Summary

This study addresses the critical gap in reliable mortality data for road traffic injuries (RTIs) in Vietnam, where routine data collection systems are inconsistent and likely underestimate the true burden of deaths. Motivated by the high prevalence of RTIs as a leading cause of death, particularly among young males, the research aims to provide evidence-based insights into the characteristics, user patterns, seasonal distribution, and causes of RTI-related mortality to inform public health policy. The researchers utilized a national sample mortality surveillance system covering 192 communes across 16 provinces, representing approximately 3% of the Vietnamese population. Data were collected for the years 2008 and 2009. Deaths were identified through multiple commune-level sources, including health stations and administrative records, with completeness estimated using capture-recapture methods. For each identified death, verbal autopsy (VA) interviews were conducted by trained paramedical staff, and causes of death were assigned by physicians according to WHO guidelines. The study analyzed 1,061 deaths attributable to road crashes, examining demographic factors, user types, survival times, and specific causes of injury. The results revealed significant gender and age disparities, with males accounting for 79% of deaths and the 15–49 age group comprising 73% of fatalities. The age-standardized mortality rate was 33.5 per 100,000 for males and 8.5 for females. Motorcycle users represented the largest share of victims at 58%, followed by unspecified transport users (25%) and pedestrians (11%). Head injuries were the predominant cause of death, accounting for 79% of all RTI deaths where a direct cause was identified, and 78% of motorcycle-related deaths. Temporally, 80% of deaths occurred within the first day of injury, with 42% occurring before hospital arrival and 29% on-site. Seasonal peaks were observed in June and during the Lunar New Year period. The findings underscore the urgent need for improved pre-hospital first aid services and timely access to emergency care, given the high proportion of deaths occurring before medical intervention. The high mortality rate from head injuries among motorcycle users, despite mandatory helmet legislation introduced in 2007, suggests potential issues with helmet quality or enforcement that require further evaluation. The study validates verbal autopsy as a useful tool for monitoring RTI mortality in settings lacking robust civil registration systems. It concludes that sustained efforts to strengthen mortality surveillance, combined with targeted interventions for helmet effectiveness and emergency response, are essential for reducing RTI mortality in Vietnam.
