Understanding matrix support and quality certification results in the areas of care for women, care for children, hypertension and diabetes as well as mental health

This article aims to present the distribution of matrix support (MS) in Brazil and identify relations between MS activities and PMAQ-AB certification results. Two multiple logistic regression models were run. MS activities in primary care are significant, although uneven. There is a positive association between the level of support and result obtained in certification. High degrees of MS correspond to the probabilities of 89%, 80%, 89% and 63% that teams obtain better certification on attention to woman, child, hypertension and diabetes, and to mental health, respectively. MS has progressively helped to improve primary care in Brazil.
