The U.S. prison population has increased substantially in recent years, and violent injury is common among prisoners. We sought to describe injury patterns and other characteristics of prisoners who presented to a trauma center after injury. Because penetrating trauma from an improvised weapon (e.g., shank) is frequent, we also sought to compare characteristics and outcomes of prisoners and non-prisoners who sustained an anterior abdominal stab or shank wound (AASW).
We analyzed injured adult prisoners who presented to a Level 1 trauma center between February, 2011, and April, 2017. We described characteristics of the injured prisoners and their hospitalizations. We compared prisoners who sustained an AASW to a random sample of non-prisoners with the same mechanism of injury using the chi-square test, Student's t-test, and logistic and Poisson regression.
Of 14,461 hospitalized injured adults, 299 (2.0%) were injured while incarcerated. 185 (62%) encounters involved interpersonal violence and 36 prisoners (12%) presented with self-inflicted injuries. 98 (33%) had a psychiatric disorder. Among 33 prisoners and 66 non-prisoners who sustained an AASW, prisoners were less likely to have undergone a laparotomy [14/33 (42%) vs 44/66 (67%); RR 0.64 (95% CI 0.41-0.98)] or sustained an injury requiring operative intervention [2/33 (6%) vs 23/66 (35%); RR 0.17 (95% CI 0.04-0.69)].
Many injured prisoners have psychiatric illness, are involved in interpersonal violence, or harm themselves. Among hospitalized patients, abdominal stab/shank wounds sustained in prison are less likely to result in significant injuries or operative intervention than similar wounds in non-prisoners.
近年来，美国监狱人口大幅增加，囚犯中常见暴力伤害。我们旨在描述受伤后到创伤中心就诊的囚犯的受伤模式和其他特征。由于常见由简易武器（如注射器）造成的穿透性创伤，我们还试图比较遭受前腹部刺伤或注射器刺伤的囚犯和非囚犯的特征和结局。
我们分析了 2011 年 2 月至 2017 年 4 月期间到一级创伤中心就诊的成年受伤囚犯。我们描述了受伤囚犯及其住院的特征。我们使用卡方检验、学生 t 检验、逻辑回归和泊松回归比较了遭受前腹部刺伤或注射器刺伤的囚犯和具有相同损伤机制的随机非囚犯样本。
在 14461 名住院受伤成年人中，299 名（2.0%）在监禁期间受伤。185 次（62%）涉及人际暴力，36 名囚犯（12%）为自残。98 名（33%）有精神障碍。在 33 名囚犯和 66 名非囚犯中，接受了剖腹手术的囚犯比例较低[33/33（100%）比 66/66（100%）；RR1.00（95%CI1.00-1.00）]，需要手术干预的受伤比例也较低[2/33（6%）比 23/66（35%）；RR0.07（95%CI0.02-0.26）]。
许多受伤的囚犯有精神疾病，涉及人际暴力或自残。在住院患者中，监狱中发生的腹部刺伤/注射器刺伤导致严重损伤或手术干预的可能性低于非囚犯中发生的类似损伤。
