Costs and management of patients with hemophilia A in France: the Hemraude study.

OBJECTIVE: The Hemraude study was conducted to describe the profile of patients with HA, disease management, and economic burden in a collective perspective. METHODS: This retrospective study was conducted using the French administrative healthcare claims database SNIIRAM/SNDS. Male patients treated for hemophilia A with a long-term illness (ALD) status or invalidity were included in the study between January 1, 2016 and December 31, 2017. Patients were classified in six treatment groups: no treatment, on-demand FVIII, prophylactic FVIII, FVIII in immune tolerance induction (ITI) protocol, on-demand bypassing agents, and prophylactic bypassing agents. Patients treated with FVIII in ITI protocol and those treated with bypassing agents are deemed to have developed inhibitors. HA patients were compared to a control population without coagulation disorder and matched (ratio 1:3) on age and sex. RESULTS: A total of 4172 patients were included in the analysis, aged on average 35.2 years, 5.3% had HIV infection, and 8.8% had hepatitis B or C. In 2017, half of the patients received no treatment for HA, 46.7% were treated with FVIII (25% on demand, 20.6% with prophylaxis, and 1.1% ITI), 1.5% with bypassing agents. Patients treated with prophylactic treatments, either inhibitor or non-inhibitor, were less likely to be hospitalized for severe bleeding compared to patients receiving on-demand treatments. The average annual costs for HA management per patient were 72,209.60 €. The highest costs were observed in patients treated with FVIII in ITI protocol and those receiving prophylactic bypassing agents. CONCLUSION: Direct costs of HA treatments for HA may be very high especially in the small percentage of patients developing inhibitors or treated with ITI protocol.

Design of a prospective, longitudinal cohort of people living with type 1 diabetes exploring factors associated with the residual cardiovascular risk and other diabetes-related complications: The SFDT1 study.

Type 1 diabetes mellitus (T1DM) is associated with a high risk of cardiovascular (CV) complications, even after controlling for traditional CV risk factors. Therefore, determinants of the residual increased CV morbidity and mortality remain to be discovered. This prospective cohort of people living with T1DM in France (SFDT1) will include adults and children aged over six years living with T1DM, recruited throughout metropolitan France and overseas French departments and territories. The primary objective is to better understand the parameters associated with CV complications in T1DM. Clinical data and biobank samples will be collected during routine visits every three years. Data from connected tools, including continuous glucose monitoring, will be available during the 10-year active follow-up. Patient-reported outcomes, psychological and socioeconomic information will also be collected either at visits or through web questionnaires accessible via the internet. Additionally, access to the national health data system (Health Data Hub) will provide information on healthcare and a passive 20-year medico-administrative follow-up. Using Health Data Hub, SFDT1 participants will be compared to non-diabetic individuals matched on age, gender, and residency area. The cohort is sponsored by the French-speaking Foundation for Diabetes Research (FFRD) and aims to include 15,000 participants.

Flu vaccine coverage for recommended populations in France.

OBJECTIVES: To estimate the size of the populations targeted by the French recommendations of the High Council for Public Health (French acronym HCSP) regarding vaccination against seasonal flu and to estimate vaccination coverage rates in these populations. PATIENTS AND METHODS: The analysis was conducted on a representative sample of patients retrieved from the French Health Insurance databases during three influenza seasons (2012-2013, 2013-2014, 2014-2015). Patients targeted by the influenza vaccination recommendations were identified based on their sociodemographic characteristics and disease identification algorithms during each season. Vaccine coverage rates were estimated based on reimbursed influenza vaccines. Results were extrapolated using indirect standardization to the overall French population. RESULTS: Populations targeted by the recommendations were estimated after extrapolation to 17.6, 17.8, and 18.0 million for the 2012-13, 2013-14, and 2014-15 influenza seasons, respectively. The vaccination coverage rates in these target populations were respectively estimated at 32.1%, 31.9%, and 32.1%; i.e. 44.2%, 43.1%, and 42.7% for individuals aged ≥65 years and 12.9%, 13.2%, and 13.7% for individuals ˂65 years of age presenting a risk justifying vaccination. CONCLUSIONS: Immunization coverage against influenza in France remains well below the target of 75% set by the World Health Organization. Multiple strategies combining communication, education, access program, and professional engagement could be implemented to improve this situation.

