The effectiveness of a nurse-led home-based cardiac rehabilitation based on instant information intervention in the prognosis of patients with TAVR: A randomized controlled trial protocol.

BACKGROUND

Patients with poor prognosis after TAVR surgery require high-quality cardiac rehabilitation. Digital home-based rehabilitation based on real-time information intervention can improve outcomes. However, the parameters of the text message intervention, such as text message content, intervention duration, text message frequency, and other parameters, may vary.

METHODS

This is an evaluator-blinded randomized controlled trial. TAVR patients will be recruited from the cardiology intensive care unit of a hospital and randomly assigned to either the control group or the experimental group. The control group will receive standard cardiac rehabilitation, while the experimental group will receive instant message rehabilitation intervention over six months in addition to the standard care. The primary outcomes are home-based cardiac rehabilitation adherence and six-minute walk distance. Secondary outcomes include quality of life, frailty, activities of daily living scale scores, incidence of adverse events, death during follow-up, NYHA functional classification, readmission rate, and length of hospital stay. Data will be collected at three time points: baseline, three months after intervention, and six months after intervention. Generalized equation assessment will be used to evaluate the effectiveness of the instant message intervention.

DISCUSSION

Using behavior change theory as the overall framework, guided by behavior change techniques and based on evidence-based medicine, the digital HBCR intervention program that can be implemented by caregivers has been designed. If the intervention proves effective, it will promote the development of home-based rehabilitation for TAVR patients.
