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.
ObjectiveTo explore the supervision and inspection mechanism of hospital-acquired infection management at hospital-level in order to promote continuous quality improvement of hospital-acquired infection control. MethodsInstead of inspecting hospital departments only by hospital infection control professionals, the clinical hospital infection control nurses were also involved in the two cross-inspections carried out respectively in September and December, 2013, which shared the same contents, methods, and the inspectors. According to standard procedures, on-site view and inquiry methods were adopted to check the implementation of the system and measures and the infection control knowledge among medical staff. Inspection results were written down to feed back to each department with a unified form. The problems found during the two inspections were classified to be analyzed and solved. The results of the two inspections were compared to understand whether the effect of continuous quality improvement can be achieved through cross-inspections and subsequent work. ResultsThe excellent rate of department and overall accuracy rate of the second inspection increased with statistical significance compared to that of the first inspection (χ2=619.902, P=0.000; χ2=40.347, P=0.000). Meanwhile, the correct rate of each module and infection control knowledge among all kinds of medical staff also increased compared with the first inspection with statistically significant differences (P<0.05). ConclusionLong-term mechanism of cross-inspection involving hospital infection control nurses should be established to facilitate the continuous quality improvement of hospital-acquired infection management.
ObjectiveTo investigate and analyze the antibiotic use in Sichuan Province. MethodsAntibiotic use of inpatients was investigated in 23 hospitals on the day of June 25, 2011. ResultsThe percentage of antibiotic use was 42.4% in the total 27 144 inpatients, the range of which was between 24.3% and 63.3% for each hospital. And 63.8% of the antibiotic use was for therapeutic purpose, and 72.2% used only one antibiotic drug. A total of 36.9% of the patients receiving antibiotic treatment for therapeutic use sent samples for pathogenic detection. With the increase of the size of the hospital (judged by the number of beds), antimicrobial drug utilization decreased with statistical significance (χ2=411.834, P=0.000). With the improvement of regional economic level (judged by per-capita GDP of each region), the hospital antimicrobial usage decreased with statistical significance (χ2=500.093, P=0.000). The three types of antimicrobial drug most frequently used were other β-lactam antibiotics, penicillin and third generation cephalosporin. ConclusionAntibiotic use is reasonable in Sichuan Province as a whole. However, it is necessary to reduce irrational use of antimicrobial agents continuously, and to strengthen the management of clinical antibiotic usage among inpatients.
ObjectiveTo analyze and discuss the importance of non-catheter-related hospital infection in intensive care unit (ICU). MethodA prospective target monitoring of all the patients in the general ICU was carried out from January 2011 to December 2013. The hospital infection cases grouped by infection types were analyzed with SPSS 17.0. ResultsA total of 5 364 patients were monitored, 455 of whom had hospital infections totaled 616 times. The hospital infection rate was 11.5%. The amount and constituent ratio of the catheter-related infections showed a declining trend year by year, while the non-catheter-related infections revealed an escalating trend year by year. In these 455 patients, the mixed infection group had the longest hospital stay, followed by the catheter-related infection group and the non-catheter-related infection group (P<0.05). The catheter-related infection group had higher crude mortality rate than both of the mixed infection group and the non-catheter-related infection group (P<0.017). ConclusionsNon-catheter-related infections which get higher and higher proportion in ICU hospital infections should be paid more attention to, while catheter-related infections which could prolong hospitalization and increase the risk of death in ICU patients, remain the focus of the target monitoring of hospital infection in ICU.
