![]() ![]() Table 1 demonstrates that resource use associated with stays principally for asthma differed from that of stays with a secondary diagnosis of asthma. Rates of adult asthma-related hospitalizations were lowest in the West.Among adults, mood disorders were nearly twice as likely to be the principal reason for asthma-related hospital stays than for stays with no mention of asthma.Pneumonia was the most common reason for hospitalization among adult stays noting asthma as a secondary diagnosis it accounted for 7.6 percent of these stays.Nearly three-fourths of stays principally for asthma were admitted from the emergency department.Even though only 8.2 percent of the adult population was covered by Medicaid, it was the expected payer for more than 30 percent of adult hospitalizations principally for asthma.Among adults living in poorer communities, the rate of hospital stays principally for asthma was 63.2 percent greater compared to those living in wealthier communities.While the number of adult hospital stays principally for asthma remained relatively stable between 19, the number of stays with secondary asthma more than doubled.In 2005, approximately 1.9 million adult hospital stays were related to asthma. ![]() While the number of hospital stays principally for asthma remained relatively stable between 19, the number of hospital stays noting asthma as a secondary condition more than doubled over this time period (figure 1). In 2005, there were approximately 1.9 million asthma-related hospital stays among adults asthma was listed as the principal reason for hospitalization (i.e., the principal diagnosis) for 15 percent of these stays and was listed as a secondary diagnosis for the remaining 85 percent (table 1). Because characteristics of hospital stays for asthma differ for adults and children, discussion of pediatric asthma-related stays will be presented in a separate brief (HCUP Statistical Brief #58, August 2008). This brief is the first report in a two-part series on asthma-related hospitalizations. The differing rates of asthma-related hospitalization across region and income-level are also presented. Variation in the characteristics of hospitalizations principally for asthma, stays with a secondary diagnosis of asthma, and those with no mention of asthma are examined. This Statistical Brief presents data from the Healthcare Cost and Utilization Project (HCUP) on asthma-related stays for adults at U.S. However, differences in the prevalence of asthma and disparities in outpatient treatment result in rates of hospitalizations for asthma which vary by age, gender, race, and educational background, among other factors. 2 With proper outpatient care, the disease is largely controllable and hospitalization is preventable. ![]() 1 Asthma, a chronic disease characterized by inflammation of the airways, restricts the passage of air into the lungs and leads to episodes of wheezing, coughing, chest tightness, and shortness of breath severe asthma episodes can close off airways completely and may prevent vital organs from receiving oxygen. In 2005, an estimated 22.2 million Americans had a current diagnosis of asthma with approximately 12.2 million of these individuals suffering at least one asthma attack in the previous year.
