Variation in Outpatient Antibiotic Dispensing for Respiratory Infections in Children by Clinician Specialty and Treatment Setting

Evaluation of FebriDx® for the management of children with acute febrile respiratory infection

INTRODUCTION

Acute respiratory infections (ARI) are a common cause of inappropriate antibiotic prescription (ATB) in pediatrics. FebriDx® is a rapid diagnostic test that differentiates between viral and bacterial infections. The objective is to analyse the impact of FebriDx® on ATB prescription when managing febrile ARI.

METHODS

Prospective study carried out in patients aged 1-<18 years with febrile ARI in the emergency department. FebriDx® was performed and the impact on management was evaluated at follow-up.

RESULTS

A total of 216 patients were included. Clinical assessment and FebriDx® result coincided coincided in 174 (80.5%) cases. A modification of the initial therapeutic plan was made in 22 (52.4%) of the 42 discordant ones (10.2% of the overall patients). In pneumonia the impact was 34.5%; in all cases it involved not prescribing ATB.

CONCLUSIONS

FebriDx® could be a useful tool in the management of pediatric patients with febrile ARI to optimize ATB prescription.

Factors contributing to the variation in antibiotic prescribing among primary health care physicians: a systematic review

BACKGROUND

Antibiotic resistance is growing globally. The practice of health professionals when prescribing antibiotics in primary health care settings significantly impacts antibiotic resistance. Antibiotic prescription is a complex process influenced by various internal and external factors. This systematic review aims to summarize the available evidence regarding factors contributing to the variation in antibiotic prescribing among physicians in primary healthcare settings.

METHODS

This systematic review was conducted based on PRISMA guidelines. We included qualitative, quantitative and mixed methods studies that examined factors influencing prescription practice and variability among primary healthcare physicians. We excluded editorials, opinions, systematic reviews and studies published in languages other than English. We searched studies from electronic databases: PubMed, ProQuest Health and Medicine, Web Science, and Scopus. The quality of the included studies was appraised using the Mixed Methods Appraisal Tool (Version 2018). Narrative synthesis was employed to synthesize the result and incorporate quantitative studies.

RESULTS

Of the 1816 identified studies, 49 studies spanning 2000-2023 were eligible for review. The factors influencing antibiotic prescription practice and variability were grouped into physician-related, patient-related, and healthcare system-related factors. Clinical guidelines, previous patient experience, physician experience, colleagues' prescribing practice, pharmaceutical pressure, time pressure, and financial considerations were found to be influencing factors of antibiotic prescribing practice. In addition, individual practice patterns, practice volume, and relationship with patients were also other factors for the variability of antibiotic prescription, especially for intra-physician prescription variability.

CONCLUSION

Antibiotic prescription practice in primary health care is a complex practice, influenced by a combination of different factors and this may account for the variation. To address the factors that influence the variability of antibiotic prescription (intra- and inter-physician), interventions should aim to reduce diagnostic uncertainty and provide continuous medical education and training to promote patient-centred care.

Pediatric Antibiotic Prescribing and Utilization Practices for RTIs at Private Urgent Care Centers

Data on pediatric antibiotic prescribing and utilization practices at urgent care centers (UCC) remain limited. In this study, an electronic medical record-based review of UCC encounters for respiratory tract infections (RTI) of patients belonging to one mid-sized pediatric practice was performed. Antibiotic prescribing and guideline adherence were compared between UCCs that were staffed exclusively by pediatric-trained providers to those staffed otherwise. Of a total of 457 RTI visits, 330 (72%) occurred at the pediatric UCC. Across all bacterial RTIs, 82% of encounters at the pediatric UCC were guideline-adherent versus 59% at nonpediatric UCCs (P < .001). At nonpediatric UCCs, pharyngitis was the most common RTI encounter diagnosis (40%), and full streptococcal management guideline adherence was 41%. While 93% of RTI-UCC encounters for <2 years were at pediatric UCCs, the majority of children >10 presented to nonpediatric UCCs. RTI guideline education to UCCs should be a focus of ambulatory stewardship efforts.

