NCT05298540

Brief 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.

Outcome Measures

Primary Outcomes (8)

  • Recruitment rate

    Number of participants included from eligible patients; satisfactory recruitment defined as enrolment of ≥ 50% of eligible patients.

    6 months

  • Study retention

    Satisfactory retention rate ≥ 75% of participants completing the 8-week training programme

    6 months

  • Recruitment target

    The time required to meet the target recruitment of 30 patients

    6 months

  • Feasibility of testing procedures

    % of participants where outcome testing was completed

    6 months

  • Feasibility of data collection methods

    % of participants with complete data sets

    6 months

  • Adherence to the intervention: number of sessions

    Compliance to measure the feasibility of the study; the number of sessions completed out of the 40 planned sessions during the 8-week intervention

    6 months

  • Adherence to the intervention: total time

    Compliance to measure the feasibility of the study; the total time completed out of the planned 800 minutes during the 8-week intervention

    6 months

  • Acceptability, by participant report

    The theoretical framework of acceptability (TFA) questionnaire has been adapted to this study, in collaboration with one of the TFA development team, to evaluate participants' perceptions of the intervention. The questionnaire was designed to inductively evaluate the retrospective acceptability of the intervention. The seven-item questionnaire will provide a five-point Likert scale reporting method in relation to their agreement statements, where the minimum value is 5 and maximum value is 35, with a higher score indicating higher acceptability.

    measured after the 8 week intervention (ie 8-10 weeks)

Secondary Outcomes (1)

  • to estimate measures of precision about the mean and variance of cognitive outcome to inform sample size calculations for a subsequent efficacy study.

Study Arms (1)

Home-based computerised cognitive training

EXPERIMENTAL

Participants will be asked to complete 40 sessions (20 minutes / day, 5 days / week) of cognitive training over the 8-week intervention period (this will be assessed using automated data reports of user activity generated in collaboration with BrainHQ). Training will commence one week postoperatively to avoid the effects of sedatives, postoperative pain, sleep deprivation, and patient fatigue, and to improve adherence

Behavioral: Home-based computerised cognitive training with BrainHQ

Interventions

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.
