BACKGROUND The International Hip Outcome Tool 12 (iHOT-12) is a shorter version of the iHOT-33 which measures health related quality of life following treatment of hip disorders in young, active patients. The purpose of this study was identify a PASS threshold for a UK population undergoing hip arthroscopy for intra-articular hip pathology. METHODS Data was identified retrospectively from a prospective database of patients undergoing hip arthroscopy under the care of a single surgeon within the date range January 2013 to March 2017. All patients with a diagnosis of femoroacetabular impingment (FAI) undergoing arthroscopic treatment were included. iHOT-12, EuroQol 5D-5 L (EQ-5D-5 L) and a satisfaction questionnaire were available pre and post-operatively. PASS was calculated using an anchor-based approach and receiver operator characteristic (ROC) analysis. RESULTS 171 patients underwent hip arthroscopy in the study period. Linked longitudinal follow-up data was available for 122 patients (71.3%) at a median of 24.3 months (740 days, interquartile range 576-1047). The PASS threshold for the iHOT-12 was 59.5 (sensitivity 81.1%, specificity 83.9%; area under the curve (AUC) 0.92, 95% CI 0.87-0.97). 64% of patients achieved this score. The median postoperative iHOT-12 score was 72.5 (IQR 44) and the mean change in score was 35 (SD 25, p < 0.001). The EQ-5D Index improved by 0.18 (SD 0.25, p < 0.001) and there was a mean change of 7.67 (SD 24.82) on the EQ-5D VAS (p = 0.001). CONCLUSIONS We report a PASS threshold of the iHOT-12 following hip arthroscopy for FAI as a measurable benchmark for clinicians using this outcome measure.

使用12项国际髋关节预后工具评估髋关节镜检查后患者可接受的症状状态。

背景技术国际髋关节成果工具12（iHOT-12）是iHOT-33的简化版本，可在年轻活跃患者的髋部疾病治疗后测量与健康相关的生活质量。本研究的目的是确定接受髋关节镜检查以进行关节内髋关节病理检查的英国人群的PASS阈值。方法回顾性分析数据来自于前瞻性数据库，该数据库在2013年1月至2017年3月的日期范围内由一名外科医生接受髋关节镜检查，所有诊断为股髋臼撞击（FAI）的患者均接受了关节镜检查。术前和术后均提供了iHOT-12，EuroQol 5D-5 L（EQ-5D-5 L）和满意度问卷。通过基于锚的方法和接收器操作员特征（ROC）分析来计算PASS。结果研究期间有171例患者接受了髋关节镜检查。相关的纵向随访数据可用于122名患者（71.3％），中位值为24.3个月（740天，四分位间距576-1047）。iHOT-12的PASS阈值为59.5（敏感性81.1％，特异性83.9％；曲线下面积（AUC）0.92，95％CI 0.87-0.97）。64％的患者达到了该评分。术后iHOT-12得分的中位数为72.5（IQR 44），得分的平均变化为35（SD 25，p <0.001）。EQ-5D指数提高了0.18（SD 0.25，p <0.001），EQ-5D VAS的平均变化为7.67（SD 24.82）（p = 0.001）。