A Mixed-Methods Assessment of Coronavirus Disease of 2019-Era Telehealth Acute Care Visits in the Medical Home

OBJECTIVES

To compare acute care virtual visits with in-person visits with respect to equity of access, markers of quality and safety, and parent and provider experience, before and during the coronavirus disease 2019 pandemic.

STUDY DESIGN

We compared patient demographics, antimicrobial prescribing rates, emergency department (ED) use, and patient-experience scores for virtual visits and in-person care at 2 academic pediatric primary care practices using χ² testing and interrupted time series analyses. Parent and provider focus groups explored themes related to virtual visit experience and acceptability.

RESULTS

We compared virtual acute care visits conducted in March 2020-February 2021 (n = 8868) with in-person acute care visits conducted in February 2019-March 2020 (n = 24 120) and March 2020-February 2021 (n = 6054). There were small differences in patient race/ethnicity across the different cohorts (P < .01). Virtual visits were associated with a 9.6% (-11.5%, -7.8%, P < .001) decrease in all antibiotic prescribing and a 13.2% (-22.1%, -4.4%, P < .01) decrease in antibiotic prescribing for acute respiratory tract infections. Unanticipated visits to the ED did not significantly differ among visit types. Patient experience scores were significantly greater (P < .05) for virtual acute care in overall rating of care and likelihood to recommend. Focus group themes included safety, distractibility, convenience, treatment, and technology. Providers were broadly accepting of virtual care while parental views were more mixed.

CONCLUSIONS

Telehealth acute care visits may not have negative effects on quality and safety, as measured by antimicrobial prescribing and unanticipated ED visit rates. Efforts to increase parental acceptance and avoid creating disparities in access to virtual care will be essential to continued success of telehealth acute care visits.

Look-Back and Look-Forward Durations and the Apparent Appropriateness of Ambulatory Antibiotic Prescribing

Ambulatory antibiotic stewards, researchers, and performance measurement programs choose different durations to associate diagnoses with antibiotic prescriptions. We assessed how the apparent appropriateness of antibiotic prescribing changes when using different look-back and look-forward periods. Examining durations of 0 days (same-day), -3 days, -7 days, -30 days, ±3 days, ±7 days, and ±30 days, we classified all ambulatory antibiotic prescriptions in the electronic health record of an integrated health care system from 2016 to 2019 (714,057 prescriptions to 348,739 patients by 2391 clinicians) as chronic, appropriate, potentially appropriate, inappropriate, or not associated with any diagnosis. Overall, 16% percent of all prescriptions were classified as chronic infection related. Using only same-day diagnoses, appropriate, potentially appropriate, inappropriate, and not-associated antibiotics, accounted for 14%, 36%, 22%, and 11% of prescriptions, respectively. As the duration of association increased, the proportion of appropriate antibiotics stayed the same (range, 14% to 18%), potentially appropriate antibiotics increased (e.g., 43% for -30 days), inappropriate stayed the same (range, 22% to 24%), and not-associated antibiotics decreased (e.g., 2% for -30 days). Using the longest look-back-and-forward duration (±30 days), appropriate, potentially appropriate, inappropriate, and not-associated antibiotics, accounted for 18%, 44%, 20%, and 2% of prescriptions, respectively. Ambulatory programs and studies focused on appropriate or inappropriate antibiotic prescribing can reasonably use a short duration of association between an antibiotic prescription and diagnosis codes. Programs and studies focused on potentially appropriate antibiotic prescribing might consider examining longer durations.

Do Financial Incentives Affect Utilization for Chronically Ill Medicare Beneficiaries?

OBJECTIVE

The objective of this study was to examine the price sensitivity for provider visits among Medicare Advantage beneficiaries.

DATA SOURCES

We used Medicare Advantage encounter data from 2014 to 2017 accessed as part of an evaluation for the Center for Medicare & Medicaid Innovation.

