  1. Gunshot wounds : Bullet caliber is increasing.

    Article, Communication - En anglais

    Annual Meeting of the Southeastern Surgical Congress. Nashville, TN, USA, 1997/02.

    Background 

    The incidence of gunshot wounds has increased over the past two decades.

    In the past several years at our Level I trauma center in Newark NJ, we perceived that the size of ammunition involved in these wounds has been increasing as well.

    We sought to document this trend by using autopsy data as well as bullets received by surgical pathology.

    Methods 

    Measurements of bullets stored in surgical pathology were taken from alternate years between 1981 and 1993, then every year through 1997.

    A total of 745 bullets were studied in this 16-year period.

    Bullets deformed beyond measurability and shotgun pellets were excluded from the study (~20%). Linear regression of mean bullet caliber over time was performed, and analysis of variance was used to assess statistical significance of apparent differences.

    In addition, autopsy reports from the regional medical examiner's office were surveyed for description of bullet size.

    Bullet caliber, in these reports, is described as « small, » « medium, » or « large. » A total of 397 reports were studied from 1981 to 1997.

    Once again, shotgun wounds (<5%) were excluded.

    The percentage of large-caliber projectiles was plotted against time, and X2 for trend was used to determine statistical significance.

    Results 

    Results are tabulated as mean ± standard error bullet caliber (millimeters) over time.

    Linear regression reveals r=0.944, p<0.0001. (...)
