目的 了解医院外科患者手术部位感染的危险因素，以采取预防与控制干预措施，降低手术部位感染率。 方法 以回顾性调查方法对2011年1月－6月外科手术患者统计手术部位感染率；以前瞻性调查的方法对2012年1月－6月外科手术部位患者进行目标性监测。 结果 2011年1月－6月手术部位感染率为1.01%，2012年1月－6月手术部位感染率为0.63%，两者比较，差异有统计学意义（P＜0.05）。患者年龄、手术类型、手术时间、手术性质是手术部位感染的高危因素。 结论 实施目标性监测，加强危险因素管理，采取干预措施，能有效降低外科手术部位感染率。
目的 分析外科手术部位感染率过低的原因，掌握手术部位感染诊断标准，减少医院感染漏报，及时发现医院感染流行趋势，采取控制措施，防止医院感染暴发。 方法 选择开展较多、手术部位一旦发生感染对患者安全威胁性较大的手术：包括胆囊切除或（和）胆管手术，结肠、直肠切除术，阑尾切除术，疝手术，乳房切除术，剖宫产，子宫切除术及附件切除术，全髋关节置换术，食道贲门手术，腰椎间盘摘除术，监测时间为2011年1月1日－6月30日及2012年1月1日－6月30日，共监测1 180例手术，对手术部位感染率进行对比分析。 结果 2011年半年监测手术部位感染率1.99%，调整感染率4.74%；比国内报道低6～9倍；通过分析原因，对医院感染诊断标准再培训、加强病原微生物送检等，2012年半年监测手术部位感染率4.68%，调整感染率32.12%；与2011年比较差异有统计学意义（χ2=141.841，P=0.000）。 结论 手术部位感染率偏低的原因是医生漏报所致；采取整改措施后，提高了手术部位感染的识别能力，减少了漏报，对及时发现医院感染暴发具有重要意义。
ObjectiveTo explore the risk factors for and preventive measures of orthopedic perioperative surgical site infection. MethodsWe retrospectively analyzed the clinical data of 2 752 cases of orthopedic surgery performed from January 2010 to December 2012. The risk factors for such infection were analyzed and certain preventive measures were put forward. ResultsA total of 97 patients were infected with a surgical site infection rate of 3.52%. The surgical site infection was closely related to ages, basic diseases, surgical site, types of incision, preoperative hospital stay, operative time, urgent elective surgery, the use of antibiotics, medical staff hand hygiene and other factors, of which the rate of infection after amputation was the highest, reaching 23.81% (20/84). ConclusionMaking full preparations before operation, strengthening medical staff's hand disinfection, prophylactic antibiotics, good precautions and regulations in operation, and nursing meticulously after operation can be taken to prevent and reduce surgical site infection in orthopedic operation patients effectively.
ObjectiveTo analyze the relevant factors for surgical site infection. MethodsA total of 677 cases of surgery in one hospital from July 1 to December 31 in 2012 were surveyed (not including implant and cardiac intervention surgeries), which were divided into different groups according to the preoperative incision contamination level, and the postoperative healing of incisions were observed closely. After the patients were discharged, we investigated the situation of incisions by phone or periodic review, and forms were filled in on schedule. ResultsBy follow-up evaluation of the 677 cases, the incisions in 12 cases were infected and the infection rate was 1.77%. Polluted and infected (14.28%, 30.76%) incisions caused more infection than the clean and clean-polluted incisions (0.00%, 0.59%). The patients who stayed in hospital for 4 or more than 4 days before surgeries (infection rate was 4.55%) took more risk of infection than the patients whose preoperative time in hospital were 2-3 days (infection rate was 0.60%) and 1 or shorter than 1 day (0.68%). Perioperative use of antibiotics for longer than 72 hours will increase the risk of incision infection than those within 48 hours (7.69%, 0.00%; P=0.002). ConclusionSurgical site infection is related to the incision type. Shortening the preoperative in-hospital time will reduce the risk of infection. Long time use of antibiotics in perioperative period cannot prevent the postoperative infection effectively, but may increase the risk of infection.