STUDY DESIGN

We analyzed the effect of cost-sharing on the utilization of 2 outcome categories: number of visits (specialist and primary care) and the probability of any visit (specialist and primary care). Our main independent variable was the size of the copayment for the visit, which we regressed on the outcomes with several beneficiary-level and plan-level control variables.

DATA COLLECTION/EXTRACTION METHODS

We included beneficiaries with at least 1 of 4 specific chronic conditions and matched comparison beneficiaries. We did not require beneficiaries to be continuously enrolled from 2014 to 2017, but we required a full year of data for each year they were observed. This resulted in 371,140 beneficiary-year observations.

PRINCIPAL FINDINGS

Copay reductions were associated with increases in utilization, although the changes were small, with elasticities <-0.2. We also found evidence of substitution effects between primary care provider (PCP) and specialist visits, particularly cardiology and endocrinology. When PCP copays declined, visits to these specialists also declined.

CONCLUSIONS

We find that individuals with chronic conditions respond to changes in copays, although these responses are small. Reductions in PCP copays lead to reduced use of some specialists, suggesting that lowering PCP copays could be an effective way to reduce the use of specialist care, a desirable outcome if specialists are overused.

Pediatric Primary Health Care: The Central Role of Pediatricians in Maintaining Children's Health in Evolving Health Care Models

Pediatric primary health care (PPHC) is of principal importance to the health and development of all children, helping them reach their true potential. Pediatricians, as the clinicians most intensively trained and experienced in child health, are the natural leaders of PPHC within the context of the medical home. Given the rapidly evolving models of pediatric health care delivery, including the explosion of telehealth in the wake of the COVID-19 pandemic, pediatricians, together with their representative national organizations such as the American Academy of Pediatrics (AAP), are the most capable clinicians to guide policy innovations on both the local and national stage.

Paediatric Antimicrobial Stewardship for Respiratory Infections in the Emergency Setting: A Systematic Review

Antimicrobial resistance occurs due to the propensity of microbial pathogens to develop resistance to antibiotics over time. Antimicrobial stewardship programs (ASPs) have been developed in response to this growing crisis, to limit unnecessary antibiotic prescription through initiatives such as education-based seminars, prescribing guidelines, and rapid respiratory pathogen (RRP) testing. Paediatric patients who present to the emergency setting with respiratory symptoms are a particularly high-risk population susceptible to inappropriate antibiotic prescribing behaviours and are therefore an ideal cohort for focused ASPs. The purpose of this systematic review was to assess the efficacy and safety of ASPs in this clinical context. A systematic search of PubMed, Medline, EMBASE and the Cochrane Database of Systematic Reviews was conducted to review the current evidence. Thirteen studies were included in the review and these studies assessed a range of stewardship interventions and outcome measures. Overall, ASPs reduced the rates of antibiotic prescription, increased the prescription of narrow-spectrum antibiotics, and shortened the duration of antibiotic therapy. Multimodal interventions that were education-based and those that used RRP testing were found to be the most effective. Whilst we found strong evidence that ASPs are effective in reducing antibiotic prescribing, further studies are required to assess whether they translate to equivalent clinical outcomes.

Antibiotic Prescribing for Acute Respiratory Tract Infections During Telemedicine Visits Within a Pediatric Primary Care Network

OBJECTIVE

Regulatory and payment changes associated with COVID-19 facilitated wide-spread use of telehealth within pediatric primary care starting in March 2020. Given prior quality concerns about antibiotic management for children during telemedicine visits outside of primary care, we sought to examine acute respiratory tract infection (ARTI) visit volume and antibiotic management for children via telemedicine integrated within pediatric primary care.

