RESUMEN
AIM: To assess persistence with subcutaneous (SC) tumour necrosis factor (TNF) inhibitors as well as the impact of persistence on healthcare resource utilization (HCRU) and costs in patients with chronic inflammatory joint diseases. METHODS: In this cohort study using population-based French claims data (from 2011 to 2014), we measured persistence with SC TNF inhibitors within 12 months (M0-12) following treatment initiation in treatment-naïve and treatment-experienced users (divided into three cohorts: rheumatoid arthritis [RA], ankylosing spondylitis [AS] and psoriatic arthritis [PsA]). Persistent patients were propensity score matched to nonpersistent patients at M12. The impact of persistence status on HCRU and costs was assessed during M12-24. RESULTS: Of treatment-naïve (n = 3,804) and treatment-experienced (n = 2,279) users, only 56.1% and 46.8% were persistent at M12, respectively. Nonpersistent patients had more outpatient visits, computerized tomography scans, spine or joint magnetic resonance imaging procedures and disease-related hospitalizations, while persistent patients had more rheumatologist visits. Nonpersistent patients had lower drug costs but higher nondrug-related healthcare and hospitalization costs than persistent patients. In AS and PsA, overall healthcare costs were similar in persistent and nonpersistent patients. In RA, overall healthcare costs were lower in persistent patients (15,753 vs 17,590 in treatment-naïve and 17,622 vs 21,177 in treatment-experienced). CONCLUSION: Persistence with SC TNF inhibitors within first 12 months following treatment initiation was low in both treatment-naïve and treatment-experienced patients. Differences were observed in distribution of costs between persistent and nonpersistent patients, showing that nonpersistence with SC TNF inhibitors can lead to increased HCRU and higher costs.

BACKGROUND: To estimate the cost-effectiveness (CE) of etonogestrel implants compared to other long-term and short-term reversible contraceptive methods available in France. RESEARCH DESIGN AND METHODS: A 6-year Markov model compared effectiveness between the implant and six other contraceptive methods in sexually active, not-pregnancy-seeking French females of reproductive age. Contraception efficacy, switch rates and outcomes were based on French current medical practice. Incremental CE ratios (ICERs) were calculated as incremental cost per unintended pregnancy (UP) avoided. Efficiency frontier was plotted to identify cost-effective methods. Uncertainty was explored through sensitivity analyses. RESULTS: The implant was on the efficiency frontier along with combined oral contraceptive pill (COC) and copper IUD. Implant avoids between 0.75% and 3.53% additional UP per person-year compared to copper IUD and second generation COC, respectively, with an ICER of 2,221 per UP avoided compared to copper IUD. For the 240,000 French women currently using the implant, up to 8,475 UPs and up to 1,992 abortions may be prevented annually. CONCLUSION: With more unintended pregnancies avoided and comparable costs to copper IUD, the implant is a cost-effective option among long-term and short-term reversible contraceptive methods.

OBJECTIVE: Recipients of allogeneic hematopoietic stem cell transplantation (allo-HCT) with positive cytomegalovirus (CMV) serology are at increased risk of morbidity and mortality. The primary objective of this study was to assess the association between treated CMV infection and overall mortality within 1 year after allo-HCT in adult CMV-seropositive Recipients (R+). Secondary objectives included overall 5-year mortality after allo-HCT, risk factors for treated CMV infection, associations between treated CMV infection and allo-HCT complications and medical costs. METHODS: A multicenter retrospective cohort study was conducted in adult CMV-seropositive recipients (R+) who underwent to allo-HCT between 1st January 2010 and 31st December 2014. RESULTS: Five hundred seventy two CMV-seropositive patients (mean age, 50.2 years) undergoing allo-HCT between 2010 and 2014 were included; 55.9% of donors were CMV seropositive. CMV infection treated with antiviral therapy was reported in 227 patients (39.7%) after transplantation. One-year overall mortality was significantly increased in patients with treated CMV infections (hazard ratio, 1.86; 95% CI, 1.16-3.00; P = .011). Mean medical costs during the first post-HCT year were higher in patients with CMV infection (46 853 vs 31 318; P < .0001). CONCLUSION: In this large cohort of CMV-seropositive patients undergoing allo-HCT, treated CMV infection was significantly associated with an increased 1-year risk of overall mortality, with increased length of stay and with hospitalization cost. The burden of CMV disease in allo-HCT could be reduced in the future by appropriate prophylactic strategies.
