About

This is a prospective, randomized controlled trial to evaluate the effectiveness of a Technology-Enhanced Continuous Nursing System (TECNS) compared to routine care for patients after coronary artery bypass grafting (CABG). The study aims to determine if the TECNS intervention, which includes digital health tools, personalized tele-rehabilitation, and continuous nursing support, can improve clinical outcomes such as postoperative hemoglobin recovery, reduce long-term major adverse cardiac events (MACE), and enhance patients' quality of life and psychological well-being.

Full description

Patients undergoing coronary artery bypass grafting (CABG) face significant challenges during the post-discharge recovery period. The transition from hospital to home often creates a "care gap," where insufficient support and follow-up can lead to suboptimal outcomes, including poor medication adherence, increased complication rates, and diminished quality of life. This study was designed to address this gap by implementing and evaluating a Technology-Enhanced Continuous Nursing System (TECNS). Participants were randomized to receive either the comprehensive TECNS intervention for 6 months post-discharge or standard routine care. The TECNS intervention integrated a dedicated smartphone application for education, a WeChat group for peer and professional support, personalized tele-rehabilitation plans delivered by nurses, and coordination with community health centers. The study hypothesized that this proactive, continuous care model would lead to superior physiological recovery, better long-term clinical outcomes, and improved patient-reported outcomes compared to the traditional, fragmented approach to post-discharge care.

358 participants in 2 patient groups

Experimental: Technology-Enhanced Continuous Nursing System (TECNS) Group

Experimental group

Description:

Patients received a comprehensive, 6-month continuous nursing program post-discharge. This included training on a dedicated smartphone app for educational modules; access to a moderated WeChat group for peer support and health tips; scheduled tele-rehabilitation calls from cardiac nurses for monitoring, education, and personalized guidance; and coordination with community health centers for follow-up. This was in addition to standard in-hospital care.

Treatment:

Behavioral: Technology-Enhanced Continuous Nursing System

Active Comparator: Routine Care Group

Active Comparator group

Description:

Patients received standard institutional postoperative care, including basic discharge education (oral and written summaries on medication, diet, and activity). Post-discharge care consisted of scheduled outpatient follow-up visits at 1 and 3 months post-surgery, without the technology-enhanced continuous support components.

Treatment:

Behavioral: Routine Postoperative Care
