Brief Summary:
The purpose of this study is to test if a patient can be directly connected to a quality assurance (QA) database, traditionally known as a registry. Patient-reported outcomes (PRO) data will be entered into the database directly from a patient's mobile phone from their index procedure for 12 months. The investigators hope this study to be a "proof of concept" for such a distributed registry and evaluate 1) consistency of data acquisition, 2) engagement of patients, 3) overall value of patient-reported outcomes to enhance long term follow up.

Study Type : Observational [Patient Registry]
Estimated Enrollment : 100 participants
Observational Model: Case-Only
Time Perspective: Cross-Sectional
Target Follow-Up Duration: 12 Months
Official Title: Distributed Registry Study
Actual Study Start Date : April 1, 2019
Estimated Primary Completion Date : September 30, 2019
Estimated Study Completion Date : December 31, 2019

Group/Cohort Intervention/treatment
Patients undergoing vascular surgery procedures
Patients will report outcomes via their smartphone.
Behavioral: Patient reported outcomes

Patients will download the research app onto their phone and enter pertinent medical history and surgical history data similar to standard registries for specific procedures. Over the next 12 months the investigators will obtain patient-reported outcomes (PROs) using the patient's phone.

Specifically, the investigators will obtain daily activity data, weekly 6-minute-walk tests, and quarterly quality of life surveys

Primary Outcome Measures :
  1. Patient Reported Outcomes (PROs) using mobile app [ Time Frame: 1 Year ]
    PROs are any report of the status of a patient's health condition that comes directly from the patient, without interpretation of the patient's response by a clinician or anyone else
