Referentes teóricos que sustentan un sistema de vigilancia de eventos adversos en unidades de cuidados intensivos.

The study of the theoretical foundations allows delving into the processes associated with assistance in progressive care. The objective of this research is to analyze the theoretical references for the design of a surveillance system for adverse events in intensive care units. For this purpose, a bibliographic review was carried out, from the referent, advanced for its time, by Florence Nightingale; going through the theoretical assumptions of Madeleine Leininger; to the connection with Reason's Swiss Cheese model and Ludwig Von Bertalanffy's general systems theory. The integration of these theories was of great value for the approach of a scientifically based surveillance system, applicable with a view to achieving other products that are later supported in practice.
