About this study
Background: Diabetes is a common, morbid and expensive disease among veterans. Achieving adequate glycemic control and blood pressure control can reduce the devastating complications of diabetes. Because the majority of patients do not achieve adequate control of blood sugar and blood pressure, innovative strategies to improve control are needed. One strategy with great potential for veterans receiving VA care is the group clinic. Group clinics have been developed over the last 5-10 years, and have been shown to improve clinical outcomes and reduce outpatient utilization in geriatric settings. Group medical clinics involve a cohort of 8-20 patients who have 1-2 hour group visits. These clinics are distinguished from traditional group education visits for diabetes by the fact that these visits involve one physician and one or more additional health care professionals, usually a nurse practitioner and/or a pharmacist, and are designed to make management changes for a number of people with the same disease in a short period of time. The effect of group medical clinics on blood sugar, blood pressure, and the cost of diabetes care, is unknown. Objectives: Our primary objectives in this project are to determine the effectiveness and cost-effectiveness of a group visit intervention in improving rates of control of diabetes and high blood pressure in patients with both illnesses.

Background:
Diabetes is a common, morbid and expensive disease among veterans. Achieving adequate glycemic control and blood pressure control can reduce the devastating complications of diabetes. Because the majority of patients do not achieve adequate control of blood sugar and blood pressure, innovative strategies to improve control are needed. One strategy with great potential for veterans receiving VA care is the group clinic. Group clinics have been developed over the last 5-10 years, and have been shown to improve clinical outcomes and reduce outpatient utilization in geriatric settings. Group medical clinics involve a cohort of 8-20 patients who have 1-2 hour group visits. These clinics are distinguished from traditional group education visits for diabetes by the fact that these visits involve one physician and one or more additional health care professionals, usually a nurse practitioner and/or a pharmacist, and are designed to make management changes for a number of people with the same disease in a short period of time. The effect of group medical clinics on blood sugar, blood pressure, and the cost of diabetes care, is unknown.
Objectives:
Our primary objectives in this project were to determine the effectiveness and cost-effectiveness of a group visit intervention in improving rates of control of diabetes and high blood pressure in patients with both illnesses.
Methods:
We performed a two-site, randomized, controlled trial of group medical visits for diabetes management. Patients were patients in primary care at the Durham or Richmond VAMC's who had inadequate control of both their blood sugar and their blood pressure. We excluded patients with life-limiting illness. Patients randomized to the control arm received usual primary care. Patients randomized to the intervention arm were assigned to attend a group medical clinic every two months for one year. In the clinic, a primary care physician, with the assistance of a nurse and a pharmacist, measured blood pressure at the point of care, reviewed blood sugar logs, and then made all necessary medical changes for patients with diabetes. The primary outcomes were hemoglobin A1c and systolic blood pressure. Additional outcomes will be serum LDL-cholesterol, diabetes-specific quality of life, and health services utilization. Formative evaluation was undertaken to determine the mechanism of the intervention and to prepare for more successful dissemination if the intervention is effective. Formal cost analysis will be performed and cost-effectiveness analysis will be undertaken. All outcomes were measured at baseline, and 6 and 12 months after the beginning of the intervention.
Status:
All patient contact complete. Project is in analysis phase.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Diabetes Group Management Visits in people with Diabetes and Hypertension, run by US Department of Veterans Affairs at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 11 Sep 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hemoglobin A1c (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00286741, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jan 2019.
