When a specialist advises a local team during an ultrasound, a remote nurse checks in with a patient, or clinicians join rounds from another facility, the work is telehealth. The technology connects people, information, and care workflows across distance while the responsible clinical team retains accountability.
What is telehealth? Telehealth is the use of electronic information and telecommunications technologies to support long-distance clinical care, health education, health administration, and public health. The term includes telemedicine, but it is broader than a video visit. For healthcare organizations, telehealth can include remote patient interaction, virtual nursing, specialist collaboration, store-and-forward image review, live modality viewing, education, and operational coordination.
This guide explains the term in a healthcare-organization context. It distinguishes telehealth from telemedicine and virtual care, describes the main delivery models, and shows how the concept maps to hospital workflows. It does not replace clinical, legal, privacy, or compliance review. Technology can extend a care team’s reach, but it does not provide medical advice or replace clinical judgment.
What does telehealth mean in healthcare?
The Health Resources and Services Administration defines telehealth as the use of electronic information and telecommunications technologies to support long-distance clinical care, health education, health administration, and public health. That definition is intentionally broad. It describes a category of connected activities, not a single device, software feature, or appointment type.
For a healthcare organization, telehealth is a way to organize work when the patient, clinician, specialist, educator, or operational team is not in the same place. A secure connection may support a consultation. It may also let a remote nurse communicate with a patient, allow a specialist to collaborate with a local imaging team, or connect staff across facilities for education and coordination.
Telehealth is more than a video appointment
Video visits are one recognizable use of telehealth, but they are not the entire category. Telehealth may use interactive audio and video, secure messaging, electronic records, streaming media, store-and-forward systems, and connected clinical devices. The appropriate method depends on the purpose of the interaction, the information participants need, the urgency of the situation, and the organization’s governance requirements.
The broad definition also includes nonclinical activities. A hospital may use telecommunications for professional education, patient education, administrative coordination, or public-health communication. Those activities may not look like a medical encounter, but they still use digital systems to connect people and information across distance.
What telehealth does not mean
Telehealth does not automatically mean care delivered from a patient’s home. Consumer device monitoring can be one form of remote healthcare, but it is not the only model and is not the primary way TeleRay frames remote care. In TeleRay’s hospital-focused model, remote can mean interacting with a patient through telenursing or telesitting. It can also mean viewing a live modality, such as ultrasound, so a specialist can guide a local technician and communicate with the patient in real time.
Telehealth also does not mean that software makes a clinical decision. A platform may transmit information, support communication, or give an authorized professional access to a relevant view. The clinical team remains responsible for assessment, treatment, escalation, documentation, and decisions within its scope of practice.
How is telehealth different from telemedicine and virtual care?
Telehealth, telemedicine, and virtual care are related terms, but they answer different questions. The CDC describes telemedicine as the practice of medicine using electronic communication between a physician in one location and a patient in another, with or without an intervening healthcare provider. Telehealth is the wider category that includes telemedicine and related education, administration, public-health, nursing, observation, and coordination activities.
Virtual care is an operational term. Organizations often use it to describe care interactions and supporting workflows delivered through connected digital tools. The boundaries are not universal, so each organization should define the terms in its policies and governance documents.
| Term | Primary meaning | Healthcare example |
|---|---|---|
| Telehealth | The broad category of digital activities that support care, education, administration, and public health across distance. | Remote nursing, specialist collaboration, virtual education, or store-and-forward imaging. |
| Telemedicine | A clinical subset focused on medical practice between professionals and patients in different locations. | A physician conducts an appropriate consultation through secure audio and video. |
| Virtual care | A practical description of connected care interactions, participants, systems, and workflows. | Telenursing, telesitting, virtual rounds, or a remote specialist supporting a local team. |
Why the distinction matters to healthcare leaders
Terminology shapes planning. A telemedicine program may concentrate on encounter protocols, licensure, documentation, reimbursement, and the responsibilities of the participating clinicians. A broader telehealth strategy must also consider staff education, patient communication, privacy, security, administration, interoperability, and cross-facility coordination.
Virtual care emphasizes how the work is organized. Leaders may need to understand who starts a session, who can access patient information, who responds to an alert, how an encounter is documented, and when responsibility returns to the local team. A clear vocabulary helps clinical, IT, compliance, and operations leaders discuss the same workflow without assuming that one video tool solves every problem.
