About

Study Aims Specifically with our Healthy Weight Management patients that are pursuing sleeve gastrectomy surgery, the investigators would like to determine if the Fitbit is associated with health outcomes in this population.

Primary Outcome

• Percentage of excess weight loss - Does the use of a Fitbit positively affect the percentage of excess body weight loss in vertical sleeve gastrectomy patients?

Secondary Outcomes

  • Lifestyle changes and Exercise patterns - Does the use of a Fitbit foster positive lifestyle and exercise pattern changes in post-operative VSG patients?
  • Resolution of comorbidity - Does the use of a Fitbit positively affect patient health via reduction of co-morbid conditions associated with morbid obesity following VSG surgery?

Research Methodology This study will be focused on a bariatric post-surgical population and is designed as a randomized controlled trial (RCT) with three arms; a RCT with a control and intervention group and a historical control group. For the RCT, subjects, after providing informed consent, will be randomized into either the control arm or the intervention arm. In the control arm, subjects will be provided normal/standard of care for post-surgical bariatric patients. This includes physician visits, dietary and exercise consults, education and other therapy as appropriate for their care. In the intervention arm, subjects will be provided with a Fitbit bracelet and software to monitor their physical activity in addition to the normal/standard of care provided in the control group. Both groups will receive the recommended aerobic and strength training exercise guidelines. Furthermore, each group will have identical exercise education regarding appropriate intensity using either rate of perceived exertion or target heart rate range. At the end of the 12-month tracking period of the study, the control group will be provided with a Fitbit bracelet so that they can begin tracking their activity levels during the 2nd post-operative year. A third group, the historical controls, at the end of the study will be extracted from the electronic medical records from patients who have meet the same inclusion/exclusion criteria and were surgical patients with completed follow-up prior to the start of the RCT portion of the trial.

RCT subjects randomized to the intervention group will be provided with step by step instructions on how to set-up the Fitbit app on their smartphone and or view the data on the Fitbit secure portal. Additionally, subjects will be shown how to track their weekly structured aerobic and strength training exercise within the app. Users will also be shown how to access Fitbit data on the MyLGHealth portal. Data from the Fitbit will also be accessible to the provider on EPIC flow sheets. Providers will be able to incorporate this data into discussions with patient at visits. RCT subjects randomized to the control group will receive the same training and a Fitbit device after they complete their 12 month visit.

Just prior to the start of the RCT, we will be conducting a pilot study to test the implementation of the Fitbit in this patient population. The pilot phase will initially target 5 patients to enroll as a test of the set-up of the Fitbit monitoring, data transfer, activity logs and other data collection procedures. Subjects in this pilot phase will only participate for a period of 1 month and all individuals will receive a Fitbit device. The investigators will employ all inclusion/exclusion criteria, recruitment procedures and complete all data collection procedures (baseline and follow-up) as planned for the randomized trial. If additional adjustments need to be made relative to the Fitbit set-up or training/reference materials for patients, another 5 pilot patients may be recruited. Data collection and study procedures on all pilot subjects will be completed before the randomized trial begins. This pilot study will be submitted to the IRB for review and approval as a separate study prior to the RCT portion of the study.

For the RCT portion of the study, subjects will be recruited, enrolled and randomized into the study and then baseline data will be collected and entered into the study database. These data elements include subject demographics (age, gender, weight entering program, preoperative weight, comorbidities, lifestyle and physical activity patterns, etc.). Subjects will be followed for one year or until lost to follow-up with data collected at each physician office visit. At each office visit, the investigators will extract from Epic the date of the visit, subject weight and comorbidities. Lifestyle and physical activity patterns will only be assessed at the 2 week, 1 month, 4 month, 8 month and 12 month visits. The historical control group will be extracted at the end of the study when RCT subjects are nearing the completion of their 12 month follow-up.

The historical controls will consist of a group of patients that will have already received surgery and completed 12 month follow-up prior to the start of the pilot and RCT portions of the project. There will be no interaction with them as a part of the study. The investigators are planning to identify them and collect data at the end of the RCT portion of the project.

213 participants in 3 patient groups

Intervention
Experimental group
Description:
At the 2 week post-surgical visit, subjects will receive and be trained in the use of the Fitbit and data interface and meet with the exercise physiologist or research coordinator to initiate MyLGHealth, lifestyle/activity data collection. Subsequent data collection time-points correspond with follow-up post-surgical appointments either at each visit or the 2 week, 1 month, 4 month, 8 month or 12 month visit.
Treatment:
Behavioral: Fitbit
Control
No Intervention group
Description:
At the 2 week post-surgical visit, all subjects will then meet with the exercise physiologist or research coordinator to initiate MyLGHealth, lifestyle/activity data collection. Subsequent data collection time-points correspond with follow-up post-surgical appointments either at each visit or the 2 week, 1 month, 4 month, 8 month or 12 month visit. The control group will receive a current version of the Fitbit device at the end of their completion of the 12 month visit.
Historical Control
No Intervention group
Description:
The investigators will extract historical control data from the electronic health record using electronic queries and manual data extraction. Historical controls will have surgery and 12-month follow-up completed prior to the start of the RCT.
