Health Care System Model

(1972,1974,1980,

1982,1989)

Person/Client:

Open system consisting of a basic structure or central core of survival factors surrounded by concentric rings that are bounded by lines of resistance , a normal line of defense, and a flexible line of defense. The total person is a composite of physiologic, psychologic, sociocultural, and developmental variables.

Environment:

Both internal and external environments exists and a person maintains varying degrees of harmony and balance between them. It is all factors affecting and affected by the system.

Health:

Wellness is the condition in which all parts and sub-parts of an individual are in harmony with the whole system. Wholeness is based on interrelationships of variables that determine the resistance of an individual to any stressor. Illness indicates lack of harmony among the parts and sub-parts of the system of the individual. Health is viewed as a point along a continuum from wellness to illness; health is dynamic. Optimal wellness or stability indicates that all a person’s needs are being met. A reduced state of wellness is the result of unmet systemic needs. The individual is in a dynamic state of wellness-illness, in varying degrees, at any given time.

 

Neuman’s Health Care Systems Model

Betty Neuman’s systems model, first published in 1972, is based on the individuals relationship to stress, the reaction to it, and reconstitution factors that are dynamic in nature. Reconstitution is the state of adaptation to stressors.

Neuman views the client as an open system consisting of a basic structure or central core of energy sources surrounded by two concentric boundaries or rings referred to as lines of resistance. The two lines of resistance represent internal factors that help the client defend against a stressor. The inner or normal line of defense represents the person’s state of equilibrium of the state of adaptation developed and maintained over timeĀ  and considered normal for that person. The flexible line of defense is dynamic and can be rapidly altered over a short period of time. It is a protective buffer that prevents stressors from penetratingĀ  the normal line of defense.

The nurse’s focus is all the variables affecting an individual’s response to stressors. Nursing interventions are carried out on three preventive levels:

1. Primary prevention identifies risk factors, attempts to eliminate the stressor, and focuses on protecting the normal line of defense and strengthening the flexible line of defense. A reaction has not yet occurred, but the degree of risk is known.

2. Secondary prevention relates to interventions or active treatment initiated after symptoms have occurred. The focus is to strengthen internal lines of resistance, reduce the reaction, and increase resistance factors.

3. Tertiary prevention refers to intervention following that in the secondary stage. It focuses on readaptation and stability and protects reconstitution or return to wellness follwing treatment. The nurse emphasizes educating the client in strengthening resistance to stressors and ways to help prevent recurrence of reaction or regression.

Betty Neuman’s model of nursing has been widely accepted by the nursing community, nationally and internationally. it is applicable to a variety of nursing practice settings involving individuals, families, groups, and communities.
