Background Antibiotic prescription rates can be affected by pandemic measures such as lockdowns, social distancing, and remote consultations in general practice. Therefore, such emergency states may negatively affect antimicrobial stewardship, specifically in out-of-hours (OOH) primary care. As contact patterns changed in the COVID-19 pandemic, it would be relevant to explore the impact on antimicrobial stewardship.Aim To study the impact of the pandemic on antibiotic prescription rates in OOH primary care, overall and per age group.Methods This cross-sectional register-based study used routine data from OOH primary care in the Central Denmark Region. We included all patient contacts in two equivalent time periods: pre-pandemic and pandemic period. The main outcome measure was defined as the number of antibiotic prescriptions per contact (antibiotic prescription rate).Results The overall antibiotic prescription rate decreased during the first year of the pandemic compared to the pre-pandemic period (RR = 0.97, 95%CI: 0.96–0.98). Likewise, the rate decreased for clinic consultations (RR = 0.63, 95%CI: 0.62–0.64). However, an increase was seen for telephone consultations (RR = 1.73, 95%CI: 1.70–1.76). The decline in clinic consultations was largest for consultations involving children aged 0–10 years (RR = 0.53, 95%CI: 0.51–0.56).Conclusion Antibiotic prescription rates in Danish OOH primary care decreased during the first year of the COVID-19 pandemic, especially for young children. Prescription rates decreased in clinic consultations, whereas the rates increased in telephone consultations. Further research should explore if antibiotic prescription rates have returned to pre-pandemic levels, and if the introduction of video consultations has affected antibiotic prescription patterns in OOH primary care.
