Based on limited published epidemiological data, up to an alarming 1 in 50 surgical inpatients die within 30 postoperative days. Based on our own data from the B-Unaware (NCT00281489) and BAG-RECALL (NCT00682825) clinical trials, 30-day postoperative mortality among high-risk surgical patients is comparable to this at Barnes-Jewish Hospital, and 1-year mortality among high-risk surgical patients may be as high as 10%. Short- and intermediate-term postoperative mortality is therefore a pressing public health concern. Similarly, postoperative major morbidity - including delirium, stroke, myocardial infarction, atrial fibrillation, blood clots, renal dysfunction, wound infection, pneumonia, respiratory failure, loss of functionality, and chronic pain - occurs commonly and affects a substantial proportion of surgical patients, critically ill patients and patients undergoing procedures for chronic pain. Many factors associate strongly and independently with postoperative mortality and major morbidity: patient age, functional status, comorbid medical conditions, and duration and invasiveness of surgery, among others. It is a strategic priority to identify pre- and intraoperative risk factors that are subject to modification.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
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.
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.
