Glycosylated hemoglobin (HbA1c) testing of persons with diabetes is recommended for effective management of blood glucose levels and reduction of microvascular complications.  This project studied the frequency and outcomes of HbA1c testing for Eastern Ontario residents with diabetes using population-based, administrative health databases.

Over one year, 42% were never tested and less than half of those tested had ideal or optimal blood glucose levels.  Younger individuals were tested less often and had poorer outcomes.

Further research is required to identify how patient or physician factors, service availability, and lack of continuity of primary care contribute to this gap.  In the meantime, educational interventions for patients and providers should be considered, as well as policy initiatives to ensure equitable access to care.
