  1. Organizing Frameworks applied to Community Health Nursing

  2. Community Assessment and Nursing Diagnosis, Data Collection, Analysis and Synthesis

  3. By the end of this lecture you will be able to: • explain what is meant by a theory and a model of nursing • understand the main features of at least two models of nursing • understand how to critically review a model • Identify how the application of models to practice influences the activity of the nurse and the experience for the patient or client

  4. Additional References…………. • Models of nursing practice. McGee P. Stanley Thornes 1998 • Conceptual bases of professional nursing. Leddy S. Pepper J. Lippincott 4th ed.. 1998 • Foundations of nursing practice. Hogston R & Simpson P. Macmillan 1999 (Ch 14)

  5. Nature of theory:“represent a scientist’s best effort to describe and explain phenomena”Pollitt & Hungler 1997

  6. Theory…… “…is a general statement that summarizes and organizes knowledge by proposing a general relationship between events - if it is a good one it will cover a large number of events and predict events that have not yet occurred or been observed”Robson C.

  7. “an internally consistent group of relational statements (concepts, definitions & propositions) that present a systematic view about phenomenon and that is useful for description, explanation, prediction and control. A theory ….is the primary means of meeting the goals of the nursing profession concerned with a clearly defined body of knowledge”Walker & Avant 1996 (cited by Jasper M in Hogston & Simpson))

  8. Purpose of theory • Support the development of knowledge through thesis and contestability • Explains and predicts outcomes • Supports decision making • Embeds goals and outcomes for the client and by implication for the nurse • Supports modeling of processes of nursing

  9. Classifying theories • Meta-theory (Theory building - values etc) • Grand theory (Broad conceptual frameworks - not testable e.g. Leininger theory of transcultural care) • Middle range theory (Narrower and testable e.g. Peplau) • Practice Theory (situational theory - focuses on the way in which nursing is practised e.g. Norton’s theory of nursing elderly people)

  10. Typology: • Descriptive theory: Explains through describing relationships and patterns within the framework (e.g. Roper et al) • Predictive Theories: Address the consequences of interventions (e.g. Noddings theory of care)

  11. The medical model • Bio-reductionist • Differential diagnosis: signs & symptoms • Provision of treatment • Scientific theory - testable and not contestable • Goals - cure and therapy • Evaluation of treatment efficacy

  12. Nursing models • Located in social science • Constructed • Contestable knowledge • Capable of change and development • Embed values and culture

  13. What sort of theories would you use? • Tony Archer (18 years) underwent surgery to have a below knee amputation of his left leg • Peggy Mountford is 82 years old, lives alone with no family and is becoming increasingly confused and depressed

  14. What sort of theories did you identify? • Physiology • Psychology • Sociological theory • Nursing theories • Descriptive theory • Predictive theory

  15. Metaparadigm: constructs in all nursing theories • The person • the environment • health • nursing

  16. Commonly used models • Roper, Logan & Tierney (ADL) • Peplau (interpersonal communication) • Orem (Self-Care) • Roy (adaptation model) • Wolfensberger (social role valorisation) • Carper (personal explanations)

  17. Roper, Logan & Tierney • Developmental model - emphasises growth & development • Person oriented • Focus on change • Sees process over time • Sees a range of activities of daily living changing with maturation • Supporting and enabling • Draws on Henderson’s work strongly

  18. Callister Roy’s model • Systems model - person is made up of systems • Systems interact with the environment • Health is equilibrium and managed systems • Nursing is supporting adaptation to environment • Is holist, purposeful and unifying • Adaptive modes: physiologic, self concept, role function, interdependence • Health is a process of responding positively to environmental changes

  19. Model and Nursing Model • A conceptual model • A nursing model is a representation of nursing, not a reality. • A nursing model is an abstract of reality from the nursing perspective.

  20. The purpose of nursing model (1) • Provide a map for the nursing process *Guide assessment (What do you assess?) *Guides analysis *Dictates nursing diagnoses *Assists in planning *Facilitates evaluation

  21. The purpose of nursing model (2) • Provide a curriculum outline for education • Represents a framework for research • Provides a basis for development of theory • A model not only describe what is but also provides a framework for making decisions about what would be.

  22. Community-as-partner model • Neuman’s model of a total-person approach • Community-as-client model: public health and nursing • Community-as-partner model: primary health care with two central factors • The first factor the focus on the community as partner represented by the community assessment wheel at the top. • The second factor is the use of nursing process.

  23. The core of assessment • People who make up the community *Demographic data *Values, beliefs, and history

  24. Lines of defense • Normal line of defense: level of health of a community • Eight subsystems • Flexible line of defense: a buffer zone of a community

  25. The selection of eight subsystem • Examining the selection of subsystems that have been identified. Can you think of any that have been omitted?

  26. Line of resistance • Line of resistance: community’s strength • Stressors: tension-producing stimuli • The degree of reaction: the amount of disequilibrium or disruption that results from stressors impinging on the community’s lines of defense.

  27. Analyze data • Compare and contrast your data with the neighbor areas and the national data. • Compare and contrast your data for 3 to 5 years. • Interpret your data

  28. Nursing diagnosis • Stressors and degree of reaction become part of the community nursing/health diagnosis (health problem). • Example: the increased rate of respiratory illness (a degree of reaction) related to air pollution (a stressor)

  29. Stressors leading to?? • The outcome of a stressor impinging on a community is not always negative. Can you think of an example that stressors may lead to positive outcomes?

  30. Community health diagnosis (1) • Comparing nursing diagnosis and community health diagnosis (see handout) • Community health diagnosis is preferred over community nursing diagnosis

  31. Community health diagnosis (2) • The community health diagnosis gives direction to both nursing goals and its interventions. • The goal is derived from the stressors • The goal may include * the elimination or alleviation of the stressor * strengthening of the community’s resistance through strengthening the lines of defense.

  32. Community health diagnosis (3) • The goal should state the degree of reaction

  33. Intervention • Three modes of prevention: primary prevention, secondary prevention, and tertiary prevention

  34. Primary vs. tertiary prevention • In the case of 921 earthquake will you give an example of primary vs. tertiary prevention?

  35. Evaluation • Feedback from the community

  36. Final note • Health may not be a primary goal of the community, It is, however, an important resource for the community to meet its goals. • The consequences intended in this model include a strengthened normal line of defense, increased resistance to stressors, and a diminished degree of reaction to stressors by the community.
