Two-year outcome of patients after a first hospitalization for heart failure: A national observational study

BACKGROUNDnNational population-based management and outcome data for patients of all ages hospitalized for heart failure have rarely been reported.nnnAIMnNational population-based management and outcome of patients of all ages hospitalized for heart failure have rarely been reported. The present study reports these results, based on 77% of the French population, for patients hospitalized for the first time for heart failure in 2009.nnnMETHODSnThe study population comprised French national health insurance general scheme beneficiaries hospitalized in 2009 with a principal diagnosis of heart failure, after exclusion of those hospitalized for heart failure between 2006 and 2008 or with a chronic disease status for heart failure. Data were collected from the national health insurance information system (SNIIRAM).nnnRESULTSnA total of 69,958 patients (mean age, 78 years; 48% men) were studied. The hospital mortality rate was 6.4%, with 1-month, 1-year and 2-year survival rates of 89%, 71% and 60%, respectively. Heart failure and all-cause readmission-free rates were 55% and 43% at 1 year and 27% and 17% at 2 years, respectively. Compared with a reference sample of 600,000 subjects, the age- and sex-standardized relative risk of death was 29 (95% confidence interval [CI] 28-29) at 2 years, 82 (95% CI 72-94) in subjects aged<50 years and 3 (95% CI 3-3) in subjects aged ≥ 90 years. For subjects aged < 70 years who survived 1 month after discharge, factors associated with a reduction in the 2-year mortality rate were: female sex; age < 55 years; absence of co-morbidities; and use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, beta-blockers, lipid-lowering agents or oral anticoagulants during the month following discharge. Poor prognostic factors were treatment with a loop diuretic before or after hospitalization and readmission for heart failure within 1 month after discharge.nnnCONCLUSIONSnThis large population-based study confirms the severe prognosis of heart failure and the need to promote the use of effective medications and management designed to improve survival.

Estimating the prevalence of depression associated with healthcare use in France using administrative databases

BackgroundQuantitative indicators are needed in order to define priorities, plan policies and evaluate public health interventions in mental health. The aim of this study was to assess the contribution of a large and exhaustive French national administrative database to study and monitor treated depression by comparing the prevalence and characteristics of the population using significant healthcare resources for depression as identified by different estimation methods and sources and to discuss the advantages and drawbacks of these methods.MethodsThis study included the French population covered by the main health insurance scheme in 2012 (Régime général, 86% of the insured French population). Data were extracted from the French health insurance claim database (SNIIRAM), which contains information on all reimbursements, including treatments and hospital stays in France. The following distinct sources of the SNIIRAM were used to select persons with depression: diagnoses of long-term or costly conditions, data from national hospital claims and data concerning all national health insurance reimbursements for drugs.ResultsIn 2012, we included 58,753,200 individuals covered by the main health insurance scheme; 271,275 individuals had full coverage for depression; 179,470 individuals had been admitted to a psychiatric hospital and 66,595 individuals admitted to a general hospital with a diagnosis of depression during a 2-year timeframe and 144,670 individuals had more than three reimbursements for antidepressants during the study year (with a history of hospitalisation for depression during the past 5xa0years). Only 16% of individuals were selected by more than one source.ConclusionsWe propose an algorithm that includes persons recently hospitalised for depression, or with a history of hospitalisation for depression and still taking antidepressants, or with full coverage for depression as a specific long-term or costly condition, yielding a prevalence estimate of 0.93% or 544,105 individuals. Changes in the case selection methodology have major consequences on the frequency count and characteristics of the selected population, and consequently on the conclusions that can be drawn from the data, emphasizing the importance of defining the characteristics of the target population before the study in order to produce relevant results.

