The Numeric Rating Scale (NRS-11) has been widely used clinically for the assessment of pain. Its use for clinical research is controversial. Reports differ as to whether or not the NRS-11 should be treated as a ratio pain measurement tool. This study compared the NRS-11 to a ratio measure for pain assessment: the visual analog scale (VAS). Simultaneous pain measurements using these 2 scales were compared in clinical situations commonly encountered in a tertiary community hospital. Whereas linear relationships were noted in laboring patients and in postoperative patients with thoracic or abdominal incisions during cough, no such correlations were noted for the same postoperative patients at rest or for postoperative orthopedic patients. The NRS-11 should not be considered to be interchangeable with the VAS. Its use for clinical research should be limited to situations where it has specifically demonstrated linear properties.
数字评定量表（NRS-11）在临床上已被广泛用于疼痛评估。其在临床研究中的应用存在争议。关于NRS-11是否应被视为一种比率性疼痛测量工具，各报告说法不一。本研究将NRS-11与一种用于疼痛评估的比率测量方法：视觉模拟量表（VAS）进行了比较。在一家三级社区医院常见的临床情况下，对使用这两种量表同时进行的疼痛测量进行了比较。虽然在分娩患者以及胸部或腹部有切口的术后患者咳嗽时发现了线性关系，但对于同样的术后患者休息时或术后骨科患者，未发现此类相关性。NRS-11不应被视为可与VAS互换。其在临床研究中的应用应限于已明确证明具有线性特性的情况。
