ABSTRACT

ABSTRACT Purpose To evaluate the cost-utility of the iStent inject® for the treatment of mild-to-moderate open-angle glaucoma (OAG) within the Brazilian Unified Health System (SUS). Methods A Markov model was developed, in which the effectiveness outcome measure was the incremental cost-effectiveness ratio (ICER: R$ / QALY quality-adjusted life-year). Direct medical costs were obtained from the SUS perspective. The base case comprised of a hypothetical cohort of patients with OAG using topical medication and being managed according to the Clinical Protocol and Therapeutic Guidelines (PCDT) and a real-world setting based on data from Datasus. The model's robustness through sensitivity analyses was tested. Results In the PCDT base case setting, the trabecular micro-bypass implant provided gains of 0.47 QALYs and an ICER of R$7,996.66/QALY compared to treatment with topical medication. In the real-world setting based on data from Datasus, the trabecular micro-bypass implant, provided gains of 0.47 QALYs and an ICER of R$4,485.68/QALY compared to treatment with topical medication. The results were robust to sensitivity analyses. Conclusion Incorporating iStent inject® to SUS provides an improvement in the patient's quality of life with an additional cost that warrants the benefit provided to patients. Results may be considered cost-effective compared to topical medication.


RESUMO Objetivo Avaliar a relação custo-utilidade do iStent inject® para o tratamento do glaucoma de ângulo aberto leve a moderado no Sistema Único de Saúde. Métodos Foi desenvolvido um modelo de Markov, no qual a medida de resultado de efetividade foi a razão custo-efetividade incremental (razão de custo-efetividade incremental: R$/ano de vida ajustado pela qualidade). Os custos médicos diretos foram obtidos por meio da perspectiva do Sistema Único de Saúde. O caso base foi composto de uma coorte hipotética de pacientes com glaucoma de ângulo aberto em uso de medicação tópica tratados de acordo com o Protocolo Clínico e Diretrizes Terapêuticas e um cenário do mundo real baseado em dados do Departamento de Informática do Sistema Único de Saúde. Foi testada a robustez do modelo por meio de análises de sensibilidade. Resultados No cenário base do Protocolo Clínico e Diretrizes Terapêuticas, o implante trabecular micro-bypass proporcionou ganhos de 0,47 ano de vida ajustado pela qualidade e razão de custo-efetividade incremental de R$7.996,66/ano de vida ajustado pela qualidade em relação ao tratamento com medicação tópica. No cenário real baseado em dados do Departamento de Informática do Sistema Único de Saúde, o implante trabecular proporcionou ganhos de 0,47 ano de vida ajustado pela qualidade e razão de custo-efetividade incremental de R$ 4.485,68/ano de vida ajustado pela qualidade em relação ao tratamento com medicação tópica. Os resultados foram robustos para análises de sensibilidade. Conclusão A incorporação do iStent inject® ao Sistema Único de Saúde proporciona melhora na qualidade de vida do paciente com um custo adicional que garante o benefício proporcionado a eles. Os resultados podem ser considerados custo-efetivos em comparação com a medicação tópica.

ABSTRACT

AbstractBackground:Acute coronary syndrome (ACS) is defined as a “group of clinical symptoms compatible with acute myocardial ischemia”, representing the leading cause of death worldwide, with a high clinical and financial impact. In this sense, the development of economic studies assessing the costs related to the treatment of ACS should be considered.Objective:To evaluate costs and length of hospital stay between groups of patients treated for ACS undergoing angioplasty with or without stent implantation (stent+ / stent-), coronary artery bypass surgery (CABG) and treated only clinically (Clinical) from the perspective of the Brazilian Supplementary Health System (SHS).Methods:A retrospective analysis of medical claims of beneficiaries of health plans was performed considering hospitalization costs and length of hospital stay for management of patients undergoing different types of treatment for ACS, between Jan/2010 and Jun/2012.Results:The average costs per patient were R$ 18,261.77, R$ 30,611.07, R$ 37,454.94 and R$ 40,883.37 in the following groups: Clinical, stent-, stent+ and CABG, respectively. The average costs per day of hospitalization were R$ 1,987.03, R$ 4,024.72, R$ 6,033.40 and R$ 2,663.82, respectively. The average results for length of stay were 9.19 days, 7.61 days, 6.19 days and 15.20 days in these same groups. The differences were significant between all groups except Clinical and stent- and between stent + and CABG groups for cost analysis.Conclusion:Hospitalization costs of SCA are high in the Brazilian SHS, being significantly higher when interventional procedures are required.


