ABSTRACT
Abstract: Brazil has the second largest number of leprosy cases (a disease with a significant burden) in the world. Despite global and local efforts to eliminate this public health problem, inadequate or late diagnosis contribute to perpetuate its transmission, especially among household contacts. Tests such as the rapid IgM antibody detection (RT) and real-time polymerase chain reaction (RT-PCR) were developed to overcome the challenges of early diagnosis of leprosy. This study aimed to analyze the cost-effectiveness of a new diagnostic algorithm recommended by the Brazilian government to diagnose leprosy in household contacts of confirmed leprosy cases, which includes the RT and RT-PCR tests. A decision tree model was constructed and the perspective of the Brazilian Unified National Health System (SUS) and a 1-year time horizon were adopted. Only direct medical costs related to diagnostic tests were included. Effectiveness was measured as the number of avoided undiagnosed leprosy cases. Different scenarios were analyzed. The sequential use of RT, slit-skin smear (SSS) microscopy, and RT-PCR as recommended by the Brazilian Ministry of Health was compared to a base case (isolated SSS microscopy), yielding an incremental cost-effectiveness ratio of USD 616.46 per avoided undiagnosed leprosy case. Univariate sensitivity analysis showed that the prevalence of leprosy among household contacts was the variable that influenced the model the most. This is the first economic model to analyze a diagnostic algorithm of leprosy. Results may aid managers to define policies and strategies to eradicate leprosy in Brazil.
Resumo: O Brasil tem o segundo maior número de casos de hanseníase (doença com carga significativa) do mundo. Apesar dos esforços globais e locais para eliminar esse problema de saúde pública, o diagnóstico inadequado ou tardio contribui para perpetuar sua transmissão, especialmente entre contatos intradomiciliares. Exames como o teste rápido de anticorpos IgM (RT) e a reação em cadeia da polimerase em tempo real (RT-PCR) foram desenvolvidos para superar as barreiras do diagnóstico precoce da hanseníase. Este estudo teve como objetivo analisar a relação custo-efetividade de um novo algoritmo de diagnóstico recomendado pelo governo brasileiro para diagnosticar a hanseníase em contatos domiciliares de casos confirmados de hanseníase, que inclui os testes RT e RT-PCR. Foi construído um modelo de árvore de decisão e adotada a perspectiva do Sistema Único de Saúde (SUS) considerando o período de um ano. Foram incluídos apenas os custos médicos diretos relacionados aos exames diagnósticos. A efetividade foi medida considerando o número de casos evitados de hanseníase. Diferentes cenários foram analisados. O uso sequencial de RT, baciloscopia e RT-PCR, conforme recomendado pelo Ministério da Saúde, foi comparado a um caso base (baciloscopia isolada), obtendo-se uma razão de custo-efetividade incremental de USD 616,46 por caso evitado de hanseníase. A análise de sensibilidade univariada mostrou que a prevalência de hanseníase entre contatos intradomiciliares foi a variável que mais influenciou o modelo. Este é o primeiro modelo econômico a analisar um algoritmo diagnóstico da hanseníase. Os resultados poderão auxiliar os gestores na definição de políticas e estratégias para a erradicação da hanseníase no Brasil.
