Leininger’s theory or the Culture Care theory, involves knowing and understanding cultural differences in the area of Nursing care practice. Her theory emphasizes that different cultures requires different but effective care. This knowledge provides culturally specific meanings and expression in relation to care and health. Without this theory an array of ineffective care can easily be presented.For example; A patient’s diet can be of great significance in their care. Not having thoroughly thought out culturally appropriate meals prepared for the sick can ultimately change the trajectory of how effective an outcome will be. Culturally competent nursing care helps ensure patient satisfaction an positive outcomes.Every race or culture may perceive or demonstrate the effect of pain differently. She developed a theory and research method designed to guide nurses to (a) understand cultural similarities and differences in how people care for themselves and others during health, illness, disability, dying, and death, and (b) provide culturally congruent, competent, and sensitive care. Wehbe-Alamah, Hilba B) Leininger’s Culture Care Diversity and Universality Theory: Classic and New Contributions. As written in The Parents’ Cultural Care Towards Promoting Child Development; A quantitative approach that was carried out with parents of children below five years old, who were registered in a healthcare service from Picos city, Piaui State, Brazil.Nurses are expected to explore even more the probable performance according to each child’s age and considering the child development stage, moreover, respecting the cultural care provided by their parents.The conception model was designed to guide Nursing practice therefore, Without understanding one’s culture, the risks of inadequate care arises. Conceptual modes are important in guiding the development of the discipline of nursing. Studies continue to show that patient satisfaction scores especially in the Hospital environment grossly increases when close attention and consideration is give to the Patient’s culture an their ways of life.Leiniger’s model provides three action modes nurses can use to help bridge care and provide care to someone with respect to their individual beliefs, cultural background, and values.These modes are all used today in a variety of clinical settings.
