Trauma system developments reduce mortality in hospitalized trauma patients in Al-Ain City, United Arab Emirates, despite increased severity of injury

Background Trauma is a leading cause of death in the United Arab Emirates (UAE). There have been major developments in the trauma system in Al-Ain City during the last two decades. We aimed to study the effects of these developments on the trauma pattern, severity, and clinical outcome of hospitalized trauma patients in Al-Ain City, United Arab Emirates. Methods This is a retrospective analysis of two separate sets of prospectively collected trauma registry data of Al-Ain Hospital. Data were collected over two periods: from March 2003 to March 2006 and from January 2014 to December 2017. Demography, injury mechanism, injury location, and clinical outcomes of 2573 trauma patients in the first period were compared with 3519 patients in the second period. Results Trauma incidence decreased by 38.2% in Al-Ain City over the last 10 years. Trauma to females, UAE nationals, and the geriatric population significantly increased over time (p< 0.0001, Fisher's exact test for each). Falls on the same level significantly increased over time, while road traffic collisions and falls from height significantly decreased over time (p< 0.0001, Fisher's exact test for each). Mortality significantly decreased over time (2.3% compared with 1%,p< 0.0001, Fisher's exact test). Conclusions Developments in the trauma system of our city have reduced mortality in hospitalized trauma patients by 56% despite an increased severity of injury. Furthermore, the injury incidence in our city decreased by 38.2% over the last decade. This was mainly in road traffic collisions and work-related injuries. Nevertheless, falls on the same level in the geriatric population continue to be a significant problem that needs to be addressed.
