Cost effectiveness of using trastuzumab biosimilars compared to trastuzumab original drugs to treat breast cancer in a hospital setting.

INTRODUCTION: Subcutaneous (SC) drug administration, such as the Herceptin® in an oncology day hospital reduces the administration time of trastuzumab. In the context of combination therapy administration, this time-saving may be called into question. The challenge posed by the deployment of much less expensive IV biosimilar forms raises questions about the cost-effectiveness of SC administration. METHODS: Using data from a french Diagnostic Related Groups regarding prescriptions of intravenous Herceptin® (HIV), Herceptin® biosimilar IV (BSIV), and Herceptin® subcutaneous (HSC), we conducted two simulations. This simulation involved replacing all HSC with BSIV in combination therapy administration (Simulation 1) and subsequently substituting IV forms with SC forms only when prescribed as monotherapy (Simulation 2). A cost-benefit analysis was conducted based on these two simulations, from the hospital's perspective, for Normandy's population over a 1-year timeframe. RESULTS: In Simulation 1, there was an average cost-saving of €12 per patient per year, but it resulted in a loss of 10140 min, equivalent to 10 min per patient per year when compared to the current situation. Simulation 2 yielded average cost-savings for the hospital amounting to €51 per patient per year, along with a time-saving of 67 min per patient per year compared to the current situation. CONCLUSIONS: The development of a program aimed at optimizing the prescription of Trastuzumab holds the potential to deliver significant cost-savings to hospitals while enhancing the quality of service provided to the patients. This optimization involves using H SC in monotherapy and BS IV in combination therapy administration.

Therapeutic Treatment Plan Optimization during the COVID-19 Pandemic: A Comprehensive Physicochemical Compatibility Study of Intensive Care Units Selected Drugs.

BACKGROUND: The SARS-CoV-2 pandemic has resulted in a dramatic rise of the demand for medical devices and drugs. In this context, an important shortage of programmable syringe pumps, used to administrate different drugs in intensive care units, was seen. The opportunity of administrating combinations of five intensive care units selected drugs (Sufentanil, Clonidine, Loxapine, Midazolam, and Ketamine) was considered. METHODS: The drug mixtures were studied in a pure form or diluted in NaCl 0.9% or G5%. Twenty-six possible combinations of the five drugs were produced in glass vials or polypropylene syringes and stored at 25 °C for 14 days. The LC method was implemented to study drugs combinations in the presence of the degradation products. The clearness and pH were also monitored. RESULTS: All the 26 possible combinations displayed adequate physicochemical stability at 25 °C: at least 3 days and 7 days, respectively, for the dilution in 0.9% NaCl or glucose 5%, and the pure drug products mixtures. CONCLUSIONS: The study provided sufficient stability results, covering the medication administration period of at least three days. The combination of more than two drugs offers the advantage of minimizing the individual doses and reduces unwanted side-effects. Hence, this study opens up the possibility of combining the five drugs in one single syringe, which is useful especially under the current circumstances associated with an important shortage of programmable syringe pumps and pharmaceuticals.

Introduction of biosimilar pegfilgrastim in France: Economic analysis of switching from originator.

OBJECTIVES: To assess the economic impact of introducing biosimilar pegfilgrastim compared to the current standard granulocyte colony-stimulating factor (G-CSF) practice in France. METHODS: A budget impact model was developed to investigate the impact of introducing pegfilgrastim biosimilar over 5 years. The model analysed drug acquisition costs, ambulatory costs, as well as costs associated with poor outcomes, and compared the current standard practice of long-acting and short-acting G-CSF to a revised practice including pegfilgrastim biosimilar in addition to standard practice treatments. The cost of switching to pegfilgrastim biosimilar, within a pharmacy setting, was analysed within the model using data from a survey of French pharmacists. RESULTS: The budget impact model calculated a cost saving of €51,007,531 over 5 years switching from the current standard practice to pegfilgrastim biosimilar. A sensitivity analysis accounting for variation in pegfilgrastim biosimilar uptake of 1) 15% in year 1 and 1% in years 2-5 and 2) 15% in years 1-5, estimated savings ranging between €29,377,784 and €79,847,194, respectively. A further analysis predicted cost savings of €287,344,835 over 5 years with the extension of pegfilgrastim biosimilar, at an uptake of 15% in year 1 and 7% in years 2-4, to both long-acting and short-acting G-CSF groups compared to unchanged current practice. CONCLUSIONS: The introduction of pegfilgrastim biosimilar will help to reduce cost and alleviate some of the financial pressure on the French healthcare system.

