Online form or video visit? Async vs. sync consults

Why the right consultation depends on your state, your situation, and the therapy

Educational information only — not medical advice. Talk to a licensed healthcare provider about your situation.

Telehealth does not always mean a video call. Some care involves a live conversation; other care involves a provider reviewing information you submit and responding later.

These approaches are called synchronous and asynchronous care. Both are forms of telehealth, but they are not interchangeable for every patient or service.[13]

The appropriate route depends on applicable rules, the clinical situation, and the care being considered — not simply which option seems faster.

What is asynchronous care?

Asynchronous, or "async," means the patient and provider exchange information at different times.

Examples include submitting a health history, uploading laboratory results, sending images, or exchanging secure messages. A provider reviews the information rather than meeting with you at the same moment. HHS also calls this "store-and-forward" care.[14]

An online intake form may be part of that process. However, completing a form is not the same as receiving a clinical decision.

A provider may need clarification, additional records, a different consultation format, or further evaluation before deciding what is appropriate.

What is synchronous care?

Synchronous, or "sync," means a live interaction.

A video appointment is a common example. HHS also describes real-time audio communication as synchronous care, although whether audio-only care is sufficient for a particular service depends on the applicable requirements.[15]

A live visit allows you and the provider to discuss concerns and follow-up questions in the same conversation. That may be useful when the history is complex or the provider needs more information.

Live telehealth still has limits. A video call does not make every examination or treatment possible remotely.

Why does your location matter?

Telehealth rules can vary across states.

Providers need the appropriate authority to practice where the patient is located. Depending on the state and profession, that authority may involve a full license, a compact pathway, registration, or another recognized permission.[16][17]

That is why a service may ask where you will physically be during the consultation — not just where you live.

If you will be traveling, tell the care team before the visit. A provider's authority to treat you may depend on your location at the time care is delivered.[17]

Can every therapy be handled through a questionnaire?

No single consultation format applies to every service.

Async care is a method of exchanging clinical information, not a promise that a questionnaire will be sufficient for a particular treatment. Telehealth practice remains subject to applicable state requirements and the provider's clinical assessment.[14][16]

An intake may therefore lead to a live visit, a request for records, laboratory testing when appropriate, an in-person referral, or a decision not to prescribe.

Neither completing a form nor attending a video appointment guarantees a prescription.

What should you have ready?

For either format, prepare:

• Your current location and contact information.
• A clear description of your concerns.
• Your relevant medical history.
• Your medication, supplement, and allergy information.
• Any requested laboratory reports or other records.
• Questions about follow-up and next steps.

For async care, ask when to expect a response and how to submit additional information. For a live visit, confirm the technology requirements and what to do if the connection fails.

What happens afterward?

Before the consultation ends — or when the provider sends the assessment — you should understand the proposed next step and how to ask questions.

That next step might involve treatment, more information, follow-up, or referral elsewhere. The important feature is an appropriate clinical process, not whether it began with a form or a camera.[14][15]

Telehealth is not an emergency service. For a medical emergency, call 911 or seek immediate emergency care rather than waiting for an online response.
