Using the translation of knowledge as a theoretical reference, this research was conducted with the homeless population, health professionals and health administrators. Funded by FAPESC in a PPSUS Program. PPSUS é a fund directed to strengthen our public health system - SUS. The homeless population is growing worldwide, especially in metropolises or big cities. The access of this population to health services and the effectiveness of public health programs designed for them was the scope of our research. We get started with a bibliography review using PRISMA methodology, checking what was produced about health programs and the homeless population. We included the central policies in Countries such as the USA, England, Colombia and Mexico to compare with Brazilian policy on the homeless population and all the scientific productions about this theme. We developed the evaluative matrix to conduct our investigation based on these results. An evaluative matrix is a strategic device to help a team, a program, or an organisation clearly express the effects that its social interventions intend to generate and the associated indicators. This matrix was validated by experts and with members of national groups or non-governmental organisations of the homeless population. These members usually live on the streets, so their analyses of health questions and needs, helped us to elaborate the interview guide; it was conducted in two of the biggest cities (Joiville and Florianópolis) in our state Santa Catarina in the south region of Brazil. The results show a lack of what is offered and what precisely the homeless population can access, mainly because the health
professionals are not conscious of the peculiarities of this population, and bureaucratic requirements make it difficult and are not sustainable. The final product of this research is a line care guide for discussion in our state and country discussing the role of nursing in welcoming and monitoring the health of this population and proposing the effectiveness of public policies already developed but not precisely improving the health of vulnerable people.
