Methods: We searched clinical decision-making websites, guidelines, professional association websites, evidence-based literature resources, and databases for guidelines, evidence summaries, best practices, systematic reviews and expert consensus on the prevention and nursing of Pressure Injury in critical care children. The JBI evidence appraisal and recommendation system was used to evaluate the quality of studies and the level of evidences.
