Characteristics of fatal penetrating injury; data from a retrospective cohort study in three urban regions in the Netherlands.

ABSTRACT

INTRODUCTION: Penetrating injury (PI) is a relatively rare mechanism of trauma in the Netherlands. Nevertheless, injuries can be severe with high morbidity and mortality rates. The aim of this study is to assess fatalities due to PI and evaluate the demographic parameters, mechanism of injury and the resulting injury patterns of this group of patients in three Dutch regions. METHODS: Patients suffering fatal PI (stab- and gunshot injuries), in the period between July 1st 2013 and July 1st 2019, in the region of Amsterdam, Utrecht and The Hague were included. Data were collected from the electronic registration system (Formatus) of the regional departments of Forensic Medicine. RESULTS: During the study period 283 patients died as the result of PI. The mean age was 44 years (SD 16.9), 83% was male and psychiatric history was reported in 22%. Over 60% of the injuries were due to assault and 35% was self-inflicted. Almost half of the incidents took place at home (47%). Injuries were most frequently to the head (24%) and chest (16%). Mortality was due to exsanguination (chest 27%, multiple body region's 17%, neck 9% and extremities 8%) and traumatic brain injury (21%). Up to 40% of the patients received medical treatment, surgical intervention was performed in 25%. The injuries to the extremities suggest a (potentially) preventable death rate of over 8%. Over 70% of the total population died at the scene. CONCLUSION: Fatal PI most often involves the relatively young, male, and psychiatric patient. Self-inflicted fatal PI accounted for 35%, addressing the importance of suicide prevention programs. Identification of preventable deaths needs more awareness to reduce the number of fatal PI.
