxis (44 orders, 14%). The proportion of antibiotics classified as inappropriate varied across institutions (range, 19%-43%).

CONCLUSIONS

Most PICU patients receive antibiotics. Based on our study, we estimate that one-third of antibiotic orders are inappropriate. Improved antibiotic stewardship and research focused on strategies to optimize antibiotic use in critically ill children are needed.

Antibiotic use and outcomes among children hospitalized with suspected pneumonia

BACKGROUND

Although viral etiologies predominate, antibiotics are frequently prescribed for community-acquired pneumonia (CAP).

OBJECTIVE

We evaluated the association between antibiotic use and outcomes among children hospitalized with suspected CAP.

DESIGNS, SETTINGS AND PARTICIPANTS

We performed a secondary analysis of a prospective cohort of children hospitalized with suspected CAP.

INTERVENTION

The exposure was the receipt of antibiotics in the emergency department (ED).

MAIN OUTCOME AND MEASURES

Clinical outcomes included length of stay (LOS), care escalation, postdischarge treatment failure, 30-day ED revisit, and quality-of-life (QoL) measures from a follow-up survey 7-15 days post discharge. To minimize confounding by indication (e.g., radiographic CAP), we performed inverse probability treatment weighting with propensity analyses.

RESULTS

Among 523 children, 66% were <5 years, 88% were febrile, 55% had radiographic CAP, and 55% received ED antibiotics. The median LOS was 41 h (IQR: 25, 54). After propensity analyses, there were no differences in LOS, escalated care, treatment failure, or revisits between children who received antibiotics and those who did not. Seventy-one percent of patients completed follow-up surveys after discharge. Among 16% of patients with fevers after discharge, the median fever duration was 2 days, and those who received antibiotics had a 37% decrease in the mean number of days with fever (95% confidence interval: 20% and 51%). We found no statistical differences in other QoL measures.

Predictors of Acute Care Reutilization in Pediatric Patients With Amoxicillin-Associated Reactions

BACKGROUND

Amoxicillin-associated reactions (AARs) contribute to substantial health care utilization, with a reutilization rate of 10% in pediatric emergency department (ED) and urgent care (UC) settings.

OBJECTIVE

To identify predictors of ED/UC reutilization by examining patients' clinical features and providers' management of AARs.

METHODS

Through a retrospective chart review of 668 patients presenting with AARs over 2 years to the pediatric ED/UC, we examined clinical features associated with ED/UC reutilization, including rash phenotype, systemic symptoms (fever, angioedema, joint involvement, gastrointestinal symptoms), and providers' management (pharmacologic treatment and counseling). We then constructed a statistical model to predict ED/UC reutilization using stepwise backward model selection.

RESULTS

ED/UC reutilizers were more likely to be male (P = .008) and have fever (P = .0001), angioedema (P < .0001), joint involvement (P < .0001), and gastrointestinal symptoms (P = .0001) during their AAR course. Rash phenotypes differed between groups (P < .0001), as ED/UC reutilizers more frequently exhibited urticaria. However, there were no differences in clinical management between groups, including pharmacologic recommendations, at the initial ED/UC encounter. In addition, our statistical model identified younger patients <2 years of age as more likely to reutilize ED/UC resources if providers did not document specific return precautions (odds ratio, 3.6; 95% confidence interval, 1.7-7.7).

CONCLUSION

Recognition of clinical features and treatment gaps associated with ED/UC reutilization will guide interventions to optimize care in children presenting with AARs, such as improved anticipatory guidance and early allergy consultation. Prospective studies are needed to determine whether these interventions will reduce ED/UC reutilization and facilitate timely allergy testing.

Variation in bacterial pneumonia diagnoses and outcomes among children hospitalized with lower respiratory tract infections

BACKGROUND

Current diagnostics do not permit reliable differentiation of bacterial from viral causes of lower respiratory tract infection (LRTI), which may lead to over-treatment with antibiotics for possible bacterial community-acquired pneumonia (CAP).

OBJECTIVES

We sought to describe variation in the diagnosis and treatment of bacterial CAP among children hospitalized with LRTIs and determine the association between CAP diagnosis and outcomes.

DESIGN, SETTING AND PARTICIPANTS

This multicenter cross-sectional study included children hospitalized between 2017 and 2019 with LRTIs at 42 children's hospitals.

MAIN OUTCOME AND METHODS

We calculated the proportion of children with LRTIs who were diagnosed with and treated for bacterial CAP. After adjusting for confounders, hospitals were grouped into high, moderate, and low CAP diagnosis groups. Multivariable regression was used to examine the association between high and low CAP diagnosis groups and outcomes.

RESULTS

We identified 66,581 patients hospitalized with LRTIs and observed substantial variation across hospitals in the proportion diagnosed with and treated for bacterial CAP (median 27%, range 12%-42%). Compared with low CAP diagnosing hospitals, high diagnosing hospitals had higher rates of CAP-related revisits (0.6% [95% confidence interval: 0.5, 0.7] vs. 0.4% [0.4, 0.5], p = .04), chest radiographs (58% [53, 62] vs. 46% [41, 51], p = .02), and blood tests (43% [33, 53] vs. 26% [19, 35], p = .046). There were no significant differences in length of stay, all-cause revisits or readmissions, CAP-related readmissions, or costs.

CONCLUSION

There was wide variation across hospitals in the proportion of children with LRTIs who were treated for bacterial CAP. The lack of meaningful differences in clinical outcomes among hospitals suggests that some institutions may over-diagnose and overtreat bacterial CAP.

Antibiotic Prescribing Patterns for Pediatric Urgent Care Clinicians

OBJECTIVE

Previous studies have reported high rates of inappropriate antibiotic prescriptions in urgent care (UC). Specific prescribing patterns for the most common diagnoses are not known. The aim of the study is to determine the diagnoses for which antibiotics are prescribed in pediatric UC settings.

METHODS

We recruited pediatric UC providers via email to participate in a national multisite quality improvement study. Participants completed a survey on 10 consecutive encounters in which an antibiotic was given between March and May 2018. Encounters in which only topical antibiotics were prescribed were excluded. We categorized the encounters into 3 previously established tiers to determine appropriateness of antibiotic use. The tiers represent a descending order for antibiotic need based on diagnoses, with the first tier representing diagnoses almost always requiring antibiotics and the third tier representing diagnoses when an antibiotic is almost never required. We reported the diagnoses and frequency of antibiotic prescription within each tier.

RESULTS

The 157 providers from 20 institutions submitted a total of 2809 encounters. We excluded 339 encounters in which only topical antibiotics were prescribed. Most diagnoses fell into the tier 2 category (85.81%), with only 9.12% in tier 1 and 5.06% in tier 3. The most common diagnoses reported were acute otitis media (48.96%), pharyngitis (25.09%), and skin and soft tissue infections (7.29%).