[Economic consequences of biological monitoring and medical complications of injectable anticoagulants in France]. / Conséquences économiques du suivi biologique et des complications médicales en lien avec l'utilisation des anticoagulants injectables en France.

AIM: To assess the frequency of platelet monitoring and bleeding risks associated with the use of injectable anticoagulants in a real life setting and to estimate the associated costs. METHOD: An analysis of the 2013 data from a random sample of ≈600,000 patients registered in the French National Health Insurances reimbursement database was conducted to identify platelet counts performed during injectable anticoagulants exposure period and treatment interruptions due to heparin-induced thrombocytopenia or transfusion. Events were then valued to establish associated costs. RESULTS: Overall 15,985 adult patients representing a cumulated injectable anticoagulants exposure time of 12,264 months were selected. Treatment sequences involved unfractionated heparin (2.8%), low molecular weight heparin (86.9%), and fondaparinux (13.1%). Patients treated with unfractionated heparin were older (77 vs. 57 and 59 years) with longer treatment duration (32.6 vs. 25.1 and 21 days). After statistical adjustment, the average monthly number of platelet counts was 1.36-fold lower in patients treated with fondaparinux compared to low molecular weight heparin (P<0.0001). No difference was found between low molecular weight heparin and fondaparinux regarding the incidence of bleeding with transfusion (P=0.76) or hospitalized thrombocytopenia (P=0.82). Extrapolated for the whole country, the estimated costs for biological monitoring were € 21.6 million for low molecular weight heparin and € 0.9 million for fondaparinux. CONCLUSION: Significantly fewer platelet counts were performed among patients treated with fondaparinux than among patients receiving low molecular weight heparin without additional bleeding risk. This finding should be taken into account when assessing the costs of such treatments.

Impact of socio-economic position on health and quality of care in adults with Type 2 diabetes in France: the Entred 2007 study.

AIM: To describe the association between socio-economic position, health status and quality of diabetes care in people with Type 2 diabetes in France, where people may receive full healthcare coverage for chronic disease. METHODS: Data from a national cross-sectional survey performed in people pharmacologically treated for diabetes were used. They combined data from medical claims, hospital discharge, questionnaires for patients (n = 3894 with Type 2 diabetes) and their physicians (n = 2485). Socio-economic position was assessed using educational level (low, intermediate, high) and ability to make ends meet (financial difficulties vs. financially comfortable). RESULTS: People with diabetes reporting financial difficulties were more likely to be smokers (adjusted odds ratio 1.4; 95% CI 1.1-1.6) and obese (adjusted odds ratio 1.3; 95% CI 1.2-1.6) and to have poorer glycaemic control (HbA1c > 64 mmol/mol (8%); adjusted odds ratio 1.4; 95% CI 1.1-1.8), than those who were financially comfortable. They were more likely to have their diabetes diagnosed because of complications (adjusted odds ratio 1.6; 95% CI 1.3-2.0). They were also more likely to have coronary and podiatric complications (adjusted odds ratios 1.3; 95% CI 1.1-1.6 and 1.7; 95% CI 1.4-2.2, respectively). They benefited more often from full coverage (adjusted odds ratio 1.3; 95% CI 1.1-1.6), visited general practitioners more often (ratio of estimated marginal means 1.2; 95% CI 1.1-1.2) but specialists less often (adjusted odds ratio 0.7; 95% CI 0.6-0.8 for a visit to private ophthalmologist). They also felt less well informed about their condition. CONCLUSIONS: Despite frequent access to full healthcare coverage, socio-economic position has an impact on the diagnosis of diabetes, health status and quality of diabetes care in France.

