Glycemic control

A transformation in critical care patient management

Early interest in tight glycemic control for intensive care patients began in the mid '90s with publication of data from the Portland Diabetic Project showing that post-operative blood glucose levels had an independent effect on the incidence of deep sternal wound infection. This was followed on by data showing post op blood glucose was a highly significant independently predictive variable for mortality.

In 2001 Greet Van den Berghe's landmark prospective trial demonstrated that controlling patient glucose levels in the ICU within tight normal ranges yielded significant improvements in patient outcomes including a 46 per cent reduction in incidence of sepsis, 41 per cent reduction in renal failure, 50 per cent reduction in blood transfusions, and 34 per cent reduction in mortality. This study launched a new field of medical research with over 100 publications in the past decade including two showing a financial benefit to the hospital in savings of $1,580 to €2,638 per patient.


The paper has revolutionized the clinical practice of intensive care units across the world and has established a new standard in post-surgical care.  The challenge for hospitals is that few ICU's have the resources available to draw blood and perform glucose measurements at the frequency required to safely maintain patients within the target glucose range.
