Human Papillomavirus (HPV) vaccination coverage among French adolescents: A claims data study.

BACKGROUND: The French cancer control strategy 2021-2030 aims to achieve 80 % human papillomavirus (HPV) vaccination coverage. Since 2021, HPV vaccination is also recommended for boys aged 11-14 years, with a catch-up vaccination recommended for unvaccinated adolescents aged ≤19 years. The PAPILLON study used claims data to monitor the evolution of HPV Vaccination Coverage Rate (VCR) in the French population. METHODS: The annual HPV VCR was described from 2017 to 2022. Partial vaccination was defined as the dispensing of at least one dose of HPV vaccination. Full scheme vaccination was defined according to the current French recommendations as two or three doses of HPV vaccine over an 18-month period. Annual HPV vaccine initiation rates were estimated on 11-14 and 15-19-year-olds adolescents. Cumulative VCR were estimated on adolescents aged between 11 and 19 years at the time of first vaccination. RESULTS: Overall, 1,773,900 females and 592,167 males initiated HPV vaccination between 2017 and 2022. Initiations occurred between 11 and 14 years for 67.3 % of females and 62.4 % of males with a median time between the first two doses of 195 days and 190 days, respectively. In girls, the cumulative vaccination rate for the partial scheme vaccination at 15 y.o. increased from 28.1 % in 2017 to 50.9 % in 2022. Similarly, the cumulative vaccination rate for the full scheme vaccination at 16 y.o. increased from 15.5 % in 2017 to 33.8 % in 2022. In 2022, the initiation rates for males were 12.6 % at age 14 and 1.9 % at age 19. CONCLUSIONS: HPV vaccination coverage increased between 2017 and 2022 among girls targeted by the recommendation but remains insufficient. The results of this study show a tentative but promising start to vaccination in boys. This study will monitor the effects of actions taken to improve vaccination, including the extension of vaccination competencies to community pharmacists since end of 2022.

Epidemiology of myasthenia gravis in France: A retrospective claims database study (STAMINA).

BACKGROUND: The objectives of this observational study were to report the incidence and prevalence of myasthenia gravis (MG) in France, describe patients' characteristics and treatment patterns, and estimate mortality. METHODS: A historical cohort analysis was performed using the French National Health Data System (SNDS) database between 2008 and 2020. Patients with MG were identified based on ICD-10 codes during hospitalization and/or long-term disease (ALD) status, which leads to a 100% reimbursement for healthcare expenses related to MG. The study population was matched to a control group based on age, sex and region of residence. RESULTS: The overall incidence of MG was estimated at 2.5/100,000 in 2019 and the overall prevalence at 34.2/100,000. The mean age was 58.3 years for incident patients and 58.6 for prevalent patients. Among patients with MG, 57.1% were women. In the first year after identification of MG, acetylcholinesterase inhibitors were the most commonly used treatments (87.0%). Corticosteroids were delivered to 58.3% of patients, intravenous immunoglobulin to 34.4%, and azathioprine to 29.9%. Additionally, 8% of patients underwent thymectomy. The proportions of patients with exacerbations and crises were 59.7% and 13.5% respectively in the first year after MG identification. All-cause mortality was significantly higher in patients with MG compared to matched controls (HR=1.82 (95% CI [1.74;1.90], P<0.0001)). CONCLUSION: In this study, the incidence and prevalence of MG estimated in France were found to be higher than previously reported. Most exacerbations and crises occurred within the first year after MG identification. MG was associated with increased mortality compared to a control population matched on age, gender, and geographical region.

Out-of-pocket expenditures in France to manage psoriasis in adult patients: results from an observational, cross-sectional, non-comparative, multicentre study.

