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

Treatment Failure and Adverse Events After Amoxicillin-Clavulanate vs Amoxicillin for Pediatric Acute Sinusitis

Importance

Acute sinusitis is one of the most common indications for antibiotic prescribing in children, with an estimated 4.9 million such prescriptions in the US annually. Consensus does not exist regarding the optimal empirical antibiotic.

Objective

To compare amoxicillin-clavulanate vs amoxicillin for the treatment of acute sinusitis in outpatient children.

Design, Setting, and Participants

Cohort study of children and adolescents aged 17 years or younger with a new outpatient diagnosis of acute sinusitis and a same-day new prescription dispensation of amoxicillin-clavulanate or amoxicillin in a nationwide health care utilization database. Propensity score matching was used to mitigate confounding.

Exposure

A new prescription dispensation of amoxicillin-clavulanate or amoxicillin.

Main Outcomes and Measures

Treatment failure, defined as an aggregate of a new antibiotic dispensation, emergency department or inpatient encounter for acute sinusitis, or inpatient encounter for a sinusitis complication, was assessed 1 to 14 days after cohort enrollment. Adverse events were evaluated, including gastrointestinal symptoms, hypersensitivity and skin reactions, acute kidney injury, and secondary infections.

Results

The cohort included 320 141 patients. After propensity score matching, there were 198 942 patients (99 471 patients per group), including 100 340 (50.4%) who were female, 101 726 (51.1%) adolescents aged 12 to 17 years, 52 149 (26.2%) children aged 6 to 11 years, and 45 067 (22.7%) children aged 0 to 5 years. Treatment failure occurred in 1.7% overall; 0.01% had serious failure (an emergency department or inpatient encounter). There was no difference in the risk of treatment failure between the amoxicillin-clavulanate and amoxicillin groups (relative risk [RR], 0.98 [95% CI, 0.92-1.05]). The risk of gastrointestinal symptoms (RR, 1.15 [95% CI, 1.05-1.25]) and yeast infections (RR, 1.33 [95% CI, 1.16-1.54]) was higher with amoxicillin-clavulanate. After patients were stratified by age, the risk of treatment failure after amoxicillin-clavulanate was an RR of 0.98 (95% CI, 0.86-1.12) for ages 0 to 5 years; RR was 1.06 (95% CI, 0.92-1.21) for 6 to 11 years; and RR was 0.87 (95% CI, 0.79-0.95) for 12 to 17 years. The age-stratified risk of adverse events after amoxicillin-clavulanate was an RR of 1.23 (95% CI, 1.10-1.37) for ages 0 to 5 years; RR was 1.19 (95% CI, 1.04-1.35) for 6 to 11 years; and RR was 1.04 (95% CI, 0.95-1.14) for 12 to 17 years.

Conclusions and Relevance

In children with acute sinusitis who were treated as outpatients, there was no difference in the risk of treatment failure between those who received amoxicillin-clavulanate compared with amoxicillin, but amoxicillin-clavulanate was associated with a higher risk of gastrointestinal symptoms and yeast infections. These findings may help inform decisions for empirical antibiotic selection in acute sinusitis.

The Potential Effects of Implementing an Antibiotic Stewardship Program by Integrating It with Medication Therapy Service in a Low-Income Serving Clinic - A Single-Center Experience

Background: Bacterial antimicrobial resistance (AMR) is a leading cause of mortality worldwide. Although AMR is common in low-income communities, there is limited evidence of the effect of antibiotic stewardship programs in low-income communities in the United States. Objectives: Our goal is to assess the effects of implementing pharmacist-led ASP by integrating it with medication therapy management service (MTM) in a low-income serving clinic. We evaluated the following 1) antibiotic prescriptions per 1000 patients, 2) the frequency of clinic (office) visits 30-day post-index clinic visits for recurring infections. Methods: To achieve our goal, we conducted a pre-post, quasi-experimental intervention study using an interrupted time-series analysis to assess the following: 1) antibiotic prescriptions per 1000 patients and the 2) frequency of office visits (including telehealth) within 30-day post-index clinic visits associated with recurrent infection. Results: Our findings revealed that the long-term effect of our antibiotic stewardship program intervention was associated with 63.69% reduction in antibiotic prescriptions per 1000 patients (change in slope = -0.173, [95% CI: (-0.30, -0.05)], P < 0.007) and a reduction in the frequency of office visits within 30-day post-index clinic visits by 67.27% (change in slope = -2.043, [95% CI: (-3.84, -0.24)], P < 0.028). Conclusion: Implementing antibiotic stewardship programs is feasible for clinics serving low-income populations. It was associated with a reduction in antibiotic prescriptions and preventable clinic (office) visits within 30 days due to infection recurrence.