Resumen: Brasil tiene el segundo mayor número de casos de lepra (enfermedad con carga significativa) del mundo. A pesar de los esfuerzos globales y locales para eliminar ese problema de salud pública, el diagnóstico inadecuado o tardío contribuye a perpetuar su transmisión, sobre todo entre contactos intradomiciliarios. Los exámenes como la prueba rápida de anticuerpos IgM (RT) y la reacción en cadena de la polimerasa en tiempo real (RT-PCR) se desarrollaron para superar las barreras del diagnóstico precoz de la lepra. El objetivo de este estudio fue analizar la relación de costo-efectividad de un nuevo algoritmo de diagnóstico recomendado por el gobierno brasileño para diagnosticar la lepra en contactos domiciliarios de casos confirmados de lepra, que incluye las pruebas RT y RT-PCR. Se construyó un modelo de árbol de decisión y se adoptó la perspectiva del Sistema Único de Salud (SUS) teniendo en cuenta el periodo de un año. Solo se incluyeron los costos médicos directos relacionados con los exámenes diagnósticos. Se midió la efectividad teniendo en cuenta el número de casos de lepra evitados. Se analizaron distintos escenarios. Se comparó el uso secuencial de RT, baciloscopia y RT-PCR, conforme el Ministerio de Salud recomienda, con un caso base (baciloscopia aislada), y se obtuvo un cociente de costo-efectividad incremental de USD 616,46 por cada caso de lepra evitado. El análisis de sensibilidad univariante mostró que la prevalencia de lepra entre contactos intradomiciliarios fue la variable que más influyó el modelo. Este es el primer modelo económico que analiza un algoritmo diagnóstico de lepra. Los resultados podrán ayudar los gestores a definir políticas y estrategias para erradicar la lepra en Brasil.
ABSTRACT
Antecedentes: El departamento del Cauca en Colombia es multiétnico, multicultural y biodiverso, también con grandes diferencias en bajo peso al nacer (BPN), mortalidad perinatal y mortalidad neonatal tardía entre municipios. Objetivo: Determinar la relación de costo-efectividad del control prenatal (CPN) cuando ha tenido buena calidad frente al que ha tenido calidad deficiente con respecto al BPN en el departamento del Cauca entre 2018 y 2020. Método: Evaluación económica con diseño epidemiológico de una cohorte histórica desde la perspectiva de la institución pagadora. Se calculó la razón incremental de costo-efectividad (RICE), análisis de sensibilidad e impacto presupuestal. Resultados: La incidencia de BPN fue del 8,3% (348/4182). La calidad deficiente en el CPN incrementó el riesgo de BPN (OR: 3,38; IC95%: 1,05-8,2) y la buena calidad tuvo una mejor relación de costo-efectividad (RICE: USD 2727,75), con posición dominante frente a la calidad deficiente (6,14 veces el PIB per cápita de ahorro) y con un impacto presupuestal de USD 2.904.392. Conclusiones: La buena calidad del CPN en el departamento del Cauca durante 2018-2020 fue costo-efectiva y dominante por ser de menor costo y mayor efectividad.
Background: The department of Cauca in Colombia is multiethnic, multicultural, and biodiverse, also with large differences in low birth weight (LBW), perinatal mortality, and late neonatal mortality among municipalities. Objective: To determine the cost-effectiveness relationship of antenatal care (ANC) when it has had good quality compared to that which has had poor quality with respect to low birth weight in the department of Cauca between 2018 and 2019. Method: Economic evaluation with epidemiological cohort design historical from the perspective of the payer institution. Incremental cost-effectiveness ratio (RICE), sensitivity analysis, and budgetary impact were calculated. Results: The incidence of LBW was 8.3% (348/4182). Poor quality in ANC increased the risk of LBW (OR: 3.38; CI95%: 1.05-8.2), good quality had a better cost-effectiveness ratio (RICE: USD 2727.75), with dominant position against poor quality (6.14 times the GDP/capita savings) with a budgetary impact of USD 2,904,392. Conclusions: The good quality of the ANC in the department of Cauca during 2018-2020 was cost-effective and dominant because it is lower cost and more effective.