First hospitalization for heart failure in France in 2009: Patient characteristics and 30-day follow-up

BACKGROUNDnThe incidence of heart failure (HF) is stable in industrialized countries, but its prevalence continues to increase, especially due to the ageing of the population, and mortality remains high.nnnOBJECTIVEnTo estimate the incidence in France and describe the management and short-term outcome of patients hospitalized for HF for the first time.nnnMETHODnThe study population comprised French national health insurance general scheme beneficiaries (77% of the French population) hospitalized in 2009 with a principal diagnosis of HF after exclusion of those hospitalized for HF between 2006 and 2008 or with a chronic disease status for HF. Data were collected from the national health insurance information system (SNIIRAM).nnnRESULTSnA total of 69,958 patients (mean age 78 years; 48% men) were included. The incidence of first hospitalization for HF was 0.14% (≥ 55 years, 0.5%; ≥ 90 years, 3.1%). Compared with controls without HF, patients more frequently presented cardiovascular or other co-morbidities. The hospital mortality rate was 6.4% and the mortality rate during the 30 days after discharge was 4.4% (3.4% without readmission). Among 30-day survivors, all-cause and HF 30-day readmission rates were 18% (< 70 years, 22%; ≥ 90 years, 13%) and 5%, respectively. Reimbursements among 30-day survivors comprised at least a beta-blocker in 54% of cases, diuretics in 85%, angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) in 67%, a diuretic and ACEI/ARB combination in 23% and a beta-blocker, ACEI/ARB and diuretic combination in 37%.nnnCONCLUSIONnPatients admitted for HF presented high rates of co-morbidity, readmission and death at 30 days, and there remains room for improvement in their drug treatments; these findings indicate the need for improvement in return-home and therapeutic education programmes.

Frequency of cardiovascular diseases and risk factors treated in France according to social deprivation and residence in an overseas territory

BACKGROUNDnThe frequencies of treated cardiovascular disease (CVD) and their associated risk factors (CVRF) may vary according to socioeconomic and territorial characteristics.nnnMETHODSnThese frequencies have been described for 48million policyholders of the French general health insurance scheme, according to a metropolitan geographical deprivation index in five quintiles (from the least to the most deprived: Q1 to Q5), the existence of universal complementary health cover (CMUC) in individuals under the age of 60, and residence in a French overseas territory (FOT). The information system (SNIIRAM) was used to identify CVDs and anti-diabetic, anti-hypertensive or lipid-lowering treatments by three reimbursements in 2010.nnnRESULTSnAfter age- and sex-specific adjustment, the inhabitants of the most deprived areas more often suffered from distal arterial disease (Q5/Q1=1.5), coronary artery disease (1.2) and cerebral vascular accident (1.1), as did the CMUC beneficiaries compared to non-beneficiaries (ratios of 1.7, 1.3 and 1.5), and the FOT residents in comparison to the most deprived metropolitan quintile (Q1), with the exception of coronary artery disease (1.2, 0.6 and 1.2). Inhabitants of the most deprived areas more often received anti-diabetic and anti-hypertensive treatment (Q5/Q1=1.4 and 1.2), as did the people on the CMUC (2.0 and 1.2) and the FOT inhabitants (FOT/Q1=2.4 and 1.3). These ratios were of 1.1, 1.0 and 0.8 for lipid-lowering drugs.nnnCONCLUSIONnThese results pinpoint populations for which specific preventative initiatives could be supported. While health care service utilisation is facilitated (CMUC), it is probably not yet effective enough in view of the persistent increased cardiovascular risk.

Current challenges in providing bariatric surgery in France: A nationwide study.

Abstract Bariatric surgery is a well-accepted procedure for severe and massive obesity management. We aimed to determine trends, geographical variations, and factors influencing bariatric surgery and the choice of procedure in France in a large observational study. The Health Insurance Fund for Salaried Workers (Caisse National Assurance Maladie Travailleurs Salariés) covers about 86% of the French population. The Système National d’Information Inter-régimes de l’Assurance Maladie database contains individualized and anonymized patient data on all reimbursements for healthcare expenditure. All types of primary bariatric procedures (Roux-en-Y gastric bypass [RYGB] or omega loop, adjustable gastric banding [AGB], or longitudinal sleeve gastrectomy [LSG]) performed during 2011 to 2013 were systematically recorded. Surgical techniques performed by region of residence and age-range relative risks with 95% confidence intervals of undergoing LSG or RYGB versus AGB were computed. In 2013, LSG was performed more frequently than RYGB and AGB (57% vs 31% and 13%, respectively). A total of 41,648 patients underwent a bariatric procedure; they were predominantly female (82%) with a mean (±standard deviation) age of 40 (±12) years and a body mass index ≥40u200akg/m2 for 68% of them. A total of 114 procedures were performed in patients younger than 18 years and 2381 procedures were performed in patients aged 60 years and older. Beneficiaries of the French universal health insurance coverage for low-income patients were more likely to undergo surgery than the general population. Large nationwide variations were observed in the type choice of bariatric surgical procedures. Significant positive predictors for undergoing RYGB compared to those for undergoing AGB were as follows: referral to a center performing a large number of surgeries or to a public hospital, older age, female gender, body mass index ≥50u200akg/m2, and treatment for obstructive sleep apnea syndrome, diabetes, or depression. Universal health insurance coverage for low-income patients was inversely correlated with the probability of RYGB. Differences in access to surgery have been observed in terms of the patients profile, geographical variations, and predictors of types of procedures. Several challenges must be met when organizing the medical care of this growing number of patients, when delivering surgery through qualified centers while assuring the quality of long-term follow-up for all patients.

