肛肠外科老年住院手术患者医院感染的危险因素

Risk factors for nosocomial infection in elderly hospitalized patients of anorectal surgery department

目的利用Logistic回归探讨肛肠外科老年住院手术患者医院感染的危险因素。方法选择2018年1月-2020年1月景德镇市第二人民医院肛肠外科收治的老年患者859例的资料进行回顾性分析,描述患者的医院感染情况、发生医院感染患者的标本病原体培养结果。利用Logistic回归探讨肛肠外科老年住院患者医院感染的危险因素。结果859例患者中共有135例发生医院感染,感染率为15.72%。在发生感染的患者中,以手术切口感染的构成比最高,共67例,占49.63%。135例患者的标本共培养出病原菌147株,革兰阴性菌93株,占63.27%,革兰阳性菌48株,占32.65%,真菌6株,占4.08%。大肠埃希菌的比例最高,共39株,占26.53%。年龄、性别、体质量指数(BMI)、病程、手术时间、使用抗菌药物种类,是肛肠外科老年住院患者出现医院感染的影响因素(P<0.05)。结论肛肠外科老年住院患者发生医院感染的情况比较严重,需要采取针对性的措施进行合理干预。

OBJECTIVE To explore the risk factors for nosocomial infection in the elderly hospitalized patients of anorectal surgery department by means of logistic regression.METHODS The data of 859 elderly patients who were treated in anorectal surgery department of the Second People’s Hospital of Jingdezhen from Jan 2018 to Jan 2020 were retrospectively analyzed,the prevalence of nosocomial infection and result of culture of specimens were described,and the logistic regression analysis was performed for the risk factors for nosocomial infection in the elderly hospitalized patients of anorectal surgery department.RESULTS Of the 859 patients,135 had nosocomial infection,with the infection rate 15.72%.Among the patients with infection,the patients with surgical incision infection were dominant,accounting for 49.63%(67 cases).A total of 147 strains of pathogens were isolated from the specimens of 135 patients,93(63.27%)of which were gram-negative bacteria,48(32.65%)were gram-positive bacteria,and 6(4.08%)were fungi.Escherichia coli was the predominant species of the pathogens,accounting for 26.53%(39 strains).The age,gender,body mass index(BMI),course of disease,operation duration and type of antibiotic were the influencing factors for the nosocomial infection in the elderly hospitalized patients of anorectal surgery department(P<0.05).CONCLUSION The nosocomial infection is highly prevalent among the elderly hospitalized patients of anorectal surgery department.It is necessary to take targeted intervention measures.
