Growth, centralization, and financialization of Diagnostic and Therapeutic Support Services (SADT) in Brazil: a study of selected companies from 2008 to 2016

This article discusses the dynamics of the Diagnostic and Therapeutic Support Services subsector from 2008 to 2016 in Brazil. Through an exploratory approach, the study aimed to operationalize key concepts from the literature on the pattern of accumulation characterizing contemporary capitalism. The research focused on the activity of six Brazilian diagnostic companies in three main dimensions: (1) net worth; (2) accounting-finance; and (3) policy. The results reveal a subsector experiencing vigorous growth via increases in the volume and prices of the services provided. The evidence corroborates traits of a pattern of financialized accumulation, especially aggressive strategies of mergers and acquisitions by leading companies, with centralization as a result. However, some characteristics associated with the concept of financialization appear not to be relevant. The article also discusses the prospects for competition in activities in the Diagnostic and Therapeutic Support Services subsector and the possible effects for the effort to consolidate Brazilian Unified National Health System (SUS).
