In recent years, mobile health (mHealth) apps have promised improved monitoring of health conditions to improve clinical outcomes. The objective of this study is to conduct a pilot randomized clinical trial (RCT) to evaluate the impact of using remotely collected patient generated health data (PGHD) from older patients undergoing bypass surgery due to chronic limb threatening ischemia. The hypothesis is that integrating PGHD with an EHR system will help providers manage post-surgical symptoms and thus improve post-operative mobility and quality of life health outcomes.

This pilot study aims to evaluate the feasibility of collecting patient generated health data (PGHD) remotely for aiding care management of patients with chronic limb threatening ischemia following vascular bypass or revascularization. DRemote data collected from a publicly available smartwatch will be displayed on an EHR interface for providers to view PGHD. The test of feasibility entails multiple components that include implementing a provider interface for viewing and acting on PGHD, establishing safety, ensuring quality assurance (e.g. quality of remote data collection), successful recruitment and retention of participants, and sufficient remote response rates from patients.

Inclusion Criteria:

• age >= 60; Patients with chronic limb threatening ischemia who are undergoing re-vascular surgery [endovascular or open re-vascularization (bypass)].

Exclusion Criteria:

• High risk of post-surgical amputation based on study physician judgement, non-english speaker, diagnosis of an age-related dementia (e.g. Alzheimer's Disease); unable to communicate because of severe hearing loss; uncorrectable vision impairment that compromises clinical assessments or would cause a safety concern, other significant co-morbid disease that in the opinion of the investigators and study physician would impair the ability to participate in the study or be a safety concern

This is a pilot study that tests feasibility. Collection of data for definitive testing purposes is not appropriate at this stage. If the study tests as feasible we will pursue data sharing under policies set forth by the local institution, privacy office and regulatory authorities. We will also follow any journal requirements for posting deidentified data.

Participants are masked to whether their PGHD are being sent to their care provider. Care providers are masked to who receives standard of care. Investigators (except for one who will be the point person for randomization) will be masked to intervention assignments. Staff assessors will be masked to whether PGHD are being sent to their care provider.
