[Government regulation of the private health care market in Brazil: a history of disputes].

This paper reconstructs the dispute between the main social actors with direct interests in the regulation of private health care in Brazil during the period immediately prior to the passage of Act 9.656/98, highlighting the divergences between these actors in relation to 28 central topics for shaping the regulatory framework prevailing in the country since 1998. The material used in the description and systematization of the positions in the regulatory dispute resulted from an empirical, descriptive, comparative study based on document analysis and interviews with key actors. The study systematizes the main points of controversy and consensus among the various actors, particularly highlighting the many points of agreement between proposals by medical organizations and those of users' organizations and consumer defense institutes, thereby suggesting the possibility of establishing an ethical and political bloc committed to the defense of improved health care as opposed to sheer market logic.
