Effect of Internet Therapeutic Intervention on A1C Levels in Type 2 Diabetes Mellitus (DM) on Combination Oral Therapy

2014-08-27 03:16:14 | BioPortfolio


This project will test the effectiveness of an Internet based glucose monitoring system on the A1C levels of patients with type 2 diabetes. All of the patients are given a meter and test strips to test their blood glucose levels, however, half of them will be required to also upload their meter onto the Internet which can then be viewed by their endocrinologist. The doctor can then send a message back to the patient and comment on the readings. The effect of the ongoing communication will be measured by the changes in the glucose levels (HbA1C) over 3 and 6 months.


Purpose: To determine whether use of an Internet-based glucose monitoring system (ALR Technologies Inc.) improves Hemoglobin A1c (HbA1c) levels in patients with type 2 diabetes mellitus treated with 2 or more oral anti-diabetic medication.

Hypothesis: We propose that the standardized encounters using the Internet will improve the outcome of treatment for patients with type 2 DM.

Justification: An important aspect of diabetes care is the self-monitoring of blood glucose (SMBG) levels in order to assess the effectiveness of treatment and to modify the treatment to achieve the desirable glucose levels. All patients with type 2 DM are recommended to perform SMBG. However, it often requires intervention by health professionals in order to prevent the immediate and serious complications of hyper or hypoglycemia. The frequent SMBG and effective interventions by the health professionals may eventually allow tighter control of blood glucose levels and delay or prevent the complications associated with diabetes.

Objectives: We propose to measure HbA1c levels at the beginning of the study and compare this with HbA1c levels at three and six months after initiating Internet-based blood glucose monitoring system (IBMS).

Research Method: Fifty patients will be randomized equally (a 50/50 chance) to either conventional therapy or the use of the Internet blood glucose monitoring system.

Conventional therapy (Control group) will consist of general care comprising of SMBG 3 or more times per day and visits to the endocrinologist at 3-month intervals with HbA1c, cholesterols, and serum creatinine determinations at 3-month intervals for 6 months.

Those patients randomized to the Internet system (Intervention group) will be required to perform SMBG 3 or more times per day and to upload their metered glucose values online every 2 weeks to be reviewed by the doctor. As well, there will be visits to the endocrinologist every 3 months with HbA1c, cholesterols, and serum creatinine measurements at 3-month intervals for 6 months.

Statistical Analysis: The primary endpoint is the HbA1c level or the change in A1c level. The secondary endpoints include severe hypoglycemia defined as requiring external aid, hospital admissions for any CVD related intervention, and adverse events such as unplanned hospitalizations for any cause that last more than 24 hours. For each group, A1C levels before the start of study will be compared to A1C levels 3 and 6 months after the start of the study. Paired t-tests and random effects models (longitudinal analyses) will examine differences in A1C values before and after the study duration. Unpaired, independent t-tests will be done to examine the difference in A1C values between the two groups before and after the interventions. Planned sample size is 50.

Medical and Biotech [MESH] Definitions

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.

A type of diabetes mellitus that is characterized by severe INSULIN RESISTANCE and LIPODYSTROPHY. The latter may be generalized, partial, acquired, or congenital (LIPODYSTROPHY, CONGENITAL GENERALIZED).

A life-threatening complication of diabetes mellitus, primarily of TYPE 1 DIABETES MELLITUS with severe INSULIN deficiency and extreme HYPERGLYCEMIA. It is characterized by excessive LIPOLYSIS, oxidation of FATTY ACIDS, production of KETONE BODIES, a sweet smell to the breath (KETOSIS;) DEHYDRATION; and depressed consciousness leading to COMA.
