简要总结
140 subjects will be enrolled into the clinical study and randomized into the Control Group or the Experimental Group by block randomization. The subjects must meet all inclusion and none of the exclusion criteria. Each subject will have 7 clinic visits and 3 phone visits. The Baseline Visit will consist of a complete history, vitals, a physical examination and completion of the consent and screening process. All clinic visits, except for the Baseline Visit will include meter/PDA download. In addition, meter education will be provided to all subjects, and PDA education will be provided to the Experimental group at the Baseline Visit and 2-Week Visit as needed to ensure subject understanding. The phone visits will consist of a history including any changes in insulin dose, and any hypoglycemic events, hyperglycemic events, or other adverse events that have occurred since the last clinic visit.
The primary endpoint in this study was to show a reduction in A1c of at least 0.4% or higher in the insulin guidance software group at 6 months and/or 1 year.
详细描述
Research Design and Methods A total of 123 adult subjects with type 1 diabetes with a baseline A1c of 7.5-11% were enrolled in the study at the Barbara Davis Center for Childhood Diabetes at the University of Colorado at Denver Health Sciences Center. Two patients screen failed (entry criteria not met) before randomization, leaving 60 subjects randomized to the control group and 61 subjects randomized to the experimental group (Advisor). Subjects were randomized based on lottery system using sealed envelopes. All patients had baseline blood work which included a complete blood count (CBC), complete metabolic panel (CMP), creatnine kinase (CK) and an A1c. The mean A1c at baseline was 8.54 ±0.11 in the control group and 8.42 ±0.11 in the experimental group (p=0.4265).
Subjects were randomized on a 1:1 basis to either the experimental or control group. All subjects in the experimental group received the same training for insulin guidance software program for personal data assistant (PDA). All subjects were given a glucose meter and an unlimited supply of test strips for self monitoring of blood glucose (SMBG). Women who were pregnant or planning to become pregnant were excluded from participation in the study as were patients on insulin pumps, those taking glucocorticoid therapy, and those diagnosed with cancer, liver disease, anemia or hepatitis. Patients who exercised more than five days a week, or often traveled internationally were also excluded.
The protocol was approved by the Colorado Multiple Institutional Review Board (COMIRB). All subjects signed an informed consent form before being enrolled in the study.
Visits All subjects were asked to attend 7 in clinic visits (baseline, 2 week, 6 week, 3 month, 6 month, 9 month and 12 month) and participate in 3 telephone visits (4.5month, 7.5month, 9.5 month) throughout the course of the study. Data for blood glucose values, testing frequency, hyperglycemic excursions, hypoglycemic events (all, nocturnal, and severe), insulin dose, weight and BMI, hospitalizations, emergency room visits and illnesses were recorded at each in clinic visit. All subjects completed a patient satisfaction questionnaire and the experimental group also completed an Advisor questionnaire.
As part of their routine clinical care, any additional phone visits were equally encouraged in both groups.
