Percecao da cultura organizacional em instituicoes publicas de saude com diferentes modelos de gestao

context: the portuguese health system has been subject to constant reforms that have been achieved without the expected results. considering organizational culture as a variable which can dictate the success of a particular change / reform, and starting from the assumption that it is manageable, knowing about the organizational culture that is prevalent in health facilities seems to be important for those who manage them, primarily during the course of processes of change, such as the implementation of new management models. objective: to identify the type of organizational culture that prevails in public health facilities with different management models. method: a cross-sectional quantitative study, performed with a sample of 671 employees from ten health facilities with different management models: public sector administration model (sector publico administrativo - spa), public enterprise entity model (entidade publica empresarial - epe) and family health unit model (unidade de saude familiar - usf). to identify the perception of organizational culture the organizational culture assessment instrument (ocai) was used; it was translated, adapted and validated by us. results: in the spa and epe models, there is a predominance of hierarchical culture, whereas in usf model clan culture exists. conclusion: the organizational culture that prevails, particularly at hospital level (hierarchical culture), in health facilities, does not seem to be the most appropriate for the philosophy underlying the implementation of new management models, and its functioning. it is considered relevant to extend the study of the perception of organizational culture in each management model of health facilities, and relate it with context variables.
