Abstract Background: The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted the prevalence and antibiotic sensitivity patterns of multidrug-resistant organisms (MDROs). This study aimed to investigate the MDRO incidence and antibiotic sensitivity trends before, during, and after the COVID-19 pandemic at Dr. M. Djamil Central General Hospital in Padang, Indonesia. Methods: A total of 5539 clinical samples were collected and analyzed using the VITEK2 system to identify MDRO types. The study periods were defined as before (prepandemic), during, and after the COVID-19 pandemic. Results: The incidence of MDROs increased significantly during and after the pandemic, with 1.64 and 1.42 times higher rates compared to the prepandemic period, respectively. Specific MDRO types that showed increased prevalence included Escherichia coli -producing extended-spectrum β-lactamases (Eco-ESBL), carbapenem-resistant Klebsiella pneumoniae (CRKP), carbapenem-resistant E. coli (CREC), carbapenem-resistant Pseudomonas aeruginosa (CRPA), carbapenem-resistant Acinetobacter baumannii (CRAB), and methicillin-resistant Staphylococcus aureus (MRSA). Antibiotic sensitivity decreased during and after the pandemic for K. pneumoniae -producing ESBL s, CRKP, and CRAB, as well as for CREC and CRPA during the pandemic. In contrast, antibiotic sensitivity increased for Eco-ESBL and MRSA during and after the pandemic. Conclusion: The COVID-19 pandemic has significantly contributed to the increased incidence of MDROs and decreased antibiotic effectiveness against these pathogens in the study setting. These findings highlight the need for comprehensive infection control measures and antimicrobial stewardship programs to mitigate the impact of the pandemic on MDRO epidemiology.
