- Brief Summary
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
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.

Group Intervention Description Personalized prehabilitation Stress Reduction 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 Personalized prehabilitation Nutrition 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 Personalized prehabilitation Physical 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.

- Primary Outcome Measures
Name Time Method Composite immunological score immediately preoperatively Composite immunological score containing a combination of blood immune cell frequencies and intracellular signaling responses. This score will be normalized to "baseline" (i.e. before prehabilitation) score for each patient.
- Secondary Outcome Measures
Name Time Method Five Times Sit to Stand Test immediately preoperatively Changes in physical status will be examined using Five Times Sit to Stand Test. The evaluation should be based on differences between pre- and post prehabilitation performance.
Changes in diet immediately preoperatively Mediterranean Diet Score will be collected. The evaluation should be based on differences between pre- and post prehabilitation performance. A high intake of Mediterranean foods: cereals, legumes, fruit, vegetables, fish, Mon-unsaturated fatty acids to Saturated fatty acids (M/S) ratio, and wine were scored positive (1) and a high intake of the non-Mediterranean foods: dairy and meat negative (0). The score ranged from 0 to 9 and the higher the score the better the compliance to a traditional Mediterranean diet.
Changes in cognitive functions immediately preoperatively Cognitive functions will evaluated by the qMCI test. The evaluation should be based on differences between pre- and post prehabilitation performance.
Incidence of postoperative complications Postoperatively through to 30 days after surgery Postoperative complications will be scored by the Comprehensive Complication Index. The Comprehensive Complication Index (CCI®) is based on the complication grading by Clavien-Dindo Classification and implements every occurred complication after an intervention. The overall morbidity is reflected on a scale from 0 (no complication) to 100 (death).
Cumulative opioid consumption Postoperatively through to day 7 Cumulative opioid consumption will be obtained from the patients' charts up to 7 days after surgery or discharge from hospital if earlier.
Neuropathic pain 30 days after surgery Neuropathic pain will be measured by the Patient Reported Outcome Measurement Information System (PROMIS) Neuropathic Pain Quality scale (PROMIS-PQ-Neuro). The questionnaire contains 5 items questions. Scores are based on patient responses to questions about pain intensity. 0 indicates no pain; 5 indicates the most pain imaginable. The total score may be up to 25.
Changes in quality of life 30 days after surgery Quality of life evaluated thanks to the SF-36 scale is a 36-item patient-reported questionnaire that covers eight health domains: physical functioning (10 items), bodily pain (2 items), role limitations due to physical health problems (4 items), role limitations due to personal or emotional problems (4 items), emotional well-being (5 items), social functioning (2 items), energy/fatigue (4 items), and general health perceptions (5 items). Scores for each domain range from 0 to 100, with a higher score defining a more favorable health state. Results will be normalized on "baseline" (before prehab) scores.
Proportion of compliant patients immediately preoperatively Patient's compliance to prehabilitation programs will be evaluated using a modified Rehabilitation Adherence Measure scale, that will be filled by phone every 7 days during the prehabilitation program, i.e. 2 to 6 times by patient. Compliant patient will be defined by a mean score \>= 8/10.
Timed Up and Go Test immediately preoperatively Changes in physical status will be examined using Timed Up and Go Test. The evaluation should be based on differences between pre- and post prehabilitation performance.
Wall Squat Test immediately preoperatively Changes in physical status will be examined using Wall Squat Test. The evaluation should be based on differences between pre- and post prehabilitation performance.
Body Mass Index immediately preoperatively Body Mass Index will be recorded. The evaluation should be based on differences between pre- and post prehabilitation performance
Amsterdam Preoperative Anxiety and Information Scale immediately preoperatively Prevalence and global severity of anxiety will be evaluated using the APAIS (Amsterdam Preoperative Anxiety and Information Scale). The evaluation should be based on differences between pre- and post prehabilitation performance.
Hospital length of stay 30 days after surgery Hospital length of stay assessed from patients' medical administrative data in days
6 Min Walk Test immediately preoperatively Changes in physical status will be examined using 6 Min Walk Test. The evaluation should be based on differences between pre- and post prehabilitation performance.
Pain Catastrophizing Scale immediately preoperatively Prevalence and global severity of anxiety will be evaluated using the Pain Catastrophizing Scale. The evaluation should be based on differences between pre- and post prehabilitation performance.
Postoperative pain Postoperatively through to 7 days after surgery Pain scores will be assessed daily by the patient-reported Visual Analog Scale. Visual analog scale to assess the perceived stress on a horizontal, non-calibrated line of 10 cm, ranging from very low (0) to very high (10)
