Non-pharmacologic direct cost of a simplified strategy with glecaprevir/pibrentasvir for 8 weeks in naïve non-cirrhotic patients with hepatitis C implemented in clinical practice. The Just SIMPLE Study.

BACKGROUND AND OBJECTIVE: The emergence of highly tolerable, effective, and shorter duration direct-acting antivirals (DAAs) regimens offers the opportunity to simplify hepatitis C virus management but medical costs are unknown. Thus, we aimed to determine the direct medical costs associated with a combo-simplified strategy (one-step diagnosis and low monitoring) to manage HCV infection within an 8-week glecaprevir/pibrentasvir (GLE/PIB) regimen in clinical practice in Spain. PATIENTS AND METHODS: Healthcare resources and clinical data were collected retrospectively from medical charts of 101 eligible patients at 11 hospitals. Participants were adult, treatment naïve subjects with HCV infection without cirrhosis in whom a combo-simplified strategy with GLE/PIB for 8 weeks were programmed between Apr-2018 and Nov-2018. RESULTS: The GLE/PIB effectiveness was 100% (CI95%: 96.2-100%) in the mITT population and 94.1% (CI95%: 87.5-97.8%) in the ITT population. Three subjects discontinued the combo-simplified strategy prematurely, none of them due to safety reasons. Five subjects reported 8 adverse events, all of mild-moderate intensity. Combo-simplified strategy mean direct costs were 754.35±103.60€ compared to 1689.42€ and 2007.89€ of a theoretical 12-week treatment with 4 or 5 monitoring visits, respectively; and 1370.95€ and 1689.42€ of a theoretical 8-week with 3 or 4 monitoring visits, respectively. Only 4.9% of the subjects used unexpected health care resources. CONCLUSIONS: 8-week treatment with GLE/PIB combined with a combo simplified strategy in real-life offers substantial cost savings without affecting the effectiveness and safety compared to traditional approaches.

Roadmap to resuming care for liver diseases after coronavirus disease-2019.

The global pandemic of coronavirus disease-2019 (COVID-19) has led to significant disruptions in healthcare delivery. Patients with chronic liver diseases require a high level of care and are therefore particularly vulnerable to disruptions in medical services during COVID-19. Recent data have also identified chronic liver disease as an independent risk factor for COVID-19 related hospital mortality. In response to the pandemic, national and international societies have recommended interim changes to the management of patients with liver diseases. These modifications included the implementation of telehealth, postponement or cancelation of elective procedures, and other non-urgent patient care-related activities. There is concern that reduced access to diagnosis and treatment can also lead to increased morbidity in patients with liver diseases and we may witness a delayed surge of hospitalizations related to decompensated liver disease after the COVID-19 pandemic has receded. Therefore, it is paramount that liver practices craft a comprehensive plan for safe resumption of clinical operations while minimizing the risk of exposure to patients and health-care professionals. Here, we provide a broad roadmap for how to safely resume care for patients with chronic liver disease according to various phases of the pandemic with particular emphasis on outpatient care, liver transplantation, liver cancer care, and endoscopy.

Overall clinical and economic impact of non-alcoholic fatty liver disease.

OBJECTIVES: to establish the clinical and economic consequences (resource utilization and healthcare costs) of non-alcoholic fatty liver in the setting of the usual clinical practice in Spain. PATIENTS AND METHODS: an observational, retrospective study was performed based on a review of the medical records of adult patients ≥ 18 years of age who sought medical care from 2017 to 2018. Patients were categorized into two groups according to fibrosis stage (estimation method: FIB-4): a) F0-F2; and b) F3-F4 (advanced fibrosis). Follow-up lasted one year. Primary endpoints included comorbidity, concomitant medication, resource utilization and costs. Results were analyzed using a multivariate approach with p < 0.05. RESULTS: a total of 8,151 patients were recruited with a mean age of 61.1 years and 51.5 % were male. By group: a) mild fibrosis n = 7,127, 87.4 %; and b) advanced fibrosis n = 1,024, 12.6 % (6.8 % with liver cirrhosis). The most common comorbidities included 63 % dyslipidemia, 52 % obesity, 52 % hypertension and 35 % diabetes. The average number of drugs used was 2.1 per patient. Patients with advanced fibrosis (F3-F4) had a higher average number of concomitant medications (2.5 vs 2.1; p < 0.001) and a higher AST/ALT ratio (1.1 vs 0.8; p < 0.001). The average cost (patient-year) for subjects with advanced fibrosis, corrected for covariates, was higher (€1,812 vs €1,128, p < 0.001). Age, morbidity, concomitant medication, fibrosis stage and total costs were higher in patients with diabetes. CONCLUSIONS: patients with advanced fibrosis were associated with more comorbidity and concomitant medications, which resulted in higher healthcare costs for the National Health System.

Economic impact of health resource optimisation in the approach to patients with hepatitis C. / Impacto económico de la optimización de los recursos asistenciales en el abordaje del paciente con hepatitis C.

