Implementation of Early Mobilization in Post-CABG Patients: A Constructivist Grounded Theory Study.

Purpose: Coronary artery bypass grafting (CABG) is an essential intervention for treating coronary artery disease. However, the effectiveness of postoperative rehabilitation often depends on the implementation of early mobilization by patients. In practice, adherence to early mobilization post-CABG is frequently suboptimal. This study focuses on patients who have successfully implemented early activity post-CABG, exploring the situational factors that facilitate early mobilization.

Patients And Methods: Semi-structured interviews were conducted with 15 post-CABG patients from three hospitals in Shanghai who had successfully implemented early mobilization. Data collection was conducted from October 1, 2024 to December 31, 2024. Utilizing a constructivist grounded theory approach, the interview guide was modified based on emerging themes throughout the study.

Results: Patients who successfully implement early mobilization typically undergo three main stages: intention, initiation, and maintenance. The study identified three main domains influencing these phases: Core Context (including the perception of the importance of exercise rehabilitation, understanding and beliefs about early mobilization, positive personal experiences with physical activity, and observing positive outcomes from others' activities); Essential Conditions (including physical condition, psychological preparedness, knowledge literacy, and initial outcomes); External Factors (including the atmosphere and promotion of early mobilization, the development of an exercise rehabilitation system from pre-surgery to ICU to ward, and social support).

Conclusion: This study provides a new perspective by examining the situational factors associated with the successful implementation of early mobilization after CABG. By focusing on successful cases, healthcare professionals can better understand the implementation process and experiences, enabling them to develop targeted interventions to improve adherence.
