Obtaining accurate blood glucose levels at the bedside is mandatory to titrate insulin infusions in ICU patients under tight glycemic control. We evaluated concurrently the performance of three point-of-care devices – one blood gas analyzer and two glucometers – in an adult ICU.
Simultaneously, arterial blood glucose was measured with RapidLab 1265, the Accu-chek Aviva, the Nova StatStrip and in the central laboratory as reference using the hexokinase method. The Bland–Altman approach and a modified Kanji approach  were used.
Mean bias (mg/dl)
n > 10% discrepancy
n > 20% discrepancy
The very low biases and the low rate of significant (>20%) discrepancy appear sufficient for safe tight glucose control monitoring in the adult ICU.
