title: [Quality and health systems].
abstract: The purpose of this paper is to demonstrate, through an example, the impact of health systems in populations in terms of access and quality. One of the most telling examples is the issue of maternal deaths in which both variables, accessibility and quality, are expressed starkly, for better or for worse. Before that, it is necessary to consider three principles as a framework of reference. Hence, from the premises will look at the example and from there reach some conclusions on the topic.
