Digital health ecosystem in the municipality of Rio de Janeiro, Brazil: the experience of the creation of the minhasaude.rio application

This article describes the digital transformation trajectory of the Municipal Health Department of Rio de Janeiro (SMS-Rio), leading to the creation of minhasaude.rio application. The study was divided into two phases: document analysis and systematization of the app’s development process, which was structured into three stages: information digitization, integration and construction of the health data lake, and creation of the app. Since its launch, the number of registered users has increased, with information on regulatory information, appointment scheduling, exams, and vaccination history being the most widely accessed. Integration with the federal government’s gov.br for first-time access now accounts for 25% of new users. The users are predominantly black/brown, women, between the ages of 18 and 69 years. In 2025, 39.2% of the users reported being extremely satisfied. The case illustrates the digital maturity and modernization of healthcare services, featuring local solutions that enable personalized care and seamless data integration. The updates and public involvement are key elements for the success of the implemented technology.
