ABSTRACT

Abstract Background: In multivessel disease patients with moderate stenosis, fractional flow reserve (FFR) allows the analysis of the lesions and guides treatment, and could contribute to the cost-effectiveness (CE) of non-pharmacological stents (NPS). Objectives: To evaluate CE and clinical impact of FFR-guided versus angiography-guided angioplasty (ANGIO) in multivessel patients using NPS. Methods: Multivessel disease patients were prospectively randomized to FFR or ANGIO groups during a 5 year-period and followed for < 12 months. Outcomes measures were major adverse cardiac events (MACE), restenosis and CE. Results: We studied 69 patients, 47 (68.1%) men, aged 62.0 ± 9.0 years, 34 (49.2%) in FFR group and 53 (50.7%) in ANGIO group, with stable angina or acute coronary syndrome. In FFR, there were 26 patients with biarterial disease (76.5%) and 8 (23.5%) with triarterial disease, and in ANGIO, 24 (68.6%) with biarterial and 11 (31.4%) with triarterial disease. Twelve MACEs were observed - 3 deaths: 2 (5.8%) in FFR and 1 (2.8%) in ANGIO, 9 (13.0%) angina: 4(11.7%) in FFR and 5(14.2%) in ANGIO, 6 restenosis: 2(5.8%) in FFR and 4 (11.4%) in ANGIO. Angiography detected 87(53.0%) lesions in FFR, 39(23.7%) with PCI and 48(29.3%) with medical treatment; and 77 (47.0%) lesions in ANGIO, all treated with angioplasty. Thirty-nine (33.3%) stents were registered in FFR (0.45 ± 0.50 stents/lesion) and 78 (1.05 ± 0.22 stents/lesion) in ANGIO (p = 0.0001), 51.4% greater in ANGIO than FFR. CE analysis revealed a cost of BRL 5,045.97 BRL 5,430.60 in ANGIO and FFR, respectively. The difference of effectiveness was of 1.82%. Conclusion: FFR reduced the number of lesions treated and stents, and the need for target-lesion revascularization, with a CE comparable with that of angiography.


Resumo Fundamentos: Em pacientes multiarteriais e lesões moderadas, a reserva de fluxo fracionada (FFR) avalia cada lesão e direciona o tratamento, podendo ser útil no custo-efetividade (CE) de implante de stents não farmacológicos (SNF). Objetivos: Avaliar CE e impacto clínico da angioplastia + FFR versus angioplastia + angiografia (ANGIO), em multiarteriais, utilizando SNF. Métodos: pacientes com doença multiarteriais foram randomizados prospectivamente durante ±5 anos para FFR ou ANGIO, e acompanhados por até 12 meses. Foram avaliados eventos cardíacos maiores (ECAM), reestenose e CE. Resultados: foram incluídos 69 pacientes, 47(68,1%) homens, 34(49,2%) no FFR e 35(50,7%) no ANGIO, idade 62,0 ± 9,0 anos, com angina estável e Síndrome Coronariana Aguda estabilizada. No FFR, havia 26 com doença (76,5%) biarterial e 8 (23,5%) triarterial, e no grupo ANGIO, 24(68,6%) biarteriais e 11(31,4%) triarteriais. Ocorreram 12(17,3%) ECAM - 3(4,3%) óbitos: 2(5,8%) no FFR e 1(2,8%) no ANGIO, 9(13,0%) anginas, 4(11,7%) no FFR e 5(14,2%) no ANGIO, 6 reestenoses: 2(5,8%) no FFR e 4 (11,4%) no ANGIO. Angiografia detectou 87(53,0%) lesões no FFR, 39(23,7%) com ICP e 48(29,3%) com tratamento clínico; e 77(47,0%) lesões no ANGIO, todas submetidas à angioplastia. Quanto aos stents, registrou-se 39(33,3%) (0,45 ± 0,50 stents/lesão) no FFR e 78(66,6%) (1,05 ± 0,22 stents/lesão) no ANGIO (p = 0,0001); ANGIO utilizou 51,4% a mais que o FFR. Análise de CE revelou um custo de R$5045,97 e R$5.430,60 nos grupos ANGIO e FFR, respectivamente. A diferença de efetividade foi 1,82%. Conclusões: FFR diminuiu o número de lesões tratadas e de stents e necessidade de revascularização do vaso-alvo, com CE comparável ao da angiografia.