Management of diabetic foot ulcers: a 25% lidocaine topical cream formulation design, physicochemical and microbiological assessments.

Background: Given the importance of surgical debridement in healing of diabetic foot ulcers, effective local anaesthesia is required to manage the related extreme pain. The pharmaceutical proprietary products currently available have low concentrations and do not exceed 5% w/w local anaesthetic. Objective: Formulation design of a lidocaine cream of 25% and assessment of the intrinsic stability. Methods: A cream pharmaceutical form was chosen for its ability to cross the skin barrier and effectively anaesthetise the skin. The choice of cream formula is based on changes in the size of the emulsions and resistance to physical stress. Stability tests were assessed over a 6-month period in terms of physical (evaluation of oil droplets), microbiological (germ count and identification, and preservative antimicrobial efficacy) and chemical parameters (content and pH). Results: Under the study conditions, the drug product displayed good physicochemical and microbiological stability for 6 months at 20°C and 40°C, and no degradation product was detected. Due to the systemic adverse effects of lidocaine, the pH stability guarantee the drug product tolerance along with very weak systemic passage. Conclusions: Given the good physicochemical and microbiological stability of the drug product over 6-month period, it has been made available to the clinical unit. An average of 250 patients per year benefit from the treatment with an excellent efficacy/tolerability ratio.

Unmet needs in clinical nutrition in oncology: a multinational analysis of real-world evidence.

BACKGROUND: Knowledge about cancer-related malnutrition and the use of clinical nutrition (CN) in the real-world setting are lacking. We investigated diagnosis and treatment frequency of malnutrition in a multinational survey to identify unmet needs in cancer patients' care. METHODS: Retrospective analyses were conducted on data from three administrative healthcare datasets from France (n = 570,727), Germany (n = 4642) and Italy (n = 58,468). Data from France described frequency and timing of malnutrition diagnosis in hospitalized gastrointestinal cancer patients. The German data detailed home parenteral nutrition (HPN) use in cancer patients with stage III/IV cancers. The Italian data analysed three cohorts: metastatic with CN, metastatic without CN, and patients without metastatic disease. RESULTS: In France, malnutrition diagnosis at first hospitalization occurred in 10% of patients, 13% were subsequently diagnosed, and 77% had no malnutrition diagnosis. In Germany, 16% of patients received HPN. Patients started HPN around 3 months before death. In Italy, 8.4% of metastatic cancer patients received CN; average time between metastasis diagnosis and first CN prescription was 6.6 months. Average time between first CN prescription and death was 3.5 months. CONCLUSIONS: These data indicate that in the real-world clinical practice, cancer-related malnutrition is under-recognized and undertreated. CN often appears to be prescribed as an end-of-life intervention or is not prescribed at all.Appropriate CN use remains challenging, and current practice may not allow optimal oncologic outcomes for patients at nutritional risk. Improving awareness of malnutrition and generating further evidence on clinical and economic benefits of CN are critical priorities in oncology.

Physical and chemical stability of a generic etoposide formulation as an alternative to etoposide phosphate.

The generic Mylan® etoposide (ETP) has been investigated as an alternative for Etopophos®, in part due to a global shortage of the latter. The generic alternative is different both in its formulation and in its very limited stability (6 h at 25 °C against 4 days for Etopophos®) once reconstituted in ready-to-use chloride or glucose solutions. Its intrinsic stability has been thoroughly studied under various conditions. Two degradation products resulting from hydrolysis were characterized by LC-HR-MSn and supported by density functional theory calculations of the frontier molecular orbitals energies, molecular electrostatic potential mapping, and Mulliken charge analysis. Chemical degradation increases with temperature and can be fitted to a zero order kinetic model with a half-life of 119 days and a kinetic constant of 0.0028 mM day-1. Precipitation was only observed in solutions at 5 °C and -20 °C indicating that at these temperatures the reconstituted solutions are thermodynamically metastable. In conclusion, ETP at concentrations of 0.68 and 1 mM prepared and stored at 25 °C under good manufacturing practices remained unchanged over a period of 21 days irrespective of the nature of the solvents or the type of container.

