A cluster-randomized trial to estimate the effect of mobile screening and treatment feedback on HbA1c and diabetes-related complications in Tshwane primary health care clinics, South Africa

A comprehensive programme that integrates clinical evaluations, active screening and an individualised patient management plan did not lead to significant improvement in the HbA1c levels. However, screening for glycaemic and lipid control, as well as diabetic complications, improved dramatically with a dedicated team. The lower than expected rate of uptake of the specialists-proposed patient management, with the resulting non-significant change in glycaemic control, needs further investigation.
