Asthma Emergency Department Visits Data
Asthma emergency department visits include the number of patients seen in an emergency department for asthma. These data can be used to identify trends and patterns of emergency department visits over time and in different geographic areas. This data may be compared with other risk factors, such as air pollution, to identify at-risk populations and environmental relationships. Advanced options include age group, and gender.
Asthma Emergency Department Visits Data Visualization
The ED Visit Count is the number of emergency department visits with a primary diagnosis code for asthma.
The Crude Rate (Per 10K) is the rate of emergency department visits with a primary diagnosis code for asthma per 10,000 Population.
The Age Adjusted Rate (Per 10K) is the age adjusted rate of emergency department visits with a primary diagnosis code for asthma per 10,000 Population. Age adjustment to the 2000 Standard US Census is done to allow direct comparison of rates in counties and state with different population age distributions.
The Average Daily ED Visits is the number of ED visits with a primary diagnosis of asthma in a given month divided by the number of days in the month.
The numbers and rates of asthma emergency department visits in Iowa by year, age group, and gender.
If an asthma measure is going up or down over time.
If a segment of a population is at higher risk for hospitalization or a visit to the emergency department due to asthma.
To inform the public about asthma emergency department visits.
For program planning and evaluation by state and local partners.
What causes asthma, or what leads to asthma emergency department visits.
The total burden of asthma in a population.
The number of people who visited the emergency department due to asthma. Because personal identifiers are removed from the hospital discharge data before analysis, individuals who have multiple hospitalizations or emergency department visits cannot be identified.
Hospitalization and emergency department data are collected by the Iowa Hospital Association on behalf of HHS in accordance with Iowa Code section 135.166.
Bridged-race population estimates from the National Center for Health Statistics and US Census. Data from 2000 to 2009 are based on intercensal population estimates and 2010-most current year are based on the postcensal population estimates.
The Iowa Public Health Tracking portal displays Emergency Department visit data from the year 2003 through the most recent year of data available.
Emergency Department visits are defined as Iowa residents who are treated and released or subsequently admitted to a facility in Iowa.
Asthma emergency department visits have asthma as the first-listed diagnosis.
Asthma is defined as the International Classification of Disease 9th Revision, Clinical Modification (ICD-9-CM) codes that begin with 493.
Asthma is defined as the International Classification of Disease 10th Revision, Clinical Modification (ICD-10-CM) codes that begin with J44 or J45.
Multiple emergency department visits by the same patient cannot be identified, and are not excluded.
These data are not appropriate for estimating the total burden of asthma.
Iowa residents discharged from hospitals in surrounding states are not included, so emergency department visit rates for counties in which residents are likely to receive care in a surrounding state may be underestimated. Rates for counties in which residents are likely to visit hospitals that do not submit data to the Iowa Hospital Association (e.g., Veteran's Administration, Indian Health Services hospitals, and institutionalized populations) may also be artificially low.