Antihypertensive, antidiabetic and lipid-lowering treatment frequencies in France in 2010

BACKGROUNDnThe frequencies of treatment for cardiovascular risk factors are poorly documented in large populations, particularly according to the presence or absence of cardiovascular disease (CVD).nnnAIMSnTo assess frequencies of reimbursements for antihypertensive, lipid-lowering and antidiabetic medications in France among national health insurance beneficiaries in 2010 and their associations according to age, sex, French regions, level deprivation and the presence of certain CVD.nnnMETHODSnTreatment frequencies were calculated among the beneficiaries (58xa0million people) on the basis of reimbursements for three specific categories of medicinal products in 2010. The presence of CVD was defined by a diagnosis associated with chronic disease status and hospital stays in 2010.nnnRESULTSnAmong people aged greater or equal to 20years, treatment frequencies were 22% (men 20% vs. women 23%) for antihypertensives, 15% (14% vs. 16%) for lipid-lowering agents and 6% (6% vs. 5%) for antidiabetic medications. These frequencies were, respectively, 33%, 23% and 8% in patients aged greater or equal to 40years and 55%, 38% and 14% in patients aged greater or equal to 60 years. The frequency of at least one treatment for at least one of the three risk factors was 41% in patients aged greater or equal to 40 years and 66% in patients aged greater or equal to 60 years. Among patients aged greater or equal to 20 years, 22% were treated for at least one risk factor in the absence of CVD and 3% were treated for at least one risk factor in the presence of CVD. Regional differences were observed, with higher frequencies of antihypertensive and antidiabetic use in the North, North-East and Overseas regions. Treatment frequencies increased with level of deprivation, especially for antidiabetics.nnnCONCLUSIONnThis national study more clearly defines treatment frequencies and the populations and regions with the highest treatment frequencies.

Prostate cancer outcomes in France: treatments, adverse effects and two-year mortality

BackgroundThis very large population-based study investigated outcomes after a diagnosis of prostate cancer (PCa) in terms of mortality rates, treatments and adverse effects.MethodsAmong the 11 million men aged 40xa0years and over covered by the general national health insurance scheme, those with newly managed PCa in 2009 were followed for two years based on data from the national health insurance information system (SNIIRAM). Patients were identified using hospitalisation diagnoses and specific refunds related to PCa and PCa treatments. Adverse effects of PCa treatments were identified by using hospital diagnoses, specific procedures and drug refunds.ResultsThe age-standardised two-year all-cause mortality rate among the 43,460 men included in the study was 8.4%, twice that of all men aged 40xa0years and over. Among the 36,734 two-year survivors, 38% had undergone prostatectomy, 36% had been treated by hormone therapy, 29% by radiotherapy, 3% by brachytherapy and 20% were not treated. The frequency of treatment-related adverse effects varied according to age and type of treatment. Among men between 50 and 69xa0years of age treated by prostatectomy alone, 61% were treated for erectile dysfunction and 24% were treated for urinary disorders. The frequency of treatment for these disorders decreased during the second year compared to the first year (erectile dysfunction: 41% vs 53%, urinary disorders: 9% vs 20%). The frequencies of these treatments among men treated by external beam radiotherapy alone were 7% and 14%, respectively. Among men between 50 and 69xa0years with treated PCa, 46% received treatments for erectile dysfunction and 22% for urinary disorders. For controls without PCa but treated surgically for benign prostatic hyperplasia, these frequencies were 1.5% and 6.0%, respectively.ConclusionsWe report high survival rates two years after a diagnosis of PCa, but a high frequency of PCa treatment-related adverse effects. These frequencies remain underestimated, as they are based on treatments for erectile dysfunction and urinary disorders and do not reflect all functional outcomes. These results should help urologists and general practitioners to inform their patients about outcomes at the time of screening and diagnosis, and especially about potential treatment-related adverse effects.