METHODS

Using electronic health record data from 47 practices within a large pediatric primary care network, we identified visits for ARTI from April to September 2020. For these visits, we categorized antibiotic management consistent with clinical guidelines as guideline concordant. We compared telemedicine and in-person visit guideline-concordant antibiotic management, diagnoses, and antibiotic prescribing using chi-square tests and examined trends over time using descriptive statistics. Antibiotic stewardship during the study period included learning collaborative videoconferences and sharing of clinic and clinician-level metrics through an interactive dashboard.

RESULTS

During the 6-month period, 8332 ARTI visits were identified, with 3003 (36%) via telemedicine. Guideline-concordant antibiotic management occurred in 92.5% of telemedicine visits compared to 90.7% of in-person office visits (P = .004). Telemedicine ARTI visits receiving diagnoses of acute otitis media or streptococcal pharyngitis declined from peak of 52% (May) to 7% (September). Guideline-concordant antibiotic management of sinusitis and viral ARTI during telemedicine visits increased from 88% (April) to 97% (September).

CONCLUSION

With active antibiotic stewardship, pediatricians practicing within certified medical homes consistently delivered highly guideline-concordant care for ARTIs to their patient population via telemedicine integrated into primary care.

Community antibiotic prescribing for children in France from 2015 to 2017: a cross-sectional national study

OBJECTIVES

To assess recent community antibiotic prescribing for French children and identify areas of potential improvement.

METHODS

We analysed 221 768 paediatric (<15 years) visits in a national sample of 680 French GPs and 70 community paediatricians (IQVIA's EPPM database), from March 2015 to February 2017, excluding well-child visits. We calculated antibiotic prescription rates per 100 visits, separately for GPs and paediatricians. For respiratory tract infections (RTIs), we described broad-spectrum antibiotic use and duration of treatment. We used Poisson regression to identify factors associated with antibiotic prescribing.

RESULTS

GPs prescribed more antibiotics than paediatricians [prescription rate 26.1 (95% CI 25.9-26.3) versus 21.6 (95% CI 21.0-22.2) per 100 visits, respectively; P < 0.0001]. RTIs accounted for more than 80% of antibiotic prescriptions, with presumed viral RTIs being responsible for 40.8% and 23.6% of all antibiotic prescriptions by GPs and paediatricians, respectively. For RTIs, antibiotic prescription rates per 100 visits were: otitis, 68.1 and 79.8; pharyngitis, 67.3 and 53.3; sinusitis, 67.9 and 77.3; pneumonia, 80.0 and 99.2; bronchitis, 65.2 and 47.3; common cold, 21.7 and 11.6; bronchiolitis 31.6 and 20.1; and other presumed viral RTIs, 24.1 and 11.0, for GPs and paediatricians, respectively. For RTIs, GPs prescribed more broad-spectrum antibiotics [49.8% (95% CI 49.3-50.3) versus 35.6% (95% CI 34.1-37.1), P < 0.0001] and antibiotic courses of similar duration (P = 0.21). After adjustment for diagnosis, antibiotic prescription rates were not associated with season and patient age, but were significantly higher among GPs aged ≥50 years.

CONCLUSIONS

Future antibiotic stewardship campaigns should target presumed viral RTIs, broad-spectrum antibiotic use and GPs aged ≥50 years.

Unnecessary Antibiotic Prescribing in US Ambulatory Care Settings, 2010-2015

The proportion of antibiotic prescriptions prescribed in US physician offices and emergency departments that were unnecessary decreased slightly, from 30% in 2010-2011 to 28% in 2014-2015. However, a greater decrease occurred in children: 32% in 2010-2011 to 19% in 2014-2015. Unnecessary prescribing in adults did not change during this period.

Antibiotic prescriptions for children younger than 5 years with acute upper respiratory infections in China: a retrospective nationwide claims database study

Background

In China, there were few studies to estimate antibiotic use for children with upper respiratory infections at the national level. The aim of this study was to describe the antibiotic prescribing practice for children aged < 5 years old with upper respiratory infections (URIs) using a nationwide claims database.

