Intra- and postoperative adverse events (iAEs and pAEs) occur in up to one third of all patients undergoing surgery. They are devastating to patients and costly to health care systems. Their number tends to increase due to the rising complexity of both the patient's risk profile and the surgical procedure. Postoperative deaths have been identified to be the third most frequent cause of death worldwide. Teamwork in surgery has been attributed to have a potentially great impact on avoiding postoperative morbidity. Up to 50% of all adverse in-hospital events were rated to be potentially preventable. However, their prevention typically requires a change in systems and individual behaviour. Standardised assessments of iAEs and pAEs are a prerequisite to develop and define strategies for prevention of AEs. While awareness of pAEs has highly risen through the introduction of the Clavien-Dindo classification, the most widely used classification for grading severity of pAEs, the relevance of transparent monitoring of iAEs is still highly undervalued.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
\- All in-hospital patients (consecutive or random sample) undergoing surgery from general surgery, vascular, surgery, orthopaedics/traumatology and urology in the operating room with anaesthesia involvement
Exclusion Criteria:
* Patients undergoing one-day-surgery (with or without anaesthesia-involvement)
* Procedures without anaesthesia-involvement (in- or out-patient)
* ASA risk classification (ASA) VI patients (brain-death, organ-donor)
* Follow-up procedure of a patient already included in the study
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
