RESUMO
Background: Cerebrovascular accidents (CVI) are considered the second most serious complication in cardiac surgery patients with a frequency of 10%. By preventing complications of surgical treatment, using a Color Doppler ultrasound (CDU) device, in the population of cardiac surgery patients, the unplanned costs of prolonged postoperative treatment would be reduced. Objective: To prove that the acquisition and use of the newly developed CDU device "Affinit 30" is completely economical, profitable and medically justified. Methods: Numerical parameters of the treatment of cardiovascular patients were analyzed (number of procedures, number of days in the intensive care unit, cost of additional consultative services of the clinic for radiology and neurology), and the calculated economic value of the potential investment, as well as the cost of preventing surgical complications, by purchasing and installing a new modern CDU device. Results: The profitability of the investment was assessed using the economic parameters Net Present Value (NPV) of the investment, Internal rate of return (IRR) and Profitability Index (PI). A mathematical calculation with the given parameters yields NPV = 948,850 KM and IRR of 273% when applied to the given parameters. The PI value is 12.6, which matches the previously calculated NPV and IRR values. Conclusion: The acquisition and use of the newly developed CDU device "Affinit 30" is economically profitable and medically justified. This is shown by the calculated values of the economic parameters Net Present Value of the investment (NPV), Internal rate of return (IRR) and the Profitability Index (PI).
