A comparative study of the injury pattern between suicidal and accidental falls from height in Northern Tunisia.

Background: Falls from height are a common cause of marbidity and mortality. The aim of this study is to examine the characteristics of the victims, the circumstances of the fall and distribution of the injuries of accidental and suicidal falls from height.
Materials and Methods: It was a retrospective cross-sectional study, based on autopsies performed over 16 years (January 2005 to December 2020). The recorded variables included demographic data of the victim, height of fall, death scene findings, length of hospital stay, autopsy findings, and toxicological results.
Results: Of the 753 victims of fall from height, 607 were fallers and 146 were jumpers. We found that male victims were predominant in the accidental group (86.8% vs. 69.2%). The mean age at death was 43.6 ± 17.9 years. Suicidal falls occurred in a private house in the majority of cases (70.5%), while accidental falls occurred most frequently at workplace (43.8%). Suicidal falls were higher than accidental falls (10.4 ± 7.3 m vs. 7.1 ± 5.7 m). Injuries in the thorax, abdomen, pelvis, upper and lower extremities were more frequentl in the suicidal falls group. Pelvic fractures were 2.1 times more likely to occur in the suicidal falls. Head injuries were more frequent in the accidental falls group. The survival delay was shorter in the suicidal falls group.
Conclusions: our study highlights the differences in the profile of the victims and in the pattern of injuries caused by falls from height, depending on the victim's intention to fall.
