The new Hypoglycaemia Error Grid (HEG). Based upon the consensus opinion of 14 consultant paediatric endocrinologists working regularly with patients with CHI in the two UK centres of excellence. In contrast to error grids designed for use in diabetes, the HEG assigned relatively low risk to missed hyperglycaemia and relatively high risk to small errors around missed hypoglycaemia. As risks did not alter beyond 4.0mmol/L, the grid was extended from 10mmol/L to 12mmol/L with the same lines to incorporate the occasional value in this range.