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

FUNDAMENTO: Os gastos com cirurgia de revascularização do miocárdio (RVM) e angioplastia coronariana (AC), representaram importante ônus para o SUS. OBJETIVO: Analisar gastos do SUS com RVM e AC e sua performance nos hospitais do Estado do Rio de Janeiro (ERJ), de 1999 a 2008. MÉTODOS: As informações provieram das AIH pagas dos hospitais com mais de 100 revascularizações. As taxas de letalidade foram ajustadas por modelos Poisson (covariáveis idade, dias de permanência no hospital e gasto em UTI). Foram construídos índices de gasto médio relativo, dividindo-se o valor médio da fração de gasto em cada hospital pelo gasto médio no ERJ, em dólares. Para análise estatística empregou-se o Stata. RESULTADOS: Foram pagas 10.983 RVM e 19.661 AC em 20 hospitais nos 10 anos, com valores médios de US$ 3.088,12 e 2.183,93, respectivamente. A taxa de letalidade nas RVM flutuou de 9,2 por cento-1999 para 7,7 por cento-2008, com valores extremos de 5,0 por cento-9,2 por cento e nas AC de 1,6 por cento-1999 para 1,5 por cento-2008, com valores extremos de 0,9 por cento-2,3 por cento. Os hospitais diminuíram a realização de RVM e duplicaram a de AC. Idade, tempo de internação e gastos em UTI correlacionaram-se significativamente com a letalidade nas RVM e AC pagas no ERJ. Em média, os gastos com os serviços hospitalares representaram 41 por cento do total das RVM e 18 por cento das AC, e os com as órteses e próteses, 55 por cento das AC e 28 por cento nas RVM. CONCLUSÃO: Evidencia-se necessidade de melhorar a qualidade do atendimento das instituições que realizam RVM e AC pagas pelo SUS.


BACKGROUND: Expenses with coronary artery bypass grafting (CABG) surgery and coronary angioplasty (CA) represented a significant cost to SUS. OBJECTIVE: To analyze SUS expenses with CABG and CA and their performance in hospitals in the state of Rio de Janeiro (SRJ), from 1999 to 2008. METHODS: The information came from paid HAA in hospitals with more than 100 revascularization procedures. Mortality rates were adjusted by Poisson (with covariates age, length of hospital stay and ICU expenses). Mean relative cost indices were calculated by dividing the mean value of the cost fraction spent in each hospital by the mean expense in the SRJ in U.S. dollars. Stata software was used for statistical analysis. RESULTS: A total of 10,983 CABG and 19,661 CA were paid by SUS in 20 hospitals during the 10 years, with mean values of US$ 3,088.12 and 2,183.93, respectively. The mortality rate in CABG varied from 9.2 percent-1999 to 7.7 percent-2008, with ranges of 5.0 percent-9.2 percent and in CA, from 1.6 percent-1999 to 1.5 percent-2008, with ranges of 0.9 percent-2.3 percent. The hospitals decreased the number of CABG procedures and doubled CA procedures. Age, time of hospital stay and ICU costs significantly correlated with lethality in CABG and CA paid by SUS in the SRJ. On average, hospital service costs represented 41 percent of the total cost of CABG and 18 percent of CA, and with ortheses and prostheses, 55 percent in CA and 28 percent in CABG. CONCLUSION: It is clear the need to improve the quality of healthcare service in institutions that perform CABG and CA paid by SUS.

ABSTRACT

FUNDAMENTO: O Sistema Único de Saúde (SUS) realiza aproximadamente 80 por cento das intervenções coronarianas percutâneas (ICP) no Brasil. O conhecimento desses dados permitirá planejar adequadamente o tratamento da doença arterial coronariana (DAC). OBJETIVO: Analisar e discutir os resultados das ICP realizadas pelo SUS. MÉTODOS: Foram avaliados os dados do SIH/DATASUS disponibilizados para consulta pública. RESULTADOS: Entre os anos de 2005 a 2008 foram realizados 166.514 procedimentos em 180 hospitais. A mortalidade hospitalar média foi de 2,33 por cento, variando de 0 por cento a 11,35 por cento, sendo mais baixa no Sudeste, 2,03 por cento e mais alta na região Norte, 3,64 por cento (p < 0,001). A mortalidade foi de 2,33 por cento nos 45 (25 por cento) hospitais de maior volume, responsáveis por 101.218 (60,8 por cento) das ICP, 2,29 por cento nos 90 (50 por cento) de médio volume com 50.067 (34,9 por cento) ICP e 2,52 por cento nos 45 (25 por cento) de pequeno volume com 7.229 (4,3 por cento) ICP (p > 0,05). A mortalidade foi maior no gênero feminino (p < 0,0001), e nas idades > 65 a (p < 0,001). No diagnóstico de angina (79.324, 47,64 por cento) a mortalidade foi de 1,03 por cento e no de IAM (33.286, 32,30 por cento) 6,35 por cento (p < 0,0000001). No implante único de stent, o mais frequente (102.165, 61,36 por cento), a mortalidade foi de 1,20 por cento, e na ICP primária (27.125, 16,29 por cento), 6,96 por cento. CONCLUSÃO: Embora crescente, ainda é baixo o número de ICP no país. Os hospitais de grande volume, em menor número, foram responsáveis pela maior parte dos procedimentos. O implante único de stent por internação foi o procedimento reportado mais empregado. As mortalidades tiveram grande variabilidade entre os hospitais. A ICP primária foi a responsável pela maior taxa de mortalidade.


