Benefits of telemedicine: How remote access to care can help you

• The benefits of telemedicine include reducing geographic barriers, improving access to care, cutting down on travel time, and preventing the spread of illness.
• You can benefit from using telemedicine in many medical fields — such as psychiatry, urgent care, dermatology, dentistry, and physical or occupational therapy.

Telemedicine, or telehealth, is medical care that you can receive digitally without seeing a doctor in person.

Telehealth services can take place through live video conferencing, remote patient monitoring, and email, text, or voicemail exchanges between you and your doctor.

About 76% of hospitals in the US offer telehealth services. To determine which services you'll be able to access in your area, contact your health care provider or medical institution.

The benefits of telemedicine

Here's what you need to know about the advantages of telemedicine and which kind of medical services are suited well for remote access.

Telemedicine prevents the spread of illness

Telemedicine isn't new, but demand for telehealth services has increased because of COVID-19. For example, one telemedicine service, Teladoc Health, reported a 50% increase in demand in March, and has added thousands of doctors to its network in response.

More people are opting to use telehealth services now because it limits potential exposure to infection. This can be especially useful for those who are considered high risk, like the elderly population or people with pre-existing medical conditions, says David Cutler, MD, family medicine physician at Providence Saint John's Health Center.

Telemedicine improves access to medical care

Before the COVID-19 outbreak, telemedicine was most commonly used by those with limited mobility, such as people with a spinal cord injury or neuromuscular disorders.

Additionally, telemedicine has been advantageous for people in rural areas with limited access to care — in fact, about 8.6 million Americans do not have a hospital within a 30 minute drive from where they live.

Telemedicine is flexible and convenient

Even if you live near a doctor, telemedicine can be more convenient than traditional office visits. It eliminates travel time, cuts down on waiting rooms, and allows for more flexible scheduling outside of regular office hours.

"You don't need to drive to the office, don't need to find or pay for parking, and don't need to wait in a waiting room," says Adam Solomon, MD, Chief Medical Officer at MemorialCare Medical Foundation. "These types of visits can be especially useful for minor illnesses that don't need much of a physical exam."

Telemedicine allows for easy management of chronic illness

With remote patient monitoring, some chronic conditions like diabetes or high blood pressure can be more easily managed, says Jackielyn Harris, an ER nurse and hospital supervisor at Kaiser Permanente.

For example, some patients can use at-home devices — like blood pressure cuffs, digital scales, and blood glucose monitors — to record vital data that can be digitally transferred to your doctor.

However, telehealth can't completely replace in-person visits for chronic conditions. Someone with diabetes will still need an annual in-person eye exam, as well as a physical exam to check for diabetic neuropathy, which is nerve damage caused by high blood sugar levels.

How can telehealth benefit me?

Exactly how you can work with your doctor remotely depends on what kind of medical care you are seeking.

Here's a look at how you can benefit from using telemedicine in each of these different fields.

Psychiatry

Many mental health conditions can be managed remotely without the need for in-person visits. For example, your healthcare provider can discuss symptoms, offer counseling, adjust your medication, and order prescriptions all through telehealth services.

"There is also a shortage of behavioral health providers and telehealth removes the barrier of distance from treatment, increasing the number of available providers, especially for remote locations," says Solomon.

Solomon says that a real-time video interaction between the provider and the patient is best for treating mental health conditions like anxiety and depression. Some resources on how to access this care include Online-Therapy.com, iCounseling, and more.

Urgent care

Urgent care provides immediate treatment for both acute and chronic illnesses, and is meant to be an alternative if your primary care physician is unavailable.

"These types of visits can be especially useful for minor illnesses that don't need much of a physical exam, like a rash or eye infection," says Solomon.

Many common ailments can be diagnosed effectively over a video conference, or with photos sent through a secure platform.

• Sinus infection symptoms, such as nasal congestion, pressure behind the eyes, or headaches
• Throat and ear aches
• Conjunctivitis (pink eye)
• Skin conditions like rashes and bug bites

Dermatology

Many skin conditions are relatively straightforward to diagnose and treat via video conferencing, says Maggie Kober, MD, a dermatologist with Apostrophe. That's because many skin conditions can be evaluated visually and treatment doesn't require meeting with a dermatologist in person.

Some common conditions that are easily managed via teledermatology include:

• Acne
• Rosacea
• Male androgenetic alopecia (male baldness)

Severe burns, more complex rashes, and skin cancers will often require in-office visits and further procedures, Kober says.

Physical therapy and occupational therapy

Videos or photos demonstrating stretches and exercises can be a good supplementation to in-person exams, but telemedicine can not completely replace physical and occupational therapy, says Alejandro Badia, MD, FACS, an orthopedic surgeon in Florida.

Badia uses a mobile app with many of his patients where he can answer questions and share videos of himself describing and demonstrating exercises. Live video conferencing can also be a good way to receive physical or occupational therapy, as your provider can supervise your movements and make sure they are done properly.

"There's no question that hands-on rehab is more critical," Badia says. "But we are going to continue to see more [telemedicine] to some degree."

Dentistry

Dentists are able to use live video and oral cameras to examine patients' mouths, discuss exams and develop a care plan, says Sean Boynes, DMD, vice president, of health improvement at DentaQuest Partnership for Oral Health Advancement.

With the use of portable x-ray units, some dental hygienists can even take x-ray images to upload and send them to the dentist. This procedure does require the hygienist to visit your home, but limits your exposure to others in the dentist's office.

If your dentist suspects a tooth decay or cavity from your exam or photos, you will have to go to the office to get treated, but teledentistry allows you to consult with your dentist and determine if you need to be seen in person.
