National Study to Create a Russian Calculator for Postoperative Risks and Outcomes in Adults Undergoing Elective and Emergency Surgery

What this Trial Is About

Researchers are conducting a national multicenter observational study to develop a Russian national calculator for predicting the risk of postoperative complications and mortality. The study focuses on adult patients undergoing elective and emergency surgeries in various surgical fields including obstetrics, gynecology, urology, orthopedics, and more. The aim is to identify risk factors that lead to unfavorable postoperative outcomes and to create a comprehensive database for better understanding and prediction of surgical risks. The study includes two cohorts Cohort A will assess the incidence of primary outcomes such as 30-day mortality and complications, and Cohort B will identify risk factors and develop a risk calculator validated across different surgical specialties. Data collection involves filling out basic and additional checklists quarterly across centers to capture detailed surgical and postoperative information. The study period spans from 2024 to 2028 with monitoring of outcomes up to one year after surgery. Participants will be followed for various outcomes including 30-day and 90-day mortality and complications, length of stay in intensive care and hospital, multiple organ failure, ICU syndrome, readmission rates, and one-year mortality. Researchers will analyze long-term results and the influence of factors such as anesthesia type, urgency of surgery, age, comorbidities, and oncological conditions. The study is organized by the Russian Federation of Anesthesiologists and Reanimatologists and aims to improve postoperative care through validated risk assessment tools integrated into a national calculator.
