Epidemiology Case Control Study Design Doctoral Dissertation Definition
In this module, you will learn the key elements of case-control study design, and you will learn how to estimate the appropriate measure of association when presented with data from a case-control study.
Cohorts were ancient Roman military units, but in modern epidemiology the word “cohort” is used to describe a group with a shared characteristic.
Studies can be time- and resource-intensive, and a hastily constructed study might not answer the correct questions.
For example, in a foodborne disease outbreak investigation, if the culprit food is not on your study’s questionnaire, you probably will not be able to implicate it.
In this module, you will be introduced to these common characteristics, and you will learn the main principles of ecological and cross-sectional studies, as well as when it is appropriate to use them.
By the end of the module, you will be able to identify and critically consider the advantages and disadvantages of these study designs.
-specific questionnaire with approximately 40 common food sources of listeriosis (e.g., soft cheese and deli meat).Imperial students benefit from a world-leading, inclusive educational experience, rooted in the College’s world-leading research.Our online courses are designed to promote interactivity, learning and the development of core skills, through the use of cutting-edge digital technology.You will also develop the skills to identify strengths and limitations of the various study designs.By the end of this course, you will be able to choose the most suitable study design considering the research question, the available time, and resources.The range of different study designs can be quite confusing.However, to help you navigate the maze of study designs, we can split them into groups which share common characteristics.Analytic studies typically should be used to test hypotheses, not generate them.However, in certain situations, collecting data quickly about patients and a comparison group can be a way to explore multiple hypotheses.This module focuses on case-control studies, which is one of the best known epidemiological study designs.Case-control studies are particularly useful when you don’t have the luxury of waiting for a long follow-up period to conclude.
