Intensified Treatment and Education of Type 1 Diabetes As Clinical Routine. A Nationwide Quality-circle Experience in Germany. ASD (the Working Group on Structured Diabetes Therapy of the German Diabetes Association)

This contribution describes the nationwide implementation of an intensive treatment and education program for type 1 diabetic patients in the clinical routine of the German health care system. Based on the formation of a working group (Arbeitsgemeinschaft Strukturierte Diabetestherapie [ASD]) of presently 57 general internal medicine departments, mainly from secondary and tertiary care levels in city and country hospitals throughout the country, a peer-review quality circle was formed as an official working group of the German Diabetes Association. The participating institutions performed a structured program of intensive treatment and education in all type 1 diabetic patients referred to them on a routine basis. The program includes multiple daily insulin injections or continuous subcutaneous insulin infusion, several times daily blood glucose self-monitoring and self-adaptation of insulin dosages and other aspects of treatment by the patients, and a far-reaching liberalization of the nutrition regimen. The group has attempted to document and to improve the quality of the structure and process of type 1 diabetes care in its participating institutions by a system of peer supervision. Furthermore, all member institutions volunteered to collect outcome data based on systematic 1-1.3 years' follow-up examinations of consecutive type 1 diabetic patients. For the 1997 evaluation of 1,103 type 1 diabetic patients, significant decreases of GHb levels and of incidence rates of severe hypoglycemia (from 0.35 to 0.16 cases per patient-year) and ketoacidosis (from 0.08 to 0.02 cases per patient-year) are presented. The ASD quality circle represents a model to improve principal aspects of type 1 diabetes care on a nationwide basis.