CONCLUSIONS

In this sample of pediatric UC encounters, only 5% of diagnoses receiving antibiotic prescriptions were made up of tier 3 diagnoses, determined to almost never require antibiotics. While viral respiratory infections have been reported to frequently be treated with antibiotics in general UC centers, our study of pediatric UC centers showed that this was infrequent. However, otitis media with effusion and otalgia should be further investigated. With most antibiotic prescriptions being tier 2 diagnoses, pediatric UC providers can use evidence-based prescribing practices, shared decision making, and contingency plans to reduce unnecessary antibiotic exposure.

Prescribed medicine use and extent of off-label use according to age in a nationwide sample of Australian children

BACKGROUND

Medicine prescribing for children is impacted by a lack of paediatric-specific dosing, efficacy and safety data for many medicines.

OBJECTIVES

To estimate the prevalence of medicine use among children and the rate of 'off-label' prescribing according to age at dispensing.

METHODS

We used population-wide primarily outpatient dispensing claims data for 15% of Australian children (0-17 years), 2013-2017 (n = 840,190). We estimated prescribed medicine use and 'off-label' medicine use according to the child's age (<1 year, 1-5 years, 6-11 years, 12-17 years) defined as medicines without age-appropriate dose recommendations in regulator-approved product information. Within off-label medicines, we also identified medicines with and without age-specific dose recommendations in a national prescribing guide, the Australian Medicines Handbook Children's Dosing Companion (AMH CDC).

RESULTS

The overall dispensing rate was 2.0 dispensings per child per year. The medicines with the highest average yearly prevalence were systemic antibiotics (435.3 per 1000 children), greatest in children 1-5 years (546.9 per 1000). Other common medicine classes were systemic corticosteroids (92.7 per 1000), respiratory medicines (91.2 per 1000), acid-suppressing medicines in children <1 year (47.2 per 1000), antidepressants in children 12-17 years (40.3 per 1000) and psychostimulants in children 6-11 years (27.0 per 1000). We identified 12.2% of dispensings as off-label based on age, but 66.3% of these had age-specific dosing recommendations in the AMH CDC. Among children <1 year, off-label dispensings were commonly acid-suppressing medicines (35.5%) and topical hydrocortisone (33.1%); in children 6-11 years, off-label prescribing of clonidine (16.0%) and risperidone (13.1%) was common. Off-label dispensings were more likely to be prescribed by a specialist (21.7%) than on-label dispensings (7.5%).

CONCLUSIONS

Prescribed medicine use is common in children, with off-label dispensings for medicines without paediatric-specific dosing guidelines concentrated in classes such as acid-suppressing medicines and psychotropics. Our findings highlight a need for better evidence to support best-practice prescribing.

Factors Associated With Antibiotic Use for Children Hospitalized With Pneumonia

BACKGROUND

Antibiotics are frequently used for community-acquired pneumonia (CAP), although viral etiologies predominate. We sought to determine factors associated with antibiotic use among children hospitalized with suspected CAP.

METHODS

We conducted a prospective cohort study of children who presented to the emergency department (ED) and were hospitalized for suspected CAP. We estimated risk factors associated with receipt of ≥1 dose of inpatient antibiotics and a full treatment course using multivariable Poisson regression with an interaction term between chest radiograph (CXR) findings and ED antibiotic use. We performed a subgroup analysis of children with nonradiographic CAP.

RESULTS

Among 477 children, 60% received inpatient antibiotics and 53% received a full course. Factors associated with inpatient antibiotics included antibiotic receipt in the ED (relative risk 4.33 [95% confidence interval, 2.63-7.13]), fever (1.66 [1.22-2.27]), and use of supplemental oxygen (1.29 [1.11-1.50]). Children with radiographic CAP and equivocal CXRs had an increased risk of inpatient antibiotics compared with those with normal CXRs, but the increased risk was modest when antibiotics were given in the ED. Factors associated with a full course were similar. Among patients with nonradiographic CAP, 29% received inpatient antibiotics, 21% received a full course, and ED antibiotics increased the risk of inpatient antibiotics.

CONCLUSIONS

Inpatient antibiotic utilization was associated with ED antibiotic decisions, CXR findings, and clinical factors. Nearly one-third of children with nonradiographic CAP received antibiotics, highlighting the need to reduce likely overuse. Antibiotic decisions in the ED were strongly associated with decisions in the inpatient setting, representing a modifiable target for future interventions.

Drug-Related Hypersensitivity Reactions Leading to Emergency Department: Original Data and Systematic Review

The aim of the present study is to describe pharmacological characteristics of drug-related allergies and anaphylaxis leading to the emergency department (ED). An 8-year post hoc analysis on the MEREAFaPS Study database was performed (2012−2019). Subjects who experienced drug-related hypersensitivity leading to an ED visit were selected. Logistic regression analyses were used to estimate the reporting odds ratios (RORs) of drug-related allergies and anaphylaxis adjusting for sex, age classes, and ethnicity. In addition, a systematic review of observational studies evaluating drug-related hypersensitivity reactions leading to ED visits in outpatients was performed. Out of 94,073 ED visits, 14.4% cases were drug-related allergies and 0.6% were anaphylaxis. Females accounted for 56%. Multivariate logistic regression showed a higher risk of drug-related allergy among males and all age classes < 65 years, while a higher risk of anaphylaxis was observed for females (ROR 1.20 [1.01−1.42]) and adults (ROR 2.63 [2.21−3.14]). The systematic review included 37 studies. ED visits related to allergy and anaphylaxis ranged from 0.004% to 88%, and drug-related allergies and anaphylaxis ranged from 0.007% to 88%. Both in our analysis and in primary studies, antibacterials, analgesics, and radiocontrast agents were identified as the most common triggers of hypersensitivity.

Association of Inappropriate Outpatient Pediatric Antibiotic Prescriptions With Adverse Drug Events and Health Care Expenditures

IMPORTANCE

Nonguideline antibiotic prescribing for the treatment of pediatric infections is common, but the consequences of inappropriate antibiotics are not well described.

OBJECTIVE

To evaluate the comparative safety and health care expenditures of inappropriate vs appropriate oral antibiotic prescriptions for common outpatient pediatric infections.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study included children aged 6 months to 17 years diagnosed with a bacterial infection (suppurative otitis media [OM], pharyngitis, sinusitis) or viral infection (influenza, viral upper respiratory infection [URI], bronchiolitis, bronchitis, nonsuppurative OM) as an outpatient from April 1, 2016, to September 30, 2018, in the IBM MarketScan Commercial Database. Data were analyzed from August to November 2021.

EXPOSURES

Inappropriate (ie, non-guideline-recommended) vs appropriate (ie, guideline-recommended) oral antibiotic agents dispensed from an outpatient pharmacy on the date of infection.

MAIN OUTCOMES AND MEASURES

Propensity score-weighted Cox proportional hazards models were used to estimate hazards ratios (HRs) and 95% CIs for the association between inappropriate antibiotic prescriptions and adverse drug events. Two-part models were used to calculate 30-day all-cause attributable health care expenditures by infection type. National-level annual attributable expenditures were calculated by scaling attributable expenditures in the study cohort to the national employer-sponsored insurance population.