RESUMEN
OBJECTIVE: In June 2022, French health authorities issued a universal recommendation for routine administration and reimbursement of rotavirus vaccines in infants. Given this recent recommendation by French health authorities, we sought to understand the public health impact of a universal rotavirus vaccination strategy compared with no vaccination. MATERIALS AND METHODS: A deterministic, age-structured, nonlinear dynamic transmission model, accounting for herd immunity, was developed. We considered 3 vaccination coverage scenarios: high (95%), medium (75%) and low (55%). Model parameter values were based on published modeling and epidemiological literature. Model outcomes included rotavirus gastroenteritis (RVGE) cases and healthcare resource utilization due to RVGE (hospitalizations, general practitioner or emergency department visits), as well as the number needed to vaccinate to prevent 1 RVGE case (mild or severe) and 1 RVGE-related hospitalization. Model calibration and analyses were conducted using Mathematica 11.3. RESULTS: Over 5 years following implementation, RVGE cases for children under 5 years are estimated to be reduced by 84% under a high vaccination coverage scenario, by 72% under a medium vaccination coverage scenario and by 47% under a low vaccination coverage scenario. Across all scenarios, the number needed to vaccinate to avert 1 RVGE case and hospitalization varied between 1.86-2.04 and 24.15-27.44, respectively. CONCLUSIONS: Rotavirus vaccination with high vaccination coverage in France is expected to substantially reduce the number of RVGE cases and associated healthcare resource utilization.
RESUMEN
BACKGROUND: Riociguat is the first approved treatment for inoperable and persistent/recurrent post-surgery chronic thromboembolic pulmonary hypertension (CTEPH). The RetrospectIve Adempas® stuDy (RiAD) aimed to describe the real-world utilization of riociguat in France. METHODS: In this retrospective multicentric study in patients initiating riociguat, dosing regimen, co-treatments and clinical characteristics were collected over a 2-year follow-up period. RESULTS: A total of 173 patients (mean age, 71.4 years; female, 63.0%; NYHA II-III, 80.3%) were included from January 2015 to December 2016 in 18 centers. All patients were diagnosed with CTEPH (75.7% inoperable and 20.8% with persistent/recurrent pulmonary hypertension [pH] after surgery) with mean (SD) right atrial pressure 7.6 (4.2) mmHg, mean pulmonary artery pressure 43.0 (11.4) mmHg and mean cardiac output 4.1 (1.1) L/min. Before riociguat initiation, 32.4% of patients previously received at least one pH-specific therapy. At initiation, 93.1% of patients were receiving anticoagulants and 83.2% were not receiving pH-specific co-treatments. Riociguat was initiated at 1 mg three times daily (t.i.d.) in 85.5% of patients and 82.1% were receiving 2.5 mg dose t.i.d. at 24 months. The maximal daily dose of 7.5 mg was never exceeded. At 24 months, the estimated rate of patients still taking riociguat was 78.8% with an estimated mean (SD) time on treatment of 20.1 (0.5) months per patient. No new safety signals were recorded. CONCLUSIONS: The results of this real-world study show that riociguat is used in France in accordance with its therapeutic indication in patients with inoperable or persistent/recurrent post-operative CTEPH and confirm its long-term safety.

A European observational cross-sectional study, ESPERA, was conducted in France and Spain in 2010. A random sample of neurologists, including specialists in epilepsy, prospectively enrolled adult patients treated for focal epilepsy with at least two antiepileptic drugs (AEDs) in combination. Investigators were asked to classify AED responsiveness of each enrolled patient according to the new 2009 ILAE criteria. These classifications were then reviewed by three experts. Potential factors of misclassification were then analyzed in order to evaluate the applicability of the new ILAE criteria for antiepileptic drug resistance in current clinical practice. Because of their complexity, use of the new ILAE criteria needs to be supported by relevant information and training to be adequately applied by neurologists in everyday practice.

