Objective To analyze morbility，risk factors，etiology，treatment and outcome of nosocomial pulmonary fungal infections in respiratory intensive care unit（RICU）.Methods Forty-seven respiratory RICU patients with nosocomial pulmonary fungal infections between July 2000 and June 2005 were retrospectively analyzed.Results All of the 47 cases were clinically diagnosed as probable nosocomial pulmonary fungal infections，with the morbidity of 10.8% significantly higher than general wards（1.8%，Plt;0.005）.COPD and bacterial pneumonia were the major underlying diseases of respiratory system with a percent of 38.30% and 36.17%，respectively.Forty-one patients (87.2%) had risk factors for fungal infections.Compared with general wards，the proportion of Aspergillosis was higher in RICU without significant difference (Pgt;0.1)；the proportions of Candida glabrata and Candida tropicalis were higher too，but that of Candida krusei was relatively low.The effective rate of antifungal treatment was 79.1% and fluconazol was the most common used antifungal agents.The mortality of fungal infection in RICU was higher than that of general wards but without significant difference（Pgt;0.1）.Conclusion The morbidity of nosocomial pulmonary fungal infection in respiratory RICU is higher than that in general wards.The proportions of infection caused by Aspergilli and some Candida resistant to fluconazol is relatively high.Early and effective treatment is needed in these patients considering the poor prognosis.
Objective To investigate the prognostic factors and hospitalization cost in patients diagnosed as central line-associated bloodstream infection( CLABSI) in intensive care unit( ICU) .Methods A retrospective study was made to investigate the CLABSI epidemic data in ICU from June 2006 to June 2009. Clinical and physiological parameters were summarized and compared between these patients, which were divided into two groups based on the clinical outcome. Meanwhile, events including blood transfusion,mechanical ventilation, as well as cost of hospitalization were also reviewed. Logistic regression method was introduced to investigate the potential prognostic risk factors. Results There were 49 patients were diagnosed as nosocomial CLABSI, in which 19 cases( 38. 8% ) died in the hospital and 30( 61. 2% ) weresurvival. In univariate analysis, differences in body temperature, central venous pressure, acute physiology and chronic health evaluation( APACHEⅡ ) score, blood transfusion amount, pH value, D-dimer, blood serum alanine transarninase, blood urea nitrogen level, serumcreatinine, serumpotassiumbetween the survivors andthe non-survivors were significant( P lt;0. 05) . However, no significant differences were observed between the two groups in in-hospital days, ICU days and hospitalization cost ( all P gt; 0. 05) . With multiple logistic regressions, higher APACHEⅡ score( OR 0. 78; 95% confidence interval: 0. 66-0. 94; P = 0. 007) , APTTlevel( OR 0. 87; 95% confidence interval: 0. 77-0. 98; P = 0. 026) and serum potassium( OR 0. 09; 95% confidence interval: 0. 01-0. 80; P = 0. 031) were independent predictors of worse outcome. Conclusions Disease severity and coagulation situation may directly predict the prognosis of nosocomial CLABSI patients.But current investigation did not demonstrate significant differences in ICU length of stay and respective cost between the CLABSI patients with different prognosis.
医院感染是指住院患者在医院内获得的感染,包括在住院期间发生的感染和在医院内获得出院后发生的感染。重症加强治疗病房( ICU) 是医院感染的高发科室, 其中又以肺部感染最为常见, 导致患者死亡率增加及治疗成本上升。随着医疗技术的发展, 器官移植、有创检查及治疗手段的不断推广, 以及广谱抗生素、糖皮质激素和免疫抑制剂在临床治疗中的广泛应用, 下呼吸道感染病原菌的种类不断发生变迁, 由多重耐药菌( MDR) 及真菌引起的感染不断增多, 成为下呼吸道感染的主要病原菌之一。在大多数情况下, 这类条件致病菌在合适的部位定植而不引起感染, 当机体因各种因素造成的抵抗力下降、菌群失调或天然屏障结构破坏时可引起感染发生。 由于定植菌的致病性是相对的, 临床上无法通过患者的临床表现经验诊断至属或种, 实验室亦无法单纯依赖培养鉴定技术确定其是感染病原菌还是定植菌。在呼吸机相关性肺炎( VAP) 患者中, 下呼吸道的真菌定植率较高, 但真正出现真菌性肺炎的患者比例并不高, 以致对患者的结局无显著影响。如果仅仅根据真菌定植结果制定治疗方案就容易造成抗真菌药物的过度使用。因此, 判断肺部感染的病原学是定植还是感染成为目前医院感染治疗中的难点问题之一。
Objective To investigate on the epidemiologic characteristics of nosocomial infection in surgery departments of general hospitals by analyzing the data collected from documents which were published in recent years, so as to provide references for the construction of precautionary system model. Methods Applying comprehensive search strategies, we searched various electronic databases as CBM (1978 to 2008), CNKI (1912 to 2008), VIP (2001 to 2009) and WanFang Data (2001 to 2009). MeSH terms and/or text words included: nosocomial infections, cross infection, hospital infection, prevent and control. Data from top and second grade hospital were included in this analysis. Results Sixty four articles and a total of 1 990 929 inpatients were included. Results showed: average nosocomial infection rate was 4.46%; the total rates of medicine department and surgery department were 23.28% and 17.33% respectively and no significant difference was found between the two departments; the infection rates of G– and G+ germ were 47.71% and 21.31% respectively; the rates of average antibiotics use was 60.59% and the rate of missing report was 12.42%. Noscomial infection was related to season change and the wave peak was from February to May. Conclusion Most of the included studies were retrospective studies and cross-sectional studies. The type of data was inconsistency and incomplete, causing weak strength of evidence. High missing rate of reports makes the precautionary model hard to build in future.
Objective To survey the current situation of the sharp injury in medical workers, and to provide scientific evidence for the prevention and protection of sharp injury. Methods Through applying the questionnaire of sharp injuries designed by Zhongshan Hospital, Shanghai Fudan University, 10% of the workers in all departments of West China Hospital of Sichuan University were selected as respondents according to their job categories. The main contents of the survey included the general information of respondents, reporting after sharp injuries, training participation, and the exposure sources, operations, premises and equipments related to sharp injuries over the past one year.Results Of 840 questionnaires distributed, 100% were valid. The ratio of male was 23% while the female was 72%. There were 50.20% of all respondents who once got injured, and 75% of the respondents having the history of sharp injury worked less than 10 years. The nurses, house keepers and physicians were in the top three positions of suffering from sharp injury; and the operating room was ranked as the highest risk department for sharp injuries. The known haematogenous exposure sources were 69 cases of hepatitis B, 19 syphilis, 6 hepatitis C, and 3 HIV. There were 62% of the respondents who had ever attended related training, and only 11.61% of the injured respondents reported their sharp injuries. Conclusion The incidence rate of the sharp injury is high, but the report rate is low. The operating room is the high risk department, and nurses, house keepers, and physicians are the high risk population for sharp injuries. The prevention and protection and training for sharp injury in target departments and population should be strengthened.