Fundamento:Síndrome coronariana aguda (SCA) é definida como um “grupo de sintomas clínicos compatíveis com isquemia miocárdica aguda”, representando a principal causa de óbito no mundo, com elevado impacto clínico e financeiro. Nesse sentido, o desenvolvimento de estudos econômicos que avaliem os custos despendidos no tratamento da SCA deve ser considerado.Objetivo:Avaliar custos e tempo de internação hospitalar entre grupos de pacientes que trataram SCA, submetidos a procedimentos de angioplastia com ou sem implante de stent (stent+ / stent-), revascularização (Revasc) e tratados apenas clinicamente (Clínico), sob a perspectiva do sistema de saúde suplementar (SSS) brasileiro.Métodos:Realizou-se uma análise retrospectiva de contas médicas de beneficiários de planos de saúde considerando dados de custos de internação e tempo de permanência hospitalar para o manejo de pacientes submetidos a diferentes tipos de tratamento para SCA, no período entre 1/2010 e 6/2012.Resultados:Os custos médios por paciente foram de R$ 18.261,77, R$ 30.611,07, R$ 37.454,94 e R$ 40.883,37 nos grupos Clínico, stent-, stent+ e Revasc, respectivamente. Os custos médios por dia de internação foram de R$ 1.987,03, R$ 4.024,72, R$ 6.033,40 e R$ 2.663,82, respectivamente. Os tempos médios de internação foram de 9,19 dias, 7,61 dias, 6,19 dias e 15,20 dias nesses mesmos grupos. As diferenças foram estatisticamente significativas entre todos os grupos, exceto Clínico e stent- e entre os grupos stent + e Revasc, para a análise de custos.Conclusão:O custo hospitalar da SCA é elevado no SSS brasileiro e significativamente mais alto quando há a necessidade da realização de procedimentos intervencionistas.

ABSTRACT

IntroductionThe limitations of traditional ureteral stents in patients with deficiencies in ureteral drainage have resulted in frequent stent exchanges. The implementation of metallic stents was introduced to improve the patency rates of patients with chronic upper urinary tract obstruction, obviating the need for frequent stent exchanges. We report our clinical experiences with the use of metallic ureteral stents in the management of poor ureteral drainage.Materials and MethodsFifty patients underwent metallic ureteral stent placement from 2009 to 2012. Stent failure was defined as an unplanned stent exchange, need for nephrostomy tube placement, increasing hydronephrosis with stent in place, or an elevation in serum creatinine. Stent life was analyzed using the Kaplan-Meier methodology, as this was a time dependent continuous variable. A cost analysis was similarly conducted.ResultsA total of 97 metallic stents were placed among our cohort of patients: 63 in cases of malignant obstruction, 33 in the setting of cutaneous ureterostomies, and 1 in an ileal conduit urinary diversion. Overall, stent failure occurred in 8.2% of the stents placed. Median stent life was 288.4 days (95% CI: 277.4-321.2 days). The estimated annual cost for traditional polymer stents (exchanged every 90 days) was $9,648-$13,128, while the estimated cost for metallic stents was $4,211-$5,313.ConclusionOur results indicate that metallic ureteral stent placement is a technically feasible procedure with minimal complications and is well tolerated among patients. Metallic stents can be left in situ for longer durations and provide a significant financial benefit when compared to traditional polymer stents.

