The document discusses the spread of Quaternary Prevention (QP) in South America over the past years. QP aims to avoid overmedicalization and protect patients from unnecessary interventions. Working groups have formed in several countries like Argentina, Brazil, and Uruguay to promote QP. They organize seminars, workshops and online forums for discussion. Communication strategies to spread information about QP include websites, blogs, Facebook pages, and Google groups. The movement seems focused on raising awareness of QP among health professionals and encouraging reflection on overmedicalization in clinical practice.