Antiretroviral drug reduction in highly experienced HIV-infected patients receiving a multidrug regimen: the ECOVIR study.

OBJECTIVES: In a context of life-long therapy, we asked whether it could be possible to reduce the number of antiretroviral drugs without jeopardizing viral suppression. METHODS: ECOVIR was a prospective study aiming to assess whether in patients on combination ART with ≥4 antiretrovirals for ≥24 weeks and virally suppressed for ≥48 weeks, a drug-reduced (DR) regimen could be proposed. The intervention consisted of discontinuing genotypically less susceptible drugs to reach a DR regimen with ≤3 antiretrovirals. The primary endpoint was the proportion of patients maintaining viral suppression at week (W) 24. RESULTS: From 89 eligible individuals for the study, a DR regimen was proposed in 86 (97%) patients, of whom 71 were switched to a DR regimen. Baseline characteristics [median (IQR)] were: age 58 (53-65) years, duration of treatment 24 (21-26) years and viral suppression 8 (6-11) years. The cumulative resistance profile showed full resistance to lamivudine/emtricitabine (91%), abacavir (74%), efavirenz/nevirapine (70%), rilpivirine (56%), darunavir (q24h/q12h) (42%/29%), lopinavir (69%), atazanavir (71%) and raltegravir (24%). The final DR regimen consisted of a two-drug or three-drug regimen in 54 patients (76%) and in 17 patients (24%), respectively. The success rate of a DR regimen at W24 was 93.9% (95% CI 84.4-97.6, Kaplan-Meier estimate). Four patients experienced virological failure (at W4, W8 and W12), all with plasma viral load (pVL) <600 copies/mL and no emergence of resistance mutations. The DR strategy allowed a monthly cost saving of 36%. CONCLUSIONS: In experienced patients with high-level resistance, individualized strategies based on expert advice can offer DR regimen options with fewer drug-drug interactions and a significant economic impact while ensuring virological success.

Infliximab biosimilar for treating neurosarcoidosis: tolerance and efficacy in a retrospective study including switch from the originator and initiation of treatment.

OBJECTIVES: Infliximab is increasingly used to treat neurosarcoidosis. We aimed to determine the efficacy and tolerance of an infliximab biosimilar for treating neurosarcoidosis. METHODS: We conducted a retrospective single-center study to describe the efficacy, safety and immunogenicity of an infliximab biosimilar in neurosarcoidosis patients. We compared the survival time without relapse while receiving the biosimilar or previous originator-infliximab treatment. RESULTS: Twenty patients with histologically documented neurosarcoidosis were treated with an infliximab biosimilar (initiation of treatment in 12 and switch from the originator drug in 8) between February 2016 and August 2018. All patients presenting with neurological involvement of one or more areas, including meningeal (n = 15), cerebral (n = 10), spinal cord (n = 9), and/or cranial nerves (n = 5); epilepsy (n = 3); and/or intracranial hypertension (n = 3) were enrolled. Eighteen patients received glucocorticoids during infliximab treatment, and 16 had methotrexate or azathioprine concomitant treatment. The median duration of follow-up was 25 months (19-28). Six patients relapsed during biosimilar treatment. Relapse rates and time-to-relapse did not differ between the infliximab originator previously received and biosimilar treatment groups (p = 0.40 and 0.51, respectively). Nine patients experienced 11 adverse events with the infliximab biosimilar, including infections (n = 5), urticaria (n = 4), headache (n = 1), and diarrhea (n = 1). All side effects were grade 2 or less using the WHO classification. CONCLUSIONS: In this retrospective study, the infliximab biosimilar was efficacious and safe for treating neurosarcoidosis.

Management and cost analysis of cancer patients treated with G-CSF: a cohort study based on the French national healthcare insurance database.