BACKGROUND: In 2018 in France, overall mean health-related out-of-pocket (OOP) expenditures were 214.00€/year/patient. AIM: To evaluate OOP expenditures for psoriasis patients in France. METHODOLOGY: Observational, cross-sectional, non-comparative, multicentre study in 3000 patients with clinically confirmed psoriasis who responded to a specific digital questionnaire collecting demographic and socio-economic characteristics, assessing the 3 domains (severity, psychosocial impact and past history and interventions) of the patient's Simplified Psoriasis Index (sa-SPI) and expenditures to manage psoriasis, including OOP. Multivariate linear regression was conducted to search for factors associated with higher OOP. RESULTS: In total, 2681 patients completed the questionnaire and, of those, 2562 provided clinically validated data. Overall, 60% were women; the mean age was 49.4 ± 14.8 years. 30% of the patients declared that they suffered from psoriatic arthritis. The final mean sa-SPI core was 10.86 ± 9.70. Of these 2562 patients, 243 (9.5%) had severe, 442 (17.3%) moderate and 1877 (73.3%) mild psoriasis. In addition, 932 (36.4%) patients reported facial involvement, 724 (28.25%) genital impairment and 1124 (43.8%) lesions on the limbs. Mean OOP expenditures to manage psoriasis per patient were 531.00€, 439.74€ ± 939.85€ for patients with mild, 791.06€ ± 1367.67€ with moderate and 1077.64€ ± 1680.14€ for patients with severe psoriasis. For patients with psoriasis in the genital area, the median amount of expenditures (251.17€; CI95% [138.35;363.99]) was significantly higher than that for the face (183.85€; CI95% [78.76;288.94]) or limbs (199.96€; CI95% [93.77;306.15); (P < 0.001). More than 90% of the patients had OOP expenditures for over-the-counter products (97.5%) and alternative care (92.0%), especially for emollients and/or hydrating products. CONCLUSION: In France, in 2019, OOP expenditures to manage psoriasis were on average more than twice as high as the overall mean health-related OOP expenditures estimated by the French Health Agency in 2018. These results should lead health authorities to review certain standards of healthcare reimbursement.

Costs of perennial allergic rhinitis and allergic asthma increase with severity and poor disease control.

BACKGROUND: Perennial allergic rhinitis (PAR) represents a global and public health problem, due to its prevalence, morbidity, and impact on the quality of life. PAR is frequently associated with allergic asthma (AA). Costs of PAR with or without AA are poorly documented. OBJECTIVE: Our study aimed to detail medical resource utilization (MRU) and related direct cost for PAR, with or without concomitant AA, in France. METHODS: Using Electronic Health Records (EHRs), we identified in 2010 two cohorts of PAR patients, based on General Practitioners' diagnoses and prescribing data, with and without concomitant AA. For each patient, the EHRs were linked to corresponding claims data with MRU and costs during years 2011 to 2013. Predefined subgroup analyses were performed according to severity of PAR and level of AA control. RESULTS: The median annual cost reimbursed by social security system for a patient with PAR, and no AA was 159€ in 2013. This varied from 111€ to 188€ depending on PAR severity. For patients with PAR and concomitant AA, the median annual cost varied between 266€ and 375€, and drug treatment accounted for 42-55% of the costs, depending on asthma control. CONCLUSION: This study linking diagnoses from EHRs to claims data collected valid information on PAR management, with or without concomitant AA, and on related costs. There was a clear increase in costs with severity of PAR and control of AA.

CAPECO: Cost evaluation of community acquired pneumonia managed in primary care.

BACKGROUND: Estimating the economic burden of community acquired pneumonia (CAP) managed in ambulatory setting is needed in France since no data are available. METHOD: A retrospective study (CAPECO) was conducted based on a prospective French study describing patients with suspected CAP managed in primary care (CAPA). The aim of the CAPECO study was to estimate and explain medical costs of a disease episode in CAP patients only followed in ambulatory care and in hospitalised patients. Primary endpoints were the direct medical costs, impact on productivity and costs of incident CAP over one year. Secondary endpoint was to describe predictive factors of costs, hospital admission and stay length. RESULTS: In this cohort of 886 patients, resulting in an incidence of CAP of 400 per 100,000 inhabitants per year, the mean direct medical cost of a disease episode of CAP was € 118.8 for strictly ambulatory patients with an equal weight for medical time, drugs, diagnostic procedures and tests. This direct cost was € 102.1 before admission for patients who were finally hospitalised. The mean cost of hospital admissions was € 3522.9. Main predictive factors of hospital admission and stay length were respectively a history of chronic respiratory disease and older age. Factors of direct medical cost were prescribing X-ray examination and having a positive X-ray. The impact of a disease episode on productivity was € 1980 (sd 1400) per ambulatory episode and € 5425 (sd 4760) per episode leading to hospital admission. CONCLUSION: Costs per ambulatory episode were modest but increased substantially in hospitalised patients, who were more numerous when chronic respiratory disorders were present and in the elderly. Indirect costs were significant. Deciders should thus consider both direct and indirect costs when assessing preventive interventions in the context of this disease.

Treatment maintenance duration of dual therapy with metformin and sitagliptin in type 2 diabetes: The ODYSSEE observational study.

