Abstract

Introduction: Antibiotic resistance represents one of the most critical public health challenges globally. Antibiotic use, especially inappropriate use, is a major driver for antibiotic resistance. Previously Black and Hispanic populations have been shown to experience overall higher antibiotic prescribing rates in ambulatory settings. Recognizing inappropriate prescribing trends within racial and ethnic groups will aid in finding ways to mitigate these issues in clinical practice. This study evaluates racial and ethnic trends of outpatient antibiotic prescribing for acute respiratory tract infections from January 2017 to December 2021.

Research Question or Hypothesis: How do outpatient antibiotic prescribing patterns for acute respiratory tract infections in the US differ across racial and ethnic groups from 2017 to 2021?

Study Design: We performed the analysis using nationally representative data from the Medical Expenditure Panel Surveys from January 2017 to December 2021. Trends in population-based prescribing are examined for antibiotics prescribed for acute respiratory tract infections, which we defined as nasopharyngitis, bronchiolitis, bronchitis, pharyngitis, and sinusitis. We assess prescribing patterns in Black, White, Asian, and Hispanic populations.

Methods: Prescription rates are defined as the annual number of antibiotic prescriptions divided by the overall US civilian non-institutionalized population. Population denominators are derived from the MEPS. Acute respiratory tract infections are identified using ICD10 codes. All analyses are adjusted to account for the MEPS complex study design using weights, clustering, and stratification to derive national estimates.

Results: Pending.

Conclusion: Pending.
