Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To test the impact of the StOP?-protocol on patient outcomes, the study is designed as a randomized controlled trial. Surgeons will be randomized either (a) in the intervention group and be trained to perform the StOP?-protocol or (b) in the control group and will communicate as they prefer during their operations. Post-operative patient outcomes of the surgeons in the intervention and the control group will be compared to evaluate the effects of the StOP?-protocol.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Interventional group
The surgeons will undergo a multi-module training on how to use the StOP?-protocol and perform the StOP?-protocol during all their operations during a 4-month period.
StOP?-protocol
The StOP?-protocol is an intra-operative briefing initiated by the responsible surgeon. When performing a StOP?-protocol, the surgeons inform the team present in the operating room about the Status (St) of the operation, the Objectives (O) of the operations, the potential problems (P) they may meet and encourage the team to ask questions or voice concerns (?). The responsible surgeon announces at the team timeout when they plan to perform the StOP-protocol(s).
Control group
Surgeons in the control group will not be trained to the StOP?-protocol and will communicate as usual during their operations.
No interventions assigned to this group

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients operated by cluster surgeons during the cluster-specific time period
* General consent from the patients, allowing the use of healthcare-related data that are the result of the patient's treatment. In case no written document from the general consent is available despite documented efforts of the participating center, article 34 HRA (Swiss law) will be applied, allowing the use of the healthcare-related patient data.
Exclusion Criteria
* Surgeon who were previously enrolled in the StOP?-II trial (this is relevant for surgeons who move or rotate between departments/hospitals and might therefore be working at different participating sites).
For the patients:
* Patient age below 18 years
* Previous operation at the same site up to 30 days prior the index operation
* Procedures not done in operating rooms but in outpatient clinics, on wards, etc.
* Mainly diagnostic endoscopic procedures (e.g. colonoscopy, gastroscopy, bronchoscopy)
* Percutaneous interventions (e.g., transurethral interventions)
* Documented refusal for the use of healthcare related data
