Effect of an mHealth self-help intervention on readmission after adult cardiac surgery: Protocol for a pilot randomized controlled trial

Aim To describe a protocol for the pilot phase of a trial designed to test the effect of an mHealth intervention on representation and readmission after adult cardiac surgery. Design A multisite, parallel group, pilot randomized controlled trial (ethics approval: HREC2020.331-RMH69278). Methods Adult patients scheduled to undergo elective cardiac surgery (coronary artery bypass grafting, valve surgery, or a combination of bypass grafting and valve surgery or aortic surgery) will be recruited from three metropolitan tertiary teaching hospitals. Patients allocated to the control group with receive usual care that is comprised of in-patient discharge education and local paper-based written discharge materials. Patients in the intervention group will be provided access to tailored 'GoShare' mHealth bundles preoperatively, in a week of hospital discharge and 30 days after surgery. The mHealth bundles are comprised of patient narrative videos, animations and links to reputable resources. Bundles can be accessed via a smartphone, tablet or computer. Bundles are evidence-based and designed to improve patient self-efficacy and self-management behaviours, and to empower people to have a more active role in their healthcare. Computer-generated permuted block randomization with an allocation ratio of 1:1 will be generated for each site. At the time of consent, and 30, 60 and 90 days after surgery quality of life and level of patient activation will be measured. In addition, rates of representation and readmission to hospital will be tracked and verified via data linkage 1 year after the date of surgery. Discussion Interventions using mHealth technologies have proven effectiveness for a range of cardiovascular conditions with limited testing in cardiac surgical populations. Impact This study provides an opportunity to improve patient outcome and experience for adults undergoing cardiac surgery by empowering patients as end-users with strategies for self-help.
