The current practice of insulin titration for diabetics requires multiple in-person clinic visits, during which a patient's long-acting insulin dose is adjusted until the optimal dose to control glycemia is reached. Finding this optimal dose can take weeks in an ideal setting, but often takes much longer in a busy urban clinic such as Bellevue Hospital Center. Relaying titration instructions to patients via phone and text message has the potential to decrease the titration timeline, thus reducing the number of clinic visits and the time it takes patients to reach their target blood glucose levels.