For a broader look at how TeleRay connects communication and clinical workflows, see the virtual care platform overview. The relevant question is not which label sounds most familiar. It is whether the defined use case has appropriate people, technology, permissions, escalation paths, and clinical ownership.
What are the main telehealth models?
Healthcare organizations commonly describe telehealth by timing and function. The categories overlap, and one workflow may use more than one model. A live consultation may be followed by asynchronous documentation. A remote observation workflow may include real-time communication and an escalation process that connects local staff with a specialist.
Synchronous or live telehealth
Synchronous telehealth happens in real time. Participants communicate through interactive audio, video, or another live connection. Examples include a patient consultation, virtual rounds, remote nursing, telesitting, and specialist guidance during a procedure. The local team can provide physical context and hands-on support while the remote participant contributes expertise or observation from another location.
Live telehealth is useful when participants need to ask questions, clarify information, observe a situation, or coordinate the next action immediately. It still requires defined roles. The remote participant should know what information is available, what decisions are within scope, and how to escalate an issue to the responsible local team.
Asynchronous or store-and-forward telehealth
Asynchronous telehealth does not require everyone to participate at the same time. A team collects relevant information and sends it through an approved system for review later. The information may include a history, report, image, or other clinical record. This model can support specialist review when a live encounter is not necessary or when a deliberate review is more appropriate.
Medical imaging often uses this pattern. A study can move through a DICOM or PACS workflow for later review, while the organization follows its established process for documentation, interpretation, communication, and follow-up. Asynchronous exchange should be secure and governed, but it does not need to be presented as a real-time visit.
Remote observation and monitoring
Remote observation uses connected technology to let an authorized professional observe and communicate with a patient or care environment from another location. In a hospital, telenursing and telesitting may support patient communication, observation, education, or coordination under defined policies. A remote specialist may also view a live modality while a local technician performs an examination.
This hospital workflow differs from defining telehealth primarily as home-based physiological monitoring. The essential question is what the remote participant needs to see, hear, communicate, or review, and what the local team remains responsible for doing. The technology should support a deliberate workflow rather than create uncertainty about ownership.
Education, administration, and public health
Telehealth also supports activities around direct care. Hospitals may connect professionals for training, provide patient education across facilities, coordinate administrative work, or share public-health information. These uses may not create a physician-patient encounter, but they still connect people and information across distance.
Including these activities in the definition matters because healthcare organizations evaluate more than clinical video. They also evaluate how systems affect education, coordination, data access, privacy, and the movement of work between departments and locations.
How does telehealth appear in hospital workflows?
Hospital telehealth is most useful when it fits a real operational need. The connection should make it easier for the appropriate people to participate, access relevant information, and act within established responsibilities. It should not be treated as a substitute for bedside assessment or emergency treatment.
Telenursing and telesitting
Telenursing lets a qualified remote professional communicate with a patient or support designated nursing activities while the local team continues care. Depending on the organization’s policy, the interaction may involve education, intake, discharge support, observation, or coordination. Telesitting applies a related model to remote patient observation. A remote observer can communicate with a patient and alert bedside staff when agreed criteria require local attention.
These workflows depend on more than a camera. The organization needs clear roles, privacy controls, appropriate device placement, reliable communication, and a defined response path. The remote professional complements the local team. The technology does not transfer clinical responsibility away from the professionals designated by the organization.
Virtual rounds and specialist collaboration
Virtual rounds can bring physicians, nurses, specialists, educators, and other approved participants into one conversation when distance or scheduling makes an in-person meeting difficult. A team may use the connection for patient updates, interdisciplinary discussion, education, or consultation. The value comes from relevant information and clear responsibilities, not from adding another generic video call.
Remote specialist support can also connect a central team with a rural, community, or satellite location. The local professionals provide patient context, equipment, and hands-on care. The remote specialist contributes appropriate expertise through the approved workflow. The organization should define how recommendations are communicated, documented, and escalated.
What makes the TeleRay model distinctive?
TeleRay brings virtual care and medical imaging into one healthcare technology platform. Its remote model centers on hospital-based patient interaction, clinical observation, and collaboration around live modalities. With live modality streaming, a specialist can view an ultrasound or another supported modality from a remote location, communicate with the patient, and guide the local technician in real time where clinically appropriate.
This capability is different from a basic video visit and from a workflow that only moves completed images for later review. It connects the people, patient context, and live examination. TeleRay also describes its diagnostic viewing capabilities as FDA 510(k) cleared. That statement does not mean telehealth generally is FDA endorsed, and the technology does not replace qualified clinical judgment.
