The Study Of Hospital Infectious Risk Factors And Intervention Measures In High Risk Departments

Objective:Investigation of the hospital infection about susceptible population, susceptible parts and related factors in order to prevent and control hospital infection through implementing effective intervention.The hospital infection rate in2009had significantly reduced comparied with2009. The incidence of the infection in lung, respiratory tract infection, wound infection, viral hepatitis infection and other parts of infection were significantly reduced with the improvement of various hospital infection systems, norms and measures, following the executive force of clinical departments.Methods:Randomly choiced departments which liable to develop the nosocomial infection, ICU、 pediatric department、neurology department、oncology and multiple surgical high-risk department, such as brain surgery, thoracic surgery, bone surgery, etc.we monitored for the situation of nosocomial infection continuously Data from the situation of infection in the year of2008and2009were analyzed Statistically. According to the site of infection we classified and looking for the law of infection. Compared between taken corresponding infection control measures of nosocomial infection situation(2009)and before (2008), observed the change of incidence of nosocomial infection and compared the incidence in different departments to find the risk factors’ characteristics and differences of nosocomial infection, which can guide the hospital infection prevention work.Choose detection index:incidence of nosocomial infection,, the site and type of infection, presence of complications and so on., the change of each index after intervention. Results:1. The comparison of hospital infection rates between2008and2009. The cases monitored in hospital in the recent two years were26707person-times, finding that the hospital infection cases were971and the hospital infection rate was4.22%which revealed the overall trend of present down slowly. The hospital infection rate in2009below that in2008and the difference between them had statistical significance.2. The difference of high-risk infection departments in hospital. The top three infection rates in the departments were ICU, burn urology department and nephrology department respectively. Their infection rates had significant difference.3. The analysis of ages and gender about hospital infection.48771patients grouped by age were analyised and comparied. The result showed that the difference had statistical significance. The highest incident group were the1-10interval, followed by the0-1interval and finally the10-30interval.4. The analysis of the hospital infection by infectious sites. According to the classfication through the infected sites, the hospital infection were mainly respiratory tract infection making up16.37%, including upper respiratory tract (14.32%), the gastrointestinal tract (12.7%), urinary tract (11.84%), skin soft tissue (9.99%), peritoneal cavity (9.37%), chest (8.75%), blood (4.84%) and oral (7.31%).5. The analysis of hospital infection according to season packet. The third quarter infection rate was the highest at2.30%and the lowest incidence of infection was1.19%in the fourth quarter.The hospital different season nosocomial infections have significant difference.6. Disinfection effective testing analysis. From2008to2009the data of bacterial test in hospital operating room, ICU neurosurgery, urology department, emergency department, clinical laboratory, supply room, air, staff hands, objecttive surface and aseptic goods collected, analysied and classflied. All kinds of goods disinfection and sterilization effiective rate was at96.82%. Among them, the aseptic goods disinfectant and sterilization agent high-risk area salmonella and festering bacteria disinfection sterilization effects were at100%, medical staff hand disinfection percent of rate was at91.73%, surface disinfection percent of pass was at94.18%and the air disinfection percent of pass was at97.56%.Conclusion:The factors in hospital infection are divided into subjective and objective factor.Subjective factor:1. Medical staff in hospital does not fully understand the importance of hospital infection, and the implementation is not strict in disinfection and isolation system and aseptic technique. The compliance principle of antibacterial drug use is low, The process of diagnosis and treatment of hospital infection controlling executive validity is not enough.2. The monitoring doctors and nurses in the hospital should screen the hospital infection of high-risk patients timely so that providing effective intervention as soon as possible is the key to reduce the incidence of hospital infection.objective factor:1. The number of patients used invasive methods of diagnosis and treatment is increasing year by year.2.The number of patients who use immunosuppressants is at sustained growth.3.With the development and universal application of antibacterial drugs, the patients ocurring normal flora imbalance and the drug resistant strains are increasing.4. The visiting peopie is increasing year by year and the serious pollution in the environment is also getting worse.
