目的开发一种新的肉眼血尿评估工具--血尿分级量表（HematuriaGradingScale，HGS），并评价其在血尿样本评估中的一致性。使用标准方法，通过用盐水稀释从人血液制备30个血尿样品。20名检查者（每组5名，包括外行、护士、全科医生和泌尿科医生）参加。每个人在相同的条件下使用HGS对30个血尿样本进行评分，而不相互通信。计算组内相关系数（ICC）以评估数据集的可靠性。结果：所有检查者的ICC评分结果一致率为99.7%，95%可信区间（CI）为0.996-0.999。非专业人员组ICC值为99.3%（95% CI 0.989-0.997），护士组为98.8%（95% CI 0.980-0.994），全科医生组为99.1%（95% CI 0.984-0.995），泌尿科医生组为99.2%（95% CI 0.987-0.996）。平均Q1和Q2得分分别为4.70 +/- 0.66和4.30 +/- 1.03，表明HGS的总体满意度在所有examinator.CONCLUSION使用HGS肉眼血尿的评价是在所有类型的检查者之间的高度一致性，所有的检查者发现HGS简单，易于使用。HGS应该是评估和交流肉眼血尿的有用工具。泌尿外科82：284-289，2013。(C)2013 Elsevier Inc.
OBJECTIVE To develop a new tool for gross hematuria, the Hematuria Grading Scale (HGS), and evaluate its consistency in assessing hematuria samples.METHODS The HGS was developed on the basis of an evaluation of sample brightness and saturation using a cyan, magenta, yellow, key (black) color model. Thirty hematuria samples were prepared from human blood by diluting with saline using a standard method. Twenty examiners (5 in each group, including laypeople, nurses, general practitioners, and urologists) participated. Each scored 30 hematuria samples using the HGS under the same conditions without communicating with one another. The intraclass correlation coefficient (ICC) was calculated to assess the reliability of the datasets. Questionnaires for usefulness (Q1) and simplicity (Q2) were obtained from all examiners using a 5-point Likert scale.RESULTS The ICC for pooled examiner scores showed a high agreement rate (99.7%, 95% confidence interval [CI] 0.996-0.999). ICC values by group were 99.3% (95% CI 0.989-0.997) for laypeople, 98.8% (95% CI 0.980-0.994) for nurses, 99.1% (95% CI 0.984-0.995) for general practitioners, and 99.2% (95% CI 0.987-0.996) for urologists. Mean Q1 and Q2 scores were 4.70 +/- 0.66 and 4.30 +/- 1.03, respectively, indicating general satisfaction with the HGS among all examiners.CONCLUSION Evaluations of gross hematuria using the HGS were in high agreement among examiners of all types, and all examiners found the HGS simple and easy to use. The HGS should be a helpful tool for assessment and communication of gross hematuria. UROLOGY82: 284-289, 2013. (C) 2013 Elsevier Inc.