How can telehealth support medical imaging?
Medical imaging illustrates why telehealth is broader than a video appointment. A specialist may need to review a completed study later, or may need to collaborate while an examination is taking place. These are different workflows with different timing, information, and operational requirements.
Live modality viewing
During a live modality session, a remote specialist can view supported imaging output while the local team performs the examination. The specialist may also communicate with the patient and local technician. This can help the remote participant understand patient position, room context, and the way images are being acquired. The local team remains responsible for carrying out the examination safely and within its training and protocols.
For more detail on this use case, review TeleRay’s page about telehealth for medical imaging modalities. The page should be treated as a service-specific resource. This article uses the example only to explain what telehealth can mean in a hospital context.
Asynchronous image exchange
In an asynchronous workflow, the examination is completed and the resulting images move through an approved DICOM or PACS process for later review. This model remains important for documentation, storage, interpretation, and follow-up. It does not require the specialist to be present during image acquisition.
Live collaboration and later review can work together. An organization may use real-time support when the local team needs guidance, then use its established image-management process for the completed study. The appropriate arrangement depends on clinical policy, credentialing, privacy requirements, interoperability, and the capabilities of the organization’s systems.
What should organizations consider before using telehealth?
The definition of telehealth is broad, so implementation decisions should begin with a specific use case. Leaders can ask the following questions before selecting technology or expanding a program:
- What work needs to happen across distance? Define whether the goal is consultation, observation, education, coordination, live imaging support, or another approved activity.
- Who is involved? Identify the local clinician, remote professional, patient, technician, support team, and accountable owner for each step.
- What information must be available? Specify whether the workflow requires video, audio, patient context, reports, DICOM images, EMR information, or another data source.
- What happens when the workflow changes? Document escalation, connection failure, patient deterioration, specialist unavailability, and transfer of responsibility.
- How will access be controlled? Review identity management, permissions, audit logging, encryption, device security, retention, and incident response with the appropriate privacy and compliance teams.
- How will the work be documented? Define where the encounter, communication, image review, decision, or escalation is recorded and who owns that record.
These questions help an organization distinguish a genuine workflow requirement from a general desire to add video. Teams can then evaluate solutions against the care model. TeleRay’s EMR integration resources and virtual care security and compliance guidance provide additional context for those technical and governance discussions.
Frequently Asked Questions
What is telehealth?
Telehealth is the use of electronic information and telecommunications technologies to support long-distance clinical care, health education, health administration, and public health. It includes telemedicine, but it is broader than a video visit. In a hospital, it can include remote nursing, telesitting, specialist collaboration, virtual rounds, and live or store-and-forward imaging workflows. HRSA’s telehealth definition describes the category’s broad scope.
What is the difference between telehealth and telemedicine?
Telemedicine generally describes the narrower practice of medicine between a physician and patient in different locations using electronic communication. Telehealth includes telemedicine and related activities such as nursing, observation, education, administration, public health, and specialist coordination. Terminology can vary by organization and jurisdiction, so policies should define the terms they use.
Does telehealth mean a video call?
No. A video call can support a telehealth encounter, but telehealth may also use audio, secure messaging, store-and-forward information, remote observation, connected clinical systems, and live modality viewing. The right method depends on the purpose of the workflow, the information participants need, and the organization’s privacy, security, and clinical requirements.
What are examples of telehealth in a hospital?
Examples include telenursing, telesitting, virtual rounds, remote specialist consultation, professional education, cross-facility coordination, asynchronous image review, and live remote viewing of a supported modality such as ultrasound. These workflows extend communication or access to expertise while keeping patient care with the appropriate local and remote professionals.
Can telehealth replace in-person care?
Telehealth can support selected interactions and workflows, but it does not universally replace in-person care. Some situations require physical assessment, hands-on treatment, emergency intervention, or local clinical context. Healthcare organizations should define where remote participation is appropriate and how responsibility is transferred when in-person care is required.
Where does telehealth fit in a broader care strategy?
Telehealth names a broad set of digital activities that connect healthcare work across distance. Telemedicine is a narrower clinical subset, while virtual care describes how connected interactions and supporting systems operate in practice. For hospital leaders, the useful next step is to define the workflow, assign accountability, protect information, and choose technology that supports the work without obscuring clinical judgment.
