MEDCAC Meeting

Glycemic Control


Expand All | Collapse All


Diabetes mellitus is a chronic condition associated with abnormally high levels of glucose in the blood whereas the body does not produce enough insulin or the insulin that is produced is ineffective. The blood sugar level may be monitored by the patient at various frequencies.  The high blood glucose levels can sometimes be controlled with diet and exercise alone but may also require the use of insulin or other medications. The main goal of diabetes management is to control blood glucose levels and thereby to prevent the complications of diabetes. Diabetes when not well controlled is a leading cause of adult blindness, lower-limb amputation and kidney disease. The hemoglobin A1C test is a blood test that measures average blood glucose control over a three-month period that helps to identify longer-term trends in glucose levels and where adjustments in treatment are needed.

The MCAC will be reviewing evidence on:

(1) glycemic control using continuous glucose monitors;

(2) the relationship of outpatient glucose monitoring (type and frequency) to glycemic control and/or clinical outcomes in the various Medicare populations;

(3) the relationship of outpatient glycemic control to the clinical outcomes in the various Medicare populations;

(4) The linearity of the effects of glycemic control; and

(5)  the relationship of increase hypoglycemic risk to glycemic control and/or clinical outcomes.

The clinical outcomes reviewed will include blunting the progression of disease, reversing diabetic complications, and altering morbidity/mortality in the Medicare populations.

The role of variables such as the type of diabetes, the therapeutic regimen employed, the age of hyperglycemic onset, the duration of diabetes, the duration of poor glycemic control, the level of hyperglycemia, and concomitant disease will be discussed.

In addition to evaluating the available data, the committee will identify areas in which the current data are deficient and in which additional research is warranted.

     The Medicare Coverage Advisory Committee met on August 30, 2006, to discuss the evidence, hear presentations and public comment, and make recommendations regarding glycemic control and the use of glucose monitors by which sensors automatically monitor glucose levels and body fluids, and whether and how the frequency of outpatient glucose monitoring is related to glycemic control and clinical outcomes in various Medicare populations.

     The meeting began with a reading of conflict of interest issues and an introduction of the Committee.

CMS Summary, Presentation of Voting Questions, and Clinical Background. CMS representatives presented the panel with the questions to be considered by the panel, and also presented and overview of he clinical history and CMS coverage regarding glycemic control and glucose monitoring.

Presentation by Durable Medical Equipment Regional Contractor (DMERC). A presentation was offered by a representative of DMERC.

Presentation of the Technology Assessment. The results of a technology assessment performed by the Tufts New England Medical Center Evidence-Based Practice Center were presented.

Other Presentations. The panel heard presentations from seven additional speakers, including researchers and clinicians. After each presentation, the panel was given an opportunity to ask clarifying questions of the presenters.

Scheduled Public Comments. Twelve speakers, including representatives of professional societies, manufacturers' representatives, and practicing clinicians, addressed the panel.

Open Panel Deliberations. There was an extensive period where the panel discussed each question to be considered, during which several additional questions were posed to the presenters and other speakers.

Discussion and Voting. The panel voted on Questions 1 through 7, with the results being recorded on individual tally sheets and compiled by staff. During the voting procedure, further discussion was held among the panelists concerning each question voted upon.

Further Discussion. Following the voting, each panelist was afforded an opportunity to make comments concerning information they felt would be helpful to CMS addressing coverage issues in this area.

Adjournment. The meeting adjourned at 3:09 p.m.
