   摘要
   目的：哮喘是导致急诊就诊的原因之一。关于消费者广告指示(DTCA)对健康护理的影响一直存有诸多争论。本研究旨在评估DTCA花费与哮喘相关急诊的相关性。
   研究设计：本研究结合了医疗补助管理数据和国家哮喘药物的广告数据。样本量由180584例年龄为5-18岁确诊为哮喘的医疗补助儿童组成。其中20%的儿童曾有哮喘相关急诊科就诊。
   结果：本研究发现DTCA花费与哮喘相关急诊科就诊量的下降相关(OR = 0.75; CI: 0.64, 0.89)。然而，在达到更高水平的DTCA花费时，将增加哮喘相关急诊科就诊的概率(OR = 1.25; CI: 1.05, 1.49)，提示DTCA与哮喘相关急诊科就诊的相关性降低。
   结论：本研究结果表明DTCA可改善医疗补助的哮喘儿童健康结果。

ABSTRACT
OBJECTIVE: Asthma is a leading cause of emergency department visits. There has been much debate on the impact of direct to consumer advertising (DTCA) on healthcare. This study seeks to examine the association between DTCA expenditure and asthma-related emergency department use.
STUDY DESIGN: In this study we combined Medicaid administrative data and a national advertising data on asthma medications. The sample size consisted of 180,584 Medicaid-enrolled children between the ages of 5 and 18 who had an asthma diagnosis. Twenty percent of the Medicaid-enrolled children in the sample had asthma-related emergency department visits.
RESULTS:We found that DTCA expenditure is associated with a decrease in asthma-related emergency department visits (OR = 0.75; CI: 0.64, 0.89). However, at higher levels of DTCA expenditure the likelihood of asthma-related emergency department visits increases (OR = 1.25; CI: 1.05, 1.49), indicating a decreased relationship between DTCA and asthma-related emergency department visits.
CONCLUSIONS: Our findings suggest that DTCA may be associated with improved health outcomes for Medicaid-enrolled children with asthma.
