Roadside pedestrian injuries represent a significant portion of trauma team activations, especially at urban trauma centers. Patient demographics and severity of injury vary greatly in this patient population. Herein, we hypothesize that injury patterns may be predictable, especially with respect to age.
All patients with roadside pedestrian injuries evaluated at our urban, level one trauma center from January 2006 through December 2008 were retrospectively reviewed. Data were collected from the institutional trauma registry. Age was used as an independent variable and compared with injury type, substance abuse, discharge setting, and mortality.
There were 226 roadside pedestrian injuries during the study period. Patients were divided into groups according to age, under 20 y, 21-40 y, 41-65 y, and over 65 y. Head injuries were more prevalent in patients over age 65, 30.4% versus 14.0% (P = 0.05). There was a trend for increasing alcohol use in the younger population. The likelihood of discharge to a rehab facility increased with age, 0%, 11.8%, 38.2%, 50.0%, respectively (P < 0.001). Mortality was significantly higher in patients older than 65 y, 15.2% versus 3.3% (P = 0.049).
Roadside pedestrian injuries have predictable injury patterns based on age. Older patients are more likely to have a head injury, longer length of stay, need for a rehab stay, and have a higher mortality. Further studies are needed to correlate precise injuries with collision mechanism and evaluate specific risk factors in this high risk population.
路边行人受伤是创伤急救团队出动的主要原因之一，尤其是在城市创伤中心。该人群的患者人口统计学和损伤严重程度差异很大。在此，我们假设损伤模式可能具有可预测性，尤其是与年龄有关。
回顾性分析了 2006 年 1 月至 2008 年 12 月在我们的城市一级创伤中心接受路边行人受伤评估的所有患者。数据从机构创伤登记处收集。年龄作为自变量，与损伤类型、药物滥用、出院地点和死亡率进行比较。
在研究期间，有 226 名路边行人受伤。患者根据年龄分为四组，年龄小于 20 岁、21-40 岁、41-65 岁和大于 65 岁。65 岁以上患者头部损伤更为常见，分别为 30.4%和 14.0%（P=0.05）。年轻患者的酒精使用量呈上升趋势。随着年龄的增长，前往康复机构的可能性增加，分别为 0%、11.8%、38.2%和 50.0%（P<0.001）。65 岁以上患者的死亡率明显更高，分别为 15.2%和 3.3%（P=0.049）。
路边行人受伤的损伤模式具有可预测性，这与年龄有关。年龄较大的患者更有可能发生头部损伤、住院时间更长、需要康复治疗，并且死亡率更高。需要进一步研究来将精确的损伤与碰撞机制相关联，并评估该高风险人群中的特定危险因素。
