Preventing digital exclusion through nurse-assisted teleconsultation: equity-stratified analysis of patient-reported outcomes and usability from the TELECONSULTA pragmatic randomized trial
In a Brazilian pragmatic randomized trial involving adults with type 2 diabetes, nurse-assisted teleconsultation demonstrated equitable usability and preserved patient-centered outcomes without widening digital divides, suggesting that human facilitation and primary care integration can effectively mitigate digital exclusion in universal health systems.

In many parts of the world, the promise of digital health is that it can bring specialist care to people who live far from hospitals or cannot easily travel. The idea is that a video call can replace a long bus ride, saving time and money while keeping medical advice accessible. However, there is a hidden risk in this shift. If a patient must operate the technology themselves—navigating a complex app, troubleshooting a connection, or typing on a small screen—those with less formal education or less experience with computers might be left behind. This creates a new kind of barrier, where the very tool meant to help actually widens the gap between those who can use it and those who cannot. The question for health systems is whether they can design digital services that include everyone, or if they will inevitably favor the most tech-savvy.
A team of researchers in Brazil set out to test a specific solution to this problem within the country's public health system, which serves over 200 million people. They focused on adults with type 2 diabetes, a condition that requires regular check-ins with specialists. Instead of asking patients to manage the technology alone, the researchers designed a system where a trained nurse was always present to help. The nurse would set up the video call, handle the technical details, and guide the patient through the visit, acting as a bridge between the person and the screen. This approach was tested in a large, real-world trial involving nearly 280 adults in the city of Joinville. The goal was to see if this "nurse-assisted" teleconsultation could provide an experience just as good as, or better than, going to the specialist's office in person, and whether it worked equally well for people with very little formal schooling compared to those with more education.
The study compared two groups of patients. One group traveled to their local primary care clinic, where a nurse helped them connect via video to a specialist doctor. The other group traveled to a specialist clinic to see the same type of doctor face-to-face. Both groups received the same medical care, including prescriptions and lab tests, but the way they met the doctor was different. The researchers were particularly interested in how the patients felt about the process. They asked specific questions about satisfaction with their sleep, their social life, their ability to work, and their overall health experience. They also measured how easy the technology was to use, paying close attention to whether education levels made a difference in how people handled the digital visits.
The results showed that the nurse-assisted approach worked remarkably well. In fact, patients who used the video system with a nurse's help reported being just as satisfied as those who saw the doctor in person. For one specific aspect of life, the digital group actually did better: dissatisfaction with sleep dropped significantly. In the group that saw the doctor in person, about 27 percent of people were unhappy with their sleep, whereas in the nurse-assisted video group, that number fell to roughly 14 percent. This suggests that removing the stress of traveling to a distant clinic may have helped patients rest better. Overall, the patients felt the care they received was good, and the system did not seem to exclude anyone based on their education.
Perhaps the most important finding concerned the usability of the technology. When asked if the system was easy to use, every single person in the video group said yes. This was true even for the nearly half of the participants who had very little formal education and were considered at high risk of being left behind by digital tools. The presence of the nurse effectively removed the barrier of digital literacy. The study found no evidence that the technology favored the educated over the less educated; instead, the human help provided by the nurses made the digital experience accessible to everyone. This suggests that when a health system builds in human support, digital care does not have to be an exclusive club for the tech-savvy.
However, the study also highlighted areas where the method of consultation did not solve deep-seated problems. Even with the nurse's help, a large number of patients in both groups remained dissatisfied with their sexual health and their opportunities for physical activity. About 29 percent of people in both the video group and the in-person group reported being unhappy with these aspects of their care. The researchers noted that these are complex issues that likely require more than just a change in how the doctor and patient meet. They point to a need for broader changes in how the health system addresses these topics, rather than just switching from a face-to-face meeting to a video call.
The study also looked closely at whether the digital system worked differently for people with different levels of education. While the numbers were too small to prove a definitive difference, the patterns suggested that the nurse-assisted model worked well for everyone. In the group with the lowest education levels, there was zero reported dissatisfaction with the overall experience in the video group, compared to a small but noticeable amount of dissatisfaction in the in-person group. Although the researchers caution that this specific comparison needs more study to confirm, it offers a hopeful sign that with the right design, digital health can be inclusive.
Ultimately, this research demonstrates that digital health does not have to leave the most vulnerable people behind. By placing a trained nurse in the room to handle the technology, the researchers turned a potentially difficult digital experience into a smooth, human-centered one. The study suggests that the key to equitable digital care is not just having the technology, but having a person there to guide the patient through it. While the video visits did not fix every health problem, they successfully preserved the quality of the patient experience and ensured that people with less formal education could access specialist care just as easily as everyone else. The findings offer a practical blueprint for health systems everywhere: if you want to expand digital care fairly, you must design it with human help at its core.
