Abstract #107312

An evaluation of death certificate-based surveillance for traumatic brain injury — Oklahoma, 2002

In the United States, 1.4 million persons sustain a traumatic brain injury (TBI) each year at a cost of $56 billion dollars. Because death certificate data are used to estimate state and national incidence of TBI-related deaths, it is important to understand how accurate these estimates are and to identify any groups that are missed. TBI-related death was defined by narrative diagnoses associated with CDC-designated ICD-10 codes. Using probabilistic linking software, we matched death certificates with the ICD-10 codes to TBI-related death records from the Oklahoma injury surveillance system that utilizes medical examiner reports and hospital chart review. All concordant records were assumed to be cases, validated by review of a random sample. All discordant records were examined manually to determine case status. Logistic regression was used to determine the adjusted odds ratios (AOR) of being missed versus captured by death certificate-based surveillance. The model included sex, age, race, and cause of death. Overall, sensitivity of death certificate-based surveillance was 78%. Of the missed cases, the majority (62%) were due to the use of the non-specific term 'multiple trauma' as the cause of death. Death certificate surveillance was more likely to miss TBI-related deaths among persons aged ≥ 65 years (AOR=1.5; 95%C I=1.04¨C2.4); from traffic crashes (AOR=8.8; 95%CI=5.1¨C15.2); and from falls (AOR=7.1; 95%CI=3.6¨C13.7) than other categories. Death certificate surveillance underestimated TBI-related death, especially among certain groups and might lead to national underreporting of deaths. More detailed completion of death certificates would result in better estimates of TBI-related death.
