Diabetic foot ulcers (DFUs) are among the most serious and costly complications of diabetes, affecting an estimated 15–25% of all individuals with diabetes during their lifetime. These chronic wounds frequently lead to severe infections, hospital admissions, and lower-extremity amputations, imposing a heavy physical, emotional, and financial burden on patients and healthcare systems worldwide. Traditional care requires frequent in-person visits for wound assessment, debridement, offloading, and infection management—a regimen often impractical for those with limited mobility, transportation challenges, or rural residence. Telehealth solutions have emerged as a transformative approach to deliver continuous, expert-guided care remotely, enabling earlier detection of deterioration, more frequent monitoring, and enhanced patient engagement. By integrating digital tools such as high‑resolution wound cameras, mobile applications, and real‑time videoconferencing, clinicians can now oversee wound healing from a distance, reducing the risk of complications while improving patient convenience and quality of life. This article examines the current state of telehealth for DFU management, the technologies powering it, the evidence supporting its effectiveness, and the persistent challenges that must be addressed for full integration into standard practice.

The Burden of Diabetic Foot Ulcers

DFUs develop from a combination of peripheral neuropathy, peripheral arterial disease, and repetitive mechanical stress on the feet. Neuropathy leads to loss of protective sensation, allowing unnoticed trauma and prolonged pressure. Poor circulation impairs wound healing and increases infection risk. Globally, the prevalence of DFUs among diabetic individuals is estimated at 6.3%, with annual incidence rates around 1–4%. The consequences are severe: DFUs precede more than 80% of non‑traumatic lower‑limb amputations, and the five‑year mortality rate after amputation exceeds that of many common cancers, including breast and prostate cancer. The economic toll is equally staggering—the U.S. healthcare system alone spends an estimated $9–13 billion annually on DFU‑related care, while the indirect costs from lost productivity and disability add billions more. Effective management and prevention are therefore critical, and telehealth offers a scalable solution to improve outcomes while reducing the logistical and financial burdens of frequent clinic visits. The burden also falls disproportionately on underserved populations, including rural communities, ethnic minorities, and those with lower socioeconomic status, who often face delayed diagnosis and limited access to specialist care.

Traditional Management Approaches

Conventional DFU management relies on a multidisciplinary team approach that includes podiatrists, wound care nurses, endocrinologists, and vascular surgeons. Core elements of care include:

  • Offloading: Using casts, boots, or removable walkers to redistribute pressure away from the ulcer.
  • Debridement: Removal of necrotic tissue and callus to stimulate granulation.
  • Infection control: Appropriate antibiotics and topical antimicrobials.
  • Vascular assessment: Evaluation of perfusion and revascularisation when indicated.
  • Glycaemic control: Optimising blood glucose levels to support healing.
  • Patient education: Daily foot inspection, proper hygiene, and shoe modifications.

Despite established protocols, access to specialist care remains inequitable. Many patients cannot attend weekly or biweekly appointments due to distance, disability, or cost. This gap has accelerated interest in remote monitoring and virtual care models, which can bring expert oversight directly into the home. Moreover, standard care often lacks the intensity required for complex or slow-healing wounds, leading to prolonged healing times and higher complication rates.

Telehealth Emerges as a Solution

Telehealth for DFU management encompasses a spectrum of technologies and service delivery models designed to replicate key aspects of in‑person care at a distance. The primary modalities include synchronous videoconferencing (live consultations), asynchronous store‑and‑forward systems (captured images reviewed later), and remote monitoring with wearable or nearable sensors. An integrated telehealth programme may combine all three, providing a comprehensive platform for wound surveillance, clinical decision support, and patient self‑management. The COVID‑19 pandemic acted as a catalyst, rapidly accelerating adoption and regulatory acceptance of virtual wound care.

Remote Monitoring Technologies

Advancements in digital imaging and sensor technology have made remote wound assessment increasingly reliable. High‑resolution cameras, often integrated into smartphones or dedicated handheld wound cameras, allow patients or home care nurses to capture standardised images of the ulcer. These images are uploaded to a secure portal for clinician review. In addition, emerging wearable devices such as smart socks or insoles can measure temperature, pressure, and moisture, flagging early signs of inflammation or abnormal loading that precede ulcer formation or recurrence. Mobile health applications guide patients through daily foot checks, track outcomes, and provide automated reminders for dressing changes and medication adherence. Some platforms now use computer vision algorithms to automatically measure wound dimensions and track changes over time, reducing inter‑observer variability and enabling objective trend analysis.