ABSTRACT

OBJECTIVES: The goal of this study was to perform an economic analysis of a primary stenting with drug-eluting stents (DES) compared with bare-metal stents (BMS) in patients with acute myocardial infarction (AMI) admitted through an emergency room (ER) visit in Korea using population-based data. METHODS: We employed a cost-minimization method using a decision analytic model with a two-year time period. Model probabilities and costs were obtained from a published systematic review and population-based data from which a retrospective database analysis of the national reimbursement database of Health Insurance Review and Assessment covering 2006 through 2010 was performed. Uncertainty was evaluated using one-way sensitivity analyses and probabilistic sensitivity analyses. RESULTS: Among 513 979 cases with AMI during 2007 and 2008, 24 742 cases underwent stenting procedures and 20 320 patients admitted through an ER visit with primary stenting were identified in the base model. The transition probabilities of DES-to-DES, DES-to-BMS, DES-to-coronary artery bypass graft, and DES-to-balloon were 59.7%, 0.6%, 4.3%, and 35.3%, respectively, among these patients. The average two-year costs of DES and BMS in 2011 Korean won were 11 065 528 won/person and 9 647 647 won/person, respectively. DES resulted in higher costs than BMS by 1 417 882 won/person. The model was highly sensitive to the probability and costs of having no revascularization. CONCLUSIONS: Primary stenting with BMS for AMI with an ER visit was shown to be a cost-saving procedure compared with DES in Korea. Caution is needed when applying this finding to patients with a higher level of severity in health status.

ABSTRACT

FUNDAMENTO: O Sistema Único de Saúde (SUS) estabelece que a angioplastia coronariana com o implante de duplo stent não deve exceder 20 por cento das angioplastias, resultando na necessidade de escalonar a maioria dos procedimentos nos pacientes com doença multiarterial. OBJETIVO: O objetivo do presente estudo foi avaliar os valores remunerados pelo SUS para a obtenção da revascularização miocárdica percutânea completa em pacientes do SUS com doença multiarterial relacionados ao número de procedimentos necessários e de stents implantados. MÉTODOS: Foram incluídos 141 pacientes com doença coronariana multiarterial, submetidos à revascularização completa com sucesso pelo implante de stent, com coronariografia aos 6 meses pós-implante. A revascularização completa foi definida como o tratamento percutâneo de todas as lesões com percentual de estenose > 70 por cento, em vasos com diâmetro > 2 mm. Para análise dos custos, foram considerados os valores da Tabela SIH/SUS de R$ 2.263,77 para o procedimento e R$ 2.034,23 por stent implantado. RESULTADOS: No período de 07/2006 a 12/2007 foram implantados 416 stents em 141 pacientes. A idade média foi de 59,7 ± 9,9 anos, com predomínio do sexo masculino (68,1 por cento). O número de vasos foi 356 e o número de lesões 416. Para a obtenção da revascularização completa pelo implante de stent coronáriano foi necessário o escalonamento em até 4 procedimentos. O tempo médio entre a 1ª e 2ª, 2ª e 3ª e 3ª e 4ª angioplastias foi de 45,8 ± 37,7, 55,4 ± 55,3 e 33,5 ± 19,1 dias, respectivamente. CONCLUSÃO: A revascularização percutânea completa em pacientes do SUS com doença coronariana multiarterial, realizada em sua grande maioria de forma escalonada, ocasiona considerável elevação de gastos públicos devido ao aumento do número de procedimentos.


BACKGROUND: The Brazilian Public Health System (SUS, acronym in Portuguese) establishes that coronary angioplasty with the double implant stent must not exceed 20 percent of the angioplasties, resulting in the need of assigning most of the procedures in patients with multiarterial disease. OBJECTIVE: The objective of the present study was to assess the paid values by the SUS in order to obtain the complete percutaneous myocardial revascularization in the SUS patients with the multiarterial disease, related to the number of necessary procedures and of implanted stents. METHODS: A total of 141 patients with multiarterial coronary disease, submitted to a successful complete revascularization, were included by the stent implant with coronariography in a 6-month period of post-implant. The complete revascularization was defined as the percutaneous treatment of all stenosis > 70 percent in vessels with diameter > 2 mm. For the costs analysis, the values from the Sistema de Informações Hospitalares (SIH) of the SUS table were considered as R$ 2,263.77, for the procedure; and R$ 2,034.23, per implanted stent. RESULTS: In the period from 7/2006 to 12/2007, 416 stents were implanted in 141 patients. The mean age was of 59.7 ± 9.9 years old, prevailing the male sex (68.1 percent). The number of vessels was 356 and the lesions number corresponded to 416. In order to obtain the complete revascularization by the coronary stent implant, it was necessary to stagger in up to four procedures. The mean time between the 1st and 2nd, 2nd and 3rd and 3rd and 4th angioplasties was of 45.8 ± 37.7; 55.4 ± 55.3 and 33.5 ± 19.1 days, respectively. CONCLUSION: The complete percutaneous revascularization in patients from the SUS with the multiarterial coronary disease, carried out in most of them staggered, causes considerable elevation of public expenses due to the increase of procedures' number.

