The healthcare sector is by definition an interdisciplinary field of action that aims to promote, recover, and above all, maintain the health of a population. To achieve this, the state should develop actions and provide resources, as stipulated in Article 196 of the 1988 Constitution. The Millennium Development Goals (MDGs) are aimed at improving the quality of life of individuals by 2030. These include MDG 3 - Health and Well-being and MDG 10 - Reduction of Inequalities. For the objective of achieving health and well-being, reducing inequalities in living conditions and access to services is essential. It is increasingly important to analyze and intervene in living conditions or health determinants. The use of technology, especially informatics, can be a breakthrough in this regard, although it can also widen the gap between different regions. In Brazil, starting in 2023, there will be a new configuration of the Unified Health System (SUS) due to the COVID pandemic, and access considerations will have to be refocused.
