OBJECTIVES
The objective was to assess in a pediatric emergency department (ED) the reliability of the color analog scale (CAS) for acute pain assessment, overall and between traumatic and nontraumatic pain etiology.
METHODS
This was a prospective study of children aged 5 to 16 years in the ED of a children's hospital who had a complaint of pain. The CAS was administered to the patient at admission and at 30 minutes. To evaluate repeatability, a second measurement was obtained 1 minute following each assessment. This assumed there would be no substantial change in pain intensity within 1 minute. The authors used the intraclass correlation coefficient (ICC) to evaluate the repeatability of 1-minute interval measurements.
RESULTS
A total of 170 patients were enrolled. The origin of pain was traumatic in 81 cases (48%). Regardless of pain etiology, the CAS scores were highly repeatable (r = 0.97, 95% confidence interval [CI] = 0.95 to 0.98).
CONCLUSIONS
The color analog scale is both a valid and a reliable self-reporting tool in the assessment of acute pain in children.
目的
评估在儿科急诊科使用颜色模拟量表（CAS）评估急性疼痛的可靠性，包括总体可靠性以及在创伤性和非创伤性疼痛病因之间的可靠性。
方法
这是一项针对儿童医院急诊科5至16岁有疼痛主诉儿童的前瞻性研究。在入院时和30分钟时对患者使用CAS。为评估重复性，在每次评估后1分钟进行第二次测量。这是假设在1分钟内疼痛强度不会有实质性变化。作者使用组内相关系数（ICC）来评估1分钟间隔测量的重复性。
结果
共纳入170例患者。81例（48%）疼痛起源于创伤。无论疼痛病因如何，CAS评分的重复性都很高（r = 0.97，95%置信区间[CI] = 0.95至0.98）。
结论
颜色模拟量表在评估儿童急性疼痛方面是一种有效且可靠的自我报告工具。
