细菌L型医院感染危险因素的调查

调查细菌L型医院感染的危险因素共 2 2项 ,应用非条件logistic回归分析处理。结果 :单因素分析显示癌症、慢性病、原发感染灶、医院感染前住院≥ 3周、抗菌药预防应用≥ 7天、抑制细胞壁的抗菌药预防、肾上腺皮质激素、抗癌药和导尿具有显著性。多因素分析表明抑制细胞壁的抗菌药、原发感染灶和导尿以及抑制细胞壁的抗菌药、原发感染灶、抗癌药和医院感染前住院≥ 3周两个模型配合适度较好。说明监测细菌L型医院感染的危险因素 ,有利于医院感染的控制。

Retrospective Study on the Risk Factors in Patients with Nosocomial Bacterial L-Form Infection

To survey the risk factors of nosocomial bacterial L-form infections, 22 risk factors were investigated and analysed with nonconditional logistic regression.Resutts showed through single factor regression that cancer,chronic disease,primary infection, longer than 3-week hospitalization before the onset of nosocomial infection,preventive use of antibiotics longer than 7 days, preventive use of cell wall depressive antibiotics, steroid use, anti-tumor drugs and urine guide technique were significant factors. Multiple factor regression demonstrated that two models including cell wall depressive antibiotics, primary infection, urine guide technique cell wall depressive antibiotics, primary infection, anti-tumor drugs and longer than 3-week hospitalization before the development of nosocomial infection were conjugated properly. It suggested that the surveillance of risk factors of nosocomial bacterial L-form infections was helpful to control nosocomial infections.
