To assess the accuracy of Haemoglobin Colour Scale (HCS) in identifying severely anaemic [haemoglobin (Hb) <7 g/dl] and very severely anaemic (Hb <5 g/dl) individuals, and to compare the performances of a group of health workers using HCS after training with a standard method.
The study consisted of two parts. In part 1, the performance of HCS was compared with clinical examination in a hospital population of which more than 450 individuals were severely anaemic and more than 120 very severely anaemic. Part 2 of the study was conducted in eight dispensaries where the performances of 13 health workers using the colour scale were compared with the performances of eight other health workers using clinical signs to estimate Hb.
The colour scale was 92% sensitive for both severe anaemia and very severe anaemia and performed better than clinical examination. Health workers who used the colour scale did better in identifying anaemic and severely anaemic individuals, than those who used clinical examination.
The colour scale improves health workers' capacity to identify severely anaemic individuals and could be used as a basis for referral. Although the diagnostic accuracy of the workers using HCS varied widely, in most cases they did significantly better than those who used clinical investigation alone.
评估血红蛋白比色卡（HCS）在识别重度贫血（血红蛋白（Hb）<7 g/dl）和极重度贫血（Hb <5 g/dl）个体方面的准确性，并比较一组卫生工作者在培训后使用HCS与标准方法的表现。
该研究包括两个部分。在第1部分中，将HCS的表现与一家医院中450多名重度贫血和120多名极重度贫血患者的临床检查结果进行比较。研究的第2部分在8个诊疗所进行，将13名使用比色卡的卫生工作者的表现与另外8名使用临床体征评估Hb的卫生工作者的表现进行比较。
比色卡对重度贫血和极重度贫血的敏感性均为92%，且表现优于临床检查。使用比色卡的卫生工作者在识别贫血和重度贫血个体方面比使用临床检查的卫生工作者表现更好。
比色卡提高了卫生工作者识别重度贫血个体的能力，可作为转诊的依据。尽管使用HCS的工作人员的诊断准确性差异很大，但在大多数情况下，他们的表现明显优于仅使用临床检查的人员。
