Modes of Intervention
Modes of intervention represent the specific actions taken at different levels of prevention to interrupt the natural history of disease.
Key Categories
| Mode | Action |
|---|---|
| Health Promotion | Education, lifestyle changes, and environmental modification. |
| Specific Protection | Immunization, chemoprophylaxis, and personal protective equipment (PPE). |
| Early Diagnosis & Treatment | Screening, case finding, and timely pharmacological/surgical intervention. |
| Disability Limitation | Preventing complications or further progression of an existing disease. |
| Rehabilitation | Restoring physical, psychological, and social functioning. |
High-Yield Clinical Notes:
- Proactive vs. Reactive: Health promotion and specific protection act *before* disease exists; the latter modes are applied *after* the disease process has begun.
- Integration: Effective public health programs often combine multiple modes simultaneously (e.g., screening for hypertension combined with dietary education).
- Application: Memorizing these modes is essential for understanding how to structure public health interventions for USMLE and NEET PG.