Methods

This was a retrospective cross-sectional study using a sampled database from the China Health Insurance Research Association (CHIRA). Study subjects included children younger than 5 years with outpatient visits in 2015 that resulted in a diagnosis of a upper respiratory infection. We calculated the percentage of visits who received antibiotics, the proportion of injection formulations, the percentage of combined antibiotics and the proportion of each antibiotic class. The patterns of antibiotic prescription were also described by medical institution type, city level and geographical region.

Results

Among the 92,821 visits, 27.1% were prescribed antibiotics, of which 27.0% received injection formulations. The rate of antibiotic prescribing varied by age group (P < 0.001), with the lowest (16.0%) in infants and the highest in patients at age 3 to < 4 years (29.9%) and age 4 to < 5 years (32.5%). The Midwestern region, underdeveloped cities and low-level hospitals represented relatively higher rates of prescribing antibiotics (P < 0.001) and higher proportions of injection dosage forms (P < 0.001). The most 3 common antibiotic classes prescribed of all visits with antibiotic prescriptions were the third-generation cephalosporins (34.9%), macrolides (24.3%), and the second-generation cephalosporins (23.3%).

Conclusions

In mainland China, the overall rate of antibacterial prescribing and the proportion of injection formulations prescribed in children under 5 years with URIs were at a low level, but still higher in underdeveloped regions and cities. Moreover, the overuse of the second and third generation cephalosporins, macrolides, remains a serious issue. Further efforts should be focused on reducing those non-first-line antibiotic prescribing and narrowing the gaps among regions and cities.

Antibiotic stewardship in direct-to-consumer telemedicine consultations leads to high adherence to best practice guidelines and a low prescription rate

OBJECTIVE

To analyze the antibiotic prescription rate in low-risk patients evaluated at a telemedicine program that adopts antibiotic stewardship protocols.

METHODS

Adult patients who accessed a single direct-to-consumer telemedicine center (Jan/2019-Feb/2020) were retrospectively enrolled. Diseases amenable to antimicrobial treatment were classified under five diagnostic groups: upper respiratory tract infection (URI), acute pharyngotonsillitis (PT), acute sinusitis (AS), urinary tract infection (UTI), and acute diarrhea (AD). Physicians were trained on and advised to strictly follow the current guideline recommendations supported by institutional antibiotic stewardship protocols, readily available online during consultations. We analyzed the antibiotic prescription rate among patients, referral rate, and antibiotic class through descriptive statistics.

RESULTS

A total of 2328 patients were included in the study. A total of 2085 (89·6%) patients were discharged with usual recommendations, medication (if needed), and instructions about red flags, while 243 (10·4%) were referred to a face-to-face consultation. Among the discharged patients, the antibiotic prescription rates by the diagnostic group were URI - 2·5%, PT - 35·0%, AS - 51·8%, UTI - 91.6%, and AD - 1·6%. In most cases, prescribed antibiotics were in line with institutional stewardship protocols.

CONCLUSIONS

Low prescription rate of antibiotics can be achieved using antibiotic stewardship protocols at direct-to-consumer telemedicine consultations, showing high adherence to international guidelines. These results reinforce telemedicine as a cost-effective and safe strategy for the initial assessment of acute non-urgent symptoms.

Characteristics of prescriptions and costs for acute upper respiratory tract infections in Chinese outpatient pediatric patients: a nationwide cross-sectional study

BACKGROUND

To understand the characteristics of prescriptions and costs in pediatric patients with acute upper respiratory infections (AURI) is important for the regulation of outpatient care and reimbursement policy. This study aims to provide evidence on these issues that was in short supply.

METHODS

We conducted a retrospective cross-sectional study based on data from National Engineering Laboratory of Application Technology in Medical Big Data. All outpatient pediatric patients aged 0-14 years with an uncomplicated AURI from 1 January 2015 to 31 December 2017 in 138 hospitals across the country were included. We reported characteristics of patients, the average number of medications prescribed per encounter, the categories of medication used and their percentages, the cost per visit and prescription costs of drugs. For these measurements, discrepancies among diverse groups of age, regions, insurance types, and AURI categories were compared. Kruskal-Wallis nonparametric test and Student-Newman-Keuls test were performed to identify differences among subgroups. A multinomial logistic regression was conducted to examine the independent effects of those factors on the prescribing behavior.

