【摘要】：目的探讨建立住院患者医院感染风险评估机制,分类落实预防控制医院感染措施,降低医院感染率。方法选取医院2010年5月-2013年5月发生医院感染793例为试验组,随机抽取未发生医院感染的1 000例为对照组,分别对两组患者的年龄、病情、住院天数、侵入性操作、抗菌药物使用等危险因素进行统计分析,构建logistic回归模型,估计参数,标准化各影响因素系数,计算出分值及风险级别。结果根据统计变量结果并结合医院感染管理日常监测指标,遴选出疾病诊断、基础疾病、导管植入、呼吸机使用、手术类型及时间、麻醉类型、有无植入物、放化疗、糖皮质激素使用、抗菌药物使用、住院时间等13个影响因素作为评估指标;通过构建logistic回归模型,评价模型效果:灵敏度83.6%,特异度76.2%;计算出各评估指标分值,≥5分为高危人群;建立医院感染风险评估表。结论建立住院患者医院感染风险评估表,通过对住院患者的有效评估,分类预防控制医院感染,对高危患者提前干预预防控制,可预期达到降低医院感染率。
[Abstract]:Objective to establish a risk assessment mechanism for nosocomial infection of inpatients and to carry out the measures to prevent and control nosocomial infection and reduce the nosocomial infection rate. Methods A total of 793 patients with nosocomial infection from May 2010 to May 2013 were selected as experimental group, and 1 000 cases of nosocomial infection were randomly selected as control group. The risk factors such as antimicrobial use were statistically analyzed, logistic regression model was constructed, parameters were estimated, factors were standardized, scores and risk levels were calculated. Results according to the results of statistical variables and combined with the daily monitoring index of hospital infection management, the diagnosis of diseases, basic diseases, catheter implantation, ventilator use, operation type and time, anesthesia type, whether there were implants, radiotherapy and chemotherapy were selected. Thirteen factors, such as glucocorticoid use, antimicrobial use, hospitalization time, were used as evaluation indexes. By constructing logistic regression model, the effectiveness of the model was evaluated as follows: sensitivity 83.6, specificity 76.2g, score of each evaluation index calculated. 鈮，
