Agenda for the Unit 7 Seminar

Unit 7 Learning Objectives

Discussion of the Importance of the Efficacy of Screening

Unit 7 Discussion Questions

Unit 7 Learning Objectives

Recognize the effects of  geography on health outcomes. 

Recognize the power politics holds on distribution of health resources which in turn affects health outcomes.

Describe geo-political design components. Evaluate the impact of eHealth and the use of

advanced technology related to geography on health and wellness models.

Identify design components for incorporation into a geo-political model of health and wellness.

A Closer Look at Breast Cancer Screening . . . . Why? Recognize the power politics holds on

distribution of health resources which in turn affects health outcomes (Unit 7 Learning Outcome)

What is the Issue?

2002 Recommendations:- A “B” Recommendation for screening mammography

for women 40 years or older.

2009 Recommendations:- A “C” Recommendation for screening mammography

for women 40 years or older.

U.S. Preventive Services Task Force

U.S. Preventive Services Task Force

“The mission of the USPSTF is to evaluate the benefits of individual services based on age, gender, and risk factors for disease; make recommendations about which preventive services should be incorporated routinely into primary medical care and for which populations; and identify a research agenda for clinical preventive care.”

“Public Law Section 915 mandates that AHRQ convene the USPSTF to conduct scientific evidence reviews of a broad array of clinical preventive services, develop recommendations for the health care community, and provide ongoing administrative, research, technical, and dissemination support.”

Why the Change?

“The precise age at which the benefits from screening mammography justify the potential harms is a subjective judgment and should take into account patient preferences.”

Benefits vs. Risks Beneficence, Non-Malfeasance

Reduced chance of dying vs. false positives, unnecessary biopsies

“With its new recommendations, the USPSTF is essentially telling women that mammography at age 40 to 49 saves lives; just not enough of them. The task force says screening women in their 40s would reduce their risk of death from breast cancer by 15 percent, just as it does for women in their 50s. But because women in their 40s are at lower risk of the disease than women 50 and above, the USPSTF says the actual number of lives saved is not enough to recommend widespread screening. The most recent data show us that approximately 17 percent of breast cancer deaths occurred in women who were diagnosed in their 40s, and 22 percent occurred in women diagnosed in their 50s. Breast cancer is a serious health problem facing adult women, and mammography is part of our solution beginning at age 40 for average risk women.”

Efficacy of a Screen?

Validity – Is the test accurate?

Reliability – Will the test produce the same result when repeated?

Validity of a Screen

Sensitivity – false negatives - the extent to which those with the disease will be told they don’t have the disease.

Specificity – false positives – the extent to which those without the disease will be told they do have the disease.
