AIM
The American Academy of Pediatrics and the European Centre for Pediatric and Adolescent Medicine guideline define fever as a temperature >38.0°C for all ages and recommend use of rectal thermometers in children <3 years. Based on new literature, this definition of fever using a fixed threshold of 38.0°C needs to be re-examined.
DESIGN
A multi-site diagnostic accuracy study was conducted to compare an "age-based" threshold model with a "fixed" threshold over 38.0°C on a total of 894 patients of which 373 were ill.
METHODS
The "age-based" and "fixed" threshold fever determinations were then compared to a clinical categorization ("well" or "ill") conducted by a clinician through a comprehensive examination.
RESULTS
The sensitivity and accuracy for the age-based thresholds were found to be superior to the fixed thresholds in all ages and current ear thermometers were found equivalent to rectal thermometers in infants <6 months.
目的
美国儿科学会和欧洲儿童和青少年医学中心指南将发热定义为所有年龄段的体温>38.0°C，并建议在<3 岁的儿童中使用直肠温度计。基于新的文献，使用固定阈值 38.0°C 的发热定义需要重新审查。
设计
一项多地点诊断准确性研究比较了总共 894 名患者（其中 373 名患病）的“基于年龄”阈值模型与超过 38.0°C 的“固定”阈值，其中 373 名患病。
方法
然后将“基于年龄”和“固定”阈值的发热与临床医生通过全面检查进行的临床分类（“健康”或“患病”）进行比较。
结果
发现基于年龄的阈值在所有年龄段的敏感性和准确性均优于固定阈值，并且在<6 个月的婴儿中，当前的耳温计与直肠温度计等效。