ABSTRACT

Fundamentos: Os resultados tardios com os stents farmacológicos são melhores do que com stents convencionais, principalmente no que se refere à reestenose. Entretanto, no "mundo real", os stents farmacológicos são implantados em pacientes de maior complexidade, o que teoricamente já diminui a diferença dos resultados. Objetivos: Comparar resultados da utilização de stents com paclitaxel (Grupo I) em pacientes complexos com stents convencionais (Grupo II) implantados em pacientes menos graves. A partir dos resultados realizar análise para estimar a razão de custo-efetividade nos dois grupos. Métodos: Foram analisados 220 pacientes prospectivamente durante aproximadamente dois anos (média de 17 meses): 111 do Grupo 1 (GI) e 109 do Grupo II (GII). Foram avaliadas a sobrevida e a sobrevida livre de eventos através do método de Kaplan-Meier. Usando-se os critérios da Organização Mundial de Saúde, calculou-se a razão custo-efetividade incremental (RCEI) para cada reestenose evitada. O escore de propensão foi usado para reduzir diferenças entre os dois grupos. Resultados: Foi observado predomínio do sexo masculino nos dois grupos (n=174 66,8%), mas sem diferenças entre eles. Também não houve diferenças em relação à idade, que variou de 42 anos a 91 anos (65,9 anos). As diferenças que ocorreram, com maior incidência no GI foram: diabetes: GI=60 (50,4%) e GII=19 (17,4%), p=0,0001; história familiar para doença arterial coronariana (DAC): GI=43 (38,7%) e GII=24 (22,1%), p=0,007; infarto prévio: GI=54 (48,6%) e GII=31 (28,4%), p=0,002; cirurgia de revascularização prévia: GI=24 (21,7%) e GII=6 (5,5%), p=0,0005; angioplastia prévia: GI=28 (25,2%) e GII=17 (15,5%), p=0,077; síndromes coronarianas agudas: GI=48 (43,3%) e GII=35 (32,0%), p=0,088. Os pacientes triarteriais foram mais presentes no GI=21 (18,9%) do que no GII=11 (10,1%), p=0,029. No entanto, os pacientes do GII apresentaram mais frequentemente função normal do VE: GI=51 (45,9%) e GII=85 (77,9%), p=0,0001...


Background: Long term outcomes for drug eluting stents are better than those for bare metal stents, especially for restenosis. However, drug eluting stents are usually implanted in more complex patients, theoretically lessening the difference in the outcomes. Objetives: To compare the outcomes of paclitaxel stents (GI) in complex patients and bare metal stents (GII), in less complex patients. Methods: For some two years (mean: 17 months), 220 patients were analyzed prospectively: 111 in GI and 109 in GII. Their general survival and cardiovascular event-free survival rates were assessed through the Kaplan-Meier method. Using the criteria of the World Health Organization (WHO), the incremental cost-effectiveness ratio (ICER) was calculated for each restenosis avoided. Propensity scores was used to reduce selection bias by equating both groups based on these covariates. Results: Men predominated in both groups (n=174 66.8%), with no differences between them, including age, ranging from 42 to 91 years (65.9 years). The main differences, with higher rates in GI, were diabetes: GI=60 (50.4%) and GII=19 (17.4%), p=0.0001; family history: GI=43 (38.7%) and GII=24 (22.1%), p=0.007; previous acute myocardial infarction: GI=54 (48.6%) and GII=31 (28.4%), p=0.002; previous coronary artery bypass graft: GI=24 (21.7%) and GII=6 (5.5%), p=0.0005; previous angioplasty: GI=28 (25.2%) and GII=17 (15.5%), p=0.077; acute coronary syndrome: GI=48 (43.3%) and GII=35 (32.0%), p=0.088. Multivessel patients were more frequent in GI=21 (18.9%) than in GII=11 (10.1%), p=0.029. However, the GII patients presented normal left ventricle functions more frequently: GI=51 (45.9%) and GII=85 (77.9%), p=0.0001. There were no differences between the groups for the number of lesions treated and number of arteries per patient. The bare metal stent group presented simpler lesions: Type A GI=43 (25.6%); GII=65 (45.5%), p=0.0002; Type B: B1 GI=50 (29.7%) and GII=35 (24.5%), p=0.30...

