Carbon Monoxide Poisoning ED Visits by Year, New Mexico, 2008 to 2020

Indicator Report Data View Options

Why Is This Important?

Persons visiting an ED with CO poisoning are serious poison cases. Although unintentional CO poisoning can almost always be prevented, CO is the most common cause of poisoning deaths in the United States and every year more than 20 New Mexicans die as a result of accidental or unintentional exposure to this toxic gas. Patients who survive are likely to develop long-term neurological problems. The CO poisoning ED data can be used to assess the burden of serious CO poisoning, monitor trends over time, and to inform CO exposure prevention, education, and evaluation efforts to prevent poisoning.


Emergency Department (ED) visits for carbon monoxide (CO) poisoning are the visits of New Mexico residents due to unintentional/accidental CO poisoning. These CO poisoning admissions could be fire-related, non-fire-related or of unknown cause/intent. Measures are: 1) Annual number of ED visits from CO poisoning; 2) Annual crude CO poisoning ED visit rate per 100,000 population; and 3) Annual age-adjusted CO poisoning ED Visit rate. Rates are per 100,000 population. Age-adjusted rates are calculated by the direct method to the Year 2000 US Standard population,, Age Standardization of Death Rates: Implementation of the Year 2000 Standard by Robert N. Anderson, Ph.D., and Harry M. Rosenberg, Ph.D., National Vital Statistics Reports From the CENTERS FOR DISEASE CONTROL AND PREVENTION, National Center for Health Statistics, National Vital Statistics System, Volume 47, Number 3. Data for combined years 2008-2016.

How the Measure is Calculated

  • Numerator:

    The number of ED visits due to unintentional CO poisoning by county, age, and gender within a given year.
  • Denominator:

    Number of persons living in New Mexico in a given year, by county, age and gender.

Data Issues

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.
