Telemedicine: an X-ray of a new model of care

Anyone who watched the 1960s cartoon The Jetsons probably came across the idea of telemedicine long before it actually existed. In one episode, Jane Jetson consults Dr. Kay Racey about a health problem of her son Elroy. All of it over a video call, after calling the doctor by pressing a red button.

Today, although an online consultation is still not quite that easy, the practice has become increasingly common. The model brings many benefits, but it also requires limits and care. This article presents a complete overview of telemedicine and its impact on the healthcare ecosystem.

What is telemedicine and how is it regulated in Brazil

Telemedicine is the delivery of medical services at a distance, using tools that make it possible to assess, advise, monitor and follow patients without the need for an immediate in-person encounter. This modality has the potential to expand access to care, reduce geographic barriers and make initial care easier.

Telemedicine (also officially called telehealth) involves three central pillars:

• Secure communication technology, such as video, apps and the exchange of clinical documents.
• Proper recording of information, including the electronic medical record.
• A preserved physician‑patient relationship, with ethical and technical criteria equivalent to in‑person care.

In Brazil, telemedicine was regulated on an emergency basis by Law No. 13,989/2020, which authorized its broad use during the covid-19 pandemic. This law was replaced by Law No. 14,510/2022, which permanently authorized the practice throughout the country.

The Federal Council of Medicine (CFM) regulated telemedicine through Resolution No. 2,314/2022, which authorizes seven modalities of remote care:

1. Teleconsultation

2. Tele-interconsultation

3. Telediagnosis

4. Telesurgery

5. Telemonitoring or telesurveillance

6. Teletriage

7. Teleconsulting

In private healthcare, Brazil’s National Supplementary Health Agency (ANS) recognizes the practice as part of care, provided it complies with health plan rules on coverage, clinical records, consent and data protection. Regulation has driven the supply of digital services and favored hybrid models of care.

How teleconsultation works in clinical practice

Teleconsultation takes place on secure platforms that allow the physician to assess the patient, give guidance, order tests, prescribe medications and record the entire encounter in the electronic medical record. The process follows the same technical and ethical principles as an in-person consultation, with protocols adapted to the digital environment.

1. Scheduling and pre‑consultation

The patient schedules the appointment in a digital system. The platform collects basic information, clinical history, the reason for the visit and the necessary documents. In some services, this step includes initial triage and preparatory guidance.

2. Secure connection environment

The consultation takes place in an environment with encryption, a ban on recording without consent and mandatory identification of the parties. The physician must ensure privacy, good lighting, adequate audio and the conditions to assess the clinical signs that can be observed by video.

3. Remote clinical assessment

During the encounter, the professional takes a complete history and guides the patient through simple maneuvers when needed, such as measuring temperature or heart rate. If warning signs are identified, the physician refers the patient for in‑person assessment.

4. Treatment decisions, prescriptions and orders

The physician can issue a digital prescription with ICP-Brasil certification (Brazil’s public key infrastructure), order tests, propose treatment and give home care guidance. All decisions must be recorded in the electronic medical record.

5. Documentation and continuity of care

Teleconsultation produces valid documents — medical certificates, reports and referrals. To ensure continuity, the data must be integrated into the patient’s history and shared with the care teams involved.

The impact of telemedicine on the healthcare ecosystem

In Brazil, the adoption of telemedicine grew during and after the pandemic. According to the Brazilian Association of Telemedicine and Digital Health Companies, more than 7.5 million consultations were carried out in the country between 2020 and 2021.

In the public system, recent studies show a significant increase in specialist teleconsultations in SUS, Brazil’s public health system, between 2021 and 2024. Telemedicine has clearly established itself as an alternative for care, especially in regions with fewer specialists.

As for clinical outcomes, there is evidence of a positive impact. A randomized clinical trial conducted by the Federal University of Minas Gerais (UFMG) with 127 heart failure patients showed fewer readmissions and severe outcomes with telemonitoring. After 180 days, the group followed by telemedicine had 26% disease-related readmissions, compared with 46% in the usual care group; all-cause mortality or readmissions were 30%, versus 47% in the control group.

The main benefits of telemedicine can be summarized as:

• Broader access to care, by reducing geographic barriers and speeding up care.

• Better clinical outcomes, with fewer hospital admissions and lower mortality in chronic conditions.

• Greater operational efficiency, with shorter queues, optimized physician schedules and lower administrative costs.

• Stronger continuity of care, with integration between the electronic medical record, telemonitoring and structured follow‑up.

Clinical skills, structural requirements and operating models

Telemedicine requires well-defined clinical skills. The professional must master history-taking adapted to virtual settings, recognize the limits of remote consultation, identify warning signs that justify in-person referral and use protocols that ensure safety, traceability and clear guidance for the patient.

From a structural standpoint, the operation depends on secure platforms, integrated medical records, interoperable systems and devices capable of ensuring good audio and video quality.

Operating models vary by service: tele-guidance, teleconsultation, tele-interconsultation, teletriage and telemonitoring make up different architectures of care. Organizations that want to scale need to map workflows, define indicators and integrate telemedicine into the care cycle, avoiding parallel or redundant services.

The Rivio view

Telemedicine is not just an alternative to the traditional consultation. It has become a mechanism for democratizing access to healthcare, predictability and care coordination. In Rivio’s view, it is essential that remote care connects to the other links in the journey: scheduling, authorization, medical record, SADT (diagnostic and therapeutic support services), billing, auditing and outcome indicators.

Rivio’s AI solution integrates these steps, reduces denials, improves clinical accuracy and strengthens the sustainability of the hospital revenue cycle. As a result, institutions can offer faster, safer and more patient-centered care, with more balanced and efficient operations.
