São Paulo: Nursing School, University of São Paulo; 2012 This study is placed in the health caring field and its thematic refers to the evaluation of child's health care in the city of Colombo-Paraná. Its object of study is the performance of Basic Health Units (UBS) and the Strategy Units of Family Health (USF). The study aims: to evaluate both the presence and extention of the essential attributes and derivates relative to the APS regarding the care given at the primary care of the children at their family perspective, and to compare the UBS and USF attributes performance. This research subjects were responsible for 17-22 month-old children, registered and assiduous to the city health units activities, in a random sample of 482 people: 247 from the Basic Units and 235 from the ESF units. Data was collected at their houses and the Primary Care Assessment Tool (PCATool), children's version, was used. PCATool was validated in 2008 and used by the Brazilian Health Ministry as reference. Interviews were held between June and July 2012. The samples, using the software Statistica 10.1, included the t student test to compare the quantitative variants and the qui-square test, for qualitative variants; Crombach's Alfa was obtained in order to verify the intern consistency of instrument items for each one of the attributes and total instrument. A pilot study has been performed as to guarantee both the instrument and interview efficacy. This study followed Resolution 196-96 from Research Ethics National Council. The research revealed that the ESF units obtained scores higher than the minimum required in Affiliation, Coordination, Integrality, Familiar Orientation and Accessibility, half the studied attributes, indicating that the ones responsible for the children who attend those units refer to having more frequent access to health services, use more often the health unit as an entrance door to the health system, establish more constantly an integrated service and recognize the professional valorization regarding the bond with the family. Regarding the UBS, all the scores were below ideal for the APS, indicating that those units seem to struggle to bond with its users and recognizing them as part of a community. It has been observed that assessment works play a fundamental role in perfecting the intervention axis aiming at joining the Health Ministry focus, which is to transform health services into Primary Care. In that city it has been concluded that the ESF units are closer to APS directress than UBS, however it is necessary to revise the child assistance related actions in order to reach consonance with the APS attributes at both units.