Prevalence and economic burden of cardiovascular diseases in France in 2013 according to the national health insurance scheme database

BACKGROUNDnCardiovascular diseases (CVDs) constitute the second leading cause of death in France. The Système national dinformation interrégimes de lassurance maladie (SNIIRAM; national health insurance information system) can be used to estimate the national medical and economic burden of CVDs.nnnOBJECTIVESnTo describe the rates, characteristics and expenditure of people reimbursed for CVDs in 2013.nnnMETHODSnAmong 57 million general health scheme beneficiaries (86% of the French population), people managed for CVDs were identified using algorithms based on hospital diagnoses either during the current year (acute phase) or over the previous 5 years (chronic phase) and long-term diseases. The reimbursed costs attributable to CVDs were estimated.nnnRESULTSnA total of 3.5 million people (mean age, 71 years; 42% women) were reimbursed by the general health scheme for CVDs (standardized rate, 6.5%; coronary heart disease, 2.7%; arrhythmias/conduction disorders, 2.1%; stroke, 1.1%; heart failure, 1.1%). These frequencies increased with age and social deprivation, and were higher in Northern and Eastern France and Réunion Island. The total sum reimbursed by all schemes for CVDs was €xa015.1 billion (50% for hospital care and 43% for outpatient care [including 15% for drugs and 12% for nurses/physiotherapists]); coronary heart disease accounted for €xa04 billion, stroke for €xa03.5 billion and heart failure for €xa02.5 billion (i.e. 10% of the total expenditure reimbursed by all national health insurance schemes for all conditions).nnnCONCLUSIONnCVDs constitute the leading group in terms of numbers of patients reimbursed and total reimbursed expenditure, despite a probable underestimation of both numbers and expenditure.

Estimation of breast, prostate, and colorectal cancer incidence using a French administrative database (general sample of health insurance beneficiaries).

AIMnThe aim of this study was to compare incidence of breast, prostate, and colorectal cancer incidence estimated from a French administrative database with the incidences estimated from the cancer registry data.nnnMATERIALS AND METHODSnA cohort of 426,410 people included in the general sample of health insurance beneficiaries (EGB) database as of January 1, 2007, was constituted. Several algorithms were developed to estimate cancer incidence between 2008 and 2012 using principal diagnosis (PD) of hospital discharge data (medical information systems program [PMSI]) and/or long-term disease (LTD) and together with a procedure necessary for histological diagnosis and indicating initial disease management. The incidence rates obtained were compared with those from the registry data using the standardized incidence ratio (SIR).nnnRESULTSnThe algorithm taking into account LTD and PD in the PMSI and the mandatory presence of a marker procedure provided estimates close to those from the registry data for breast cancer (SIR: 1.12 [1.07-1.18]) and colorectal cancer (SIR: 0.94 [0.88-1.02] in men and SIR: 0.93 [0.86-1.01] in women). For prostate cancer, taking into account specific procedures and drugs in addition to LTD and PD in the PMSI enhanced the estimation of incidence (SIR: 1.03 [0.98-1.08]).nnnCONCLUSIONnThe PMSI together with reimbursement data (LTD, procedures, drugs) provided estimates of breast, prostate, and colorectal cancer incidence, at a national level, comparable to those from the cancer registry data.

Cohort of one million patients initiating antidepressant treatment in France: 12-month follow-up

Previous studies have shown that the recommended minimum 6‐month period for antidepressant treatment is actually observed for only a minority of patients. The objectives of this study were to characterise patients with newly prescribed antidepressant treatment in France and identify factors possibly associated with insufficient duration of treatment or the occurrence of certain events such as sick leave, hospitalisations and suicide attempts.