Considering their novelty and cost, post-marketing evaluation is highly relevant for new anticancer drugs. Identify and characterize available and potentially useful databases for post-marketing evaluation of these specific drugs is necessary. A review was conducted to identify available and accessible databases to study the post-marketing evaluation of drugs in real-life care setting. Databases identified have been classified into medico-administrative databases, medical record databases, and databases resulting from ad hoc collections. Taking as examples databases available in France, each type was described as well as its strengths and limits for a potential use in the oncology field. Record linkage of medico-administrative databases could cover almost the whole population and is now used to evaluate anticancer drugs (e.g., Système National des Données de Santé). Large medical record databases are still lacking, but efforts are currently made to give access to hospital data warehouses for research purposes. Finally, databases resulting from ad hoc collections are also available for some cancer localizations and allow to obtain highly valuable clinical and biological data. A range of important and valuable databases exist but, individually, none is enough to answer to all questions from health authorities, healthcare professionals, and patients. In order to obtain a complete overview on utilization, associated health outcomes and costs of these drugs, it seems necessary to better interlink available databases.

INTRODUCTION: Since 2014, Balloon Pulmonary Angioplasty (BPA) has become an emerging and complementary strategy for chronic thromboembolic hypertension (CTEPH) patients who are not suitable for pulmonary endarterectomy (PEA) or who have recurrent symptoms after the PEA procedure. OBJECTIVE: To assess the hospital cost of BPA sessions and management in CTEPH patients. METHODS: An observational retrospective cohort study of CTEPH-adults hospitalized for a BPA between January 1st, 2014 and June 30th, 2016 was conducted in the 2 centres performing BPA in France (Paris Sud and Grenoble) using the French national hospital discharge database (PMSI-MCO). Patients were followed until 6 months or death, whichever occurred first. Follow-up stays were classified as stays with BPA sessions, for BPA management or for CTEPH management based on a pre-defined algorithm and a medical review using type of diagnosis (ICD-10), delay from last BPA procedure stay and length of stay. Hospital costs (including medical transports) were estimated from National Health Insurance perspective using published official French tariffs from 2014 to 2016 and expressed in 2017 Euros. RESULTS: A total of 191 patients were analysed; mainly male (53%), with a mean age of 64,3 years. The first BPA session was performed 1.1 years in median (IQR 0.3-2.92) after the first PH hospitalisation. A mean of 3 stays with BPA sessions per patient were reported with a mean length of stay of 8 days for the first stay and 6 days for successive stays. The total hospital cost attributable to BPA was 4,057,825 corresponding to 8,764±3,435 per stay and 21,245±12,843 per patient. Results were sensitive to age classes, density of commune of residence and some comorbidities. CONCLUSIONS: The study generated robust real-world data to assess the hospital cost of BPA sessions and management in CTEPH patients within its first years of implementation in France.

OBJECTIVES: In France, 9-valent HPV vaccination is recommended routinely for 11-14-years-old girls and as catch-up for 15-19-years-old girls. Recently, recommendation for gender-neutral vaccination (GNV) has been approved. The objectives of the study were to assess the public health impact and cost-effectiveness of a 9-valent GNV compared with girls-only vaccination program (GOV). METHODS: A published HPV disease transmission dynamic model accounting for herd protection effects with a 100-year time horizon was adapted and calibrated to French data. Epidemiological and economic outcomes included disease cases averted and quality-adjusted life years (QALY). Costs and incremental cost-effectiveness ratio (ICER) were measured in 2018 Euros (). A coverage rate of 26.2% among girls and boys was assumed for the GNV program based on the current female coverage rate in France. The base case included genital warts, cervical, vulvar, vaginal, and anal cancers. Scenario analyses included all HPV-related diseases and considered higher vaccination coverage rate (60%). Deterministic sensitivity analyses on key inputs were performed. RESULTS: Over 100 years, GNV resulted in an additional reduction of 9,519 and 3,037 cervical cancer cases and deaths; 6,901 and 1,166 additional anal cancer cases and deaths; and a reduction of additional 1,284,077 genital warts compared with current GOV and an ICER of 24,763/QALY. When including all HPV-related diseases, the ICER was 15,184/QALY. At a higher coverage rate (60%), GNV would prevent 17,430 and 4,334 additional anogenital cancer cases and deaths and over two million genital warts compared with GOV with an ICER of 40,401/QALY. Results were sensitive to a higher discount rate (6% versus 4%) and a shorter duration of protection (20 years versus lifetime). CONCLUSIONS: In France, GNV has a significant impact in terms of public health benefits and may be considered cost-effective compared with GOV at low and high coverage rates.