Antibiotic Prescribing Practices for Upper Respiratory Tract Infections Among Primary Care Providers: A Descriptive Study

Background

Most antibiotics are prescribed in the ambulatory setting with estimates that up to 50% of use is inappropriate. Understanding factors associated with antibiotic misuse is essential to advancing better stewardship in this setting. We sought to assess the frequency of unnecessary antibiotic use for upper respiratory infections (URIs) among primary care providers and identify patient and provider characteristics associated with misuse.

Methods

Unnecessary antibiotic prescribing was assessed in a descriptive study by using adults ≥18 years seen for common URIs in a large, Upper Midwest, integrated health system, electronic medical records from June 2017 through May 2018. Individual provider rates of unnecessary prescribing were compared for primary care providers practicing in the departments of internal medicine, family medicine, or urgent care. Patient and provider characteristics associated with unnecessary prescribing were identified with a logistic regression model.

Results

A total of 49 463 patient encounters were included. Overall, antibiotics were prescribed unnecessarily for 42.2% (95% confidence interval [CI], 41.7–42.6) of the encounters. Patients with acute bronchitis received unnecessary antibiotics most frequently (74.2%; 95% CI, 73.4–75.0). Males and older patients were more likely to have an unnecessary antibiotic prescription. Provider characteristics associated with higher rates of unnecessary prescribing included being in a rural practice, having more years in practice, and being in higher volume practices such as an urgent care setting. Fifteen percent of providers accounted for half of all unnecessary antibiotic prescriptions.

Conclusions

Although higher-volume practices, a rural setting, or longer time in practice were predictors, unnecessary prescribing was common among all providers.

Antimicrobial stewardship program in pediatric medicine

The rising threats from antimicrobial resistance due to inappropriate utilization of antimicrobial agents in health care including the pediatric population has been a topic of concern at the global level for the last several decades. The antimicrobial stewardship program (ASP) is a multidisciplinary institutional initiative focusing primarily on the improvement of antimicrobial prescribing practices and limiting inappropriate use. ASPs play an important role in the implementation of healthcare strategies in pediatrics worldwide to reduce antimicrobial resistance. Many published reports demonstrate how adapted ASPs in pediatrics result in improvement of unnecessary antimicrobial utilization, decreasing drug resistance and treatment failure, minimization of adverse clinical outcomes, decreasing healthcare costs and hospital length of stay, and optimization of diagnostic strategies. However, some barriers in pediatric ASP still exist. This narrative review describes core elements of ASP, the impact of implemented ASPs on pediatric healthcare, and challenges of pediatric ASP as seen by the authors.

Rückgang der ambulanten Antibiotikaverordnungen bei Kindern und Jugendlichen in Deutschland 2010–2019. Regionale Entwicklung in den deutschen KV-Regionen

In den letzten 10 Jahren ist das Thema Antibiotic Stewardship (ABS) auch in der ambulanten Kinder- und Jugendmedizin immer stärker in den Vordergrund gerückt. Die vom Zentralinstitut für die kassenärztliche Versorgung in der Bundesrepublik Deutschland regelmäßig ausgewerteten bundesweiten krankenkassenübergreifenden Arzneiverordnungsdaten gemäß § 300 Abs. 2 SGB V (gesetzlich Krankenversicherte) zeigen von 2010 bis 2019 eine starke Abnahme der Antibiotikaverordnungsraten bei Kindern und Jugendlichen (0 bis 14 Jahre) pro 1000 Versicherte, insbesondere bei Säuglingen (∆ −53 %) und Kleinkindern (∆ −46 %). Aus ABS-Perspektive werden weiterhin zu häufig Oralcephalosporine (v. a. Cefaclor und Cefuroxim) verordnet. Zudem persistieren starke regionale Unterschiede, die sich nicht durch Unterschiede in der Patientenpopulation oder im Erkrankungsspektrum erklären lassen.
