Characterization of Fatal Injuries in Oil and Gas Industry-Related Helicopter Accidents in the Gulf of Mexico, 2004–2014
Abstract Background: Transportation events are the most common cause of offshore fatalities in the oil and gas industry, and helicopter accidents comprise the majority of transportation events. Little is known about injury distributions in civilian helicopter crashes, and helicopter passengers continue to die in crashes that are considered survivable. Knowledge of injury distributions could focus research and recommendations for injury prevention and post-crash survival. The objective of this study was to describe the distribution of injuries among fatalities in oil and gas industry-related helicopter accidents in the Gulf of Mexico. Methods: Pilots and passengers of accidents during 2004–2014 were identified from government records and media reports. Autopsy reports were requested from the responsible jurisdictions. Each documented injury was coded using the Abbreviated Injury Scale (AIS), and frequency and proportion of injuries by AIS body region and severity were calculated. Injuries were also categorized into more detailed body regions to identify focused areas of prevention and control. Results: Minor injuries were most prevalent in the face, neck, upper and lower extremities, and abdomen. Serious or worse injuries were most prevalent in the thorax, spine, head, and external/other regions. The most frequent injuries by detailed body regions were thoracic organ, thoracic skeletal, abdominal organ, and leg injuries. Drowning occurred in 37.1% of victims.Conclusions: The proportion of minor, moderate, and severe or worse injuries differed by body region, and the most frequent injuries occurred in the thorax and lower extremity regions.
