北京市某医院医疗器械致院内感染的危险因素分析

Analysis of Risk Factors of Nosocomial Infection Caused by Medical Instruments in a Hospital of Beijing City

目的:研究医疗器械致院内感染的危险因素并对其针对性预防措施予以分析。方法:选取2014年4月-2017年4月北京市某医院发生医疗器械相关血液感染的患者102例(观察组)和未发生医疗器械相关血液感染的患者102例(对照组)为研究对象。对医疗器械致院内感染相关危险因素进行分析,比较两组空气生物检测、物表生物检测以及医务人员手卫生检测合格率,两组院内感染发生率及医务人员对医疗器械的满意度。结果:观察组空气生物检测、物表生物检测以及医务人员手卫生检测合格率均高于对照组(均P<0.05)。经Logistic回归分析,空气生物检测不合格、物表生物检测不合格以及医务人员手卫生检测不合格均是影响医院医疗器械致院内感染的独立危险因素(均P<0.05)。观察组院内感染发生率低于对照组(P<0.05)。观察组医务人员对医疗器械的满意度高于对照组(均P<0.05)。结论:空气生物检测、物表生物检测以及医务人员手卫生检测不合格均可能诱发医疗器械致院内感染,通过针对性干预可有效降低院内感染发生率,同时提高医务人员满意度。

Objective: To study the risk factors of nosocomial infection caused by medical instruments and analyze its pertinent preventive measures. Methods: From April 2014 to April 2017, medical device related blood infections 102 patients was selected as observation group, and 102 cases with no blood infection were taken as the control group. The two groups with air biological detection, surface biological detection and medical staff hand hygiene detection qualified rate were compared, and the incidence and satisfaction of medical staff on medical infection were compared too. Results: The air biological detection, surface biological detection and medical personnel hand hygiene inspection qualified rate of observation group were significantly higher than the control group(all P <0.05). Logistic regression analysis showed that the air biological testing was not qualified, the biological examination of the surface was not qualified, and the hand hygiene inspection of medical staff was not qualified, which were the independent risk factors of nosocomial infection caused by hospital medical devices (all P <0.05). The observation group of the incidence of nosocomial infection was significantly lower than the control group( P <0.05). The observation group of satisfaction of medical staff on medical devices was significantly higher than the control group(all P <0.05). Conclusion: Air biological testing is not qualified, biological examination is not qualified, and medical staff's hand hygiene inspection is not qualified, which may induce hospital infection caused by medical devices, and targeted intervention can effectively reduce the incidence of nosocomial infection, and improve the satisfaction of medical staff.
