Indicator Report - Asthma Hospitalizations

Why Is This Important?

Asthma can usually be managed in an outpatient setting, reducing the need for inpatient hospitalization. Tracking rates of hospitalization can aid in identifying populations or areas with inadequate access to routine medical care.

An asthma attack can result in a hospitalization and can be initiated by a variety of triggers. Some of these include exposures to environmental tobacco smoke, dust mites, cockroach allergen, mold, pets, strenuous physical exercise, and air pollution. Two key air pollutants that can affect asthma are ozone (found in smog) and PM or particulate matter (found in haze, smoke, and dust).

The majority of problems associated with asthma, including hospitalization, are preventable if asthma is managed according to established guidelines. Effective management includes control of exposure to factors that trigger exacerbations, adequate pharmacological management, continual monitoring of the disease, and patient education in asthma care.

Map of Age-adjusted Asthma Hospitalizations per 10,000 Population by Utah Small Area, 2010-2012

supplemental image
This map was made using a method called "fixed effect test of significance" where classes are based on statistically higher or lower rates than the state rate. Please note that the years aggregated to create the map are different than the years aggregated in the data table. This difference is unlikely to yield different results.

Data Notes

The ICD-9 code used to define asthma is 493.   The rates were age-adjusted to the U.S. 2000 standard population.

Due to Utah Small Area boundary changes in 2009 and 2012, some of the Small Area rates presented include only select years of data. See chart for details.

Data Sources

Utah Inpatient Hospital Discharge Data, Office of Health Care Statistics, Utah Department of Health. Population estimates produced by staff in the UDOH Center for Health Data and Informatics. Linear interpolation of U.S. Census Bureau and ESRI ZIP Code data provided annual population estimates for ZIP Code areas by sex and age groups, IBIS Version 2013.
