INTRODUCTION: Perioperative risk refers to the likelihood of adverse events occurring during and after surgery. For the purpose of defining and classifying adverse events and predicting them, a comprehensive search of Pubmed and Lens.org was made according to the author expert opinion. OBSERVATIONS: Traditionally, two main types of postoperative adverse events have been investigated: complications and mortality. However, over the past decade, there has been a growing trend to expand the range of adverse events analyzed, from intraoperative critical events and the quality of recovery from anesthesia to the development of intensive care syndrome, assessing quality of life, disability, and survival over time. An important aspect associated with adverse events and outcomes is the provision of additional resources for a long-term stay for patients with acute respiratory viral infections and inpatient care after discharge, among other things. The review formulates its own concept of perioperative risk, based on a critical analysis of literature, with an emphasis on the need to create an ideal tool, such as a calculator, that must undergo external validation. This tool should include available, modifiable variables, and accurately determine the full range of adverse events and outcomes during the intra- and early postoperative periods, as well as delayed events. The concept shall also focus on identifying and characterizing patients with a high risk of perioperative complications.