OBJECTIVES: To describe the management and costs associated with G-CSF therapy in cancer patients in France. METHODS: This study analyzed a representative random population sample from the French national healthcare insurance database, focusing on 1,612 patients with hematological or solid malignancies who were reimbursed in 2013 or 2014 for at least one G-CSF treatment dispensed in a retail pharmacy. Patient characteristics and treatment costs were analyzed according to the type of cancer. Then the costs and characteristics of patients associated with the use of different G-CSF products were analyzed in the sub-set of breast cancer patients. RESULTS: The most frequent malignancies in the database population were breast cancer (23.3%), hematological malignancies (22.2%), and lung cancer (12.4%). The reimbursed G-CSF was pegfilgrastim in 34.1% of cases, lenograstim in 26.7%, and filgrastim in 17.9%. More than one G-CSF product was reimbursed to 21.3% of patients. The total annual reimbursed health expenses per patient, according to the type of G-CSF, were €27,001, €24,511, and €20,802 for patients treated with filgrastim, lenograstim, and pegfilgrastim, respectively. Ambulatory care accounted for, respectively, 35%, 38%, and 41% of those costs. In patients with breast cancer, ambulatory care cost was €7,915 with filgrastim, €7,750 with lenograstim, and €6,989 with pegfilgrastim, and the respective cost of G-CSF was €1,733, €1,559, and €3,668. CONCLUSION: All available G-CSF products have been shown to be effective in cancer patients, and both daily G-CSFs and pegylated G-CSF are recommended in international guidelines. Nevertheless, this analysis of G-CSF reimbursement indicates that the choice of product can markedly affect the total cost of ambulatory care.

Investigating therapeutic usage of combined Ticagrelor and Aspirin through solid-state and analytical studies.

The mainstay treatment for patients with acute coronary syndrome is an oral route dual antiplatelet therapy with a P2Y12-receptor antagonist and Aspirin (ASA). To improve patient adherence to such treatments, combination therapies (polypill) are envisioned. Physicochemical solid-state studies have been carried out to develop a preformulation strategy of ASA with the P2Y12-receptor antagonist Ticagrelor (TIC). The investigations were carried out using differential scanning calorimetry, liquid chromatography-high resolution-multistage mass spectrometry (LC-HR-MSn) and as complementary techniques Fourier transform infrared measurements and thermogravimetric analysis. A simple eutectic transition at 98°C with a mole fraction for the eutectic liquid of 0.457 has been observed and the mixing of ASA and TIC molecules in each other's crystal structures appears to be limited. No cocrystals of TIC and ASA have been found. The appearance of the eutectic liquid was linked with a clear onset of chemical instability of the two pharmaceuticals. The decomposition mechanism in the liquid phase involves prior decomposition of ASA, whose residues react with well-identified TIC interaction sites. Seven interaction products were observed by LC-HR-MSn linked to corresponding degradation products. The most important degradation pathway is N-dealkylation. In conclusion, polypills of ASA and TIC are a viable approach, but the decomposition of ASA should be avoided by eliminating high temperatures and high humidity.

Cost-effectiveness analysis on the use of fidaxomicin and vancomycin to treat Clostridium difficile infection in France.

BACKGROUND: Fidaxomicin is a macrocyclic antibiotic with proven efficacy against Clostridium difficile infection (CDI) in adults. It was licensed in France in 2012, but, due to higher acquisition costs compared with existing treatments, healthcare providers require information on its cost/benefit profile. OBJECTIVE: To compare healthcare costs and health outcomes of fidaxomicin and vancomycin, as reference treatment for CDI. METHODS: A Markov model was used to simulate the treatment pathway, over 1 year, of adult patients with CDI receiving fidaxomicin or vancomycin. Several patient sub-groups (severe CDI; recurrent CDI; concomitant antibiotics; cancer; renal failure; elderly) were evaluated. Cost-effectiveness was analyzed based on cure and recurrence rates derived from published randomized clinical trials comparing fidaxomicin and vancomycin, and costs calculated from the payer perspective using French hospitalization data and drug cost databases. Model outputs included costs in euros (reference year 2014) and health outcomes (recurrence; sustained cure rates). Alternative scenario and sensitivity analyses were performed using data from other clinical trials in CDI, including one conducted in real-life clinical practice in France. RESULTS: Drug acquisition costs were €1,692 higher in fidaxomicin-treated patients, but this was offset by the lower hospitalization costs with fidaxomicin, which were reduced by €1,722. The reduction in the cost of hospitalization was driven by the significantly lower number of recurrences in fidaxomicin-treated patients, offsetting the acquisition cost of fidaxomicin in all sub-groups except recurrent CDI and concomitant antibiotics. CONCLUSION: This study demonstrated that, despite higher acquisition costs, the lower recurrence rate with fidaxomicin resulted in cost savings or low incremental costs compared with vancomycin.

Identification of the major degradation pathways of ticagrelor.

