Patient-reported outcomes (PROs) are an important endpoint in orthopedics providing comprehensive information about patients' perspectives on treatment outcome. Computer-adaptive test (CAT) measures are an advanced method for assessing PROs using item sets that are tailored to the individual patient. This provides increased measurement precision and reduces the number of items. We developed a CAT version of the Forgotten Joint Score (FJS), a measure of joint awareness in everyday life. CAT development was based on FJS data from 580 patients after THA or TKA (808 assessments). The CAT version reduced the number of items by half at comparable measurement precision. In a feasibility study we administered the newly developed CAT measure on tablet PCs and found that patients actually preferred electronic questionnaires over paper-pencil questionnaires.
患者报告的结局(PROs)是骨科的一个重要终点，提供了关于患者对治疗结果的综合看法。计算机自适应测试(CAT)测量是一种使用针对个体患者定制的项目集评估 PROs 的先进方法。这提供了更高的测量精度和减少了项目的数量。我们开发了一种 CAT 版本的遗忘关节评分(FJS)，这是一种日常生活中关节意识的测量方法。CAT 的开发是基于 THA 或 TKA 后 580 名患者(FJS 数据来自 808 次评估)的数据。CAT 版本在可比的测量精度下将项目数量减少了一半。在一项可行性研究中，我们在平板电脑上使用新开发的 CAT 测量方法，发现患者实际上更喜欢电子问卷而不是纸笔问卷。
