Since the novel coronavirus pandemic began, limited data from small studies in several countries have indicated high rates of antibiotic prescribing in COVID-19 patients and low rates of bacterial co-infections, raising concerns about unnecessary antibiotic use and the pandemic's potential impact on antimicrobial resistance (AMR).A new study from researchers in Michigan highlights some of those concerns.In the study, published in Clinical Infectious Diseases, researchers looked at data on more than 1,700 hospitalized COVID-19 patients treated at 38 Michigan hospitals from Mar 13 to Jun 18 and found that more than half received early antibiotic therapy, with antibiotic use as high as 84% in some hospitals.
