Development of effective strategies for preventing concussions is a priority in all sports, including ice hockey. Digital video records of sports events contain a rich source of valuable information, and are therefore a promising resource for analysing situational factors and injury mechanisms related to concussion.
To determine whether independent raters reliably agreed on the antecedent events and mechanisms of injury when using a standardised observational tool known as the heads-up checklist (HUC) to code digital video records of concussions in the National Hockey League (NHL).
The study occurred in two phases. In phase 1, four raters (2 naïve and 2 expert) independently viewed and completed HUCs for 25 video records of NHL concussions randomly chosen from the pool of concussion events from the 2006-2007 regular season. Following initial analysis, three additional factors were added to the HUC, resulting in a total of 17 factors of interest. Two expert raters then viewed the remaining concussion events from the 2006-2007 season, as well as all digital video records of concussion events up to 31 December 2009 (n=174).
For phase 1, the majority of the factors had a κ value of 0.6 or higher (8 of 15 factors for naïve raters; 11 of 15 factors for expert raters). For phase 2, all the factors had a total percent agreement value greater than 0.8 and κ values of >0.65 for the expert raters.
HUC is an objective, reliable tool for coding the antecedent events and mechanisms of concussions in the NHL.
在所有运动项目中，包括冰球，制定预防脑震荡的有效策略是当务之急。体育赛事的数字视频记录包含了丰富的有价值信息，因此是分析与脑震荡相关的情境因素和损伤机制的有前途的资源。
确定使用一种称为抬头检查清单（HUC）的标准化观察工具对国家冰球联盟（NHL）中的脑震荡数字视频记录进行编码时，独立评估者是否在脑震荡的前因事件和损伤机制方面是否可靠地达成一致。
研究分两个阶段进行。在第一阶段，四名评估者（2 名无经验和 2 名专家）独立观看并完成了从 2006-2007 常规赛的脑震荡事件池中随机选择的 25 个 NHL 脑震荡视频记录的 HUC。在初步分析之后，HUC 中添加了另外三个因素，总共增加了 17 个感兴趣的因素。然后，两名专家评估者观看了 2006-2007 赛季的其余脑震荡事件，以及截至 2009 年 12 月 31 日的所有脑震荡事件的数字视频记录（n=174）。
对于第一阶段，大多数因素的 κ 值为 0.6 或更高（无经验评估者的 15 个因素中有 8 个；专家评估者的 15 个因素中有 11 个）。对于第二阶段，对于专家评估者，所有因素的总一致百分比值均大于 0.8，κ 值均大于 0.65。
HUC 是一种客观，可靠的工具，可用于对 NHL 中的脑震荡前因事件和机制进行编码。
