Telemedicine for COVID-19 management in Brazil: outcomes and health system implications from a prospective cohort study.
Article in The journal of venomous animals and toxins including tropical diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The COVID-19 pandemic exposed vulnerabilities in traditional disease surveillance systems, particularly in data reporting and contact tracing. Telemedicine emerged as a promising approach to expand remote access to healthcare. This study aimed to evaluate a newly implemented telemedicine system designed to manage patients with COVID-19, reduce hospital overload, enable early case detection and isolation, ensure rapid response to clinical deterioration, simplify medical records, and provide ongoing patient support. Methods: A prospective cohort study was conducted using the E-care telemedicine system to assist adult patients presenting with COVID-19 symptoms at a Brazilian university between June 2021 and June 2024. Results: The E-care system delivered care to 6,129 patients, predominantly female, white university students. Physicians attended over 80% (4,903/6,129) of patients and prescribed medications to nearly 28% (1,411/5,041). Medical certificates for time off work were issued to 43% (2,635/6,129) of participants. COVID-19 tests were recommended for approximately 24% of patients, with a positivity rate above 81% among those who returned results. Only 66 patients (1.2%) required in-person care, and no COVID-19-related deaths were reported. Patient satisfaction was high, with 96% (5,584/6,129) expressing satisfaction or high satisfaction with the service. Conclusions: This study provides robust evidence supporting the successful implementation of a telemedicine system for managing COVID-19 cases. The large number of users highlights an unmet demand for virtual healthcare. Telemedicine was rapidly adopted, achieved high patient satisfaction, and contributed to reducing hospital burden, promoting early detection, and minimizing in-person consultations. These findings reinforce the value of telemedicine as an essential tool for health systems and policymakers to strengthen care delivery beyond the pandemic.