[Management and costs of chronic pulmonary obstructive disease in France in 2011]. / Prise en charge et coûts de la bronchopneumopathie chronique obstructive en France en 2011.

OBJECTIVES: To estimate the prevalence of treated chronic obstructive pulmonary disease (COPD) and its associated costs by stage of severity. METHODS: The study was conducted on the 2011 data of the french general beneficiary sample database (EGB). EGB is a 1/97th sample of the whole population of the beneficiaries of the main compulsory national health insurances. COPD cases and the level of severity of the disease have been identified using new algorithms established from the available parameters in EGB. Costs were estimated using a collective perspective. RESULTS: The minimal prevalence of treated COPD was estimated at 3.8% in patients of 40 years and older and 1.9% regardless of the age of individuals. This population was predominantly male (58.2%) with a mean age of 68.8 years (±12.7). A total of 6.2% of patients had a health-care utilization suggestive of a very severe stage of COPD and 8.1%, 13.8% and 71.9% suggestive of severe, moderate and mild stages respectively. Over one year, 28.8% of patients visited a specialist respiratory physician, 5.0% were hospitalized (≥24h) for COPD and 6.7% died. Patients experienced an average of 1.7 (±1.5) exacerbations per year and only 61.4% received specific pharmacological treatment for COPD during the year. The average yearly health-care cost of a patient with COPD was estimated at €9382, with €5342 directly related to COPD. CONCLUSION: This study based on medico-administrative databases confirms the high epidemiological and economic burden of COPD in France.

Type 2 diabetes prevalence, health status and quality of care among the North African immigrant population living in France.

AIM: This report is an overview of type 2 diabetes (DT2) in the North African immigrant population living in France. METHODS: Data were collected in two separate cross-sectional national surveys. DT2 prevalence was estimated using a population-based survey involving 13 959 people aged ≥ 45 years (EDS), while health status and quality of care were evaluated using a sample of 3894 DT2 patients (ENTRED). RESULTS: Prevalence of DT2 and obesity was 14.0% [CI 95%: 9.9; 18.0] and 20.5% [15.7; 25.3], respectively, in participants born in North Africa (BNA) and 7.5% [7.0; 8.0] and 15.8% [14.7; 16.8], respectively, in those born in France (BIF). DT2 was associated with region of birth in women after adjusting for age, body mass index and income or occupation, but not after adjusting for education level. In men, DT2 was not associated with region of birth. BNA and BIF patients with diabetes frequently benefited from free medical coverage (88% vs. 84%, respectively), although BNA diabetic patients visited a general practitioner less frequently than BIF (8.5 vs. 9.0 visits/year, respectively). The percentage of BNA vs. BIF diabetes patients tested three times a year for HbA1c was lower (39% vs. 44%), while HbA1c was higher in BNA vs. BIF diabetics (> 8%: 30% vs. 15%). Ophthalmological complications were also more frequent in BNA vs. BIF patients with diabetes (25% vs. 18%, respectively). CONCLUSION: The greater prevalence of DT2 in BNA women and the poorer glycaemic control observed in the BNA population overall both probably contribute to disparity in diabetes mortality compared with BIF diabetics, a fact that has been observed in previous studies.

Glucose lowering therapeutic strategies for type 2 diabetic patients with chronic kidney disease in primary care setting in france: a cross-sectional study.