ABSTRACT Introduction For the reduction of PTH levels, two classes of drugs are available in the Brazilian market: non-selective and selective vitamin D receptor activators and calcimimetics. Among the mentioned drugs, the SUS provides oral calcitriol, paricalcitol and cinacalcet. Objectives: Develop cost-effectiveness (CE) and budgetary impact (BI) analysis of cinacalcet versus paricalcitol for patients on dialysis with SHPT, from the perspective of SUS. Methodology: A decision tree model was constructed for CE analysis, which considered the outcome of avoided parathyroidectomy and a time horizon of 1 year. As for the BI analysis, two scenarios were considered, one of which was measured demand and other epidemiological, based on data from the Brazilian Society of Nephrology (BSN). Results: The CE analysis showed that the use of cinacalcet results in one-off savings of R$1,394.64 per year and an incremental effectiveness of 0.08, in relation to avoided parathyroidectomy. The incremental CE ratio (ICER) was - R$ 17,653.67 per avoided parathyroidectomy for cinacalcet, as it was more effective and cheaper compared to paricalcitol. As for the BI analysis, it was estimated that the incremental BI with the expansion of the use of cinacalcet in the SUS will be between - R$ 1,640,864.62 and R$ 166,368.50 in the first year, considering the main and the epidemiological scenarios. At the end of 5 years after the expansion of use, an BI was estimated between - R$ 10,740,743.86 and - R$ 1,191,339.37; considering the same scenarios. Conclusion: Cinacalcet was dominant to avoid parathyroidectomies, being cost-effective.
RESUMO Introdução: Para a redução dos níveis do paratormônio (PTH) estão disponíveis no mercado brasileiro duas classes de medicamentos: ativadores do receptor da vitamina D (não seletivos e seletivos) e calcimiméticos. Dentre os medicamentos supracitados, o SUS disponibiliza calcitriol oral, paricalcitol e cinacalcete. Objetivos: Desenvolver análise de custo-efetividade (CE) e de impacto orçamentário (IO) do cinacalcete versus paricalcitol para pacientes em diálise com HPTS, na perspectiva do SUS. Metodologia: Foi construído um modelo de árvore de decisão para a análise de CE, que considerou o desfecho paratireoidectomia evitada e um horizonte temporal de 1 ano. Quanto à análise de IO, foram considerados dois cenários, um de demanda aferida e outro de abordagem epidemiológica, baseado nos dados da Sociedade Brasileira de Nefrologia (SBN). Resultados: A análise de CE mostrou que o uso de cinacalcete resulta em economia de R$ 1.394,64 ao ano e efetividade incremental de 0,08, em relação a paratireoidectomia evitada. A razão de CE incremental (RCEI) foi de - R$ 17.653,67 por paratireoidectomia evitada para o cinacalcete, já que se mostrou mais efetivo e mais barato comparado ao paricalcitol. Estimou-se que o IO incremental com a ampliação do uso do cinacalcete no SUS estará entre - R$ 1.640.864,62 e R$ 166.368,50 no primeiro ano, considerando os cenários principal e epidemiológico baseado nos dados da SBN. Já ao final de 5 anos após a ampliação do uso, estimou-se um impacto incremental entre - R$ 10.740.743,86 e - R$ 1.191.339,37; considerando os mesmos cenários. Conclusão: Cinacalcete foi dominante para evitar paratireoidectomias, sendo custo-efetivo.
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.

Objetivo: Analisar o impacto orçamentário da adoção de dispositivos contraceptivos reversíveis de longa duração em uma operadora de plano de saúde localizada no Sul do Brasil. Especificamente, analisamos a incorporação do implante subdérmico de etonogestrel (Implanon®) como alternativa ao sistema intrauterino de levonorgestrel (DIU Mirena® ou DIU Kyleena®), ao longo de um período de 15 anos. Métodos: Realizamos uma análise do impacto orçamentário incremental, considerando a inclusão gradual do implante subdérmico de etonogestrel. Foram considerados dados de uma operadora de planos de saúde com mais de 600.000 beneficiários. O horizonte temporal de 15 anos permitiu uma avaliação abrangente dos efeitos financeiros. Resultados: Identificamos 5.345 pacientes elegíveis para a utilização de contraceptivos reversíveis de longa duração. No cenário em que somente o sistema intrauterino de levonorgestrel era adotado, projetou-se um impacto orçamentário total de R$ 746.379.857,80 ao longo de 15 anos. No cenário alternativo, com a incorporação gradual do implante subdérmico, o impacto orçamentário total foi calculado em R$ 689.800.196,83. Isso resultou em um impacto orçamentário incremental negativo de -R$ 56.579.660,97 ao longo do período. Conclusão: A análise de impacto orçamentário realizada indica um potencial benefício financeiro ao adotar o implante subdérmico de etonogestrel como alternativa ao sistema intrauterino de levonorgestrel para contracepção. Esse achado sugere possíveis reduções de custos na área de saúde suplementar no Brasil, reforçando a importância de avaliar opções economicamente viáveis.
