Descriptive Information
Brief Title Distributed Registry
Official Title Distributed Registry Study
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.

Sampling Method Non-Probability Sample
Study Population All adults with an iPhone 5s or higher who can read English
  • Peripheral Arterial Disease
  • Intermittent Claudication
  • Arteriosclerosis
  • Atherosclerosis
  • Arterial Occlusive Diseases
  • Vascular Diseases
  • Cardiovascular Diseases
  • Peripheral Vascular Diseases
  • Signs and Symptoms

Intervention 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

Study Groups/Cohorts Patients undergoing vascular surgery procedures
Patients will report outcomes via their smartphone.
Intervention: Behavioral: Patient reported outcomes
