SIVEIN - Sistema de Informação Vacinal em terras indígenas: tecnologia e dados para a saúde indígena no norte do Tocantins

Abstract

Vaccination is one of the most effective public health strategies for preventing vaccine-preventable diseases, especially among vulnerable populations such as Indigenous peoples. At the Indigenous Health Base Pole (PBI) of Tocantinópolis-TO, vaccination coverage monitoring and dose scheduling are performed manually, a process that is time-consuming, error-prone and limits strategic planning. This work develops and presents SIVEIN, a web-based information system built to automate the processing, analysis and visualization of vaccination data from the Brazilian National Immunization Program Information System (SI-PNI). The study includes requirements elicitation, system architecture modeling, development of an API for data processing and the construction of an interactive interface that generates indicators such as vaccination coverage and dose scheduling for children under 12 months. The system was validated with Indigenous health professionals using the Technology Acceptance Model (TAM), showing high perceived usefulness, ease of use and intention to adopt. The results demonstrate that SIVEIN enhances vaccination monitoring, reduces manual workload and strengthens planning within the PBI of Tocantinópolis-TO, representing a significant advancement for Indigenous health information management.
