Diabetes mellitus

Diabetes mellitus is a medical disorder characterized by varying or persistent hyperglycemia (elevated blood sugar levels), especially after eating. All types of diabetes mellitus share similar symptoms and complications at advanced stages. Hyperglycemia itself can lead to dehydration and ketoacidosis. Longer-term complications include cardiovascular disease (doubled risk), chronic renal failure (it is the main cause for dialysis), retinal damage which can lead to blindness, nerve damage which can lead to erectile dysfunction (impotence), gangrene with risk of amputation of toes, feet, and even legs. The more serious complications are all more common in those with poor glycemic control.

Public health, policy and health economics

The Declaration of St Vincent was the result of international efforts to improve the care accorded to diabetics. Doing so is important if only economically. Diabetes is enormously expensive for healthcare systems and governments. In North America, it is the largest single non-traumatic cause in adults of amputation, blindness, and dialysis, all extremely expensive events.

Work in the Puget Sound area of North America (by the health organization Group Health) shows that, over its large and varied patient population, specially retaining medical information on diabetic patients, keeping it up to date, and basing their continuing care on that data reduced total healthcare costs for those patients by US$1000 per year per patient for the rest of life. Recognition of this reality drove the Hawkes Bay initiative which established such a system, and resulted in various activities throughout the world including the Black Sea Telediab project which produced elements of a distributed diabetic record and management system as an open source computer program.
