Theory of Nursing Systems = Orem’s Theory

This is the unifying theory that “subsumes the theory of self-care deficit which subsumes the theory of self-care”

(Orem, 1991, p. 66Orem, 1991, p. 66). The Theory of Nursing Systems attempts to

answer the question “What do nurses do?”

Dorothea Elizabeth OremDorothea Elizabeth Orem

Dorothea Elizabeth Orem (1914 – June 22, 2007), born in Baltimore, Maryland, was a nursing theorist and founder of the Orem model of nursing, or Self Care Deficit Nursing Theory.

In simplest terms, this theory states that nurses have to supply care when the patients cannot provide care to themselves.

Her Theory is about self-care. It's all about the capacity to recover themselves with a little help of Nurses

The nurse determines whether or not there is a legitimate need for nursing care. Is a person able to meet self-care needs? Does a deficit exist? If a deficit exists, then the nurse plans care that identifies what is to be done by whom: the nurse, the client, or other (family or significant other).

Collectively, the actions of all these people are called the nursing system.

Orem’s Theory

Orem identified three types of nursing systems: – wholly compensatory, – partly compensatory, and – supportive-educative.

Orem’s Theory: compensatory nursing system

In the wholly compensatory nursing system, the nurse supports and protects the client, compensates for the client’s inability to care for self, and attempts to provide care for the client. The nurse would use the wholly compensatory nursing system when caring for a newborn or with a client in a postanesthesia care unit who is recovering from surgery. Both of these clients are completely unable to provide self-care.

Orem’s Theory: the partly compensatory nursing system

In the partly compensatory nursing system, both the nurse and client perform care measures. For example, the nurse can assist the postoperative client to ambulate. The nurse may bring in a meal tray for the client who is able to feed self. The nurse compensates for what the client cannot do. The client is able to perform selected self-care activities but also accepts care performed by the nurse for needs the client is unable to meet independently.

Orem’s Theory: the supportive-educative nursing system

In the supportive-educative nursing system, the nurse’s actions are to help clients develop their own self-care abilities through knowledge, support, and encouragement. Clients must learn and perform their own self-care activities. The supportive-educative nursing system is being used when a nurse guides a new mother to breastfeed her baby.

Interpretation of Orem’s theory through Mandala art

Interpretation of Orem’s theory through Mandala art

Self care: The flag design represents independence. People are independent when they do what they can to maintain life, health, and well-being.

Self-care deficit: The handicap symbol, made into a compass, symbolizes dependency of the patient coupled with the guidance, direction, and support of the nurse.

Nursing systems: Represented by the fish and hook because it reminds me of the saying: "Give a man a fish, feed him for a day. Teach a man to fish, feed him for a lifetime." The nurse compensates for what the patient cannot do for himself while teaching how to care for himself.

Nursing Process: All the symbols are encompassed in a larger symbol- an apothecary symbol. This symbol represents diagnosis and prescription, determining why nursing care is needed.

Nursing systemsNursing systems

Nursing systems is conceptualized as the providers, resources, structures, methods and processes essential for the efficient and effective delivery of nursing care to aggregates of individuals.

The concentration is directed toward preparing nurse scientists with expertise in

– (1) evaluating theoretical and empirical knowledge about inter-and intra-organizational phenomena relevant to the delivery of nursing care;

– (2) developing and validating new theoretical constructs and models that explain nursing phenomena from a systems perspective.

is a unique, open systems-based perspective that provides a unifying focus for approaching a wide range of international health concerns.

Being universal in nature, it is open to creative interpretation and is widely used throughout the world as a multidisciplinary, wholistic, and comprehensive guide for excellence in nursing practice, education, research, and administration.

Betty NeumanBetty Neuman

Betty Neuman is a community health nurse and clinical psychologist who has developed this theory.

Betty M. Neuman, R.N., B.S.N., M.S., Ph.D., PLC., FAAN


The Neuman Systems Model was originally developed in 1970 at the University of California

The model was developed by Dr. Neuman as a way to teach an introductory nursing course to nursing students.

The goal of the model was to provide a wholistic overview of the physiological, psychological, sociocultural, and developmental aspects of human beings.


The model's basic central core consists of – energy resources (normal temperature range,

genetic structure, response pattern, organ strength or weakness, ego structure, and knowns or commonalities)

that are surrounded by – several lines of resistance, – the normal line of defense, and – the flexible line of defense.


The lines of resistance represent the internal factors that help the patient defend against a stressor

The normal line of defense represents the person's state of equilibrium

The flexible line of defense depicts the dynamic nature that can rapidly alter over a short period of time.

The Omaha SystemThe Omaha System

The Omaha System is a research-based, comprehensive practice and documentation standardized classification;

it can be used by multidisciplinary health care practitioners in any setting from the time of client admission to discharge.

http://www.omahasystem.org/


Consists of three relational, reliable, and valid components designed to be used together:

Problem Classification Scheme (client assessment) Intervention Scheme (service delivery) Problem Rating Scale for Outcomes (client

change/evaluation)


Is a research-based, comprehensive, standardized taxonomy. It is designed to enhance practice, documentation, and information management. It is intended for use with individuals, families, and communities who represent all ages, geographic locations, medical diagnoses, socio-economic ranges, spiritual beliefs, ethnicity, and cultural values.

Its terms are arranged from general to specific, and are intended to be easily understood by health care professionals and the general public. It provides a structure to document client needs and strengths, describe multidisciplinary practitioner interventions, and measure client outcomes in a simple and user-friendly, yet comprehensive, manner.


It enables collection, aggregation, and analysis of clinical data. It supports quality improvement, critical thinking, and communication. It fosters research involving best practices/evidence-based practice. It links clinical data to demographic, financial, administrative, and staffing data. It is a middle range theory that supports other established health care theories. Examples include Donabedian’s structure, process, and outcome approach and the Neuman Systems Model.