ABSTRACT

OBJETIVOS: Comparar as relações de custo-efetividade do stent recoberto (SR) por rapamicina com o stent convencional (SC), sob duas perspectivas: medicina suplementar e sistema público (SUS). MÉTODOS: Modelo de decisão analítico com três estratégias de tratamento de lesão coronariana: intervenção coronária percutânea (icP) com SC; com SR com rapamicina e SC seguido de SR para manejo de reestenose sintomática. Os desfechos foram: sobrevida livre de eventos em um ano e expectativa de vida. As árvores de decisão foram construídas com resultados de registros e ensaios clínicos publicados. RESULTADOS: A sobrevida em um ano livre de reestenose foi de 92,7 por cento com SR e de 78,8 por cento com SC. A expectativa de vida estimada das estratégias foi muito semelhante, entre 18,5 e 19 anos. Sob a perspectiva não-pública, a diferença de custo no primeiro ano entre SC e SR foi de R$ 3.816, com relação de custo-efetividade incremental de R$ 27.403 por evento evitado em um ano. Sob a perspectiva do SUS, o custo por evento evitado em um ano foi de R$ 47.529. Na análise de sensibilidade, foram preditores relevantes a probabilidade de reestenose, a redução de risco esperada com SR, o custo do stent e o custo do manejo da reestenose. Os dados por anos de vida demonstraram relações de custo-efetividade bastante elevadas na simulação de Monte Carlo. CONCLUSÃO: As relações de custo-efetividade do SR por rapamicina foram elevadas em modelo brasileiro. O uso de SR foi mais favorável em pacientes de alto risco de reestenose, com elevado custo do manejo de reestenose e sob a perspectiva não-pública.


OBJECTIVES: To compare the cost-effectiveness ratios of sirolimus-eluting stents (SES) with bare-metal stents (BMS) under two perspectives: the "supplementary medical system" (health plans and private patients) and the public health (SUS) system. METHODS: A decision-analytic model using three different therapeutic strategies for coronary lesions: percutaneous coronary intervention (PCI) with BMS; with SES; or with BMS followed by SES to treat symptomatic restenosis. Study endpoints were one-year event-free survival and life expectancy. Decision trees were constructed using the results of published registries and clinical trials. RESULTS: One-year restenosis-free survival was 92.7 percent with SES and 78.8 percent with BMS. Estimated life expectancy was very similar for all the strategies, ranging from 18.5 to 19 years. Under a nonpublic perspective, the cost difference in the first year between BMS and SES was R$3,816, with an incremental cost-effectiveness ratio of R$27,403 per event avoided in one year. Under the SUS perspective, the cost per event avoided in one year was R$47,529. In the sensitivity analysis, probability of restenosis, risk reduction expected with SES, the price of the stent and cost of treating restenosis were all important predictors. In the Monte Carlo simulation, data per years of life saved showed very high cost-effectiveness ratios. CONCLUSION: In the Brazilian model, the cost-effectiveness ratios for SES were elevated. The use of SES was more favorable for patients with high risk of restenosis, as it is associated with elevated costs in restenosis management of and under a nonpublic perspective.