OBJECTIVES: To describe the real-world clinical use of ceftolozane/tazobactam (C/T) and associated outcomes in France. PATIENTS AND METHODS: Multicenter, prospective cohort study conducted in 22 hospitals. All adult patients who received at least one dose of C/T were asked to participate (2018-2019). Patients were treated according to standard hospital practice and followed up until C/T stop. RESULTS: At the time of the analysis, 84 patients were evaluated. The median age was 64.8 years, and 67.9% (57/84) of patients were males. Fifty-seven patients (57/82, 69.5%) had one or more risk factors for multidrug-resistant (MDR) infections (missing MDR risk factor data for two patients). Most patients were critically ill and had several comorbidities. A majority (59/84, 70.2%) of patients had nosocomial infections. Half of all patients (n=42) had a diagnosis of pneumonia, of which 69% (29/42) were hospital acquired. Overall, 90.5% (76/84) of patients had MDR bacteria. Pseudomonas aeruginosa was the most frequently isolated bacterium (71/80, 88.8%), including 93% (80/86) of C/T-susceptible strains. C/T was prescribed as the first-line treatment to 29.8% (25/84) of patients. A concomitant antibiotic treatment was prescribed to 48.8% (41/84) of patients, of whom 65.9% (27/41) were prescribed concomitant antibiotics at the same time as C/T initiation. Empirical C/T prescription was microbiologically appropriate in 11/16 patients after susceptibility testing. Most patients (44/72, 61.1%) were cured and four (4/72, 5.6%) deaths were reported. CONCLUSIONS: The results showed that C/T was most frequently prescribed for documented cases of P. aeruginosa infections. Most outcomes were positive, including among pneumonia patients.

Aim: To describe real-world pembrolizumab administration and outcomes for advanced melanoma in France. Materials & methods: Using the MelBase longitudinal database, this multicenter historical-prospective study examined treatment and outcomes of patients with nonuveal, unresectable stage III/IV melanoma initiating pembrolizumab from April 2016 to September 2017, with follow-up to September 2019. Kaplan-Meier time-to-event analyses were conducted. Results: Of 223 patients (median age 67; 51% men), 134 (60%), 36 (16%) and 53 (24%) initiated pembrolizumab in first-, second- and third-line, respectively. Median overall survival (months) was 32.6 (95% CI: 20.3-not reached [NR]), 14.4 (8.6-NR) and 9.3 (6.4-NR), respectively. Best real-world tumor response of complete or partial response was recorded for 49, 39 and 26% of patients, respectively. Conclusion: Study results support benefits of pembrolizumab therapy for advanced melanoma.

