2024年新疆维吾尔自治区187所医疗机构器械相关感染目标性监测报告

Report of targeted surveillance of device-associated infections in 187 medical institutions in Xinjiang Uygur Autonomous Region in 2024

  • 摘要: 目的 分析新疆维吾尔自治区187所医院重症监护病房(ICU)器械相关感染的流行病学特征及病原菌分布情况,为全疆医院ICU器械相关感染管理提供科学依据。方法 采用新疆院感监测平台收集2024年全疆医院ICU住院患者资料,对器械相关感染情况进行汇总分析。 结果 2024年全疆医院ICU住院患者呼吸机相关肺炎(VAP)发病率为1.46‰,二级医院、床位数>1 000~1 500张的医院发病率分别为2.63‰、3.46‰;中央导管相关血流感染(CLABSI)发病率为0.20‰,二级医院、床位数>1 000~1 500张的医院发病率分别为0.23‰、0.45‰;导尿管相关尿路感染(CAUTI)发病率为0.47‰,二级医院、床位数>1 000~1 500张的医院发病率分别为0.48‰、0.94‰;本次共检出1 553株病原菌,其中革兰阴性菌978株(62.97%),革兰阳性菌480株(30.91%),真菌95株(6.12%)。结论 全疆医院ICU 器械相关感染中VAP发病率最高;CLABSI虽然发病率较低,但感染后果严重仍需重点关注。器械相关感染病原菌主要以革兰阴性菌为主。合理的器械相关感染监测与防控措施可以有效减少感染发生,各级医院都需要加强导管相关器械和抗菌药物的规范化使用,开展多部门协同防控举措,控制器械相关感染。

     

    Abstract: OBJECTIVE To analyze the epidemiological characteristics and distribution of pathogens of device-associated infections in intensive care units (ICUs) of 187 hospitals in Xinjiang Uygur Autonomous Region, and to provide scientific evidence for the management of device-associated infections in ICUs across the region. METHODS The Xinjiang Hospital Infection Surveillance Platform was utilized to collect data on ICU inpatients across Xinjiang in 2024, and the device-associated infections were summarized and analyzed. RESULTS The incidence of ventilator-associated pneumonia (VAP) was 1.46‰ among the hospitalized patients of ICUs in Xinjiang in 2024; the incidence was 2.63‰ in the secondary hospitals, 3.46‰ in the hospitals with 1 000 to 1 500 beds. The incidence of central line-associated bloodstream infections (CLABSI) was 0.20‰; the incidence was 0.23‰ in the secondary hospitals, 0.45‰ in the hospitals with 1 000 to 1 500 beds. The incidence of catheter-associated urinary tract infections (CAUTI) was 0.47‰; the incidence was 0.48‰ in the secondary hospitals, 0.94‰ in the hospitals with 1 000 to 1 500 beds. A total of 1 553 pathogens were detected, including 978 gram-negative bacteria (62.97%), 480 gram-positive bacteria (30.91%) and 95 fungi (6.12%). CONCLUSIONS In the device-associated infections in the ICUs across Xinjiang, the incidence rate of VAP is the highest. Although the incidence rate of CLABSI is relatively low, the consequences of infection are severe and still require significant attention. The main pathogens responsible for device-associated infections are predominantly gram-negative bacteria. Reasonable monitoring and prevention measures for device-associated infections can effectively reduce the occurrence of infections. Hospitals at all levels need to strengthen the standardized use of catheter-related devices and antimicrobial agents, and implement cross-departmental prevention and control measures to control device-related infections.