RESULTS

The cohort included 2 804 245 eligible children (52% male; median [IQR] age, 8 [4-12] years). Overall, 31% to 36% received inappropriate antibiotics for bacterial infections and 4% to 70% for viral infections. Inappropriate antibiotics were associated with increased risk of several adverse drug events, including Clostridioides difficile infection and severe allergic reaction among children treated with a nonrecommended antibiotic agent for a bacterial infection (among patients with suppurative OM, C. difficile infection: HR, 6.23; 95% CI, 2.24-17.32; allergic reaction: HR, 4.14; 95% CI, 2.48-6.92). Thirty-day attributable health care expenditures were generally higher among children who received inappropriate antibiotics, ranging from $21 to $56 for bacterial infections and from -$96 to $97 for viral infections. National annual attributable expenditure estimates were highest for suppurative OM ($25.3 million), pharyngitis ($21.3 million), and viral URI ($19.1 million).

CONCLUSIONS AND RELEVANCE

In this cohort study of children with common infections treated in an outpatient setting, inappropriate antibiotic prescriptions were common and associated with increased risks of adverse drug events and higher attributable health care expenditures. These findings highlight the individual- and national-level consequences of inappropriate antibiotic prescribing and further support implementation of outpatient antibiotic stewardship programs.

Synergistic effect of Mahaenggamseok-tang in the treatment of pediatric patients with lower respiratory tract infections: A PRISMA-compliant systematic review and meta-analysis

BACKGROUND

Infants are often hospitalized because of lower respiratory tract infections, and overuse of antibiotics to treat such infections has led to severe problems. Herbal medicines may be more effective and safer than antibiotics. Mahaenggamseok-tang is a common herbal medicine in Asia, but the evidence for its effectiveness in lower respiratory tract infection treatment is insufficient. This review assesses the efficacy of Mahaenggamseok-tang in treating lower respiratory tract infections.

METHODS

The study used Chinese, English, and Korean databases, as well as one Japanese database. All included studies were randomized controlled trials comparing Mahaenggamseok-tang with medication to treat lower respiratory tract infections. Studies using Mahaenggamseok-tang plus Western medicine were also included. Standardized mean difference (SMD), risk ratio (RR) with 95% confidence interval (CI), and risk of bias were analyzed using Review Manager 5.4 software. The GRADEpro website was used to assess the reviews.

RESULTS

Seventeen randomized controlled trials with a total of 1993 participants were included in the meta-analysis. All studies compared the Mahaenggamseok-tang plus Western medicine group to the Western medicine only group. Meta-analysis showed that Mahaenggamseok-tang affected total effective rate (risk ratio: 1.20, 95% confidence interval [CI]: 1.10-1.31, P < .001), cough disappearance time (SMD: -1.62, 95% CI: -2.30 to -0.95, P < .001), fever disappearance time (SMD: -2.04, 95% CI: -2.87 to -1.21, P < .001), abnormal lung sound disappearance time (SMD: -1.68, 95% CI: -2.43 to -0.93, P < .001), Creactive protein (SMD: -3.18, 95% CI: -4.36 to -1.99, P < .001), procalcitonin (SMD: -5.04, 95% CI: -9.20 to -0.88, P < .05), tumor necrosis factor-α (SMD: -0.84, 95% CI: -1.46 to -0.23, P < .01), IgE (SMD: -2.69, 95% CI: -2.91 to -2.47, P < .001), and adverse events (risk ratio: 0.44, 95% CI: 0.29-0.68, P < .001), but not interleukin-6 (SMD: -1.59, 95% CI: -3.48 to 0.30, P>.05).

DISCUSSION

Mahaenggamseok-tang plus Western medicine is more effective and safer than Western medicine alone for treating lower respiratory tract infections. However, the included randomized controlled trials were not randomized well; therefore, better randomized randomized controlled trials are needed to make significant recommendations.PROSPERO registration number: CRD42020165698.

Antibiotic Use and Outcomes in Young Children Hospitalized with Uncomplicated Community-Acquired Pneumonia

Background

We aimed to compare children aged 36 months or younger hospitalized with uncomplicated community-acquired pneumonia (CAP) who are not treated with antibiotics to those treated with antibiotics in terms of clinical features and outcome measures.

Methods

Administrative data and medical record review were used to identify patients from 3 to 36 months of age hospitalized from 2011 to 2019 with uncomplicated CAP. Patients were considered treated if they received antibiotics for >2 inpatient days and/or at discharge, and not treated if they received ≤2 inpatient days and no antibiotics at discharge. Untreated patients were compared to treated patients based on demographic features, clinical and laboratory results, and outcomes of interest, including illness severity, length of stay, and 30-day hospital readmissions.

Results

Three hundred twenty-two CAP cases were included; 266 (83%) received antibiotics for >48 hours and/or at discharge. Fifty-six patients received ≤2 inpatient days of antibiotics and no antibiotics at discharge; the majority received no inpatient antibiotics. There were no differences between the 2 groups in illness severity, length of stay, or hospital readmissions. The proportion of patients treated with antibiotics decreased from 88% (2011–2013) to 66% during the most recent years studied (2017–2019).

Conclusions

There was no difference in outcome of uncomplicated CAP in previously healthy children <36 months of age between those treated and not treated with antibiotics. Additional tools are needed to facilitate identification of viral CAP in young children and decrease unnecessary antibiotic use.

Analysis of serious adverse events in a pediatric community-acquired pneumonia randomized clinical trial in Malawi

Amoxicillin is recommended as first-line antibiotic treatment for community-acquired pneumonia, the leading infectious cause of mortality in children aged less than 5 years. We conducted a double-blind, randomized controlled non-inferiority trial comparing 3- to 5-day amoxicillin treatment for non-severe chest-indrawing pneumonia in HIV-negative children aged 2 to 59 months in Malawi. In a secondary analysis, we assessed the frequency of serious adverse events (SAEs) during the trial to evaluate the safety of treatment with amoxicillin. Enrolled children with non-severe chest-indrawing pneumonia were randomized to either 3- or 5-day amoxicillin and followed for 14 days to track clinical outcomes. In addition to evaluation for treatment failure (primary endpoint, day 6), relapse, and study drug adherence, children were assessed for adverse events, including SAEs, which were managed per local standard clinical practice until resolution or stabilization. Between March 2016 and April 2019, 3000 children were enrolled, with male and younger children (aged less than 24 months) demonstrating more SAEs (10.3% for males vs 8.1% for females, p = 0.04; 10.0% for 2–6 months, 10.8% for 7–11 months, 9.7% for 12–23 months and 5.6% for 24–59 months, p = 0.01). The most common SAEs were progression of or recurrent pneumonia (220 SAEs in 217 children), acute gastroenteritis (14 SAEs in 14 children), and fever (8 SAEs in 8 children); however, there were no significant or substantive differences in the percentage of children with pneumonia-related, acute gastroenteritis, or fever SAEs noted between the 3- versus 5-day amoxicillin treatment groups. In our pediatric community-acquired pneumonia trial evaluating amoxicillin treatment, there were relatively few SAEs overall and very few attributed to amoxicillin. Duration of amoxicillin treatment did not impact the frequency of SAEs. We found male and younger children appear to be more vulnerable to SAEs in our trial; however, our data support previous data demonstrating the safety of amoxicillin use in children with pneumonia.

