Brief summary

The purpose of this study is to determine whether a program to optimize patient physical fitness and nutrition (prehabilitation) prior to and after plastic surgery involving the abdomen improves surgical outcomes. The investigators hope to determine how a multimodal peri-operative prehabilitation program can be most effective in engaging and motivating patients to physically and mentally get ready for an abdominally-based plastic surgery operation. The overall goal is to determine if this program will improve post-operative recovery after abdominally-based plastic surgery. The importance of this new knowledge is better understanding of ways that plastic surgeons can improve outcomes, engagement, and experience of patients undergoing abdominally-based plastic surgery operations. This would translate to increased healthcare value and better long-term outcomes.

Interventions

Nutrition component: Participants will receive information on how to follow a healthy diet (Mediterranean-style diet) with emphasis on whole foods, plants, lean protein, olive oil; restriction of red meats, processed meats, processed foods, added sugar) Exercise component: Participants will receive an activity tracker to use during the study period (3+ weeks before surgery, and 30 days after surgery). Participants will be assigned strength exercises to work on core strength and proximal muscle strength (biceps/triceps, quads, hamstrings, calves).The exercises will mainly be focused on strengthening the abdominal wall. Exercises will be tailored to patients' individual capabilities. They will also be assigned cardio exercises - either low-intensity steady state cardio vs High Intensity Interval training. Level of cardio exercise will be tailored based on patient's Duke Activity score and baseline activity.

MeasureTime frameDescription
Physical Function Test: Timed-up-and-go test on Post-op Day 90Post-operative day 90Will use the timed-up-and-go test. The timed-up-and go test assesses one's mobility. A lower score signifies better mobility.
Patient-Reported Outcome Measures: Abdominal Surgery Impact Scale (ASIS) on Post-op day 30Post-operative day 30Will use the Abdominal Surgery Impact Scale (ASIS) to assess the patient's perceived health following their surgical procedure. The ASIS score ranges from 18-126, having higher scores indicate better quality of life.
Patient-Reported Outcome Measures: RAND 36-Item Health Survey (RAND-36) on Post-op day 90Post-operative day 90Will use the RAND 36-Item Health Survey (RAND-36) to assess the patient's perceived health following their surgical procedure. The score for RAND-36 ranges from 0-100, having higher scores mean better outcomes.
Patient-Reported Outcome Measures: Abdominal Surgery Impact Scale (ASIS) on Post-op day 90Post-operative day 90Will use the Abdominal Surgery Impact Scale (ASIS) to assess the patient's perceived health following their surgical procedure. The ASIS score ranges from 18-126, having higher scores indicate better quality of life.
Patient-Reported Outcome Measures: RAND 36-Item Health Survey (RAND-36) on Post-op day 180Post-operative day 180Will use the RAND 36-Item Health Survey (RAND-36) to assess the patient's perceived health following their surgical procedure. The score for RAND-36 ranges from 0-100, having higher scores mean better outcomes.
Patient-Reported Outcome Measures: Abdominal Surgery Impact Scale (ASIS) on Post-op day 180Post-operative day 180Will use the Abdominal Surgery Impact Scale (ASIS) to assess the patient's perceived health following their surgical procedure. The ASIS score ranges from 18-126, having higher scores indicate better quality of life.
Patient-Reported Outcome Measures: RAND 36-Item Health Survey (RAND-36) on Post-op day 360Post-operative day 360Will use the RAND 36-Item Health Survey (RAND-36) to assess the patient's perceived health following their surgical procedure. The score for RAND-36 ranges from 0-100, having higher scores mean better outcomes.
Patient-Reported Outcome Measures: Abdominal Surgery Impact Scale (ASIS) on Post-op day 360Post-operative day 360Will use the Abdominal Surgery Impact Scale (ASIS) to assess the patient's perceived health following their surgical procedure. The ASIS score ranges from 18-126, having higher scores indicate better quality of life.
Physical Function Test: 6-minute walk test at Time of EnrollmentTime of enrollmentWill use the 6-minute walk test. The 6-minute walk test will be used to assess aerobic capacity and endurance. A normal walk distance ranges from 400 to 700 m.