BACKGROUND: The French Cancer Plan 2014-2019 had a target of 60% HPV vaccine coverage. The PAPILLON study investigated the annual age-specific vaccination initiation rates and cumulative partial and complete vaccination rates in France from 2017 to 2022. It also identified the factors associated with vaccination in different age groups and those associated with the type of completion of the vaccination scheme (partial vs full vaccination). METHODS: For this publication, all females recorded in the French National Claims database who initiated HPV vaccination between 1 July 2007 and 31 December 2018 and were aged between 11 and 19 years at initiation were included. Annual HPV vaccination initiation rates were estimated in 11- to 14-year-old (target population) and 15- to 19-year-old females (catch-up). Cumulative vaccine coverage rates (VCRs) were estimated among those who were 15, 16, 20 and 21 years old. Partial vaccination was defined by dispensing of at least one dose of HPV vaccine by the pharmacy, while full vaccination was defined by two or three doses dispensed by a pharmacy over an 18-month period, according to current French recommendations based on the age at vaccination initiation. RESULTS: Among the 465,629 females who initiated HPV vaccination in 2017 or 2018, the initiation rate increased from 7.7 to 11.1% in 11- to 14-year-old girls and from 4.5 to 6.5% in 15- to 19-year-old females. In 2017 and 2018, the cumulative VCRs for partial vaccination by age 15 were 28.2% and 32.8%, respectively, while by age 20, they were 41.6% and 38.8%. The cumulative VCRs for full vaccination were 15.6% and 18.6% by age 16, while they were 25.9 and 23.6% by age 20. HPV vaccination initiation and completion were strongly associated with the use of health services. CONCLUSION: Overall, the HPV VCR substantively increased between 2017 and 2018, which is positive evidence of the resumption of vaccination. Updates in 2022 should confirm these results.

INTRODUCTION: Diabetes is a growing epidemic that imposes a substantial economic burden on healthcare systems. This study aimed to evaluate the cost of managing type 2 diabetes (T2D) with dipeptidyl peptidase 4 inhibitors (DPP4Is) using real-world data. METHOD: This longitudinal study used data from the French EGB (Echantillon Généraliste des Bénéficiaires) database. The annual average direct healthcare cost of treating patients with T2D was calculated 3 years prior and 3 years after initiation of DPP4I therapy. Actual total ambulatory and hospital care expenditure for the 3 years after DPP4I initiation was compared to projected costs. The distribution of costs across all care modalities was assessed over the 6-year period. RESULTS: Ambulatory and hospital care expenditure data for 919 patients with T2D starting DPP4I therapy alone or in combination in 2013 were analyzed. A total of 526 patients (57.2%) were still being treated with DPP4I 3 years after DPP4I initiation. Regardless of the treatment regimen, the ambulatory and hospital care costs increased above projected costs in the first year following DPP4I initiation, and then declined during the second and third years to levels in line with or below projected values for patients using DPP4Is as an add-on therapy. The increase in total expenditure in the first year following DPP4I initiation and the subsequent decline in costs in the second and third years were both associated with general trends in consumption across all aspects of patient care. CONCLUSION: Despite an initial increase in healthcare expenditure, concomitant with reevaluation of patient care, this study showed that initiation of DPP4Is as an add-on therapy in French patients with T2D was associated with care expenditure that was in line or below predicted values within the 3 years following treatment initiation. Additional studies are required to evaluate the economic impact of the long-term treatment benefits.
RESUMEN
OBJECTIVES: To determine whether changes in ultrasonography (US) features of monosodium urate crystal deposition is associated with the number of gouty flares after stopping gout flare prophylaxis. METHODS: We performed a 1-year multicentre prospective study including patients with proven gout and US features of gout. The first phase of the study was a 6-month US follow-up after starting urate-lowering therapy (ULT) with gout flare prophylaxis. After 6 months of ULT, gout flare prophylaxis was stopped, followed by a clinical follow-up (M6 to 12) and ULT was maintained. Outcomes were the proportion of relapsing patients between M6 and M12 according to changes of US features of gout and determining a threshold decrease in tophus size according to the probability of relapse. RESULTS: We included 79 gouty patients (mean [±SD] age 61.8±14 years, 91% males, median disease duration 4 [IQR 1.5; 10] years). Among the 49 completers at M12, 23 (47%) experienced relapse. Decrease in tophus size≥50% at M6 was more frequent without than with relapse (54% vs. 26%, P=0.049). On ROC curve analysis, a threshold decrease of 50.8% in tophus size had the best sensitivity/specificity ratio to predict relapse. Probability of relapse was increased for patients with a decrease in tophus size <50% between M0 and M6 (OR 3.35 [95% confidence interval 0.98; 11.44]). CONCLUSION: A high reduction in US tophus size is associated with low probability of relapse after stopping gout prophylaxis. US follow-up may be useful for managing ULT and gout flare prophylaxis.