COVID-19 and Antibiotic Prescribing in Pediatric Primary Care

BACKGROUND AND OBJECTIVES

With the onset of the coronavirus disease 2019 (COVID-19) pandemic, pediatric ambulatory encounter volume and antibiotic prescribing both decreased; however, the durability of these reductions in pediatric primary care in the United States has not been assessed.

METHODS

We conducted a retrospective observational study to assess the impact of the COVID-19 pandemic and associated public health measures on antibiotic prescribing in 27 pediatric primary care practices. Encounters from January 1, 2018, through June 30, 2021, were included. The primary outcome was monthly antibiotic prescriptions per 1000 patients. Interrupted time series analysis was performed.

RESULTS

There were 69 327 total antibiotic prescriptions from April through December in 2019 and 18 935 antibiotic prescriptions during the same months in 2020, a 72.7% reduction. The reduction in prescriptions at visits for respiratory tract infection (RTI) accounted for 87.3% of this decrease. Using interrupted time series analysis, overall antibiotic prescriptions decreased from 31.6 to 6.4 prescriptions per 1000 patients in April 2020 (difference of -25.2 prescriptions per 1000 patients; 95% CI: -32.9 to -17.5). This was followed by a nonsignificant monthly increase in antibiotic prescriptions, with prescribing beginning to rebound from April to June 2021. Encounter volume also immediately decreased, and while overall encounter volume quickly started to recover, RTI encounter volume returned more slowly.

CONCLUSIONS

Reductions in antibiotic prescribing in pediatric primary care during the COVID-19 pandemic were sustained, only beginning to rise in 2021, primarily driven by reductions in RTI encounters. Reductions in viral RTI transmission likely played a substantial role in reduced RTI visits and antibiotic prescriptions.

Antibiotics in critically ill children-a narrative review on different aspects of a rational approach

Especially critically ill children are exposed to antibiotic overtreatment, mainly caused by the fear of missing out a severe bacterial infection. Potential adverse effects and selection of multi-drug resistant bacteria play minor roles in decision making. This narrative review first describes harm from antibiotics and second focuses on different aspects that could help to reduce antibiotic overtreatment without harming the patient: harm from antibiotic treatment, diagnostic approaches, role of biomarkers, timing of antibiotic therapy, empiric therapy, targeted therapy, and therapeutic drug monitoring. Wherever possible, we linked the described evidence to the current Surviving Sepsis Campaign guidelines. Antibiotic stewardship programs should help guiding antibiotic therapy for critically ill children. IMPACT: Critically ill children can be harmed by inadequate or overuse of antibiotics. Hemodynamically unstable children with a suspicion of infection should be immediately treated with broad-spectrum antibiotics. In contrast, in hemodynamically stable children with sepsis and organ dysfunction, a time frame of 3 h for proper diagnostics may be adequate before starting antibiotics if necessary. Less and more targeted antibiotic treatment can be achieved via antibiotic stewardship programs.

Antibiotic use for asymptomatic bacteriuria in children with neurogenic bladder

PURPOSE

Patients with neurogenic bladder (NB) often perform clean intermittent catheterization (CIC) and are predisposed to bladder colonization. Antibiotics are not routinely indicated in those with asymptomatic bacteriuria (ASB). The original purpose of this study was to compare patients that received antibiotics for ASB and those that did not. However, because the non-antibiotic group was very small, the final analysis evaluated treatment patterns of ASB in children with NB.

METHODS

A retrospective chart review was completed, including patients who presented with urinary tract infection (UTI) and NB managed by CIC. Patients with symptoms of UTI were excluded. Basic demographics, urinalysis, culture results, and antibiotic prescriptions were collected.

RESULTS

The sample included 272 patient encounters for 109 unique patients. Of these, 50.7% were female, and the median age was 10.25 years. More than half the urine cultures (56.2%) grew gram-negative organisms, and 31.3% contained 2 or more organisms. Nearly all encounters received treatment with antibiotics. Twenty-three encounters with no culture performed or the culture resulted in no growth received antibiotic therapy.

CONCLUSIONS

Antibiotic resistance and antibiotic stewardship are primary concerns in healthcare today. This organization's current practice pattern shows high antibiotic use for ASB in patients with NB. Future studies are required to identify outcomes associated with treatment versus non-treatment in these patients.

Group A Streptococcal Pharyngitis Testing Appropriateness in Pediatric Acute Care Settings

OBJECTIVE

Acute pharyngitis is one of the most common causes of ambulatory clinic visits; however, group A Streptococcus accounts for less than a third. National guidelines recommend against streptococcal testing in patients with viral features. This study aims to assess the rate of inappropriate streptococcal rapid antigen detection tests (RADT)s in children evaluated in urgent care clinics (UCC)s and emergency department (ED)s at a children's hospital.

METHODS

We retrospectively reviewed charts of 10% of children 3 years or older with RADTs ordered between April and September 2018 at EDs and UCCs. The test was determined to be inappropriate if the patient had no sore throat and/or had 2 or more viral symptoms: rhinorrhea/congestion, cough, diarrhea, hoarseness, conjunctivitis, or viral exanthem.

RESULTS

Over the study period, 7678 RADTs were performed, of which 7024 (91.2%) were in children 3 years or older. We evaluated 708 charts and found 44% of RADTs were inappropriate. The predicted probability of inappropriate RADT was highest among patients with a triaged reason for visit for respiratory complaints (70.5%), viral upper respiratory tract infection (69.7%), and rash (61.3%). Of the inappropriate RADTs, 20.1% were positive, whereas 32.2% of the appropriate RADTs were positive.

CONCLUSION

Quality improvement initiatives are needed to decrease the rate of inappropriate RADTs in pediatric UCC and ED settings.

Considerations for implementation: Pediatric outpatient antimicrobial stewardship program

It is encouraging that most acute care centers have formal antimicrobial stewardship (AS) programs; though, most antibiotic use occurs in outpatient settings where access to infectious diseases specialists are limited. Stewardship programs often target dichotomous populations (adult or pediatric), but most children receive care in nonacademic, community outpatient settings. We propose 3 considerations for adult providers and infection preventionists seeking to incorporate outpatient AS elements and implement quality improvement initiatives that optimize pediatric care.

Factors Associated With Antibiotic Prescribing and Outcomes for Pediatric Pneumonia in the Emergency Department

OBJECTIVES

Chest radiographs (CXRs) are often performed in children with respiratory illness to inform the decision to prescribe antibiotics. Our objective was to determine the factors associated with clinicians' plans to treat with antibiotics prior to knowledge of CXR results and the associations between preradiograph plans with antibiotic prescription and return to medical care.

METHODS

Previously healthy children aged 3 months to 18 years with a CXR for suspected pneumonia were enrolled in a prospective cohort study in the emergency department. Our primary outcomes were antibiotic prescription or administration in the emergency department and medical care sought within 7 to 15 days after discharge. Inverse probability treatment weighting was used to limit bias due to treatment selection. Inverse probability treatment weighting was included in a logistic regression model estimating the association between the intention to give antibiotics and outcomes.

