Glycated haemoglobin (HbA1c) is the best surrogate of average blood glucose control in diabetic patients. Large-scale studies in the USA and UK have demonstrated that lowering HbA1c significantly reduces diabetes complications. Moreover, immediate feedback of HbA1c measurement to patients improves control. However, HbA1c is unavailable in most parts of Africa, a continent with one of the highest burden of diabetes. To translate these evidences, the investigators will provide affordable access to HbA1c measurement and relevant education in 2 African countries aiming significant improvement of diabetes control. The investigators will develop with local health authorities, training and cost-recovery scheme for long-term sustainability.

Condition Intervention
Diabetes Mellitus

    Baseline to 12 months individual change in HbA1c level

Secondary Outcome Measures:
  • One-year change in proportion of patients reaching HbA1c targets [ Time Frame: Baseline and 12 months ]
    Baseline to 12 months change in proportion of patients reaching HbA1c targets in each participating centre and in the overall population

  • One-year change in urinary albumin excretion [ Time Frame: Baseline and 12 months ]
    Baseline to 12 months individual change in early morning sample urinary albumin excretion
