To determine the reliability of the Orthopaedic Trauma Association (OTA) Open Fracture Classification.
Video-based reliability study.
Orthopedic meetings and grand rounds.
PATIENTS/PARTICIPANTS: Orthopedic surgeons.
None.
Interobserver reliability assessment classification.
The results demonstrate the system to have high reliability and much improvement compared with published Gustilo-Anderson classification reliability studies. Overall interrater reliability (κ) values were highest for arterial injury, with near perfect agreement across all raters and within each value. Skin injury, bone loss, and contamination demonstrated moderate to substantial levels of agreement. Muscle injury had the most disagreement between raters but still demonstrating a fair level of interrater agreement, which is a level of agreement superior to the literature related to the Gustilo-Anderson classification. Levels of agreement were similar between attending surgeons and residents for all categories.
This study, which included a diverse multicenter multinational cohort of orthopaedic surgeons and residents, of the OTA Open Fracture Classification demonstrated moderate to excellent interobserver reliability.
确定骨科创伤协会（OTA）开放性骨折分类的可靠性。
基于视频的可靠性研究。
骨科会议和大查房。
患者/参与者：骨科医生。
无。
观察者间可靠性评估分类。
结果表明，该系统与已发表的 Gustilo-Anderson 分类可靠性研究相比，具有更高的可靠性和明显的改善。总体而言，动脉损伤的观察者间一致性（κ）值最高，所有评分者之间以及每个值内的一致性都非常接近完美。皮肤损伤、骨丢失和污染表现出中度至高度的一致性。肌肉损伤在评分者之间的分歧最大，但仍表现出相当程度的观察者间一致性，这一一致性水平优于与 Gustilo-Anderson 分类相关的文献。对于所有类别，主治医生和住院医生之间的一致性水平相似。
这项研究包括了来自多个骨科中心和国家的骨科医生和住院医生，他们对 OTA 开放性骨折分类进行了评估，结果表明其具有中度至极好的观察者间可靠性。