Objective: To analyze the budgetary impact of the adoption of long-acting reversible contraceptive devices in a health plan operator located in southern Brazil. Specifically, we analyzed the incorporation of the etonogestrel subdermal implant (Implanon®) as an alternative to the levonorgestrel intrauterine system (Mirena® IUD or Kyleena® IUD), over a period of 15 years. Methods: We performed an analysis of the incremental budgetary impact, considering the gradual inclusion of the etonogestrel subdermal implant. Data from a health plan operator with more than 600,000 beneficiaries were considered. The 15-year time horizon allowed for a comprehensive assessment of the financial effects. Results: We identified 5,345 patients eligible for the use of long-acting reversible contraceptives. In the scenario where only the levonorgestrel intrauterine system was adopted, a total budget impact of BRL 746,379,857.80 was projected over 15 years. In the alternative scenario, with the gradual incorporation of the subdermal implant, the total budgetary impact was calculated at BRL 689,800,196.83. This resulted in a negative incremental budgetary impact of -R$56,579,660.97 over the period. Conclusion: The budget impact analysis carried out indicates a potential financial benefit in adopting the etonogestrel subdermal implant as an alternative to the levonorgestrel intrauterine system for contraception. This finding suggests possible cost reductions in the supplementary healthcare area in Brazil, reinforcing the importance of evaluating economically viable options.

Objetivo: Comparar o implante transcateter de valva aórtica (TAVI) ao tratamento conservador em pacientes inoperáveis ou à cirurgia de troca valvar (SAVR) em pacientes com risco cirúrgico alto ou intermediário conforme a Society of Thoracic Surgeons (STS), por meio de uma revisão sistemática de avaliações econômicas completas. Avaliar a variabilidade de modelos econômicos, parâmetros, pressupostos e sua influência nos resultados finais. Métodos: Foi realizada uma busca da literatura nas bases Medline, EMBASE, Cochrane Library, Web of Science, SciELO e International HTA Base e busca manual. Foram incluídas análises econômicas completas baseadas em modelos econômicos publicadas entre 2011 e 2022, em português, inglês e espanhol. A qualidade dos estudos foi avaliada usando o instrumento QHES (Quality of Health Economic Studies). Resultados: Foram incluídos 36 estudos, majoritariamente análises de custo-utilidade (64%), da Europa (41%), utilizando dados de eficácia dos estudos PARTNER. O modelo de Markov (61%) foi predominante. O custo da prótese do TAVI foi um parâmetro de impacto na análise de sensibilidade nos três grupos. Os estudos alcançaram uma boa qualidade no instrumento QHES. Conclusão: O TAVI tendeu a ser custo-efetivo em relação aos comparadores. Os modelos não foram homogêneos nos parâmetros, horizontes temporais e taxa de desconto, podendo impactar a custo-efetividade do TAVI e dificultar a comparação dos resultados entre diferentes países e perspectivas.
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.

