The purpose of this study was to implement the Nursing Care Systematization--Sistematização da Assistência de Enfermagem (SAE)--with Wanda Aguiar Horta's Theory of Basic Human Necessities and the North American Nursing Diagnosis Association's (NANDA) Nursing Diagnosis as its references. The starting point was the evaluation of the knowledge of the nursing team about the SAE, including their participation in this process. This is a qualitative study, performed in the Intensive Care Unit in a hospital in the city of Brusque, Santa Catarina, from October, 2006 to March, 2007. It was observed that the nursing professionals know little about SAE, but they are greatly interested in learning and developing it in their daily practice. In conclusion, it was possible to execute the healthcare systematization in an easy way, with the use of simple brochures that provided all the necessary information for the qualified development of nursing care.
