The importance of expectations has been assessed by giving 88 patients who had undergone total hip replacement surgery a series of visual analogue scales to provide a pain score, a 5-point rating scale to assess their remembered expectations, and an interview to establish clinical, functional, social, and psychological data. Patients generally had high expectations, but only 55% had their expectations fulfilled. Despite this, 86% claimed the operation to be successful, though when questioned more closely patients noted a certain amount of displeasure about the outcome. Further analysis revealed that, when the sample was split into 2 groups of fulfilled and unfulfilled expectations, significant differences were noted in that the quality of life enjoyed by the former group was greater than that enjoyed by the latter group. This finding suggests that the notion of 'success' is not as effective as the notion of 'expectations' as a measure of the outcome of total hip replacement surgery.
通过让88位接受了全髋关节置换手术的患者使用一系列视觉模拟量表来提供疼痛评分、用一个5分制量表来评估他们记忆中的期望，并通过访谈来获取临床、功能、社会和心理数据，期望的重要性得到了评估。患者通常期望很高，但只有55%的患者期望得到了满足。尽管如此，86%的患者声称手术是成功的，不过当被进一步追问时，患者们指出对结果存在一定程度的不满。进一步分析表明，当样本被分为期望得到满足和未得到满足的两组时，发现了显著差异，即前一组所享有的生活质量高于后一组。这一发现表明，作为全髋关节置换手术结果的衡量标准，“成功”的概念不如“期望”的概念有效。
