Land motor vehicle-related fatal drowning in Finland: A nation-wide population-based survey

Abstract

Objective: WHO mortality statistics overlook land motor-vehicle accident (LMVA)-related drowning. The aim of the study was to provide an overview of the prevalence and trends of fatal LMVA-related drowning in Finland, plus the main crash settings, victims' demographic characteristics, and contributing factors leading to such deaths.<div>Methods: A descriptive, retrospective, population-based study of drowning deaths associated with LMVA among Finnish residents of all ages, 1971-2013. LMVA-related drownings and applicable variables were extracted from the Statistics Finland (SF) mortality database by cross-analysis of ICD injury- and external cause-of-death codes.</div><div>Results: During the study period, 538 LMVAs leading to drowning occurred among Finnish residents (2.5/1 000 000/year; 4.9% of all unintentional drownings, 3.7% of all LMVA). Three main settings, ones responsible for over 95% of LMVA-related drownings, were recognized: traffic vehicle accidents involving a passenger car; non-traffic vehicle accident involving a snowmobile; and non-traffic accidents involving agricultural, industrial, or construction vehicles. Alcohol use was a contributing factor for death in > 40% of the victims, whereas severe injuries were reported in less than 6%.</div><div>Conclusion: Because transport safety is crucial to prevent any vehicle entering the water, placing LMVA-related drowning in the category of transport accidents is warranted. Once the vehicle becomes submersed, however, prevention measures to avoid death by drowning remains decisive.</div>