TThe incorporation of direct-acting antiviral agents to the treatment of chronic hepatitis C infection has simplified diagnosis and follow-up, allowing optimisation of health resources (consultations and tests) dedicated to the management of the disease. The aim of this study was to estimate the economic impact of this simplification. Health resource optimisation was estimated through the Delphi method, based on a panel of 36 experts, consisting of Spanish clinicians, and on clinical practice guidelines. The unit costs (€ in 2017) of the health resources included were obtained from Spanish sources. Simplification of the process, as well as liaison between the medical specialist, nurses and the pharmacy service, would generate savings of €591.17 per patient. Likewise, the mean length of consultations would be shorter with regimens of only 1 tablet daily compared with regimens of more than 1 tablet daily.

Value and innovation of direct-acting antivirals: long-term health outcomes of the strategic plan for the management of hepatitis C in Spain.

OBJECTIVE: To assess the long-term healthcare costs and health outcomes in association with the access to new direct-acting antivirals (DAAs), during the first year of the National Strategic Plan for Chronic Hepatitis C (SPCHC) in patients with chronic hepatitis C (CHC) in Spain. METHODS: A decision tree and a lifetime Markov model were developed to simulate the natural history, morbidity, and mortality of a cohort of 51,900 patients with CHC before (pre-DAA strategy) and after (post-DAA strategy) access to DAAs, following SPCHC approval. The percentage of patients treated, transition probabilities, disease management costs, health state utility values, sustained virologic response rates and treatment costs were obtained from the literature and published data from Spain. The results were expressed in terms of costs (€, 2016), quality-adjusted life years (QALYs) and prevention of clinical events, with an annual discount rate of 3%. RESULTS: The post-DAA strategy would prevent 8,667 cases of decompensated cirrhosis, 5,471 cases of hepatocellular carcinoma, 1,137 liver transplants and 9,608 liver-related deaths. The cohort of 51,900 patients would require investments of 1,606 and 1,230 million euros with the post-DAA and pre-DAA strategies, respectively. This would produce 819,674 and 665,703 QALYs. CONCLUSIONS: The use of new DAA-based treatments in CHC patients during the first year after the implementation of the SPCHC significantly reduced long-term morbidity and mortality and increased quality of life; demonstrating that this plan is an efficient use of public health resources.

Cost-effectiveness analysis of two treatment strategies for chronic hepatitis C before and after access to direct-acting antivirals in Spain. / Análisis coste-efectividad de dos estrategias de tratamiento para la hepatitis C crónica: antes y después del acceso a los agentes antivirales de acción directa en España.

OBJECTIVE: To evaluate the cost-effectiveness of a strategy based on direct-acting antivirals (DAAs) following the marketing of simeprevir and sofosbuvir (post-DAA) versus a pre-direct-acting antiviral strategy (pre-DAA) in patients with chronic hepatitis C, from the perspective of the Spanish National Health System. METHODS: A decision tree combined with a Markov model was used to estimate the direct health costs (€, 2016) and health outcomes (quality-adjusted life years, QALYs) throughout the patient's life, with an annual discount rate of 3%. The sustained virological response, percentage of patients treated or not treated in each strategy, clinical characteristics of the patients, annual likelihood of transition, costs of treating and managing the disease, and utilities were obtained from the literature. The cost-effectiveness analysis was expressed as an incremental cost-effectiveness ratio (incremental cost per QALY gained). A deterministic sensitivity analysis and a probabilistic sensitivity analysis were performed. RESULTS: The post-DAA strategy showed higher health costs per patient (€30,944 vs. €23,707) than the pre-DAA strategy. However, it was associated with an increase of QALYs gained (15.79 vs. 12.83), showing an incremental cost-effectiveness ratio of €2,439 per QALY. The deterministic sensitivity analysis and the probabilistic sensitivity analysis showed the robustness of the results, with the post-DAA strategy being cost-effective in 99% of cases compared to the pre-DAA strategy. CONCLUSIONS: Compared to the pre-DAA strategy, the post-DAA strategy is efficient for the treatment of chronic hepatitis C in Spain, resulting in a much lower cost per QALY than the efficiency threshold used in Spain (€30,000 per QALY).

[Cost-utility analysis of triple therapy with telaprevir in treatment-naïve hepatitis C patients]. / Análisis coste-utilidad de la triple terapia con telaprevir en pacientes con hepatitis C no tratados previamente.

