Antimicrobial resistance in patients with COVID-19: a systematic review and meta-analysis

Frequent antibiotic use in COVID-19 patients exacerbates antimicrobial resistance. This systematic review and meta-analysis determined the prevalence and predictors of bacterial infections and antimicrobial resistance in COVID-19 patients. 148 studies (362,976 patients) showed a 5.3% prevalence of bacterial co-infection and 18.4% of secondary bacterial infection. Antimicrobial resistance was highly prevalent (60.8% of infections and 37.5% of isolates). Higher resistance was associated with low-income/middle-income settings, ICU admission, IL-6 inhibitor use, and diabetes. The study highlights the urgent need for global surveillance and careful antibiotic use in COVID-19 patients.
