[How should population health be approached? SESPAS Report 2012]

Abstract

The health of the population largely depends on environmental factors, raising the issue of what the role of health professionals, particularly those in public health and primary care, should be in the planning of objectives and actions for improvement. The present article proposes a trajectory, starting with knowledge of the community's strong points in health and its needs, and ending with taking action. This trajectory requires discussion on how information can be transformed into action. We analyze the current situation and its strengths and weaknesses, and make proposals for the entire process: from information to action. Information is more than just the available data gathered from different sources; it is also knowledge of those who belong to the community or are very close to it. This perspective should include both health deficits and health assets. This information should be used not only by health professionals, but by all those in a position to influence the determinants of health. Finally, when considering the actions required to improve the health of a community, we emphasize the benefits of health promotion, in the genuine sense of the term, by reflecting on effectiveness and efficiency. The question of whether the failure of an intervention to improve health is due to the futility of the action, or to be action being undertaken in an inefficient way, is discussed.