RESULTS

Providers planned to prescribe antibiotics prior to CXR in 68 children (34.9%). There was no difference in the presence of radiographic pneumonia between those with and without a plan for antibiotics. Children who had a plan for antibiotics were more likely to receive antibiotics than those without (odds ratio [OR], 6.39; 95% confidence interval [CI], 3.7-11.0). This association was stronger than the association between radiographic pneumonia and antibiotic receipt (OR, 3.49; 95% CI, 1.98-6.14). Children prescribed antibiotics were more likely to seek care after discharge than children who were not (OR, 1.85; 95% CI, 1.13-3.05).

CONCLUSIONS

Intention to prescribe antibiotics based on clinical impression was the strongest predictor of antibiotic prescription in our study. Prescribing antibiotics may lead to subsequent medical care after controlling for radiographic pneumonia.

Impact analysis of expanding narrow-spectrum antibiotic use for children with ear, sinus and throat infections

Aim: Estimate the impacts treating acute respiratory tract infections (ARTIs) in children aged 6 months through 12 years with narrow-spectrum antibiotics. Materials & methods: Decision-tree model to estimate children's health, healthcare utilization and costs, and caregiver's time and costs for using narrow-spectrum antibiotics in eligible children with an ARTI, compared with current use of narrow- and broad-spectrum antibiotics. Results: Reduced adverse drug reactions by 35,750 (14%) cases) and 4750 (12%) fewer emergency department visits, 300 (12%) fewer hospitalizations, and 50,500 (10%) avoided outpatient visits. Annual healthcare costs fell by US$120 million (22%). Total societal costs declined by US$131 million (20%). Conclusion: National implementation of narrow-spectrum antibiotics to treat ARTIs in children improves patient outcomes and reduces caregiver burden and annual healthcare costs.

Fluoroquinolone Antibiotics and Tendon Injury in Adolescents

OBJECTIVES

To estimate the association between fluoroquinolone use and tendon injury in adolescents.

METHODS

We conducted an active-comparator, new-user cohort study using population-based claims data from 2000 to 2018. We included adolescents (aged 12-18 years) with an outpatient prescription fill for an oral fluoroquinolone or comparator broad-spectrum antibiotic. The primary outcome was Achilles, quadricep, patellar, or tibial tendon rupture identified by diagnosis and procedure codes. Tendinitis was a secondary outcome. We used weighting to adjust for measured confounding and a negative control outcome to assess residual confounding.

RESULTS

The cohort included 4.4 million adolescents with 7.6 million fills for fluoroquinolone (275 767 fills) or comparator (7 365 684) antibiotics. In the 90 days after the index antibiotic prescription, there were 842 tendon ruptures and 16 750 tendinitis diagnoses (crude rates 0.47 and 9.34 per 1000 person-years, respectively). The weighted 90-day tendon rupture risks were 13.6 per 100 000 fluoroquinolone-treated adolescents and 11.6 per 100 000 comparator-treated adolescents (fluoroquinolone-associated excess risk: 1.9 per 100 000 adolescents; 95% confidence interval -2.6 to 6.4); the corresponding number needed to treat to harm was 52 632. For tendinitis, the weighted 90-day risks were 200.8 per 100 000 fluoroquinolone-treated adolescents and 178.1 per 100 000 comparator-treated adolescents (excess risk: 22.7 per 100 000; 95% confidence interval 4.1 to 41.3); the number needed to treat to harm was 4405.

CONCLUSIONS

The excess risk of tendon rupture associated with fluoroquinolone treatment was extremely small, and these events were rare. The excess risk of tendinitis associated with fluoroquinolone treatment was also small. Other more common potential adverse drug effects may be more important to consider for treatment decision-making, particularly in adolescents without other risk factors for tendon injury.

Effect of Rapid Respiratory Virus Testing on Antibiotic Prescribing Among Children Presenting to the Emergency Department With Acute Respiratory Illness: A Randomized Clinical Trial

IMPORTANCE

There is high usage of antibiotics in the emergency department (ED) for children with acute respiratory illnesses. Studies have reported decreased antibiotic use among inpatients with rapid respiratory pathogen (RRP) testing.

OBJECTIVE

To determine whether RRP testing leads to decreased antibiotic use and health care use among children with influenzalike illness (ILI) in an ED.

DESIGN, SETTING, AND PARTICIPANTS

A randomized clinical trial among children aged 1 month to 18 years presenting to an ED with ILI from December 1, 2018, to November 30, 2019, was conducted. Data were analyzed March 23, 2020, to April 2, 2021. All children received a nasopharyngeal swab for RRP testing and were randomized 1:1 to the intervention group or control group (results not given, routine clinical care). Results were available in 45 minutes. Intention-to-treat analyses and modified intention-to-treat (clinician knows results) analyses were conducted using multivariable Poisson regression.

INTERVENTIONS

Rapid respiratory pathogen test results given to clinicians.

MAIN OUTCOMES AND MEASURES

Antibiotic prescribing was the primary outcome; influenza antiviral prescribing, ED length of stay, hospital admission, and recurrent health care visits were the secondary outcomes.

RESULTS

Among 931 ED visits (intervention group, 452 children group and control group, 456 children after exclusion of those not meeting criteria or protocol violations), a total of 795 RRP test results (85%) were positive. The median age of the children was 2.1 years (interquartile range, 0.9-5.6 years); 509 (56%) were boys. Most children (478 [53%]) were Hispanic, 688 children (76%) received government insurance, and 314 (35%) had a high-risk medical condition. In the intention-to-treat intervention group, children were more likely to receive antibiotics (relative risk [RR], 1.3; 95% CI, 1.0-1.7), with no significant differences in antiviral prescribing, medical visits, and hospitalization. In inverse propensity-weighted modified intention-to-treat analyses, children with test results known were more likely to receive antivirals (RR, 2.6; 95% CI, 1.6-4.5) and be hospitalized (RR, 1.8; 95% CI, 1.4-2.5); there was no significant difference in antibiotic prescribing (RR, 1.1; 95% CI, 0.9-1.4).

CONCLUSIONS AND RELEVANCE

The use of RRP testing in the ED for ILI did not decrease antibiotic prescribing in this randomized clinical trial. There is a limited role for RRP pathogen testing in children in this setting.

Policy Statement: Antibiotic Stewardship in Pediatrics

Antibiotic overuse contributes to antibiotic resistance, which is a threat to public health. Antibiotic stewardship is a practice dedicated to prescribing antibiotics only when necessary and, when antibiotics are considered necessary, promoting the use of the appropriate agent(s), dose, duration, and route of therapy to optimize clinical outcomes while minimizing the unintended consequences of antibiotic use. Because there are differences in common infectious conditions, drug-specific considerations, and the evidence surrounding treatment recommendations (eg, first-line therapy and duration of therapy) between children and adults, this statement provides specific guidance for the pediatric population. This policy statement discusses the rationale for inpatient and outpatient antibiotic stewardship programs (ASPs); essential personnel, infrastructure, and activities required; approaches to evaluating their effectiveness; and gaps in knowledge that require further investigation. Key guidance for both inpatient and outpatient ASPs are provided.

