Asthma Emergency Department Visits by Year, New Mexico, 2010 to 2021

Indicator Report Data View Options

Why Is This Important?

Asthma is one of the common chronic diseases in New Mexico, with an estimated 175,000 adults and 30,000 children currently having the disease. People with asthma are more likely to miss school or work, report feelings of depression, and experience an overall reduced quality of life. Asthma is also costly, with expenses from routine checkups, emergency department visits, hospitalizations, and medications putting a significant burden on families, the health care sector, and the economy. Though it cannot be cured, asthma can be controlled through quality health care, appropriate medications, and good self-management skills. When asthma is controlled, people with the disease have few, if any, symptoms, and can live normal and productive lives.


An asthma emergency department visitis a visit by a New Mexico resident to an emergency department that occurs in state with asthma listed as the primary (first-listed) diagnosis. Asthma emergency department visits include those with ICD-9-CM codes 493.0-493.49 and/or ICD-10-CM code J45.

Data Sources

  • Emergency Department (ED) dataset, Health Systems Epidemiology Program, New Mexico Department of Health
  • New Mexico Population Estimates: University of New Mexico, Geospatial and Population Studies (GPS) Program.

How the Measure is Calculated

  • Numerator:

    Number of emergency department visits where asthma is the primary (first-listed) diagnosis.
  • Denominator:

    Estimated number of New Mexico residents in a specified population over a specified time period.

Data Issues

  • Emergency Department (ED) dataset

    ICD Stands for 'International Classification of Diseases.' It is a coding system maintained by the World Health Organization and the U.S. National Center for Health Statistics and is used to classify diagnoses for hospital and emergency department visits. This coding system underwent a major revision from version 9 (ICD9) to version 10 that went into effect October 1, 2015. In most cases, the two versions do not provide comparable results and the two time periods should not be combined in a trend line. The emergency department data include visits to NON-FEDERAL HOSPITALS only. Visits to Veteran's Administration (VA) facilities and Indian Health Service (IHS) facilities have not been included, unless specifically stated otherwise. The data include all emergency department visits. An individual will be counted more than once if he or she had more than one visit over the time period. The emergency department dataset includes only New Mexico residents hospitalized in New Mexico hospitals, and may undercount injury ED visits of New Mexico residents. In cases of serious injuries near the state borders, oftentimes patients will be transported to a nearby trauma center in the bordering state.

  • New Mexico Population Estimates

    All population estimates apply to July 1 of the selected year. These estimates are considered the most accurate estimates for the state of New Mexico and should match those found on the University of New Mexico Geospatial and Population Studies website. Estimates include decimal fractions. Census tract population estimates were summed to produce County and Small Area population estimates. Population estimate totals may vary due to rounding. Population estimates for previous years are occasionally revised as new information becomes available. When publishing trend data, always be sure that your rates for earlier years match current rates on NM-IBIS that have been calculated with the most up-to-date population estimates.
