Interventions

  • Standard IDPP — BEHAVIORAL
    Participants in the control group will receive the standard IDPP as routinely delivered by the DHCs, without additional engagement or implementation strategies. This includes up to four optional group education sessions, two annual nurse-led consultations, and up to three individual counselling sessions per year.
  • Optimized IDPP — BEHAVIORAL
    The optimized IDPP maintains the one-year IDPP structure while adding pre-implementation staff training, two enhanced nurse consultations, a structured reminder and follow-up system, and sustainment strategies.

Study Details

The goal of this clinical trial is to explore the effectiveness and implementation outcomes of the optimized Intensive Diabetes Prevention Program (IDPP) in District Health Centres. The main questions it aims to answer are: * Do the implementation strategies - patient engagement system, structured training, and reminder systems - work better than usual approaches in terms of acceptability, adoption, appropriateness, feasibility, sustainability, and implementation cost? * Do patient health outcomes - HbA1c levels, BMI, lipid profile, quality of life, perception of empowerment, and health service utilization - stay the same or get better when these improved strategies are used compared to usual approaches?

Arms

  • Active Comparator: Control group
    Participants in the control group will receive the standard IDPP as routinely delivered by the DHCs, without additional engagement or implementation strategies. This includes up to four optional group education sessions, two annual nurse-led consultations, and up to three individual counselling sessions per year.
  • Experimental: Intervention group
    The intervention group will follow the same one-year IDPP structure as the control group, but will experience a series of optimized implementation strategies including adding pre-implementation staff training, two enhanced nurse consultations, a structured reminder and follow-up system, and sustainment strategies.
