Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Over 30 million surgeries are performed annually in the US. Up to 30% of surgical patients experience delayed surgical recovery, marked by prolonged post-surgical pain, opioid consumption, and functional impairment, which contributes $8 billion annually to US health care costs. Novel interventions that improve the resolution of pain, minimize opioid exposure, and accelerate functional recovery after surgery are urgently needed.

Multi-modal pre-operative optimization programs (or "prehab") integrating exercise, nutrition, and stress reduction have been shown to safely and effectively improve outcomes after surgery. However, no objective biological markers assess prehab effectiveness and are able to tailor prehab programs to individual patients. Surgery is a profound immunological perturbation, during which a complex network of innate and adaptive immune cells is mobilized to organize the recovery process of wound healing, tissue repair, and pain resolution. As such, the in-depth assessment of a patient's immune system before surgery is a promising approach to tailor prehab programs to modifiable biological markers associated with surgical recovery. The primary goal of this clinical trial is to determine the effect of a personalized prehab program on patients immunological status before surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study design is a prospective monocenter single-blinded randomized controlled trial in patients undergoing elective major abdominal surgery.

* Patients will be recruited during the surgical consultation, at least 14 days prior to surgery. If they choose to enroll, they will undergo randomization on the day of enrollment.
* Prehabilitation (Day 0): personalized or standard prehabilitation program will be proposed to the patients for a period of 2 to 6 weeks. Immunological, nutritional, physical, cognitive, anxiety and quality of life status will be quantified at baseline by previously trained personnel.
* From the beginning (Day 0) to the end of the prehabilitation program (Day 14 to Day 42): every 7 days, a compliance questionnaire will be filled by phone, by a trained member of the research team blinded to the treatment arm of the study
* End of the prehabilitation period (Day 14 to Day 42): Immunological, nutritional, physical, cognitive and anxiety status after prehabilitation will be recorded by a trained member of the research team blinded to the treatment arm of the study.
* Surgery (Day S)
* Post operative period

* From Day S (2 hours after surgery end) to discharge from the hospital, length of stay, pain and adverse clinical events will be measured and recorded.
* Immunological status will be assessed at Day S+1 by blood draw.
* Cognitive function, neuropathic pain and quality of life will be assessed at Day S + 30.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Personalized prehabilitation

Patients will participate in a personalized health optimization program combining one-on-one coaching, tailored to each patient's physical, nutritional, well-being and cognitive status baseline. Prehabilitation will last from a minimum of 14 days to a maximum of 42 days before surgery

Group Type EXPERIMENTAL

Physical Prehabilitation

Intervention Type BEHAVIORAL

First, an evaluation of patient's aerobic capacity, functional mobility, functional strength, ambulation, fall risk, and overall mobility will be done by a trained member of the research team. Based on their functional level and preexisting conditions, therapeutic exercises will be recommended to optimize their strength, endurance, flexibility, and functional mobility in preparation for surgery. Decisions about the interventions are based on the assessment, individual patient characteristics, environmental factors, surgical type, and monitoring of the client's response and progress. Weekly sessions are 30-45 minutes long to monitor the client's response and progress their program. Based on their response to exercise (evaluated also by 2 apps: Timed Walk App and Smart Metronome \& Tuner App), re-evaluation via the assessments described above, change their plan of care (alter frequency, resistance, exercises) or discontinuation of treatment could be decided.

Stress Reduction Prehabilitation

Intervention Type BEHAVIORAL

Participants will have the opportunity to learn techniques for mindfulness that have been established to reduce stress and assist with pain management with a member of the research team. Patients will be offered to listen to audio recording of relaxation sessions. Each session contains a relaxation technique that the patient practices while listening to the recording. Then the technique is used the next as a baseline to introduce a new technique more advanced. For some patients who struggle with the techniques the program will be adapted. Patients will choose 2 or 3 techniques and work on them.

Cognitive Prehabilitation

Intervention Type BEHAVIORAL

Cognitive prehabilitation will consist on the daily use of Lumosity training program, an already existing free app built to increase memory skills. The program proposed by Lumosity is tailored to each patient. The use of Lumosity will be monitored at each in-person session. Patients will be expected to complete at least three 5-minute sessions of Lumosity training per day.

Nutrition Prehabilitation

Intervention Type BEHAVIORAL

Nutrition prehabilitation will involve transitioning the patient to the Mediterranean diet with targets regarding hydration and the proportion of fruits, vegetables, whole grains, and healthy fats the patient will consume in a given day. This nutritional program is flexible, and it allows for specific physician and nutritionist-recommended dietary needs to be incorporated. The patient is also given tools to encourage success in healthier eating, including recipes, sample menus, healthy restaurant options, meal kit options, and local CSA box options

Standard prehabilitation

Patients in the control group will be provided with standard instructions in a hard-copy form specific to prehabilitation before surgery associating physical, nutritional, stress-reduction and cognitive recommendations without any personalized coaching for at least 14 days prior to surgery.
