ABSTRACT
Objetivo: Avaliar a relação de custo-efetividade e impacto orçamentário (AIO) do tratamento de deficiência de ferro (DF), com ou sem anemia, em pacientes com insuficiência cardíaca (IC) com fração de ejeção reduzida NYHA II e III, com uso de carboximaltose férrica (CMF), comparada ao placebo (não intervenção), sob a perspectiva pagadora da saúde suplementar (SS). Métodos: No modelo econômico, foi utilizada a árvore de decisão, no horizonte temporal de 52 semanas, na perspectiva da SS, sendo mensurados os benefícios clínicos e os custos associados à intervenção. Também foram executadas análises de sensibilidade determinística e probabilística para avaliar possíveis incertezas futuras. A elaboração da AIO foi realizada considerando o horizonte temporal de cinco anos, a população a ser tratada, os diferentes cenários de market share e os custos diretos envolvidos no tratamento atual e no tratamento proposto. Resultados: A razão de custo-efetividade incremental (RCEI) foi de -R$ 20.517,07 para um ano de vida ajustado pela qualidade (QALYs). O impacto da incorporação da CMF na SS gerou uma economia em cinco anos de -R$ 43.945.225. Conclusões: A análise apresentada mostrou que o tratamento com CMF reduziu o custo de hospitalização, o número de consultas ambulatoriais e o custo de outros medicamentos relacionados à IC e proporcionou uma economia anual. Considerando um horizonte de tempo de 52 semanas, a terapia intravenosa com CMF resultou em uma estratégia de redução de custos, quando comparada ao tratamento proposto para a DF em pacientes com IC.
Objective: This study aims to evaluate the cost-effectiveness and budget impact (AIO) of iron carboxymaltose (CMF) for treatment of iron deficiency (ID), with or without anemia, in patients with heart failure (HF) and reduced ejection fraction NYHA II and III compared to placebo (non-intervention), from the perspective of paying supplementary health (SS). Methods: In the economic model, the decision tree was used, with a time horizon of 52 weeks, from the SS perspective, measuring the clinical benefits and costs associated with the intervention. Deterministic and probabilistic sensitivity analyzes were also performed to assess possible future uncertainties. The elaboration of the AIO was carried out considering a time horizon of five years, population to be treated, different market share scenarios and direct costs involved in the current treatment and in the proposed treatment. Results: The incremental cost effectiveness ratio (ICER) was -R$ 20,517.07 for 1 quality-adjusted life year (QALY). The budget impact of incorporation of the CMF in SSprovided savings in five years of -R$ 43,945,225. Conclusions: The presented analysis showed that treatment with CMF reduced the cost of hospitalization, the number of outpatient visits and the cost of other HF-related medications and provided annual savings. Considering a time horizon of 52 weeks, intravenous therapy with CMF resulted in a cost-saving strategy when compared to the proposed treatment for DF in patients with HF.

ABSTRACT Objective: To compare transcatheter aortic valve implantation (TAVI) to conservative treatment in inoperable patients or to valve replacement surgery (SAVR) in patients at high or intermediate surgical risk according to the Society of Thoracic Surgeons (STS), through a systematic review of comprehensive economic evaluations. Evaluate the variability of economic models, parameters, assumptions and their influence on final results. Methods: A literature search was performed in Medline, EMBASE, Cochrane Library, Web of Science, SciELO and International HTA Base and manual search. Complete economic analyzes based on economic models published between 2011 and 2022 in Portuguese, English and Spanish were included. The quality of the studies was evaluated using the QHES (Quality of Health Economic Studies) instrument. Results: Thirty-six studies were included, mostly cost-utility analyses (64%), from Europe (41%), and using efficacy data from the PARTNER studies. The Markov model (61%) was predominant. The cost of the TAVI prosthesis was the most important parameter in the sensitivity analysis in the three groups. The studies achieved a good quality in QHES instrument. Conclusion: TAVI tended to be cost-effective relative to comparators. The models were not homogeneous in parameters, time horizons and discount rate, which may have an impact on the cost-effectiveness of TAVI, making it difficult to compare the results between different countries and perspectives.