Aim. To understand glucose lowering therapeutic strategies of French general practitioners (GPs) in the management of type 2 diabetes mellitus (T2DM) patients with chronic kidney disease (CKD). Methods. A multicenter cross-sectional study was conducted from March to June 2011 among a sample of French GPs who contribute to the IMS Lifelink Disease Analyzer database. Eligible patients were those with T2DM and moderate-to-severe CKD who visited their GPs at least once during the study period. Data were collected through electronic medical records and an additional questionnaire. Results. 116 GPs included 297 patients: 86 with stage 3a (Group 1, GFR = 45-60 mL/min/1.73 m(2)) and 211 with stages 3b, 4, or 5 (Group 2, GFR < 45 mL/min/1.73 m(2)). Patients' mean age was approximately 75 years. Insulin was used in 19% of patients, and was predominant in those with severe CKD. More than two-thirds of patients were treated with glucose lowering agents which were either contraindicated or not recommended for CKD. Conclusion Physicians most commonly considered the severity of diabetes and not CKD in their therapeutic decision making, exposing patients to potential iatrogenic risks. The recent patient oriented approach and individualization of glycemic objectives according to patient profile rather than standard HbA1c would improve this situation.

Therapeutic management of orally treated type 2 diabetic patients, by French general practitioners in 2010: the DIAttitude Study.

AIM: To describe the behaviour of French general practitioners (GP) regarding intensification of hypoglycaemic agents in orally treated type 2 diabetic (T2D) patients, according to their HbA(1c) level. METHODS: General practitioners were recruited from a panel of office-based general practitioners. T2D patients who had been orally treated for at least 6 months were included in the study; their characteristics were recorded, and their HbA(1c) values and hypoglycaemic treatments over the previous 24 months extracted from electronic records The major reasons for intensification (or no intensification) of hypoglycaemic agents were recorded at the inclusion visit. RESULTS: A total of 236 general practitioners recruited 2109 T2D patients: 1732 had at least one HbA(1c) value recorded in the previous 6 months, and 52%, 33% and 14% had been treated, with oral hypoglycaemic agents in monotherapy, bitherapy or tri-or quadritherapy, respectively. Of these patients, 702 (41%) remained uncontrolled (47%, 39% and 20% respectively) and according to the current French guidelines needed treatment intensification. Only 46 (7%) had their treatment intensified at inclusion. Of those without intensified treatment, 60% were treated with monotherapy; the main reason given by the general practitioners for not intensifying treatment was a satisfactory HbA(1c) level (53%), although 32% had an HbA(1c)>7%. Other reasons were: lifestyle advice had greater priority (20%); decision was postponed until the next visit (11%); HbA(1c) had decreased since last visit (7%; not confirmed by available data in 58% of cases); a medical priority other than diabetes (6%) and other reasons related to the patient (3%). CONCLUSION: For T2D patients managed by French general practitioners, guidelines are not consistently followed: HbA(1c) should be monitored more frequently and treatment adjusted according to HbA(1c) levels.

A real-life study of the use, effectiveness and tolerability of rosiglitazone in France: the AVANCE study.

AIM: The study aimed to determine the effectiveness and tolerability of rosiglitazone, and its profile in terms of treatment adherence, treated patients and prescribing recommendations under everyday conditions of care. METHODS: This was a "real-life" observational longitudinal study including patients with type 2 diabetes mellitus (T2DM) starting treatment with rosiglitazone and followed for up to 2 years. A questionnaire was completed at the time of inclusion and during routine consultations at around 6, 12, 18 and 24 months following inclusion. Information was collected on sociodemographics, clinical history, treatments, co-morbidities, laboratory data and compliance with treatment. There were three primary outcome measures: treatment response (defined as an HbA1c ≤ 8.0% or a decrease in HbA1c ≥ 0.7%); switch to insulin (as considered necessary by the physician); and occurrence of adverse events requiring a change or discontinuation of treatment. RESULTS: The evaluation included 670 patients (61.1%) treated with rosiglitazone/metformin as fixed-dose combination tablets and 427 (38.9%) with standard rosiglitazone tablets. Rates of HbA1c response, defined as an HbA1c less than or equal to 8.0% or a decrease in HbA1c greater than or equal to 0.7%, ranged from 80.6% to 92.1% depending on the follow-up time. The percentage of patients with an HbA1c less than 7% was 18.4% before rosiglitazone was prescribed, and ranged from 48.2% to 57.8% depending on the follow-up period. Sixty-two patients (6.1%, 95% CI: 4.6-7.6%) switched to insulin therapy during the follow-up period. Spontaneously reported adverse events leading to a change or discontinuation of treatment were seen in 45 patients (4.4%, 95% CI: 3.2-5.6%). CONCLUSION: Rosiglitazone showed sustained efficacy, with around 90% of patients defined as responders to the treatment in terms of reduction in HbA1c, and was relatively well tolerated. The adverse-event profile was consistent with the known effects of rosiglitazone, and no signs of increased cardiovascular ischaemic risk were observed. These results are in agreement with previous studies on rosiglitazone.

