- *Note: Injury counts, lifetime medical costs, and per-incident injury costs were calculated including the 349 fatal injuries reported in the NDW injury data. Fatal injuries were not included in incident injury rates to allow for comparisons with non-fatal injury surveillance data from other sources. Per-injury event costs were calculated as total cost by intent/cause divided by the total number of injury events for which costs could be assigned
- 1. The two categories of intentional injuries are self-inflicted and assault. Twelve percent of intentional injuries were self-inflicted, and 88% were from assault.
- 2.These are mutually exclusive categories. “Motor vehicle/traffic” crashes include all traffic collisions involving a motor vehicle and pedestrians, cyclists, motorcyclist, or other motor vehicles. “Other, transportation” are train, aircraft, watercraft, off-road, and other non-traffic crashes (not involving a pedestrian or cyclist). “Other, pedal cyclists” are train and non-traffic crashes involving pedal cyclists. “Other, pedestrian” are train and non-traffic crashes involving pedestrians.
- 3. Cost data were not available for office-based events or outpatient events for these injury categories. The difference between the injury event “Count” and the “Number with Non-missing Cost Data” is the number of events with missing cost data.
- 4. The “other specified” category includes “other specified and classifiable” and “other specified, not elsewhere classifiable.” Other specified injuries include those with causes not routinely reported (e.g., explosions, electric current, late effects of unintentional injury) or for which injury codes do not exist (e.g., assault by other specified means). Unspecified injuries had no cause reported, such as fractures with cause unspecified. Additional detail on missing NDW data and the impact on injury counts, rates, and costs is also provided in Additional file 1.
- 5. Unspecified injury events did not have cost data for office-based events or outpatient events. More than half of all “Unspecified” injury events were missing cost data. Because of the high cost of “Unspecified” hospital and emergency room visits (Additional file 2 Table B1), per-injury event costs for “Unspecified” injuries are very high ($14,290).
