We examined trends in hospitalizations for asthma from 1967 to 1987 among members of a large health maintenance organization. During this time asthma discharges increased significantly among children, and especially among boys under the age of 5 years. Ninety-five percent of the increase in discharges among boys was explained by a corresponding increase in the number of boys who were hospitalized. Increased readmissions did not account for the rise. Changes in the International Classification of Diseases coding of asthma and diagnostic shift by physicians accounted for only part of the increase. A decline in hospitalizations since 1984 may reflect changes in the management of asthma in the emergency room and not a decline in severe asthma episodes.
我们调查了1967年至1987年期间一个大型健康维护组织成员中哮喘住院治疗的趋势。在此期间，儿童哮喘出院人数显著增加，尤其是5岁以下的男孩。男孩出院人数增加的95%是由于住院男孩数量相应增加所致。再入院人数增加并非导致增长的原因。哮喘的国际疾病分类编码变化和医生的诊断转变仅占增加部分的一部分。自1984年以来住院人数下降可能反映了急诊室哮喘管理的变化，而非严重哮喘发作次数的下降。
