BACKGROUND: Infections are a leading cause of death in patients with cancer, but the proportion and rate of antimicrobial resistance (AMR) in hospitalized patients with cancer are not well understood. METHODS: This retrospective, cross-sectional evaluation of AMR assessed hospitalized adult patients in 168 United States (US) healthcare facilities between April 2018 and December 2022. Nonduplicate, noncontaminant Gram-negative and Gram-positive bacteria recovered from various samples (blood, respiratory, urine, etc.) were used to assess the rate of AMR pathogens per 1000 admissions and the proportion of AMR among bacterial isolates in patients with and without cancer. FINDINGS: Among 4,612,620 admissions, 6.4% (297,500) were of patients with cancer and 93.6% (4,315,120) were of patients without cancer. AMR pathogen rates were higher in cancer patients than patients without cancer for most pathogen groups, including vancomycin-resistant enterococci with incidence rate ratio (IRR), 1.95 (95% confidence interval [CI], 1.84, 2.07), extended-spectrum beta-lactamase (ESBL) producers (IRR, 1.48 [95% CI, 1.43, 1.53]), carbapenem-nonsusceptible Enterobacterales (IRR, 1.46 [95% CI, 1.32, 1.61]), and multidrug-resistant Pseudomonas aeruginosa (IRR, 1.31 [95% CI, 1.18, 1.45]). The percentage of nonsusceptible isolates in most pathogen groups was lower in patients with versus without cancer except for ESBL producers among Enterobacterales (odds ratio (OR), 1.11 [95% CI, 1.07, 1.15]) and va...
