Profiles of multidrug-resistant organisms among patients with bacteremia in intensive care units: an international ID-IRI survey

AbstractEvaluating trends in antibiotic resistance is a requisite. The study aimed to analyze the profile of multidrug-resistant organisms (MDROs) among hospitalized patients with bacteremia in intensive care units (ICUs) in a large geographical area. This is a 1-month cross-sectional survey for blood-borne pathogens in 57 ICUs from 24 countries with different income levels: lower-middle-income (LMI), upper-middle-income (UMI), and high-income (HI) countries. Multidrug-resistant (MDR), extensively drug-resistant (XDR), or pan-drug-resistant isolates were searched. Logistic regression analysis determined resistance predictors among MDROs. Community-acquired infections were comparable to hospital-acquired infections particularly in LMI (94/202; 46.5% vs 108/202; 53.5%). Although MDR (65.1%; 502/771) and XDR (4.9%; 38/771) were common, no pan-drug-resistant isolate was recovered. In total, 32.1% of MDR wereKlebsiella pneumoniae, and 55.3% of XDR wereAcinetobacter baumannii. The highest MDR and XDR rates were in UMI and LMI, respectively, with no XDR revealed from HI. Predictors of MDR acquisition were male gender (OR, 12.11; 95% CI, 3.025 –15.585) and the hospital-acquired origin of bacteremia (OR, 2.643; 95%CI, 1.462–3.894), and XDR acquisition was due to bacteremia in UMI (OR, 3.344; 95%CI, 1.189–5.626) and admission to medical-surgical ICUs (OR, 1.481; 95% CI, 1.076–2.037). We confirm the urgent need to expand stewardship activities to community settings especially in...