OBJECTIVE To evaluate the cost-effectiveness of serplulimab combined with chemotherapy as first-line treatment for advanced esophageal squamous cell carcinoma from the perspective of the Chinese healthcare system. METHODS A partitioned survival model with three health states was constructed for cost-effectiveness analysis. Clinical data were extracted from ASTRUM- 007. Information on parameters such as cost and health utility was derived from related websites and published literature. The quality-adjusted life years （QALYs） was used as the output index to calculate the incremental cost-effectiveness ratio （ICER）， and then compared with three times the per capita gross domestic product （GDP） in China to judge whether it was cost-effective. One- way sensitivity analysis and probabilistic sensitivity analysis were performed to evaluate the robustness of the model； the cost- effectiveness of applying this plan to subgroup patients with programmed cell death-ligand 1 combined positive score （PD-L1 CPS） ≥10 and the scheme in the context of charitable drug donations was explored. RESULTS Among advanced or metastatic oesophageal squamous cell carcinoma patients and patients with PD-L1 CPS ≥10， serplulimab combined with chemotherapy could improve health outcomes with an augmentation of cost， compared with placebo combined with chemotherapy，resulting the ICERs were 599 623.64 yuan/QALY and 629 121.57 yuan/QALY， respectively. Therefore， serplulimab combined with chemotherapy was not cost-effective. Sensitivity analysis of single factor showed that the costs of serplulimab were the crucial factor affecting the ICER； probabilistic sensitivity analysis demonstrated basic analysis results were relatively robust. The results of scenario analysis showed that when all patients met the requirements of the charitable drug donation program， serplulimab combined with chemotherapy was cost-effective； the economic outcome of this scheme was reversed compared with the results of the basic analysis. CONCLUSIONS From Chinese healthcare perspective， first-line treatment with serplulimab in combination with chemotherapy is not a cost-effective option for patients with advanced esophageal squamous cell carcinoma， but it may be an economic option to implement a charitable drug donation program for all patients or if the price of serplulimab is significantly reduced.
ABSTRACT
Abstract A multicenter, randomized controlled clinical trial evaluated the effectiveness of two treatments for deep caries lesions in permanent molars - selective caries removal (SCR) to soft dentin with restoration in a single visit, and stepwise excavation (SW) - regarding pulp vitality for a 5-year follow-up period. The present study aimed to determine the cost-effectiveness of these treatments. Treatments were conducted in two Brazilian cities (Brasília and Porto Alegre). At baseline, 299 permanent molars (233 patients) were treated and 229 teeth (174 patients) were evaluated after 5 years. The discounted cash flow method was adopted. The total cost of each treatment was calculated, and the failure cost (endodontic treatment + restoration) was added to the final cost, according to the 5-year failure rates of each therapy (20% for SCR and 44% for SW). A public health service unit composed of three dentists in 4-hour work shifts was used to calculate the monetary value of the treatments, assuming a total of 528 treatments/month. Considering the 229 teeth evaluated after 5 years (115 SCR and 114 SW), SCR provided savings of 43% (amalgam) and 41% (resin composite) per treatment, compared to SW. The SCR technique provides benefits for public finances (direct economy) and for public health services (increase in the number of treatments performed). Considering that maximizing profit and reducing costs are powerful motivating factors for adopting a certain treatment, this study provides data to better support the decision-making process, regarding the management of deep caries lesions in permanent molars.
ABSTRACT
OBJECTIVE To evaluate the cost-effectiveness of Ferric carboxymaltose injection in the treatment of iron deficiency anemia in adult Chinese patients. METHODS From the perspective of China’s health system， the partitioned survival model was constructed to simulate the treatment process and outcome of patients with iron deficiency anemia using ferric carboxymaltose and iron sucrose based on the ferric carboxymaltose phase Ⅲ clinical trial in China （NCT03591406）. The study period was 1 year. Total costs and quality-adjusted life years （QALYs） were calculated for both treatment regimens， and incremental cost-effectiveness ratios were calculated. Scenario analysis was performed with different assumptions for efficacy parameters between 9th week and the end of 1 year， and from the perspective of China’s health system and the entire society. The sensitivity analysis was also performed. RESULTS In the basic analysis， compared with iron sucrose， incremental effectiveness of ferric carboxymaltose therapy was 0.007 QALYs， with an additional savings of 1 038 yuan per patient. Ferric carboxymaltose therapy was more effective and less costly， presenting an absolute advantage. The results of the scenario analysis and single-factor sensitivity analysis were consistent with the basic analysis. Probability sensitivity analysis showed that when the willingness-to-pay threshold was 1， 2， 3 times gross domestic product per capita in 2022， the probability of ferric carboxymaltose with a cost- effectiveness advantage was 88.2%，94.5% and 97.6%，respectively. CONCLUSIONS For Chinese adults with iron deficiency anemia， ferric carboxymaltose is a cost-effective treatment for iron deficiency anemia， compared with iron sucrose.
