Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The aim is to achieve tight glycaemic control with supplemental subcutaneous insulin, either Novorapid, or Actrapid. For subjects randomised to Novorapid, they will receive supplemental Novorapid if their glucose level is >8 mmol/L at a standard testing time (before meals/after meals/2200), in accordance with an algorithm which takes into consideration the subject's weight, glucose level and time of day. Subjects randomised to Actrapid will be administered supplemental insulin if their glucose level is >10 mmol/L, in accordance with a similar algorithm. The intervention will continue until discharge, or the occurence of an event which mandates withdrawal (eg becomes nil by mouth, insulin infusion commenced). This is a hospital based intervention only.

Outcomes
Primary outcome [1] 4377 0
Frequency of mild (blood glucose 3-4 mmol/L), severe (blood glucose level <3 mmol/L) and all hypoglycaemic episodes during the period of the person's participation in the trial
Timepoint [1] 4377 0
This will be assessed over the entire period of the person's involvement in the trial, and determined on the basis of blood glucose measurements by fingerprick performed at standard times before and after meals, bedtime and 0200-0300.
Primary outcome [2] 4378 0
Frequency of mild (blood glucose level (BGL) >12 mmol/L), severe (blood glucose level >16 mmol/L) and total hyperglycaemia
Timepoint [2] 4378 0
This will be assessed over the entire period of the person's involvement in the trial, and determined on the basis of blood glucose measurements by fingerprick performed at standard times before and after meals, bedtime and 0200-0300.
Primary outcome [3] 4379 0
Mean BGL over the Mandatory testing times
Timepoint [3] 4379 0
This will be assessed over the entire period of the person's involvement in the trial, and determined on the basis of blood glucose measurements by fingerprick performed at standard times before and after meals, bedtime and 0200-0300.
