Screening for Disease
Although many individuals and organizations may endorse the goal of screening programs, the details and implementation are often controversial. For some types of screening, it can be quite challenging to weigh the human and economic costs and benefits and determine a clear recommendation. For instance, in an article in the New England Journal of Medicine, Dr. Michael Barry (2009) indicates that “serial PSA [prostate-specific–antigen] screening has at best a modest effect on prostate-cancer mortality during the first decade of follow-up. This benefit comes at the cost of substantial over-diagnosis and overtreatment. It is important to remember that the key question is not whether PSA screening is effective but whether it does more good than harm.”
This week’s Learning Resources include articles about screening programs for four different diseases that contain potentially controversial recommendations. For this Discussion, you will select a disease and examine the epidemiological evidence to assess a recommendation for screening guidelines. In addition, you will consider possibilities for furthering policy to promote population health related to this disease.
To prepare:
By tomorrow 04/17/2018 3pm, write a minimum of 550 words in APA format with at least 3 scholarly references from the list of required readings below. Include the level one headings as numbered below:
Post a cohesive scholarly response that addresses the following:
1) Summarize the recommendations of your selected article. Discuss ethical considerations and whether or not you believe the recommendations are justified.
2) Describe the epidemiological evidence in support of your position.
3) Identify whether the screening program you review is population-based or high-risk based and how that influences your assessment.
4) How can the reported data be used to move policy forward for improving population health around this issue?

Chapter 10, “Data Interpretation Issues”
Chapter 11, “Screening for Disease in the Community”
Chapter 11 examines aspects of screening for disease, including characteristics of a good screening test and how screening programs can be evaluated.

Chapter 13, “Decision Support”
This chapter addresses measurement and analysis tools used to support decision making for improvement, accountability, and research related to population health. The three main purposes of measurement in population health (improvement, accountability, research) provide the framework for this chapter.
Note: You will need to review the following four articles to complete this week’s Discussion: (See attached file for the articles)
U.S. Preventive Services Task Force. (2009). Screening for breast cancer. Retrieved from http://www.uspreventiveservicestaskforce.org/uspstf/uspsbrca.htm (See attached File).
This is a summary of the controversial USPSTF proposal regarding screening for breast cancer using mammography and breast self-examination. It includes the recommendations, rationale, and evidence supporting the proposal.

Retrieved from http://www.biomedcentral.com/1471-2334/11/3 (See attached File).
This article examines tuberculosis screening practices among migrants from high-incidence countries to low-incidence countries. Consider the benefits and challenges of standardizing screening requirements at the global level.
Creighton, P., Lew, J.-B., Clements, M., Smith, M., Howard, K., Dyer, S., Lord, S., & Canfell, K. (2010). Cervical cancer screening in Australia: Modelled evaluation of the impact of changing the recommended interval from two to three years. BMC Public Health, 10, 734–747 (See attached File).
This article examines the cost benefits and health consequences of screening for cervical cancer every 3 years as opposed to every 2 years. Researchers summarize other studies that support this change as well.
Hugosson, J., Carlsson, S., Aus, G., Bergdahl, S., Khatami, A., Lodding, P., & … Lilja, H. (2010). Mortality results from the Göteborg randomised population-based prostate-cancer screening trial. Lancet Oncology, 11(8), 725–732 (See attached File).
Prostate cancer screening can result in the detection of other cancers that may “never present during the patient’s lifetime (over-diagnosis) and it results in unnecessary treatments that can damage men’s quality of life (over-treatment).” However, this research study also demonstrates how prostate cancer screening also can reduces mortality rates in some instances.
