What is the purpose of this trial?

This trial tests how a mobile health app on a smartwatch can assist doctors in managing recovery after surgery for individuals with chronic limb-threatening ischemia, a condition that reduces blood flow to the limbs. The app collects health data and sends it to doctors to determine if this improves patients' mobility and quality of life post-surgery. Participants will have their data either shared with their doctors (actionable remotely generated health data) or not (non-actionable remotely generated health data) to compare outcomes. The trial seeks individuals with chronic limb-threatening ischemia who are scheduled for bypass surgery and do not have severe dementia or other major health issues that could interfere with the study. As an unphased trial, this study offers participants the chance to contribute to innovative research that could enhance post-surgical care.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the study team or your doctor.

What prior data suggests that this mobile app health data collection is safe for patients with peripheral arterial disease?

Research has shown that using health data from smart devices is generally safe for patients. In studies, walking programs for people with peripheral artery disease (PAD) that incorporate smart devices have demonstrated benefits such as improved walking ability and enhanced overall well-being. No major safety issues have been reported when using these devices to collect health data.

For both types of data—those that require action and those that don't—studies have not identified any major negative effects. Patients track their symptoms with smartwatches, aiding healthcare providers in making informed decisions. This method focuses on gathering information and does not involve new medications or invasive procedures, which typically carry more risks.

Overall, using smart devices to collect health data appears to be well-tolerated by patients without causing harmful effects. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores how remotely generated health data from smartwatches could transform the management of Peripheral Arterial Disease (PAD). Unlike traditional methods that rely heavily on in-person monitoring and decisions based on periodic check-ups, this approach provides real-time data directly to healthcare providers. This could lead to more personalized and timely medical decisions, potentially improving patient outcomes. Additionally, by comparing actionable data visible to doctors with non-actionable data, the study aims to understand the impact of real-time information on treatment strategies.

What evidence suggests that using remotely generated health data is effective for managing post-surgical symptoms in patients with peripheral arterial disease?

Research has shown that mobile health (mHealth) apps can assist people with peripheral arterial disease (PAD). Studies have found that these apps can ease walking and reduce pain during walking. One study discovered that exercise programs using mHealth apps increased both the time people could walk without pain and the farthest distance they could walk. Another study demonstrated that wearable devices, combined with home exercises, improved overall walking ability. In this trial, participants in the ROAMM-EHR arm will have their health data shared with doctors, potentially aiding in symptom management and improving life quality after surgery. Meanwhile, participants in the Active Comparison arm will use the smartwatch app without sharing their data with their medical team. ^{1 2 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Actionable remotely generated health data
• Non-Actionable remotely generated health data

Trial Overview

The ROAMM-EHR Study tests if patient health data collected remotely can help manage symptoms after bypass surgery for critical limb ischemia. Participants will either receive actionable health data alerts integrated with their EHR system or non-actionable information to compare outcomes.

How Is the Trial Designed?

Group I: ROAMM-EHR Experimental Treatment 1 Intervention

Patients will wear a smartwatch equipped with a smartwatch app before their surgery and for approximately a month after the surgery. Patients will be asked to wear the watch every day when awake. When wearing the smartwatch, patients will be asked questions about their symptoms following surgery and data will be sent to providers electronically and displayed in their EHR portal. Healthcare Providers will use this information along with patient medical history to decide on the next course of action. The study does not provide specific instructions about how to care for the patient. Those decisions are made by the provider team and their clinical judgement.

Group II: Active Comparison Active Control 1 Intervention

The active comparison patients will wear and respond to questions on the smartwatch. However, the information will not be viewable by their doctor and medical team. All standard of care procedures will remain.

In a pilot study involving 39 patients with peripheral arterial disease, the TrackPAD app significantly improved the 6-minute walking distance by an average of 83 meters over 3 months, while the control group experienced a decrease in walking distance.

The app also enhanced patients' quality of life related to their condition, particularly in symptom perception and physical functioning, indicating its potential as a supportive tool for managing chronic diseases.

A new automated risk prediction tool for patients with peripheral arterial disease was developed using electronic health records, analyzing data from 1,676 patients over a 5-year follow-up period, which showed a strong ability to predict survival with a c-statistic of 0.76.

The tool stratifies patients into different risk categories, revealing significantly increased mortality risks for higher-risk groups, which can help healthcare providers make more informed decisions at the point of care.

The VascTrac iPhone app, designed to monitor walking distance in patients with peripheral artery disease (PAD), showed that the iPhone's built-in distance algorithm significantly overestimated walking distance by 43%, indicating a need for custom algorithms for accurate monitoring.

While the iPhone accurately counted steps, with a bias of -7.2%, further research is needed to determine if step counting can be a clinically meaningful measure for assessing walking ability in PAD patients.
