Effectiveness of Integrated Trauma System Implementation on Road Traffic Fatalities and Injuries in the North of Iran Using an Interrupted Time Series Analysis

Road traffic crashes (RTCs) are a major cause of injury and death worldwide, especially in low- and middle-income countries. Integrated trauma systems (ITS) aim to reduce these injuries and deaths. This study looks at whether an ITS in Guilan, Iran, reduced RTCs, injuries, and deaths compared to a province without an ITS. The study used data from 2015 to 2019 and compared the two provinces. The results showed that the ITS in Guilan was effective in reducing RTCs, injuries, and deaths. This suggests that implementing such systems can improve road safety and public health outcomes.

• 1
  The study found that in Guilan, the daily average number of RTCs decreased significantly after the implementation of the ITS, from 38.4 to 30.8.
• 2
  In contrast, Mazandaran, the control province without ITS implementation, experienced an increase in the daily average number of RTCs from 37.29 to 42.55.
• 3
  Mortality rates in Guilan showed a marginal decline after ITS implementation, while Mazandaran demonstrated a significant increase in mortality.