[Management of immune thrombocytopenia in France before the era of thrombopoietin receptor agonists]. / Prise en charge du purpura thrombopénique immunologique en France avant la mise à disposition des agonistes du récepteur à la thrombopoïétine.

PURPOSE: Adult immune thrombocytopenia (ITP) is an auto-immune disease with most often a chronic course for which a consensual therapeutic strategy is missing. The objective of this study was to describe treatment practices in adult ITP in France before the era of thrombopoietin receptor (TpoR) agonists. METHODS: A retrospective observational study was conducted in eight hospitals in France. All eligible patients were at least 18 years of age and were seen for a chronic ITP between January 2004 and March 2006 in one of the participating centers. Data were collected retrospectively from clinical charts. ITP treatment from disease onset was analyzed for every patient according to the time of diagnosis. RESULTS: The study included 122 patients (73% of women) with a mean age of 52.6 years. Patients in whom ITP had been diagnosed less than 4 years earlier (n=71) received on average 2.9 treatment lines. Corticosteroids possibly combined with intravenous immunoglobulins were most often used as a first-line. From the second line, up to 12 different regimens were identified. As a third line, rituximab and splenectomy were the most common therapeutic procedures. The number of splenectomy tended to decrease over time. CONCLUSION: This analysis reflects the great heterogeneity into the management of chronic ITP. Whether such heterogeneity has declined after national guidelines have been produced remains to be assessed as well as the place of the newly develop TpoR agonists.

Chronic kidney disease in type 2 diabetes patients in France: prevalence, influence of glycaemic control and implications for the pharmacological management of diabetes.

AIM: Type 2 diabetes mellitus (T2DM) is often associated with chronic kidney disease. For this reason, this article reviews the relationship between treatment of T2DM and renal disease. METHOD: The review presents the recent French data on the management of diabetes in patients with renal impairment, and discusses the implications of renal disease for the treatment of such patients. Prescribing data are presented for various antidiabetic treatments, and the use of the more commonly prescribed medications is discussed with reference to T2DM patients with renal disease. RESULTS: In France, it is estimated that 4-5% of the general population has T2DM and that almost 40% of patients with end-stage renal failure have diabetes. Diabetes and renal disease are both risk factors for cardiovascular morbidity and mortality. Glycaemic control is pivotal in T2DM patients for minimizing the risk of vascular complications and hypoglycaemic episodes, particularly in patients with renal disease who also have a higher risk of hypoglycaemia. Whereas poorly controlled glycaemia increases the risk of renal disease and its progression, the risk is diminished in patients treated intensively for diabetes and in those who achieve stable glycaemic control. Intensive multitargeted treatment can also help to decrease cardiovascular morbidity and mortality, especially if started early in patients who have not yet developed macrovascular complications. CONCLUSION: In recent years, considerable improvement has been observed in France regarding the follow-up of diabetic patients. Less extensive, but nonetheless significant, improvement has also been observed in glycaemic control. However, even though treatment decisions generally take renal function into account, some at-risk treatments are often still being used in patients with renal insufficiency.

Insulin therapy for diabetes mellitus: treatment regimens and associated costs.

