<p><strong>BACKGROUND: </strong>The microbiologic etiologies, clinical manifestations, and antimicrobial treatment of neonatal infections differ substantially from infections in adult and pediatric patient populations. In 2019, the Centers for Disease Control and Prevention developed neonatal-specific (Standardized Antimicrobial Administration Ratios SAARs), a set of risk-adjusted antimicrobial use metrics that hospitals participating in the National Healthcare Safety Network's (NHSN's) antimicrobial use surveillance can use in their antibiotic stewardship programs (ASPs).</p>

<p><strong>METHODS: </strong>The Centers for Disease Control and Prevention, in collaboration with the Vermont Oxford Network, identified eligible patient care locations, defined SAAR agent categories, and implemented neonatal-specific NHSN Annual Hospital Survey questions to gather hospital-level data necessary for risk adjustment. SAAR predictive models were developed using 2018 data reported to NHSN from eligible neonatal units.</p>

<p><strong>RESULTS: </strong>The 2018 baseline neonatal SAAR models were developed for 7 SAAR antimicrobial agent categories using data reported from 324 neonatal units in 304 unique hospitals. Final models were used to calculate predicted antimicrobial days, the SAAR denominator, for level II neonatal special care nurseries and level II/III, III, and IV NICUs.</p>

<p><strong>CONCLUSIONS: </strong>NHSN's initial set of neonatal SAARs provides a way for hospital ASPs to assess whether antimicrobial agents in their facility are used at significantly higher or lower rates compared with a national baseline or whether an individual SAAR value is above or below a specific percentile on a given SAAR distribution, which can prompt investigations into prescribing practices and inform ASP interventions.</p>

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

<p><strong>BACKGROUND: </strong>Antibiotics are commonly prescribed for children with acute respiratory infections (ARIs). This study describes the distribution of ARI diagnoses and specifically quantifies antibiotic dispensing for bronchitis and upper respiratory infection (URI) by treatment setting and specialty.</p>

<p><strong>METHODS: </strong>This retrospective, observational cross-sectional study used data from the HealthCore Integrated Research Environment containing claims from 14 commercial health plans for 2012 to 2014. Children (2-17 years) with first-episode ARI were identified by diagnosis of acute otitis media (AOM), sinusitis, pharyngitis, bronchitis or URI with no competing infections or chronic illnesses. Treatment setting was where diagnoses were made: primary care offices, urgent care centers (UCC), retail health clinics (RHCs) or emergency departments. Primary outcome measure was antibiotic prescription fills from pharmacies within 2 days of start of ARI episode.</p>

<p><strong>RESULTS: </strong>For URI, the highest proportions in antibiotic dispensing were ordered by office-based or UCC family physicians (28% and 30%, respectively) and office-based or UCC nurse practitioners/physician assistants (30% and 29%, respectively). Across all settings and specialties, there was high proportion of antibiotic dispensing for bronchitis (75%). Overall, 48% of 544,531 children diagnosed with ARI filled antibiotics. Nurse practitioners/physician assistants in RHC made the most diagnoses of AOM (24%) and streptococcal pharyngitis (22%).</p>

<p><strong>CONCLUSIONS: </strong>Outreach efforts to decrease antibiotic dispensing for URI can be focused on office-based and UCC family physicians and nurse practitioners/physician assistants. All specialties need widespread interventions to reduce antibiotic dispensing for bronchitis. RHC nurse practitioners/physician assistants can be targeted to reduce high proportion of AOM and streptococcal pharyngitis diagnoses.</p>

Prevalence of Inappropriate Antibiotic Prescriptions Among US Ambulatory Care Visits, 2010-2011.

<p><strong>IMPORTANCE: </strong>The National Action Plan for Combating Antibiotic-Resistant Bacteria set a goal of reducing inappropriate outpatient antibiotic use by 50% by 2020, but the extent of inappropriate outpatient antibiotic use is unknown.</p>

<p><strong>OBJECTIVE: </strong>To estimate the rates of outpatient oral antibiotic prescribing by age and diagnosis, and the estimated portions of antibiotic use that may be inappropriate in adults and children in the United States.</p>

<p><strong>DESIGN, SETTING, AND PARTICIPANTS: </strong>Using the 2010-2011 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, annual numbers and population-adjusted rates with 95% confidence intervals of ambulatory visits with oral antibiotic prescriptions by age, region, and diagnosis in the United States were estimated.</p>

<p><strong>EXPOSURES: </strong>Ambulatory care visits.</p>

<p><strong>MAIN OUTCOMES AND MEASURES: </strong>Based on national guidelines and regional variation in prescribing, diagnosis-specific prevalence and rates of total and appropriate antibiotic prescriptions were determined. These rates were combined to calculate an estimate of the appropriate annual rate of antibiotic prescriptions per 1000 population.</p>

<p><strong>RESULTS: </strong>Of the 184,032 sampled visits, 12.6% of visits (95% CI, 12.0%-13.3%) resulted in antibiotic prescriptions. Sinusitis was the single diagnosis associated with the most antibiotic prescriptions per 1000 population (56 antibiotic prescriptions [95% CI, 48-64]), followed by suppurative otitis media (47 antibiotic prescriptions [95% CI, 41-54]), and pharyngitis (43 antibiotic prescriptions [95% CI, 38-49]). Collectively, acute respiratory conditions per 1000 population led to 221 antibiotic prescriptions (95% CI, 198-245) annually, but only 111 antibiotic prescriptions were estimated to be appropriate for these conditions. Per 1000 population, among all conditions and ages combined in 2010-2011, an estimated 506 antibiotic prescriptions (95% CI, 458-554) were written annually, and, of these, 353 antibiotic prescriptions were estimated to be appropriate antibiotic prescriptions.</p>

<p><strong>CONCLUSIONS AND RELEVANCE: </strong>In the United States in 2010-2011, there was an estimated annual antibiotic prescription rate per 1000 population of 506, but only an estimated 353 antibiotic prescriptions were likely appropriate, supporting the need for establishing a goal for outpatient antibiotic stewardship.</p>

Race, otitis media, and antibiotic selection.

<p><strong>BACKGROUND AND OBJECTIVE: </strong>Previous research suggests that physicians may be less likely to diagnose otitis media (OM) and to prescribe broad-spectrum antibiotics for black versus nonblack children. Our objective was to determine whether race is associated with differences in OM diagnosis and antibiotic prescribing nationally.</p>

<p><strong>METHODS: </strong>We examined OM visit rates during 2008 to 2010 for children ≤14 years old using the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey. We compared OM visits between black and nonblack children, as percentages of all outpatient visits and visit rates per 1000. We compared antibiotic prescribing by race as the percentage of OM visits receiving narrow-spectrum (eg, amoxicillin) versus broader-spectrum antibiotics. We used multivariable logistic regression to examine whether race was independently associated with antibiotic selection for OM.</p>

<p><strong>RESULTS: </strong>The percentage of all visits resulting in OM diagnosis was 30% lower in black children compared with others (7% vs 10%, P = .004). However, OM visits per 1000 population were not different between black and nonblack children (253 vs 321, P = .12). When diagnosed with OM during visits in which antibiotics were prescribed, black children were less likely to receive broad-spectrum antibiotics than nonblack children (42% vs 52%, P = .01). In multivariable analysis, black race was negatively associated with broad-spectrum antibiotic prescribing (adjusted odds ratio 0.59; 95% confidence interval, 0.40-0.86).</p>

<p><strong>CONCLUSIONS: </strong>Differences in treatment choice for black children with OM may indicate race-based differences in physician practice patterns and parental preferences for children with OM.</p>