ABSTRACT Purpose: To present the results of a retrospective study regarding the clinical and economic impact of intracameral cefuroxime administration to prevent endophthalmitis during cataract surgery in a referral hospital. Methods: This study included 16,902 eyes from patients who had undergone cataract surgery between 2013 and 2017. From May 2014 onwards, all patients received routine intracameral injections of 1 mg cefuroxime (10 mg/1 mL) after phacoemulsification. The prophylactic efficacy was evaluated using the relative risk ratio, whereas the economic impact was evaluated using number needed to treat to avoid endophthalmitis. Results: Before introducing cefuroxime, 3,407 cataract surgeries were performed using the phacoemulsification technique, and 7 post-operatory cases of endophthalmitis occurred (0.2% incidence). After introducing the cefuroxime protocol, 13,495 surgeries were performed, and 4 endophthalmitis cases were registered (0.03% incidence). Cefuroxime was identified as a protective factor against the development of endophthalmitis [risk ratio = 14%, p=0.002, 95% confidence interval (CI) 95%, 4%-49%], with an economic impact of number needed to treat = 568. The potential savings with cefuroxime was approximately US $2,334.36 for every 568 patients treated. Conclusion: The incidence of endophthalmitis decreased by 86% (risk ratio = 14%, p=0.002, 95% CI, 4%-49%) after introducing intracameral cefuroxime prophylaxis at the study hospital. The results presented herein provide strong evidence for the use of cefuroxime in endophthalmitis prophylaxis after phacoemulsification surgeries, outperforming the alternative by providing both economic and clinical benefits.
RESUMO Objetivo: Apresentar os resultados de um estudo retrospectivo sobre o impacto clínico e econômico da administração de cefuroxima intracameral para prevenir endoftalmite nas cirurgias de catarata em um hospital de referência. Métodos: Este estudo incluiu 16.902 olhos de pacientes submetidos à cirurgia de catarata entre 2013 e 2017. A partir de maio de 2014, todos os pacientes receberam rotineiramente uma injeção intracameral de 1mg de cefuroxima (10mg/1mL) ao final da cirurgia de facoemulsificação. A eficácia da profilaxia foi avaliada usando o risco relativo e o impacto econômico foi avaliado com o número necessário para tratar para se evitar um caso de endoftalmite. Resultados: Antes da introdução do protocolo da cefuroxima, foram realizadas 3.407 cirurgias de catarata por facoemulsificação e ocorreram 7 casos de endoftalmite pós-operatória (incidência de 0,2%). Após a introdução do protocolo da cefuroxima, foram realizadas 13.495 cirurgias e registrados 4 casos de endoftalmite (incidência de 0,03%). A cefuroxima foi um fator de proteção no desenvolvimento de endoftalmite (risco relativo = 14%, p=0,002, Intervalo de Confiança de 95% [IC 95%], 4% - 49%) e o impacto econômico do número necessário para tratar = 568. A economia potencial com a cefuroxima foi de aproximadamente US$ 2.334,36 para cada 568 pacientes tratados. Conclusão: A incidência de endoftalmite diminuiu 86% (risco relativo = 14%, p=0,002, IC 95% 4% - 49%) desde a introdução da profilaxia com cefuroxima intracameral no hospital do estudo. Os resultados apresentados mostram forte evidência para o uso da cefuroxima na profilaxia da endoftalmite após cirurgias de facoemulsificação, por proporcionar economia de custos e benefício clínico.
ABSTRACT
Introduction: India has a huge disease burden of thalassemia major with an estimated 40 million carriers and over a million thalassemia major patients. Very few patients are optimally treated, and the standard of care “hematopoietic stem cell transplant” (HSCT) is out of reach for most patients and their families. The cost of HSCT is significant, and a substantial proportion of it goes to human leukocyte antigen (HLA) testing of family members (HLA screening) in hope of getting a matched related donor (MRD) for HSCT. The aim of this study was to establish that a new proposed testing algorithm of HLA typing would be more cost-effective as compared to the conventional HLA screening within MRD families for possible HSCT. Material and Methods: Buccal swab samples of 177 thalassemia patients and their prospective family donors (232) were collected. Using a new HLA testing algorithm, samples were tested for HLA typing in a sequential manner (first HLA-B, then HLA-A, and finally HLA-DR) using the sequence-specific oligonucleotide probe method on the Luminex platform. Results: The new sequential HLA-A, HLA-B, and HLA-DRB1 testing algorithm showed a 49.1% reduction in cost compared to the conventional HLA testing algorithm. Furthermore, 40 patients (22.59%) were found to have HLA-MRD within the family among other samples that were tested. Conclusion: The new HLA testing algorithm proposed in the present study for identifying MRD for HSCT resulted in a substantial reduction in the cost of HSCT workup.
