Any differences in totals result from rounding of national projections to the lowest whole number
(a) – Number of incidents found was below 20, which limits the reliability of the national projection
1 – Treated and released, or examined and released without treatment
2 - Treated and transferred to another hospital
4 – Treated and admitted for hospitalization (within same facility)
8 – Fatality including DOA

National Hospital Ambulatory Medical Care Survey – Data From Emergency Departments
    The 2000 NHAMCS file for emergency department visits contains 25,622 records, 8,791 of which are for unintentional injuries. The text fields of the unintentional injury records were searched for certain words that would likely be used in describing one of the types of non-traffic motor vehicle-related incidents under study.
A total of five incidents involving a vehicle backing up were found in the NHAMCS emergency department file. Details of those incidents are provided below.

*When there are 30 or more similar incidents, the patient weights for all of the incidents can be added to together to create a projection of the national total of such incidents. The patient weights presented here are for information purposes only. They are of little or no predictive value since they each represent only one incident. Even if the incidents are considered to be similar, there are still only five such incidents here so no reliable predictions as to the national total of such incidents can be made.