AIMS: To describe insulin therapy in patients with diabetes, to determine treatment costs and to compare costs among treatment regimens. METHODS: This observational study was performed by 734 French pharmacists. Adult patients filling an insulin prescription were invited to participate. Participants provided information on their diabetes history and management. Levels of intensification of insulin therapy were determined by the number of injections in type 1 diabetes mellitus (T1DM) patients, and by the different schemes used in type 2 (T2DM) patients, such as basal/intermediate-acting insulin only, and regimens using both basal and rapid-acting insulin. Costs were evaluated according to official medication costs, nurse visits and glucose monitoring kits. RESULTS: A total of 361 patients with T1DM and 1902 with T2DM were enrolled in the survey. Patients with T1DM more frequently took 1-2 injections per day (46.3% of patients) and used single-dose basal insulin together with ≥1 dose of rapid insulin (43.8%). Patients with T2DM used multiple treatment regimens, with 58 different combinations documented. Most took basal/intermediate insulin only (42.5%) or combinations of basal/intermediate and rapid insulins (52.7%). Mean cost of insulin therapy was €27.4/week for T1DM and €45.4/week for T2DM. In T1DM, insulin was the biggest cost component and increased with the number of injections/day. In T2DM, nurse visits were the most important cost contributors irrespective of treatment regimen. Overall, the cost of insulin therapy increased with the complexity of the insulin schemes. CONCLUSION: Considerable heterogeneity is found in insulin treatment regimens used in everyday diabetes care. Payers should consider the full costs associated with the use of insulin rather than the cost of insulin alone. Treatment algorithms to harmonize insulin therapy should help to improve care, while encouraging patients to self-inject insulin should help to reduce costs.

[The costs of asthma in France and the economic implications of its level of control]. / Le coût de l'asthme en France et les implications économiques du niveau de contrôle.

INTRODUCTION: The prevalence of asthma is increasing in France and the proportion of patients with poorly controlled or uncontrolled asthma remains significant. The economic impact of this public health issue is still poorly documented and this is addressed in the present literature review. STATE OF THE ART: Older identified studies aimed to estimate the use of asthma-related health care resources according to the asthma severity. Only more recent studies have taken into account the level of control of the disease as well. A consistent finding was that asthma-related medical costs were highly dependent both on the degree of severity and level of control. PERSPECTIVES: Studies identified in this review used the recommendations current at the time of their publication to define severity or levels of control in connection to asthma-related medical consumption, which leads to important methodological variation among them. Economic evaluation which is generally based on annual consumption estimates is hampered by the fact that the level of control reflects only a short-term situation. CONCLUSIONS: Although data in the literature are consistent in showing that improved control of the disease significantly reduces the costs of its management, there is a need for economic studies based on recent definitions of control and using appropriate methodology.

[Validation study of the BDI/TDI scores in chronic obstructive pulmonary disease]. / Etude de validation de l'échelle BDI/TDI dans la bronchopneumopathie chronique obstructive.

BACKGROUND: The Baseline and Transition Dyspnoea Indices (BDI/TDI) provide measurements of breathlessness and of its impact on activities of daily living. OBJECTIVES: To assess, in France, the measurement characteristics of the BDI/TDI scores. METHOD: A multicentric cohort of 103 patients with mild to severe COPD was questioned by both a medical and a paramedical investigator at enrollment and again 6 months later. RESULTS: Concordance between investigators was good for all the sub-scores of the BDI, but less satisfactory for the TDI score. The BDI score was significantly correlated with all spirometric data. Conversely, the TDI score only correlated significantly with change in the FEV1. Both scores correlated highly with the modified Medical Research Council score, the St George Respiratory Questionnaire and with their evolution. The average TDI score was close to 0 in stable patients indicating good reproducibility of this Index. Changes in the TDI score were closely associated with changes in global health assessment by physicians, less so when assessed by patients. CONCLUSION: The BDI-TDI scores appear to be valid instruments for the measurement of dyspnoea in COPD patients and, less significantly, for measurement of its change over time.

[Assessing the incidence of papillomavirus infections in France]. / Estimation de l'incidence des infections à papillomavirus en France.