ABSTRACT
Background: Venous thromboembolism (VTE) is one of the most well-known and feared sequelae of orthopaedic surgery. VTE is relatively common after arthroplasty, prophylaxis has been prescribed. The frequency of postoperative thromboembolic events increased in the absence of primary prevention. Following operations, immobilisation of a lower limb that restricts calf muscle contraction has been shown to be a key risk factor for VTE. VTE is the most frequent source of readmission in orthopaedic patients who have undergone major procedures. It should be emphasized that the best mechanical method for preventing VTE is early walking. Medication for VTE prophylaxis is prescribed more often than mechanical prophylaxis. After major orthopaedic surgery, anticoagulant treatment is essential for reducing morbidity and death. Following hospital discharge, prophylactic drug therapy aims to reduce the morbidity and mortality episodes associated with DVT and PE occurrences. Aspirin use for prevention of VTE following THA and TKA has gained popularity, especially among orthopaedic surgeons due to a minimal risk of postoperative haemorrhage, it also reduces the incidence of recurrent DVTs. Conclusion: Due to its low cost and easy administration without the requirement for regular blood testing, aspirin thromboprophylaxis following knee surgery appears promising. Aspirin saved more QALYs and was cost-effective. Aspirin was demonstrated to have a higher VTE prophylaxis profile than other medications with a time-related association to early mobilisation, healthier patients and medication compliance.
ABSTRACT
Abstract Introduction: Hyperparathyroidism (SHPT) secondary to chronic kidney disease (CKD) is characterized by high levels of parathyroid hormone (PTH), hyperplasia of the parathyroid glands and cardiovascular disease. Selective and non-selective and selective vitamin D-receptor activators, calcimimetics, are available in the Brazilian market to reduce PTH levels. Objectives: To develop a cost-effectiveness (C/E) and budgetary impact (BI) analysis of intravenous paricalcitol vs. oral calcitriol for patients on dialysis with SHPT, from the perspective of the Brazilian Public Health Care System (SUS). Methodology: We built a decision-tree model to analyze C/E, which considered the outcome of avoided death and a time horizon of 1 year. As for the BI analysis, two scenarios were considered, one of demand and one of epidemiological approach, based on data from the Brazilian Society of Nephrology. Results: The analysis showed that the C/E ratio was R$ 1,213.68 per year, and an incremental effectiveness of 0.032, referring to avoided death. The incremental C/E ratio was R$37,927.50 per death averted by paricalcitol. It was estimated that the incremental BI with the expansion of paricalcitol use will be between R$1,600,202.28 and R$4,128,565.65 in the first year, considering the main and epidemiological scenarios. At the end of 5 years after the expansion of its use, an incremental BI was estimated between R$ 48,596,855.50 and R$ 62,90,555.73. Conclusion: Intravenous paricalcitol has superior efficacy and similar safety to oral calcitriol, reducing the overall mortality of dialysis patients, although it implies a higher cost.
