The savings were only statistically significant for patients in the improved group whose baseline HbAlc level was 10 percent or above. Measuring HbAlc is a way of measuring blood glucose levels -an important indicator for diabetics. For non-diabetics, a usual reading would be in the range 4.0-5.9 percent, for people with diabetes an HbAlc level of 6.5 percent is considered to be good control. However, this study did not take into account the cost of the intervention and, therefore, the overall cost-effectiveness could not be assessed. In a similar vein, Testa et al. ( Mun-roe et al. (
