Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
STAR is a system that uses an algorithm and computer model to provide equivalent or tighter control of glucose levels. Target glycemic levels will be chosen by the clinical staff dependent on patient characteristics, the most common target range is 4.4-8.0 mmol/L. The algorithm will determine all insulin doses and enteral nutrition given to achieve that target with safety from hypoglycemia. STAR clinical trials will run until 30 June 2012 and will occur whenever there is an eligible patient in the ICU from whom consent has been obtained.

Comparator / control treatment
Retrospective data (of blood glucose, insulin and nutrition) from SPRINT (the current tight glycaemic control protocol in use in Christchurch hospital). The data was gathered from August 2005-May 2007.

Outcomes
Primary outcome [1] 286041 0
Time in target glycaemic control bands (e.g. 4 to 7 mmol/L)
Timepoint [1] 286041 0
As a percentage of total time on STAR for each patient throughout their time on STAR. Blood glucose (BG) measurements are taken 1-3 hourly.
Primary outcome [2] 286042 0
Numbers of patients who experience hypoglycaemia (BG < 2.2 mmol/L) and numbers or percentage of measurements lower than 4.0 mmol/L.
Timepoint [2] 286042 0
Data taken from each patients time on STAR. Blood glucose (BG) measurements are taken 1-3 hourly.
Secondary outcome [1] 295030 0
Measures of glycaemic variability (standard deviation, variation over time)
Timepoint [1] 295030 0
Blood glucose (BG) measurements are taken 1-3 hourly for each patient.

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients will be in-patients in intensive care and will be identified by investigators according to the entry criteria. The intensive care clinicians will approach the patient or if the patient cannot consent him/herself a family/whanau/representative will be approached. All contact will be made within the Department of Intensive Care.