Virtual Consultations and Store‑and‑Forward Systems

During a live video visit, the clinician can visually inspect the wound, assess surrounding skin condition, and evaluate mobility and offloading devices. The patient or a caregiver holds the camera at the recommended distance and angle. If the clinician suspects infection or ischaemia, they can expedite referral for further investigation. Store‑and‑forward systems are particularly useful in low‑bandwidth settings—the patient transmits high‑resolution images, and the clinician responds within a defined timeframe (e.g., 24–48 hours). This model has demonstrated high concordance with face‑to‑face assessment for wound characteristics such as size, depth, exudate level, and necrosis. A 2021 study in the Journal of Wound Care reported >85% agreement between remote image assessment and in‑person evaluation for key ulcer parameters. More recent work has shown that remote assessment can accurately identify the need for debridement or additional imaging, further supporting its clinical utility.

Patient Education and Self‑Management Platforms

Telehealth is not limited to clinical surveillance; it also serves as a powerful educational tool. Structured online programs teach patients how to perform appropriate wound care, recognise warning signs (e.g., erythema, odour, increased pain), and adhere to offloading regimens. Video modules, interactive quizzes, and direct messaging with a nurse educator reinforce learning. Improved self‑efficacy translates into better outcomes, as patients become active partners in their healing journey. For example, the National Health Service (NHS) in the U.K. has rolled out a digital foot care programme that combines remote monitoring with tailored education, resulting in higher patient activation scores and reduced ulcer recurrence rates. Similarly, a programme at the University of Texas Southwestern Medical Center reported that patients using a smartphone‑based education app had a 40% lower rate of readmission for wound complications over six months.

Evidence for Telehealth in DFU Management

Multiple systematic reviews and randomised controlled trials support the effectiveness of telehealth for DFU healing and complication reduction. A 2022 meta‑analysis published in the Journal of Wound Care found that telehealth interventions significantly increased the proportion of healed ulcers (relative risk 1.33) and reduced amputation rates by 40% compared with usual care alone. Another study from the Journal of Diabetes Science and Technology demonstrated that patients using a smartphone‑based wound monitoring system had 50% fewer emergency department visits and 30% fewer hospitalisations over six months. A pilot programme run by the U.S. Department of Veterans Affairs showed that remote wound care monitoring cut average healing time by nearly three weeks and saved an average of $1,200 per patient in travel and clinic costs. A 2023 systematic review in Diabetes Care added that telehealth interventions were associated with improved cost‑effectiveness, particularly for patients living more than 50 miles from a wound care centre.

Nevertheless, evidence quality varies; many studies are small, short‑term, or lack blinding. The heterogeneity of telehealth interventions also makes direct comparisons challenging. However, the trajectory points toward telehealth as an evidence‑supported adjunct—and in some contexts, a replacement—for standard in‑person follow‑up. Ongoing large‑scale trials, such as the TELE‑DFU trial sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases, will provide further clarity on optimal implementation strategies and long‑term outcomes. Real‑world data from large health systems, such as Kaiser Permanente, are also beginning to emerge, showing sustained improvements in healing rates and patient satisfaction when telehealth is integrated into routine care.

Overcoming Barriers to Adoption

Despite promising results, widespread adoption faces several hurdles. Technological and digital literacy barriers disproportionately affect older adults, minority populations, and those with lower socioeconomic status—the same groups at highest risk for DFU. Solutions include providing low‑cost devices, training home health aides, and designing interfaces with large text and simplified navigation. Data security and privacy remain paramount; platforms must comply with HIPAA (U.S.) or GDPR (Europe) regulations and use end‑to‑end encryption. Reimbursement policies have been a critical enabler—during the COVID‑19 pandemic, many insurers expanded telehealth coverage, but some restrictions have since returned. Advocacy is needed to make remote wound care a permanently covered service. Clinician acceptance also requires robust evidence of reliability, clear workflows, and integration with existing electronic health records (EHRs) to avoid extra documentation burden. The Diabetes UK website offers resources on foot care that can help clinicians and patients understand the rationale behind telehealth adoption.

