Workplace Homicides in Northern Tunisia: A 15-Year Study (2003-2017).

Abstract

Death in workplaces remains a public health issue. However, data regarding workplace homicides are scarce in most of regions, especially in the Arab world. The aim of our study was to analyze the epidemiological features of workplace homicides in northern Tunisia. This is a descriptive study with retrospective data collection over a 15-year period (January 2003 to December 2017). We recorded 50 workplace homicide cases. Sex ratio was 49:1 (male/female). The mean age was 41.6 ± 15.13 years. Occupations the most at risk were security guards (odds ratio, 8.25; 95% confidence interval, 4.28-15.91; P < 0.0001) and taxi drivers (odds ratio, 5.61; 95% confidence interval, 2.39-13.18; P < 0.00001). The motive of the aggression was either interpersonal conflict or robbery (47.9% and 43.8%, respectively). Victims working as security guards or taxi drivers were most frequently assaulted by an unknown perpetrator, the motive being robbery. Death was most frequently secondary to blunt trauma (n = 20) or stab wounds (n = 15). Workplace homicides represent a substantial phenomenon in Tunisia. The application of prevention measures is required based on improving environmental measures targeting, in priority, security guards and taxi drivers.
