患者满意度在我们的现代医疗保健系统中变得更加重要。满意度的评估是困难的，因为它是一个多因素的项目，不存在黄金标准。测量满意度的潜在方法之一是使用众所周知的视觉模拟量表（VAS）。在本研究中，我们验证了VAS的满意度。在这项前瞻性研究中，我们研究了147例患者（153髋）。使用斯皮尔曼相关性检验测量结构有效性，该检验将满意度VAS与Harris髋关节评分、静息和活动期间疼痛VAS、牛津髋关节评分、简明36量表和西安大略麦克马斯特大学骨关节炎指数进行比较。信度采用组内系数进行检验。Pearson相关性检验显示相关性在0.40-0.80的范围内。满意度VAS与疼痛VAS和牛津髋关节评分之间具有高度相关性，这可能意味着疼痛是患者满意度的最重要因素之一。类内系数为0.95。满意度VAS与当前可用的主观和客观评分系统之间存在中度相关性。类内系数为0.95，表明具有良好的重测信度。VAS满意度是一种简单的工具，可以量化全髋关节置换术后患者的满意度。在本研究中，我们发现，满意度VAS具有良好的效度和信度。
Patient satisfaction becomes more important in our modern health care system. The assessment of satisfaction is difficult because it is a multifactorial item for which no golden standard exists. One of the potential methods of measuring satisfaction is by using the well-known visual analogue scale (VAS). In this study, we validated VAS for satisfaction. In this prospective study, we studied 147 patients (153 hips). The construct validity was measured using the Spearman correlation test that compares the satisfaction VAS with the Harris hip score, pain VAS at rest and during activity, Oxford hip score, Short Form 36 and Western Ontario McMaster Universities Osteoarthritis Index. The reliability was tested using the intra-class coefficient. The Pearson correlation test showed correlations in the range of 0.40–0.80. The satisfaction VAS had a high correlation between the pain VAS and Oxford hip score, which could mean that pain is one of the most important factors in patient satisfaction. The intra-class coefficient was 0.95. There is a moderate to mark degree of correlation between the satisfaction VAS and the currently available subjective and objective scoring systems. The intra-class coefficient of 0.95 indicates an excellent test–retest reliability. The VAS satisfaction is a simple instrument to quantify the satisfaction of a patient after total hip arthroplasty. In this study, we showed that the satisfaction VAS has a good validity and reliability.
