Abstract: Accreditation has been used by many countries to encourage improvements in hospital service quality.
In Brazil, the dissemination of the Brazilian Accreditation System is a responsibility of the National Accreditation
Organization (ONA). Studies on the impact of hospital accreditation have aroused the interest of the academic
community. This article aims to analyze the impact of accreditation on organizational performance of hospitals.
A qualitative research approach and the method of multiple cases were adopted for this study. Cases were performed
in six accredited hospitals in the state of Sao Paulo. One of the main conclusions of this study is that hospital
accreditation promotes improvements related to the process management, customer safety, and development of
healthcare professionals. This paper contributes to expand the studies on accreditation in Brazil.
