To assess patients' views of maximum acceptable waiting times (MAWT) for hip and knee replacement, associated factors and the accuracy of self-reported waiting times.
We mailed 1000 questionnaires each to two random samples of patients either waiting for or who had received an arthroplasty within the preceding 3-12 months. We used linear regression to assess the determinants of patient MAWT, and content analysis to assess reasons for MAWT and ideal waiting time.
Of the 1330 responses, 1127 had MAWT data. The sample was 57% women; mean age was 70 +/- 11 years. Median self-reported and actual waiting time was eight months (Spearman correlation = 0.70). Median MAWT was four months and ideal waiting time was two months. The most frequent reasons for MAWT were pain, quality of life and needing time to prepare for surgery. A longer MAWT was associated with younger age, group (waiting), a longer self-reported waiting time, better EQ-5D index, an acceptable waiting time, a perception of fairness and a view that others worse off on the list should go ahead.
Patients' views of acceptable waiting times are important for a fair process of establishing waiting time benchmarks for joint replacement.
评估患者对髋关节和膝关节置换术的最长可接受等待时间（MAWT）的看法、相关因素以及自我报告等待时间的准确性。
我们向两个随机抽取的患者样本各邮寄了1000份问卷，这些患者要么正在等待关节置换术，要么在过去3至12个月内接受了关节置换术。我们使用线性回归评估患者MAWT的决定因素，并使用内容分析评估MAWT的原因和理想等待时间。
在1330份回复中，1127份有MAWT数据。样本中女性占57%；平均年龄为70±11岁。自我报告的等待时间中位数和实际等待时间中位数为8个月（斯皮尔曼相关性=0.70）。MAWT中位数为4个月，理想等待时间为2个月。MAWT最常见的原因是疼痛、生活质量以及需要时间为手术做准备。较长的MAWT与年龄较小、组别（等待中）、自我报告的等待时间较长、EQ-5D指数较好、可接受的等待时间、公平感以及认为排在名单上情况更糟的其他人应该先进行手术有关。
患者对可接受等待时间的看法对于公平地确定关节置换术等待时间基准的过程很重要。
