Perioperative Cognitive Trajectories in Deferred Surgery (CoTELE-SURGE)

Status Recruiting

Clinical Trial Summary

Cognition is the way people use their brains to think, understand, remember and make decisions. Cognitive changes are often seen even up to 1 year after surgery. Whether these changes are more than what is expected for someone's age and morbidities is still uncertain. Due to the COVID-19 emergency, many elective surgeries have been delayed, which is stressful for patients, but also represents an opportunity of understanding better how surgery can impact cognitive abilities. The purpose of this study is to explore if and how cognitive performance changes over time for patients aged 65 years or older, whose surgery has been postponed. due to the COVID-19 emergency, following and assessing the cognitive performance of these patients over time before and after surgery. In particular, in this study, the participant's cognitive performance will be assessed periodically with a computer-based instrument for cognitive testing, self-administered at home, in which tests are based on playing cards.

Clinical Trial Description

The primary objectives of the project are to describe perioperative cognitive trajectories of older patients whose elective noncardiac surgery has been deferred because of the COVID-19 emergency, and explore the intra-individual changes in these trajectories from before to after surgery, through periodic remote self-administered cognitive testing. Secondarily, in the same patients, the investigators will also describe the perioperative trajectories in depressive symptoms and pain, and study their correlation with the trajectories in cognitive performance. The study will be conducted remotely and virtually. The investigators will have an initial videoconference with the participant (and a support person if necessary) to explain the computerized cognitive test battery (i.e. the Cogstate Brief battery, CBB), and train on self-administration through a user-specific link. At each due assessment, the research team will call the participant to remind to complete the CBB; and to assess depressive symptoms, pain, and collect data on intercurrent clinical events (i.e. medication changes, hospitalization, ED or urgent care visits). ;

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.
