The national health service England diabetes prevention program—A narrative review

Abstract

Abstract The National Health Service (NHS) Diabetes Prevention Program (DPP) is a comprehensive initiative in the United Kingdom aimed at preventing type 2 diabetes (T2DM) among individuals with prediabetes. The NHS DPP emphasizes early intervention and underscores the potential for preventing or delaying T2DM. Currently, it operates since 2015 at 44 geographically defined sites, serving an estimated annual volume of 200,000 patients. This narrative review evaluates the NHS DPP. A literature search, adhering to the Participants, Concept, and Context review framework, was conducted in various databases and sources, limited to the period from 2015 to 2023. Data were categorized based on publication date, study type, program indicators, and focus areas, forming the framework for the review discussion. The review search yielded a total of 18,357 articles, of which 45 were included, with a predominant focus on program effectiveness. The NHS DPP demonstrates strengths in risk reduction and cost-effectiveness but faces challenges related to fidelity and the needs of diverse populations. The review highlights the importance of evidence-based service delivery, stakeholder engagement, and digital innovation in future DPP programs. While a centralized approach provides structure, local flexibility is essential to cater to population-specific needs. This review underscores the importance of strategic planning, political support, partnerships, and robust data collection in DPP implementation. It recommends targeting high-risk individuals, intensive lifestyle interventions, and embracing digital solutions for program delivery. Ongoing research, including analysis of long-term data and user perspectives, will further enhance the evidence base for DPP programs worldwide.