BACKGROUND: The Brazilian Public Health System (SUS) holds approximately 80 percent of percutaneous coronary interventions (PCI) in Brazil. Being aware of these data will enable to design a proper plan for the treatment of coronary artery disease (CAD). OBJECTIVE: To review and discuss the results of PCIs performed by the SUS. METHODS: We reviewed data from SIH/DATASUS available for public consultation. RESULTS: From 2005 to 2008, 166,514 procedures were performed in 180 hospitals. Average hospital mortality was 2.33 percent, ranging from 0 percent to 11.35 percent, being lower in the Southeast, 2.03 percent and higher in the northern region, 3.64 percent (p < 0.001). The mortality rate was 2.33 percent in 45 (25 percent) higher-volume hospitals, accounting for 101,218 (60.8 percent) of the PCIs, 2.29 percent in 90 (50 percent) medium-volume hospitals with 50,067 (34.9 percent) PCIs and 2.52 percent in 45 (25 percent) small-volume hospitals with 7,229 (4.3 percent) PCIs (p > 0.05). Mortality was higher in females (p < 0.0001) and at ages > 65 to = (p < 0.001). In the diagnosis of angina (79,324, 47.64 percent) mortality was 1.03 percent, and AMI (33,286, 32.30 percent) 6.35 percent (p < 0.0000001). In the single stent implantation, the most common (102,165, 61.36 percent), mortality was 1.20 percent, and primary PCI (27,125, 16.29 percent), 6.96 percent. CONCLUSION: Although it is growing, the number of PCIs in Brazil is still low. High-volume hospitals, in smaller numbers, accounted for most procedures. Single stent implantation through hospital admission was reported to be most commonly used procedure. Mortality rates were highly variable among the hospitals. Primary PCI was responsible for the highest mortality rate.

ABSTRACT

BACKGROUND: Acute coronary syndrome (ACS) is a major health care syndrome that can financially burden patients throughout the world, including Thailand. Few studies purposed estimating the costs of treatment. The data from the ACS registry database represented the costs of hospital charges paid by ACS patients. Although these were not the actual treatment costs, the authors can approximately estimate the total expenditure for the first admission. OBJECTIVES: First, calculate the cost of ACS to the patients, including diagnostic, demographic data, treatment modalities, type of payers, hospital profile, and outcomes. Second, find the appropriate model to identify the independent factors for predicting the treatment costs. MATERIAL AND METHOD: The present study collected data from the second and third phase of a national multicenter prospective registry of ACS in Thailand, Thai ACS registry (TACSR). 3,552 patients with new onset of ACS were analyzed. RESULTS: Median age was 67 years (range 26.5-105.5) with predominately male and median length of stay (LOS) was 7 days (range, 1-184). 42% referred from other hospitals. The median cost of the total population was 47,908 baht (range, 633-1,279,679). When classified into those of STEMI, NSTEMI, and UA, the costs were 82,848.5, 40,531 and 26,116 baht respectively, p < 0.0001. Patients in the government hospital had to pay the total cost with PCI and CABG, 152,081-161,374 baht and 203,139-223,747 baht respectively, while the private hospital charged almost twice as much. For the types of payers, private insurance including private employee security fund paid significantly more than others. Costs in patients paid by "30 baht na tional health scheme and social security fund" were significantly less than those of others. For modality of treatment in STEMI, primary PCI was significantly more costly than thrombolytics and no reperfusion therapy, 161,096.5 vs. 60,043.0 and 33,335.0 baht respectively p < 0.0001. Early invasive groups in NSTEMI/UA had much higher median costs 145,794.0 baht when compared to those of the conservative group, 47,908 baht, p < 0.0001. Two multiple linear regression models according to the diagnostic group identified the independent factors for predicting cost. PCI, LOS, CABG, admission in a private hospital, Death, GPIIb/IlIa inhibitors use, major bleeding, coronary angiogram, thrombolytics use, age and diabetes were independent predictors for the cost in STEMI patients, R2 = 0.58. For those of NSTEMI/UA, the independent predictors for the cost were PCI, LOS, CABG, admission in a private hospital, death, GP IIb/IIIa inhibitors use, major bleeding, coronary angiogram, age, ventricular arrhythmia, CHF and referred patients, R2 =0.62. CONCLUSION: Costs in ACS patients were markedly different among diagnostic groups. The clinical risk factors were hospital type, type of payers, referred system, treatment procedures, drugs used and complications including outcome. Some of these factors could independently predict the costs.

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.