AIM: The study compared the duration of maintenance of treatment in patients with type 2 diabetes (T2D) using dual therapy with either metformin and sitagliptin (M-Sita) or metformin and a sulphonylurea (M-SU). MATERIALS AND METHODS: This observational study included adult patients with T2D who had responded inadequately to metformin monotherapy and therefore had started de-novo treatment with Met-Sita or Met-SU within the previous eight weeks. Patient follow-up and changes to treatment were performed according to their general practitioner's usual clinical practice. The primary outcome was time to change in treatment for whatever cause. HbA1c and symptomatic hypoglycaemia were also documented. RESULTS: The median treatment duration for patients in the M-Sita group (43.2 months) was significantly longer (P < 0.0001) than in the M-SU group (20.2 months). This difference persisted after adjusting for baseline differences and confounders. A similar reduction in HbA1c was noted in both arms (-0.6%), and the incidence of hypoglycaemia prior to treatment modification was lower with M-Sita (9.7%) than with M-SU (21.0%). Adverse events potentially related to treatment were reported in 2.8% (n = 52) and 2.7% (n = 20) of patients in the M-Sita and M-SU arms, respectively. CONCLUSION: Under everyday conditions of primary diabetes care, dual therapy with M-Sita can be maintained for longer than M-SU. In addition, while efficacy, as measured by changes in HbA1c, was similar between treatments, the incidence of hypoglycaemia was lower in patients taking M-Sita.

Two-year vascular hospitalisation rates and associated costs in patients at risk of atherothrombosis in France and Germany: highest burden for peripheral arterial disease.

OBJECTIVES: To obtain Western European perspectives on the economic burden of atherothrombosis in patients with multiple risk factors only (MRF), cerebrovascular disease (CVD), coronary artery disease (CAD), and in the under-evaluated group of patients with peripheral arterial disease (PAD), we examined vascular-related hospitalisation rates and associated costs in France and Germany. DESIGN: The prospective REACH Registry enrolled 4693 patients in France, and 5594 patients in Germany (from December 2003 until June 2004). METHODS: For each country, 2-year rates and costs associated with cardiovascular events and vascular-related hospitalisations were examined for patients with MRF, CVD, CAD, and PAD. RESULTS: Two-year hospitalisation costs were highest for patients with PAD (3182.1€ for France; 2724.4€ for Germany) and lowest for the MRF group (749.1€ for France; 503.3€ for Germany). Peripheral revascularizations and amputations were the greatest contributors to costs for all risk groups. Across all PAD subgroups, peripheral procedures constituted approximately half of the 2-year costs. CONCLUSION: Hospitalisation rates and costs associated with atherothrombotic disease in France and Germany are high, especially so for patients with PAD.

Length and cost of hospital stay of radioiodine ablation in thyroid cancer patients: comparison between preparation with thyroid hormone withdrawal and thyrogen.

PURPOSE: Treatment of thyroid cancer consists of thyroidectomy and radioiodine ablation following thyroid-stimulating hormone (TSH) stimulation. Similar ablation rates were obtained with either thyroid hormone withdrawal (THW) or rhTSH. But with rhTSH, the elimination of radioiodine is more rapid, thus reducing its whole-body retention and potentially resulting in a shorter hospital stay. The aim of this study was to assess the financial impact of a reduced length of hospital stay with the use of rhTSH. METHODS: This was a case-control study of thyroid cancer patients treated postoperatively with 3,700 MBq (100 mCi) radioiodine; 35 patients who received rhTSH were matched with 64 patients submitted to THW according to covariates influencing radioiodine retention. The length of hospitalization (LOH) was estimated for each method according to the threshold of radioiodine retention below which the patient can be discharged from the hospital. The economic analysis was conducted from a hospital perspective. Simulations were performed. RESULTS: For a threshold of 400 MBq, the LOH was 2.4 days and 3.5 days with rhTSH and THW, respectively, and the cost for an ablation stay was, respectively, 2,146 and 1,807 . In the French context, 57% of the acquisition cost of rhTSH was compensated by the reduction of the length of hospitalization. CONCLUSION: By increasing the iodine excretion, rhTSH allows a shorter hospitalization length, which partially compensates its acquisition cost.

Access to care, socioeconomic deprivation and colon cancer survival.

BACKGROUND: The influence of socioeconomic environment on cancer survival has been established in numerous studies in the EU and the US, prognosis being constantly poorer for the most underprivileged patients. AIM: To investigate the influence of distance to care centre and deprivation on colon cancer survival, using a multilevel Cox model and taking into account cancer stage at diagnosis and treatment modalities. METHODS: The study population comprised all cases of colon cancer diagnosed between 1997 and 2000 in two French areas covered by specialized cancer registries (n = 2066). RESULTS: Road distance to the nearest reference care centre was associated with poorer prognosis even after adjustment for stage at diagnosis (P for trend = 0.01). Subgroups analysis showed that this association was maximal for patients with advanced cancer [RR = 1.27 (1.04-1.51); P for trend = 0.015] for whom access to chemotherapy varying according to distance explained the major part of geographic inequalities in survival. CONCLUSIONS: The major effect of distance from reference care centre on survival suggests that current regional health planning does not guarantee equity in cancer management. Improvement in access to adjuvant therapy, especially for patients with advanced cancers, seems crucial for reducing geographic disparities in colon cancer survival.

