This qualitative study, based on social survey, aimed at understanding actions carried out in mental health in nine cities of the 10th Health District of the Health Care Module of Cascavel, Paraná, Brazil. Nine municipal health secretaries participated in a semi-structured interview carried out between July and September, 2004. Collective Subject Discourse (CSD) was used to analyze the data. Five CSD and three meaning-generating themes (service reorganization, home visits, and prevention) were identified. The present article discusses theme 1--service reorganization, which should include diverse mental health care modes integrated to the regional basic health care network.