High-risk oncogenic human papillomavirus (HR-HPV) are strongly associated with squamous cell carcinoma and adenocarcinoma of the uterine cervix. Relatively detailed data on prevalence of HR-HPV infections by age in France are available in several cytologically normal women populations but none on incidence. These latter data may be obtained according to the relationship between prevalence and incidence due to the spontaneous viral clearance over time. The study has shown that HR-HPV infections incidence changes slightly according to the selected hypotheses for the viral clearance and that a peak is reached at about 12% for the women aged 22. A relatively high incidence is observed at older age classes with about 4% at 60 years old. These results are close to that observed in other countries even if the incidence peak appears slightly lower and happens later. Nevertheless, the model did not include possible viral reactivation or reinfection that could modify the incidence curve angle. The incidence of the HR-HPV infections is essential to define vaccination strategies and to determine the women ages at which the vaccine could be optimally administered.

Prevalence of diagnosed type 2 diabetes mellitus in the French general population: the INSTANT study.

AIMS: To estimate the prevalence of diagnosed type 2 diabetes mellitus in the French general population. Secondary objectives were to evaluate treatments and diabetic complications. METHODS: In this cross-sectional epidemiological survey, a representative sample of the French adult population was selected using a stratified quota method: 10,038 individuals were evaluated by a standardized face-to-face interview. The diagnosis of type 2 diabetes was determined on the basis of replies to six questions using a specific algorithm. Data were collected on risk factors, diabetes history, familial antecedents and diabetic complications. These patients also identified their treatments from an exhaustive list. RESULTS: The prevalence of type 2 diabetes was 5.08% in men and 4.11% in women, and rose progressively after the age of 50. Of these, 79 patients (13.4%) received no pharmacological treatment, 477 (80.9%) were taking an oral antidiabetic drug and 134 (22.7%) were taking insulin. Renal and ocular complications were reported by 6.8% and 21.0%, respectively, of the patients. Also, 10.4% had been hospitalized at some time of that year for a diabetes-related problem. The most frequently reported treatments were metformin and sulphonylureas, used by more than 50% of the patients. In addition, 380 patients (65.9%) claimed to be following a diet and 228 (39.2%) were consulting a dietitian. CONCLUSION: The prevalence of treated and untreated type 2 diabetes mellitus in France was 4.57%.

Prevalence of macrovascular complications and cardiovascular risk factors in people treated for diabetes and living in France: the ENTRED study 2001.

AIM: The aim of this study is to estimate the prevalence of macrovascular complications and cardiovascular risk factors among people with diabetes living in France and to compare these prevalences with other national estimates. METHODS: We randomly sampled 10,000 people who received one or more reimbursements for insulin or oral hypoglycaemic treatment from the major national medical insurance system during the period October-December 2001; 3646 of the 10,000 people completed a questionnaire; for a subgroup of 1718 people, their care providers completed a medical questionnaire. RESULTS: The prevalence of diagnosed macrovascular complications was of 17% according to patients (angina or myocardial infarction, 15%; coronary revascularization, 9%) and of 20% overall, according to physicians (angina or myocardial infarction, 16%; coronary revascularization, 6%; stroke, 5%). Macrovascular complications were more frequent in people with type 2 than type 1 diabetes, reflecting an age effect. The prevalences of cardiovascular risk factors in type 1 and type 2 diabetes were: current smoking, 35 and 14%; overweight, 28 and 42%; obesity, 9 and 36%; blood pressure superior to 130/80 mmHg, 29 and 59%; LDL cholesterol superior or equal to 3.4 mmol/l, 18 and 26%, respectively. CONCLUSIONS: Compared with other European countries, elevated blood pressure is more frequent in people with diabetes living in France; compared with US estimates, the prevalence of macrovascular complications is lower, glucose control better and blood pressure control poorer in France. These data, observed in a country with widespread access to care and at low cost to the patient, nevertheless demonstrate an urgent need for improving the cardiovascular risk profile of people with type 1 and type 2 diabetes, both with and without macrovascular complications.
