There is conflicting evidence regarding the impact of the Coronavirus 2019 (COVID-19) pandemic on antimicrobial resistance, with few studies conducted in low- and middle-income countries. We investigated the impact of the COVID-19 pandemic on multidrug resistant organisms (MDROs) among critically ill patients and their clinical outcomes.This was a retrospective observational study of patients admitted to the medical Intensive Care Unit at Jordan University Hospital and had blood, urine, or bronchoalveolar bacterial cultures taken during 2 time periods: prepandemic (ie, 1/2016 to 1/2019) and pandemic (ie, 1/2020 to 1/2023). We compared the clinical outcomes (ie, in-hospital deaths, the need for O2 devices, intubation, the length of hospital stay, and the occurrence of complications) and prevalence of MDROs between the 2 periods and conducted multivariate analyses.There were 1,254 patients (479 prepandemic and 775 postpandemic. The percentage of patients who had MDROs was significantly higher among patients with a culture taken during the pandemic (82.4%) compared to before it (17.6%) (P-value=.000). Multivariate analysis demonstrated that patients cultured during the pandemic were more than 3 times as likely to have an MDRO (odds ratio = 3.210; 95% confidence interval: 2.236-4.609).The increase in MDROs during the COVID-19 pandemic is an alarming threat to public health; thus, investigating the antibiotic resistance situation as the pandemic subsides is crucial.
