Use of Color Range Indicator Technology on Point-of-Care Meters May Ease Self-Management of Blood Glucose.

The study by Grady et al is timely and exciting striving toward better understanding of relevant human factors in the design of their glucose meter displays. Their investigation focused on meaningful device optimization objectives that could be important to improving diabetes self-management. Grady et al are to be complimented for their development of a PC-based computer simulator to further our understanding of how patients interpret their glucose meter readings. What is interesting is that important, and hopefully more appropriate decisions, can be made daily or hourly when a meter is capable of displaying the most relevant information in a manner that will prompt the user toward more favorable glucose management decisions.
