Abstract

Abstract: Background: The COVID-19 pandemic led to rapid changes in demand and delivery of primary care services that could have led to increases in antibiotic prescribing. Objective: We investigated the impact of the COVID-19 pandemic on oral antibiotic dispensing rates in primary care in Wales using longitudinal analysis of monthly oral antibiotic dispensing data from 1 April 2018 to 30 April 2021. Methods: We used All-Wales primary care dispensing data. We examined trends in oral antibiotic dispensing per 1, 000 people for Wales and for individual Health Boards. We used interrupted time series analysis to estimate changes in trends pre- and post-April 2020 to assess the impact of the first and subsequent lockdowns. Results: Between April 2020 and April 2021, antibiotic dispensing in Wales was lower compared with the same period in 2018 and 2019, with an average monthly decrease of 14.00 dispensed items per 1, 000 registered patients (95% confidence interval 19.89–8.11). The overall prepandemic monthly antibiotic dispensing rate ranged from 48.5 to 67.4 antibiotic items per 1, 000 registered patients. From the onset of the pandemic, it ranged from 40.3 to 49.07 antibiotic items per 1, 000 registered patients. This reduction was primarily driven by narrow-spectrum antibiotics. Statistically significant reductions were also observed for antibiotics commonly dispensed for the treatment of respiratory tract infections. Dispensing of antibiotics primarily used for urinary and skin infections remained stable. Conclusions: Despite complexities of consulting during the COVID-19 pandemic in primary care we found no evidence of an increase in antibiotic dispensing during this time. Lay Summary: A considerable amount of work has been done in recent years to reduce unnecessary antibiotic prescribing. The COVID-19 pandemic has changed the way patients interact with their General Practitioners (GPs), with more consultations being undertaken remotely, either over the phone or online, with less face-to-face contact. It is not clear how these changes have affected antibiotic prescribing by GPs. We looked at the number of antibiotic items dispensed in Wales between April 2018 and April 2021 to assess the impact of the first lockdown. Fewer antibiotics were dispensed from April 2020 to April 2021, compared with the period before the COVID-19 pandemic (April 2018–March 2020). Dispensing of antibiotics used to treat chest, ear, and throat infections reduced following the start of the UK lockdown. There was no change in dispensing of antibiotics used to treat skin and urine infections. Reassuringly, dispensing of antibiotics that target several different types of bacteria (broad-spectrum antibiotics) did not increase during the COVID-19 pandemic.
