Abstract:
ObjectiveTo study the multilocus sequence characteristics of polymerase chain reaction (PCR) map of 3 isolates of methicillinresistant Staphylococcus aureus (MRSA) which carried a new staphylococcal cassette chromosome mec(SCCmec) .MethodsIn the previous PCR typing study on 58 MRSA isolates, 3 (5.17%) were found to carry a new SCCmec multilocus sequence containing 5 bands, which were band A,F,H, B and M. The above amplified products were sequenced, and then compared with the sequences of SCCmec type saved in the international GenBank and the Basic Local Alignment and Search Tool (BLAST).ResultsThe homology between the detected sequence and the known sequence was over 97%.ConclusionIt’s a new PCR pattern of multilocus sequence of SCCmec type, and maybe the recombinant of conventional SCCmec type I,II and III, which is not only a different PCR pattern, but also has multilocus mutation.

Abstract:
ObjectiveTo investigate occupational exposure to blood among health care workers (HCWs) in Guangdong province, and provide scientific basis for developing preventive measures.MethodsA crosssectional survey on sharps injuries among HCWs at 39 hospitals in Guangdong province in June 2011 was conducted through questionnaires.ResultsA total of 32 617 questionnaires were distributed, and 32 297 (99.02%) were responded; and 32 007(99.10%) questionnaires were available for analysis. 1 460 HCWs had suffered 1 909 times of sharps injuries, and the incidence was 4.56% , the injury episode rate was 5.96%; the average number of injury per month was 0.06/person. 1 495 (4.67%,1 495/32 007) injury episodes were caused by contaminated sharps; contaminated sharps injuries accounted for 78.31%(1 495/1 909) of total sharps injuries, and 61.67%(922/1 495) of which could trace to the exposure sources, while 38.33%(573/1 495) couldn’t determine the infectivity. Among bloodcontaminated devices, 81.71%(67/82) were hepatitis B exposure, 14.63% (12/82) were syphilis exposure; 3.66%(3/82) were hepatitis C exposure, there was no HIV exposure. The locations where sharps injuries occurred mostly were general wards (47.72%) and operating rooms (20.27%); the procedures involved in high injury rates were dispensing(15.92%) , medical waste disposal (12.78%), and syringe needle removal(12.21%); the main medical devices that caused sharps injuries were disposable syringe needles(35.99%), scaple needles(19.43%) and suturing needles(13.41%). HCWs’ training rate of knowledge about bloodborne occupational exposure was 93.25%.ConclusionSharps injury is the main professional factor that cause bloodborne diseases. In order to reduce the risk of injuries caused by occupational exposures, medical institutions should establish corresponding organization and rules, and HCWs should standardize preventive and control behavior towards occupational exposures.

Bacterial culture results of heparin sodium sealing solution , disposable syringes, and environmental samples were all qualified, only 1 tube of used heparin sodium sealing solution (all patients shared this tube) isolated B. cepacia, antimicrobial susceptibility test result was the same as B. cepacia from patients’ blood culture result. Measures were taken promptly, the deep venous catheters were removed, and antiinfective therapy was adopted ,none of the patient isolated bacteria from blood cultures 7 days later, and no identical case emerged again. ConclusionContamination of heparin sodium sealing solution by B. cepacia is the cause of this CRBSI ,through active treatment , infection is controlled.

ObjectiveTo investigate the point prevalence of healthcareassociated infection(HAI) and communityassociated infection (CAI) in patients in a hospital, so as to provide basis for the prevention and control of HAI.MethodsBy combination of bedside survey and medical record reviewing, all patients who were hospitalized between 0:00 and 24:00 o’clock of September 26, 2011were investigated.Results1 331 patients should be surveyed, 1 309 (98.35%) were actually surveyed. 237 patients were infected,57 (4.35%) of whom developed 60 episodes(4.58%) of HAI ; 181 (13.83%) of whom developed 183 episodes (13.98%) of CAI; 1 patient developed both HAI and CAI. The top three infection sites of HAI were lower respiratory tract(48.33%), organ space (16.67%) and urinary tract (8.33%). CAI were common in the following three departments : department of respiration medicine(84.44%), pediatric department(71.43%) and intensive care unit(50.00%);the main infection sites of CAI were lower respiratory tract(45.36%) and skin and soft tissue(15.30%). A total of 65 pathogenic strains were isolated, 33 of which were HAI isolates and 32 were CAI isolates; Pseudomonas aeruginosa, Acinetobacter baumannii, Escherichia coli and Klebsiella pneumoniae altogether accounted for 72.73%(24/33) of HAI and 78.13%(25/32)of CAI .The daily antimicrobial usage rate was 27.43%(359 cases), 52.92% of which were for prophylactic use, 43.45% for therapeutic use, and 3.62% for both prophylactic and therapeutic use; 88.02% of antimicrobial application were single dose, and 11.98% were the combination of two agents. Pathogen detection rate was 61.54%(104/169).ConclusionSurvey of point prevalence of infection is helpful to the realizing of the current state of HAI and CAI and application of antimicrobial agents, and is beneficial to the target surveillance of infection.