ABSTRACT
Objective:To compare the cost-effectiveness of hospitalized Chinese patients undergoing nucleic acid screening strategies for hepatitis B and hepatitis C, immunological screening strategy, and no screening strategy under different willingness to pay (WTP). The results might aid to decision-making for the optimal strategy.Methods:In this study, nucleic acid screening, immunological screening and no screening were used as screening strategies, and China′s GDP in 2021 (80 976 yuan) was used as the threshold of WTP to construct a Markov model. After introducing parameters related to the diagnosis and treatment of hepatitis B and C in inpatients, a cohort population of 100 000 inpatients was simulated by TreeAge Pro 2021 software, the total cost, total health effects, incremental cost-effectiveness ratio and average cost-effectiveness ratio of different screening strategies were calculated, and cost-effectiveness analysis was conducted. Univariate and probabilistic sensitivity analysis were used to assess the impact of parameter uncertainty on the final results.Results:Compared with the non-screening strategy, the incremental total cost of the hepatitis B immunological screening strategy for cohort patients was 11 049 536 yuan, and the incremental cost-effectiveness ratio was 24 762 yuan/quality-adjusted life years (QALY), while the total incremental cost of nucleic acid screening was 19 208 059 yuan, and the incremental cost-effectiveness ratio was 29 873 yuan/QALY; the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 834 yuan/QALY. Compared with the non-screening strategy, the incremental cost-effectiveness ratio of hepatitis C immunological screening strategy was 5 731 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening strategy was 8 722 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 591 yuan/QALY. The results of probabilistic sensitivity analysis showed that when the cost of nucleic acid testing exceeded 214.53 yuan, it was not cost-effective to perform hepatitis B nucleic acid screening under the WTP as 1 fold GDP. When the cost of nucleic acid testing exceeded 132.18 yuan, it was not cost-effective to conduct hepatitis C screening under the WTP as 1 fold GDP.Conclusions:Nucleic acid screening strategy can achieve more cost-effectiveness and is worthy of vigorous promotion. Compared with no screening, both the nucleic acid and immunological screening strategies are cost-effective, and hepatitis nucleic acid screening is the optimal strategy for hospitalized patients.

ABSTRACT
Objective:To analyze the efficacy and cost-effectiveness of probiotics in initial Helicobacter pylori ( H. pylori) eradication therapy. Methods:A total of 267 patients with positive H. pylori infection were randomly assigned to two groups, the control group ( n=133) received a 14-day bismuth agent quadruple therapy and the study group ( n=144) received conventional quadruple therapy plus probiotics from January 2020 to August 2021. Eradication status was assessed 4-12 weeks after treatment. The H.pylori eradication rate, adverse reactions, and cost-effectiveness were compared between the two groups. Results:The H.pylori eradication rate was higher in study group than that in the control group in intention-to-treat (ITT) (80.6%(108/134), 95% CI:73.8%-87.4% vs. 68.4%(91/133), 95% CI:60.4%-76.4%, P=0.022) and per-protocol (83.1%(108/130), 95% CI:76.5%-89.6% vs. 72.2%(91/126), 95% CI:64.3%-80.2%, P=0.037). The incidence of adverse effects in the study group was lower than that in the control group (8.2%(11/134) vs. 18.8%(25/133), χ 2=6.415, P=0.011). Cost-effectiveness analysis showed that compared with the control group, the incremental cost-effectiveness ratio (ICER) of the study group was 1 010.49 yuan. The single factor sensitivity analysis showed that the H.pylori eradication rate of the study group had a greater impact on the results, followed by that of the control group and the cost of bifidobacterium quadruplex viable tablets. The probability sensitivity analysis showed that when the willingness to pay value (WTP) was 2 500 yuan, the probability that the probiotics combined with the bismuth agent quadruple therapy group was more cost-effective than the simple bismuth agent quadruple therapy group was 91.2%. Conclusion:As initial Helicobacter pylori treatment, probiotics combined with the bismuth agent quadruple scheme has a higher eradication rate and a lower incidence of adverse events than the bismuth agent quadruple scheme.
