The library doesn't contain dedicated content on Orem's nursing theory. I'll answer from my knowledge.
Orem's Self-Care Deficit Nursing Theory (SCDNT)
Dorothea Orem (1914–2007) developed one of the most widely used nursing theories. It focuses on the individual's ability to perform self-care and the nurse's role when that ability is compromised.
Three Interrelated Theories
The SCDNT is actually a general theory composed of three sub-theories:
1. Theory of Self-Care
- Self-care is the practice of activities that individuals perform on their own behalf to maintain life, health, and well-being.
- Self-care agency refers to the learned ability to carry out self-care.
- Therapeutic self-care demand is the totality of self-care actions required at a given time to meet self-care requisites.
Self-Care Requisites are grouped into three categories:
| Category | Description | Examples |
|---|---|---|
| Universal | Common to all humans across the lifespan | Air, water, food, elimination, activity/rest, solitude/social interaction, hazard prevention, normalcy |
| Developmental | Related to life stages or events affecting development | Pregnancy, aging, loss of a loved one |
| Health deviation | Arise from illness, injury, or disease | Seeking medical care, following treatment regimens, managing side effects |
2. Theory of Self-Care Deficit
- The core of the overall theory.
- A self-care deficit exists when a person's therapeutic self-care demand exceeds their self-care agency (i.e., they cannot meet their own needs).
- This is the legitimizing criterion for nursing care — nursing is needed when and only when a self-care deficit exists or is anticipated.
3. Theory of Nursing Systems
Describes how nursing care is organized based on the degree of the patient's self-care deficit. Orem identified three nursing systems:
| System | Who performs care | When used |
|---|---|---|
| Wholly Compensatory | Nurse performs all self-care | Patient has no ability to act (e.g., coma, anesthesia) |
| Partly Compensatory | Nurse and patient share care | Patient can do some but not all actions (e.g., post-op recovery) |
| Supportive-Educative | Patient performs care; nurse guides | Patient can learn but needs support or instruction (e.g., diabetic teaching) |
Five Methods of Helping (Nursing Actions)
Orem described five ways a nurse can assist:
- Acting for or doing for another
- Guiding another
- Supporting another (physically or psychologically)
- Providing a developmental environment
- Teaching another
Key Concepts Summary
| Concept | Meaning |
|---|---|
| Self-care | Deliberate actions to maintain health |
| Self-care agency | Capacity/ability to perform self-care |
| Self-care deficit | When demand exceeds agency |
| Nursing agency | Nurse's capacity to know and help |
| Therapeutic self-care demand | Total actions needed to meet requisites |
Clinical Application
- A diabetic patient newly diagnosed who needs insulin education → Supportive-Educative system
- A post-surgical patient who can ambulate but cannot change dressings → Partly Compensatory system
- A patient on mechanical ventilation in the ICU → Wholly Compensatory system
Significance
Orem's theory is foundational in nursing education and practice. It:
- Provides a framework for patient assessment (identify self-care deficits)
- Guides care planning (match nursing system to patient need)
- Promotes patient autonomy and independence as a goal
- Is widely applied in chronic disease management, rehabilitation, and community health nursing
