Study Of Nosocomial Infection And Economic Costs It Caused In A Large General Hospital

PurposeThrough investigation and study, to understand the nosocomial infection of a large general hospital infect, and analyze the related factors of nosocomial infection in order to strengthen the hospital infection prevention and control, reducing the resulting extension of the length of stay and economic loss, and provide basis for decision making of the prevention and control of nosocomial infections.MethodsThe status of hospital infection with descriptive studies, will a hospital July 1,2008-2009 on 30 June 33,774 cases of hospitalized patients were analyzed retrospectively. For the hospital infection caused by extended hospital stay and economic losses, during the period from the occurrence of nosocomial infection and nosocomial infection in patients not taking the cases and controls in the. By sections, the first diagnosis, sex, age, payment method for 1:1 match, eventually collected 269 pairs of cases in the study. EXCEL collated to establish a database later, using SPSS 13.0 software for statistical analysis of survey data,χ2 test was used to compare rates were used to compare the number of paired T test.ResultsDischarged within the period of 33,774 cases of cases,862 cases of nosocomial infection, hospital infection rate was 2.55%; 1044 cases of infection in patients with sub-second, infection rate was 3.09% case-times. ICU infection rate in the highest,41.43%; addiction medicine a minimum,0.00%; infection in the respiratory tract, blood, oral-based, accounting for 52.11%, 11.30%,10.06%; high blood pressure, heart disease, cancer, chemotherapy, radiotherapy, blood disease, diabetes, and liver cirrhosis are predisposing factors of nosocomial infection; urinary catheter, venous cannula, puncture, endotracheal intubation, drainage, endoscopy and other invasive procedures are the risk of nosocomial infection factor; hospital infection susceptible age was 60 years old and 1 years of age, infection rates were 4.00% and 3.54%; hospitalized for more than 20d infection rate up to 10.66% of patients, length of stay of patients in the infection rate of less than 7d 0.20%; pathogenic bacteria to Gram-negative bacteria, accounting for 46.72%; followed by Gram-positive bacteria, accounting for 35.86%; again for fungi, accounting for 17.42%. In the case-control study to extract the 69 pairs of preterm children, diabetic 18 pairs, pneumonia, bronchitis and 50 pairs of cerebral infarction in 18 pairs, hepatitis, liver cirrhosis 41 pairs, coronary atherosclerotic heart disease 21 pairs, fractures 13 pairs, Leukemia 39 pairs.269 cases of infection with an average hospital cost of 62,326.54 yuan, without occurrence of hospital infection control group, the average cost of 29,150.30 yuan, infection control medical costs are 2.14 times more than the average expenditure per case of infection 33,176.24 yuan, the difference is statistically significance (P= 0.000). Infected group and control group differences in average medical expenses per day (1,334.34 yuan and 1,220.41 yuan) was not statistically significant (P= 0.062), the infection group of patients is mainly due to increase in the total cost of the extension of hospital stay. Among the medical costs increased most notably medicine and treatment costs, Infection length of stay 1.85 times the control group, the average length of stay per patient extended 18.85d, the difference was significant (P= 0.000).ConclusionFirst, the incidence of nosocomial infection and patient age, underlying diseases, invasive operation, hospitalization time, irrational use of antibiotics and other factors. Second, the hospital infection will increase the economic burden of patients, extending the average length of stay of patients and reduce the turnover rate of hospital beds, as well as the efficient use of medical resources.
