To determine the reproducibility of the Brodsky grading scale and the modified 3-grade and 5-grade scales in reporting the size of the tonsils.
Retrospective review of 60 video recordings of tonsil examination by 12 independent observers with different clinical backgrounds and various levels of training. The sizes of the tonsils were graded using different grading scales.
Tertiary care university hospital.
The video recordings were chosen from an ongoing epidemiologic study of sleep-related breathing disorder in children in Hong Kong. Main Outcomes Measures The intraobserver and interobserver reproducibility of each grading scale was determined using intraclass correlation. An intraclass correlation coefficient (ICC) exceeding 0.75 was set a priori to indicate an acceptable level of reliability.
The mean intraobserver ICCs for the Brodsky grading scale and the modified 3-grade and 5-grade scales were 0.858, 0.830, and 0.865, respectively. The mean interobserver ICCs for the Brodsky grading scale and the modified 3-grade and 5-grade scales were 0.763, 0.739, and 0.783, respectively.
The Brodsky grading scale and the modified 5-grade scale achieved acceptable intraobserver and interobserver reproducibility.
确定在报告扁桃体大小时，布罗茨基分级量表以及改良的3级和5级量表的可重复性。
对12名具有不同临床背景和不同培训水平的独立观察者进行的60次扁桃体检查视频记录进行回顾性研究。使用不同的分级量表对扁桃体大小进行分级。
三级护理大学医院。
视频记录选自香港一项正在进行的儿童睡眠相关呼吸障碍的流行病学研究。主要观察指标 使用组内相关系数确定每个分级量表的观察者内和观察者间的可重复性。预先设定组内相关系数（ICC）超过0.75表示可靠性达到可接受水平。
布罗茨基分级量表以及改良的3级和5级量表的观察者内平均ICC分别为0.858、0.830和0.865。布罗茨基分级量表以及改良的3级和5级量表的观察者间平均ICC分别为0.763、0.739和0.783。
布罗茨基分级量表和改良的5级量表在观察者内和观察者间均具有可接受的可重复性。
