The Inselspital Surgical Cohort Study

Status Active, not recruiting

Clinical Trial Summary

Personalizing surgical care is of enormous clinical relevance, when considering the number of patients undergoing surgery in Switzerland every year. Currently, personalization is based on underlying or coexisting disease or alterations of laboratory values, but there is no accepted biological test available that may predict success or failure of surgery. Surgical site infections are the most common form of hospital-acquired infections. While the relevance of bacteria, antibiotics and intensive care support is well accepted, the impact of the individual host response remains poorly understood. The Investigators hypothesize that postoperative alterations of the metabolome allow identification of predictors of surgical complications in general, and surgical site infections in particular.

Clinical Trial Description

The investigators will conduct a prospective cohort study aiming to identify the metabolic and genetic signature that is associated with surgical site infections. Secondary aims and outcomes include the influence of metabolome on response to anesthetic drugs and acute and chronic pain, surgery- and anesthesia-factors related to short- and long-term oncological outcome, metabolic response effect on infectious complications and rejection after transplantation, bacteria-specific immune responses to major surgery after 2-4 weeks after surgery, metabolomics and macrobiotic markers for postoperative ileus or anastomotic leakage, and the effect of the presence of multidrug resistant bacteria on surgical outcome. All patients undergoing surgery in the investigators' clinic and who gave informed consent will be included. A blood sample will be taken before surgery, on the first postoperative day and after 3-8 weeks. A Urine sample will be taken after surgery and after 3-8 weeks. Sink and rectal swabs will be acquired before surgery. The samples will be stored in a Biobank. Additionally, all data routinely captured during the treatment of the patient from the different data collection systems in use in the investigators' hospital will be coded and centralized in a single, cohort database ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
