摘　　要：目的探讨脑卒中手术患者医院感染与静脉血栓之间的相关性,为临床医务人员采取针对性预防与控制措施提供科学依据。方法前瞻性收集某医院2016年1月—2018年12月所有脑卒中手术患者的临床资料,根据是否发生医院感染分为感染组和非感染组,将两组患者进行1∶1倾向评分匹配(PSM),分析脑卒中患者术后医院感染与静脉血栓之间的关系。结果共纳入816例脑卒中手术患者,发生医院感染213例,医院感染发生率为26.10%,通过PSM均衡混杂因素后,发现患者医院感染与静脉血栓之间具有相关性(P<0.001),Pearson列联系数C为0.192。不同部位医院感染组间静脉血栓发生率比较,差异具有统计学意义(P=0.037)。结论通过PSM法均衡混杂因素后,脑卒中手术患者医院感染与静脉血栓之间存在正相关性,在患者不良预后上可能具有协同作用,因此,应加强患者术后监测,做到早发现、早诊断、早治疗,及早采取干预措施,以降低并发症的发生风险,改善患者预后。Objective To explore the correlation between healthcare-associated infection(HAI)and venous thrombosis in stroke patients undergoing surgery,and provide scientific basis for health care workers to take targeted prevention and control measures.Methods Clinical data of all stroke patients in a hospital from January 2016 to December 2018 were prospectively collected,they were divided into infection group and non-infection group accor-ding to whether HAI occurred,two groups of patients were matched with 1∶1 propensity score matching(PSM),relationship between post-operative HAI and venous thrombosis in stroke patients was analyzed.Results A total of 816 stroke patients were included in study,213 cases(26.10%)of HAI occurred,after confounding factors were balanced by PSM,there was a correlation between HAI and venous thrombosis(P<0.001),Pearson contingency coefficient C was 0.192.Incidence of venous thrombosis was different among different HAI sites(P=0.037).Conclusion After the confounding factors are balanced by PSM,there is a positive correlation between HAI and thrombosis in stroke patients undergoing surgery,and may have a synergistic effect on the adverse prognosis of patients,therefore,post-operative monitoring should be strengthened,early detection,early diagnosis,early treatment and early intervention measures should be taken to reduce the risk of complication occurrence and improve the prognosis of patients.
