This study aimed to update the incidence of device-associated healthcare-associated infections (DA-HAIs), and to characterize pathogen distribution and carbapenem-resistant Enterobacteriaceae (CRE) detection among ICU patients in Shanghai, China. Prospective surveillance in 223 ICUs using standardized International Nosocomial Infection Control Consortium methodology (INICC) protocols collected patient-level data on demographics, microbiology, device use, and DA-HAIs. Trends, annual percent change (APC) and average annual percent change (AAPC) were estimated using Joinpoint regression models. The overall DA-HAIs incidence density in ICUs was 1.67 per 1000 catheter-days for catheter-associated urinary tract infection (CAUTI) (95% CI: 1.62-1.73), 0.59 per 1000 central line-days for central line-associated bloodstream infection (CLABSI) (95% CI: 0.56-0.63), and 4.63 per 1000 ventilator-days for ventilator-associated pneumonia (VAP) (95% CI: 4.51-4.76). Significant reductions were observed in VAP (AAPC: -15.36%; P < 0.001) and CLABSI (AAPC: -11.23%; P < 0.001). Pathogen distributions varied by infection type, with Enterococcus faecium (17.22%) and Klebsiella pneumoniae (16.63%) predominating in CAUTI patients, Klebsiella pneumoniae (26.87%) in CLABSI patients, and Acinetobacter baumannii (37.60%) in VAP patients. The overall CRE detection rate was 33.67% in CAUTI patients, 37.56% in CLABSI patients, and 35.24% in VAP patients. Although DA-HAI rates showed significant declines, the persistently high CRE prevalence underscores substantial antimicrobial resistance challenges in Chinese ICUs.
