Information and Communication Technology Based Centralized Clinical Trial Monitoring System for Insulin Dose Adjustment (ICT)
An Information and Communication Technology-based Centralized Clinical Trial to Determine the Efficacy and Safety of Insulin Dose Adjustment Education Based on a Smartphone Personal Health Record Application
This is a 24-week, open-label, randomized, multi-center trial conducted in three tertiary hospitals. There are three follow-up measures; at baseline, post-intervention at Week 12, and Week 24. Subjects are diagnosed as type 1 DM, type 2 DM, and/or post-transplant DM, and initiate or currently use insulin therapy. After the given education on insulin dose titration and prevention for hypoglycemia and 1 week of run-in period, subjects are randomized in a 1:1 ratio to either the ICT-based intervention group or the conventional intervention group. Subjects in conventional intervention group will save and send their health information to the server via the PHR app, whereas those in ICT-based intervention group have additional algorithm-based feedback messages. The health information includes levels of blood glucose, insulin dose, details on hypoglycemia, food diary, and number of steps. The primary outcome will be the proportion of patients who reach an optimal insulin dose within 12 weeks of enrolling in the study without severe hypoglycemia or unscheduled clinic visits.
This study is based upon work supported by the Ministry of Trade, Industry & Energy (MOTIE, Korea) under Industrial Technology Innovation Program (No. 10059066, 'Establishment of ICT Clinical Trial System and Foundation for Industrialization.")

Reaching optimal insulin dose: A.For a patient who uses basal insulin only or basal insulin with pre-meal rapid-acting insulin once per day,1)3 or more fasting blood glucose(FBG) values in the morning within the target range(80-130mg/dL or 100-140 mg/dL) during Week12,2)no nocturnal(11pm-7am) or pre-breakfast hypoglycemia(<70mg/dL) during Week12,3)variation of basal insulin dose (the difference between the highest and lowest basal insulin dose) of <10% of mean total basal insulin dose during Week12.
B.For a patient who uses MDI at least twice per day, the criteria A plus 4)3 or more days in which correction dose premeal insulin is required less than 3times per day during the Week12,5) no daytime(7am-11pm) hypoglycemia during Week12.
C.For a patient who uses premixed insulin or NPH,1)3 or more FBG values in the morning and evening within the target range during Week 12,2) no nocturnal or pre-breakfast hypoglycemia during Week12
