Objective: The objective is to identify how asthma admissions are distributed among different types of hospitals in the United States (US). The study will also provide information about difference in expenditure for asthma admission based on location of hospital and how the cost of asthma admission has changed over years.
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] were identified from NIS database and data analyzed.
Results: Asthma related hospitalization was reported more in South region of the country. Urban teaching hospitals had a higher admission rate. Average cost of asthma hospitalization increased from $ 6,648 (in 1994) to $ 12,100 (in 2004). Number of days from admission to principle procedure for asthma patients has remained almost same over the years (~ 1.2 days). However, a longer duration was observed in urban non-teaching hospital as compared to urban teaching and rural hospitals. Hospital length of stay (LOS) was longer in the South region of country as compared to Northeast, Midwest and West regions. In general, average LOS for asthma admission was reduced from 4.1 days (in 1994) to 3.4 days (in 2004).
Conclusions: Asthma patients admitted to urban teaching hospitals were rewarded with shorter length of time between admission and principle procedure. More attention should be paid in prevention and treatment of asthma in regions with higher frequency of admission. The hospital admission cost for asthma patients was almost doubled between 1994 and 2004 despite a relatively constant LOS.
