目的了解医院感染现状及抗菌药物使用情况,为预防与控制医院感染提供科学依据。方法采用横断面调查的方法,对2011年12月2日的住院患者进行医院感染现患率调查。结果调查住院患者985例,发生医院感染67例,现患率为6.8%;居前3位的科室为综合ICU、血液科和老年科,现患率分别为48.4%、25.0%和22.4%;感染部位居前3位的为下呼吸道、泌尿道和上呼吸道感染,分别占54.3%、21.7%和5.4%;病原菌检出以革兰阴性菌为主,占59.7%,其中铜绿假单胞菌居首位,占16.4%;调查日抗菌药物使用率为36.9%,治疗前病原菌送检率为78.7%。结论重点监控感染高危科室和易感因素,进一步加强抗菌药物使用的管理,可有效预防与控制医院感染的发生。
Objective To understand the current situation of nosocomial infection and the use of antibacterials in order to provide a scientific basis for the prevention and control of nosocomial infections. Methods The method of cross-sectional survey was used to investigate the prevalence of nosocomial infection in hospitalized patients on December 2, 2011. Results Among 985 inpatients, 67 were hospitalized and the prevalence rate was 6.8%. The top 3 departments were ICU, hematology and geriatric department, with prevalence rates of 48.4%, 25.0% and 22.4%, respectively. Infection sites The top three were lower respiratory tract, urinary tract and upper respiratory tract infections, accounting for 54.3%, 21.7% and 5.4% respectively. Gram-negative bacteria were the main pathogens, accounting for 59.7% of the total, of which Pseudomonas aeruginosa Bit, accounting for 16.4%; on the survey day antibacterial drug use rate was 36.9%, pre-treatment pathogenic bacteria delivery rate was 78.7%. Conclusions The focus of surveillance of high risk departments and susceptible factors, to further strengthen the management of antimicrobial use, which can effectively prevent and control the occurrence of nosocomial infections.
