Globally, every 25 seconds, a person dies in a motor vehicle crash (MVC) and 58 people get injured. Adding to the rising distracted-driving rates is the rapid growth of the number of cars in circulation globally. This study examined the proportion of distracted drivers among patients attending orthopaedic fracture clinics, as well as associated factors.
In this large, multicenter, cross-sectional study, we recruited 1,378 patients across 4 Canadian fracture clinics. Eligible patients completed an anonymous questionnaire about distracted driving. We calculated the percentages of specific distractions. Using questionnaire responses and published crash risk odds ratios (ORs), patients were grouped as distraction-prone and distraction-averse. Regression analyses to determine the association of demographic characteristics with distracting behaviors and the odds of being in a distraction-related crash were performed.
In total, 1,358 patients (99.7%) self-reported distracted driving. Prevalent distractions included talking to passengers (98.7%), distractions outside the vehicle (95.5%), listening to the radio (97.6%), adjusting the radio (93.8%), and daydreaming (61.2%). Of the 1,354 patients who acknowledged mobile phone distractions, 889 (65.7%) accepted phone calls and continued driving, 675 (49.8%) read electronic messages, and 475 (35.1%) sent electronic messages. Younger age (OR, 0.94 [95% confidence interval (CI), 0.91 to 0.97]; p < 0.001) and household incomes of $80,000 to <$100,000 (OR, 1.92 [95% CI, 1.17 to 3.14]; p = 0.01) and ≥$100,000 (OR, 2.48 [95% CI, 1.57 to 3.91]; p < 0.001) were associated with being in the distraction-prone group. Distraction-prone patients were twice as likely to be in a distraction-related MVC (OR, 1.98 [95% CI, 1.43 to 2.74]; p < 0.001). Of 113 drivers who sustained injuries from MVCs, 20 (17.7%) acknowledged being distracted. Of 729 patients who reported being the driver in a previous MVC in their lifetime, 226 (31.0%) confirmed being distracted.
This survey-based study showed that driving distractions were near universally acknowledged. The pervasiveness of distractions held true even when only the more dangerous distractions were considered. One in 6 patients in MVCs reported being distracted in their current crash, and 1 in 3 patients disclosed being distracted in an MVC during their lifetime.
在全球范围内，每 25 秒就有一人死于机动车碰撞事故（MVC），58 人受伤。造成分心驾驶率上升的原因是全球汽车保有量的快速增长。本研究调查了在骨科骨折诊所就诊的患者中分心驾驶的比例，以及相关因素。
在这项大型、多中心、横断面研究中，我们在加拿大的 4 家骨折诊所招募了 1378 名患者。合格的患者完成了一份关于分心驾驶的匿名问卷。我们计算了特定干扰因素的百分比。使用问卷回答和已发表的碰撞风险比值比（OR），将患者分为易分心和不易分心两组。进行回归分析以确定人口统计学特征与分散行为的关联，以及与分心相关的碰撞的可能性。
共有 1358 名患者（99.7%）报告了分心驾驶。常见的干扰因素包括与乘客交谈（98.7%）、车外干扰（95.5%）、听收音机（97.6%）、调整收音机（93.8%）和白日梦（61.2%）。在承认手机分心的 1354 名患者中，889 名（65.7%）接了电话并继续开车，675 名（49.8%）阅读了电子信息，475 名（35.1%）发送了电子信息。年龄较小（OR，0.94[95%置信区间（CI），0.91 至 0.97]；p<0.001）和家庭收入为 80000 至<100000 加元（OR，1.92[95%CI，1.17 至 3.14]；p=0.01）和≥100000 加元（OR，2.48[95%CI，1.57 至 3.91]；p<0.001）与处于易分心组相关。易分心的患者发生与分心相关的 MVC 的可能性是对照组的两倍（OR，1.98[95%CI，1.43 至 2.74]；p<0.001）。在 113 名因 MVC 受伤的驾驶员中，有 20 名（17.7%）承认分心。在报告一生中曾发生过 MVC 的 729 名患者中，有 226 名（31.0%）确认分心。
这项基于调查的研究表明，驾驶分心几乎普遍被承认。即使只考虑更危险的干扰因素，干扰的普遍性也是如此。在 MVC 中，每 6 名患者中就有 1 名报告分心，每 3 名患者中就有 1 名在 MVC 期间承认分心。
