**The estimate has been suppressed because 1) The relative standard error is greater than 30% or when the relative standard error can't be determined. Consider aggregating years to decrease the relative standard error and improve the reliability of the estimate. 2) the observed number of events is very small and not appropriate for publication, or 3) it could be used to calculate the number in a cell that has been suppressed.

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.[[br]][[br]] * A dash (-) means that the relative standard error (RSE) is below 0.30 and the count or rate may be considered stable. [[br]] Problems with statistical instability typically occur when there is a small number of health events in a small population. For more information on statistical stability, visit the MT-IBIS Reliability & Validity page []. [[br]][[br]]


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.[[br]][[br]]

Death Certificate Data

Death certificates in Montana are filed by the person in charge of disposition (funeral directors, coroners or family members). Filers obtain demographic information from an informant, usually a family member of the decedent. The cause of death is certified by one of several authorized practitioners (physician, physician assistant, advanced practice registered nurse, or coroner). Accidental and suspicious deaths are referred to the coroner in the county of death. Most death certificates are entered and filed in the electronic Vital Statistics Information Management System. VSIMS includes extensive edits for completeness and consistency. In addition, submitted records are reviewed by the Montana Office of Vital Statistics. The data are transmitted to the National Center for Health Statistics (NCHS) where they are machine coded into ICD-10 cause-of-death codes. NCHS returns the coded files to the OVS. The mortality data in this IBIS-Q query module have been derived from death certificates in participation with the National Vital Statistics System, and are maintained and provided by the Office of Vital Statistics, Montana Department of Public Health and Human Services. The causes of death were coded using the 10th Revision of the International Classification of Diseases (ICD-10) codes.[[br]][[br]]
