Background, objectivesThe diabetes care network ‘Maison du diabète et de la nutrition de Nancy et 54’ (MDN54) is a territorial structure which organises formalised and structured therapeutic patient education (TPE) by a multidisciplinary team for type 2 diabetic patients (T2DM) or obese people, usually not treated by an endocrinologist. The goal of this study was to (1) compare baseline characteristics of the T2DM patients from MDN54 with patients followed in a diabetes university hospital department (CHU), (2) to describe the follow up of those patients during 1 year and (3) to compare the changes of some relevant parameters between the territorial and the hospital structure.Programme: description, implementation, monitoring elementsT2DM patients are registered at MDN54 by their general practitioner. The patients take part to TPE programs according to a formalised programme as recommended by the HAS: educational diagnosis, group sessions and/or individual face-to-face meeting with an educator, assessment of self-management, and more educational sessions if needed. The sessions are conducted by a multidisciplinary team including private nurses, dieticians, physiotherapists, psychologists and chiropodist. All the sessions take place outside the hospital, at the head office of the MDN54 or in other quarters or cities (rooms offered by local authorities). The family physician is responsible for the annual diabetes check up according to the french national guidelines. TPE programmes have been adapted to primary care during training courses for general practitioners organised by the CHU team. This annual monitoring includes relevant clinical characteristics (body mass index, blood pressure, diabetes complications: retinopathy, neuropathy, wound risk level for diabetic feet, …) and biological results (HbA1c, LDL-cholesterol, HDL-cholesterol, triglycerides, creatinine's clearance by MDRD, microproteinuria, etc). The MDN54’s cohort included 486 T2DM patients registered between 2005 and 2008; 243 patients had had a complete initial annual assessment and 100 patients 2 successive annual assessments. CHU's cohort included 1997 patients and among them 848 T2DP with 2 successive annual assessments on the same period. Seventy-five patients of both populations were matched (CHUap and MDN54ap) using the propensity score on the initial values of several parameters (age, sex, duration of diabetes, BMI, total cholesterol, creatinine's clearance, retinopathy, renal failure, neuropathy, wound risk, hypertension, peripheral vascular disease, treatment with insulin).Results in terms of clinical impactInitial age (62.8 vs 63.0 years), BMI (31.7 vs 31.3 kg/m2) and HbA1c (7.53 vs 7.49%) of the two cohorts (MDN54 vs CHU) were similar (p=NS). Diabetes' duration (14.3 vs 9.0 years), rate of retinopathy (28.3 vs 10.4%) and nephropathy (44.9 vs 22.2%) were higher in the CHUs cohort (p<0.001). There was an improvement in HbA1c level for MDN54 patients at 1 year (7.53 vs 7.22%, p<0.001). The 1 year changes in HbA1c were similar in the two matched...
