2
Creation of TBI Data Set File Linkages Trauma Registries UB92 Death Certificates TBI Data Set Link and Remove Duplicates Filter TBI’s
3
Creation of TBI Data Set Results for 1997-1999 n 1997: 3,224 cases identified n 1998: 2,457 cases identified n 1999: linkage in progress
4
Crash-TBI Linkage 3,244 TBI’s 225,000 drivers 616 TBI cases linked to crash-involved drivers
5
Case-Control Analysis Outcome: TBI/No TBI n 616 linked Crash- TBI records n Dropped non-injury crashes from the unlinked Crash records n Randomly selected 1,232 records from the remaining Cases Controls Independent Variables n Age n Gender n Seat belt use n Urban/rural location n Type 1st harmful event n Vehicle type n Driving under the influence n Posted speed limit n Roadway condition n Weather n Impact point n Highway type
6
Selected Results Seat Belt Use n Crash-involved drivers who were reported not wearing belts had 6.6 times greater risk of TBI n Males ages 15-29 were 35% of all unbelted TBI’s but only 21% of the population of Kentucky in 1997.
7
Selected Results DUI n Crash-involved drivers who were reported as suspected DUI had 2.3 times greater risk of TBI n Males ages 15-44 were 70% TBI’s suspected DUI
8
Selected Results Urban vs. Rural Crashes n Crashes in rural areas had 1.5 times greater risk of TBI than crashes in urban areas n Collisions with fixed objects were 44% of rural TBI crashes, and to 28% of urban TBI crashes n Unsafe speed was the primary contributing human factor in 24% of rural TBI crashes, 13.5% urban. n Alcohol involvment was the primary contributing human factor in 14% of rural TBI crashes, 10% urban.
9
Selected Results Elderly Drivers n Drivers 65 and over had 1.9 times greater risk of TBI than drivers under 65 n Driver inattention and failure to yield right of way were 52% of primary contributing human factors for drivers 65 and over, and 21% for drivers under 65. n Unsafe speed and alcohol involvement were 37% of primary contributing human factors for drivers under 65, and 4.5% for drivers 65 and over.
10
Kentucky TBI Surveillance System Proposal n Kentucky crash data n Emergency department data (UB92) n Mental health and retardation n Rehabilitation n Medicaid The proposed system would incorporate the following data sets, in addition to those already being linked (hospital inpatients, death certificates, and trauma registries)
