哮喘用药指南对哮喘控制用药和哮喘发作率的影响:比较1997~1998与2004~2005的数据
2012/01/31
摘要
背景:有关人群中哮喘控制治疗用药与哮喘发作率的关系尚不清楚。
目的:通过计算哮喘控制用药和总哮喘用药比例,评价1997~1998年和2004~2005年2阶段内哮喘控制治疗用药的变化,及用药变化与哮喘发作率变化之间的关系。
方法:本试验为以人群为基础的横断面研究,受试者来自于1997~1998年和2004~2005年。受试者为来自于医疗费用小组调查(MEPS)中年龄为5~56岁的哮喘患者。主要研究指标为比较两个阶段哮喘控制用药与总哮喘用药比大于0.5的患者和哮喘发作率(因哮喘全身糖皮质激素或急诊就诊/住院)。
结果:经人口统计学因素校正后,与1997~1998年相比,2004~2005年哮喘控制用药与总哮喘用药比值大于0.5的患者比率改善了16.1% (95% CI: 10.8%, 21.3%)。在任何组,1997~1998年和2004~2005年,每年哮喘发作率无显著变化(0.27/年至0.23/年)。与白人相比,1997~1998年和2004~2005年,非洲裔美国人和西班牙裔美国人具有较高的哮喘发作率,哮喘控制用药与总哮喘用药比值大于0.5的患者比率也较低,但差异无显著性。
结论:美国人群中,1997~1998年与2004~2005年间,哮喘控制用药与总哮喘用药比值增加与哮喘发作下降无关。

Abstract
BACKGROUND: The relationship between asthma controller medication use and exacerbation rates over time is unclear at the population level.
OBJECTIVE: To estimate the change in asthma controller medication use between 2 time periods as measured by the controller-to-total asthma medication ratio and its association with changes in asthma exacerbation rates between 1997-1998 and 2004-2005.
METHODS: The study design was a cross-sectional population-level comparison between individuals from 1997-1998 and 2004-2005. Study participants were individuals aged 5 to 56 years identified as having asthma in the Medical Expenditure Panel Survey (MEPS). The main outcome measures were a controller-to-total asthma medication ratio greater than 0.5 and asthma exacerbation rates (dispensing of systemic corticosteroid or emergency department visit/hospitalization for asthma) in 1997-1998 compared with 2004-2005.
RESULTS: The proportion of individuals with a controller-to-total asthma medication ratio greater than 0.5, when adjusted for other demographic factors, has improved by 16.1% (95% CI: 10.8%, 21.3%) for all individuals from 1997-1998 to 2004-2005. Annual asthma exacerbation rates did not change significantly in any group from 1997-1998 to 2004-2005 (0.27/year to 0.23/year). African American and Hispanic individuals with asthma had higher asthma exacerbation rates and a lower proportion with a controller-to-total asthma medication ratio greater than 0.5 than whites in both 1997-1998 and 2004-2005; however, these differences were not statistically significant.
CONCLUSIONS: An increase in asthma controller-to-total medication ratio in a sample reflective of the US population was not associated with a decreased asthma exacerbation rate comparing 1997-1998 and 2004-2005.