Resumo Introdução: O hiperparatireoidismo secundário (HPTS) à doença crônica renal (DRC) é caracterizado por elevados níveis de paratormônio (PTH), hiperplasia das glândulas paratireoides e doença cardiovascular. Para a redução dos níveis do PTH, estão disponíveis no mercado brasileiro os ativadores não seletivos e seletivos do receptor da vitamina D e os calcimiméticos. Objetivos: Desenvolver análise de custo-efetividade (C/E) e de impacto orçamentário (IO) do paricalcitol intravenoso vs. calcitriol oral para pacientes em diálise com HPTS, na perspectiva do Sistema Único de Saúde. Metodologia: Foi construído um modelo de árvore de decisão para a análise de C/E, que considerou o desfecho morte evitada e um horizonte temporal de 1 ano. Quanto à análise de IO, foram considerados dois cenários, sendo um de demanda aferida e um de abordagem epidemiológica, baseado nos dados da Sociedade Brasileira de Nefrologia. Resultados: A análise mostrou que a relação de C/E foi de R$ 1.213,68 ao ano, e uma efetividade incremental de 0,032, referente à morte evitada. A razão de C/E incremental foi de R$ 37.927,50 por morte evitada para o paricalcitol. Estimou-se que o IO incremental com a ampliação do uso do paricalcitol estará entre R$ 1.600.202,28 e R$ 4.128.565,65 no primeiro ano, considerando os cenários principal e o epidemiológico. Já no fim de 5 anos após a ampliação do uso, estimou-se IO incremental entre R$ 48.596.855,50 e R$ 62.90.555,73. Conclusão: O paricalcitol intravenoso tem eficácia superior e segurança semelhante ao comparador calcitriol oral, diminuindo a mortalidade geral dos pacientes em diálise, embora implique maior custo.
ABSTRACT
OBJECTIVE@#This study aims to estimate the cost-effectiveness of the combined chemotherapy regimen containing Bedaquiline (BR) and the conventional treatment regimen (CR, not containing Bedaquiline) for the treatment of adults with multidrug-resistant tuberculosis (MDR-TB) in China.@*METHODS@#A combination of a decision tree and a Markov model was developed to estimate the cost and effects of MDR patients in BR and CR within ten years. The model parameter data were synthesized from the literature, the national TB surveillance information system, and consultation with experts. The incremental cost-effectiveness ratio (ICER) of BR vs. CR was determined.@*RESULTS@#BR ( vs. CR) had a higher sputum culture conversion rate and cure rate and prevented many premature deaths (decreased by 12.8%), thereby obtaining more quality-adjusted life years (QALYs) (increased by 2.31 years). The per capita cost in BR was as high as 138,000 yuan, roughly double that of CR. The ICER for BR was 33,700 yuan/QALY, which was lower than China's 1× per capita Gross Domestic Product (GDP) in 2020 (72,400 yuan).@*CONCLUSION@#BR is shown to be cost effective. When the unit price of Bedaquiline reaches or falls below 57.21 yuan per unit, BR is expected to be the dominant strategy in China over CR.

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 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
ObjectiveTo investigate the clinical efficacy of oral dydrogesterone alone for luteal phase support in natural cycle frozen-thawed embryo transfer （NC-FET）. MethodsThe clinical data of 1 530 NC-FET cycles enrolled in our Reproductive Center from January 2019 to September 2021 were retrospectively analyzed. According to different luteal support protocols， the patients were divided into oral dydrogesterone alone （group A， n=524）， vaginal progesterone soft capsules （group B， n=401） and vaginal progesterone soft capsules combined with dydrogesterone （group C， n=605）. The clinical outcomes and cost-effectiveness ratio were compared among the three groups. The primary outcome was live birth rate. ResultsThe live birth rate was 43.13% （226/524） in group A， 39.15% （157/401） in group B， and 42.64% （258/605） in group C. There was no statistical difference among the three groups （P > 0.05）. No statistical difference was observed in the HCG positive rate， implantation rate， biochemical pregnancy rate， clinical pregnancy rate， spontaneous miscarriage rate， ectopic pregnancy rate， twin delivery rate， premature delivery rate and newborn weight among the three groups （P>0.05）. Logistic regression analysis revealed that the three luteal support regimens did not affect live birth rate. Pharmacoeconomic analysis showed that taking group B as a reference， the cost increased by 19 227.30 yuan for every 1% increase in live birth rate in group A. ConclusionsIn NC-FET cycle， oral dydrogesterone alone can achieve the same clinical outcomes as vaginal progesterone soft capsules and vaginal progesterone soft capsules combined with dydrogesterone. Compared with that of progesterone soft capsules， the cost of oral dydrogesterone alone is increased， a large sample and multicenter prospective study is needed to further confirm our results.