ABSTRACT
OBJECTIVE To conduct the pharmacoeconomic evaluation of empagliflozin in the treatment of heart failure with reduced ejection fraction （HFrEF），and to provide evidence-based reference for rational drug use and medical and healthy decision-making. METHODS A Markov model was used to perform a cost-effectiveness analysis of the regimen of empagliflozin in the treatment of HFrEF ，and to evaluate the cost and effectiveness of standard treatment plan plus empagliflozin （empagliflozin group）vs. standard treatment plan （standard treatment group ）. Clinical parameters were obtained from the EMPEROR-Reduced study；cost and utility data came from the published literatures. The cycle of the model was 1 month and the simulation time was 20 years. Single-factor sensitivity analysis and probability sensitivity analysis were performed to validate the results of cost-effectiveness analysis. RESULTS Compared with the standard treatment group ，each additional quality-adjusted life year in the empagliflozin group cost 37 995.94 yuan more ，which was less than China ’s 1 time GDP per capita in 2020（72 447 yuan）. The results of single factor sensitivity analysis showed that steady-state hospitalization rate of 2 groups was the most important factor affecting the incremental cost-effectiveness ratio . The results of probability sensitivity analysis showed that when the willingness-to-pay threshold （WTP）was 1 time GDP per capita in 2020（72 447 yuan），the probability of empagliflozin group with cost-effectiveness advantage was 58.8％；when the WTP was 3 times GDP per capita in 2020（217 341 yuan），the probability of empagliflozin group with cost-effectiveness advantage was 63.8％. CONCLUSIONS Compared with standard treatment plan alone，standard treatment plan plus empagliflozin is more cost-effective in the treatment of HFrEF. However ，the economic probability is not high.
ABSTRACT
RESUMEN Objetivo. Estimar los beneficios económicos y en salud, por sexo y por quintil de ingreso, del incremento de los precios de los cigarros mediante impuestos en México. Métodos. Con un modelo de costo-efectividad extendido (ECEA, por su sigla en inglés) se estimaron los beneficios distributivos en mujeres y hombres con un escenario de incremento del precio de los cigarros de 44% (de 56,4 pesos mexicanos [MX$] a MX$81,2 por cajetilla), como resultado de triplicar el impuesto específico actual (de MX$0,49/cigarro a MX$1,49/cigarro). El modelo se calibró con fuentes oficiales de información nacional Resultados. Con el incremento del impuesto de un peso por cigarro, cerca de 1,5 millones de fumadores abandonarían el consumo (351 300 mujeres y 1,1 millón de hombres). Así, se evitarían aproximadamente 630 000 muertes prematuras atribuibles al tabaco. La reducción de la carga de enfermedad permitiría ahorros para el sector salud cercanos a MX$42 800 millones y evitaría que más de 250 000 personas (entre ellas, 50 200 mujeres fumadoras) cayeran en situación de pobreza. Además, se recaudarían MX$16 200 millones adicionales por año, de los cuales el quintil más bajo aportaría menos de 3% (1% en el caso de las mujeres de menores ingresos). Conclusiones. La epidemia de tabaquismo tiene patrones claramente diferenciados entre mujeres y hombres y reflejan un componente de género. Si bien los beneficios del impuesto al tabaco en México tendrían magnitudes relativas al estado actual de la epidemia en cada caso, estos podrían contribuir a un objetivo más amplio de justicia social mediante la reducción de las inequidades de género.
ABSTRACT Objective. Estimate economic and health benefits, by sex and income quintile, of tax-based cigarette price increases in Mexico. Methods. An extended cost-effectiveness analysis (ECEA) model was used to estimate distributional benefits for women and men in the scenario of a 44% increase in the price of cigarettes (from 56.4 Mexican pesos [MX$] to MX$81.2 per pack), as a result of tripling the current specific excise tax (from MX$0.49/cigarette to MX$1.49/cigarette). The model was calibrated with official national information sources. Results. With a tax increase of one peso per cigarette, about 1.5 million smokers would quit (351 300 women and 1.1 million men). This would prevent approximately 630 000 smoking-attributable premature deaths. Reducing the burden of disease would save the health sector close to MX$42.8 billion and prevent more than 250 000 people (including 50 200 women smokers) from falling into poverty. It would also result in an additional MX$16.2 billion in revenue per year, of which the lowest income quintile would contribute less than 3% (1% for low-income women). Conclusions. The tobacco epidemic has clearly differentiated patterns between women and men, reflecting a gender component. While the tobacco tax in Mexico would have great benefits with respect to the current state of the epidemic, this could also contribute to the broader goal of social justice by reducing gender inequities.
