目的 探讨专项调查重点科室医务人员手卫生依从性及知识知晓情况结合院感信息系统在降低医院感染中的应用效果。方法 选取2018年1月—2020年12月本院重点科室收治的患者527例,根据入院时间进行分组,对照组采取常规院感管理,观察组采取基于院感信息系统的管理方式,并对重点科室的100名医务人员手卫生依从性及相关知识知晓情况进行专项调查,比较2组医务人员手卫生依从性、手卫生知识知晓程度及医院感染率的差异。结果 观察组医务人员执行各项操作的手卫生依从性、手卫生知识评分均高于对照组(P<0.05);观察组患者医院感染率低于对照组(P<0.05)。结论 采用专项调查重点科室医务人员手卫生依从性及知识知晓结合院感信息系统,能有效提高医务人员的手卫生依从性及相关知识知晓程度,降低医院感染的发生风险。

Objective To discuss the effect of applying special investigation on the hand hygiene compliance and knowledge of medical staff in key departments combined with nosocomial infection information system in reducing nosocomial infections. Methods A total of 527 patients admitted to the key departments from January 2018 to December 2020 were selected, and were grouped according to the time of admission.The control group received routine nosocomial infection management, and the observation group received the management based on nosocomial infection information system.A special survey of hand hygiene compliance and related knowledge was carried out on 100 medical staff in those department, and the differences in hand hygiene compliance, hand hygiene knowledge and nosocomial infection rates between the two groups were compared. Results The hand hygiene compliance and hand hygiene knowledge scores of the medical staff in the observation group were significantly higher than those in the control group (P<0.05). The infection rate of observation patients was lower than control patients (P<0.05). Conclusions The use of special survey on hand hygiene compliance and knowledge of medical staff in key departments combined with nosocomial infection information systems can effectively improve medical staff's hand hygiene compliance and related knowledge, reduce the risk of nosocomial infections, which is worthy of promotion.

目的 调查重症监护病房(ICU)医院感染的常见细菌分布及耐药性变化,为合理使用抗生素和医院感染的预防控制提供相关科学依据。方法 回顾性分析医院2007—2011年ICU收治的381医院感染患者感染菌株分布特点及耐药性情况。结果 ICU医院感染常见菌株主要来源于痰液标本,占78.2%,其次是血液。381 株临床分离菌中共检出革兰阴性杆菌262 株、革兰氏阳性球菌70例和真菌49例,分别占68. 8%、24.9%和占17.4%。革兰阴性杆菌中鲍氏不动杆菌(24.7%)、肺炎克雷伯氏杆菌(10.8%)、铜绿假单胞菌(9.2%)排前三位。其中除碳青霉烯类药物及抑酶制剂,鲍氏不动杆菌对其余抗菌药物耐药率均＞40%。革兰氏阳性球菌以金黄色葡萄球菌为主。对青霉素、庆大霉素、红霉素的耐药率均＞50%。结论 呼吸道仍是ICU最常见的感染部位。病原菌以革兰阴性杆菌为主,且对常用抗菌药物的耐药率逐渐升高,临床应加强抗菌药物规范使用,避免耐药菌株的产生。

Objective To investigate the distribution and drug resistance of pathogens in intensive care unit(ICU)causing nosocomial infections so as to provide scientific basis for antibiotic adoption and the prevention and control of nosocomial infections. Methods The specimen sources and the clinical distribution of the 381 pathogens isolated from 2007 to 2011 were retrospectively analyzed. The drug resistance was observed in ICU that causing nosocomial infections. Results The sputum was the major specimens source in ICU, accounting for 78.2%. Of the 381 pathogens causing nosocomial infections in ICU, the 262 gram-negative bacilli (68.8%), 70 gram-positive cocci (24.9%),and 49 fungi (17.4) were isolated, Among gram-negative bacilli the top three were acinetobacter baumannii (24.7%), klebsiella pneumonia(10.8%),and pseudomonas aeruginosa (9.2%). The drug resisitance rate of baumannii to antibiotics were more than 40%,beside carbapenem and B-Lactamaseinhibitors. The main gram-positive cocci of causing nosocomial infections was saphylococcus aureus in ICU. The drug resisitance rate of S. aureus to penicillin, erythromycin and gentamicin were higher than 50.0%. Conclusion The main distribution area of nosocomial infections was the respiratory tract and the gram-negative bacilli were the common pathogens in ICU. It was benefit to avoid presenting of drug resistant strain, and antibiotics should be reasonably used in clinic.
