OBJECTIVE
To evaluate the reliability and the validity of the use of simple clinical signs as a method of anemia detection.
METHODS
The study was carried out in a S o Paulo, Brazil, day-care center, and included 135 children from ages 3 months-6 years. Hemoglobin level results and palmar and conjunctival pallor assessment were used. Children with Hb under 11g/dl were considered as anemic; subjective criteria were used for the assessment of palmar and conjunctival pallor. Kappa statistics were used in order to verify agreement, and, in order to evaluate the technique's validity, sensitivity and specificity levels were calculated.
RESULTS
The results show low levels of agreement. There was a greater level of sensitivity to conjunctival pallor than to palmar pallor. Specificity results may be considered as good.
CONCLUSIONS
It is still early to recommend the routine use of this technique. However, it could promote substantial savings if perfected.
目的
评估使用简单临床体征作为贫血检测方法的可靠性和有效性。
方法
该研究在巴西圣保罗的一家日托中心进行，纳入了135名年龄在3个月至6岁之间的儿童。采用血红蛋白水平结果以及手掌和结膜苍白评估。血红蛋白水平低于11g/dl的儿童被视为贫血；采用主观标准评估手掌和结膜苍白。使用kappa统计量来验证一致性，并计算敏感性和特异性水平以评估该技术的有效性。
结果
结果显示一致性水平较低。结膜苍白的敏感性水平高于手掌苍白。特异性结果可认为良好。
结论
现在推荐常规使用该技术还为时过早。然而，如果加以完善，它可能会节省大量费用。
