This is a descriptive-exploratory study conducted with 411 patients and their companions in order to examine their perception and level of satisfaction regarding the meeting of their care needs during hospitalization and to verify the association of this level with the socio-demographic variables and the characteristics of hospitalization and unit. A self-administered instrument was used for data collection. The patient/companion satisfaction score ranged from 3.6(0.4) to 4.6(0.4). The emotional and spiritual (81 and 82%), safety (83 and 67%), and care needs (87 and 61%) were the most met. An association was found between satisfaction and some socio-demographic variables and characteristics of hospitalization. Overall, patients and their companions were satisfied with their care; however, some important areas presented satisfaction deficits requiring more attention from the nursing team.
