This research paper includes a review of the application of the tools of epidemiology to healthcare policy. Epidemiology entails studying the distribution and determinants of health-related states or events. The role of epidemiology in public health is its application in controlling health problems. Through epidemiology, researchers can identify the root cause and risk factors surrounding a disease. Epidemiology also aids in determining the extent of a disease in a specified population. Knowing the natural history and sources of illness serve as part of the importance of epidemiology in clinical practice. This way, it is possible to evaluate both existing and new preventive and therapeutic measures and modes of health care delivery. Therefore, epidemiology will provide the foundation for developing public policy and making regulatory decisions relating to environmental problems.

THE ROLE OF EPIDEMIOLOGY IN EVIDENCE-BASED POLICY MAKING
Evidence-based policymaking is significant importance of epidemiology in clinical practice. We can base sound public health policy on relevant and timely information from epidemiology studies. The data collected reflects evidence from various sources as well as individual policies and programs. Tools of epidemiology guide systematic and objective assessments of the science to formulate evidence-based policies. Additionally, the assessments include meta-analyses, decision analyses, and economic evaluations. The theoretical and qualitative methods of the social sciences enrich and broaden scientific knowledge. This serves to show the significant role of epidemiology in public health. Lastly, it increases recognition of the importance of context and generates frameworks and questions suitable for quantitative studies and analyses.

APPLICATION OF EPIDEMIOLOGY AND EPIDEMIOLOGY IN PUBLIC HEALTH PRACTICE
Many scientists consider the role of epidemiology in public health as the fundamental science underpinning of public health practice. Information form epidemiology studies is vital to form organized community efforts aimed at the prevention of disease. In using the tools of epidemiology, we can promote health by following several epidemiologic steps in the public health cycle. We must conduct a needs assessment, set priorities, formulate objectives, and construct logic models. These steps guide the achievement of the importance of epidemiology in clinical practice. After that, we must develop evaluation plans, perform quality control, and analyze processes and outcomes. Therefore, we can attain evidence-based policies from the application of epidemiology.