ObjectiveTo probe into the risk factors for postoperative surgical site infections in the Department of Cardiothoracic Surgery, and put forward correspondent preventive and treatment measures. MethodA total of 360 patients who underwent operations between February 2011 and March 2013 were the study subjects. The age, sex, basic diseases, surgical time, hospitalization time, surgical implants, and incision category were recorded carefully, and were analyzed for their correlation with surgical site infections. ResultsThere were 27 cases of surgical site infections with an infection rate of 7.50%. Age, hospitalization time, surgical time, basic diseases, surgical implants and incision category were risk factors for surgical site infections (P<0.05). ConclusionsBased on the analysis of risk factors for surgical site infections, we can help patients recover as early as possible by taking preventive measures beforehand.
ObjectiveTo study the effects of PDCA cycle in the control of surgical site infection (SSI). MethodsA total of 1 761 surgeries between January 2012 and December 2013 were chosen to be monitored. PDCA cycle was used as a tool of total quality management evaluation to enhance the control of SSI. ResultsAfter 2 to 4 cycles of PDCA, the preventive medication rate of ClassⅠ operation incision was decreased significantly (χ2=309.513，P<0.001) and the postoperative incision infection rate did not change significantly (χ2=1.474，P=0.669). ConclusionUsing PDCA cycle can increase SSI management level and quality significantly and total quality management can be operated effectively.
ObjectiveTo study the present situation of hospital orthopedic surgery incision infection, in order to provide the basis for further intervention. MethodsProspective investigation combined with retrospective investigation method was adopted in our study to perform a statistical analysis on orthopedic surgery incision infections among 545 patients in our hospital between January and December 2012. ResultsDuring the one year of follow-up, there were 10 cases of surgical incision infection among all the 545 patients, with an infection rate of 1.83%. The infection rate of class-Ⅰ incision was 0.46%, of class-Ⅱ was 5.13%, and of class-Ⅲ/Ⅳ was 12.12%, and the Cochrane-Armitage trend chi-square test showed significant trend among them (χ2=28.273, P<0.001). Based on different operation risk index, patients with index 1, 2, 3 had a surgical site infection rate of 0.82%, 2.60%, and 18.75%, respectively. The higher the index, the higher the surgery incision infection rate, and the trend was statistically significant (χ2=12.916, P<0.001). The infection rate was 1.43% for elective surgical procedures, and was 3.15% for emergency surgery, but there was no significant difference (P>0.05). ConclusionOrthopedic surgery has a high-risk surgical site infection rate, and incision classification and surgical risk index have statistical correlation with the incidence of hospital infection. In order to ensure the security of patients and reduce medical disputes, we should pay close attention to orthopedic surgery infection.
ObjectiveTo investigate the risk factors for surgical site infection (SSI) in patients after colorectal surgery, in order to provide a basis for regulation and implementation of preventive measures against SSI. MethodsFrom February to December 2012, a targeted surveillance on surgical site infection of "colon resection" and "rectum resection" surgery patients in the Department of Gastrointestinal Surgery was carried out. We analyzed the monitoring data, and explored the occurrence of postoperative SSI. At the same time, by case-control study, both single and multiple regression logistic analyses were performed on the 12 variables such as hypertension, diabetes mellitus duration during operation, America Society of Anesthesiologists score, grade of incision and so on to analyze the risk factors for SSI. ResultsAmong the 535 patients who underwent colorectal resections, 44 had SSI with an infection rate of 8.22%. Multiple logistic regression analysis showed that the length of hospital stay[OR=1.070,95%CI(1.033,1.109), P<0.001]and emergency surgery[OR=6.320,95%CI(1.932,20.669),P=0.002] were independent risk factors for SSI after colorectal resections. ConclusionThere are many risk factors for SSI after colorectal surgery. Through the implementation of targeted surveillance, we can find the main risk factors, which provides a basis for the regulation and implementation of intervention measures against SSI.
