The objective of this study is to know which methodologies and databases used in articles treat variables, such as efficiency and costs in the hospital segment and their relationship with the concentration of American organizations. The quantitative methodologies used were, by order of preference, the multivariate statistical analysis and the econometric analysis. The most used data basis was the Annual Report of the American Hospital Association (AHA), followed by the data made available by insurance companies that have long lasting relationships with the hospitals analyzed, besides the specific case studies. Finally, it was observed that the concentration in the sector is reflected in the reduction in terms of competition and efficiency gains, notably in the first year after the fusion, which does not mean that there was reduction in the prices charged by the hospitals.
