Scientific titlePilot Effectiveness of Randomised Mandatory Insulin Therapy (PERMIT)
Study acronymPERMIT
Study objectivesCurrent information as of 23/07/2009:
In patients requiring more than 48 hours of critical care treatment, mandatory insulin therapy, in comparison to usual sliding scale insulin therapy will not alter glycaemic control (including the number of severe hypoglycaemic events), but will modulate the derangements in the somatotrophic axis seen in critically ill patients.

Initial information at time of registration:
In patients requiring 5 or more days of critical care treatment, giving mandatory insulin therapy, compared to usual sliding scale insulin therapy as required, the number of severe hypoglycaemic events will be unchanged.
Ethics approval(s)Oxford Research Ethics Committee (REC) C, ref: 05/Q1606/103

Primary outcome measureCurrent information as of 23/07/2009:
1. Glycaemic control (measured as proportion of hyperglycaemic time, number of severe hypoglycaemic episodes per patient)
2. Effects on the somatotrophic axis

Initial information at time of registration:
Number of episodes of hypoglycaemia per unit length of stay in the ICU
Secondary outcome measuresCurrent information as of 23/07/2009:
1. Biochemical markers:
1.1. The number of patients undergoing a hypoglycaemic episode and the number of hypoglycaemic episodes whilst receiving the study protocol
1.2. The number of patients undergoing a hypokalaemic episode and the number of hypokalaemic episodes whilst receiving the study protocol
1.3. Plasma concentrations of IGF-1, IGF-2, IGFBP-1, IGFBP-3, GH at baseline and on days 3,5, 8 and 15 of ICU stay
1.4. Plasma concentrations of HDL, LDL, TG's, FFA's at baseline and at days 3, 5 and 8 and 15 of ICU stay
1.5. The difference between nitrogen excretion (as urinary urea) and nitrogen intake (as enteral or parenteral nutrition) on days 3, 5 and 8 of ICU stay
1.6. Plasma protein carbonyl quantification on days 1, 3, 5, 8 and 15 of ICU stay

2. Morbidity and mortality:
2.1. ICU length of stay
2.2. Antibiotic free days
2.3. 30 day mortality

3. Markers of protocol compliance:
3.1. Time-weighted average blood glucose concentration
3.2. Time-weighted average serum potassium concentration
3.3. Time-weighted average insulin infusion and total insulin delivered

Initial information at time of registration:
1. Biochemical markers:
1.1. The number of episodes of hypokalaemia per unit length of stay in the ICU
1.2. The plasma levels of IGF-1, IGFBP-1, IGFBP-3, ALS on days 1, 3, 5, 8 and 15 of ICU stay
1.3. The plasma HDL, LDL and triglycerides on days 1, 3, 5, 8 and 15 of ICU stay
1.4. The plasma levels of free fatty acids on days 1, 3, 5, 8 and 15 of ICU stay
1.5. The difference between nitrogen excretion (as urinary urea) and nitrogen intake (as enteral or parenteral nutrition) on days 1, 3, 5, 8 and 15 of ICU stay
1.6. Plasma protein carbonyl quantification on days 1, 3, 5, 8 and 15 of ICU stay

2. Surrogate markers for improved long term outcome:
2.1. ICU length of stay
2.2. Hospital length of stay
2.3. Antibiotic free days (as a measure of nosocomial infection)

3. Mortality:
3.1. ICU mortality
3.2. 30 day mortality
3.3. Hospital mortality

4. Markers of protocol compliance:
4.1. Time-weighted average blood glucose concentration
4.2. Time-weighted average serum potassium concentration
4.3. Time-weighted average insulin infusion and total insulin delivered