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
Background & objectives: The World Health Organisation recommended immediate initiation of antiretroviral therapy (ART) in all adult human immunodeficiency virus (HIV) patients regardless of their CD4 cell count. This study was undertaken to ascertain the cost-effectiveness of implementation of these guidelines in India. Methods: A Markov model was developed to assess the lifetime costs and health outcomes of three scenarios for initiation of ART treatment at varying CD4 cell count <350/mm3, <500/mm3 and test and treat using health system perspective using life-time horizon. A few input parameters for this model namely, transition probabilities from one stage to another stage of HIV and incidence rates of TB were calculated from the data of Centre of Excellence for HIV treatment and care, Chandigarh; whereas, other parameters were obtained from the published literature. Total HIV-related deaths averted, HIV infections averted and incremental cost-effectiveness ratio per quality adjusted life years (QALYs) gained were calculated. Result: Test and treat intervention slowed down the progression of disease and averted 18,386 HIV-related deaths, over lifetime horizon. It also averted 16,105 new HIV infections and saved 343,172 QALYs as compared to the strategy of starting ART at CD4 cell count of 500/mm3. Incremental cost per QALY gained for the immediate initiation of ART as compared to ART at CD4 cell count of 500/mm3 and 350/mm3 was ? 46,599 and 80,050, respectively at reported rates of adherence to the therapy. Interpretation & conclusions: Immediate ART (test and treat) is highly cost-effective strategy over the past criteria of delayed therapy in India. Cost-effectiveness of this policy is largely because of reduction in the transmission of HIV
ABSTRACT
Resumen Objetivo: Identificar la intervención más costo-efectiva para el tratamiento de la diabetes mellitus tipo 2, en el primer nivel de atención, cuando el paciente requiere del uso de algún tipo de insulina, con base en estudios clínicos previos. Material y métodos: Se efectuó un análisis costo-efectividad desde la perspectiva del proveedor. Se obtuvieron los costos de tres tipos de insulina como fármaco de control: insulina glargina, insulina protamina neutra de Hagedorn (NPH) e insulina lispro/lispro protamina 25-75 UI. Los indicadores de efectividad se obtuvieron de estudios previos que analizaron el efecto de los fármacos sobre la hemoglobina glucosilada (HbA1c). Resultados: La intervención que presentó el mejor coeficiente costo- efectividad fue el tratamiento con insulina glargina, con un valor de 570, comparado con 643.1 de la insulina NPH y 572.6 de la insulina lispro/lispro protamina 25-75 UI. Conclusiones: La insulina glargina es el tratamiento en pacientes que requieren insulinas y no presentan daño microvascular, la que presenta la mejor evidencia para invertir debido a su costo y su efectividad (analizados a través del coeficiente costo-efectividad). Estos resultados pueden considerarse en el contexto mexicano para mejorar la adquisición de medicamentos y los estándares de tratamiento para pacientes con diabetes mellitus tipo 2.
Abstract Objective: To identify the best cost-effective intervention for the treatment of type 2 diabetes mellitus, at the first level of care, when the patient requires the use of insulin, based on previous clinical analysis. Materials and methods: A cost-effectiveness analysis was carried out, from the provider perspective. The cost of three types of insulin as a control drug were obtained: glargine insulin, neutral protamine Hagedorn (NPH) insulin and lispro insulin/lispro protamine 25-75 IU. The effectiveness indicators were obtained from previous studies that analyzed the effect on glycated hemoglobin (HbA1c). Results: The intervention that presented the best cost-effective coefficient was the treatment with glargine insulin, with a value of 570, compared to 643.1 for the NPH insulin and 57 for the lispro/lispro protamine insulin. Conclusions: Glargine insulin is the treatment in patients who require insulins, without microvascular damage, that presents the best evidence to invest in, because of its cost and efficiency (analyzed through a cost- efficiency coefficient). These results may be considered in the Mexican context to improve drug's acquisition and the treatment standards to treat type 2 diabetes mellitus.
