NCT03009929

Brief Summary

Whereas there are several validated systems for reporting postoperative complications, there are only a few and not prospectively validated systems for reporting intraoperative complications. The investigators developed a definition and CLASSification for Intraoperative Complications CLASSIC within a Delphi study involving international interdisciplinary experts. As both surgery and anaesthesia may be involved in complications in the perioperative period, all patient-related intraoperative complications occurring between skin incision and closure are considered in this reporting system. CLASSIC was updated to ClassIntra® v1·0, by encompassing five severity grades to align with the validated Clavien-Dindo Classification for grading postoperative complications. The aim of this international multicentre observational cohort study is to assess the validity and practicability of this newly derived and updated classification system ClassIntra® in patient undergoing an in-hospital surgical procedure. Providing an easy applicable and internationally validated classification system is a contribution to improve quality of health care and patient safety.

    From after surgery up to hospital discharge, timeframe up to 30 days

  • Duration of surgery

    From start to the end of the surgical procedure

  • Complexity of main surgical procedure

    Baseline

  • in-hospital mortality

    From after surgery up to hospital discharge, timeframe up to 30 days

  • 30-day mortality

    30 days postoperatively

  • +1 more secondary outcomes
