Impact of the COVID-19 pandemic on the utilisation and quality of antibiotic use in the Scottish primary care setting: a population-based segmented interrupted time-series analysis.

Background: Inappropriate use of antibiotics is expected to increase during the COVID-19 pandemic, but there are limited data on COVID-19's long-term impact. We assessed the impact of COVID-19 on the quantity and quality of antibiotic use in Scotland.

Research Design And Methods: A segmented interrupted time series was applied to monthly dispensed antibiotics using prescription cost analysis data from March/2019 to March/2023.
