Health Indicator Report of Asthma Emergency Department Encounters

Asthma is one of the common chronic diseases in New Mexico, with an estimated 156,782 adults 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.


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 used to classify causes of death on death certificates and diagnoses, injury causes, and medical procedures for hospital and emergency department visits. These codes are updated every decade or so to account for advances in medical technology. The U.S. is currently using the 10th revision (ICD-10) to code causes of death. The 9th revision of clinically modified ICD(ICD-9-CM) was still in use for hospital and emergency department visits until October 1st, 2015. After this date, hospitals were required to use ICD-10-CM codes.

Data Interpretation Issues

When utilizing these data, the following caveats should be noted: Data are submitted by 36 individual hospital emergency departments. Different hospitals have different medical records systems with different capacities to extract data, file formats that are produced, and definitions for when a patient is an inpatient or an outpatient. Data submitted by individual hospital emergency departments to the interim data set are not in the National Health Level Seven (HL7) standard format or content and caution should be taken when comparing these data to other state or federal data. Data submitted have been examined for internal consistency and to determine whether they have conformed to the NMDOH request guidelines. Data do not include emergency department visits to Indian Health Services or Veteran Affair's hospitals. Data do not include emergency department visits from those New Mexico residents who visit out of state emergency departments. Emergency Department (ED) data are collected from facilities yearly. The long-term plan is for the New Mexico Department of Health (NMDOH) to collect these data through an ED electronic reporting (e-reporting) system currently being developed with the New Mexico Health Information Collaborative (NMHIC). However, not all facilities are reporting to the ED e-reporting system at this time. Therefore, in the interim, we have requested that each facility submit its data directly to the NMDOH. The department is authorized to request and receive these data under the Public Health Act which grants the department authority to "Investigate, control and abate the cause of disease" (NMSA 1978 Section 24-1-3C). Additional authority was enacted (NMAC on April 30, 2009 which specifically requires that all non-federal emergency departments in the State of New Mexico must comply with NMDOH requests for ED data.