Sick leave for follow-up control in thyroid cancer patients: comparison between stimulation with Thyrogen and thyroid hormone withdrawal.

INTRODUCTION: The clinical benefits of recombinant human thyroid-stimulating hormone (rhTSH; Thyrogen) are well established as an alternative stimulation procedure to thyroid hormone withdrawal in the diagnostic follow-up of thyroid cancer patients. By avoiding periods of hypothyroidism, patients do not suffer from a decreased quality of life and keep their ability to work. This study compared the frequency, the duration and the cost of sick leave for follow-up control between rhTSH and withdrawal. METHODS: The study population consisted of patients with thyroid carcinoma first treated by thyroidectomy and radioiodine ablation. Patients were recruited at their control visit between October 2004 and May 2006 in three hospitals, both prospectively and retrospectively. Collection data consisted of patient information, job characteristics and duration of sick leave during the month before and the month after control. The valuation of sick leave used the friction cost method. RESULTS: Among the 306 patients included, 292 (95%) completed the entire questionnaire. The mean age was 46.7 years. Among the 194 active patients, patients treated with rhTSH, when compared with patients treated by withdrawal, were less likely to require sick leave (11 vs 33%; P=0.001). The mean duration of sick leave was shorter (3.1 vs 11.2 days; P=0.002) and indirect costs due to absenteeism accounted for 454 Euro +/- 1673 vs 1537 Euro +/- 2899 for withdrawal stimulation. CONCLUSION: For active patients, rhTSH treatment reduced the length and the cost of sick leave by 8.1 days and 1083 Euro per control respectively, when compared with withdrawal treatment.

[Impact of the choice of an antiplatelet therapy for peripheral arterial disease: cost-effectiveness ratio and health economics assessment]. / Impact du choix d'un antiagrégant plaquettaire dans l'artériopathie oblitérante des membres inférieurs sur les pertes de chances et sur les coûts médicaux.

OBJECTIVES: To evaluate in peripheral arterial disease two strategies of antiplatelet therapy (clopidogrel and aspirin) in terms of number of ischemic stroke and hemorrhagic events, to estimate the losses of chances after no-choice of the most favorable strategy and the impact of these losses of chances in terms of days of hospitalizations, to estimate the cost-effectiveness ratio of the most effective and best tolerated strategy. METHOD: The number of patients to be treated to avoid one critical event (ischemic and hemorrhagic events) was calculated from the results of the annual rates established by the CAPRIE trial conducted in a population of French patients with peripheral arterial disease. This number of patients to treat was then extrapolated to the entire French population of peripheral arterial disease patients. The absolute numbers of critical events avoided with clopidogrel in France defined the losses of chances in the case of no-choice of this drug. Estimates in terms of days of hospitalization and cost-effectiveness ratio (in euro per life year gained) were based on data from the French Medical Information System. RESULTS: The number of patients to treat to avoid one ischemic event was 87 and the number of patients to treat to avoid one major hemorrhagic event was 149. In the peripheral arterial disease population, the numbers of ischemic and hemorrhagic events generated by non-treatment with clopidogrel was estimated at 3761 and 2191, respectively i.e. a total of 5952 events per year. These events included: 2025 myocardial infarctions, 1157 ischemic strokes, 579 deaths of vascular origin and 2191 digestive hemorrhages, requiring 60,394 hospitalization days. The cost-effectiveness ratio of clopidogrel was 10,393 euro per life year gained, and was much lower than commonly accepted cost-effective thresholds in Europe, which are around 30,000 euro per life year gained. CONCLUSION: The choice of clopidogrel in patients with peripheral arterial disease improves the prevention of subsequent events (ischemic and hemorrhagic events) with a cost-effectiveness ratio 2 to 3 times lower than the European thresholds accepted by the World Health Organization and avoids 1 day of hospitalization for 5.4 treated patients.

Socioeconomic and geographic determinants of survival of patients with digestive cancer in France.

