The use of systemic antibiotics in ambulatory care in Hungary decreased by 23.22% during the COVID-19 pandemic compared to pre-COVID levels. The reduction was significant in the use of beta-lactam antibacterials, penicillins (J01C, -26.3%), and quinolones (J01M, -36.5%). The trends of antibiotic use corresponded with the implementation and lifting of restriction measures, reaching a nadir in May 2020 with a 55.46% decrease compared to the previous year. Overall, antibiotic use in ambulatory care remained lower during the pandemic period, except for the months of September to November 2021, and seasonal variation in use diminished. Excessive use of azithromycin, despite its ineffectiveness for COVID-19, was observed at the active agent level.
The COVID-19 pandemic and related restrictions have potentially impacted the use of antibiotics. We aimed to analyze the use of systemic antibiotics (J01) in ambulatory care in Hungary during two pandemic years, to compare it with pre-COVID levels (January 2015-December 2019), and to describe trends based on monthly utilization. Our main findings were that during the studied COVID-19 pandemic period, compared to the pre-COVID level, an impressive 23.22% decrease in the use of systemic antibiotics was detected in ambulatory care. A significant reduction was shown in the use of several antibacterial subgroups, such as beta-lactam antibacterials, penicillins (J01C, -26.3%), and quinolones (J01M, -36.5%). The trends of antibiotic use moved in parallel with the introduction or revoking of restriction measures with a nadir in May 2020, which corresponded to a 55.46% decrease in use compared to the previous (pre-COVID) year's monthly means. In general, the systemic antibiotic use (J01) was lower compared to the pre-COVID periods' monthly means in almost every studied pandemic month, except for three months from September to November in 2021. The seasonal variation of antibiotic use also diminished. Active agent level analysis revealed an excessive use of azithromycin, even after evidence of ineffectiveness for COVID-19 emerged.
