Introdução e objetivos: Estimar os rácios custo-efetividade e custo-utilidade da utilizac¸ão deticagrelor versus clopidogrel no tratamento de doentes com síndromas coronárias agudas(angina instável, enfarte do miocárdio sem elevac¸ão ST [NSTEMI] ou enfarte do miocárdio comelevac¸ão ST [STEMI]); incluindo doentes sujeitos a tratamento médico e aqueles geridoscom intervenção coronária percutânea (ICP) ou bypass aortocoronário com enxerto (CABG). Metodologia: Foi utilizada uma árvore de decisão de curto prazo e um modelo de Markov delongo prazo para simular a progressão dos doentes no decurso da sua vida. Os dados de eficácia clínica foram recolhidos a partir do ensaio clínico PLATO e os dados de consumo de recursos foram obtidos na Contabilidade Analítica do Hospital de Santa Marta, legislação dos GDH e consulta de bibliografia disponível. Resultados: Ticagrelor proporciona, a cada doente, um incremento de 0,1276 anos de vida e0,1106 QALY. Na perspectiva da sociedade, estes ganhos implicam um aumento da despesa em 610 D . Obtêm-se, assim, um custo incremental por ano de vida salvo de 4780 D e um custo incremental por QALY de 5517 D . Conclusões: Os resultados obtidos mostram que o ticagrelor diminui a quantidade de eventos,quando comparado com clopidogrel. Os custos com ticagrelor são parcialmente compensados por uma diminuição dos custos decorrentes dos eventos evitados. Assim, a utilização de ticagrelor na prática clínica portuguesa é custo-efetiva quando comparado com a abordagem com clopidogrel.
Introduction and Objectives To estimate the cost-effectiveness and cost-utility of ticagrelor in the treatment of patients with acute coronary syndromes (unstable angina or myocardial infarction with or without ST-segment elevation), including patients treated medically and those undergoing percutaneous coronary intervention or coronary artery bypass grafting. Methods A short-term decision tree and a long-term Markov model were used to simulate the evolution of patients' life-cycles. Clinical effectiveness data were collected from the PLATO trial and resource use data were obtained from the Hospital de Santa Marta database, disease-related group legislation and the literature. Results Ticagrelor provides increases of 0.1276 life years and 0.1106 quality-adjusted life years (QALYs) per patient. From a societal perspective these clinical gains entail an increase in expenditure of €610. Thus the incremental cost per life year saved is €4780 and the incremental cost per QALY is €5517. Conclusions The simulation results show that ticagrelor reduces events compared to clopidogrel. The costs of ticagrelor are partially offset by lower costs arising from events prevented. The use of ticagrelor in clinical practice is therefore cost-effective compared to generic clopidogrel.
