Little is known about outcomes after stepping down asthma medications within an asthma management program.
To determine outcomes of stepping down asthma medications in a pediatric asthma management program.
We performed a retrospective study of 5- to 18-year-old children with asthma in an integrated primary care practice in the United States. Data were included on participants from March 1, 2009, until December 31, 2011. We first determined whether a child was eligible for step down and next recorded whether a step-down attempt was made and if the attempt was successful. In addition to descriptive statistics for the sample demographics and the outcomes of stepping down, univariate and multivariate analyses were performed to determine predictors of successful asthma medication step-down attempts.
Of the 477 children sampled for this study, 264 (55.3%) had a guideline-eligible opportunity to step down asthma medications. An attempted step down occurred in only 89 (33.7%) of children who had guideline-eligible opportunities. A total of 166 children (34.8%) attempted a step down of asthma medication at least once (including those guideline ineligible to step down). Of children with follow-up, 96 (71.6%) of step-down attempts were successful. Time of year (any season except fall) when the step down was attempted predicted successful step down in univariate and multivariate analysis (odds ratio = 3.81; 95% confidence interval, 1.23-11.85; P = .02). Being guideline eligible for step down predicted successful step down in univariate analysis only (odds ratio = 2.51; 95% confidence interval, 1.16-5.43; P = .02).
Our findings from this sample of children participating in an asthma management program suggest that stepping down asthma medication based on National Asthma Education and Prevention Program 3 guidelines is frequently successful.
在哮喘管理项目中停止使用哮喘药物后,其结果鲜为人知。
确定在儿科哮喘管理项目中停用哮喘药物的结果。
我们在美国一家综合性初级保健诊所对 5 至 18 岁的哮喘患儿进行了一项回顾性研究。数据包括 2009 年 3 月 1 日至 2011 年 12 月 31 日期间参加者的数据。我们首先确定孩子是否符合降阶梯条件,然后记录是否尝试降阶梯以及尝试是否成功。除了样本人口统计学特征和降阶梯结果的描述性统计数据外,还进行了单变量和多变量分析,以确定成功降阶梯尝试的预测因素。
在本研究中抽样的 477 名儿童中,有 264 名(55.3%)有符合指南的机会降阶梯使用哮喘药物。在有指南规定的降阶梯机会的儿童中,只有 89 名(33.7%)进行了降阶梯尝试。共有 166 名儿童(34.8%)至少尝试过一次降阶梯使用哮喘药物(包括那些不符合降阶梯条件的儿童)。在有随访的儿童中,96 名(71.6%)降阶梯尝试成功。在单变量和多变量分析中,尝试降阶梯的时间(除秋季以外的任何季节)均预测降阶梯成功(优势比=3.81;95%置信区间,1.23-11.85;P=0.02)。在单变量分析中,符合指南规定的降阶梯条件预测降阶梯成功(优势比=2.51;95%置信区间,1.16-5.43;P=0.02)。
我们从参与哮喘管理项目的儿童样本中得出的研究结果表明,根据国家哮喘教育和预防计划 3 指南,降阶梯使用哮喘药物通常是成功的。
