Which objective describes evaluating both existing and new preventative and therapeutic measures and modes of health care delivery?

• A. To identify the etiology and risk factors
• B. To study the natural history and prognosis
• C. To evaluate measures and modes of health care delivery
• D. To provide the foundation for developing public policy

Answer: (C)

Evaluating how well preventive and therapeutic measures work and how health care is delivered focuses on assessing the effectiveness of interventions in real-world settings and how services are organized, accessed, and used. This objective looks at both existing programs and potential new ones, measuring outcomes, costs, and equity to determine what should be continued, modified, or adopted. By studying who benefits, how they access care, and the overall impact on health, it informs improvements in both clinical practice and delivery systems. The other goals center on finding causes of disease, describing how diseases progress without intervention, or shaping policy rather than directly evaluating intervention effectiveness and delivery methods.
