Cardiovascular diseases continue to be the leading cause of death worldwide. Among them, coronary artery disease has the greatest impact, being characterized as one of the main causes of death in Brazil over the last decade. One of the well-established treatments is coronary artery bypass grafting, which is the most performed among cardiac surgeries and, in our scenario, is primarily funded by the Unified Health System (SUS). The information obtained from the Paulista Registry of Cardiovascular Surgeries (REPLICCAR), in partnership with FAPESP, has been important for implementing improvements in the landscape of cardiac surgeries in the state of São Paulo. Although outcomes in cardiac surgery have improved due to the structuring and organization of quality programs, this is still not a reality at the national level. In a situation where data collection and quality initiatives play a central role in continuous improvement, generating value becomes essential for the sustainability of cardiac surgery programs. In this sense, the concept of Enhanced Recovery After Surgery (ERAS) has gained increasing traction. This concept is based on multidisciplinary protocols and scientific evidence, which help prepare patients for rapid recovery, resulting in reduced complications, shorter hospital stays, and, primarily, lower hospital costs. On the other hand, the increase in surgical waiting lists has also led to a rise in home mortality due to cardiac causes. Thus, among the various challenges imposed by the current scenario, the investigators believe that preparing patients for rapid recovery after coronary artery bypass grafting presents an opportunity for the sustainability of the healthcare system. Therefore, the aim of this project is to evaluate the impact of a technology platform based on ERAS on the postoperative recovery time of patients undergoing coronary artery bypass grafting in reference centers in the state of São Paulo, Timely Project - REPLICCAR III.
