Asynchronous Care (E-visit) vs Live Video Telemedicine: What Each Option Does & Doesn’t Do

Audience: adult

Telemedicine offers two main ways to connect with healthcare providers: asynchronous care (also called e-visits) and live video telemedicine. Asynchronous care lets you send messages, photos, or health information to your provider at any time. They review your information and respond later. Live video telemedicine allows you to have a real-time conversation with a healthcare provider using video. Each method has benefits and limits. Asynchronous care is convenient for simple questions or follow-ups, but it may not be suitable for urgent or complex issues. Live video telemedicine can handle more detailed discussions and some exams but still cannot replace in-person visits when a physical exam or tests are needed. Understanding what each can and cannot do helps you choose the best option for your health needs.

Red flags — go in person / ER

• Sudden chest pain or pressure — seek emergency care immediately.
• Difficulty breathing or shortness of breath — call emergency services or go to the nearest emergency room.
• Sudden weakness, numbness, difficulty speaking, or severe headache — get urgent medical attention right away.

What telemedicine can do

• Non-urgent medical questions and advice
• Medication refills and follow-up on stable chronic conditions
• Minor skin issues or infections
• Health education and preventive care guidance

What telemedicine cannot do

• Emergency situations or severe symptoms
• Physical exams requiring hands-on assessment
• Diagnostic tests and imaging
• Procedures and treatments needing in-person care

What is Asynchronous Care (E-visit)?

Asynchronous care means you send your health questions, symptoms, or photos to a healthcare provider through a secure platform. The provider reviews your information and replies later, usually within a day or two. This method is flexible and convenient because you don’t need to schedule a live appointment or be online at the same time as your provider.

What is Live Video Telemedicine?

Live video telemedicine lets you have a face-to-face conversation with a healthcare provider using video chat. This allows for more interactive communication, where the provider can ask questions in real time and observe some physical signs, such as skin conditions or breathing. It often feels more personal than asynchronous care.

Choosing the Right Telemedicine Option

Consider your symptoms and needs:

How to prepare for your tele-visit

• Find a quiet, private space with good internet connection for your tele-visit.
• Have your medical history, current medications, and symptom details ready.
• Prepare any questions or concerns you want to discuss.
• Ensure your device (phone, tablet, or computer) is charged and camera/microphone work if using live video.
• Have a list of recent vital signs (temperature, blood pressure) if available.

After your tele-visit

• Follow the provider’s instructions and prescribed treatments carefully.
• Schedule any recommended in-person visits or tests promptly.
• Monitor your symptoms and seek immediate care if red flags develop.
• Keep a record of your telemedicine visit summary and any prescriptions.
• Contact your provider if symptoms worsen or new concerns arise.

FAQs

Can I get a prescription through asynchronous care or live video telemedicine?

Yes, providers may prescribe medications through both asynchronous care and live video telemedicine when appropriate. However, some medications may require an in-person visit depending on local regulations and the medication type.

Is my privacy protected during telemedicine visits?

Telemedicine platforms use secure technology to protect your personal health information. Always use trusted platforms and avoid public Wi-Fi to maintain privacy.

What should I do if my symptoms get worse after a telemedicine visit?

If your symptoms worsen or you develop any red flags, seek emergency care or contact your healthcare provider immediately. Telemedicine is not a substitute for urgent or emergency care.

Can telemedicine replace all in-person doctor visits?

No, telemedicine is a helpful tool but cannot replace all in-person visits. Physical exams, lab tests, and certain treatments require you to see a healthcare provider face-to-face.
