A computer-software program more effectively controlled blood-sugar levels among critically ill patients than nurse-directed care did, according to the first large clinical trial of its kind. The results will be presented at The Endocrine Society’s 94th Annual Meeting in Houston. The computer program, known as LOGIC-Insulin, was designed to assist healthcare providers in closely controlling patients’ blood sugar, or glucose, with the hormone insulin. While insulin treatment is effective, it can be extremely difficult to determine the correct dosage. Excessive amounts of the hormone can cause blood sugar to drop to dangerously low levels, which can cause a serious condition called hypoglycemia. If left untreated, hypoglycemia can result in loss of consciousness, and even death.
