Impact of the identified nursing theory on evidence-based practice.

Nursing Theory: The Neuman Systems Model The Neuman Systems Model (NSM) is a grand nursing theory that was developed by Betty Neuman in the 1970s. The NSM is a holistic model that views the person as a dynamic system that is constantly interacting with the environment. The model identifies four major variables that can affect the person's health:

• Internal variables: These are the person's physical, psychological, and sociocultural characteristics.
• External variables: These are the physical, social, and emotional forces in the environment.
• Neuman's lines of defense: These are the person's natural defenses against stressors.
• Neuman's lines of resistance: These are the person's adaptive mechanisms that help to maintain stability in the face of stressors.

The NSM has four tenets:

1. The person is a total system.
2. The person is in constant interaction with the environment.
3. The person has lines of defense and resistance.
4. The person's response to stressors is predictable.

The NSM can be applied to a variety of nursing settings and populations. It can be used to assess a person's health status, to develop nursing interventions, and to evaluate the effectiveness of nursing care. The NSM has had a significant impact on evidence-based practice. The model's focus on the person as a total system has helped nurses to appreciate the complexity of the factors that can affect a person's health. The model's emphasis on prevention has also led to the development of a number of evidence-based nursing interventions. For example, the NSM has been used to develop evidence-based interventions for reducing stress, promoting health, and managing chronic illness. The model has also been used to develop nursing education programs and to guide nursing research. The NSM is a valuable tool for nurses who are committed to providing evidence-based care. The model's holistic perspective and its focus on prevention make it a powerful tool for promoting health and well-being. Other Nursing Theories In addition to the Neuman Systems Model, there are many other nursing theories that can be used to guide nursing practice. Some of the most well-known nursing theories include:

• The Roy Adaptation Model
• The Orem Self-Care Deficit Theory
• The Henderson Basic Human Needs Theory
• The Leininger Culture Care Diversity and Universality Theory
• The Parse Theory of Human Becoming

These theories provide nurses with a framework for understanding the complexities of the human experience and for providing holistic, evidence-based care. The Impact of Nursing Theories on Evidence-Based Practice Nursing theories have had a significant impact on evidence-based practice. The theories provide nurses with a framework for understanding the research literature and for translating research findings into practice. The theories also help nurses to identify the gaps in the research literature and to prioritize areas for future research. In addition, nursing theories can help nurses to communicate more effectively with other healthcare professionals. By using the same language and concepts, nurses can ensure that they are providing consistent and high-quality care. Conclusion Nursing theories are essential tools for nurses who are committed to providing evidence-based care. The theories provide nurses with a framework for understanding the complexities of the human experience and for providing holistic, evidence-based care. Nursing theories also help nurses to communicate more effectively with other healthcare professionals.