Ticagrelor is a direct-acting and reversible P2Y12-adenosine diphosphate (ADP) receptor blocker used as antiplatelet drug. Forced degradation under various stress conditions was carried out. The degradation products have been detected and identified by high-pressure liquid chromatography multistage mass spectrometry (LC-MS(n)) along with high-resolution mass spectrometry. C18 XTerra MS column combined with a linear gradient mobile phase composed of a mixture of 10 mM acetate ammonium/acetonitrile was shown suitable for drug and impurity determinations and validated as a stability indicating method. Structural elucidation of the degradation products relied on MS(n) studies and accurate mass measurements giving access to elemental compositions. Up to nine degradation products resulting from oxidation/auto-oxidation, S-dealkylation and N-dealkylation have been identified, covering a range of possible degradation pathways for derivatives with such functional groups. Kinetics was also studied in order to assess the molecule's shelf-life and to identify the most important degradation factors.

Cost of managing anemia in end-stage renal disease: the experience of five French dialysis centers.

OBJECTIVE: The aim of this retrospective study was to evaluate the direct cost of anemia treatment in hemodialysis patients and to evidence factors predictive of 1-year cost. METHODS: Retrospective study which included hemodialyzed patients during year 2009 in five centers. Patients were evaluable if they had at least one hemoglobin (Hb) assay per month and were monitored for at least 4 months. Patients were classified in different "annual Hb category" according to their monthly mean Hb [Hb categories: Ideal (10 ≤ Hb ≤ 12 g/dL); High (Hb > 12 g/dL) and Low (Hb < 10 g/dL) if >75% of time in respective category, otherwise classified in the Fluctuating category]. RESULTS: We analyzed 636 patients (male, 59.4%) with a mean age of 67 years who underwent 144 hemodialysis sessions (median number per patient) in 2009. The cost of anemia treatment was largely driven by erythropoiesis-stimulating agents (ESA) (68% of total cost for Low Hb category and approximately 90% for the other Hb categories). Adjusted predictive factors for 1-year direct cost of anemia treatment (p < 0.0001) were dialysis center (2,518-5,617), death (6,091 vs. 4,911), age (4,911 for ≤55 years and 5,378 for 65-75 years), female gender (4,911 vs. 4,398 for male), Low Hb category (13,005 vs. 5,034 for Ideal, 4,911 for Fluctuating and 2,418 for High), serum ferritin level (5,102 for 200-500 µg/mL and 4,646 for ≥500 µg/mL) and duration of dialysis (4,911 if ≤2 years and 2,952 if 4-6 years). LIMITATIONS: Retrospective study, and low number of patients in the Low Hb category. CONCLUSIONS: The main factors that were predictive of 1-year cost of anemia treatment in hemodialysis patients were centers, patients in the Low Hb category, and dialysis duration of less than 2 years.

Real time identification of drug-induced liver injury (DILI) through daily screening of ALT results: a prospective pilot cohort study.

OBJECTIVE: Identification of drug-induced liver disease (DILI) is difficult, even among hospitalized patients. The aim of this pilot study was to assess the impact of a specific strategy for DILI screening. DESIGN: We prospectively compared the number of acute DILI cases identified in one week of a proactive strategy based on centralized elevated ALT values to those identified with a standard of care strategy for 24-week period based on referral cases to the hepatology unit. In the centralized strategy, a designated study biochemist identified patients with ALT greater than 3 times the upper limit of normal values (ULN) and notified the designated hepatologists, who then went to the patients' wards, analyzed the charts, and if necessary, interviewed the identified patients. During these two periods, patients with possible DILI were included after signing an informed consent in an ongoing European diagnostic study (SAFE-T consortium). RESULTS: During the 24-week period of the standard strategy, 12 (0.04%) patients out of a total of 28,145 were identified as having possible DILI, and 11 of these accepted to be included in the protocol. During the one-week proactive period, 7 patients out of a total of 1407 inpatients (0.498%) [odds ratio vs. standard = 12.1 (95% CI, 3.9-32.3); P<0.0001] were identified with possible DILI, and 5 were included in the protocol. CONCLUSION: A simple strategy based on the daily analysis of cases with ALT >3 ULN by designated biochemists and hepatologists identified 12 times more acute cases of drug-induced liver disease than the standard strategy. This pilot cohort is registered on the number AP-HP P110201/1/08-03-2011 and AFSSAPS B110346-70.

