I assume you are talking about General Systems Theory -- and not one of the many specific nursing theories based on General Systems Theory and/or Open Systems Theory. The general systems theory was initially proposed and developed by a biologist, Ludwig von Bertalanffy (1901-1972) in the 1950’s. The Neuman Systems Model views the client as an open system that responds to stressors in the environment. She grew up on a farm which later encouraged her to help people who are in need. He would like to impart the importance of understanding nursing theories that he hopes to be translated successfully to practice. Each patient has evolved a normal range of responses to the environment referred to as the normal line of defense. Nursing services delivery theory: An open system approach. systems theory terminology. When system needs are met, optimal wellness exists. Angelo aims to build a good foundation for aspiring nurses. The normal line of defense can be used as a standard from which to measure health deviation. The Systems Model of health is equated with wellness, and defined as “the condition in which all parts and subparts, or variables, are in harmony with the whole of the client.” The client system moves toward illness and death when more energy is needed than what’s available. It focuses on the response of the patient system to actual or potential environmental stressors and the maintenance of the client system’s stability through primary, secondary, and tertiary nursing prevention intervention to reduce stressors. If adequate energy is available, the system will be reconstituted with the normal line of defense restored at, below, or above its previous level. 3 nursing, too, interesting benefits might be anticipated if nursing theorists were to examine more recent systems theory and make use of it as a basis for reflection. The major strength of the Neuman Systems Model is its flexibility for use in all areas of nursing – administration, education, and practice. (See Figure 1.) Wellness is on a continuum of available energy to support the system in an optimal state of system stability. The emphasis on primary prevention, including health promotion, is specific to this model. The model defines nursing as “actions which assists individuals, families and groups to maintain a maximum level of wellness, and the primary aim is stability of the patient-client system, through nursing interventions to reduce stressors.” Neuman also says the nurse’s perception must be assessed in addition to the patient’s, since the nurse’s perception will influence the care plan he or she sets up for the patient. Primary prevention occurs before the stressor invades the system; secondary prevention occurs after the system has reacted to an invading stressor; tertiary prevention occurs after secondary prevention as reconstitution is being established. Each patient has implicit internal resistance factors known as LOR, which function to stabilize and realign the patient to the usual state of wellness. The environment has three components: the internal, which exists within the client system; the external, which exists outside the client system; and the created, which is an environment that is created and developed unconsciously by the client, and is symbolic of system wholeness. Primary prevention is applied in patient assessment and intervention, in identification and reduction of possible or actual risk factors. The client as a system is in dynamic, constant energy exchange with the environment. As noted in the Learning Resources, systems theory provides a meaningful and beneficial means of examining challenges in health care organizations. The cells within … The subsystems are physiological, which refers to the physiochemical structure and function of the body; psychological, which refers to mental processes and emotions; socio-cultural, which refers to relationships, and social/cultural expectations and activities; spiritual, which refers to the influence of spiritual beliefs; and developmental, which refers to those processes related to development over the lifespan. Systems theory 1. Reflect on your organization or one with which you are familiar. Nursing interventions are aimed at helping the system adapt or adjust and to retain, restore, or maintain some degree of stability between and among the client system variables and environmental stressors with a focus on conserving energy. The theory focuses on the response of the patient system to actual or potential environmental stressors and the use of primary, secondary, and tertiary nursing prevention intervention for retention, attainment, and maintenance of patient system wellness. These forces include the intrapersonal, interpersonal, and extra-personal stressors, which can affect the person’s normal line of defense and so can affect the stability of the system. A process of energy conservation that increases organization and complexity, moving the system toward stability or a higher degree of wellness. Many known, unknown, and universal stressors exist. The patient is in dynamic, constant energy exchange with the environment. With such, new nursing interventions as to the provision of needed energy of the client can be conceptualized. influences. Each client/client system has evolved a normal range of responses to the environment that is referred to as a normal line of defense. This article describes the most typical characteristics of complex adaptive systems (CAS) theory and how it works in healthcare organizations and nursing practice. Betty Neuman describes the Neuman Systems Modelas “a unique, open-system-based perspective that provides a unifying focus for approaching a wide range of concerns. It was established as a science by Ludwig von Bertalanffy, Anatol Rapoport, Kenneth E. Boulding, William Ross Ashby, Margaret Mead, Gregory Bateson and others in … Focus especially on the information presented in Table 1 (p. 2831) and Figure 2 (p. 2833).Reflect on your organization or one with which you are familiar. The particular interrelationships of client variables at any point in time can affect the degree to which a client is protected by the flexible line of defense against possible reaction to stressors. Neuman has presented a view of the client that is equally applicable to an individual, a family, a group, a community, or any other aggregate. A stressor is any phenomenon that might penetrate both the flexible and normal lines of defense, resulting in either a positive or negative outcome.

The human is in constant change, moving toward a dynamic state of system stability or toward illness of varying degrees. Systems theory offers a framework for quality improvement (QI) in healthcare systems because systems theory supports systems thinking. Angelo Gonzalo earned his Nursing degree in the year 2010 and continued his studies at St. Paul University Manila taking up Masters of Arts in Nursing Major in Clinical Management. Throughout the years, she earned many awards and honors including several honorary doctorates and was an honorary member of the American Academy of Nursing. Her use of the concept of entropy is inconsistent with the characteristics of entropy which is closed, rather than an open system. These factors include the system variables, genetic features, and strengths and weaknesses of the system parts. Systems thinking isn't new to nursing. Systems theory may be considered as a specialization of systems thinking and a generalization of systems science. It focuses on keeping stressors and the stress response from having a detrimental effect on the body. Further revisions were made in later editions. Neuman views the individual client holistically and considers the variables simultaneously and comprehensively. Systems are … Her mother was a self-educated midwife, that led the young Neuman to be always influenced by the commitment that took her away from home from time to time.
