The effects of a people-centred model on longitudinality of care and utilization pattern of healthcare services--Brazilian evidence.

Brazil is experiencing a time of change in pattern of care: from 'traditional' to Family Health Strategy (FHS), a model guided by the principles of people, family and community-centred medicine. The heterogeneity in care currently offered affects the primary care impact. This study aims to evaluate the longitudinality of care and correlate this primary care principle to the utilization pattern of care among patients hospitalized due to preventable conditions, comparing the two care models currently offered in Brazil. It is a cross-sectional, analytical and descriptive study with a quantitative approach. The sample consisted of 501 patients from 0 to 14 years old. Data was collected in 2011 and the Primary Care Assessment Tool (PCATool-Brazil) child version was used. Bivariate and multivariate analyses were performed including patient-related variables (age, maternal education, income and type of diagnosis) and care model. From the hospitalizations occurred during the period, 65.2% were Ambulatory Care Sensitive Conditions. Patients evaluated 'longitudinality' as regular. Both the care continuity dimension and the utilization pattern of care services showed a link with the care model offered. Findings suggest that the FHS care model, based on the assumptions of people-centred medicine, was associated with better ratings of care continuity, which was reflected in a more appropriate utilization pattern of care services.
