Field of practice: LARIISA: smart digital solutions to support decision-making in Family Health Strategy management.

The LARIISA collaborators group has been conducting research and development of technological solutions to support decision-making in health systems since 2009. GISSA, a cloud system resulting from the scientific and technological evolution of the LARIISA project, is among the solutions produced. This paper aims to describe the developing trend of GISSA©, a technological tool supporting the Family Health Strategy in northeastern Brazil, pointing out challenges, paths, and potentialities. This is a descriptive and exploratory study, based on secondary sources from the IBGE, INMET, SINAN, SIM, and SINASC, with quantitative analysis based on machine-learning techniques applied to create digital health microservices. Operating in the northeast and southeast regions, GISSA© provides information that qualifies health managers' decision-making process, improving the municipal health system's management.
