With the increasing need for disease-specific health outcome measurements, the Oxford hip score was developed to measure health-related quality of life of total hip arthroplasty (THA) patients in the United Kingdom. The Oxford hip score comprises 12 items pertaining to pain and physical function, which are increasingly used to measure health outcomes of patients who have undergone THA. The purpose of this study was to establish the validity and responsiveness of the Oxford hip score in a prospective study of Japanese patients.
The study was conducted at two hospitals. The eligibility criterion for the study was consenting adult patients who underwent primary unilateral THA between April 2005 and October 2007. Three scales were self-administered at the preoperative stage and 6 months after THA. These scales were the Oxford hip score, the Short Form-36 (SF-36) version 2, and three activities requiring deep flexion of the hip (i.e., clipping one's toenails; use of a Japanese squat toilet; "seiza"--sitting on one's legs on the floor, a common posture while eating in Japan.
A total of 224 consenting adult patients were recruited. Among them, 125 (61.9%) participated in pre- and postoperative surveys. Altogether, 108 (22 men, 86 women; mean age, 58.4 +/- 12.5 years) of the 125 patients answered all the items. A significant improvement in the mean scores was observed in all scales. Correlation coefficients between the Oxford hip score and the SF-36 version 2 (physical functioning, role physical, bodily pain) ranged from 0.60 to 0.76 preoperatively and postoperatively. Effect size was 1.7 for pain and 1.3 for physical function. The effect size for seiza was small (0.3).
This study demonstrated the validity and responsiveness of the Oxford hip score in a prospective study. However, it does not measure activities requiring deep flexion of the hip joint, and the use of additional items is suggested.
随着对特定疾病健康结局测量需求的增加，牛津髋关节评分被开发出来用于评估英国全髋关节置换术（THA）患者与健康相关的生活质量。牛津髋关节评分由12项有关疼痛和身体功能的项目组成，越来越多地用于测量接受THA患者的健康结局。本研究的目的是在前瞻性研究日本患者中确立牛津髋关节评分的有效性和反应性。
该研究在两家医院进行。研究的纳入标准是2005年4月至2007年10月间接受初次单侧THA的成年患者。在术前阶段和THA后6个月由患者自行填写三个量表。这些量表分别是牛津髋关节评分、简短健康调查问卷（SF - 36）第2版，以及三项需要髋关节深度屈曲的活动（即剪脚趾甲；使用日式蹲厕；“正坐”——双腿盘坐在地上，这是日本用餐时常见的姿势）。
共招募了224名成年患者。其中，125名（61.9%）参与了术前和术后调查。125名患者中共有108名（22名男性，86名女性；平均年龄58.4±12.5岁）回答了所有项目。所有量表的平均得分均有显著改善。术前和术后牛津髋关节评分与SF - 36第2版（生理功能、躯体角色功能、躯体疼痛）之间的相关系数在0.60至0.76之间。疼痛的效应量为1.7，身体功能的效应量为1.3。正坐的效应量较小（0.3）。
本前瞻性研究证明了牛津髋关节评分的有效性和反应性。然而，它未对需要髋关节深度屈曲的活动进行测量，建议使用额外的项目。
