ABSTRACT:
In Brazil, there is a culture of data transparency, particularly in health. The Ministry of Health, through DATASUS, provides a data tabulator known as TABNET, which offers information that can support analyses and evidence-based decision-making. This culture has inspired replication across states and municipalities. Niterói, a city in the state of Rio de Janeiro, has developed its own data tabulator called TABNIT. TABNIT aims to innovate by presenting a data tabulator structured in the R programming language, enabling extraction of anonymized data at the neighborhood level, as well as the creation of maps and charts. It also includes pre-calculated indicators. The proposal is to create a publicly accessible tabulator that can be freely replicated. TABNIT was developed using the shiny package in RStudio (version 4.4.1). The project integrates four scripts: • global.R: processes databases, structuring them for tabulation. • ui.R: defines the user interface, including available buttons, color palettes. • server.R: executes the functions defined in ui.R. For example, if ui.R specifies a box for charts and maps, server.R generates them. • app.R: runs the tabulator based on ui.R and server.R. This structure follows the standard framework of a shiny application. Currently, TABNIT is undergoing validation and is not yet publicly available. It is expected to be launched in the first semester of 2026, with its scripts made accessible on GitHub upon completion of this process. TABNIT will provide data on mortality, births, population demographics, health conditions such as tuberculosis, syphilis, leprosy, dengue, respiratory syndromes, nutritional status and dietary intake. A municipal-level data tabulator is of great importance for local health management, as it will publicly provide health data by neighborhood and resident population. This addresses a limitation of TABNET, which only offers data at the state level and does not allow for more specific stratifications within Brazilian cities.
