The public policies adopted by the Unified Health System (SUS) in Brazil have gone through successive transformations, striving to reassert health as a universal right. The user acceptance of the guidelines of the National Humanization Policy for Care and Management of the SUS - Humanize SUS - is taking shape and relevance in Primary Healthcare (PHC) to ensure humanized access and resolution of the health demands of users and communities in Brazil. A critical analysis of the bibliographical output in Brazil from 1989 to 2009 was conducted regarding acceptance of implementation and qualification of SUS in PHC. The databases consulted were SciELO, Lilacs and Medline. The results revealed progress in broadening access to PHC services and health professionals more sensitive to the needs of users and communities. However, lack of coordination in integrated networks, excess demand, the hegemonic biomedical model, lack of training and democratic and reflexive spaces to reorganize the work process have been raising increasingly more incisive questions about the potential of this guideline for the implementation and qualification of SUS.