INTRODUCTION: In the KEYNOTE-024 trial, pembrolizumab demonstrated significant improvements in progression-free survival (PFS) and overall survival (OS) versus Standard-of-Care (SoC) platinum-based doublets for first-line treatment of PD-L1 -positive (≥50%) metastatic Non-Small-Cell Lung Cancer (NSCLC) patients with no EGFR mutations or ALK translocations. This study aims to assess the cost-effectiveness of pembrolizumab versus SoC platinum-based chemotherapy from the French healthcare system perspective. METHODS: A three-state partitioned-survival model was adapted to project outcomes and costs of squamous and non-squamous NSCLC patients respectively, over a 10-year time horizon. Clinical and utility data were collected from the trial. A network meta-analysis was performed to consider platinum-based triplets also used for non-squamous NSCLC. Direct medical costs were considered based on ressources identified from the trial and literature. Costs and outcomes were discounted at 4% per year. Incremental cost-effectiveness ratios (ICERs) were calculated as cost per Life Year (LY) and cost per Quality-Adjusted Life Year (QALY). Sensitivity and scenario analyses were performed to assess the robustness of results. RESULTS: For squamous NSCLC, pembrolizumab was projected to increase life expectancy of patients by 0.93 LY (11 months), and 0.74 QALY (9 months) for an incremental cost of 62,032 compared with platinum-based doublets. The ICER of pembrolizumab versus platinum-based doublets was 66,825/LY and 84,097/QALY. For non-squamous NSCLC, pembrolizumab was projected to increase life expectancy of patients by 0.85-1.32 LYs (10.2-15.8 months) and 0.64-1.02 QALYs (7.7-12.2 months) for an incremental cost varying from -14,947-+47,064 depending on the specific comparator. The ICER of pembrolizumab versus platinum-based chemotherapy with paclitaxel plus bevacizumab was 62,846/LY and 78,729/QALY; regimens including pemetrexed were dominated. Results were most sensitive to extrapolations of survival outcomes and assumptions for continued effectiveness and treatment duration of pembrolizumab. CONCLUSIONS: Pembrolizumab appears cost-effective versus SoC chemotherapy for first-line treatment of PD-L1-positive (50%) metastatic NSCLC patients in France, assuming willingness-to-pay under 100,000/QALY (OECD threshold in the discussion section).

OBJECTIVE: To assess the effectiveness and costs associated with contraceptive methods based on real-world data in France. STUDY DESIGN: A cross-sectional cohort study based on data from a representative sample of the French National Healthcare Insurance Database (Echantillon Généralistes des Bénéficiaires (EGB)) was performed between January 1st 2006 and December 31st 2012. Women aged 15 years or older and users of at least one reimbursed contraceptive method between January 1st 2012 and December 31st 2012 were selected. The outcome of interest was unintended pregnancy, defined as pregnancies occurring after at least one month since the dispensation of a contraceptive method. The mean annual costs of contraceptive methods (in 2012 Euros) were collected in the database from a health system perspective. Costs were expressed for the first year of use, considering the next years of use and taking into account or not the cost of unplanned pregnancies. RESULTS: A population of 48,090 women representative of the 4,664,730 French women with a reimbursed contraceptive method was identified in the EGB in 2012: 68.6% used at least one reimbursed oral contraception (OC), 30.2% used at least one intrauterine devices (IUD) (LGN-IUS 52 mg, 17.6%; copper, 13.1%) and 5.1% used at least one etonogestrel implant. Unplanned pregnancies rates ranged from 0.6% with LNG-IUS 52 mg and 0.8% with the etonogestrel implant to 4.8% with 1st and 2nd generation combined OCs. The mean annual costs of contraception for the first year of use ranged from 145 for 1st-2nd generation combined oral contraceptions (COCs) to 308 for LNG-IUS 52 mg taking into account the next years of use, the etonogestrel implant was associated with the lowest mean annual cost (88). When costs of unplanned pregnancies were taken into account, the mean annual cost of contraception for the first year of use was lower for progestin-only OC (251) and copper IUD (257) compared to etonogestrel implant (300) and LNG-IUS 52 mg(323). CONCLUSION: This real-world study suggests that Long-acting reversible contraceptives (LARCs) (i.e. implant and IUDs) should be considered for a broader use to prevent unplanned pregnancies and related abortions in France both from a public health and economic perspective.

