Russian Registry of Surgical OutcomeS

Plain-language summary

Identification of risk factors that cause a high probability of an unfavorable outcome in the postoperative period is an urgent problem. The creation of national databases (registries) makes it possible to maximally cover a certain patient population by identifying its characteristic risk predictors. As literature data show, existing registries differ in the criteria for inclusion in the study, in the characteristics of the populations studied, and there is often no common view on the classification of postoperative outcomes. Goal of a study is a creation of a Russian national calculator for the risk of postoperative complications and mortality. Two-level observational retrospective-prospective study was planned. Setting: National multicenter study of surgical inpatients. Patients: Adult patients undergoing elective and emergency surgery. Types of interventions: in obstetrics, in gynecology, on the breast, in urology and kidneys, in endocrine surgery, in maxillofacial surgery, in orthopedics and traumatology, on the lower floor of the abdominal cavity, on the liver and biliary tract, on the upper floor of the abdominal cavity cavities, in thoracic surgery, in vascular surgery, in neurosurgery, in cardiac surgery, in other areas (with mandatory specification). The study was organized by the Federation of Anesthesiologists and Reanimatologists of Russia. Primary (30-day mortality, 30-day complications) and secondary (hospital mortality, hospital complications, length of stay in anesthesiology, resuscitation and intensive care departments, length of hospital stay, multiple organ failure (2 or more points on the SOFA scale (Sequential)) Organ Failure Assessment), 90-day mortality, 90-day complications, intensive care after-effects syndrome, readmission, 1-year mortality) outcomes were determined. The required sample size and statistical analysis methods are described. The planned duration of the study is 2024-2028.