RESUMO Objetivo. Estimar os benefícios econômicos e de saúde, por sexo e quintil de renda, do aumento dos preços dos cigarros por meio de impostos no México. Métodos. Com um modelo de análise ampliada de custo-efetividade (ECEA, na sigla em inglês), foram estimados os benefícios distributivos em mulheres e homens com um cenário de aumento de 44% no preço dos cigarros (de 56,4 pesos mexicanos [MX$] para MX$ 81,2 por maço), como resultado da triplicação do imposto específico atual (de MX$ 0,49/cigarro para MX$ 1,49/cigarro). O modelo foi calibrado com fontes oficiais de informação nacional. Resultados. Com o aumento do imposto de um MX$ por cigarro, cerca de 1,5 milhão de fumantes abandonariam o consumo (351.300 mulheres e 1,1 milhão de homens). Assim, seriam evitadas aproximadamente 630.000 mortes prematuras atribuíveis ao tabaco. A redução da carga de doenças permitiria uma economia para o setor da saúde de cerca de MX$ 42,8 bilhões e evitaria que mais de 250.000 pessoas (incluindo 50.200 mulheres fumantes) caíssem na pobreza. Além disso, seriam arrecadados MX$ 16,2 bilhões adicionais por ano, dos quais o quintil mais baixo contribuiria com menos de 3% (1% no caso de mulheres de baixa renda). Conclusões. A epidemia de tabagismo tem padrões claramente diferenciados entre mulheres e homens e reflete um componente de gênero. Embora os benefícios do imposto sobre o tabaco no México tenham importância relativa no atual estado da epidemia em cada caso, poderiam contribuir para um objetivo mais amplo de justiça social ao reduzir as desigualdades de gênero.
ABSTRACT
【Objective】 To analyze the cost-effectiveness of ELISA grey area strategy through establishing the health economics model. 【Methods】 The serological grey area strategy evaluation model was composed of screening strategy subdecision tree, pathogen infection subdecision tree and pathogen detection subdecision tree. The key parameters in the model were obtained from literatures and research data. The cost-effectiveness of setting ELISA grey area strategy was compared by software, and multifactor sensitivity analysis was conducted. 【Results】 After setting the ELISA grey area, extra samples(5.86 cases/100 000) with serological false negativity could be detected, including HBV samples at 4.93/100 000, HCV samples at 0.27/100 000, HIV samples at 0/100 000, syphilis samples at 0.66/100 000. To yield an additional seropositive sample out of every 100 000 blood donors, blood center will afford extra 1 million yuan about. 【Conclusion】 Through this study, a cost-effectiveness evaluation model of serological detection strategy was established. Although the ELISA grey area setting can yield a small number of seropositive samples, the cost is much higher than the current affordability.

Objective:To analyze the effectiveness and annual cost-effectiveness of extracorporeal cardiopulmonary resuscitation, ECPR) in adults.Methods:Totally 60 patients received ECPR from April 2015 to March 2020 in Emergency Medicine Department of the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. The patients were grouped by discharge survival/hospital death and shockable/unshockable initial rhythm. Age, gender, initial rhythm, survival rate, ECMO treatment time, time-to-death, length of stay and hospitalization costs were analyzed. All discharged survivors were followed up for 1 year, then cost-effectiveness analysis was performed using total cost of ECPR as the cost and 1-year survival rate as the effect.Results:Fifty-four adult patients with ECPR were enrolled, and 17 (31.5%) patients survived and discharged, of whom 15 (88.2%) patients had good neurological outcomes and survived at 1-year follow-up. The median ECMO time was 5 ( IQR 1-8) d, time-to-death was 4 ( IQR 1-9) d, length of stay was 10 ( IQR 3-18) d, total hospitalization cost was 209 122 ( IQR 121 431-303 822) RMB, and the daily cost was 23 587 ( IQR 13 439-38 217) RMB. The rate of shockable initial rhythm was significantly higher in the discharge survival group than the hospital death group. The survival rate of ECPR patients with shockable initial rhythm was significantly higher than that of patients with unshockable initial rhythm, and there was no difference in cost. Conclusions:ECPR is a resource-intensive treatment with a total cost of about 200 000 RMB. Moreover, the effectiveness and annual cost-effectiveness are superior for patients with shockable initial rhythm.
