Infection Control in the Era of Antimicrobial Resistance in China: Progress, Challenges, and Opportunities

Area of Science:

• Infectious Diseases
• Microbiology
• Public Health

Background:

• China implemented nationwide infection control in 1986, developing extensive guidelines and hospital infection control teams.
• Despite these measures, compliance remains suboptimal, leading to challenges in healthcare settings.

Purpose of the Study:

• To analyze the trends of multidrug-resistant organisms (MDROs) in China over the past three decades.
• To identify the primary drivers and high-risk lineages contributing to the spread of specific MDROs.

Main Methods:

• Review of infection control implementation and regulations in China since 1986.
• Analysis of incidence trends for key MDROs, including CRAB, CRKP, carbapenem-resistant Pseudomonas aeruginosa, MRSA, and VRE.
• Identification of dominant high-risk lineages for CRAB and CRKP.

Main Results:

• Incidence of carbapenem-resistant Acinetobacter baumannii (CRAB) and carbapenem-resistant Klebsiella pneumoniae (CRKP) is increasing, primarily through hospital-acquired infections.
• Carbapenem-resistant Pseudomonas aeruginosa rates are stable, while methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterobacter faecium are decreasing.
• Dominant high-risk lineages, CC92 for CRAB and ST11 for CRKP, mediate the spread of these resistant organisms.

Conclusions:

• Rising CRAB and CRKP pose significant challenges to the Chinese healthcare system.
• Addressing MDROs requires rethinking strategies, coordinated actions, capacity building, behavioral changes, and context-specific research.