A multicenter prospective observational study of the conformity of temozolomide prescriptions in France.

CONTEXT: Temozolomide (TMZ) is approved for the treatment of high-grade gliomas such as glioblastoma (GBM) multiforme and refractory anaplastic astrocytoma, but it is also used in indications not mentioned in the summary of product characteristics (SPC). The main objective of this study was to evaluate the conformity of TMZ prescriptions to the French SPC and prescription guidebook. METHODS: We conducted a prospective observational study of all consecutive patients treated with TMZ in 21 French hospitals between September 2006 and February 2007, accounting for 39% of total TMZ consumption in France. The conformity of TMZ prescriptions was evaluated in terms of the indication, dosage, treatment duration, and combination with other treatments, with respect to the SPC and prescription guidebook. RESULTS: We enrolled 831 patients (median age, 56 years) who received a total of 5982 TMZ treatment cycles. TMZ was mainly prescribed to patients with newly diagnosed GBM (384 patients), GBM in progression/relapse (28 patients), or anaplastic astrocytoma in progression/relapse (19 patients). Prescriptions conformed to the SPC in 51.9% of cases and to the prescription guidebook in 91.5% of cases. Global conformity with the SPC, in terms of the dosage, treatment duration, and combination with other treatments, was 62% for newly diagnosed GBM treated with radiotherapy plus TMZ, 72% for TMZ maintenance monotherapy, and 66% for GBM and anaplastic astrocytoma in progression/relapse. CONCLUSION/DISCUSSION: In France, routine TMZ prescriptions conform to the SPC and practice guidebook. This is one of the largest studies of drug use in neuro-oncology in terms of the number of patients and cycles analyzed.

Perception of alopecia by patients requiring chemotherapy for non-small-cell lung cancer: a willingness to pay study.

OBJECTIVE: Chemotherapy-induced alopecia may have a substantial impact on the quality of life (QOL) of lung cancer patients, but very few data are available. The aim of this study was to assess the perceived impact of alopecia based on a "willingness to pay" (WTP) approach. METHODS: We conducted a prospective multicenter WTP study of patients receiving chemotherapy for non-small-cell lung cancer (NSCLC). The perceived impact of alopecia was assessed with a visual analogue scale (VAS; 0: no impact, 10: major impact), and from the patients' willingness to pay for chemotherapy that had the same efficacy, dosing schedule and tolerability as the standard treatment but that cut the risk of alopecia from 40% to 5%. RESULTS: Among the 135 patients enrolled in this study, the mean score on the VAS for the perceived likely impact of alopecia was 4.4 ± 0.3. The mean WTP for a 3-week chemotherapy cycle reducing the risk of alopecia from 40% to 5% was €83.4 ± 10.2 (€median 37.5), representing 2.1% of total income, while 27% of patients were unwilling to pay anything. There was a significant association between WTP and gender (women, p < 0.01), annual incomes (p < 0.01), but not with marital status, level of education or occupations. CONCLUSION: Alopecia appears to be an important outcome for patients receiving chemotherapy for NSCLC. Women and patients with high annual incomes were more willing to pay.

Estimated annual costs of prophylaxis and treatment of venous thromboembolic events associated with major orthopedic surgery in France.

Venous Thromboembolism (VTE) remains a major complication following orthopedic surgery despite heparin prophylaxis. Clinical consequences associated with this complication are deep vein thrombosis (DVT), pulmonary embolism, and long-term consequences of DVT, especially Postthrombotic syndrome (PTS). The purpose of the present study was to estimate the annual direct costs of VTE following major orthopedic surgery of the lower limb in France. This cost of illness study was performed by using available information from health system databases (1999) and literature and specific surveys (2002). Direct costs were calculated by using estimates of the number of patients with major orthopedic surgery in France during one year. Patients presenting with VTE were identified from the national disease-related group inpatient database. Additional resource consumption was identified by comparison with disease-related groups without the VTE complications. Ambulatory care costs after hospitalization, for recurrences and PTS, were estimated from specific surveys of general practitioners and venous disease specialists. Total annual costs of VTE associated with major orthopedic surgery for the French Sickness Fund were estimated to be approximately 60 million euros over 1 year with 28 million euros for inpatient care and 30 million euros for recurrences and PTS.
