Study of health results around surgery

This study collects information about anesthesia and care around surgery (a “registry”). By joining, you help researchers understand what care is used and how patients do, without necessarily receiving a new treatment.

This study follows people after planned, higher-risk surgery to learn what complications happen and how patients do long-term. It may help doctors predict risks and improve care for people having similar operations.

This study follows patients who have had major surgery to track what problems may develop afterward and how often they occur. Understanding these complications helps doctors improve care and patient safety.

This study looks at patients who've had major abdominal, bone, or blood-vessel surgery to understand what factors make some people more likely to have complications afterward. It analyzes information already collected from hospitals to help doctors better predict and prevent problems.

This study is looking at how common complications are after surgery around the world. It wants to include many different types of surgeries and patients, to better understand and improve surgical safety.

This study looks at how pediatric patients do after different types of planned and unplanned surgeries at participating hospitals. It may help doctors improve care and safety for children undergoing surgery.
