BACKGROUND: A wide range of bacterial infections occur in coronavirus disease 2019 (COVID-19) patients, particularly in those with severe coronaviral disease. Some of these are community-acquired co-infections. OBJECTIVE: To review recent data that indicate the occurrence of hospital-onset bacterial infections, including with antibiotic-resistant isolates, in COVID-19 patients. SOURCES: Using PubMed, the literature was searched using terms including: 'COVID-19'; 'SARS-CoV-2'; 'bacterial infection'; 'healthcare-associated infection'; 'antibiotic resistance'; 'antimicrobial resistance'; 'multi-drug resistance'; 'Streptococcus'; 'Staphylococcus'; 'Pseudomonas'; 'Escherichia'; 'Klebsiella'; 'Enterococcus'; 'Acinetobacter'; 'Haemophilus'; 'MRSA'; 'VRE'; 'ESBL'; 'NDM-CRE'; 'CR-Ab'; 'VRSA'; 'MDR'. CONTENT: There is a growing number of reports of bacterial infections acquired by patients with severe COVID-19 after hospital admission. Antibiotic-resistant pathogens found to cause healthcare-associated infections (HAIs) in COVID-19 patients include methicillin-resistant Staphylococcus aureus, New Delhi metallo-beta-lactamase-producing carbapenem-resistant Enterobacterales, carbapenem-resistant Acinetobacter baumannii, extended-spectrum beta-lactamase Klebsiella pneumoniae and vancomycin-resistant enterococci. COVID-19 has impacted bacterial HAIs in a number of ways with an increase in the incidence of New Delhi metallo-beta-lactamase-producing carbapenem-resistant Enterobacterales and carbapenem-resistant A. baumannii reported at some hospital sites compared with before the pandemic. Recommended guidelines for antimicrobial stewardship in COVID-19 patient treatment are discussed regarding minimization of empiric broad-spectrum antibiotic use. Other studies have reported a decrease in methicillin-resistant S. aureus and vancomycin-resistant enterococci cases, which has been attributed to enhanced infection prevention and control practices introduced to minimize intra-hospital spread of COVID-19. IMPLICATIONS: Poorer outcomes have been observed in hospitalized COVID-19 patients with an antibiotic-resistant infection. Although heightened IPC measures have been accompanied by a reduction in some HAIs at specific sites, in other situations, COVID-19 has been associated with an increase in bacterial HAI incidence. Further research is needed to define the cost-benefit relationship of maintaining COVID-19-related infection prevention and control protocols beyond the pandemic to reduce the burden of HAIs. In addition, the longer-term impact of high usage of certain broad-spectrum antibiotics during the COVID-19 pandemic requires evaluation.
