Disease management assessment involves several steps: diagnosis, short and long term studies. From the hospital educational experience conducted in Vichy, hospital and office based practitioners developed a coordinated and multidisciplinary therapeutic educational approach, the “Vichy Diabète healthcare network”. Two assessment steps have been conducted. OBJECTIVES: Initial objective was to analyse the “hospital therapeutic education program” on diabetic patients knowledge and to identify ways for improvement. The objective of the second step was to validate, after a few months, the choices made by the network. METHODS: Qualitative and quantitative studies were based on data currently collected, questionnaires submitted to diabetic patients who followed the hospital program and practitioners who belong to the network. RESULTS: Initial assessment showed that the hospital program impact alone is modest. A total of 67% of the patients considered that diabetes is a severe disease; 68% estimated that they do their best to treat themselves; 60% declared that the treatment is difficult in every day life, 50% hadn’t changed their behaviour since the diabetes diagnostic; 21% didn’t know the potential complications. This underlined the need to develop the “Vichy Diabète network”. The second step confirmed these observations; 87.9% of interviewed practitioners estimated that patients could improve their behaviour. According to them, respectively 57.5% and 66.7% didn’t know well the targeted glycaemia and HbA1C definition, 42.4% thought that diabetes isn’t a severe disease. Adherence to diet and physical activity recommendations is considered very insufficient. Thus, according to patients and practitioners, the “Vichy Diabète network” answered to their needs and expectations. CONCLUSIONS: Assessment approach conducted at different steps is particularly adapted to networks project. It brings a lot of information to network care givers on strategic choices and impact on health organisation.
