OBJECTIVE: The study aimed to estimate the incidence, prevalence and disability-adjusted life years (DALY) for traumatic brain injury (TBI) in New Zealand (NZ) in 2010. METHODS: A multi-state life table model was constructed using inputs from the Brain Injury Outcomes New Zealand in the Community study for the first-ever incidence of TBI in a lifetime and its severity distribution, from the NZ Ministry of Health's Mortality Collection for the data on TBI mortality and from Statistics of NZ for the population data. The modeled estimate of prevalence was combined with the disability weights for TBI (by stage and severity level) from the Global Burden of Disease 2010 study to obtain estimates of health loss (DALYs) for TBI. RESULTS: Approximately, 11,300 first-ever incident TBIs occurred in NZ during 2010, with 527,000 New Zealanders estimated to have ever experienced a TBI (prevalent cases). The estimated 20,300 DALYs attributable to TBI accounted for 27% of total injury-related health loss and 2.4% of DALYs from all causes. Of the total DALYs attributable to TBI, 71% resulted from fatal injuries. However, non-fatal outcomes accounted for a substantial share of the burden (29%) with mild TBI making the greater contribution of non-fatal outcomes (56%). CONCLUSIONS: The burden of TBI in NZ is substantial, and mild TBI contributes to a major part of non-fatal outcomes.
