The purpose of this study was to investigate the correlation of Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference (PI) score with traditionally collected visual analog scale (VAS) scores and to determine the influence of patient demographics on PROMIS PI and VAS scores. Patient demographics were collected, and PROMIS PI, PROMIS Physical Function (PF), and VAS questionnaires were distributed to 215 patients in orthopedic ambulatory clinics. The primary outcome was correlation between PROMIS PI and VAS questionnaires. The statistical method of seemingly unrelated regressions was used to identify significant predictors and strengths of correlation between PROMIS PI and conventional forms. The PROMIS PI score was highly correlated to conventional pain and functional scores, with each standard deviation increase in PROMIS PI score predicting a 16-point increase for pain-related VAS scores (current pain, pain at rest, pain during activity, pain at night), an 18-point decrease in satisfaction of function score, and a 6-point decrease in general health score. Each standard deviation increase in PROMIS PF score for black patients predicted a reduction of 11 points for current pain, 10 points for pain at rest, 10 points for pain during activity, and 12 points for pain at night scores. The PROMIS PI score consistently predicts changes in VAS pain scores and can be considered a useful, standardized tool for measuring pain for clinical and research purposes.

本研究的目的是调查患者报告结局测量信息系统（PROMIS）疼痛干扰（PI）评分与传统收集的视觉模拟量表（VAS）评分之间的相关性，并确定患者人口统计学特征对PROMIS PI和VAS评分的影响。收集了患者的人口统计学特征，并向骨科门诊的215名患者发放了PROMIS PI、PROMIS身体功能（PF）和VAS问卷。主要结局是PROMIS PI与VAS问卷之间的相关性。采用看似不相关回归的统计方法来确定PROMIS PI与传统形式之间的显著预测因素和相关强度。PROMIS PI评分与传统疼痛和功能评分高度相关，PROMIS PI评分每增加一个标准差，与疼痛相关的VAS评分（当前疼痛、静息痛、活动时疼痛、夜间疼痛）增加16分，功能满意度评分降低18分，总体健康评分降低6分。黑人患者的PROMIS PF评分每增加一个标准差，当前疼痛评分降低11分，静息痛评分降低10分，活动时疼痛评分降低10分，夜间疼痛评分降低12分。PROMIS PI评分始终能够预测VAS疼痛评分的变化，可被视为用于临床和研究目的测量疼痛的有用的标准化工具。[《骨科》。2018年；41(6):e813 - e819。]
