A Comparison Between 1998 and 1999Tennessee Crash Outcome Data Evaluation System
Injuries resulting from motor vehicle crashes remain a major public healthproblem. These injuries cause unnecessary burden of increased taxes andinsurance premiums. They can be prevented, or reduced, but only if weunderstand what the severity of these crashes is, and their associated healthcare costs. Crash data alone do not indicate the injury problem in terms ofthe medical and financial consequences. By linking crash, vehicle, andbehavior characteristics to their specific medical and financialoutcomes, we can identify prevention factors.
-National Highway Traffic Safety Administration
The Crash Outcome Data Evaluation System (CODES)evolved from a congressional mandate to report on thebenefits of safety belts and motorcycle helmets. NHTSAhas funded Alaska, Arizona, Connecticut, Delaware,Georgia, Hawaii, Iowa, Kentucky, Maine, Maryland,Massachusetts, Minnesota, Missouri, Nebraska, Nevada,New Hampshire, New Mexico, New York, North Dakota,Oklahoma, Pennsylvania, Rhode Island, South Carolina,South Dakota, Tennessee, Utah and Wisconsin to linkstatewide crash and injury data. Tennessee has been anactive participant in this project since 2001.
At the current time, the CODES project is able to linkcrash data from the Department of Safety, and medical data fromemergency rooms, hospitals, and trauma from the Department ofHealth, as well as information from the Department ofTransportation. The type of injuries, their severity, and the costincurred by persons injured in motor vehicle crashes aredescribed and computerized and this statewide data are linkedwith other related data and evaluated. This linked data identifiesthe types of injuries and the costs that result from specific driver,vehicle, and crash characteristics.
Vehicle crash data in this newsletter reflects the comparison ofdriver safety belt usage and hospital costs for 1998 and 1999.The police officer indicates on the crash report whether thedrivers were wearing safety belts or not at the crash site.
In Tennessee, safety belt usage was 84 percent among femaledrivers in crashes both in 1998 and 1999. In contrast, only 71
percent of all male drivers involved in crashes used safety beltsboth years. This is a significant difference in usage. Betweenmales and females, there was no improvement of usage in eithersex. Out of 15,739 female drivers in 1998, 2,490 did not wearsafety belts. In 1999, of 14,723 female drivers aged 15 and up,
2,298 did not wear safety belts. Out of 13,094 male drivers in1998, 3,820 did not wear safety belts. In 1999, 3,702 of12,855 male drivers aged 15 and up did not wear safetybelts.

The following graphs show thedistribution and hospital costs of young, middle aged, andelderly drivers. For this newsletter, the young drivers areclassified as 15-19 years of age, the middle aged are 20-74,and the elderly are aged 75 and above. Hospital costsassociated with young drivers are not as high, in large part,because they heal faster and have fewer complications.Elderly drivers, on the other hand, have higher hospital costsbecause they do not heal as fast and more complications arelikely to be involved. Of those wearing safety belts, in 1998,elderly female drivers cost an average of 280 percent morethan young female drivers, and in 1999, the average rose tobe 406 percent higher than for young female drivers. Elderlymale drivers cost an average of 179 percent more in 1998,and 129 percent more in 1999 than young male drivers.Without safety belts, elderly female drivers in 1998 cost anaverage of 147 percent more and in 1999, 151 percent more.For 1998, elderly male drivers cost an average of 242 percentmore than young male drivers and in 1999, the increase was125 percent over young male drivers.
Total hospital costs increased 12 percent for 1999 over1998 ($66,677,834 and $59,602,365, respectively) andaverage costs increased by 17 percent ($2,418 and$2,067, respectively). This is an interesting phenomenonsince the number of total accidents decreased. However,the number of drivers increased, indicating that there weremore multi-vehicle accidents. The general inflation rate for
1999 was 2.2 percent. The increase, however, in medicalcare and medical care services was 3.5 percent and 3.4percent, respectively. Medical costs rose more than thegeneral inflation rate by 59 percent. Keep in mind that theincreases in hospital costs per person in 1999 will bepartly due to this increase in hospital costs.

Black female drivers were the groupmost likely to wear safety belts. Safetybelt usage by black female driversdecreased in 1999 by 3 percent fromthe previous year. Even so, as the graphshows, black drivers wear safety beltsmore than white drivers, and blackmales in particular wear safety belts 10percent more than white males. Thepercentage of males reported with nosafety belt usage was 29 percentcompared to 16 percent of females.

In 1998, men accounted for 58 cents ofevery dollar spent on hospital chargesresulting from crashes, and womenaccounted for 42 cents of every dollarcompared to 59 cents and 41 cents in1999.
The total crash related hospital costs in1998 for all female drivers $24,886,090.For all male drivers, the total hospital costs $34,716,275. In1999, the total hospital costs for all female drivers$27,202,768. For all male drivers, the total hospital costs$39,475,066. In female drivers involved in crashes, 1999 sawan increase of 9 percent in total hospital costs ($27,202,768)and an increase of 17 percent in average hospital costs($1,848). In male drivers involved in crashes, 1999 saw anincrease of 14 percent in total hospital costs ($39,475,066)and an increase of 16 percent in average hospital costs($3,071).
In 1998, the averagehospital costs permale driver ($1,767when wearing safetybelts and $4,799when not wearingsafety belts) werehigher than averagehospital costs perfemale driver ($1,276when wearing safety belts and $3,205 when not wearingsafety belts). In 1999, the average hospital costs per maledriver ($2,016 when wearing safety belts and $5,680 whennot wearing safety belts) were higher than average hospitalcosts per female driver ($1,551 when wearing safety beltsand $3,450 when not wearing safety belts). It may beconcluded that male drivers were more severely injured thanfemale drivers. In 1999, the additional hospital costs incurreddue to male drivers not wearing safety belts exceeded thecosts from the previous year by $1.8 million. This cost aloneincreased by 15 percent. From year to year, several factors inaddition to safety belt usage may contribute to the variation incosts. Some factors could include the number of crashes,number of drivers, and the rise in hospital costs and inflationin that year. For both sexes, the two year total potentialsavings combined would have been more than $35 million.

More than $17 million in
hospital charges could have
been saved in 1998 and $18
million in 1999 if all drivers
had worn safety belts.
For ages 15-64, the average
male driver in 1998 and 1999
suffered more severe injuries
when not wearing a safety belt
than the average female driver.
On average, hospital costs
per driver increase an
incredible 157% when driver
is wearing no safety belt.

Unbelted drivers only have a 12 percent chanceof escaping without pain, injury, or death. On theother hand, belted drivers have about a 30percent chance. About 94 percent of all belteddrivers will walk away with nothing worse thanbruises. Only 80 percent of unbelted crash driverscan claim that.
The chances of dying in a crash increase whennot wearing safety belts. In 1998, an unbelteddriver was 4.4 times more likely to die from anangle collision, 4.4 times more likely to die from ahead-on collision, 12 times more likely to die froma sideswipe collision, and 17 times more likely todie from a rear-end collision. In 1999, an unbelteddriver was 7.2 times more likely to die from anangle collision, 7.9 times more likely from a head-on collision, 2.8 times more likely from asideswipe collision,and 33.9 timesmore likely from arear-end collision. In1998, 6 out of 10drivers killed incrashes were notwearing safety belts.In 1999, it was 7out of 10. No matterwhat type ofcollision, drivers arealways more likely tosurvive if wearing asafety belt.
