Abstract:
Objective To explore the effect of collaborative mode of adopting infection prevention and control(IPC)and antimicrobial stewardship(AMS)by medical institutions on reducing bacterial resistance.Methods Healthcare-associated infection(HAI)management and antimicrobial-related indicators,as well as multidrug-resis-tant organism(MDRO)detection rates of all hospitalized patients in a hospital from January 1,2015 to December 31,2022 were collected.The effectiveness of collaborative mode of IPC and AMS was evaluated.Results Compared with 2015-2016,the incidence of MDRO HAI in 2021-2022 decreased from 0.22％to 0.16％(P＜0.05),anti-microbial use density in hospitalized patients decreased from 48.48 to 42.17,antimicrobial use rate decreased from 49.45％to 45.21％(P＜0.05).The use rate of prophylactic antimicrobial agents in class Ⅰ incision surgery de-creased from 48.62％to 33.13％(P＜0.05).Compared with 2017-2018,pathogen detection rate before antimi-crobial therapy increased from 60.73％to 72.18％in 2021-2022(P＜0.05).Compared with 2015-2016,except the detection rate of vancomycin-resistant Enterococcus faecalis slightly increased in 2021-2022,detection rates of other common MDRO decreased,especially methicillin-resistant Staphylococcus aureus,carbapenem-resistant Acine-tobacter baumannii,carbapenem-resistant Pseudomonas aeruginosa,broad-spectrum β-lactamase-producing Kleb-siella pneumoniae,broad-spectrum β-lactamase-producing Escherichia coli and fluoroquinolone-resistant Escherichia coli,differences were all statistically significant(all P＜0.05).Conclusion The collaborative mode of IPC and AMS can effectively promote the rational use of antimicrobial agents,decrease the occurrence and transmission of MDRO,and decrease bacterial resistance.