ABSTRACT
Objective:To compare the cost-effectiveness of parathyroidectomy (PTX) and cinacalcet in treatment of refractory secondary hyperparathyroidism (SHPT) on hemodialysis.Methods:Hemodialysis patients with refractory SHPT treated in China-Japan Friendship Hospital from Jan. 2016 to Jan. 2019 were retrospective studied. 77 patients treated with PTX and 47 patients treated with cinacalcet were included in the study. The two groups were matched according to the baseline variables, and then a cost-effectiveness analysis from the perspective of the whole society was conducted. The effect index was the total effective rate of treatment for each group for 1 year (the treatment was effective if the parathyroid hormone decreases by≥30% after treatment) , and the cost included the direct cost and indirect cost within 1 year of treatment. Then the incremental cost-effectiveness ratio (ICER) of the two treatment options was calculated, and a single-factor sensitivity analysis on the cost was performed.Results:58 cases in PTX group and 30 cases in cinacalcet drug treatment group were finally matched. The average ages were 47.0±10.1 years and 49.7±12.2 years, respectively. There was no statistical difference between baselines ( P>0.05) . The results of probability density regression (Probit regression) showed that the total effective rate of the PTX group was 27.3% higher than that of the cinacalcet drug group at 1 year of treatment ( P<0.01) . The average total cost of 1 year after PTX was 125,700 yuan, the average cost of cinacalcet drug group was 111,000 yuan, and the ICER of PTX relative to cinacalcet was 53,500 yuan. When each cost changes within the set value range, ICER changes from 30,000 yuan to 62,000 yuan. Conclusion:For patients with hemodialysis complicated with refractory SHPT, if the willing payment for each additional effective treatment case is more than 53500 yuan, the PTX treatment scheme is more economical than the drug treatment of cinacalcet, and the research results are stable.
ABSTRACT
OBJECTIVE：To s ystematically review the economics of osimertinib for advanced non-small cell lung cancer （NSCLC），and to provide the reference for clinical application and healthcare decision makers. METHODS ：Retrieved from PubMed，Embase，the Cochrane L ibrary，Health Technology Assessment ，CNKI，Wanfang database ，VIP，CBM，etc.， pharmacoeconomic studies on osimertinib in the treatment of advanced NSCLC were collected from the inception to Apr. 2020. After screening and extracting relevant data ，the quality of the included studies was evaluated by using the Quality of Health Economics Studies （QHES），and the economic research results of the included literatures were systematically evaluated by using descriptive analysis method. RESULTS & CONCLUSIONS ：A total of 10 studies from 7 different countries were included ；QHES scores of the included literatures were 73-93，with an average of 86.8，and the quality of the researches was generally high. All the 10 studies were cost-effectiveness analysis ，including 6 first-line treatment ，4 second-line treatment. Six studies reported the cost discount rate ；only one study used the cost of osimertinib after price reduction for evaluation and analysis. Compared with other epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKI），six studies from different countries showed that osimertinib as the first-line treatment drug had no cost-effectiveness advantage ；cost-effectiveness of second-line treatment of osimertinib was controversial ，compared to chemotherapy. For advanced NSCLC patients ，the second-line treatment of osimertinib after the national centralized negotiation of price reduction has a more cost-effectiveness advantage in China ’s medical service system，while the first-line treatment of osimertinib before price reduction does not have this advantage compared with other EGFR-TKI drugs.
