Prevention of disease is the major focus of public health. One way to prevent disease is screening for disease. Disease screening can reduce morbidity and mortality as well as transmission of the disease to others. However, a lot of research and costs are associated with disease screening. Are all screening methods created equal? This week you will choose a screening method for a disease (infectious or chronic) and evaluate it. Do not repeat screening methods that another student has posted. Read Chapter 11 before posting. Discuss the following: 1) Describe the health issue in detail. Who does the health issue affect and what is the magnitude of the health issue? 2) Describe the current or proposed screening method for this disease. What is the biological basis for this screen meaning how does it detect the disease? What markers are used or what scale is used? What stage in the disease can the screen be used? Is it a mass screen or selective screening? 3) Describe the characteristics of the screen. How does it compare to the 5 attributes of a good screening test: simple, rapid, inexpensive, safe, and acceptable? 4) Evaluate the screening method. Discuss the reliability, validity, sensitivity, and specificity or the screen. Give data to support your discussion. Do not discuss Chronic kidney disease.