OBJECTIVE: To assess the cost-effectiveness of the elbasvir/grazoprevir (EBR/GZR) regimen in patients with genotype 1 chronic hepatitis C virus (HCV) infection with severe and end-stage renal disease compared to no treatment. DESIGN: This study uses a health economic model to estimate the cost-effectiveness of treating previously untreated and treatment experienced chronic hepatitis C patients who have severe and end stage renal disease with the elbasvir-grazoprevir regimen versus no treatment in the French context. The lifetime homogeneous markovian model comprises of forty combined health states including hepatitis C virus and chronic kidney disease. The model parameters were from a multicentre randomized controlled trial, ANRS CO22 HEPATHER French cohort and literature. 1000 Monte Carlo simulations of patient health states for each treatment strategy are used for probabilistic sensitivity analysis and 95% confidence intervals calculations. The results were expressed in cost per quality-adjusted life year (QALY) gained. PATIENTS: The mean age of patients in the HEPATHER French cohort was 59.6 years and 56% of them were men. 22.3% of patients had a F0 fibrosis stage (no fibrosis), 24.1% a F1 stage (portal fibrosis without septa), 7.1% a F2 stage (portal fibrosis with few septa), 21.4% a F3 stage (numerous septa without fibrosis) and 25% a F4 fibrosis stage (compensated cirrhosis). Among these HCV genotype 1 patients, 30% had severe renal impairment stage 4, 33% had a severe renal insufficiency stage 5 and 37% had terminal severe renal impairment stage 5 treated by dialysis. INTERVENTION: Fixed-dose combination of direct-acting antiviral agents elbasvir and grazoprevir compared to no-treatment. RESULTS: EBR/GZR increased the number of life years (6.3 years) compared to no treatment (5.1 years) on a lifetime horizon. The total number of QALYs was higher for the new treatment because of better utility on health conditions (6.2 versus 3.7 QALYs). The incremental cost-utility ratio (ICUR) was of 15,212 per QALY gained for the base case analysis. CONCLUSIONS: This cost-utility model is an innovative approach that simultaneously looks at the disease evolution of chronic hepatitis C and chronic kidney disease. EBR/GZR without interferon and ribavirin, produced the greatest benefit in terms of life expectancy and quality-adjusted life years (QALY) in treatment-naïve or experienced patients with chronic hepatitis C genotype 1 and stage 4-5 chronic kidney disease including dialysis patients. Based on shape of the acceptability curve, EBR/GZR can be considered cost-effective at a willingness to pay of 20,000 /QALY for patients with renal insufficiency with severe and end-stage renal disease compared to no treatment.

OBJECTIVES: Our objects was to estimate the direct healthcare costs of type 2 diabetes mellitus (T2DM) in France in 2013. METHODS: Data were drawn from a random sample of ≈600,000 patients registered in the French national health insurances database, which covers 90% of the French population. An algorithm was used to select patients with T2DM. Direct healthcare costs from a collective perspective were derived from the database and compared with those from a control group to estimate the cost of diabetes and related comorbidities. Overall direct costs were also compared according to the diabetes therapies used throughout the year 2013. RESULTS: Cost analysis was available for a sample of 25,987 patients with T2DM (mean age 67.5 ± standard deviation 12.5; 53.9% male) matched with a control group of 76,406 individuals without diabetes. Overall per patient per year medical expenditures were 6506 ± 10,106 in the T2DM group as compared with 3668 ± 6954 in the control group. The cost difference between the two groups was 2838 per patient per year, mainly due to hospitalizations, medication and nursing care costs. Total per capita annual costs were lowest for patients receiving metformin monotherapy (4153 ± 6170) and highest for those receiving insulin (12,890). However, apart from patients receiving insulin, costs did not differ markedly across the different oral treatment patterns. CONCLUSION: Extrapolating these results to the whole T2DM population in France, total direct costs of diagnosed T2DM in 2013 was estimated at over 8.5 billion. This estimate highlights the substantial economic burden of this condition on society.
