In this lesson, we'll discuss the prevention and early detection of disease. Early detection is accomplished through screening procedures.
Upon completion of this lesson, you should be able to:
- differentiate between primary, secondary, and tertiary prevention
- calculate and differentiate between sensitivity, specificity, and positive and negative predictive values of a diagnostic test or series of tests
- recognize evidence supporting or failing to support the effectiveness of a proposed prevention measure
- identify examples of bias in screening studies.
