Trauma surgeons have observed an increased rate of penetrating trauma during periods of increased unemployment.
During a 10-year period, the rate of unemployment in a metropolitan area was compared with the rate of intentional penetrating trauma at two Level I trauma centers. The total number of trauma cases was recorded. Assaults, derived from police records, were examined as an additional indicator of violent behavior. Pearson correlation coefficients were calculated to identify significant correlation between study variables. Stepwise maximum-likelihood estimation was used to derive a model predicting percent penetrating trauma.
The rate of unemployment and percent penetrating trauma of individuals presenting to the emergency department were significantly correlated (P = 0.014). After stepwise estimation, a model was derived (r2 = 0.846, P = 0.014) that estimated percent penetrating trauma on the basis of percent unemployment and total number of trauma admissions.
This long-term ecological study confirms that rates of penetrating trauma increase with increasing unemployment rates. This should inspire further research to identify areas of greatest need to improve delivery of resources and current public policy with the ultimate goal of decreasing the incidence of penetrating trauma.
创伤外科医生观察到在失业率上升期间穿透性创伤的发生率有所增加。
在10年期间，将一个大都市地区的失业率与两家一级创伤中心的故意穿透性创伤发生率进行比较。记录创伤病例总数。从警方记录中获取的袭击事件作为暴力行为的另一个指标进行检查。计算Pearson相关系数以确定研究变量之间的显著相关性。使用逐步最大似然估计来推导一个预测穿透性创伤百分比的模型。
急诊科就诊患者的失业率与穿透性创伤百分比显著相关（P = 0.014）。经过逐步估计，得出一个模型（r2 = 0.846，P = 0.014），该模型基于失业率百分比和创伤入院总数来估计穿透性创伤百分比。
这项长期的生态学研究证实，穿透性创伤的发生率随着失业率的上升而增加。这应促使进一步研究，以确定最需要改善资源分配和当前公共政策的领域，最终目标是降低穿透性创伤的发生率。
