Siren Socks next step in foot care

Siren Announces First Fully Integrated Remote Patient Monitoring Solution in Podiatry

Siren Socks monitoring device combines with nursing support staff

February 27, 2021

Siren, a health technology company that pioneered the development of microsensor-embedded textiles for medical applications, announced that it is augmenting its Siren Socks product offering by launching Siren Staffing, a remote patient monitoring (RPM) program. Initial customers include StrideCare and Village Podiatry Centers.

Siren Socks continuously track foot temperature and were developed to help patients living with diabetes manage their foot health more effectively. Temperature monitoring has been clinically established as an important physiologic marker of injury and is recommended as a tool to detect and prevent diabetic foot ulcers (DFUs). DFUs occur in 25% of people with diabetes, accounting for over $43 billion in annual healthcare costs in the U.S., and are the leading cause of amputations.

Siren Staffing builds on the benefits of Siren Socks by utilizing licensed practical nurses to coordinate RPM activities with podiatric practices. Program nurses monitor temperature data collected by Siren Socks and contact patients who may be at risk of developing injuries to evaluate the status of their feet.

“With Siren Staffing, we now offer the first fully integrated remote patient monitoring solution in podiatry,” said Ran Ma, Siren co-founder and CEO. “We have combined an easy to use monitoring device, continuous data recording and analysis using proprietary algorithms, and a staff of trained nurses into a cohesive, end-to-end offering that allows any podiatric practice to successfully implement RPM and help patients avoid complications arising from foot ulcers."

“Implementing Siren Staffing has made my practice more efficient and effective” said Dr. Gavin Ripp, DPM, of Premier Podiatry & Orthopedics in Northern California. “The team works closely together to monitor patients and coordinate care with our systems. The result is that I am able to quickly act with greater information. This comprehensive solution allows us to monitor more patients to detect signs of inflammation and injury earlier and intervene effectively.”

In Times of COVID-19 Darkness, Remote Patient Monitoring Shines a Light for High Risk Patients

June 11, 2020


People with diabetes are not more likely to get COVID-19 than the general population. The problem people with diabetes face is primarily a problem of worse outcomes, not greater chance of contracting the virus.


Early studies have shown that about 25% of people who went to the hospital with severe COVID-19 infections had diabetes.


One in 10 coronavirus patients with diabetes died within the first seven days of hospitalization, and one in five needed a ventilator to breathe, according to a new study by French researchers.


Diabetes is one of the underlying health conditions that health experts believe put people at greater risk for developing more severe symptoms of Covid-19 and the study, published in the journal Diabetologia, seems to confirm this.


One reason is that high blood sugar weakens the immune system and makes it less able to fight off infections.

It is well known that people with diabetes have increased infection risk, especially for influenza and pneumonia.


Diabetes was previously reported as a major risk factor for mortality in people infected with the 2009 H1N1 pandemic influenza and, more recently, with the Middle East respiratory syndrome-related coronavirus (MERS). Epidemiological studies have quickly and consistently pointed out diabetes as one of the major comorbidities associated with COVID-19 and affecting its severity.


The researchers found that patients who used insulin and other treatments for modifying blood sugar levels did not have a higher risk for developing COVID-19.


It is imperative for diabetics to create a COVID-19 plan as social distancing and shelter in place rules may make it harder to get the supplies and care that you need.


If you start feeling sick, stay home. Check your blood sugar more often than usual. COVID-19 can reduce your appetite and cause you to eat less, which could affect your levels. You also need more fluids than usual when you're sick. Keep water close by, and drink it often.


At Siren, we are dedicated to keeping our high risk patients safe and at home, by allowing them to communicate with their doctor regarding foot health remotely. Our goal is to keep patients safe, connected, and out of the hospital.


Siren Raises $11.8 Million to Power Commercial Expansion of its Smart Fabric Remote Patient Monitoring Solution

May 27, 2020

Siren, a medical device company that has developed breakthrough technology to embed microsensors within fabric, allowing for mass production of affordable, washable smart textiles with remote patient monitoring applications, announced today that it has raised $11.8 million in funding led by Anathem Ventures, with participation from existing investors DCM, Khosla Ventures, 500 Startups, and Peter Thiel’s Founders Fund. In connection with this Series B round of funding, DCM Partner Jason Krikorian will join Siren’s board and Anathem Managing Partner Crystal McKellar will join Siren as an advisor.


Since its founding in 2015, Siren has raised $22 million across three funding rounds to position itself for commercial expansion, including a previously undisclosed $6.5 million Series A in 2018 and a $3.4 million seed round. Siren was the TechCrunch CES 2017 Hardware Battlefield Winner, and was named 2018 CES Best of Innovation for its innovative smart textile technology. 


Empowering Doctors to Effectively Care for Patients Remotely


Siren’s first commercial product is an FDA-registered temperature monitoring sock that connects wirelessly to a software application, allowing podiatrists to detect early signs of inflammation in patients at risk of developing diabetic foot ulcers. The onset of diabetic foot ulcers represents a dangerous condition that, when left unchecked, can lead to serious complications, including amputation. Today, podiatrists largely rely on in-clinic visits to manually monitor the temperature elevations that are the precursor to a diabetic foot ulcer. However, ulcers form in a matter of hours or days and can worsen rapidly between such visits. Siren’s solution enables real-time detection and early intervention, which can prevent the serious complications that result in over 100,000 lower limb amputations every year and cost the US healthcare system over $43 billion annually. 


