Interpreting Data

These data show only a small proportion of people who have asthma, those whose condition is serious enough to require an emergency department (ED) visit or hospital stay.

Data show the number of asthma ED visits and hospitalizations rather than the number of patients who were admitted or seen for asthma related illness. For example, if a person was hospitalized twice they would be counted twice.

  • Asthma Age-Adjusted Hospitalization Rates

    Rates are calculated as the number of asthma hospitalizations per 10,000 residents in 5-year age groups using age-specific weights based on the estimated 2008-2010 population. The maps show average asthma age-adjusted hospitalization rates for the selected three year period. Users can compare asthma hospitalizations across counties in the following regions: New York State (whole state), New York City, New York State Excluding New York City. Users can see more clearly the differences in asthma hospitalization rates between the remaining New York State counties when New York City counties are removed from the display.

    About Unstable Rates

    When an asthma emergency department (ED) visit or hospitalization rate is based on small numbers, an increase or decrease of just 1 or 2 asthma ED visit or hospitalizations from year to year can cause the asthma ED visit or hospitalization rate to change dramatically; such a rate is likely to be unstable. Unstable asthma ED visit or hospitalization rates are marked with the symbol (unstable rate) in data tables when the rate is based on fewer than 12 cases. These rates should be interpreted with caution. For more information on rates see Help With Viewing Asthma Hospitalization and ED Visit Information.
