RESUMO
Introduction: Reducing inappropriate antibiotic prescribing tempers the growing threat of antimicrobial resistance. We aimed to quantify the associated impact of COVID-19-related national restrictions in England on dental antibiotic dispensing and describe changes in appointments and modes of delivery of care. Methods: Interrupted time series analyses were completed using NHS Business Service Authority (NHSBSA) ePACT2 data to measure the associated change in antibiotic dispensing in England following COVID-19-related restrictions (which began March 2020). For face-to-face dental consultations, NHS dental treatment plan (FP17) data were used. For remote consultations during the COVID-19 period, NHSBSA Compass system remote management data were used. Results: Between January 2016 and February 2020, there was a decreasing trend in antibiotic dispensing (-0.02 per 1000 population per month, Pâ<â0.05). In contrast, there was an increase of 0.98 per 1000 population (Pâ<â0.05) in March. The peak in antibiotic use occurred between June 2020 and July 2020, once the restrictions were eased. At the end of the study period (July 2021), the elevated prescribing trend had not returned to pre-pandemic counterfactual levels, although exhibiting a declining trend. A stable trend in dental treatment plans was seen pre-COVID-19, with a sharp decline coinciding with the restrictions. Dental treatment plans had not yet returned to the higher pre-pandemic levels. Conclusions: Dental antibiotic prescribing significantly increased with the national COVID-19 restrictions when service delivery was altered with the closure of dental practices and introduction of remote consultations. Teledentistry was likely associated with inappropriate antibiotic prescribing. Continued antimicrobial stewardship and prudent use of antibiotics in dentistry is important.
