A 10-Year Profile of Trauma Admissions Caused by Interpersonal Violence: A Major Trauma Centre's Experience

ABSTRACT

<p><b>INTRODUCTION</b>This study aimed to characterise interpersonal violence victims admitted to a major trauma centre.</p><p><b>MATERIALS AND METHODS</b>A retrospective cohort study of interpersonal violence victims who were admitted to our centre from 1 January 2001 to 31 December 2010 was conducted. Data were obtained from our trauma registry.</p><p><b>RESULTS</b>Interpersonal violence victims constituted 444 (90.1% males and 9.9% females) out of a total of 8561 trauma admissions in the same time period. The average age was 36.6 years (range, 14 to 83 years). Majority were Chinese (53.4%) and Singaporeans (77.3%). The number of cases increased from 10 per year to 96 per year in the first 8 years, then decreased in the last 2 years (55 in year 2010). Time of injury was predominantly 0000 to 0559 hours (72.3%). Interpersonal violence mostly occurred in public spaces for both genders (88.7%). However, the number of females who were injured at home was significantly higher than males (P = 0.000). Blunt trauma (58.3%) was more common than penetrating trauma (41.7%). The average injury severity score (ISS) was 13.5 (range, 1 to 75); 34.9% of patients had major trauma (ISS >15). The average Glasgow coma scale (GCS) score was 13.5 (range, 3 to 15); 16.4% of patients had moderate-to-severe brain injury (GCS 3-8). Blunt trauma was significantly more likely to cause major trauma than penetrating trauma (P = 0.003). The sole case of firearm assault caused most morbi-mortality. Overall mortality was 4.5%. Major trauma (OR 25.856; P = 0.002) and moderate-to-severe brain injury (OR 7.495; P = 0.000) were independent risk factors of mortality.</p><p><b>CONCLUSION</b>There has been no prior published data on interpersonal violence locally. This study is thus useful as preliminary data for future population-based studies. It also provides data for authorities to formulate preventive and intervention strategies.</p>
