SWITCO 65+ was a prospective cohort study funded by the Swiss National Science Foundation (grant FN 33CSCO-122659). CTU Bern has been responsible for the data management and statistical analyses.
SWITCO 65+ was a prospective cohort study conducted in nine Swiss study centers. More than 1,000 in- and outpatients aged ≥65 years with acute venous thromboembolism were recruited between 2009 and 2012. Patients were followed up for 2 years. Data collection included data on health-care utilization, quality of life, and clinical outcomes. A large biobank was also part of the study. The cohort is a unique opportunity to study short- and long-term outcomes in elderly patients with venous thromboembolism.
CTU Bern was responsible to coordinate the set-up of the electronic data capturing system. The system integrated the clinical study database and the data management system of the biobank.
All main analyses have been done at CTU Bern.