A Learning Collaborative to Improve Antibiotic Prescribing in Primary Care Pediatric Practices

An American Academy of Pediatrics State Chapter organized a 6-month, mostly online quality improvement learning collaborative to improve antibiotic prescribing and patient education for upper respiratory infection (URI) and acute otitis media (AOM). Practices submitted data on quality measures at baseline, monthly, and 4 months post-project. Fifty-three clinicians from 6 independent, private primary care pediatric practices participated. Use of first-line antibiotics for AOM increased from 63.5% at baseline to 80.4% 4 months post-project. Use of safety-net antibiotic prescriptions (SNAP) for AOM increased from 4.5% to 16.9%. Educating patients about management for URI increased from 66.1% to 88.0% and for AOM from 20.4% to 85.6%. Practices maintained high performance for not prescribing antibiotics for URI (94.4% to 96.2%). Leveraging local relationships and national resources, this replicable antibiotic stewardship project engaged independent private practices to improve patient education for URI and AOM and prescribing and use of SNAP for AOM.

Antibiotic allergy as a cause of hospitalization in adults: a hospital-based study in Ukraine

Background:

Antibiotic allergy is an important clinical and social-economical issue.

Objective:

The main objectives of this study were to determine the incidence, causative drugs, and risk groups of antibiotic allergy as a reason for hospitalization. The secondary objective was to evaluate the treatment of antibiotic allergy through the identification of drug related problems (DRPs).

Methods:

This retrospective hospital-based study was carried out in one of Lviv city hospitals (Ukraine) from January 2015 to December 2017. Patients with antibiotic allergy as a cause for hospitalization were included in this study.

Results:

In this study the incidence of antibiotic allergy was 2.0% (95%CI 1.6:2.4) of all admissions to the Unit that provides special medical care for adult inpatients with allergy diseases and allergy reactions. The mean age of patients was 48.5 years (SD=17.0; range 18-83 years) with female predominance (78.2%; 95%CI 68.9:85.2). Antibiotic hypersensitivity reactions manifested as urticaria with angioedema (52.5%; 95%CI 42.3:62.5), urticaria (36.6%; 95%CI 27.8:46.8) or angioedema (10.9%; 95%CI 5.6:18.7). Beta-lactams (48.5%; 95%CI 38.5:58.7), fluoroquinolones (13.9%; 95%CI 7.8%:22.2%) and macrolides (7.9%; 95%CI 3.5:15.0) were specified as the main causative drugs. All patients during hospitalization (a mean of 8.2 days; SD=2.2; range 2-13 days) took at least 3 medicines (a mean of 5.4 medicines per patient; SD=1.2; range 3-12 medicines). The total number of identified DRPs was 400, a mean of 4.0 DRPs per patient (SD=1.8). The most frequently identified type of DRPs was inappropriate route of drug administration (25.0%; 95%CI 20.8:29.5). This was followed by duplicate prescriptions (23.5%; 95%CI 19.4:28.0) and insufficient frequency of drug administration (19.0%; 95%CI 15.3:23.2). Potential drug-drug interactions and inappropriate drug prescriptions each accounted for 16.0% (95% CI 12.6:20.0) of all DRPs. Comparing all above items in 2015, 2016 and 2017 showed no statistically significant changes (p>0.05).

Conclusions:

Antibiotic allergy is a common reason for admissions. The treatment of antibiotic allergy is associated with numerous DRPs. Our results could be useful for development of strategies for improving the safety and quality of pharmacotherapy.

Antibiotic-Associated Adverse Events in Hospitalized Children

BACKGROUND

Antibiotic-associated adverse events (AEs) in hospitalized children have not been comprehensively characterized.

METHODS

We conducted a retrospective observational study of children hospitalized at The Johns Hopkins Hospital receiving ≥24 hours of systemic antibiotics. Consensus regarding antibiotic-associated AE definitions was established by 5 infectious diseases specialists prior to data collection. Two physicians reviewed potential AEs and determined whether they were more likely than not related to antibiotics after comprehensive manual chart review. Inpatient and post-discharge AEs were identified using the Epic Care Everywhere network. AEs evaluated from the initiation of antibiotics until 30 days after antibiotic completion included gastrointestinal, hematologic, hepatobiliary, renal, neurologic, dermatologic, cardiac, myositis, vascular access device-related events, and systemic reactions. Ninety-day AEs included Clostridioides difficile infections, multidrug-resistant organism infections, and clinically significant candidal infections. The impact of AEs was categorized as necessitating additional diagnostic testing, changes in medications, unplanned medical encounters, prolonged or new hospitalizations, or death.

RESULTS

Among 400 antibiotic courses, 21% were complicated by at least one AE and 30% occurred post-discharge. Each additional day of antibiotics was associated with a 7% increased odds of an AE. Of courses complicated by an AE, 66% required further intervention. Hematologic, gastrointestinal, and renal AEs were the most common, accounting for 31%, 15%, and 11% of AEs, respectively. AEs complicated 35%, 35%, 19%, and 18% of courses of piperacillin-tazobactam, tobramycin, ceftazidime, and vancomycin, respectively.

CONCLUSIONS

More than 1 in 5 courses of antibiotics administered to hospitalized children are complicated by AEs. Clinicians should weigh the risk of harm against expected benefit when prescribing antibiotics.

Anthroposophic Medicine: A Short Monograph and Narrative Review-Foundations, Essential Characteristics, Scientific Basis, Safety, Effectiveness and Misconceptions

INTRODUCTION

Anthroposophic medicine is a form of integrative medicine that originated in Europe but is not well known in the US. It is comprehensive and heterogenous in scope and remains provocative and controversial in many academic circles. Assessment of the nature and potential contribution of anthroposophic medicine to whole person care and global health seems appropriate.

METHODS

Because of the heterogenous and multifaceted character of anthroposophic medicine, a narrative review format was chosen. A Health Technology Assessment of anthroposophic medicine in 2006 was reviewed and used as a starting point. A Medline search from 2006 to July 2020 was performed using various search terms and restricted to English. Books, articles, reviews and websites were assessed for clinical relevance and interest to the general reader. Abstracts of German language articles were reviewed when available. Reference lists of articles and the author's personal references were also consulted.

RESULTS

The literature on anthroposophic medicine is vast, providing new ways of thinking, a holistic view of the world, and many integrating concepts useful in medicine. In the last ∼20 years there has been a growing research base and implementation of many anthroposophical concepts in the integrated care of patients. Books and articles relevant to describing the foundations, scientific status, safety, effectiveness and criticisms of anthroposophic medicine are discussed.

DISCUSSION

An objective and comprehensive analysis of anthroposophic medicine finds it provocative, stimulating and potentially fruitful as an integrative system for whole person care, including under-recognized life processes and psychospiritual aspects of human beings. It has a legitimate, new type of scientific status as well as documented safety and effectiveness in some areas of its multimodal approach. Criticisms and controversies of anthroposophic medicine are often a result of lack of familiarity with its methods and approach and/or come from historically fixed ideas of what constitutes legitimate science.

