Assessing Diagnostic Accuracy of Haemoglobin Colour Scale in Real-life Setting|
Shah, Pankaj P.; Desai, Shrey A.; Modi, Dhiren K. & Shah, Shobha P.
The study was undertaken to determine diagnostic accuracy of Haemoglobin Colour Scale (HCS) in hands
of village-based community health workers (CHWs) in real-life community setting in India. Participants
(501 women) were randomly selected from 8 villages belonging to a project area of SEWA-Rural, a voluntary
organization located in India. After receiving a brief training, CHWs and a research assistant obtained
haemoglobin readings using HCS and HemoCueTM (reference) respectively. Sensitivity, specificity, positive
and negative predictive-values, and likelihood ratios were calculated. Bland-Altman plot was constructed.
Mean haemoglobin value, using HCS and HemoCueTM were 11.02 g/dL (CI 10.9-11.2) and 11.07 g/dL (CI
10.9-11.2) respectively. Mean difference between haemoglobin readings was 0.95 g/dL. Sensitivity of HCS
was 0.74 (CI 0.65-0.81) and 0.84 (CI 0.8-0.87) whereas specificity was 0.84 (CI:0.51-0.98) and 0.99 (CI:0.97-
0.99) using haemoglobin cutoff limits of 10 g/dL and 7 g/dL respectively. CHWs can accurately diagnose
severe and moderately-severe anaemia by using HCS in real-life field condition after a brief training.