Abstract:
To evaluate the disinfectant efficacy of ethanol on transparent PVC endotracheal tube , as well as the best replacement time. MethodsPhase I: 58 patients with transparent PVC endotracheal tube between April and July 2011 were selected , the concentration and bacterial count of ethanol used for immersion disinfection of transparent PVC endotracheal tube were detected at different time point (upon opening of the new ethanol and 12, 24, 48 and 72 h after opening ), ethanol was used continuously for 72 h . Phase II: 46 patients with transparent PVC endotracheal tube between July and November 2011 were selected and divided into experimental group (new process: immersion tank and ethanol were changed every 48 h) and control group (former process: immersion tank and ethanol were changed every 24 h), the frequency of change, manpower, cost and incidence of infection within one month between two groups were compared .ResultsThe difference between ethanol upon opening and 12, 24 as well 48 h after opening were not statistically significant (all P>0.05);72 h after opening, ethanol concentration was significantly lower than the newly opened ([71.82±0.77]%vs [72.98±0.83]%,t=17.60,P<0.05). Disinfection efficacy of ethanol at different time points all met the required standards. Cost of experimental group was significantly lower than the control group (CNY[56.70±9.30] vs CNY[178.20±4.70]), and manpower was also significantly lower than the control group ([37.20±5.80] persontime/month vs [120.30±6.70] persontime/month,all P<0.05); Incidence of infection was not statistically significant between two groups(13.04% vs 17.39%,t=0.17,P>0.05). ConclusionEthanol immersion disinfection is a effective, low cost, easy operation and safe disinfection method, ethanol can be used continuously for 48 hours before changed if ethanol tank is sealed well and with low opening frequency.

目的了解某院泌尿外科门诊患者抗菌药物使用情况。方法随机选择该院2011年3月份3天泌尿外科门诊患者276例,对其病历进行回顾性调查。结果276例泌尿外科门诊患者抗菌药物使用率为85.51%(236/276),其中静脉输液给药226例,占95.76%。联合用药占87.29%,其中二联用药194例,三联用药12例;二联用药以奥硝唑+甲磺酸帕珠沙星(55.15%)和奥硝唑+左氧氟沙星(21.65%)为主。奥硝唑和甲磺酸帕珠沙星应用频率最高,分别占43.17%和25.99%。泌尿外科门诊抗菌药物使用构成比居前2位的疾病为前列腺炎(48.31%)和术后包皮畸形(22.03%);其次为包皮过长、包皮环切术后、包茎、早泄、龟头软疣非细菌感染疾病用药,合计40例,占16.95%;尿道炎、龟头炎及泌尿系感染用药占12.71%。结论该院泌尿外科门诊存在抗菌药物使用不合理现象,需强化规范抗菌药物的使用。

Abstract:
目的了解某院不同科室医务人员锐器伤发生现状,为制定预防措施提供依据。方法2011年7月,对该院重症监护室(ICU)、急诊科、外科、内科、手术室、供应室工作满4年的340名医务人员进行回顾性问卷调查。结果共发放问卷340份,收回有效问卷332份,有效率97.65%。医务人员锐器伤发生率为38.25%(127/332),其中医生为30.00%(30/100),护士为41.81%(97/232),护士锐器伤发生率显著高于医生(χ2=4.13,P<0.05)。不同科室医务人员锐器伤发生率不同,差异有统计学意义(χ2=49.29,P<0.01),其中急诊科医务人员锐器伤发生率最高(73.08%)。结论医务人员发生锐器刺伤的概率较高,应强化职业安全防范意识,规范操作行为,最大限度地减少职业伤害,实现暴露后零感染目标。

目的开展手卫生在职教育活动,强化医务人员手卫生意识,进一步规范医务人员手卫生的执行。方法对某院2011年12月在岗的工作人员开展以“预防院感,从手开始”为主题的在职教育活动。活动形式包括现场承诺签名,门诊、住院大厅设置宣传画展板,院内局域网上传学习手卫生知识及技能培训,洗手明星理论与操作竞赛。结果此次在职教育活动参加总人数达622人,包括医生、护士、药剂、检验、行政后勤人员等。评选出五星、四星、三星洗手明星科室(分别为1、2、3个)和个人(分别为5、10、15人),其中洗手为五星的明星科室是耳鼻咽喉科,5位五星的明星个人分别来自妇产科、烧伤泌尿外科、耳鼻咽喉科、骨科、功能科室。结论通过开展手卫生在职教育活动,使全院各级各类人员正确理解了手卫生规范要求,改变了错误的手卫生观念,营造出良好的手卫生氛围,使手卫生受到全员重视。

Abstract:
医疗器械使用后,应进行彻底地清洁处理,去除附着在上面的血液、黏液和体液等有机物,这是预防和控制医院感染,保证医疗安全的重要环节。器械清洁方法正确与否,清洗质量合格与否,清洗后的维护和保养及如何通过物理和化学方法将器械上的有机物、无机物和微生物清除到安全的水平,对保证灭菌效果和控制交叉感染具有重要的作用[1]。在所有环节中,器械清洗是基础和前提,如果清洁不彻底,医疗器械上残留的有机物会在微生物的表面形成一层保护层,妨碍消毒灭菌因子与微生物接触或延迟其作用,影响消毒灭菌效果。因此,器械清洗质量是否合格尤为重要。
