BACKGROUND: We performed a population-based evaluation of age-related trends in severe injury hospitalization across Canada.
METHODS: We identified hospitalizations following severe injury (Injury Severity Score [ISS] 9 15) between 2002 and 2009 using the Canadian National Trauma Registry. Age-standardized severe injury hospitalization rates were calculated using the direct method referencing the 2006 Canadian population. The annual percent change in hospitalization rates were estimated using negative binomial regression.
RESULTS: During the 8-year period, hospitalization rates for severe injury rose by 22% among individuals 65 years or older, compared with 10% among individuals younger than 65 years. Fall-related injuries accounted for 46% of all severe injury hospitalizations and increased by an average of 3% annually, with a twofold higher annual rate of increase among the elderly. Case-fatality rates declined by 10%, with the decline more than threefold higher among younger patients.
CONCLUSION: Elderly patients accounted for an increasing proportion of hospitalizations, highlighting important opportunities for injury prevention among this age group. Case-fatality rates, while declining among younger patients, remained stable in the elderly population, suggesting the need for better strategies to manage the complex care needs of these patients.
