慢性肾脏疾病患者发生医院感染的特点与危险因素分析

The characteristics of nosocomial infection for patients with chronic kidney disease and analysis of risk factors

目的探讨慢性肾脏疾病患者医院感染特点及相关危险因素分析。方法回顾性分析1 132例患者的病历资料和医院感染情况。结果本组感染率为12.45%(141/1132)。感染部位以泌尿道为主,占50.35%;年龄大于60岁者、住院时间超过30 d者、有侵入性操作者、原发病中狼疮性肾炎者感染率高于其他患者(P<0.05)。年龄、住院时间、侵入性操作为慢性肾脏病患者医院感染危险因素(P<0.05)。病原体以革兰阴性细菌为主,占66.15%,其次为革兰阳性杆菌,占23.08%,霉菌占10.76%。结论慢性肾脏疾病患者医院感染与年龄、住院时间、侵入性操作等有关。积极控制危险因素,预防医院感染发生。

Objective To investigate the characteristics of nosocomial infection for patients with chronic kidney disease and analysis of related risk factors. Methods Retrospective analysis of 1132 cases of the medical records of patients and infec- tions in hospital. Results The infection rate was 12.45% （141/1132）.Urinary tract infection site accounted for 50.35%,most of infections. The rate of the nosocomial infection for the cases of age over 60years old,longer hospitalization,invasive pro cedures and lupus nephritis were higher than other cases （P 〈 0.05）. The age, hospitalization time and invasive procedures were the risk factors for the chronic kidney disease. Gram-negative bacteria accounting for 66.15%,followed by, Gram-positive bacteria accounting for 23.08%, fungi accounted for 10.76%. Conclusion Patients with chronic kidney disease infection re- late to age,invasive procedures, length of stay in hospital. Positive control risk factors,and prevent the hospital infection.
