Emerging Technologies in Telehealth

The future of telehealth is closely tied to advancements in technology. Several cutting-edge innovations are set to reshape virtual care in the coming years.

Artificial intelligence and machine learning in diagnostics

AI and machine learning (ML) can analyze large amounts of medical data to assist healthcare providers in making more accurate diagnoses and treatment recommendations.

For example, AI-powered diagnostic tools can examine medical images like X-rays or MRIs and flag potential issues for review by human doctors. 

AI chatbots are also being developed to conduct initial patient screenings and triage. These chatbots can ask patients about their symptoms and medical history, then direct them to appropriate care options whether that’s a virtual doctor visit, in-person visit, or emergency services.

Internet of Medical Things for remote patient monitoring

The Internet of Medical Things (IoMT) refers to connected medical devices and applications that can collect and transmit health data. This technology enables continuous remote monitoring of patients’ vital signs and other health metrics.

Some examples of IoMT devices include:

• Smart pills with ingestible sensors to track medication adherence
  
  
• Connected glucose monitors for diabetes management

• AR-assisted remote surgical guidance
  
  
• Immersive mental health treatments like exposure therapy for phobias
  
  
• Medical training and education in virtual environments

For instance, a 2018 study in the Journal of Visualized Experiments found that VR-based physical therapy for stroke patients greatly improved upper limb function compared to conventional therapy (Choi & Paik, 2018).

While technology is important, telehealth’s real strength is in making specialized care available to more people.

Expanding Access to Specialized Care

One of telehealth’s greatest promises is improving access to specialized medical care, especially for underserved populations.

Telepsychiatry bridging the mental health treatment gap

Mental health care has long suffered from accessibility issues, with many areas facing severe shortages of psychiatrists and therapists. Telepsychiatry is helping to bridge this gap.

A 2016 study in the World Journal of Psychiatry found that telepsychiatry was as effective as in-person care for treating depression, with the added benefit of increased patient satisfaction and engagement (Hubley et al., 2016).

Telepsychiatry is particularly valuable for:

• Rural communities with few local mental health providers
  
  
• Patients with mobility issues or transportation barriers
  
  
• People seeking specialized treatments not available locally
  
  
• Those who prefer the privacy and convenience of at-home care

Remote visits with specialists for rural and underserved areas

Telehealth is bringing specialized medical expertise to areas that previously had little or no access. This includes:

• Remote dermatology visits using high-resolution images
  
  
• Virtual neurology assessments for stroke patients

School-based telehealth programs improving pediatric care

School-based telehealth programs are emerging as a powerful tool for improving children’s health, especially in underserved communities. These programs typically involve:

• On-site telehealth equipment in school nurse offices
  
  
• Virtual visits with pediatricians or specialists
  
  
• Management of chronic conditions like asthma or diabetes
  
  
• Mental health services for students

Halterman et al (2017) found that school-based telehealth programs reduced emergency department visits and improved asthma outcomes for children in rural communities.

Virtual second opinions from leading medical experts

Telehealth is making it easier for patients to get second opinions from top specialists, regardless of geographic location. This can be particularly valuable for complex or rare conditions.

Several major medical centers now offer formal virtual second opinion programs. For example, the Mayo Clinic’s eConsults program provides written second opinions from Mayo Clinic specialists based on a review of medical records and test results.

Telehealth is also changing how we approach personalized care and monitoring for patients.

Personalized Medicine and Remote Monitoring

The integration of telehealth with other digital health technologies is enabling more personalized and proactive care.

• Forecast mental health crises based on behavioral patterns

Genomics and telehealth integration for tailored treatments

The combination of telehealth and genomic medicine is opening up new possibilities for personalized treatment plans. Patients can now receive genetic counseling and testing remotely, with results informing tailored treatment recommendations.

For example, pharmacogenomic testing can help determine which medications are likely to be most effective for a particular patient based on their genetic profile. 

Remote medication management and adherence monitoring

Poor medication adherence is a major challenge in healthcare, contributing to worse health outcomes and increased costs. Telehealth-enabled medication management tools can help by:

• Sending reminders to take medications
  
  
• Tracking medication usage through smart pill bottles or ingestible sensors
  
  
• Allowing remote adjustments to medication regimens
  
  
• Providing education about medications and potential side effects

As telehealth grows, we need to update the rules and regulations that guide its use.