RESUMEN
BACKGROUND: Adverse events (AEs) related to medical treatments in non-small cell lung cancer (NSCLC) are frequent and need an appropriate costing in health economic models. Nevertheless, data on costs associated with AEs in NSCLC are scarce, particularly since the development of immunotherapy with specific immune-related AEs. OBJECTIVE: To estimate the costs of grades 3 and 4 AEs related to NSCLC treatments including immunotherapy in France. METHODS: Grades 3 and 4 AEs related to treatment and reported in at least 1% of patients in Phase III clinical trials for erlotinib, ramucirumab plus docetaxel, docetaxel, pemetrexed plus carboplatin plus bevacizumab, platinum-based chemotherapies, nivolumab and pembrolizumab were identified. When no cost evaluation was reported in literature, estimates on standard treatments and medical resource use for each AE were obtained thanks to an expert panel. Total cost per AE was calculated from a French national health insurance perspective and updated in 2017 Euros. Hospital stay costs were estimated based on public and private weighted tariffs and data from the French Medical Information System (Programme de Médicalisation des Systèmes d'Information). Costs of tests, consultations and treatments were calculated based on national reimbursement tariffs. RESULTS: Overall, costs of grades 3 and 4 AEs related to treatment ranged from 46 per event to 7,742 per year. Fourteen out of 24 AEs identified had a mean estimated cost over 2,000. The highest mean costs were related to type 1 diabetes (7,742 per year) followed by pneumonitis (5,786 per event), anemia (5,752 per event), dehydration (5,207 per event) and anorexia (4,349 per event). Costs were mostly driven by hospitalization costs. CONCLUSION: Among the AEs identified, a majority appeared to have an important economic impact, with a management cost of at least 2,000 per event mainly driven by hospitalization costs. This study may be of interest for economic evaluations of new interventions in NSCLC.
RESUMEN
BACKGROUND: Mortality and complications of acute myocardial infarction (AMI) in France have declined over the last twenty years, but still remain high. Practice guidelines recommend secondary prevention measures to reduce these. Insurance claims databases can be used to assess the management of post MI and other cardiovascular outcomes in everyday practice. METHODS: A cohort study was performed in a 1/97 representative sample of the French nationwide claims and hospitalisation database (EGB database). All adults with a documented hospitalisation for MI between 2007 and 2011 were included, and followed for three years. Data was extracted on demographics, the index admission, reimbursed medication, comorbidities, post-MI events and death. RESULTS: During the study period, 1977 individuals hospitalised for an MI were identified, with a mean (±SD) age of 63.8 (±14.3) years, 65.8% were men, 82.4% had hypertension and 37.6% hypercholesterolaemia. The mean duration of hospitalisation was seven days and 8.3% of patients died during hospitalisation. After discharge, the majority of patients received secondary prevention with statins (92.2%), anti-platelet drugs (95.6%), beta-blockers (86.0%) and angiotensin converting enzyme inhibitors (71.4%). After three years of follow-up post-discharge, cumulative mortality was 20.5% [18.4%;22.5%] and the cumulative incidence of reinfarction and stroke/TIA were 4.7% [95% CI: 3.7%;5.7%] and 4.1% [3.1%;5.0%], respectively. CONCLUSIONS: Despite high use of secondary prevention at discharge, mortality and incidence of serious cardiovascular events following MI remain high. This underscores the need to improve secondary prevention.