COVID-19 Changing Healthcare Now and Forever


Siren’s remote monitoring solution is particularly valuable during the COVID-19 pandemic, as it allows healthcare practitioners to stay engaged with and care for their patients remotely, limiting in-clinic visits to true emergencies while delivering additional services for physician practices through CMS’ recent expansion of Medicare reimbursement for remote patient monitoring services. 


“COVID-19 has changed healthcare now and forever. Digitization and virtual care is no longer a nice-to-have, it’s a need-to-have. Patients need remote patient monitoring to collect and send crucial health data to their physicians. Clinics, by transitioning some medical staff into virtual monitoring, can stay operational, prevent job loss, and allow patients continued access to care,” commented Ran Ma, CEO of Siren. “Additionally, as a medical device company, we have changed the way that we do business - how we make sales, provide customer support, and how our products work. The companies who not only survive, but thrive, are the ones best able to evolve and help their customers adapt to this new world.”


Series B lead and Anathem Ventures Managing Partner Crystal McKellar said, “Technology, at its best, should deliver higher functionality at a fraction of the cost. In the healthcare space, this means improving patient outcomes while reducing the financial burden to the system. Siren’s breakthrough technology combines all of these important adoption drivers, and I am thrilled to partner with Siren to help further the company’s growth.” 


DCM Partner Jason Krikorian, a long-time Siren investor who co-led Siren’s 2016 seed round, noted, “When we initially invested, what I saw was a resourceful team and a creative and elegant product that would represent an enormous improvement for patient care and cost-effective physician workflows in any environment.  The current pandemic has made it clear that remote monitoring solutions will be a critical part of any physician’s practice.  I’m excited to work even closer with the team on this next phase of growth.”

Where Telehealth Stops and Remote Patient Monitoring Starts

May 12, 2020

REMOTE PATIENT MONITORING vs Telehealth: Which is right for you?

COVID-19 has brought to light for patients and providers the importance of Remote Patient Monitoring and Telehealth. While they are often lumped in one large “Telemedicine” category and are both valuable in their own ways, these two modalities are in fact different.

What is Remote Patient Monitoring?

Remote Patient Monitoring (often abbreviated as RPM) is a method of healthcare delivery that uses the latest advances in IT to gather patient data outside of traditional healthcare settings. It’s about using technologies to bridge the gap between traditional physical settings of your clinic and people living their every day lives. The most effective RPM systems often consist of consumer-friendly, wearable tech products that seamlessly integrate in to the users life, and a platform for clinics to streamline the data collected and provide a clear picture of the patients health. RPM is giving clinicians the power to know what’s actually occurring with their patients on a daily basis, as it happens, vs relying on their routine scheduled check in, or even a check in via telehealth. Patients are provided with a steady stream of biometric data to the healthcare professionals monitoring their treatment. It automates the process to an extent that makes it easier for both individual and provider to keep on top of the situations in real-time.

What is Telehealth?

Telehealth was originally created as a way to treat patients who were located in remote places, far away from local health facilities or in areas with shortages of medical professionals. While it is still used today to address these problems, it is increasingly becoming a tool for convenient basic medical care.  In short, telehealth is the practice of medicine using electronic and telecommunications technologies (think zoom, facetime, skype, etc.) and services to provide care from a distance. Today’s connected patient wants to waste less time in the waiting room at the doctors, and get immediate care for minor conditions when they need it. Telehealth can be used as a tool, but maybe not a solution for high risk patients. It should be used to screen patients, triage patients, and care for patients who do not need medical intervention.


As we know, COVID-19 can be harmful and even fatal for people with compromised health, and both Remote Patient Monitoring and Telehealth can help these patients avoid exposure. While telehealth can provide routine care for patients with chronic disease who are at high risk, it is limited in proactively alerting the patient or physician of potential ailments as remote patient monitoring can do.


Siren has the best in class Remote Patient Monitoring solution to continuously track foot temperature, keeping patients and providers connected by helping track issues related to inflammation or injury. Temperature monitoring, in contrast to visual checks alone, has been shown to improve outcomes related to ulcers by 87%.*

Remote patient monitoring and podiatry during COVID-19

April 16, 2020

People with neuropathy and those at risk for diabetic foot ulcers are particularly vulnerable during COVID-19. They need high-quality care to avoid complications. But many are scared to see their doctor, and don't know how to keep in touch with their podiatrist from home. In turn, podiatrists are seeing a decline of patients coming in for in-person visits. Remote patient monitoring offers a critical solution to deliver the best care for the patients that need it the most.

Impact of COVID-19 on diabetic foot care

People at risk for foot ulcers are also the most vulnerable when it comes to COVID-19. Many are older, have diabetes, and other co-morbidities that make the Corona-virus particularly dangerous for them. But especially now they need the care to make sure they don't develop foot complications. In order to keep people at home and out of the hospital, it's crucial for their health that they remain connected with their podiatrist.

