Correction factor for the use of correctional insulin in patients with uncontrolled preprandial blood glucose

Total daily dose (units/kg/day)	Correction factor (mg/dl)a
< 0.5	50
0.5 to < 1	40
1 to < 1.5	30
1.5–2	20
> 2	Consider intravenous insulin infusion instead of correctional insulin for uncontrolled hyperglycaemia

For conversion from mg/dl  to mmol/L, divide the value in mg/dl by 18

^aCorrection factor indicates the decrease in blood glucose (mg/dl) expected with 1 unit of short-acting insulin
