摘要 调查细菌L型医院感染的危险因素共22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。

    Abstract To survey the risk factors of nosocomial bacterialL-form infections, 22 risk factors were investigated and analysed with nonconditionallogistic regression.Resutts showed through single factor regression that cancer,chronicdisease,primary infection, longer than 3-week hospitalization before the onset ofnosocomial infection,preventive use of antibiotics longer than 7 days, preventive use ofcell wall depressive antibiotics, steroid use, anti-tumor drugs and urine guide techniquewere significant factors. Multiple factor regression demonstrated that two modelsincluding cell wall depressive antibiotics, primary infection, urine guide technique cellwall depressive antibiotics, primary infection, anti-tumor drugs and longer than 3-weekhospitalization before the development of nosocomial infection were conjugated properly.It suggested that the surveillance of risk factors of nosocomial bacterial L-forminfections was helpful to control nosocomial infections.
