Oregon Injury and Violence Prevention

Technical Notes

The Oregon Violent Death Reporting System (ORVDRS) is a statewide system that collects detailed information on all homicides, suicides, deaths of undetermined intent, deaths resulting from legal intervention, and deaths related to unintentional firearm injuries. ORVDRS collects data from Oregon medical examiners’ reports, local police reports, death certificates and the Homicide Incident Tracking System.

The manner of death showed from data dashboard was determined according to International Classification of Diseases, Tenth Revision (ICD-10) codes for the underlying cause of deaths on death certificates. If the ICD-10 code is not available, the manner of death is determined according to death certificate and/or medical examiner report. Occasionally, data sources may record conflicting determinations on the manner of death.

Deaths relating to the Death with Dignity Act (physician-assisted death in terminally ill patients) are not classified as suicides by Oregon law and therefore are excluded from data collection and the data dashboard.

Death rate is calculated by dividing the number of deaths in a population in a period by resident population. Some rates are based on a small number of deaths so from year to year, large swings can occur in rates. The rates based on small numbers (less than 20 events) may be unstable due to random chance factors, and should be used with caution. Rates based on counts less than 5 are suppressed due to confidentiality.

The following are definitions of terms identified in the data dashboard. The details could be found from NVDRS coding manual.