RESULTS

A total of 1,002,687 clinical records with 2,682,118 prescriptions were collected and analyzed. The average number of drugs prescribed per encounter was 2.8. The most frequently prescribed medication was Chinese traditional patent medicines (CTPM) (36.5% of overall prescriptions) followed by antibiotics (18.1%). It showed a preference of CPTM over conventional medicines. The median cost per visit was 17.91 USD. The median drug cost per visit was 13.84 USD. The expenditures of antibiotics and CTPM per visit (6.05 USD and 5.87 USD) were among the three highest categories of drugs. The percentage of out-of-pocket patients reached 65.9%. Disparities were showed among subgroups of different ages, regions, and insurance types.

CONCLUSIONS

The high volume of CPTM usage is the typical feature in outpatient care of AURI pediatric patients in China. The rational and cost-effective use of CPTM and antibiotics still faces challenges. The reimbursement for child AURI cases needs to be enhanced.

Unnecessary antibiotic prescribing in pediatric ambulatory care visits for bronchitis and bronchiolitis in the United States, 2006-2015

Antibiotics are not indicated for the treatment of bronchitis and bronchiolitis. Using a nationally representative database from 2006-2015, we found that antibiotics were prescribed in 58% of outpatient visits for bronchitis and bronchiolitis in children, serving as a possible baseline for the expanded HEDIS 2020 measure regarding antibiotic prescribing for bronchitis.

Variation in antibiotic prescription rates in febrile children presenting to emergency departments across Europe (MOFICHE): A multicentre observational study

BACKGROUND

The prescription rate of antibiotics is high for febrile children visiting the emergency department (ED), contributing to antimicrobial resistance. Large studies at European EDs covering diversity in antibiotic and broad-spectrum prescriptions in all febrile children are lacking. A better understanding of variability in antibiotic prescriptions in EDs and its relation with viral or bacterial disease is essential for the development and implementation of interventions to optimise antibiotic use. As part of the PERFORM (Personalised Risk assessment in Febrile illness to Optimise Real-life Management across the European Union) project, the MOFICHE (Management and Outcome of Fever in Children in Europe) study aims to investigate variation and appropriateness of antibiotic prescription in febrile children visiting EDs in Europe.

METHODS AND FINDINGS

Between January 2017 and April 2018, data were prospectively collected on febrile children aged 0-18 years presenting to 12 EDs in 8 European countries (Austria, Germany, Greece, Latvia, the Netherlands [n = 3], Spain, Slovenia, United Kingdom [n = 3]). These EDs were based in university hospitals (n = 9) or large teaching hospitals (n = 3). Main outcomes were (1) antibiotic prescription rate; (2) the proportion of antibiotics that were broad-spectrum antibiotics; (3) the proportion of antibiotics of appropriate indication (presumed bacterial), inappropriate indication (presumed viral), or inconclusive indication (unknown bacterial/viral or other); (4) the proportion of oral antibiotics of inappropriate duration; and (5) the proportion of antibiotics that were guideline-concordant in uncomplicated urinary and upper and lower respiratory tract infections (RTIs). We determined variation of antibiotic prescription and broad-spectrum prescription by calculating standardised prescription rates using multilevel logistic regression and adjusted for general characteristics (e.g., age, sex, comorbidity, referral), disease severity (e.g., triage level, fever duration, presence of alarming signs), use and result of diagnostics, and focus and cause of infection. In this analysis of 35,650 children (median age 2.8 years, 55% male), overall antibiotic prescription rate was 31.9% (range across EDs: 22.4%-41.6%), and among those prescriptions, the broad-spectrum antibiotic prescription rate was 52.1% (range across EDs: 33.0%-90.3%). After standardisation, differences in antibiotic prescriptions ranged from 0.8 to 1.4, and the ratio between broad-spectrum and narrow-spectrum prescriptions ranged from 0.7 to 1.8 across EDs. Standardised antibiotic prescription rates varied for presumed bacterial infections (0.9 to 1.1), presumed viral infections (0.1 to 3.3), and infections of unknown cause (0.1 to 1.8). In all febrile children, antibiotic prescriptions were appropriate in 65.0% of prescriptions, inappropriate in 12.5% (range across EDs: 0.6%-29.3%), and inconclusive in 22.5% (range across EDs: 0.4%-60.8%). Prescriptions were of inappropriate duration in 20% of oral prescriptions (range across EDs: 4.4%-59.0%). Oral prescriptions were not concordant with the local guideline in 22.3% (range across EDs: 11.8%-47.3%) of prescriptions in uncomplicated RTIs and in 45.1% (range across EDs: 11.1%-100%) of prescriptions in uncomplicated urinary tract infections. A limitation of our study is that the included EDs are not representative of all febrile children attending EDs in that country.

