These databases were linked by means of a unique anonymous number allocated to each individual, providing detailed information on health insurance claims for inpatient (PMSI) and outpatient (SNIIRAM) care for 99% of the population living in France (about 67,000,000 people).

The SNIIRAM database merges anonymous information of reimbursed claims from all these plans, linked to the national hospital?discharge summaries database system (PMSI) and the national death registry. It now covers 98.8% of the French population, over 66 million persons, from birth (or immigration) to death (or emigration), making it possibly the world's largest continuous homogeneous claims database. The database includes demographic data; health care encounters such as physician or paramedical visits, medicines, medical devices, and lab tests (without results); chronic medical conditions (ICD10 codes); hospitalisations with ICD10 codes for primary, linked and associated diagnoses, date and duration, procedures, diagnostic?related groups, and cost coding; date but currently not cause of death. The power of the database is correlatively great, and its representativeness is near perfect, since it essentially includes the whole country's population. The main difficulty in using the database, beyond its sheer size and complexity, is the administrative process necessary to access it. Recent legislative advances are making this easier. EGB (Echantillon Généraliste de Bénéficiaires) is the 1/97th random permanent representative sample of SNIIRAM, with planned 20?year longitudinal data (10?years at this time). Access time is 1 to 3?months, but its power is less (780?000 subjects). This is enough to study common issues with older drugs but may be limited for new products or rare events.","DOI":"10.1002/pds.4233","ISSN":"1053-8569","title-short":"The national healthcare system claims databases in France, SNIIRAM and EGB","journalAbbreviation":"Pharmacoepidemiology and Drug Safety","author":[{"family":"Bezin","given":"Julien"},{"family":"Duong","given":"Mai"},{"family":"Lassalle","given":"Régis"},{"family":"Droz","given":"Cécile"},{"family":"Pariente","given":"Antoine"},{"family":"Blin","given":"Patrick"},{"family":"Moore","given":"Nicholas"}],"issued":{"date-parts":[["2017",8,8]]}}}],"schema":""} 1 and Moulis et al.

Drug exposure is often presumed from health insurance claims but this may not correspond exactly to what subjects actually take. This study was designed to investigate French reimbursement databases in assessing drug use. Methods Between 1999 and 2001, 9294 subjects were included in the Three?City (3C) Study, a French cohort studying the relationship between vascular risk factors and dementia. Of these, 4112 subjects had data available from both clinical interviews and the reimbursement databases of the French national health insurance system. Agreement between drugs reported as used at interview and drugs reimbursed during the previous 30 or 60?days was measured with ? coefficients. Using calculations of sensitivity (Se), specificity (Sp), positive predictive values (PPVs) and negative predictive values (NPVs), the validity of reimbursement data for the 30 or 60?days preceding the interview was investigated taking drugs reported at interview as the ?gold standard?. Results Declared drug use at interview was less well predicted by 30?day than by 60?day reimbursement data. Agreement between reimbursement data and interviews as well as validity of reimbursement data with reference to interviews were substantial for drugs used in cardiovascular diseases, diabetes, rheumatic disorders or neuropsychiatric conditions and were poor for laxatives, vitamins, vasculoprotectives, first and second line analgesics, anti?infective products or dermatologicals. Conclusions Reimbursement data with an appropriate time frame and interviews estimate exposure to chronically used drugs similarly. Self?medication was better described with interviews whereas reimbursement data seem more useful for drugs used topically or intermittently.

Dates available for hospital stays are admission date, discharge date, and procedure (e.g. colonoscopy) date. For the purposes of this study, admission date was used as an approximation for the SAE date.Almost all persons living in France are covered by one of the various national health insurance schemes. Each national health insurance scheme reimburses almost all medical care (including colonoscopies) at the same rate for both public and private care. Persons with limited income or LTD are 100% reimbursed. The general scheme is the largest health insurance scheme in France (covering 76% of the population living in France). This scheme includes employed workers, retired, unemployed, and disadvantaged people. Follow-up of beneficiaries is stable, as people rarely leave this scheme. Other schemes (mainly farmers and self-employed) are more specific. The present study was restricted to the general scheme, as reliable information (notably on death date) for the entire study period is only available for this scheme.SNDS data are commonly used for non-interventional studies in various conditions.