ABSTRACT

In recent years, remarkable therapeutic advances have been made in the field of interventional cardiology with the introduction of statins, thienopyridines, such as clopidogrel and drug-eluting stents. Only a small minority in developing countries can afford these new treatment modalities, while the public health system would be rapidly bankrupted if it were to provide these modalities for all patients who might benefit from it. The purpose of this review article is to provide insight regarding the cost-effectiveness of these new treatment strategies and to address the added costs resulting upon their adoption and their appropriateness in developing countries

ABSTRACT

Os autores revisam a evolução da intervenção coronariana percutânea, a sua crescente aplicação na revascularização miocárdica de pacientes portadores de doença arterial coronariana, seja no Brasil, seja no âmbito mundial. Desde a introdução do método, em 1977, com a utilização isolada do cateter-balão, a constatação de que o mesmo tinha limitações (oclusão aguda e reestenose), a adoção dos stents coronarianos e, mais recentemente, o advento dos stents farmacológicos, idealizados para reduzir ainda mais as taxas de reestenose, possibilitaram o crescimento exponencial da aplicação da intervenção coronariana percutânea (ICP) no Brasil, superando a cirurgia de revascularização e tornando-se o tratamento majoritário para enfermos sintomáticos, acometidos de aterosclerose obstrutiva coronariana. Esta preferência se salienta, a partir do ano 2000, após o início do reembolso dos stents pelo Sistema de Unico de Saúde Brasileiro. Este fato demonstra a importância do Sistema Público de Saúde, quando este incorpora os avanços médicos, e passa a oferecer bons padrões de tratamento cardiovascular a grande número de brasileiros. Destaca-se a complexidade da profilaxia da reestenose intra-stent, por sua ocorrência imprevisível e ubíqua. O controle deste fenômeno melhora a qualidade de vida, reduzindo o retorno da angina do peito, a realização de novos procedimentos de revascularização e a re-internação hospitalar. Os stents farmacológicos lograram êxito sólido e consistente na conquista deste objetivo de forma abrangente, beneficiando todas as apresentações clínicas e angiográficas, em maior ou menor grau. Sua adoção e critérios para sua utilização em outros países são discutidos, assim como a formalização das indicações preconizadas pela Sociedade Brasileira de Hemodinâmica e Cardiologia Intervencionista, para o seu reembolso pelo SUS. A incorporação de novas tecnologias em saúde é um processo que compreende duas etapas distintas: na primeira, o registro do produto é efetivado na Agência Nacional de Vigilância Sanitária (ANVISA)...


The authors review percutaneous coronary intervention (PCI) evolution and its growing application in myocardial revascularization for patients with coronary heart disease in Brazil and worldwide. PCI was introduced in 1977 using only the catheter balloon. Limitations of this method (acute occlusion and coronary restenosis) led to the adoption of coronary stents and more recently the advent of drug-eluting stents², which were developed to drastically reduce restenosis rates. These developments allowed the exponential growth of percutaneous coronary intervention (PCI) procedures in Brazil which have replaced many bypass surgery procedures and have become the gold standard for the majority of symptomatic patients suffering from coronary artery disease. The preference for this procedure gained new dimensions in 2000 when the Brazilian Public Healthcare System (SUS) began reimbursing for stent procedures. This measure exemplified the importance of the Public Healthcare System's participation in incorporating medical advances and offering a high standard of cardiovascular treatment to a large portion of the Brazilian population. It is emphasized that prevention of in-stent restenosis is complex due to its unpredictable and ubiquitous occurrence. Control of this condition improves quality of life and reduces the recurrence of angina pectoris, the need to perform new revascularization procedures and hospital readmissions. The overall success of the drug-eluting stents has proven to be reliable and consistent in overcoming restenosis and has some beneficial impact for all clinical and angiographic conditions. This paper discusses the adoption and criteria for the use of drug-eluting stents in other countries as well as the recommendations established by the Brazilian Society of Interventional Cardiology for their reimbursement by SUS. The incorporation of new healthcare technology involves two distinct stages. During the first stage, the product is registered with the National Health Surveillance Agency (ANVISA)...
