From Prehabilitation to Rehabilitation (Prehab2Rehab): Digitally Supported Short-Term Prehabilitation Prior to Cardiac Surgery (Prehab2Rehab)

23 июля 2026 г. обновлено: Ludwig Boltzmann Institute for Digital Health and Prevention

From Prehabilitation to Rehabilitation (Prehab2Rehab): Digitally Supported Short-Term Prehabilitation Prior to Cardiac Surgery - A Prospective Observational Feasibility Trial

Prehab2Rehab is a prospective single-arm feasibility study evaluating the implementation of a multimodal, digitally supported prehabilitation program for adults awaiting elective cardiac surgery. During the routine preoperative waiting period, participants receive individualized education, psychosocial support, nutritional counselling, home-based physical activity guidance, and digital self-management support. The study aims to determine the feasibility, acceptability, usability, and safety of integrating this multidisciplinary prehabilitation pathway into routine clinical care. Exploratory outcomes include functional capacity, psychological well-being, nutritional status, digital engagement, and selected perioperative clinical outcomes to inform the design of future confirmatory trials.

Подробное описание

Background

Patients awaiting elective cardiac surgery frequently experience reduced physical capacity, psychological distress, and modifiable lifestyle-related risk factors that may negatively influence perioperative recovery. While advances in cardiac surgery have substantially improved survival, optimizing patients' physical and psychological condition before surgery has become an increasingly important component of perioperative care.

Multimodal prehabilitation has shown promising results in several surgical populations by combining exercise, nutritional support, psychological interventions, and patient education. However, structured prehabilitation programs are not routinely implemented in Austria because of organizational, logistical, and resource-related barriers. Digital health technologies provide an opportunity to integrate multidisciplinary prehabilitation into existing clinical pathways while minimizing disruption to routine care.

The Prehab2Rehab project was developed to establish an integrated, digitally supported care pathway that connects the preoperative waiting period with postoperative rehabilitation. Rather than replacing routine care, the intervention complements existing clinical services by providing structured support before surgery and facilitating patient engagement throughout the perioperative pathway.

Study Design

This prospective, single-arm observational feasibility study will be conducted at the Vienna General Hospital (Medical University of Vienna). Approximately 40 adults scheduled for elective low-risk cardiac surgery (NYHA class I-II) will participate in a multimodal prehabilitation program delivered during the routine preoperative waiting period of approximately 6-10 weeks.

The primary objective is to evaluate the feasibility of implementing the intervention in routine clinical practice. Feasibility outcomes include recruitment and retention, adherence to intervention components, completeness of data collection, usability and acceptability of the digital support tools, and intervention safety.

Secondary exploratory analyses will estimate within-group changes in functional performance, psychological well-being, nutritional status, health-related quality of life, and selected perioperative clinical outcomes. These data will be used to estimate effect sizes and inform the design of future randomized controlled trials.

Intervention

The Prehab2Rehab intervention is a personalized, multimodal prehabilitation program integrated into routine perioperative care. It includes:

structured patient education regarding surgery, recovery, and self-management, psychosocial support focusing on stress management, coping strategies, motivation, and self-efficacy, nutritional assessment and individualized nutritional counselling, individualized home-based physical activity guidance, including aerobic exercise, resistance exercises, breathing exercises, and inspiratory muscle training, digital support for education, communication, activity documentation, and care coordination through study-specific digital platforms.

The intervention is individualized according to participants' clinical status and preferences and is delivered by a multidisciplinary team including physicians, psychologists, dietitians, physiotherapists/sports scientists, and study staff. Participation in the study does not alter routine surgical management or postoperative rehabilitation.

Assessments

Participants are assessed at baseline before prehabilitation, immediately before surgery, and after completion of structured Phase II cardiac rehabilitation. Assessments include measures of functional capacity, nutritional status, patient-reported outcomes, digital engagement, intervention adherence, safety, and routinely collected perioperative clinical outcomes. In addition, semi-structured qualitative interviews with patients and healthcare professionals will explore acceptability, user experiences, implementation barriers, and facilitators to support future implementation in routine clinical practice.
