What this trial studies

This observational study aims to identify risk factors associated with unfavorable postoperative outcomes by creating a national database of surgical patients in Russia. It will involve a multicenter approach, collecting data from adult patients undergoing both elective and emergency surgeries across various specialties. The study seeks to develop a risk calculator for postoperative complications and mortality, enhancing the understanding of predictors that contribute to adverse outcomes. By analyzing a comprehensive dataset, the study aims to improve patient safety and surgical practices.

Why it matters

Potential benefit: If successful, this study could lead to improved identification of high-risk patients and better management of surgical outcomes.

How similar studies have gone: Previous international and national registries have shown success in identifying risk factors and improving surgical outcomes, indicating that this approach is supported by existing literature.
