The goal of preventive medicine is to:

• Assess risk of individuals for disease, using techniques such as screening and health risk assessment tools.
  
• Implement interventions to modify or eliminate individuals' risk for disease/injury, using biologic, behavioral, and environmental approaches.
  
• Organize and mange practice settings to facilitate the integration and monitoring of personal preventive services and be an advocate for health promotion activities for the individual.
  
• Apply risk assessment, risk reductions, and media techniques to communities and populations including employee groups: be an advocate for health promotion and a resource for information about prevention strategies in the community.
  
• Evaluate the effectiveness of individual and community risk reduction techniques and be a consultant to physicians, industry, and government for program development and evaluation.
  
• The preventive medicine and public health share the objectives of promoting general health, preventing specific diseases, and applying the concepts and techniques of epidemiology toward these goals.
  
• Primary prevention: keeps the disease process from becoming established by eliminating causes of disease or increasing resistance to disease.
  
• Secondary prevention: interrupts the disease process before it becomes symptomatic.
  
• Tertiary prevention: limits the physical and social consequences of symptomatic disease.
