PRO: The COVID-19 pandemic will result in increased antimicrobial resistance rates

Area of Science:

• Public Health
• Infectious Diseases
• Microbiology

Background:

• The COVID-19 pandemic has led to increased use of broad-spectrum antibiotics in hospitalized patients.
• This antibiotic use often exceeds rates of secondary infections, indicating potential overuse.
• COVID-19 patients with underlying health conditions are at higher risk for both severe disease and antimicrobial resistance (AMR) infections.

Purpose of the Study:

• To analyze the impact of the COVID-19 pandemic on the emergence and spread of antimicrobial resistance (AMR).
• To identify factors contributing to increased AMR during the pandemic, including prescribing patterns and patient risk factors.

Main Methods:

• Review of antibiotic prescribing practices in COVID-19 patients.
• Analysis of secondary infection rates in hospitalized COVID-19 cases.
• Examination of epidemiological data linking COVID-19 epicenters with AMR prevalence.

Main Results:

• Broad-spectrum antibiotic prescribing is high among COVID-19 patients, often without documented secondary infections.
• Antimicrobial resistance (AMR) selection pressure is intensified in COVID-19 hotspots and dedicated hospital units.
• COVID-19 epicenters often overlap with existing antimicrobial resistance (AMR) hotspots, exacerbating the problem.

Conclusions:

• The COVID-19 pandemic is a significant driver for increased antimicrobial resistance (AMR) globally.
• Factors such as increased antibiotic use, patient vulnerability, and disruption of healthcare systems contribute to AMR spread.
• The impact of COVID-19 on AMR will be uneven, varying by location, healthcare facility, and specific hospital units.
