[Cost-effectiveness analysis on the reutilization of coronary artery catheters in a public hospital in Rio de Janeiro, Brazil].

The aim of this study was to compare the cost-effectiveness ratio of new versus reprocessed coronary artery catheters in a Federal public hospital. This was an analytical decision-making model prepared to estimate the cost-effectiveness ratio between two strategies in the use of materials in coronary artery catheterization, with pyrogenic reaction as the clinical outcome. Costs were estimated using direct data collection in the respective catheterization services and expressed in Brazilian Reais (R$), with 2012 as the reference year. The decision-making tree was constructed with the probabilities of pyrogenic reaction as described in a clinical trial. The cost per catheter for reuse was R$ 109.84, as compared to R$ 283.43 for a new catheter. The reutilization strategy proved to be cost cost-effective, and the incremental cost-effectiveness ratio indicated that R$ 13,561.75 would be spent to avoid one case of pyrogenic reaction. The study identified reuse of coronary artery catheters as a lower cost strategy compared to the exclusive use of new catheters, thus potentially assisting decision-making by health administrators.
