Abstract
Traumatic brain injury (TBI) is a leading cause of death and disability among adults. Falls and motor vehicle collisions (MVCs) are the most common causes of TBI hospitalizations in Canada. The purpose of this study was to determine whether, at the provincial level, there have been significant changes in the injury rate and causes of major TBI. This was a retrospective cohort study of all patients in Nova Scotia who presented with major TBI (Abbreviated Injury Scale Head score ≥ 3) between 2002 and 2018. Prospectively entered data were collected from the Nova Scotia Trauma Registry. Annual injury rates were calculated based on 100,000 population (all ages) using population estimates from Statistics Canada. Linear regression was performed to analyze annual trends of major TBI within the province. There were 5590 major TBI patients in Nova Scotia during the 16-year study period. The overall annual rate of major TBI was 37 per 100,000 population. There was a 39% increase in the rate of major TBI over the study period (r = - 0.72, R2 = 0.51, p < 0.002). Patients had a mean age of 51 ± 25 years; 72% were male. The proportion of TBIs in males decreased significantly from 76% in 2002 to 69% in 2017 (p < 0.001). Mechanisms of injury were predominantly falls (45%) and MVCs (29%); the proportion of violent injuries was 11.5%. The rate of fall-related TBIs more than doubled between 2002 and 2017, increasing from 9.1 to 20.5 injuries per 100,000 (p < 0.001). Our findings demonstrate an increasing incidence of major TBI over a 16-year period with a greater than two-fold increase in the rate of fall-related TBI. These results are important for targeting TBI prevention efforts in reducing falls, especially in older adults.

Abstract
OBJECTIVE Traumatic brain injury (TBI)-the "silent epidemic"-contributes to worldwide death and disability more than any other traumatic insult. Yet, TBI incidence and distribution across regions and socioeconomic divides remain unknown. In an effort to promote advocacy, understanding, and targeted intervention, the authors sought to quantify the case burden of TBI across World Health Organization (WHO) regions and World Bank (WB) income groups. METHODS Open-source epidemiological data on road traffic injuries (RTIs) were used to model the incidence of TBI using literature-derived ratios. First, a systematic review on the proportion of RTIs resulting in TBI was conducted, and a meta-analysis of study-derived proportions was performed. Next, a separate systematic review identified primary source studies describing mechanisms of injury contributing to TBI, and an additional meta-analysis yielded a proportion of TBI that is secondary to the mechanism of RTI. Then, the incidence of RTI as published by the Global Burden of Disease Study 2015 was applied to these two ratios to generate the incidence and estimated case volume of TBI for each WHO region and WB income group. RESULTS Relevant articles and registries were identified via systematic review; study quality was higher in the high-income countries (HICs) than in the low- and middle-income countries (LMICs). Sixty-nine million (95% CI 64-74 million) individuals worldwide are estimated to sustain a TBI each year. The proportion of TBIs resulting from road traffic collisions was greatest in Africa and Southeast Asia (both 56%) and lowest in North America (25%). The incidence of RTI was similar in Southeast Asia (1.5% of the population per year) and Europe (1.2%). The overall incidence of TBI per 100,000 people was greatest in North America (1299 cases, 95% CI 650-1947) and Europe (1012 cases, 95% CI 911-1113) and least in Africa (801 cases, 95% CI 732-871) and the Eastern Mediterranean (897 cases, 95% CI 771-1023). The LMICs experience nearly 3 times more cases of TBI proportionally than HICs. CONCLUSIONS Sixty-nine million (95% CI 64-74 million) individuals are estimated to suffer TBI from all causes each year, with the Southeast Asian and Western Pacific regions experiencing the greatest overall burden of disease. Head injury following road traffic collision is more common in LMICs, and the proportion of TBIs secondary to road traffic collision is likewise greatest in these countries. Meanwhile, the estimated incidence of TBI is highest in regions with higher-quality data, specifically in North America and Europe.

Abstract
BACKGROUND Traumatic brain injury (TBI) is the leading cause of traumatic death and disability worldwide.We examined nationwide trends in TBI-related hospitalizations and in-hospital mortality between April 2006 and March 2011 using a nationwide, population based database that is mandatory for all hospitals in Canada. METHODS Trends in hospitalization rates for all acute hospital separations in Canada were analyzed using linear regression. Independent predictors of in-hospital mortality were evaluated using logistic regression. RESULTS Hospitalization rates remained stable for children and young adults but increased considerably among elderly adults (age Q65 years). Falls and motor vehicle collisions (MVCs) were the most common causes of TBI hospitalizations. TBIs caused by falls increased by 24% (p = 0.01), while MVC-related hospitalization rates decreased by 18% (p = 0.03). Elderly adults were most vulnerable to falls and experienced the greatest increase (29%) in fall-related hospitalization rates. Young adults (ages, 15Y24 years) were most at risk for MVCs but experienced the greatest decline (28%) in MVC-related admissions. There were significant trends toward increasing age, injury severity, comorbidity, hospital length of stay, and rate of in-hospital mortality.However, multivariate regression showed that odds of death decreased over time after controlling for relevant factors. Injury severity, comorbidity, and advanced age were the most important predictors of in-hospital mortality for TBI inpatients. CONCLUSION Hospitalizations for TBI are increasing in severity and involve older populations with more complex comorbidities. Although preventive strategies for MVC-related TBI are likely having some effects, there is a critical need for effective fall prevention strategies, especially among elderly adults.
