    Diabetes: Management and Pharmacotherapy

    The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

    Diabetes Mellitus: Type 2 and Gestational

    Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

    A single text message significantly boosted diabetes screening completion, identifying more cases of dysglycemia. This low-cost, scalable method helps increase screening rates for type 2 diabetes prevention.

    Area of Science:

    • Public Health
    • Preventive Medicine
    • Digital Health

    Background:

    • Over 80% of individuals with prediabetes remain undiagnosed in the US.
    • Early intervention can prevent or delay type 2 diabetes progression.
    • Scalable strategies are needed to increase diabetes screening uptake.

    Purpose of the Study:

    • To evaluate if a single text message can increase completion of HbA1c-based diabetes screening.
    • To assess the effectiveness of text message reminders in routine clinical practice.

    Main Methods:

    • Pragmatic randomized controlled trial within Duke University Health System.
    • Adults aged 35+ meeting ADA screening criteria, without prior diabetes diagnosis, and no recent HbA1c test were randomized.
    • Intervention group received a single text message; control group received usual care.

    Main Results:

    • Text message outreach significantly increased HbA1c test completion by 1.18 over 24 weeks.
    • The strongest effect was observed in the first four weeks (HR 1.48).
    • Cumulative testing increased by 1.31% in the messaged group, identifying one dysglycemia case per 213 messages sent.

    Conclusions:

    • A single automated text message effectively increases diabetes screening completion at low cost.
    • This scalable approach can help close the gap in recommended diabetes screening.
    • The method does not selectively engage higher-risk patients, avoiding selection bias.
