Summary

The aims of this study are to (1) evaluate the feasibility and acceptability of a home-based computerised cognitive training programme in the postoperative cardiac surgical population, and (2) estimate measures of precision about the mean and variance of cognitive outcome to inform sample size calculations for a subsequent efficacy study.

Detailed description

Heart surgery is a common procedure for coronary heart disease (blocked or narrowed coronary arteries) and valve problems (narrowing or hardening of the heart valves). It is known that after surgery some patients experience problems with their 'cognitive health' - this includes aspects like memory problems, concentration, and attention. These cognitive health problems can last for several months and can have a considerable impact on patients, and their family. Cognitive training (which means exercising the brain) has been shown to improve cognitive health in a number of patient groups including healthy older adults, patients with heart failure, and patients with mild cognitive impairment. The aim of this study is to find out if home-based computerised cognitive training (CCT) improves cognitive health after heart surgery. Investigators will recruit adult (≥ 18 years) patients undergoing first time elective cardiac surgery, who are willing to engage with an online training programme, and due to the nature of the intervention, potential participants must have access to a computer or tablet and access to the internet. Before surgery, a brief cognitive assessment will be carried out. Participants will be asked to complete 20 minutes of cognitive training exercises, 5 days per week, starting one week after their operation. A member of the research team will contact the patient once a week to check progress, to provide support, and to help with any technical issues. After the 8-week CCT (brain training exercises) programme, a follow-up video call will be arranged. During this follow-up participants will complete a second cognitive assessment and a questionnaire to see how acceptable and helpful they found the brain training exercises.

Type	Name	Description
BEHAVIORAL	Home-based computerised cognitive training with BrainHQ	Participants will be registered for individual accounts to an online CCT program created by BrainHQ (Posit Science, San Francisco), that can be administered using their own computer or tablet. BrainHQ has been associated with improvements in memory, attention, and processing speed. The program will be customised to target domains thought to be deficient in the postoperative period and will include training in memory, attention, and processing speed. Specifically, the following six games have been selected: hear, hear (auditory memory and attention), to-do list training (working memory), divided attention (attention), target tracker (attention), double decision (useful field of view and visual processing speed), and eye for detail (visual processing speed and visual working memory). The exercises are adaptive, adjusting the application difficulty to the participants performance.
