摘要
目的探讨慢性阻塞性肺疾病急性加重(AECOPD)患者住院治疗相关危险因素,为患者住院诊疗提供依据。方法横断面观察研究山西医科大学第一医院门诊的AECOPD患者127例,按治疗情况分为住院治疗组50例,非住院治疗组77例。先对2组可能的因素进行单因素分析,然后对单因素分析中P〈0.05的因素进行多因素Logistic逐步回归分析,寻找AECOPD住院治疗的相关危险因素。结果住院治疗组与非住院治疗组单因素分析的比较中,前1年至少1次急诊住院[70.0%(35/50)比22.1%(17/77)]、化痰治疗[54.0%(27/50)比28.6%(22/77)]、家庭氧疗[42.9%(21/50)比10.4%(8/77)]、前1年急诊入院次数[(2.0±0.3)次比(0.6±0.1)次]、Pa02[(63±11)mmHg(1mmHg=0.133kPa)比(71±11)mmHg]、PaC02[(47±9)mmHg比(43±8)mmHg]、Sa02[(91±5)%比(94±3)%]、血红蛋白含量[(141±14)g/L比(149±14)g/L]、白细胞计数[(9.3±2.5)×10’/L比(8.1±2.2)×10^9/L]、BODE(B为体重指数,O为气流阻塞,D为呼吸困难,E为运动能力)指数[(4.9±2.3)比(3.0±2.1)]、6min步行试验距离[(315±118)m比(431±117)m]差异均有统计学意义(均P〈0.05);多因素Logistic回归分析结果显示前1年急诊住院次数[比值比(OR):2.485,95%置信区间(CI):2.092-4.019)],BODE指数(OR:3.303,95%CI:3.054-5.610),SaO,(OR:0.658,95%CI:0.561-0.967),均为AECOPD患者需住院治疗的独立危险因素。结论较低的血氧饱和度、较高的BODE指数和前1年多次的急诊入院可能是AECOPD患者需住院治疗的独立危险因素。
Objective To investigate the risk factors associated with hospital admission for acute exacerba- tion of obstructive pulmonary disease (AECOPD). Methods One hundred and twenty-seven outpatients with AE- COPD from the First Hospital of Shanxi Medical University were investigated through a cross-sectional and observa- tional study. They were divided into inpatient treatment group and ambulatory treatment according to treatment. First, we studied the four types of 23 possible factors with single-factor analysis ,then the factors with P value below 0.05 in single-factor analysis were proceeded to perform the multiple-factor analysis with logistic regression. We analyzed the risk factors associated with hospital admission for AECOPD. Results The single-factor analysis showed that patients with at least one visit to the hospital emergency room (ER) in the previous year[ 70% (35/50)vs 22.1% (17/77) ], mucolytic cure[54% (27/50) vs 28.6% (22/77) ,oxygen therapy[42.9% (21/50) vs 10.4% (8/77)) ,the number of visits to theER[(2.0±0.3) vs (0.6±0.1)], PaO2[(63±11)mmHgvs (72±11)mmHg],PaCO2 [(47±9)mm Hg vs (43 ±8)mm Hg],Sa02[(91±5)% vs (94±3)%],Hb[ (141±14)g/L vs (149±14)g/L] ,WBC[(9.3±2.5) xl09/Lvs (8.1±2.2) xl09/L] ,the BODE index [(4.9±2.3 ) vs (3.0±2.1 ) ] and 6MWT[ (315±118)m vs (431 ±117)m] were risk factors (P 〈0.05). According to the multiple-fac- tor analysis of with Logistic regression analysis, there were 3 factors including the number of visits to the ER (OR: 2. 485, 95%C1: 2. 092-4. 019), the BODE index( OR:3. 303, 95% (21: 3. 054-5. 610) and SaO2 ( OR:O. 658, 95 % CI: 0. 561-0. 967 ) ( P 〈 0.05 ). Conclusion Low SO2 , high BODE index score and a greater number of vis- its to the ER may be the independent risk factors of hospital admission for AECOPD patients.
