What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tests whether a structured communication protocol called StOP? helps surgical teams talk more clearly during operations. Researchers will compare death rates and other outcomes in 400 patients whose surgeons use the tool versus those who don't. The goal is to see if better teamwork can improve patient safety.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

400 people

The number who actually took part.

Started

Aug 2022

Finished

May 2026

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

For the clusters (surgeons) Inclusion Criteria: * Board-certified surgeons with specialization in one of the following disciplines: general, visceral, thoracic, vascular surgery, surgical urology, or gynecology. Exclusion Criteria: * Surgeons who are already performing StOP?-protocol. (Potentially, surgeons who took part in the first study (StOP-I) may still perform StOP?). * 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: 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: * 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
