Background: Patients with non-valvular atrial fibrillation who are receiving or have been previously exposed to a vitamin K antagonist could be switched to a non-vitamin K-antagonist oral anticoagulant (NOAC) but little information is available about the risk of bleeding and arterial thromboembolism after such a switch. We aimed to compare the risk of bleeding between individuals who switched and those who remained on a vitamin K antagonist (non-switchers) in real-world conditions.

Methods: We did a matched-cohort study with information from French health-care databases.

Background: The most used score to measure comorbidity is the Charlson index. Its application to a health care administrative database including International Classification of Diseases, 10th edition (ICD-10) codes, medical procedures, and medication required studying its properties on survival. Our objectives were to adapt the Charlson comorbidity index to the French National Health Insurance database to predict 1-year mortality of discharged patients and to compare discrimination and calibration of different versions of the Charlson index.

Objectives: Severe sprue-like enteropathy associated with olmesartan has been reported, but there has been no demonstration of an increased risk by epidemiological studies.

Aim: To assess, in a nationwide patient cohort, the risk of hospitalisation for intestinal malabsorption associated with olmesartan compared with other angiotensin receptor blockers (ARB) and ACE inhibitors (ACEIs).

Design: From the French National Health Insurance claim database, all adult patients initiating ARB or ACEI between 1 January 2007 and 31 December 2012 with no prior hospitalisation for intestinal malabsorption, no serology testing for coeliac disease and no prescription for a gluten-free diet product were included.

Background: Few data exist on how elderly patients with colorectal cancer (CRC) are actually treated in real-life practice. Based on a national cohort, we analysed routine treatment modalities of the elderly who were diagnosed with CRC in France in 2009.

Patients And Methods: The characteristics of patients and tumours and the cancer treatments received during the first year of all national incident cases of CRC diagnosed between 1st April and 31st December 2009, were compared between a 'younger group' (YG), under 75 years of age (N = 18,410 patients), and an 'older group' (OG), aged 75 and over (N = 13,255 patients).

Purpose: Using the French claims database (Système National d'Information Inter-Régimes de l'Assurance Maladie) linked to the hospital discharge database (Programme de Médicalisation des Systèmes d'Information), this observational study compared the effectiveness of rosuvastatin and simvastatin prescribed at doses with close LDL-cholesterol-lowering potency on all-cause mortality and cardiovascular and cerebrovascular diseases (CCDs) in primary prevention.

Methods: This historical cohort included patients with no prior CCD, aged 40-79 years, who initiated statin therapy with rosuvastatin 5 mg or simvastatin 20 mg in 2008-2009 in general practice. Follow-up started after a 1-year period used to select patients who regularly received the initial treatment.

Aim: To measure the seasonal influenza vaccination coverage rate (VCR) in France in 2010, one year after the A(H1N1) influenza pandemic, and 2011 by age and target disease and to identify risk factors associated with a lack of vaccination in 2010 for those previously vaccinated in 2009.

Methods: At the beginning of each vaccination campaign, the National Health Insurance, covering 86% of the French population, sends free influenza vaccination vouchers to at-risk beneficiaries aged under 65 suffering from diverse target diseases and to all individuals aged 65 and over (around 11.5 million).

Background: The type of medical coverage in patients with acute myocardial infarction (AMI) may affect their treatment and outcome.

Methods And Results: We used the reimbursement database from the French National Health Insurance to determine the impact of full medical coverage (Couverture Médicale Universelle Complémentaire, CMUC), a free supplemental insurance for low-income earners <60 years of age, on treatment and outcomes of patients with AMI. The population comprised consecutive patients <60 years of age hospitalized for AMI from January to June 2006 in France.
