Objective: The objective of this study is to elicit the changes in frequency of asthma hospitalization among different race groups in the United States (US).

Method: It is a retrospective data analysis. All asthma hospitalizations in the US were identified using 1994, 1999 and 2004 National Inpatient Sample (NIS) databases. NIS is the largest all-payer care database that is publicly available in the US, containing data from 5 to 8 million hospital stays from about 1000 hospitals sampled to approximate a 20-percent stratified sample of the US community hospitals. Patients admitted with diagnosis of Asthma [International Classification of Disease, 9th Revision (ICD-9) code: 493.00-493.99] were identified from NIS database and data analyzed.

Results: Asthma related hospitalization was reported less in 2004 (415,309 patients) as compared to 1994 (437,539 patients) and 1999 (444,065 patients). African-Americans had a higher proportion of admission rate, considering their population (~12%) in general population. Among race groups, asthma admission was steadily declining for Whites and African Americans, but gradually increasing in Hispanic population. Women were reported more with asthma admission than men in all racial groups. However, incidence of asthma hospitalization has increased in similar fashion over the 10 yrs in Hispanic men and women.

Conclusions: Asthma related admissions declined in White and African American populations, whereas steadily increasing in Hispanic population. Although asthma hospitalization was lower in 2004 as compared to 1994 in general, more efforts are required either in form of better health care access and awareness about the disease or by community outreach programs to diminish evolving asthma prevalence in Hispanic population in the US.
