Summary
Digital Diabetes Prevention Program (DPP) implementation in a healthcare system showed favorable cost-effectiveness. The digital intervention led to lower overall costs and significant weight loss, particularly for high-risk individuals, making it a valuable public health strategy.
Area of Science:
- Health Economics
- Preventive Medicine
- Digital Health
Background:
- The Diabetes Prevention Program (DPP) is a proven intervention for preventing type 2 diabetes.
- Digital adaptations of the DPP are emerging as scalable solutions within healthcare systems.
Purpose of the Study:
- To conduct an economic evaluation of a digital DPP implemented in a large, integrated healthcare system.
- To determine the cost-effectiveness of the digital DPP, focusing on weight loss outcomes.
Main Methods:
- A propensity score-matched analysis compared patients enrolled in the digital DPP with those not enrolled.
- Data from electronic medical records identified 4148 eligible patients, with 784 matched for analysis.
- Cost and medical care costs were tracked over 12 and 24 months, with incremental cost-effectiveness ratio (ICER) calculated per kilogram of weight loss.
Main Results:
- Enrolled patients demonstrated lower total costs at 12 months ($6,926 vs. $7,538) and 24 months ($16,255 vs. $16,688).
- The digital DPP achieved an ICER of $81.92 per kilogram of weight loss.
- High-risk patients in the digital DPP group experienced lower costs and greater weight loss, with a 60% probability of cost-effectiveness at a willingness-to-pay of $150/kg.
Conclusions:
- The digital DPP exhibits a favorable cost-effectiveness profile compared to traditional lifestyle interventions.
- This digital approach offers a scalable and economically viable strategy for diabetes prevention within integrated healthcare settings.
- The intervention is particularly effective for high-risk populations, suggesting targeted implementation could maximize benefits.

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.

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

2.7K
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...

An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...
