中南地区结缔组织病住院患者10年死亡趋势:2005-2014

摘要

目的:分析结缔组织病(connective tissue diseases,CTDs)住院患者在10年期间死亡原因等的变化趋势.方法:采用回顾性分析的方法,收集中南大学湘雅医院风湿免疫科在2005年1月1日至2014年12月31日期间,确诊的CTDs住院患者中所有死亡病例的所有临床资料.结果:10年期间CTDs住院患者的总体住院病死率为15.68‰.在CTDs患者的3大类死亡原因中,疾病本身占44.71%,感染占42.94%,合并症占12.35%.其中,疾病本身的死因构成比和住院病死率呈逐年下降趋势,感染和合并症的死因构成比呈逐年上升趋势.2013-2014年,感染成为最主要的死亡原因,其死因构成比为51.06%.合并肺间质病变的CTDs患者与没有合并肺间质病变的CTDs患者相比,前者的生存时间明显缩短,其死亡风险是后者的1.722倍.在各种CTDs中,特发性炎性肌病患者的总住院病死率最高(45.98‰),系统性硬化症和系统性红斑狼疮患者的因疾病本身死亡比例最高,特发性炎性肌病患者的因感染死亡比例最高,类风湿关节炎的患者因合并症死亡比例最高.结论:在CTDs住院患者中,因疾病本身导致死亡的死因构成比和住院病死率均呈逐年下降趋势;因感染和合并症导致死亡的死因构成比呈逐年上升趋势,且感染成为第一位死因.CTDs合并肺间质病变患者生存时间缩短,死亡风险增加.%Objective:To analyze the trend relevant factors leading to death and their patterns over a 10-year period in inpatients with connective tissue diseases (CTDs).Methods:All clinical data about death in inpatients with CTDs were retrospectively reviewed between 2005 and 2014 at the Department of Rheumatology and Immunology in Xiangya Hospital of Central South University.Results:In the 10-year time period,the overall hospital mortality was 15.689‰.The disease itself accounted for 44.71% of the total causes of death,infection accounted for 42.94%,and comorbidities accounted for 12.35%.The constituent ratio of deaths and the average hospital mortality caused by the disease itself declined gradually year by year,and the constituent ratio of deaths caused by infection and comorbidities increased gradually year by year (P<0.05).In 2013-2014,infection was the leading cause of death,which accounted for 51.06%.The survival time for CTDs inpatients with interstitial lung disease (ILD) was shorter than that of CTDs inpatients without ILD,and even the risk of death was 1.722 times of the latter.The proportion of deaths caused by the disease itself was the highest in systemic sclerosis and systemic lupus erythematosus,that by infection was the highest in idiopathic inflammatory myopathy (IIM),and that by comorbidities was the highest in rheumatoid arthritis.Conclusion:The proportion of deaths and the hospital mortality in CTDs inpatients caused by the disease itself show a declining trend,while the proportion of deaths caused by infection and comorbidities increase.CTDs patients with ILD have shorter survival time and an increase in risk of death.
