Diabetes consultation versus diabetes education in patients with poor glycaemic control: A telemedicine intervention study

Abstract

Introduction The prevalence of diabetes is increasing around the world, especially in populations with limited health service resources. Diabetes is associated with increased mortality and cost. Therefore, we investigated the impact of increasing access to diabetes care through telemedicine. Methods Five rural communities were connected via videoconference. Patients received diabetes consultation (DC) or diabetes self-management education (DSME). DC was performed by an endocrinologist, while DSME was delivered by a certified diabetes educator. Haemoglobin A1c (HbA1c), blood pressure (BP) and lipid profile were evaluated as outcome measures. Results Sixty-nine subjects (70% females, 91% Caucasians) were studied, with 33 receiving DC and 36 receiving DSME. Patients were aged 56.7 ± 9.4 and 56.5 ± 6.7 years, respectively ( p > 0.5), and had had diabetes for 11.4 ± 10.1 and 11.7 ± 9.2 years, respectively ( p > 0.5). Both DC and DSME reduced HbA1c equally: DC at baseline 9.3 ± 1.3% compared to at 12 months 7.2 ± 0.9% ( p = 0.0002), and DSME at baseline 9.8 ± 1.6% compared to at 12 months 8.3 ± 1.9% ( p = 0.009). There was no difference in HbA1c between DC and DSME at baseline and at 12 months ( p > 0.1). On the average, BP and lipids were equally controlled in DC and DSME at six months: total cholesterol 178.3 ± 50.5 mg/dL versus 185.9 ± 57.3 mg/dL, low-density lipoprotein cholesterol 91.4 ± 36.1 mg/dL versus 91.5 ± 50.2 mg/dL, high-density lipoprotein cholesterol 46.2 ± 11.0 mg/dL versus 43.5 ± 10.8 mg/dL, systolic BP 136.8 ± 23.6 mmHg versus 131.9 ± 22.3 mmHg, diastolic BP 72.0 ± 13.2 mmHg versus 77.7 ± 11.3 mmHg ( p > 0.1). All subjects found DC and DSME cost effective, while 97% reported better diabetes control. Discussion In patients with long-standing uncontrolled diabetes who lived in rural communities with high diabetes-related mortality rates, DC or DSME delivered by videoconference improved glycemic control. No difference was found between the two interventions.

Impact of telehealth on the current and future practice of lipidology: a scoping review

“… Majithia et al 17 2020 Pre-post 55 DM 4 months Video consult, mobile application, remote consult, connected BGMs and CGMs HbA1c, blood glucose levels, BP, TC, HDL-C, TC/HDL ratio, LDL-C, TG Significant improvements in LDL-C, TC/HDL ratio, TG, HbA1c, BMI, and SBP in telehealth group. Nyenwe et al 59 2020 Pre-post 69 DM 36 months Video consult HbA1c, BP, lipid profile No significant difference in lipid levels between groups. Telehealth group improved glycemic control.…”

A new nomogram model for the individualized prediction of mild cognitive impairment in elderly patients with type 2 diabetes mellitus

“…In an Advanced Chronic Kidney Disease Study, interventions to lower HbA1c levels did not affect cognitive decline ( 41 ). However, a Diabetes Education and Telemedicine Study (IDEATel) demonstrated that cognitive decline was observed with interventions at HbA1c <7.0% ( 42 ). In this study, the higher the HbA1c level, the more likely the patient was to develop MCI, indicating a bidirectional relationship between cognitive impairment and diabetes management.…”

Usability and Teachability of Continuous Glucose Monitoring Devices in Older Adults and Diabetes Educators: Task Analysis and Ease-of-Use Survey

“…They often work as part of a care team to help those with diabetes understand their disease and achieve their goals in managing diabetes. A recent study found that glycemic and metabolic outcomes were similar in patients who received a telehealth-based diabetes consultation with an endocrinologist or a diabetes self-management education visit with a CDCES [5]. Because CDCESs train patients who are new to CGM, their comfort with CGM device insertion and app setup is also critical to patient training and adoption.…”
