Objectives This cohort study reported descriptive statistics in athletes engaged in Summer and Winter Olympic sports who sustained a sport-related concussion (SRC) and assessed the impact of access to multidisciplinary care and injury modifiers on recovery. Methods 133 athletes formed two subgroups treated in a Canadian sport institute medical clinic: earlier (≤7 days) and late (≥8 days) access. Descriptive sample characteristics were reported and unrestricted return to sport (RTS) was evaluated based on access groups as well as injury modifiers. Correlations were assessed between time to RTS, history of concussions, the number of specialist consults and initial symptoms. Results 160 SRC (median age 19.1 years; female=86 (54%); male=74 (46%)) were observed with a median (IQR) RTS duration of 34.0 (21.0–63.0) days. Median days to care access was different in the early (1; nSRC=77) and late (20; nSRC=83) groups, resulting in median (IQR) RTS duration of 26.0 (17.0–38.5) and 45.0 (27.5–84.5) days, respectively (p<0.001). Initial symptoms displayed a meaningful correlation with prognosis in this study (p<0.05), and female athletes (52 days (95% CI 42 to 101)) had longer recovery trajectories than male athletes (39 days (95% CI 31 to 65)) in the late access group (p<0.05). Conclusions Olympic athletes in this cohort experienced an RTS time frame of about a month, partly due to limited access to multidisciplinary care and resources. Earlier access to care shortened the RTS delay. Greater initial symptoms and female sex in the late access group were meaningful modifiers of a longer RTS. Data are available on reasonable request. Due to the confidential nature of the dataset, it will be shared through a controlled access repository and made available on specific and reasonable requests.

关于奥运会运动员运动相关脑震荡的研究在哪里？关于获得多学科护理对康复的影响的描述性报告和评估


目标 本队列研究报告了参加夏季和冬季奥运会运动的遭受运动相关脑震荡 (SRC) 的运动员的描述性统计数据，并评估了获得多学科护理和伤害修正对康复的影响。方法 133 名运动员分为在加拿大体育机构医疗诊所接受治疗的两个亚组：早期（≤7 天）和晚期（≥8 天）就诊。报告了描述性样本特征，并根据访问组和伤害修正因素评估了无限制重返运动（RTS）。评估了 RTS 时间、脑震荡病史、专家咨询次数和初始症状之间的相关性。结果 观察到 160 名 SRC（中位年龄 19.1 岁；女性 = 86 (54%)；男性 = 74 (46%)），中位 (IQR) RTS 持续时间为 34.0 (21.0–63.0) 天。早期组 (1; nSRC=77) 和晚期组 (20; nSRC=83) 获得护理的中位天数不同，导致中位 (IQR) RTS 持续时间分别为 26.0 (17.0–38.5) 和 45.0 (27.5–84.5)天，分别 (p<0.001)。在本研究中，初始症状与预后存在有意义的相关性 (p<0.05)，女性运动员（52 天（95% CI 42 至 101））的恢复轨迹比男性运动员（39 天（95% CI 31 至 101））更长。 65)) 在晚期访问组 (p<0.05)。结论 该队列中的奥运会运动员经历了大约一个月的 RTS 时间，部分原因是获得多学科护理和资源的机会有限。更早获得护理缩短了 RTS 延迟。晚期接入组中更严重的初始症状和女性性别是较长 RTS 的有意义的修饰因素。可根据合理要求提供数据。 由于数据集的机密性，它将通过受控访问存储库进行共享，并根据特定和合理的请求提供。
