Overview
This site provides data of the number and rate of asthma hospitalizations and emergency department (ED) visits in New York State. These data are presented by age groups, sex, month of year, and total population for 3 selected year intervals (ex. 2000-2002, 2001-2003, etc...). The table below shows key information about asthma hospitalization data.

Interpreting Data
These data show only a small proportion of people who have asthma, those whose condition is serious enough to require an 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.

About Unstable Rates
When an asthma 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 
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.
Technical Notes
- Asthma ED visit and hospitalization data for New York State was generated from the Statewide Planning and Research Cooperative System (SPARCS) database.
- An asthma ED visit or hospitalization is defined as having a principal diagnosis with an International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code of 493.
- The date of the asthma ED visit or hospitalization uses the date of hospital admission.
- Population estimates used for calculating asthma ED visits and hospitalization rates were taken from the U.S. Census Bureau. State ED visits and hospitalization rates are based on State Population Estimates File, available at Population Estimates Data Sets . New York State county level ED visits and hospitalization rates are based on County Resident Population Estimates File, available at Population Estimates Data Sets .
- Asthma ED visits and hospitalization rates and age-adjusted rates were calculated per 10,000 residents. The age-adjusted rates were calculated using the 2000 U.S. Standard Population.
