To describe injuries during a 1-day urban cycling tour.
During the May 1996 "Bike New York" tour, we monitored EMS calls to identify injuries in a cohort of helmeted cyclists shielded from traffic. We collected demographic information from entry records, injury data from ambulance call reports, and follow-up on transported patients from telephone interviews with emergency physicians. Data were summarized using proportions, relative risks (RRs), 95% confidence intervals (CIs), and chi2 RESULTS: Approximately 28,000 cyclists participated, of which 23,502 (84%) were officially registered. Sixty-eight percent of registered bicyclists were male, and 92% were between 18 and 55 years old. Of the 140 EMS calls made during the tour, 136 (97%) involved participants; this yielded an injury incidence of 5 per 1,000 riders, or 12 to 13 per 100,000 person-miles. Injury was more common among younger cyclists (RR=1.4 for age </=35 years versus age >35 years; 95% CI, 1.0 to 2.0; P <.05), and possibly women (RR=1.3; 95% CI,.9 to 1.8; P =.11). Injuries were mostly minor, but there were 7 concussions and 6 clavicle fractures; none of the 140 injuries was fatal. Thirty-eight calls resulted in ED transport, and 5 of these patients were admitted. Although EMS units were evenly distributed along the route, most EMS calls occurred in only 3 of the 7 zones (P <.001).
Injuries during the largest 1-day US cycling tour were uncommon. More data are needed to determine the relative importance of injury risk factors. Data collection during mass events may help guide distribution of EMS personnel.
描述一日城市自行车骑行之旅中的损伤情况。
在1996年5月的“纽约自行车之旅”中，我们监测了紧急医疗服务（EMS）呼叫情况，以确定一群免受交通影响的戴头盔骑行者中的损伤情况。我们从入场记录中收集人口统计学信息，从救护车呼叫报告中收集损伤数据，并通过与急诊医生的电话访谈对转运患者进行随访。数据采用比例、相对风险（RRs）、95%置信区间（CIs）和卡方进行总结。
约28,000名骑行者参与，其中23,502人（84%）正式登记。登记的骑行者中68%为男性，92%年龄在18至55岁之间。在骑行过程中拨打的140次EMS呼叫中，136次（97%）涉及参与者；这导致损伤发生率为每1000名骑行者中有5例，或每100,000人英里中有12至13例。损伤在年轻骑行者中更常见（年龄≤35岁与年龄>35岁相比，RR = 1.4；95% CI，1.0至2.0；P <.05）,女性可能也更常见（RR = 1.3；95% CI，0.9至1.8；P =.11）。损伤大多较轻，但有7例脑震荡和6例锁骨骨折；140例损伤中无一例致命。38次呼叫导致急诊转运，其中5例患者住院。尽管EMS单位沿路线均匀分布，但大多数EMS呼叫仅发生在7个区域中的3个（P <.001）。
美国最大规模一日自行车骑行之旅中的损伤并不常见。需要更多数据来确定损伤风险因素的相对重要性。大型活动期间的数据收集可能有助于指导EMS人员的分布。