Workflow Integration and Regulatory Considerations

For a telehealth programme to succeed, it must fit seamlessly into existing clinical workflows. This means defining roles for triage nurses, wound specialists, and technical support; establishing clear escalation protocols for abnormal findings; and ensuring that remote assessments are documented in a way that meets medicolegal standards. Regulatory harmonisation across regions is also important—the CDC’s Diabetes Statistics Report provides national data that can help policymakers allocate resources for telehealth infrastructure. Additionally, health systems must consider licensure requirements for providers offering telehealth across state lines, as well as parity laws that ensure equal reimbursement for virtual and in‑person services.

Future Directions: AI‑Powered Wound Analytics

The next frontier in telehealth DFU management is the application of artificial intelligence (AI) and machine learning to wound images and patient data. Algorithms can now automatically measure wound dimensions, detect changes in tissue composition (granulation vs. slough vs. necrotic tissue), and predict healing trajectories with high accuracy. When integrated into a telehealth platform, AI can provide real‑time decision support, flagging wounds that are at high risk of delayed healing or infection for immediate clinician review. Early studies indicate that AI‑assisted assessment achieves accuracy comparable to expert clinicians while reducing evaluation time by up to 60%. Combined with longitudinal data from wearables, such tools could enable truly personalised and proactive management—adjusting offloading recommendations or initiating biologics weeks before a wound deteriorates. The Wound Healing Society recently published a consensus statement urging standardised datasets to accelerate AI development in wound care. Moreover, natural language processing (NLP) of clinical notes and patient‑reported outcomes can further enrich predictive models, identifying subtle patterns that human clinicians might miss.

Implementing a Successful Telehealth Programme

Healthcare organisations considering a telehealth programme for DFU should address several operational aspects:

  • Technology selection: Choose validated wound cameras, apps, and secure platforms that integrate with the EHR. Evaluate solutions that offer AI assistance for measurement and triage. Consider scalability and vendor support for ongoing updates.
  • Workflow design: Define roles for triage nurses, wound specialists, and technical support. Establish clear protocols for escalation of abnormal findings. Map out how telehealth visits will complement or replace in‑person visits, including frequency of remote monitoring versus clinic appointments.
  • Patient onboarding and training: Provide hands‑on instruction, printed guides, and a help desk to overcome initial barriers. Consider home visits from a community health worker for the first session. Use teach‑back methods to confirm understanding.
  • Outcome measurement: Track healing rates, amputation incidence, emergency department visits, patient satisfaction, and cost savings to demonstrate value. Use validated tools such as the Pressure Ulcer Scale for Healing (PUSH) or the Bates‑Jensen Wound Assessment Tool. Include patient‑reported outcomes like quality of life and pain scores.
  • Continuous quality improvement: Regularly solicit feedback from patients and clinicians to refine the programme. Analyse data on no‑show rates, image quality, and time to response. Share results at local wound care conferences to build buy‑in and secure ongoing funding.

Partnerships with technology vendors and academic medical centres can accelerate implementation. For further guidance, the Wound Healing Society provides clinical practice guidelines that can be adapted for telehealth delivery. Additionally, leveraging existing quality improvement frameworks, such as Plan‑Do‑Study‑Act cycles, can help organisations iteratively optimise their telehealth services.

Conclusion

Remote management of diabetic foot ulcers through telehealth solutions represents a paradigm shift in wound care. By enabling frequent, low‑barrier access to specialist assessment, empowering patients through education and self‑monitoring, and leveraging advanced technologies such as AI, telehealth has the potential to significantly reduce the rates of infection, hospitalisation, and amputation. While challenges around equity, reimbursement, and workflow integration remain, the evidence base continues to strengthen, and the momentum generated during the pandemic has permanently reshaped expectations for virtual care. For clinicians and healthcare systems committed to improving outcomes for people with diabetes, investing in robust telehealth programmes is no longer optional—it is essential for modern, patient‑centred care. The next decade will likely see tighter integration of remote monitoring, AI analytics, and multidisciplinary virtual teams, ensuring that every patient with a diabetic foot ulcer receives timely, expert care regardless of geography or socioeconomic status.
