Prehabilitation for PAD Revascularization Patients

Study Overview
=================
Brief Summary
-----------------
Patients undergoing elective revascularization of their peripheral artery disease will be randomized to a prehabilitation program or usual care prior to their scheduled procedure.

Detailed Description
-----------------
Patients undergoing elective revascularization for their peripheral artery disease will be randomized to a prehabilitation program prior to their surgery or to usual care. The prehabilitation program is self-directed program designed to improve health and quality of life prior to surgery. The program is currently offered to general surgery patients; this study will examine the feasibility and acceptability of such a program in a different patient population.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Prehabilitation<br>Participants will be referred to the Michigan Surgical & Health Optimization Program in the month leading up to their surgery. Individuals are encouraged to increase their physical activity, practice stress reduction, and other behaviors associated with good health | Behavioral: Prehabilitation<br>* Participants will receive an informational DVD, a pedometer, an incentive spirometer and access to the program website to help promote healthful behaviors and improved well-being in the days leading up to surgery.<br>* Other names: MSHOP - Michigan Surgical & Health Optimization Program;|
| No Intervention: Usual Care<br>Participants will follow the pre-operative instructions provided by their surgical team. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Feasibility of Study as Indicated by Number of Participants | The feasibility of the study will be assessed by analyzing the recruitment of subjects to the study and the compliance of recruited subjects to the protocol. Feasibility will be defined as able to screening, approaching, and enrolling 25 eligible patients to the pilot study. | 1 day | 
| Acceptability of Study as Indicated by Percentage of Participation | The willingness of patients to enroll and complete the basic study procedures. Acceptability will be defined as low drop out-rates (<15%), completion of quality of life surveys, and >85% usage of the pedometers. | 8 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Increased Physical Activity Characteristics | Increased physical activity characteristics will be assessed through the Godin Leisure Time and International Physical Activity Questionnaire, and questionnaires on barriers to and self-efficacy of exercise. | 8 months | 
| Health-related Quality of Life | Health-related quality of life and physical activity characteristics will be measured during the pre, peri, and post-operative period. This will be done through PROMIS surveys, which assess physical function, fatigue, depression, anxiety, and ability to participate in and satisfaction with social roles/activities. | 8 months |