ABSTRACT
Objetivo: Analisar o custo-efetividade da trombólise com alteplase no tratamento de acidente vascular isquêmico (AVCi) agudo em até 4,5 horas após início dos sintomas em comparação com tratamento clínico conservador, sob a perspectiva do Sistema Único de Saúde (SUS) no Brasil. Métodos: Construiu-se um modelo de Markov para simular o tratamento de AVCi agudo e suas consequências em curto e longo prazo. Foram conduzidas análises de custo-efetividade (anos de vida ganhos, AVG) e custo-utilidade (anos de vida ajustados pela qualidade de vida, QALY), considerando um horizonte temporal de tempo de vida. Parâmetros de eficácia e segurança foram obtidos em uma metanálise de dados individuais, considerando tratamento em até 3 horas e 3-4,5 horas. Os custos agudos e crônicos foram obtidos por análise secundária de dados de um hospital público brasileiro e expressos em reais (R$). Foram conduzidas análises de sensibilidade determinística e probabilística. Utilizou-se como limiar de disposição a pagar (LDP) 1 PIB (produto interno bruto) per capita para 2019 no Brasil (R$ 31.833,50). Resultados: O tratamento com alteplase vs. conservador resultou em incremento de 0,22 AVG, 0,32 QALY e R$ 4.320,12 em custo, com razão de custo-efetividade incremental (RCEI) estimada em R$ 19.996,43/AVG e R$ 13.383,64/QALY. Ambas as estimativas foram mais sensíveis a variações na efetividade e nos custos de tratamento agudo com alteplase. Para RCEI/AVG e RCEI/QALY, 70,7% e 93,1% das simulações na análise de sensibilidade probabilística estavam abaixo do LDP, respectivamente. Conclusões: O tratamento com alteplase até 4,5 horas após o início dos sintomas tem elevada probabilidade de ser custo-efetivo na perspectiva do SUS.
Objective: To assess the cost-effectiveness of thrombolysis with alteplase for the treatment of acute ischemic stroke up to 4.5 hours after the onset of symptoms as compared to conservative medical treatment from the perspective of the Brazilian Public Health System. Methods: A Markov model was used to simulate the treatment of acute stroke and the associated short- and long-term consequences. Cost-effectiveness (life-years gained, LYG) and cost-utility (quality-adjusted life years, QALY) analyses were performed considering a lifetime horizon. Efficacy and safety parameters were obtained from a meta-analysis of individual data, considering treatment within 3 hours and 3-4.5 hours after the onset of symptoms. Acute and chronic costs were derived from a secondary analysis of data obtained from a Brazilian public hospital and expressed in Brazilian reais (R$). Probabilistic and deterministic sensitivity analyses were performed. The willingness to pay threshold (WPT) was established as 1 GDP per capita for 2019 in Brazil (R$ 31,833.50). Results: Treatment with alteplase vs. conservative medical treatment was associated with an increase of 0.22 in LYG, 0.32 in QALY, and R$ 4,320.12 in cost. The incremental cost-effectiveness ratio (ICER) was estimated as R$ 19,996.43/LYG and R$ 13,383.64/QALY. Variations in effectiveness and costs of acute alteplase treatment had the greatest impact on sensitivity analyses. Considering ICER/LYG and ICER /QALY, 70.7% and 93.1% of the simulations in probabilistic sensitivity analysis were below the WPT, respectively. Conclusions: Treatment with alteplase up to 4.5 hours after the onset of symptoms has a high probability of being cost-effective from the perspective of the Brazilian Public Health System.

Objective: To assess the utility of number needed to treat (NNT) as a tool for cost effectiveness analysis. Methods: Two monoclonal antibodies (MAbs), used for induction therapy viz basiliximab and daclizumab in renal transplantation, were identified. Pivotal placebo controlled clinical trials, mentioned in the innovator package inserts, were compared and analyzed for acute graft rejection and graft survival at 12 mo. NNT viz-a-vis cost was calculated and compared. Results: Daclizumab was comparable to basiliximab for acute graft rejection (NNT 10 vs. 9) but better for graft survival (20 vs. 25) at 12 mo, when used along with triple drug regimen (cyclosporine, azathioprine and corticosteroid). However, considering the cost of regimen for these drugs, in terms of NNT, basiliximab was more cost effective (INR 12,52,044 vs. 28,70,400 for acute rejection and INR 34,77,900 vs. 57,40,800 for graft survival). On the other hand, when these MAbs were used along with dual drug regimen (cyclosporine and corticosteroid), daclizumab was more cost effective for graft survival at 12 mo. The higher cost of daclizumab regimen (INR 2,87,040 vs. 1,39,116 for basiliximab) was offset by its substantially lower NNT (20 vs. 58-75 for one extra graft survival at 12 mo). Conclusion: This study demonstrates the utility of NNT in ascertaining relative effectiveness of treatment modalities that would help to formulate appropriate healthcare policies.
