Feasibility Study of Preoperative Cognitive Training in Cardiac Surgical Patients (Cog-Train)
2017年11月29日 更新者：Papworth Hospital NHS Foundation Trust
The Cog-Train Feasibility Study: a Single-arm Trial Investigating the Feasibility of a Preoperative Cognitive Training Intervention (Cog-Train) in Cardiac Surgical Patients
The purpose of this study is to evaluate the feasibility of administering a 20-day preoperative cognitive training intervention (Cog-Train) to a widely inclusive sample of cardiac surgical patients.
研究概览
详细说明
Cognitive outcomes remain poor after cardiac surgery.
Data from the field of cognitive neuroscience suggests that cognitive training, which harnesses the brain's adaptive plasticity to improve, maintain, or restore function in a target area, can be used to strengthen brain resilience and improve cognitive outcomes following challenge.
While its effectiveness has been demonstrated in older adults as well as in other (nonsurgical) patient populations, no training intervention like this has ever before been used in any surgical patient in the preoperative period.
The purpose of this study is to evaluate the feasibility of administering a 20-day cognitive training intervention (Cog-Train) to a widely inclusive sample of cardiac surgical patients before their surgery.
Data obtained will be used to design a full-scale randomised controlled trial (RCT) on Cog-Train's effectiveness in improving postoperative cognitive outcomes.

实验性的：Cog-Train Intervention
|
Twenty-one days prior to surgery, patients will begin self-administering the intervention using an iPad tablet.
This intervention will consist with daily sessions of at least 20 minutes of the Cog-Train task (the task and regimen used to obtain robust effects in previous studies by members of our group).
Cog-Train is an n-back task - an adaptive working memory computer game that extends players' working memory capacity by getting progressively more difficult as the player's performance increases.
