OBJECTIVE: To describe the current scientific literature about permanent and continuing nursing education in intensive care units worldwide. METHODS: This is an integrative literature review, using the Cumulative Index to Nursing and Allied Health Literature, the Regional Portal of the Virtual Health Library, and the PubMed Portal, carrying out the data analysis based on Laurence Bardin's theory of Content. RESULTS: In total, 26 articles were divided into four categories denominated - Permanent Education in Health Contemplating Nursing Learning Needs; Effects of Permanent Education in Health on Professional Practice and Quality of Care, Perceptions on Permanent Education and its Importance in Intensivist Nursing; and Strategies and Results of Permanent Health Education in Intensive Care. CONCLUSION: There are few studies published specifically on nursing health education in intensive care, and many works suggest that more research and education actions should be carried out for this audience, aimed at improving evidence-based practices and quality of intensivist nursing management.
