Trial Outcomes & Findings for Multi-Component Prehabilitation for Major Elective Surgery (NCT NCT05752474)
NCT ID: NCT05752474
Last Updated: 2025-12-03
Results Overview
Measurement: Percentage of patients to whom we can deliver an adequate dose (≥50% of the planned sessions) of the 3 core interventions: physical therapy (≥4/8 sessions), nutrition (≥2/3-4 sessions), and meditation (≥2/3-4 sessions). Range: 0-100% (higher values indicate higher feasibility).

Prehabilitation: An Individualized, Multi-component Program
This single-arm trial was conducted at Beth Israel Deaconess Medical Center (enrollment site) and Hebrew Rehabilitation Center (intervention site) in Boston, Massachusetts, from March 2023 to January 2025. Patients 65 years or older scheduled for major abdominal, gynecological oncologic, urologic, and cardiovascular procedures were eligible. The program included the following components:
1. Physical therapy: Participants received two one-hour individual sessions per week, delivered by a physical therapist at the Hebrew Rehabilitation Center.
2. Nutrition: Participants received a one-hour individual nutritional counseling virtually by a registered dietitian. They were supplied with a protein bar or drink containing 20 grams of protein and instructed to consume daily, preferably within 30 minutes of exercise, to maximize muscle protein synthesis.
3. Meditation: A meditation instructor at the Beth Israel Deaconess Medical Center Sadhguru Center for a Conscious Planet led a weekly one-hour virtual group meditation session. These sessions focused on breathing techniques and mindfulness practices to alleviate psychological stress, manage anxiety, and promote mental well-being.