Using a multilevel Cox model, the association between socioeconomic and geographical aggregate variables and survival was investigated in 81 268 patients with digestive tract cancer diagnosed in the years 1980-1997 and registered in 12 registries in the French Network of Cancer Registries. This association differed according to cancer site: it was clear for colon (relative risk (RR)=1.10 (1.04-1.16), 1.10 (1.04-1.16) and 1.14 (1.05-1.23), respectively, for distances to nearest reference cancer care centre between 10 and 30, 30 and 50 and more than 90 km, in comparison with distance of less than 10 km; P-trend=0.003) and rectal cancer (RR=1.09 (1.03-1.15), RR=1.08 (1.02-1.14) and RR=1.12 (1.05-1.19), respectively, for distances between 10 and 30 km, 30 and 50 km and 50 and 70 km, P-trend=0.024) (n=28 010 and n=18 080, respectively) but was not significant for gall bladder and biliary tract cancer (n=2893) or small intestine cancer (n=1038). Even though the influence of socioeconomic status on prognosis is modest compared to clinical prognostic factors such as histology or stage at diagnosis, socioeconomic deprivation and distance to nearest cancer centre need to be considered as potential survival predictors in digestive tract cancer.

Long-term achievement of the therapeutic objectives of lipid-lowering agents in primary prevention patients and cardiovascular outcomes: an observational study.

AIMS: Lowering elevated cholesterol levels reduces cardiovascular (CV) morbidity and mortality. Nonetheless, most patients treated with lipid-lowering agents (LLA) do not reach recommended therapeutic objectives. In a setting of primary care in France, we investigated the association between LDL-cholesterol goal attainment and the occurrence of CV events in primary prevention patients with multiple CV risk factors (> or = 3). According to national guidelines, the therapeutic objective (TO) for such patients is an LDL-cholesterol value below 130 mg/dL. METHODS: 579 patients treated with LLA and with LDL-cholesterol values documented at least once a year over a period of at least 3 years (2000-2002) were allocated to three groups based on the number of years the TO was attained during the follow-up period: in all 3 years (TO+++: n=145), only part of the time (TO intermediate: n=256), and never (TO---: n=178). CV events (angina pectoris, myocardial infarction, heart failure, stroke, peripheral artery disease) occurring during the last year of observation (2002) were retrospectively collected. The occurrence risk (OR) of CV events was assessed based on TO status, with a logistic regression model to adjust for baseline differences in CV risk factors. RESULTS: Only a quarter of patients attained TO during all 3 study years. CV events during the third year of observation occurred in 5.5%, 10.5% and 12.9% of patients in the TO+++, TO intermediate and TO--- groups, respectively. Compared with TO+++ patients, the risk of CV events increased significantly in TO intermediate (OR=2.34, 95% CI=[1.01-5.39]) and TO--- patients (OR=2.99, 95% CI=[1.26-7.08]). CONCLUSION: In real practice, a prolonged attainment of TO is rarely observed in high CV risk patients treated with LLA as primary prevention. Therapeutic failure is related to an increased incidence of cardiovascular morbidity. Our data strongly support the need to improve adherence to treatment guidelines to achieve effective cardiovascular prevention.

[Cost of an intraperitoneal chemohyperthermia (IPCH) related to cytoreductive surgery]. / Coûts et financement de la chimiohyperthermie intrapéritonéale (CHIP) associée à une chirurgie d'exérèse.

BACKGROUND: A complete cytoreductive surgery followed with an intraperitoneal chemohyperthermia (IPCH) is a new treatment allowing curing some patients with a peritoneal carcinomatosis. The cost of this treatment, evaluated in different countries, is high. In France, we do not have any cost evaluation of this therapy, and this state slows its diffusion in our country. The aim of this study is to evaluate the real cost of maximal cytoreductive surgery with IPCH, and to compare it with the financial support given by the Ministery of Health. MATERIALS AND METHODS: The real cost of this therapy was established on the standard analytic accountancy of our Institute. The analysis of the financial support received was done after the classification of the patients in the current official diagnosis-related groups, and according to the current rates of reimbursing of these acts. RESULTS: Seventy-three patients were treated with IPCH in our Institute during 2002 and 2003. The real mean cost for our hospital was 39,358 euros per patient, with a mean hospital staying of 27.7 days. In counterpart, our hospital received a mean financial support of 20,485 euros, resulting in a deficit of 18,873 euros per patient (and close to 1.4 million of euros for the two years). CONCLUSION: Our current classification of diagnosis-related groups does not allow to describe the real importance of this therapy which combines a maximal cytoreductive surgery with IPCH. In our system of reimbursing, the hospital which offers this type of new therapy to its patients receives only half of the real rate. Two correctives measures are suitable: to describe this combining treatment in the official list of medical acts, and to determine its specific cost for reimbursing.
