According to Von Bertalanffy, systems are characterized as:

The characterization of systems as open and evolving, as proposed by Von Bertalanffy, is grounded in the concept of General Systems Theory. This theory emphasizes the idea that systems interact with their environments and are influenced by external factors. An open system exchanges energy, information, and materials with its surroundings, which allows for adaptation and change over time.

In the context of nursing and healthcare, acknowledging that systems are open and evolving highlights the complex interactions between patients, families, healthcare providers, and the environment. This perspective encourages a holistic approach to patient care, recognizing that various factors, such as social, cultural, and environmental influences, play a crucial role in health and wellness.

By understanding systems as evolving rather than static, healthcare professionals can better adapt to changes in patient needs, technological advancements, and shifts in healthcare policies, ultimately leading to improved outcomes.
