The Orem Self-Care Model is a nursing theory developed by Dorothea Orem that emphasizes the importance of self-care in maintaining health and well-being. It suggests that individuals can take responsibility for their own health through self-care activities, which include personal hygiene, nutrition, and exercise. The model identifies three interrelated concepts: self-care, self-care deficit, and nursing systems. In this model, a self-care deficit occurs when individuals are unable to meet their own self-care needs due to various factors, such as illness or lack of knowledge. Nurses play a crucial role in assessing these deficits and providing support through education, guidance, and direct care, enabling individuals to regain their ability to care for themselves effectively.
