Background Multidrug-resistant organisms (MDROs) may increase the risk of nosocomial infection and impose great economic burden on patients' families and society. So it is of great significance to analyze the status, especially hotspots of research on MDROs for further research. Objective To analyze the research hotspots of MDROs in China from 2000 to 2020. Methods CiteSpace and bibliometric methods were used to conduct a visualization analysis of studies related to MDROs included in CNKI database of China in recent 20 years, involving the regularity of growth, high-frequency keywords, evolution of research hotspots and so on. Results In all, 3 808 studies were included. The number of these studies published during 2000—2020 demonstrated an upward trend in general, and could be divided into five stages: low output (2000—2004) , slow growth (2005—2009) , rapid growth (2010—2015) , relatively stable growth (2016—2018) and further development (2019—2020) . A total of 221 nodes and 302 edges were found by keywords co-occurrence network analysis. And besides MDROs and multidrug resistance, the central value of other 10 of the top 20 most frequently used keywords was equal or over 0.10, including nosocomial infection, multiple drug-resistant bacterial infections, Pseudomonas aeruginosa, ICU, Escherichia coli, drug resistance, antibiotics, Klebsiella pneumoniae, drug sensitivity test, and intensive care unit. The keywords were clustered into 15 clusters by cluster analysis, mainly included the following four themes: multiple resistant strains, multidrug-resistant bacteria infection and prognosis, diseases leading to multiple drug-resistant bacteria infections, generation mechanism and prevention and control of MDROs. The highly cited burst-related words mainly were drug resistant strains, drug resistance, antibacterial agents, and integron from 2000 to 2013, but there were no burst-related words after 2013. Conclusion The number of studies about MDROs in China demonstrated an overall upward trend from 2000 to 2020, with nosocomial infection, antibacterial agents, key drug-resistant strains and integron as the research hotspots, but few of them were about surveillance of drug resistance.