It is a framework for integrating and sharing clinical data that has existed in the public domain since 1975.

The Omaha SystemThe Omaha SystemProblem Classification SchemeProblem Classification Scheme

Four levels. Four domains appear at the first level and represent priority areas

of practitioner and client health-related concerns. Forty-two terms (concepts), referred to as client problems or areas

of client needs and strengths, appear at the second level. The third level consists of two sets of problem modifiers: health

promotion, potential, and actual as well as individual, family, and community.

Clusters of signs and symptoms describe actual problems at the fourth level.

The Problem Classification Scheme provides a structure, terms, and system of cues and clues to help practitioners collect, sort, document, classify, analyze, retrieve, and communicate client needs and strengths.


Environmental Domain: Material resources and physical surroundings both inside and outside the living area, neighborhood, and broader community.– Income– Sanitation– Residence– Neighborhood/workplace safety


Psychosocial Domain: Patterns of behavior, emotion, communication, relationships, and development.

The Omaha SystemThe Omaha System Intervention Scheme

It consists of three levels of professional actions or activities.

Four broad categories of interventions appear at the first level.

An alphabetical list of 75 targets or objects of action and one “other” appear at the second level.

Client-specific information generated by practitioners is at the third level.

Because the Intervention Scheme is the basis for planning and intervening, it enables practitioners to describe and communicate their practice including improving or restoring health, decreasing deterioration, or preventing illness.


CategoriesCategories: Teaching, Guidance, and Counseling: Activities designed to provide

information and materials, encourage action and responsibility for self-care and coping, and assist the individual/family/community to make decisions and solve problems.

Treatments and Procedures: Technical activities such as wound care, specimen collection, resistive exercises, and medication prescriptions that are designed to prevent, decrease, or alleviate signs and symptoms of the individual/family/community.

Case Management: Activities such as coordination, advocacy, and referral that facilitate service delivery, improve communication among health and human service providers, promote assertiveness, and guide the individual/family/community toward use of appropriate resources.

Surveillance: Activities such as detection, measurement, critical analysis, and monitoring intended to identify the individual/family/community’s status in relation to a given condition or phenomenon.

The Omaha SystemThe Omaha System Problem Rating Scale for Outcomes

The Scale consists of three five-point, Likert-type scales for measuring the entire range of severity for the concepts of knowledge, behavior, and status. Each of the sub scales is a continuum providing an evaluation framework for examining problem-specific client ratings at regular or predictable times. Suggested times include admission, specific interim points, and discharge. The ratings are a guide for the practitioner as client care is planned and provided; the ratings offer a method to monitor client progress throughout the period of service. Using the Problem Rating Scale for Outcomes with the other two schemes of the Omaha System creates a comprehensive problem-solving model for practice, education, and research.

Roy's Model Of NursingRoy's Model Of Nursing

Sister Callista Roy developed the Adaptation Model in 1976.

Definition – Roy's model of nursing sees an individual as a set of

interrelated systems, biological, psychological, and social. The individual tries to maintain a balance between each of these systems and the outside world. However, there is no absolute level of balance. According to Roy we all strive to live within a band where we can cope adequately. This band will be unique to an individual. The adaptation level is the range of adaptability within which the individual can deal effectively with new experiences.


This model comprises the four domain concepts of – person, – health, – environment, and – nursing and involves a six step nursing process.


– Roy's models sees the person as "a biopsychosocial being in constant interaction with a changing environment" (Rambo, 1984). The person is an open, adaptive system who uses coping skills to deal with stressors.

– Roy sees the environment as "all conditions, circumstances and influences that surround and affect the development and behaviour of the person" (Andrews & Roy, 1991).

– Roy describes stressors as stimuli and uses the term 'residual stimuli' to describe those stressors whose influence on the person is not clear


Roy employs a six-step nursing process which includes: – assessment of behaviour, – assessment of stimuli, – nursing diagnosis, – goal setting, – intervention and evaluation.


In the first step, the person's behaviour in each of the four modes is observed. This behaviour is then compared with norms and is deemed either adaptive or ineffective.

The second step is concerned with factors that influence behaviour. Stimuli are classified as – focal, – contextual or – residual


The nursing diagnosis is the statement of the ineffective behaviours along with the identification of the probable cause.

In the fourth step, goal setting is the focus. – Goals need to be realistic and attainable and are set in

collaboration with the person (Andrews & Roy, 1991). Intervention occurs as the fifth step, and this is when the

stimuli are manipulated. It is also called the 'doing phase' (Rambo).

In the final stage, evaluation takes place. The degree of change as evidenced by change in behaviour, is determined. Ineffective behaviours would be reassessed, and the interventions would be revised

Mandala Representing Roy’s Adaptation Model

By Noreen Frodella BSN, RN, BC, Graduate student

http://nursing.jbpub.com/sitzman/artGallery.cfm

Sister Callista Roy's Adaptation ModelSister Callista Roy's Adaptation Model

This Mandala, representing Roy’s Adaptation Model, was created to show the grouping of related/connected units which form a unified whole (environment/nature) and the adaptations that human beings undertake while living within an unpredictable natural environment. The “client/client system” is the central or focal point and is represented by the sun, the four modes of adaptation are represented by the four lightening bolts (representative of activity/energy and interaction needed to adapt), the four major concepts are represented by the clouds, the stars represent the nursing process, and the crescent moons represent the ten supporting scientific and philosophical concepts.

This Mandala utilizes symbols from nature to conceptualize Roy’s theory that focuses on human beings as an adaptive system; and as such must also adapt to the environment and the forces of nature. It reveals our continual interaction with environmental stimuli.
