背景资料。在测量疼痛以预测未来功能时，指南仅限于最佳测量方法和可参考的时间段。以类风湿性关节炎患者为样本，研究疼痛的不同测量方法如何预测一年后的功能受限。使用基线和一年数据(n=262)进行Logistic回归分析。过去24小时的疼痛强度在0-10的数值分级范围内进行测量，最后一个月的疼痛强度使用关节炎影响测量量表2(AIMS2)中的一项进行测量。AIMS2还提供了严重疼痛的频率、疼痛综合评分和患者报告的局限性。同时还检查了医生评定的功能。综合AIMS2疼痛评分表表现最好，它预测了最大幅度的每个功能结果，疼痛评分每增加1分，预测受限几率增加21%(患者和医生的综合报告)。然而，它的组成项目-上个月剧烈疼痛的频率-也表现得差不多(几率增加了19%)。过去一个月和过去24小时的疼痛强度测量结果不一致。虽然所有的疼痛测量都预测了一些功能限制，但预测的一致性因测量而异。上个月剧烈疼痛的频率提供了简洁性和预测力之间的良好平衡。
Background. Guidance is limited on best measures and time periods to reference when measuring pain in order to predict future function.Objective. To examine how different measures of pain predict functional limitations a year later in a sample of rheumatoid arthritis patients.Methods. Logistic regression analyses were conducted using baseline and one‐year data (n= 262). Pain intensity in thelast 24 hourswas measured on a 0–10 numerical rating scale and in thelast monthusing an item from the Arthritis Impact Measurement Scale 2 (AIMS2). AIMS2 also provided frequency of severe pain, pain composite scores, and patient‐reported limitations. Physician‐rated function was also examined.Results. Composite AIMS2 pain scale performed best, predicting every functional outcome with the greatest magnitude, a one‐point increase in pain score predicting 21% increased odds of limitations (combined patient and physician report). However, its constituent item—frequency of severe pain in the last month—performed nearly as well (19% increased odds). Pain intensity measures in last month and last 24 hours yielded inconsistent findings.Conclusion. Although all measures of pain predicted some functional limitations, predictive consistency varied by measure. Frequency of severe pain in the last month provided a good balance of brevity and predictive power.
