Clinical Trial Summary

Hyperglycemia is common in critically ill patients and associated with an adverse outcome. Thus, glycaemic control is an important issue in critical care. Despite extensive efforts of the intensive care unit staff difficulties were experienced in achieving efficient and safe glucose control. A fully automated algorithm may help to overcome some of these limitations by excluding intuitive interventions and integrating relevant clinical data in the decision-making process. Space GlucoseControl (TGC system) is a decision support system which helps to achieve safe and reliable blood glucose control in the desired ranges. Information on parenteral and enteral nutrition is automatically integrated into the calculations. The primary objective of the current study is to investigate the performance and usability of the Space TGC system for glucose control in medical ICU patients.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	(arterial) blood glucose values -> percentage of time within predefined glucose target range 80-150 mg/dL		all blood glucose measurements from start of treatment until last glucose measurement under treatment (i.e. stop of intravenous insulin treatment) up to a maximum of 14d	No
Secondary	Hypoglycaemia = 40 mg/dl (2.2mM)		all blood glucose measurements from start of treatment until last glucose measurement under treatment (i.e. stop of intravenous insulin treatment) up to a maximum of 14d	Yes
Secondary	Concomitant medication including insulin infusion rate, parenteral/enteral nutrition		all blood glucose measurements from start of treatment until last glucose measurement under treatment (i.e. stop of intravenous insulin treatment) up to a maximum of 14d	No
Secondary	Usability parameters like convenience of alarming function; workload; blood sampling frequency		all blood glucose measurements from start of treatment until last glucose measurement under treatment (i.e. stop of intravenous insulin treatment) up to a maximum of 14d	No
