1.    Discussions: Role of Epidemiology in Health Care

In the course you have learned about various programs for collecting cross-sectional data for the purpose of monitoring the Nation’s health and for generating hypotheses about important illnesses. You also have learned many of the important principles and techniques used in epidemiology to test various hypotheses about the relationship between specific exposures and outcomes. In addition, you have learned some techniques for evaluating scientific articles to assess the strengths of studies you might read. All of these skills are used in health care on a daily basis.
Think about how what you have learned about epidemiology, relates to the work you want to do in health care in the future. For this week’s discussion, post a summary of two situations you anticipate might happen in your future work and describe how you might use the tools of epidemiology you have learned to help in those situations.

2.    Reflection: Part 1 Medical Record vs. Claims Data

Health care today has an emphasis on providers switching from paper medical records to Electronic Health Records (EHR). This means that increasingly a patient’s health care information is computerized. For years, computer has done the financial transactions associated with health care. The financial data is submitted to insurance companies and the government using an official coding system (DRGs and CPT codes). What do you think the difference might between the information contained in a patient’s Electronic Health Record and the insurance claim record in terms of its usefulness for epidemiologic studies?

Part 2 Medical Record vs. Claims Data
Based on the course materials you have learned that electronic data is very useful in conducting retrospective studies. The information is easy to access with the correct patient consent and much less expensive than collecting information directly from the patients prospectively.
To use electronic data you have to have a plan for how you will pull the patient records you are interested in out of the large number of patient records in the data system. Then you have to subset your sample into your test and control groups.
Briefly describe how you would pull and subset retrospective electronic data to conduct a) a case control study, and b) a cohort study.

3.    Reflection: Part 1 Policies in Epidemiology
Read back through all of your Reflections. Describe what you believe are the 2 most important things you learned from the course.

Part 2 Policies in Epidemiology

Think about everything you have learned in the course.What is your current understanding of what the science of epidemiologic studies? What role do you see the material from this course playing in your future career plans?

Discussion
Epidemiology studies are very critical in health care since they are concerned with studying diseases in certain populations. According to Last (2001), causes and patterns related to these diseases are established and counter measures are set in place to cumber these diseases. In my future work, I anticipate an outbreak of a new disease since new strains of diseases are popping up and the need to counter them is mandatory. Tools in epidemiology may prove to be very useful in finding the cause and reducing the spread of the disease. Collecting and analyzing data in order to establish the cause factors of the disease and establishing the various risk factors that are associated with the disease will be critical in cumbering the disease. Necessary steps will be taken to ensure that the population is made aware of the cause of the disease and what risk factors to avoid in order to ensure a healthy status and therefore saving many lives in the process.
Last (2001) explains that another situation requiring tools...
