A new outcomes study of real-world data shows that patients at risk of neuropathic foot ulcers had 68% less ulcers and 83% less amputations while on Siren’s continuous remote temperature monitoring program.

The study looked at the healthcare outcomes of 115 high-risk patients from 15 geographically diverse podiatry offices that were provided Siren Socks by their provider. The real-world results show that the Siren’s continuous remote temperature monitoring program is an effective strategy to prevent foot ulcer development and nontraumatic foot amputation among high-risk patients, and to reduce overall cost to the healthcare system.

Diabetic foot ulcers are the leading cause of nontraumatic foot amputations

Neuropathic foot ulcers are the leading cause of nontraumatic foot amputations, particularly among patients with diabetes. Diabetic foot ulcers and amputations are preventable by monitoring temperature to catch early signs of injury and inflammation. Since 2007, a series of large-scale randomized control trials have shown the efficacy of temperature monitoring. This latest study extends the existing literature as the first study to show the effectiveness in a real-world setting.

Continuous remote temperature monitoring socks

At the heart of the study are Siren Socks. Siren Socks monitor temperature and activity data continuously throughout the day. By monitoring the data continuously the Socks are able to minimize false positives and reduce physician workload. The continuous temperature monitoring prevention program also consists of a team of remote nurses who monitor the temperature data and contact a patient when a temperature difference between the feet is found. The nurses ask the patient to reduce activity, check their feet, report symptoms, send photos, and continue wearing the socks. If the problem persists, the nurse escalates it to the patient’s managing physician—in this particular study, the podiatrist—who then decides the next steps and whether the patient needs to be seen in person at the clinic for further diagnosis and treatment as part of standard diabetic foot care.

Real-world data

The study conducted a retrospective analysis using real-world patient data from private podiatry offices. By comparing the outcomes of patients using Siren’s temperature-monitoring socks, the study assessed the effectiveness in a real-world setting. The study was conducted with real-world patient data from patients who were enrolled by their provider in a remote temperature monitoring program. Earlier studies done with Siren Socks showed patients wore the socks more than 5 days a week and 12 hours a day on overage.

A significant decrease in ulcers and amputations

The study observed a 68% decrease in the incidence of foot ulcers among users of the program. 83% fewer amputations were observed, as well as a 32% decrease in outpatient podiatry visits. 

The study represents a significant advancement in diabetic foot care. Continuous remote temperature monitoring can play a crucial role in early detection and prevention of serious foot complications.