ABSTRACT
Objetivo: Avaliar a relação de custo-efetividade de mirabegrona como tratamento de primeira escolha de pacientes adultos com síndrome da bexiga hiperativa (SBH) comparada a antimuscarínicos orais comumente prescritos no manejo dessa condição. Métodos: O modelo de Markov foi utilizado, com ciclos mensais e horizonte temporal de um ano, para analisar a relação de custo-efetividade de mirabegrona em comparação a tolterodina, oxibutinina, darifenacina e solifenacina. Os pacientes iniciaram o modelo em tratamento com mirabegrona ou um dos comparadores, sendo distribuídos em cinco níveis de gravidade da doença, de acordo com a frequência miccional e número de episódios de incontinência, e a cada ciclo mensal poderiam melhorar, piorar ou permanecer no mesmo nível de severidade do ciclo anterior. Os resultados foram apresentados por meio de uma razão de custo-efetividade incremental. Resultados: Considerando a perspectiva do sistema de saúde suplementar, o custo total do tratamento com mirabegrona foi de R$ 2.455,26 e os parâmetros de efetividade em 0,491 e 0,498 (melhora na gravidade da incontinência e frequência miccional, respectivamente), sendo mais efetivo que os comparadores. Com relação à perspectiva pública, foi estimado um custo com o tratamento de R$ 1.396,01, com características similares de efetividade. De maneira geral, o tratamento com mirabegrona foi dominante quando comparado à tolterodina e custo-efetivo na comparação com os demais antimuscarínicos, em ambas as perspectivas analisadas. Conclusão: Mirabegrona demonstrou ser a melhor opção para tratamento de primeira escolha da SBH com potencial de redução de custos ao longo do tempo, tanto para o sistema público quanto para o sistema de saúde suplementar brasileiro.
Objective: To assess the cost-effectiveness of mirabegron as first-choice treatment in adult patients with of overactive bladder (OAB) compared to oral antimuscarinics, usually prescribed for this condition. Methods: A Markov model has been adopted, with monthly cycles and a one-year time horizon, to analyze the cost-effectiveness of mirabegron compared to antimuscarinic agents: tolterodine; oxybutynin; darifenacin; and solifenacin. The model started with patients receiving treatment with mirabegron or one of the comparators and then, they were assigned to five disease severity levels according to micturition frequency and number of incontinence episodes, and within each monthly cycle they could improve, worsen or remain at the same symptom severity level. Results were presented using an incremental cost-effectiveness ratio. Results: Considering the Brazilian private perspective, treatment with mirabegron resulted in a total cost of R$ 2,455.26 and effectiveness parameters at 0.491 and 0.498 (improvement in incontinence severity and micturition, respectively), being more effective than the comparators. Regarding the Brazilian public perspective, treatment with mirabegron resulted in a total cost of R$ 1,396.01 with similar effectiveness estimation. In general, a dominance was observed when mirabegron was compared to tolterodine and a cost-effectiveness profile against the other muscarinic antagonists, considering both health perspectives. Conclusion: Mirabegron has proven to be the best option for OAB first-line treatment with potential cost savings over time for both the public and private health care systems in Brazil.

Background: Nigeria ranks third just behind India and China in the global disease burden of pneumococcal disease. The current sustainability approach for an affordable pneumococcal conjugate vaccine (PCV) for the national immunization program from 2014 till 2025 involves a cost sharing plan funded with a 75% financial support from GAVI and a subsidy from Pfizer pharmaceuticals. There is a strong need to generate evidence on the cost-effectiveness of the national PCV program in Nigeria from 2014-2025 and beyond 2025.Methods: The following parameters (demography, disease burden, health services utilization and costs, vaccination coverage, vaccine efficacy, and vaccination costs) were used in a static cohort model to estimate the total cost, health and economic benefit, and cost-effectiveness of the implementation of PCV vaccination program, compared with no PCV vaccination among under-five children in Nigeria from 2014-2025 and from 2026-2033. A sensitivity analysis was conducted to evaluate the robustness of the data used.Results: The national PCV vaccination program would have an approximated 31.4% and 30% reduction of the total burden of pneumococcal diseases over the period of 2014-2025 and 2026-2033 respectively. One-way sensitivity analysis reveals vaccine efficacy as most sensitive parameter followed by disease incidence rate and treatment cost. Removal and addition of DTP3 and 3+1 (measles vaccine) dose respectively resulted to a similar ICER from both.Conclusions: The estimated ICER suggests that the national PCV program in Nigeria will be cost-effective post 2025 era. In addition, it is recommended for policy-makers adoption considering the budget and equity impact of the intervention in Nigeria.
