Epidemiologic Studies On Hospital Infection In One Of General Hospitals Of Daqing

Nosocomial Infection is one of the important problems in the population health of the global hospitals, especially in the hospitalization people who are recuperating. It is also the important criteria to weight and value the level of hospital management and medical attendance. and its incidence which is an important indicator to evaluate the level of hospital management and medical attendance has drawn a wide attention among the medical profession all over the world . Nosocomial Infection was affected by several factors such as resources.and level , infection management of the hospital. The number of Outpatients and beds in the hospital is more than 170 man-time and 1066 respectively ,and the hospital can do heart ,kidney transplantation successfully and so on.Epidemiologic study on Nosocomial Infection is about pathogenic bacteria ,the distribution and link of infection, risk factors and so on .It provides scientific and accurate monitoring date as the basis of estimation ,controlling and management of the nosocomial infectionObjective: To learn about nosocomial infection actuality in Daqing oilfield general hospital, master the dynamic variation tendency of nosocomial infection for 4 years and analyse the risk factors. This paper is to explore the Infection management of general hospital from the perspective of health economics, analyze the economic losses, caused by nosocomial infection, and discuss the problems and solutions of the nosocomial infection management. According to the disciplinarian of hospital infections occurred , we may make a use of the relating theory, methods and technical measures to constitute an effective monitoring system.Methods:1. Monitoring data: investigate retrospectively all the infection monitoring cases that patients discharged from hospital from July 2004 to July 2008, the result is a total of 149219 case- times. Sum up cases of nosocomial infection during 4 years, describe the nosocomial infection distribution of the time,space and population,analyse the changes in the trend of characteristics of pathogens, the prevalence of drug-resistant strains and so on.2. Cross-sectional surveys: make the inventory survey of the in- patients'cases twice with a combination method of the beside survey and hospitalization survey.3. the case-control survey: with the pair matching , compare the health resource consumption of the nosocomial infection with that of the none nosocomial infection hospitals to evaluate the nosocomial infection from the perspective of health economics .Statistical Analysis : The data is input by the means of Epidate software to set up a database and analyzed with SPSS 13.0 software.Results: The survey result in 4 years indicated that the total incidence of the nosoeomial Infection was stabilized ,the incidence were from 2.5% to 2.8%, its case- times incidence were from 2.8% to 3.0%,and incidence density were from 2.6% to4.3%.The top 5 Infection sites were upper respiratory tract (46.8%), lower respiratory tract (21.8%), gastrointestinal tract (11.7%), urinary tract(6.2%) and deep surgical incision (3.7%).The top 5 Infection departments were neurological rehabilitation (9.2%), hematological (7.6%), traditional Chinese medicine(5.5%) and renal medicine (5.3 %).The prevalence of the nosoeomial Infection is significant higher than the incidence. The main Infection site was respiratory tract and the main Infection departments were medical and surgical. the top 5 medical methods usage rate were immunosuppressive,urinary intubation,chemical radiotherapy,biomotor. Due to the nosoeomial infection, hospitalization time were extended by 10.4 days per case on average. In comparison with the control group, the extra expenditure is 9286.0±23784.5 yuan per case on average, which was mainly spent on drugs, laboratory, materials ,treatment and disposal fees.Conclusion:1. nosoeomial infection rates total tended to be stable ,The main infection sites followed by high to low were upper respiratory tract , lower respiratory tract, gastrointestinal tract, urinary tract and deep surgical incision. Groups of age below 3 years or above 55 years are high risk for the nosoeomial Infection.nosoeomial infection rates as a result of the different departments vary ,The Internal medicine, pediatrics and surgery are the key departments for surveillance.2. The top5 factors those have close relationship with nosocomial infection were as follows: immunosuppressant, indwelling catheter., chemical radiothrapy, ventilator and venous incubation. The usage rate of antimicrobial agents higher than National Standard, the department of surgery had the higher use in it and There were phenomenons of long medicine and prophylaxis use antimicrobial agents.3. The prevalence of the nosoeomial Infection is significant higher than the incidence. The infection sites and departments distribution in the cross-sectional survey are different from that in the case-control survey.4. the nosoeomial Infection increases the health care costs and reduces the turnover rate of hospital beds deeply. Conscientiously make a progress on the the nosoeomial Infection control will access to both economic and social benefits.