Rurality of Residence and Inappropriate Antibiotic Use for Acute Respiratory Infections Among Young Tennessee Children

Background

Antibiotic use is common for acute respiratory infections (ARIs) in children, but much of this use is inappropriate. Few studies have examined whether rurality of residence is associated with inappropriate antibiotic use. We examined whether rates of ARI-related inappropriate antibiotic use among children vary by rurality of residence.

Methods

We conducted a retrospective cohort study of children aged 2 months-5 years enrolled in Tennessee Medicaid between 2007 and 2017 and diagnosed with ARI in the outpatient setting. Study outcomes included ARI, ARI-related antibiotic use, and ARI-related inappropriate antibiotic use. Multivariable Poisson regression was used to measure associations between rurality of residence, defined by the US Census Bureau, and the rate of study outcomes, while accounting for other factors including demographics and underling comorbidities.

Results

A total of 805 332 children met selection criteria and contributed 1 840 048 person-years (p-y) of observation. Children residing in completely rural, mostly rural, and mostly urban counties contributed 70 369 (4%) p-y, 479 121 (26%) p-y, and 1 290 558 p-y (70%), respectively. Compared with children in mostly urban counties (238 per 1000 p-y), children in mostly rural (450 per 1000 p-y) and completely rural counties (468 per 1000 p-y) had higher rates of inappropriate antibiotic use (adjusted incidence rate ratio [aIRR] = 1.34, 95% confidence interval [CI] = 1.33-1.35 and aIRR = 1.33, 95% CI = 1.32-1.35, respectively).

Conclusions

Inappropriate antibiotic use is common among young children with ARI, with higher rates in rural compared with urban counties. These differences should inform targeted outpatient antibiotic stewardship efforts.

Parenteral Antibiotic Use Among Ambulatory Children in United States Children's Hospital Emergency Departments

Background

Despite increasing recognition of the importance of optimal antibiotic selection and expansion of antimicrobial stewardship activities to ambulatory settings, few studies have examined the frequency of parenteral antibiotic use among ambulatory children. We assessed the prevalence and patterns of parenteral antibiotic administration among ambulatory children in pediatric emergency departments (EDs).

Methods

We conducted a cross-sectional assessment of parenteral antibiotic use among ambulatory children aged 0–18 years in 49 US children’s hospital EDs in 2018. We assessed the prevalence rates of parenteral antibiotic use and stratified these by patient-, clinic-, and hospital-level characteristics. We also assessed the prevalence of use of specific antibiotics by age and diagnosis category. Among encounters associated with an infection diagnosis, we identified factors associated with parenteral antibiotic use using multivariable logistic regression.

Results

Among 3452011 ambulatory ED encounters in 2018, parenteral antibiotics were administered in 62648 (1.8%). The highest proportion of parenteral antibiotic use occurred in the 15–18-year age group (3.3%) and among encounters in children with complex chronic conditions (8.9%) and with primary diagnoses of neoplasms (36%). Ceftriaxone was the most commonly administered parenteral antibiotic (61%). In multivariable analysis, several factors including age ≤2 months, White race, private insurance, complex chronic conditions, digestive and genitourinary system diseases, and encounters attributed to emergency medicine providers were significantly associated with higher odds of parenteral antibiotic use.

Conclusions

This study demonstrates substantial variability in the frequency of parenteral antibiotic administration by age and diagnosis in the ambulatory ED setting and highlights potential opportunities to target stewardship activities.

Publishing trends in the field of urgent care medicine from 2000 to 2020: A bibliometric analysis

BACKGROUND

With a steady rise in the number of urgent care centers in the United States and the establishment of urgent care medicine as a specialty, research in the field is likely to emerge.

OBJECTIVES

To perform a bibliometric analysis of published studies in the field of urgent care medicine over the past two decades.

METHODS

A comprehensive literature review was conducted, including original and review articles pertaining to urgent care medicine published 2000-2020. Data abstracted from each article included publication year, journal, research study design, study population, clinical relevance (clinical or non-clinical), and study topics.

RESULTS

A total of 144 publications from 94 peer-reviewed journals were analyzed. There has been a steady increase in the annual number of publications from 2010 to 2019. The most common study designs were retrospective (55.5%), study specific (24.3%), prospective (15.3%), and quality improvement (4.9%). Adults were the most frequently identified study population (33.3%), followed by pediatrics (18%), and both adults and pediatrics (16.7%). Publications were categorized as clinical (48.6%) and non-clinical (51.4%). The most common research topics were urgent care utilization [n = 34, 23.6%; especially effectiveness (n = 9) and disease based (n = 7)], diagnostic testing [(n = 20, 13.9%; especially HIV (n = 7) and sexually transmitted infections (n = 6)], and antibiotic stewardship (n = 17, 11.8%).

CONCLUSION

Based on our sample, published research in the field of urgent care medicine has evolved. By describing current trends, we hope that clinicians and researchers continue to advance the field by developing high quality research, including prospective, multi-institutional/center studies involving both clinical and non-clinical topics.

Mahaenggamseok-tang, a herbal medicine, for lower respiratory tract infections in pediatric patients: A protocol for systematic review and meta-analysis

BACKGROUND

The aim of this study is to assess the clinical evidence for or against Mahaenggamseok-tang (MHGT) as a treatment for lower respiratory tract infections (LRTIs) in pediatric patients.

METHOD

This systematic review will include randomized clinical trials (RCTs) of MHGT, as a treatment for LRTIs, compared with other therapies such as placebo and western medicine. The search terms will be selected according to the medical subject heading. We will search the following databases for systematic reviews from 2000 to Feb 2020: 5 English databases (The Cochrane Database of Systematic reviews, MEDLINE, Excerpta Medica dataBASE, Allied and Complementary Medicine Database, and Cumulative Index to Nursing and Allied Health Literature), 1 Chinese database, 5 Korean databases (Oriental Medicine Advanced Searching Integrated System, DataBase Periodical Information Academic (DBPIA), Research Information Service System, Korean Studies Information Service System, and National Digital Science Library), and 1 Japanese database (J-Stage). All RCTs of decoctions or alternate forms of MHGT will be included. We will search for all parallel or crossover RCTs without language restrictions. The methodological quality of the RCTs will be assessed using Cochrane risk of bias. Furthermore, the studies will be limited to those performed in children under 16 years of age.

RESULTS AND CONCLUSIONS

Our systematic review and meta-analysis will provide evidence for MHGT as a treatment for LRTI. The findings can help practitioners and patients recognize more effective and safer therapeutic methods.

A qualitative study examining pediatric clinicians' perceptions of delayed vaccine schedules

OBJECTIVE

To explore pediatric clinicians' attitudes, beliefs, and perceived social norms about the impact of delayed vaccine schedules on the clinical management of their patients.

