Motorcycles are a common mode of transport, especially in low-middle-income countries like Pakistan. The pattern and severity of injuries in motorcycle trauma depends on the mechanism of accident, which may be classified as collision accidents (CAs) or loss-of-control accidents (LOCAs). In this study, we aimed to investigate patterns of trauma due to motorcycle CAs and LOCAs, with a focus on injuries, management, complications, and outcomes.
A retrospective cohort study was conducted at the Aga Khan University Hospital (AKUH), Pakistan (a level 1 trauma facility), enrolling all patients presenting with motorcycle trauma between January 2018 and March 2019.
The most common sites of major injury were the lower limb (40.9%), head and neck (38.1%), and upper limb (27.5%). A significantly higher percentage of CA victims had head and neck injuries (43.4% vs. 30.5%), abdominal injuries (5.5% vs. 1.1%), pelvic fracture (5.9% vs. 0%), and polytrauma (22.8% vs. 11.1%). Compared to LOCA victims, CA victims had a significantly higher incidence of acute kidney injury (AKI; 25.7% vs. 15.8%; < .011), longer hospital lengths of stay (LOSs; 3 [2-6] days vs. 2.5 [2-4] days; = .019), and long-term disability ( = .002). When adjusted for age and gender on multivariable logistic regression with mechanism of accident as the dependent variable, CA was significantly associated with male gender (odds ratio [OR] = 2.045, 95% confidence interval [CI] [1.038-4.026]), abdominal injury (OR = 5.748, 95% CI [1.285-25.702]), head and neck injury (OR = 1.492, 95% CI [1.007-2.211]), polytrauma (OR = 2.368, 95% CI [1.383-4.055]), AKI (OR = 1.937, 95% CI [1.183-3.171]), and LOS (OR = 1.041, 95% CI [1.004-1.079]).
Though both motorcycle CAs and LOCAs stress trauma systems in developing countries, the dynamics of CAs mean that they result in worse injuries and outcomes. Specific measures to reduce CAs and LOCAs are urgently indicated in developing countries to reduce the burden of morbidity and mortality of motorcycle accidents.
摩托车是一种常见的交通工具，尤其在巴基斯坦等中低收入国家更为常见。摩托车事故造成的伤害模式和严重程度取决于事故机制，可分为碰撞事故（CA）和失去控制事故（LOCA）。本研究旨在探讨因 CA 和 LOCA 导致的摩托车创伤模式，重点关注损伤、处理、并发症和结局。
这是一项在巴基斯坦 Aga Khan 大学医院（AKUH，一级创伤中心）进行的回顾性队列研究，纳入 2018 年 1 月至 2019 年 3 月期间因摩托车创伤就诊的所有患者。
最常见的主要损伤部位是下肢（40.9%）、头颈部（38.1%）和上肢（27.5%）。CA 受害者的头颈部损伤（43.4% vs. 30.5%）、腹部损伤（5.5% vs. 1.1%）、骨盆骨折（5.9% vs. 0%）和多发伤（22.8% vs. 11.1%）的比例显著更高。与 LOCA 受害者相比，CA 受害者的急性肾损伤（AKI；25.7% vs. 15.8%； < .011）、住院时间（LOS）更长（3 [2-6] 天 vs. 2.5 [2-4] 天； = .019）和长期残疾（ = .002）的发生率更高。在校正年龄和性别后，采用多变量逻辑回归，以事故机制为因变量，CA 与男性（比值比 [OR] = 2.045，95%置信区间 [CI] [1.038-4.026]）、腹部损伤（OR = 5.748，95% CI [1.285-25.702]）、头颈部损伤（OR = 1.492，95% CI [1.007-2.211]）、多发伤（OR = 2.368，95% CI [1.383-4.055]）、AKI（OR = 1.937，95% CI [1.183-3.171]）和 LOS（OR = 1.041，95% CI [1.004-1.079]）显著相关。
尽管摩托车 CA 和 LOCA 都对发展中国家的创伤系统造成压力，但 CA 的动态意味着它们会导致更严重的损伤和结局。发展中国家迫切需要采取具体措施来减少 CA 和 LOCA，以降低摩托车事故发病率和死亡率的负担。
