Telemedicine had no convincing effect on quality of life , mortality or hypoglycemia .
INTERPRETATION : Compared with usual care , the addition of telemedicine , especially systems that allowed medication adjustments with or without text messaging or a Web portal , improved HbA1C but not other clinical ly relevant outcomes among patients with diabetes
BACKGROUND : Telemedicine , the use of telecommunications to deliver health services , expertise and information , is a promising but unproven tool for improving the quality of  diabetes care  .
We summarized the effectiveness of different methods of telemedicine for the management of diabetes compared with usual care .
The Cholesterol, Hypertension, And Glucose Education (CHANGE) study: results from a randomized controlled trial in African Americans with diabetes.
BACKGROUND Cardiovascular disease ( CVD ) and diabetes account for one-third of the mortality difference between African American and white patients . We evaluated the effect of a CVD risk reduction intervention in African Americans with diabetes . METHODS We r and omized 359 African Americans with type 2 diabetes to receive usual care or a nurse telephone intervention .  The 12-month intervention provided monthly self-management support and quarterly medication management facilitation . Co primary outcomes were changes in systolic blood pressure ( SBP ) , hemoglobin A1c ( HbA1c ) , and low-density lipoprotein cholesterol ( LDL-C ) over 12 months . We estimated between-intervention group differences over time using linear mixed-effects models . The secondary outcome was self-reported medication adherence . RESULTS The sample was 72 % female ; 49 % had low health literacy , and 37 % had annual income < $ 10,000 . Model-based estimates for mean baseline SBP , HbA1c , and LDL-C were 136.8 mm Hg ( 95 % CI 135.0 - 138.6 ) , 8.0 % ( 95 % CI 7.8 - 8.2 ) , and 99.1 mg/dL ( 95 % CI 94.7 - 103.5 ) , respectively . Intervention patients received 9.9 ( SD 3.0 ) intervention calls on average . Primary providers replied to 76 % of nurse medication management facilitation contacts , 18 % of these result ed in medication changes . There were no between-group differences over time for SBP ( P = .11 ) , HbA1c ( P = .66 ) , or LDL-C ( P = .79 ) . Intervention patients were more likely than those receiving usual care to report improved medication adherence ( odds ratio 4.4 , 95 % CI 1.8 - 10.6 , P = .0008 ) , but adherent patients did not exhibit relative improvement in primary outcomes . CONCLUSIONS This intervention improved self-reported medication adherence but not CVD risk factor control among African Americans with diabetes . Further research is needed to determine how to maximally impact CVD risk factors in African American patients
