The aim of the present study is to report an outbreak of bloodstream infections caused by in patients undergoing postoperational procedures in the Cardiothoracic Department and to describe the epidemiological investigations and control measures undertaken. A cluster of bacteremia due to was identified in blood cultures from postoperative patients in the Cardiothoracic Surgery Department in November 2023. Active surveillance by the hospital's prevention and control team was initiated. Interviews with nurses and sanitary personnel and reviews of the most common procedures, such as hand washing, bladder catheterization, and intravenous catheter care, were performed. Culturing samples from hospital personnel, postoperative patients, and the environment, including pressure transducers, tap water, soap, therapeutic solutions, antiseptics, respirators, and various intravenous preparations, were drawn up. Overall, 225 samples were collected, including 149 blood cultures, and these were all sent to the Hospital's Microbiology Laboratory. Twenty-three out of forty-seven postoperative patients had positive blood cultures for All the postoperative patients involved in the outbreak received cefepime according to antimicrobial susceptibility testing. Three pre-prepared flushing syringes were found to be positive for as well. The Cardiothoracic Department was kept under surveillance with hand hygiene measures, infusion preparation, medical device use, and cleaning procedures reviewed by the infection's prevention and control team. Undoubtedly, nosocomial outbreaks represent an important health issue regarding morbidity, mortality, and costs. Timely interventions by the hospital's infection prevention and control team may be life-saving under these circumstances.
本研究的目的是报告心胸外科术后患者中由[具体细菌名称未给出]引起的血流感染暴发情况，并描述所采取的流行病学调查和控制措施。2023年11月，心胸外科术后患者的血培养中发现了一组由[具体细菌名称未给出]引起的菌血症。医院防控团队启动了主动监测。对护士和卫生人员进行了访谈，并审查了最常见的操作，如洗手、膀胱插管和静脉导管护理。采集了医院工作人员、术后患者以及环境样本进行培养，包括压力传感器、自来水、肥皂、治疗溶液、防腐剂、呼吸器和各种静脉制剂。总共收集了225份样本，包括149份血培养样本，所有样本均送往医院微生物实验室。47名术后患者中有23人的血培养[具体细菌名称未给出]呈阳性。所有参与暴发的术后患者均根据药敏试验接受了头孢吡肟治疗。还发现3个预先准备的冲洗注射器[具体细菌名称未给出]呈阳性。心胸外科持续接受监测，感染防控团队对手部卫生措施、输液配制、医疗设备使用和清洁程序进行审查。毫无疑问，医院感染暴发在发病率、死亡率和成本方面是一个重要的健康问题。在这种情况下，医院感染防控团队的及时干预可能会挽救生命。
