Query Results for Infant Mortality for Environmental Public Health Tracking (EPHT) Program - Infant Mortality Rates, Deaths Per 1,000 Live Births

Year Filter: 2012-2016
Data Grouped By:NM Small Areas

**The count or rate in certain cells of the table has been suppressed either because 1) the observed number of events is very small and not appropriate for publication, or 2) it could be used to calculate the number in a cell that has been suppressed. For survey queries, percentages calculated from fewer than 50 survey responses are suppressed.

Infant Mortality

Infant mortality is defined as the death of an infant under one year of age. Neonatal mortality is the death of an infant age 0 to 27 days, and postneonatal mortality, an infant age 28 to 364 days. The Infant Mortality Rate is most often calculated as infant deaths in a given year per 1,000 live births in the same year (death period method). This NM-IBIS query module uses the "death period" method. Infant mortality may also be calculated as deaths of infants born in a given year per 1,000 infants born in that year. That method of calculating infant mortality is called the birth cohort method.

New Mexico Resident Infant Deaths

The NM-IBIS Infant Mortality query module includes only deaths of infants who were residents of New Mexico. Infants who were non-residents, and deaths for which state residency was unknown have been excluded.

ICD Codes

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.

For information on specific ICD codes used for causes of infant death, please visit [].

Statistical Stability

Statistical stability, reported in the data table, is based on a statistic called the "Relative Standard Error," or RSE, which is the standard error expressed as a proportion of the point estimate (e.g., 30% of the point estimate). The following conventions are used here to interpret the RSE. * A dash (-) means that the relative standard error (RSE) is below 0.30 and the count or rate may be considered stable. * "Unstable" is displayed when the RSE is 0.30-0.50. An unstable count or rate may fluctuate widely across time periods due to random variation (chance). * "Very Unstable" is displayed when the RSE is greater than 0.50. A very unstable count or rate should not be used to inform decisions. You may combine years or otherwise increase the population size used in the query to achieve a more stable count or rate. Problems with statistical instability typically occur when there is a small number of health events in a small population.

Death Certificate Data

Death certificates in New Mexico are required to be filed by funeral directors. Funeral directors obtain demographic information from an informant, a close family member of the decedent. The cause of death is certified by the decedent's physician or the physician that attended the death. Accidental and suspicious deaths are certified by the Office of the Medical Investigator. Death certificate data go through extensive edits for completeness and consistency. The DOH Bureau of Vital Records and Health Statistics (BVRHS) does annual trainings for funeral directors and local registrars.

When death certificates are received the cause of death literals are keyed into software locally by the BVRHS, then shipped to the National Center for Health Statistics (NCHS) where they are machine coded into ICD-10 cause-of-death codes. NCHS returns the ICD-10 codes to BVRHS where the death records are updated.

*SUID versus SIDS

Many infant deaths previously ruled SIDS by pathologists or coroners are now usually coded as one of three Sudden Unexpected Infant Death (SUID) causes of death: ICD-10=R95 (SIDS), ICD-10=W75 (Accidental Suffocation or Strangulation in Bed) and ICD-10=R99 (Unknown or ill-defined) cause. Here's a link to a Sudden Unexpected Infant Death (SUID) factsheet that is useful: [].

Confidence Intervals for Zero Values

For rates where the count is zero, a numerator of "3" was used to calculate the confidence interval (per Lilienfeld and Stolley, __Foundations of Epidemiology__, 1994, p. 303).
