Perioperative Insulin Glargine Dosing Study

Patients in Group 1 will administer 80% of their usual insulin glargine dose.

Group 2 patients will contact their own diabetes care physician and follow those recommendations for the dose

Group 3 patients will take 50%, 80%, or 100% of their usual insulin glargine dose. Which of those three percentages will be determined by the midpoint of the patient's usual self-reported fasting blood sugar (FBS) range and whether the patients is also taking a rapid-acting insulin.
