Network transversality: matrix support in the decentralization of counseling and rapid testing for HIV, syphilis, and hepatitis Transversalizando a rede: o matriciamento na descentralização do aconselhamento e teste rápido para HIV, sífilis e hepatites

The aim of this research was to investigate how the decentralization of counseling and rapid testing for HIV (Human Immunodeficiency Virus), syphilis, and hepatitis B and C have been implemented in the city of Porto Alegre, Brazil, using matrix support with Primary Health Care teams. It is a qualitative study, in which eight matrix supporters were interviewed. Positive aspects include training of Primary Health Care professionals, interconsultation, supervision, and visits. Such experiences point out the potentiality of more horizontal work between primary and specialized levels of care. Negative aspects include the emphasis on the technical aspect of the test and the discontinuity of matrix support.
