Worldwide, about 400 million major surgeries are performed annually. The scarce data available in the literature still suggest high postoperative morbidity and mortality, even in Europe. Data of the World Health Organization on causes of death suggest that death after surgery would be the number three cause of mortality if it were considered a separate cause of death. However, there is little structured or high-quality data on postoperative mortality in the literature.
The aim of this study project is to collect data on postoperative complications and mortalities worldwide and to establish a Perioperative Outcome Study Platform on this topic.
In the first study of this platform, we aim to investigate the association of hemodynamic characteristics with postoperative complications and mortality. It is a prospective, multi-center study.
In addition, the investigators aim to collect data on the structural characteristics of the study sites and, for each patient, characteristics of quality of perioperative care in order to analyze associations with hemodynamic characteristics and postoperative complications and mortalities.