Among patients receiving antidiabetes treatment at baseline, the antidiabetes treatment discontinuation rate was higher 6 years after bariatric surgery than in controls (-49.9% vs -9.0%, P?<?.001). In multivariable analysis, the main predictive factors for discontinuation were the following: GBP (odds ratio [OR], 16.7; 95% CI, 13.0-21.4), SG (OR, 7.30; 95% CI, 5.50-9.50), and AGB (OR, 4.30; 95% CI, 3.30-5.60) compared with no bariatric surgery, as well as insulin use (OR, 0.17; 95% CI, 0.13-0.22), dual therapy without insulin (OR, 0.38; 95% CI, 0.32-0.45) vs monotherapy, lipid-lowering treatment (OR, 0.76; 95% CI, 0.63-0.91), antidepressant treatment (OR, 0.67; 95% CI, 0.55-0.81), and age (OR, 0.96; 95% CI, 0.95-0.97) per year. For patients without antidiabetes treatment at baseline, the 6-year antidiabetes treatment initiation rate was much lower after bariatric surgery than in controls (1.4% vs 12.0%, P?<?.001). In multivariable analysis, protective factors were GBP (OR, 0.06; 95% CI, 0.04-0.09), SG (OR, 0.08; 95% CI, 0.06-0.11), and AGB (OR, 0.16; 95% CI, 0.14-0.20) vs controls, and risk factors were as follows: body mass index category (OR, 2.04; 95% CI, 1.68-2.47 for ≥50.0 vs 30.0-39.9 and OR, 1.68; 95% CI, 1.49-1.90 for 40.0-49.9 vs 30.0-39.9), antihypertensive treatment (OR, 1.49; 95% CI, 1.33-1.67), low income (OR, 1.43; 95 % CI, 1.26-1.62), and age (OR, 1.04; 95 % CI, 1.03-1.05) per year.\nConclusions and Relevance: Bariatric surgery was associated with a significantly higher 6-year postoperative antidiabetes treatment discontinuation rate compared with baseline and with an obese control group without bariatric surgery.","DOI":"10.1001/jamasurg.2017.6163","ISSN":"2168-6262","note":"PMID: 29450469\nPMCID: PMC5875344","journalAbbreviation":"JAMA Surg","language":"eng","author":[{"family":"Thereaux","given":"Jérémie"},{"family":"Lesuffleur","given":"Thomas"},{"family":"Czernichow","given":"Sébastien"},{"family":"Basdevant","given":"Arnaud"},{"family":"Msika","given":"Simon"},{"family":"Nocca","given":"David"},{"family":"Millat","given":"Bertrand"},{"family":"Fagot-Campagna","given":"Anne"}],"issued":{"date-parts":[["2018",2,14]]}}},{"id":539,"uris":[""],"uri":[""],"itemData":{"id":539,"type":"article-journal","title":"Dental procedures, antibiotic prophylaxis, and endocarditis among people with prosthetic heart valves: nationwide population based cohort and a case crossover study","container-title":"BMJ (Clinical research ed.)","page":"j3776","volume":"358","source":"PubMed","abstract":"Objective\n?To assess the relation between invasive dental procedures and infective endocarditis associated with oral streptococci among people with prosthetic heart valves.Design?Nationwide population based cohort and a case crossover study.Setting?French national health insurance administrative data linked with the national hospital discharge database.Participants?All adults aged more than 18 years, living in France, with medical procedure codes for positioning or replacement of prosthetic heart valves between July 2008 and July 2014.Main outcome measures?Oral streptococcal infective endocarditis was identified using primary discharge diagnosis codes.

These comprehensive national databases are powerful tools to assess the prevalence of rare events. As the primary purpose of these databases is financial, any false statements constitute serious frauds, liable to legal proceedings, which also tends to ensure the accuracy of the data recorded. Furthermore, quality controls and audits are performed before transmission to National Health Insurance (CNAM, Caisse Nationale de l’Assurance Maladie), mainly for processing of aberrant or missing data. Descriptive statisticsCrude SAE rates per 10,000 colonoscopies were calculated by dividing the total numbers of adverse events by the total number of colonoscopies in the cohort. Standardized incidence ratios (SIRs) were calculated to compare these incidence rates with the incidence rates of these events in 2013 in the general population (general scheme beneficiaries aged 30 years and over, i.e. 32,490,167 individuals), which served as the reference group (reference rates were stratified by gender and 5-year age-groups). More precisely, SIRs were estimated by dividing the observed number of SAEs by the expected number of SAEs, obtained by applying the incidence rate observed in the general population (in this case, the general scheme beneficiaries) to the number of individuals in our cohort in each age and gender group considered. Crude 5-day and 30-day mortality rates per 1,000 SAE were calculated for each SAE by dividing the total numbers of deaths occurring within 5 or 30 days after a SAE by the total number of SAE in the cohort. Crude 5-day and 30-day mortality rates per 100,000 procedures were also calculated for each SAE by dividing the total numbers of deaths occurring within 5 or 30 days after a SAE by the total number of colonoscopies in the cohort. Crude odds ratios (OR) for each SAE studied were estimated by logistic regression models for patient, colonoscopy, endoscopist, and facility characteristics.References1.
