Purpose: To compare capillary point-of-care glucose testing (POC) and a central venous catheter sample POC to the gold standard of venous laboratory measurement. Background/Significance: Critical care nursing practice requires hourly glucose testing to titrate insulin infusions that maintain glucose levels within the desired range. While using blood obtained from a fingerstick sample is usually done, ICU nurses often use blood drawn from a central venous catheter to perform the test. It is not clear which POC sample best correlates with the true blood glucose as measured in the lab. Methods: A method-comparison study design was used to examine the...
