Respiratory antibacterial prescribing in primary care and the COVID-19 pandemic in England, winter season 2020-21.

Abstract

BackgroundAntibacterial prescribing for respiratory tract infections (RTIs) accounts for almost half of all prescribing in primary care. Nearly a quarter of antibacterial prescribing in primary care is estimated to be inappropriate, the greatest being for RTIs. The COVID-19 pandemic has changed the provision of healthcare services and impacted the levels of antibacterials prescribed.ObjectivesTo describe the changes in community antibacterial prescribing for RTIs in winter 2020–21 in England.MethodsRTI antibacterial prescribing was measured in prescription items/1000 population for primary care from January 2014 and in DDDs/1000 population/day for the totality of RTI prescribing [combined with Accident & Emergency (A&E) in secondary care], from January 2016 to February 2021. Trends were assessed using negative binomial regression and seasonally adjusted interrupted time-series analysis.ResultsAntibacterials prescribed for RTIs reduced by a further 12.4% per season compared with pre-COVID (P < 0.001). In winter 2020–21, RTI prescriptions almost halved compared with the previous winter in 2019–20 (P < 0.001). The trend observed for total RTI prescribing (primary care with A&E) was similar to that observed in the community alone.ConclusionsDuring COVID-19, RTI prescribing reduced in the community and the expected rise in winter was not seen in 2020–21. We found no evidence that RTI prescribing shifted from primary care to A&E in secondary care. The most likely explanation is a decrease in RTIs and presentations to primary care associated with national prevention measures for COVID-19.
