Feasibility of Using a Smart Phone Application for Self-titration of Insulin on Glycemic Control in Patients With T2DM

The primary aim of this study is to investigate the feasibility of using a patient-centered smart phone application for insulin self-titration on glycemic control. Over a 18-month period, suboptimally controlled type 2 diabetes mellitus (T2DM) on oral antidiabetic agents, thus requiring insulin treatment patients, will be recruited from the Singapore General Hospital (SGH). Patients randomized to the intervention group will be instructed to self-adjust their insulin dose using a smart phone application designed to guide self-titration; patients randomized to the control group will receive the usual clinical care. The primary outcome measure is change in glycated hemoglobin level (HbA1c), 6 months post-enrollment. The investigators hypothesize that using a smart phone application for insulin self-titration is effective in improving glycemic control in T2DM patients compared with usual care.