CONCLUSIONS

In this study, we observed wide variation between European EDs in prescriptions of antibiotics and broad-spectrum antibiotics in febrile children. Overall, one-third of prescriptions were inappropriate or inconclusive, with marked variation between EDs. Until better diagnostics are available to accurately differentiate between bacterial and viral aetiologies, implementation of antimicrobial stewardship guidelines across Europe is necessary to limit antimicrobial resistance.

Antibiotic Prescribing Patterns for Acute Otitis Media for Children 2 Years and Older

OBJECTIVE

To determine the frequency that non-first-line antibiotics, safety-net antibiotic prescriptions (SNAPS), and longer than recommended durations of antibiotics were prescribed for children ≥2 years of age with acute otitis media and examine patient and system level factors that contributed to these outcomes.

STUDY DESIGN

Children age ≥2 years with acute otitis media seen at Denver Health Medical Center outpatient locations from January to December 2018 were included. The percentages of patients who received first-line antibiotics, SNAPs, and recommended durations of antibiotics were determined. Factors associated with non-first-line and longer than recommended antibiotic durations were evaluated using multivariate logistic regression modeling.

RESULTS

Of the 1025 visits evaluated, 98.0% were prescribed an antibiotic; only 4.5% of antibiotics were SNAPs. Non-first-line antibiotics were prescribed to 18.8% of patients. Most antibiotic durations (94.1%) were longer than the institution recommended 5 days and 54.3% were ≥10 days. Private insurance was associated with non-first-line antibiotics (aOR, 1.89; 95% CI, 1; 14-3.14, P = .01). Patients who were younger (2-5 years; aOR 2.01; 95% CI, 1.32-3.05; P < .001) or seen in emergency/urgent care sites (aOR, 1.73; 95% CI, 1.26-2.38; P < .001) were more likely to receive ≥10 days of antibiotic compared with those in pediatric clinics.

CONCLUSIONS

Antibiotic stewardship interventions that emphasize the duration of antibiotic therapy as well as the use of SNAPs or observation may be higher yield than those focusing on first-line therapy alone. Numerous system and patient level factors are associated with off-guideline prescribing.

Antibiotic Prescribing for Viral Respiratory Infections in the Pediatric Emergency Department and Urgent Care

BACKGROUND

Viral acute respiratory tract infections (vARTI) are a frequent source of inappropriate antibiotic prescribing. We describe the prevalence of antibiotic prescribing for vARTI in the pediatric emergency department (ED) and urgent care (UC) within a health system, and identify factors associated with overall and broad-spectrum antibiotic prescribing.

METHODS

Retrospective chart review within a single pediatric referral health system. Visits of patients, 3 months- 17 years old, with a discharge diagnosis of a vARTI from 2010 to 2015. Data collected included specific vARTI diagnosis, site type (ED or UC), provider type [pediatric emergency medicine subspecialist or physicians, nurse practitioners, physician assistants (non-PEM)] and discharge antibiotics. Odds ratios and 95% confidence intervals (CI) were calculated where appropriate.