  1. Less in-person visits and increased risk of complications. Patients are scared to come into the office and are cancelling appointments unless absolutely necessary. The fear is easily justified, but by not going in for regular in-person visits and seeing their doctors as often, they have an increased risk of developing diabetic foot ulcers. Diabetic foot ulcers can be fatal and have extreme consequences. Using remote patient monitoring, patients can be safely monitored from the comfort of their home without having to come into the office.
  2. Risk for healthcare providers. Due to exposure and infection rate, the number of staff available to see patients can decrease. As the virus continues to spread, health care providers will be forced to quarantine themselves. As a result, remaining providers will have to work more with less resources.
  3. Reduced access to care. The cancellations of these appointments are costly to the clinics as revenues are reduced. Medical assistants and nurses may have to be furloughed. Especially smaller and rural clinics are at risk, even though these are crucial for their communities. If clinics start closing, it reduces access to care for our most vulnerable patients. Siren allows clinics to keep their healthcare workers safe, because they can transition into remote patient monitoring instead of being furloughed.

How can Remote Patient Monitoring help your practice during COVID-19?

  1. Maintain relationships with high risk patients. Stay engaged and treat your patients even if they are unable to come in to the office. This will make your patients feel safe, knowing they are still being monitored and cared for by their physician. You can manage and limit in-person visits to only those which are absolutely necessary, while also creating better care for patients at home.
  2. Continue to monitor patients and avoid severe diabetic foot complications. Many patients with neuropathy are at high-risk to develop life-threatening wounds. Without close monitoring and regular check-ins, wounds can go unnoticed. RPM provides the means for monitoring patients who are at greatest risk during their period of self-isolation, protecting clinic staff and patients alike.
  3. Keep your clinic open and retain talented staff. RPM provides a provides a means to supplement some of the lost income from appointment cancellations for routine visits. The reimbursement is carved out specifically for the technology component of remote patient monitoring, so these programs can be more profitable than traditional telehealth services (CPT 99453, 99454, 99457 and 99458). You can keep your office open and retain talented and loyal staff.

Remote temperature monitoring for diabetic foot care during COVID-19

COVID-19 is here and it’s probably going to get worse before it gets better, but we are confident we will get through this difficult time together and that we can still save limbs and lives. With remote temperature monitoring, you can keep patients healthy and at home, and retain your staff to deliver the highest quality of care.

FCC Fights COVID-19 with $200M Telehealth Program

April 14, 2020

Huge news from the Federal Communications Commission earlier this month as they voted in favor of adopting a $200 million telehealth program to support healthcare providers responding to the ongoing coronavirus pandemic. This new program will provide immediate support to HCP’s and patients across the country, including aid for the purchase of telecommunications, broadband connectivity, and devices necessary for providing telehealth.


FCC chairman Ajit Pai issued the following statement on the adoption of the order:

“Our nation’s healthcare providers need us more than ever, and we at the FCC are answering the call. With the adoption of the $200 million COVID-19 Telehealth Program, the FCC can now take immediate steps to provide funding so that more patients can be treated at home, freeing up valuable hospital beds for those who most need them and reducing the risk of exposure to the virus.”

“In addition, the new Connected Care Pilot Program will help us to look to the future and determine how universal service support can shepherd telehealth services into a new era of healthcare delivery. I’d like to thank my colleagues at the FCC for voting expeditiously to adopt these two programs. More than ever, we need to work together to address the needs of the American people in the face of this increasingly challenging time.”


The FCC also adopted final rules to stand up a Connected Care Pilot Program. This separate three-year Pilot Program will provide up to $100 million of support from the Universal Service Fund (USF) to help defray health care providers’ costs of providing connected care services and to help assess how the USF can be used in the long-term to support telehealth.


There is no better time to adopt Siren as your Remote Patient Monitoring platform for best in class foot health. There is power in numbers and here at Siren, we stand by our customers. We are here to help in times of need and will still be here with you once we get through this, together as one.

New Study: Diabetes and Cardiovascular Health in Women

June 14, 2018

The next time you have a doctor, it might be a good idea to get a full physical if you have diabetes. A new study shows that both women and men with diabetes are at an increased risk of developing cardiovascular disease. Results of the study showed that having diabetes tripled the risk of death from ischemic heart disease or stroke in women and doubled the risk for men. This study did not look at individuals with any previous cardiovascular disease, only new events.

Having diabetes may increase your of other conditions like cardiovascular disease. It is important to have regular checkups with your medical doctor to find out your specific risk factors, as well as, the specific precautions you need to take to prevent problems. If you notice any chest pain and/or shortness of breath contact your doctor immediately, call 9-1-1 or go to the nearest hospital if you believe it is a life-threatening condition.

If you have concerns about your risk of having a heart attack or stroke talk to your doctor or CDE. They will be able to tell you if you are at risk, the steps you can take to stay healthy and prevent complications, and how to recognize the signs of a heart attack or stroke.
