Define the following groups of terms:
Primary, secondary, and tertiary prevention
Prepathogenesis and pathogenesis
How does screening for disease align with the three levels of prevention – primary, secondary and tertiary?
Define the following terms that are related to screening tests:
Reliability and validity
Sensitivity and Specificity
Predictive value (+) and predictive value (-)
What are the most appropriate applications of mass screening and selective screening? Give one example each of a mass screening test and a selective screening test.
How could screening performed in conjunction with disease surveillance contribute to the alleviation of work-related hazardous exposures?
What is meant by overdiagnosis?
Conduct a web search for “whole body scans”. They are CT scans of the entire body and are promoted as a method for early detection of abnormalities. Using your own ideas, construct a list of the advantages and disadvantages of whole body scans and reach a conclusion. To what extent are whole body scans related to the issue of overdiagnosis?