RESULTS

There were 132,458 eligible visits, mean age 4.1 ± 4.3 years. Fifty-three percent were treated in an ED. Advanced practice providers, a term encompassing nurse practitioners and physician assistants, were the most common provider type (47.7%); 16.5% of patients were treated by a pediatric emergency medicine subspecialist. Antibiotics were prescribed for 3.8% (95% CI: 3.72-3.92) of children with vARTI; 25.4% (95% CI: 24.2-26.6) of these were broad-spectrum, most commonly first-generation cephalosporins (11%; 95% CI 10.2-11.9). Patients treated in an ED or by a non-PEM and those receiving chest radiograph (CXR) received antibiotics most frequently. Prescribing rates varied by specific vARTI diagnosis.

CONCLUSIONS

Patients discharged from the pediatric ED or UC with vARTI receive inappropriate antibiotics at a lower rate than reported in other community settings; however, they frequently receive broad-spectrum agents.

Guideline Adherence and Antibiotic Utilization by Community Pediatricians, Private Urgent Care Centers, and a Pediatric Emergency Department

Pediatric antibiotic prescriptions originate from an increasingly broad range of ambulatory settings. In this retrospective study, pharyngitis, otitis media, sinusitis, pneumonia, and upper respiratory infection cases, at 11 primary care offices, 2 independent urgent care centers (UCCs), and a pediatric emergency department in Western New York, were analyzed relative to medical society practice guidelines and antibiotic utilization. Of 2358 eligible visits across all sites, 25% were for study diagnoses, with 38% at UCC (P < .01). Across all sites, 26% of pharyngitis cases given antibiotics did not have diagnostic evidence of bacterial infection. At primary care offices and UCCs, guideline recommended first-line agents for pharyngitis and otitis media were used in only 58% and 63% of treated cases, respectively. Overall, an estimated 9855 to 12 045 avoidable antibiotic and 8030 non-guideline antibiotic courses annually are represented by the 14 sites studied. These and other study findings highlight numerous opportunities for outpatient pediatric antibiotic stewardship.

Antibiotic dispensing following pediatric visits in the US emergency departments and outpatient settings from 2006 to 2016

This study measured rates and trends in antibiotic dispensing for emergency department (ED) and outpatient visits by age groups. This retrospective analysis used data from the National Institutes of Health Collaboratory Distributed Research Network. The analysis included children (aged > 3 months to <12 years) and adolescents (aged 12 to <19 years) with or without an antibiotic dispensed within 3 days following visits for infectious diagnoses occurring from 2006 to 2016, with no antibiotic fills 90 days prior. Diagnoses were classified as: 1) respiratory tract infections (RTIs) for which antibiotics are mostly indicated; 2) RTIs for which antibiotics are mostly not indicated; 3) respiratory conditions for which antibiotics are never indicated; 4) infectious conditions beyond RTIs regardless of antibiotic indication. The largest annual decrease in any dispensed antibiotics (5% per year) was seen in ED visits for not indicated RTIs and never indicated respiratory conditions (incidence rate ratio [IRR] 0.95, 95% confidence interval [CI] 0.95-0.96). In outpatient settings, a 2% per year decrease was seen for not indicated RTIs and never indicated respiratory conditions (IRR 0.98, 95% CI 0.98-0.98). Broad-spectrum antibiotics had a 1% per year increase in outpatient settings for mostly indicated RTIs (IRR 1.01, 95% CI 1.01-1.01). Compared with adolescents, broad-spectrum antibiotic dispensing rates and trends were consistently higher for children regardless of diagnosis or care setting. Using national claims data, this real-world analysis found uneven decreases in potentially inappropriate antibiotic dispensing, suggesting the need for antibiotic stewardship interventions to become more common in outpatient settings.
