在护理疼痛患者时，量化疼痛强度的能力是必不可少的，以便监测患者的进展和止痛效果。常用的有三种量表：简单描述量表(SDS)、视觉模拟量表(VAS)和数字(疼痛强度)评定量表(NRS)。以英语为第二语言的患者在没有翻译的情况下可能无法完成SDS，而视觉、认知或身体受损的患者可能会在使用VAS时遇到困难。在某些疾病状态下，NRS已被发现是一种简单而有效的替代方法；然而，在没有视觉线索的情况下，该量表对肿瘤患者口头实施的有效性尚未得到证实。本研究使用收敛方法检验了口头管理的0-10 NRS的效度。VAS和NRS之间有很强的相关性(r=0.847，p<；0.001)，支持口头NRS的有效性。虽然所有受试者都能够毫无困难地完成NRS和SDS，但11名受试者(20%)无法完成VAS。不能完成VAS的组的平均阿片类药物摄入量(平均170.8 mg，中位数120.0 mg，SD=135.8)明显高于VAS无困难组(平均65.6mg33.0mgSD=99.7)(Mann-Whitney检验，p=0.0065)。口头管理的0-10 NRS提供了VAS的一个有用的替代方案，特别是在通过电话与患者建立更多联系以及医院内的患者病情更严重的情况下。
The ability to quantify pain intensity is essential when caring for individuals in pain in order to monitor patient progress and analgesic effectiveness. Three scales are commonly employed: the simple descriptor scale (SDS), the visual analog scale (VAS), and the numeric (pain intensify) rating scale (NRS). Patients with English as a second language may not be able to complete the SDS without translation, and visually, cognitively, or physically impaired patients may have difficulty using the VAS. The NRS has been found to be a simple and valid alternative in some disease states; however, the validity of this scale administered verbally, without visual cues, to oncology patients has not yet been established. The present study examined validity of a verbally administered 0-10 NRS using convergence methods. The correlation between the VAS and the NRS was strong and statistically significant (r = 0.847, p < 0.001), supporting the validity of the verbally administered NRS. Although all subjects were able to complete the NRS and SDS without apparent difficulty, 11 subjects (20%) were unable to complete the VAS. The mean opioid intake was significantly higher for the group that was unable to complete the VAS (mean 170.8 mg, median 120.0 mg, SD = 135.8) compared to the group that had no difficulty with the scale (mean 65.6 mg, 33.0 mg, SD = 99.7) (Mann-Whitney test, p = 0.0065). The verbally administered 0-10 NRS provides a useful alternative to the VAS, particularly as more contact with patients is established via telephone and patients within the hospital are more acutely ill.
