目的 分析我院重症监护病房 (ICU)患者医院感染的危险因素。方法 采用回顾性调查方法 ,对我院 ICU1997年 12月 1日～ 1999年 8月 30日间 32 6例患者的在院病历逐一调查。结果 混合型 ICU患者老年人医院感染的发生率为 15 .2 4% ,显著较其他年龄组高 ;感染部位以下呼吸道最多 31.11% ,其次为泌尿道、胃肠道和创口局部 ;基础疾病中以脑外伤患者感染例次率最高为 19.35 % ;有介入性诊疗者感染率较非介入性诊疗者高。结论 应加强对混合型 ICU高龄、脑外伤等医院感染高危疾病、使用介入性诊疗与免疫抑制剂患者医院感染的重点监控
Objective To analyze the risk factors of nosocomial infection in intensive care unit (ICU) patients in our hospital. Methods A retrospective survey was conducted to investigate the in-patient records of 32 6 patients in our hospital from December 1, 1997 to August 30, 1999. Results The prevalence of nosocomial infection in elderly patients with mixed ICU was 15.24%, which was significantly higher than that in other age groups. The respiratory tract below the infected site was up to 31.11%, followed by the urinary tract, gastrointestinal tract and wound site. Among the underlying diseases, The highest incidence of cases of traumatic brain injury was 19.35%, and those with interventional clinicians were higher than non-intervention clinics. Conclusions Key monitoring of nosocomial infections in hospitalized patients with mixed ICU, such as elderly and traumatic brain injury, should be strengthened
