Abstract:
A saturated health care system with a lack of evidence-based antiviral medicine and ignorance of antimicrobial stewardship during pandemics has prompted clinicians to prescribe a broad-spectrum antibiotic more often. A prospective, cross-sectional study of COVID-infected patients was conducted to gain insight into antibiotic prescribing practices and their impact on antimicrobial resistance. The antibiotic susceptibility test was performed using the disc diffusion method. 318 patients met the study's inclusion criteria, with a mean age of 46 years and 55% (175) of them being males. Antibiotics were prescribed for 93.72% (209) of mild cases, 92.45% (49) of moderate cases, 96.15% (25) of severe cases, and 100% (16) of critical cases of COVID-19. A total of 95 samples were sent in for culture and antibiotic sensitivity testing, with 58.95% (56) confirming growth. The majority of the growth was found to contain E. coli (14). In 54.9% of cases, antibiotics with less than 50% sensitivity to curing bacterial infection were detected. In the study, we found that antibiotics were being used unnecessarily in excessive quantities and that more than half of the antibiotics were less sensitive to isolated bacteria.
Insights
During pandemics, broad-spectrum antibiotics were overused in COVID-19 patients, leading to excessive quantities and reduced effectiveness against bacterial infections. This highlights a critical need for better antimicrobial stewardship and evidence-based treatments.
Area of Science:
- Infectious Diseases
- Microbiology
- Public Health
Background:
- Pandemics strain healthcare systems, often leading to suboptimal prescribing of antibiotics.
- Lack of evidence-based antivirals and poor antimicrobial stewardship contribute to broad-spectrum antibiotic overuse.
- COVID-19 pandemic exacerbated these issues, prompting investigation into antibiotic use in infected patients.
Purpose of the Study:
- To investigate antibiotic prescribing patterns in COVID-19 patients.
- To assess the impact of these practices on antimicrobial resistance.
- To evaluate the sensitivity of prescribed antibiotics against isolated bacterial pathogens.
Main Methods:
- Prospective, cross-sectional study design.
- Inclusion of 318 COVID-19 patients.
- Antibiotic susceptibility testing using the disc diffusion method on 95 patient samples.
Main Results:
- Antibiotics were prescribed in over 90% of all COVID-19 severity cases.
- Bacterial growth confirmed in 58.95% of cultured samples, with E. coli being the most common.
- Over 54.9% of detected antibiotics showed less than 50% sensitivity against the isolated bacteria.
Conclusions:
- Antibiotics were frequently overprescribed in COVID-19 patients, irrespective of disease severity.
- High rates of antibiotic use correlated with reduced sensitivity to common bacterial pathogens like E. coli.
- Urgent need for improved antimicrobial stewardship and evidence-based treatment guidelines during pandemics to combat rising antimicrobial resistance.
