The objective of this study was to evaluate the performance of the Haemoglobin Colour Scale, developed by Stott and Lewis, to diagnose anaemia in a primary health care setting where anaemia was prevalent and severe. Three measures of anaemia were compared in 535 preschool children: haemoglobin based on the Haemoglobin Colour Scale, clinical assessment in three sites (conjunctiva, palm and nail bed) and haemoglobin based on a digital haemoglobinometer (HemoCue method) taken as gold standard. A statistically significant correlation (r = 0.80, coefficient = 0.77 and Y intercept = 2.33) was obtained between the results of the Haemoglobin Colour Scale and the HemoCue. In more than 80% of cases, the difference between the colour scale readings and the results of the HemoCue was within 1 g/dl. Of 415 anaemic children (Hb < 11 g/dl by HemoCue), 85.2% were so identified by the Haemoglobin Colour Scale and 19.7% were classified anaemic by clinical pallor. Of 19 severely anaemic children (Hb < 7 g/dl by HemoCue), 73.6% were identified as severely anaemic and 100% were classified as anaemic by the colour scale, 61.1% were classified as anaemic using clinical pallor. We found the Haemoglobin Colour Scale to be a useful tool in identifying anaemic and severely anaemic children. Efficiencies in term of cost, accuracy and time make it an important resource in primary health care settings in developing countries. Further testing with other staff in other settings is recommended to determine the usefulness of large-scale distribution.
本研究的目的是评估由斯托特和刘易斯开发的血红蛋白比色卡，在贫血普遍且严重的初级卫生保健环境中诊断贫血的性能。对535名学龄前儿童的三种贫血测量方法进行了比较：基于血红蛋白比色卡的血红蛋白、三个部位（结膜、手掌和甲床）的临床评估以及以数字血红蛋白仪（HemoCue法）测量的血红蛋白作为金标准。血红蛋白比色卡结果与HemoCue结果之间存在统计学显著相关性（r = 0.80，系数 = 0.77，截距 = 2.33）。在超过80%的病例中，比色卡读数与HemoCue结果之间的差异在1 g/dl以内。在415名贫血儿童（HemoCue法测得Hb < 11 g/dl）中，85.2%通过血红蛋白比色卡被识别为贫血，19.7%通过临床面色苍白被归类为贫血。在19名重度贫血儿童（HemoCue法测得Hb < 7 g/dl）中，73.6%被比色卡识别为重度贫血，100%被比色卡归类为贫血，61.1%通过临床面色苍白被归类为贫血。我们发现血红蛋白比色卡是识别贫血和重度贫血儿童的有用工具。在成本、准确性和时间方面的效率使其成为发展中国家初级卫生保健环境中的重要资源。建议在其他环境中与其他工作人员进行进一步测试，以确定大规模分发的实用性。
