背景：急性哮喘的急诊（艾德）就诊是发病率的重要标志。目的：描述艾德访问急性asthene.Methods的流行病学：我们获得的数据来自全国医院门诊医疗调查，1993年至2005年，并使用哮喘的主要诊断代码（493），以确定案件。我们计算国家估计使用分配的患者就诊权重和国家率每1000美国人口与人口统计学特定的人口数据从US Census Bureau.Results：从1993年至2005年，约有23，800，000哮喘访问，占所有艾德访问的1.8%，或每1000美国人口的6.7访问的总体速率。1993年至1998年，全国就诊率有所上升（P趋势= 0.05），但1998年至2005年保持稳定（或可能下降）（P趋势= 0.07）。虽然从1998年到2005年，白色受试者的发生率下降了25%（P趋势= 0.02），但黑人受试者的发生率保持不变（P趋势= 0.80）。哮喘相关艾德总就诊率在以下人群中最高：
Background: Emergency department (ED) visits for acute asthma provide an important marker of morbidity. Objective: To describe the epidemiology of ED visits for acute asthma.Methods: We obtained data from the National Hospital Ambulatory Medical Care Survey, 1993 to 2005, and used the primary diagnosis code for asthma (493) to identify cases. We calculated national estimates by using assigned patient visit weights and national rates per 1000 US population with demographic-specific population data from the US Census Bureau.Results: From 1993 to 2005, there were approximately 23,800,000 asthma visits, representing 1.8% of all ED visits, or an overall rate of 6.7 visits per 1000 US population. The national visit rate rose between 1993 and 1998 (P-trend =.05), but was stable (or possibly decreasing) from 1998 to 2005 (P-trend =.07). Although rates for white subjects decreased by 25% from 1998 to 2005 (P-trend =.02), the rates for black subjects remained constant (P-trend =.80). The overall asthma-related ED visit rate was highest among the following groups: age