METHODS

We conducted 30 semi-structured qualitative interviews with academic (Infectious Diseases, Emergency Medicine) and community pediatric clinicians (General Pediatrics) to explore clinicians' perspectives on how delayed schedules influence their clinical management of patients. The interview guide was based on the Theory of Planned Behavior. We analyzed interview transcripts using both an inductive and deductive thematic approach.

RESULTS

The pediatric clinicians in our study overwhelmingly supported the recommended schedule, sought guidance on approaches to navigating conversations with vaccine hesitant families, and desired more evidence to effectively promote on-time vaccination. Clinicians described how delayed schedules have consequences for sick children (e.g., increased antibiotics, laboratory tests, emergency department visits) and healthy children (e.g., increased vaccine visits, out-of-pocket costs, fears among children receiving frequent shots). Clinicians stated that delayed schedules also negatively impact pediatric practices (e.g., increased time counseling patients, staff burden, clogged clinic space, unpredictable vaccine utilization, costs).

CONCLUSIONS

Pediatric clinicians perceive that delayed vaccine schedules negatively affect patients, pediatric practices, the healthcare system, and society. Future research should quantify the consequences of delayed schedules and identify strategies that promote vaccine adherence. Results from future studies can better support clinician-parent conversations about vaccine hesitancy, guide decision-makers about practice-level approaches to vaccine schedules, and advise payors and policymakers regarding vaccine-related policies.

Improving Antibiotic Prescribing for Pediatric Urinary Tract Infections in Outpatient Settings

OBJECTIVES

To determine if a multicomponent intervention was associated with increased use of first-line antibiotics (cephalexin or sulfamethoxazole and trimethoprim) among children with uncomplicated urinary tract infections (UTIs) in outpatient settings.

METHODS

The study was conducted at Kaiser Permanente Colorado, a large health care organization with ∼127 000 members <18 years of age. After conducting a gap analysis, an intervention was developed to target key drivers of antibiotic prescribing for pediatric UTIs. Intervention activities included development of new local clinical guidelines, a live case-based educational session, pre- and postsession e-mailed knowledge assessments, and a new UTI-specific order set within the electronic health record. Most activities were implemented on April 26, 2017. The study design was an interrupted time series comparing antibiotic prescribing for UTIs before versus after the implementation date. Infants <60 days old and children with complex urologic or neurologic conditions were excluded.

RESULTS

During January 2014 to September 2018, 2142 incident outpatient UTIs were identified (1636 preintervention and 506 postintervention). Pyelonephritis was diagnosed for 7.6% of cases. Adjusted for clustering of UTIs within clinicians, the proportion of UTIs treated with first-line antibiotics increased from 43.4% preintervention to 62.4% postintervention (P < .0001). The use of cephalexin (first-line, narrow spectrum) increased from 28.9% preintervention to 53.0% postintervention (P < .0001). The use of cefixime (second-line, broad spectrum) decreased from 17.3% preintervention to 2.6% postintervention (P < .0001). Changes in prescribing practices persisted through the end of the study period.

CONCLUSIONS

A multicomponent intervention with educational and process-improvement elements was associated with a sustained change in antibiotic prescribing for uncomplicated pediatric UTIs.

Antibiotic Use and Outcomes in Children in the Emergency Department With Suspected Pneumonia

BACKGROUND AND OBJECTIVES

Antibiotic therapy is often prescribed for suspected community-acquired pneumonia (CAP) in children despite a lack of knowledge of causative pathogen. Our objective in this study was to investigate the association between antibiotic prescription and treatment failure in children with suspected CAP who are discharged from the hospital emergency department (ED).

METHODS

We performed a prospective cohort study of children (ages 3 months-18 years) who were discharged from the ED with suspected CAP. The primary exposure was antibiotic receipt or prescription. The primary outcome was treatment failure (ie, hospitalization after being discharged from the ED, return visit with antibiotic initiation or change, or antibiotic change within 7-15 days from the ED visit). The secondary outcomes included parent-reported quality-of-life measures. Propensity score matching was used to limit potential bias attributable to treatment selection between children who did and did not receive an antibiotic prescription.

RESULTS

Of 337 eligible children, 294 were matched on the basis of propensity score. There was no statistical difference in treatment failure between children who received antibiotics and those who did not (odds ratio 1.0; 95% confidence interval 0.45-2.2). There was no difference in the proportion of children with return visits with hospitalization (3.4% with antibiotics versus 3.4% without), initiation and/or change of antibiotics (4.8% vs 6.1%), or parent-reported quality-of-life measures.

CONCLUSIONS

Among children with suspected CAP, the outcomes were not statistically different between those who did and did not receive an antibiotic prescription.

Diagnosis of Urinary Tract Infection in the Neuropathic Bladder: Changing the Paradigm to Include the Microbiome

Bacteriuria, a non-specific term that refers to the presence of bacteria in the urine, is common in people with neuropathic bladders. However, accurately determining when bacteriuria represents a urinary tract infection (UTI) as opposed to asymptomatic bacteriuria is difficult. There is currently no widely accepted definition of what constitutes a UTI in people with neuropathic bladders. As a result, there is significant variation in care, which likely leads to unnecessary use of antibiotics for bacteriuria. To improve the clinical management of people with neuropathic bladders, it is important to be able to accurately diagnose and treat UTIs. In this article, we review the difficulties associated with accurately diagnosing UTIs and then review proposed definitions. Finally, we discuss the emerging literature of the urinary microbiome and how this may assist in accurately diagnosing UTIs in people with neuropathic bladders.

Formula feeding increases the risk of antibiotic prescriptions in children up to 2 years: results from a cohort study

Association between the use of infant formula and risks for infants' health is seldom studied in western countries. We set up a historical cohort based on record linkage analysis, combining the data from administrative databases providing individual data. Infants receiving the second dose of pediatric immunization between 2015 and 2017 were included. The main outcome measure was antibiotic prescriptions from enrolment up to 24 months of age, by infant feeding category at enrolment. The extended Cox regression technique was used to account for recurrent events. The infants' cohort included 40,258 5-month-old infants; during the study period, 60,932 antibiotic prescriptions were filled. Compared with infants fully breastfed, children fed with both maternal milk and formula received 106 more antibiotic prescriptions per 1000 children/year, whereas infants receiving formula only had 138 excess prescriptions per 1000 children/year. The association with infant feeding was statistically significant and remained unchanged after adjustment for common confounders (adjusted hazard ratio, HR, for complementary feeding vs full breastfeeding 1.09; 95%CI 1.05 to 1.12; formula only versus full breastfeeding adj. HR 1.12; 95%CI 1.08 to 1.16).Conclusion: In our cohort, we observed a positive association between infant formula use considered a proxy of infections antibiotic prescription rate, considered a proxy of infections. The association followed a gradient.What is Known:• Formula feeding is associated with increased morbidity and mortality even in western countries, but still, it is common.• Information on formula are seldom unbiased; thus, public perception of risks is distorted.What is New:• In a large Italian cohort of infants, formula feeding at 5 months of age results to be associated with an increased rate of antibiotic prescription (considered to be a proxy of infection) up to 24 months of age: the association follows a dose-response relationship.• Record linkage analysis using administrative databases provides useful information at a limited cost.
