From a personal experience added to the construction of academic knowledge, the desire to expand knowledge about the work of the hospital psychologist based on the Person-Centered Approach (PCA), in Brazil. In this sense, this research, with a qualitative approach, aims to understand the ways of acting of these professionals, as well as to analyze the discussions and notes they make during their practices. For this, an exploratory documentary research was carried out, which used as methodology the Systematic Literature Review (RSL). Data were collected in the databases SciELO, Periódicos CAPES, BVS Brasil, Revista Gestáltica, NUFEN, Redalyc. Grey Literature was also used to map other data sources, such as the electronic portal Encontro ACP and to include references indicated by researchers of this approach, who are appointed as experts. We used the qualitative descriptive analysis, as well as the theoretical framework of the PCA to understand the results. These outline the conduct of the psychologist based on the PCA in the health/hospital context, where he sees it being possible to act in different spaces within the institution, with different audiences and psychotherapeutic formats, making it possible to assist those involved in the context to ensure a humanized performance, based on the assumptions of the PCA.
