Análise de custo-efetividade do reúso de cateteres de cinecoronariografia sob a perspectiva de uma instituição pública no Município do Rio de Janeiro, Brasil

O objetivo foi comparar a relação de custo-efetividade entre o uso de cateteres cardíacos novos com cateteres reprocessados sob a perspectiva de uma instituição pública federal. Foi elaborado um modelo analítico de decisão elaborado para estimar a razão de custo-efetividade entre duas estratégias de utilização de materiais para cateterismo cardíaco utilizando, como desfecho clínico, a ocorrência de reação pirogênica. Os custos foram estimados por coleta direta nos setores envolvidos e valorados em Real (R$) para o ano de 2012. A árvore de decisão foi construída com as probabilidades de pirogenia descritas em estudo clínico. O custo para o reúso foi de R$ 109,84, e, para cateteres novos, de R$283,43. A estratégia de reúso demonstrou ser custo-efetiva, e a razão de custo-efetividade incremental indicou que, para evitar um caso de pirogenia, serão gastos R$ 13.561,75. O estudo aponta o reúso de cateteres como uma estratégia de menor custo comparada ao uso exclusivo de cateteres novos e pode contribuir para a tomada de decisão dos gestores

Budget impact analysis of the percutaneous septal occluder for treatment of ostium secundum atrial septal defects in the Brazilian Unified National Health System

The aim of this study was to perform a budget impact analysis on the adoption of percutaneous occlusion of ostium secundum atrial septal defects in the Brazilian Unified National Health System. Costs were collected using micro-costing technique from medical records for each treatment technique (conventional surgery versus percutaneous septal occluder) at a public federal hospital specialized in high-complexity cardiology. The analysis showed that expenditures associated with percutaneous occlusion were lower than with conventional surgery, and sensitivity analysis confirmed the cost reduction in several scenarios, showing a significant budget impact with a 30% adoption rate for the percutaneous occluder (savings of approximately 1.5 million dollars per year). The study indicates that the adoption of the percutaneous septal occluder would mean cost savings of approximately 3.5 million dollars for the Brazilian public health system

Cost-Effectiveness of Procedures for Treatment of Ostium Secundum Atrial Septal Defects Occlusion Comparing Conventional Surgery and Septal Percutaneous Implant

<div><p>Objectives</p><p>The study performs a cost-effectiveness analysis of procedures for atrial septal defects occlusion, comparing conventional surgery to septal percutaneous implant.</p><p>Methods</p><p>A model of analytical decision was structured with symmetric branches to estimate cost-effectiveness ratio between the procedures. The decision tree model was based on evidences gathered through meta-analysis of literature, and validated by a panel of specialists. The lower number of surgical procedures performed for atrial septal defects occlusion at each branch was considered as the effectiveness outcome. Direct medical costs and probabilities for each event were inserted in the model using data available from Brazilian public sector database system and information extracted from the literature review, using micro-costing technique. Sensitivity analysis included price variations of percutaneous implant.</p><p>Results</p><p>The results obtained from the decision model demonstrated that the percutaneous implant was more cost effective in cost-effectiveness analysis at a cost of US$8,936.34 with a reduction in the probability of surgery occurrence in 93% of the cases. Probability of atrial septal communication occlusion and cost of the implant are the determinant factors of cost-effectiveness ratio.</p><p>Conclusions</p><p>The proposal of a decision model seeks to fill a void in the academic literature. The decision model proposed includes the outcomes that present major impact in relation to the overall costs of the procedure. The atrial septal defects occlusion using percutaneous implant reduces the physical and psychological distress to the patients in relation to the conventional surgery, which represent intangible costs in the context of economic evaluation.</p></div