INTRODUCTION: The prevalence of Hepatitis C (HCV) in Spain is 2,5%, with a high morbimortality rate. Triple therapy based on telaprevir plus peginterferon/ribavirin ([T/PR]) has demonstrated to be an effective approach in treatment-naïve G1-HCV patients. This analysis evaluated, through a Markov model, the incremental cost-effectiveness ratio of triple therapy compared to peginterferon/ ribavirin ([PR]) alone in naïve patients depending on fibrosis stage, from the Spanish Healthcare Authorities perspective. METHODS: Efficacy results and adverse events incidence were based on the combined results of ADVANCE and OPTIMIZE studies. Adverse events and disease-related costs (€, 2014) were built up from panel expert opinion except from transplant and post-transplant costs, taken from published data. Drug costs were obtained from national databases and adjusted for the mandatory deduction. Outcomes and costs were both discounted at 3%/year. RESULTS: The analysis shows higher costs and improved outcomes associated with [TR/PR] relative to [PR] alone, resulting in an incremental cost-effectiveness ratio (ICER) of €18,288/ QALY for all the cohort, €14,152QALY for moderate fibrosis, €11,364QALY for bridging fibrosis, €15,929/QALY for cirrhosis. Over a lifetime period, the use of [T/PR] could avoid 12 cirrhosis and 4 liver transplants per 1,000 patients compared to [PR] alone. The probabilistic analysis, following 10,000 Montecarlo simulations, demonstrated the probability of an ICER below a €30,000/QALY gained threshold of 69%. At a willingness- to-pay of €30,000/QALY, [T/PR] could be considered as an efficient option compared with [PR] alone for treatment-naïve genotype 1 HCV patients, over a lifetime horizon.

Introduccion: En España, con una prevalencia del 2,5%, la hepatitis C (VHC) se asocia a una elevada morbi-mortalidad. El tratamiento combinado de telaprevir y peginterferon/ribavirina ([T/PR]) es eficaz en pacientes con VHC-G1. El objetivo primario de este estudio fue evaluar la relación coste-utilidad (RCUI) de [T/PR] versus peginterferon alfa 2a/ribavirina ([PR]) en pacientes naïve VHC-G1, según el grado de fibrosis y bajo la perspectiva del sistema sanitario español. Metodología: La eficacia y la incidencia de efectos adversos (EAs) se obtuvieron de los estudios ADVANCE y OPTIMIZE. La estimación de los costes de monitorización, de manejo de EAs y de la enfermedad por estados de salud (€, 2014) fueron proporcionados por el panel de expertos, según bases de costes nacionales, excepto el coste de trasplante y post-trasplante obtenido de publicaciones. Se aplicó la deducción obligatoria a los costes farmacológicos (precio de venta del laboratorio). La tasa de descuento considerada para los costes y beneficios fue 3% anual. Resultados: [T/PR] proporcionó mejores resultados en salud (0,96 Años de Vida Ajustados por Calidad, AVAC) y mayor coste (17.495€) comparado con [PR], resultando una RCUI de [T/PR] versus [PR] de 18.288€/AVAC para toda la cohorte, 14.152€/AVAC para fibrosis moderada, 11.364€/AVAC para fibrosis en puentes y 15.929€/AVAC para cirrosis. Considerando toda la vida del paciente, [T/PR] podría evitar 12 cirrosis y 4 trasplantes cada 1.000 pacientes. Con una RCUI inferior a 30.000€/AVAC en el 69% de las simulaciones del análisis probabilístico [T/PR] sería eficiente versus [PR] en pacientes naïve, independientemente del grado de fibrosis.

Pharmacoeconomic analysis of the treatment of chronic hepatitis C with peginterferon alfa-2a or peginterferon alfa-2b plus ribavirin in Spain.

BACKGROUND: An independent meta-analysis of randomized comparative trials of peginterferons alfa-2a and alfa-2b, both combined with ribavirin, analyzed the probability of achieving a sustained virological response (SVR). OBJECTIVE: To estimate the long-term cost-effectiveness of treatment of patients with chronic hepatitis C with peginterferon alfa-2a (180µg/week) plus ribavirin (800-1200mg/day) vs. alfa-2b (1.5µg/kg/week) plus ribavirin (800-1400mg/day), from the perspective of the Spanish National Health System. METHODS: A Markov model was developed with 7 health states to simulate lifetime disease progression. SVR was calculated from the meta-analysis data. Transition probabilities and health state utilities were obtained from published literature. Direct healthcare costs were obtained from the drug catalog, while costs of disease-related complications were obtained from published studies and healthcare cost database. Costs were expressed in 2010€. The annual discount rate applied was 3.5% for both costs and benefits. RESULTS: SVR rate for treatment with alfa-2a was higher than with alfa-2b; the differences were 6.0%, 7.6% and 8.7% for all genotypes, genotypes 1/4 and genotypes 2/3, respectively. Each patient would gain 0.469, 0.600 and 0.685 life-years and 0.155, 0.198 and 0.227 quality-adjusted life-years with alfa-2a vs. alfa-2b, for the respective genotypes. The cost saving per patient treated with alfa-2a would be €705, €672 and €1900, for all genotypes and for genotypes 1/4 and 2/3, respectively, alfa-2a being dominant. CONCLUSIONS: According to the present model, treatment of patients with chronic hepatitis C with peginterferon alfa-2a is cost-effective compared with peginterferon alfa-2b, both combined with ribavirin.
