Racial/ethnic disparities in mammogram frequency among women with intellectual disability.
The purpose of this study was to collect survey and medical record data to examine associations between intellectual disability (ID) and race/ethnicity on mammogram frequency. Hispanic and Black women with ID are more likely than White women with ID to have mammograms every 2 years. Women who live in State-funded residences, are aged 50 and over, and had a mild or moderate level of ID impairment were more likely to have mammograms compared to those who lived with family or alone, were under 50, or who had severe ID impairment. The authors conclude that further research is needed to understand the mechanisms that explain these disparities.

Patient, radiologist, and examination characteristics affecting screening mammography recall rates in a large academic practice.
This retrospective study examined patient, radiologist and examination characteristics affecting screening mammography recall rates. This study used 61,198 examinations from an academic center and two outpatient centers from October 1, 2012 to May 31, 2015. Radiologists’ risk aversion, stress from uncertainty, and malpractice concerns and cancer detection rates were derived from the survey. Their annual screening volumes, clinical experience, and concentration in breast imaging was calculated. About 9.3% of screening examinations were recalled. There was no association found with radiologists’ risk aversion, stress from uncertainty, malpractice concerns and cancer detection rates and high recall rates. The most variation was found with radiologists’ annual reading volume and experience.

The effect of digital breast tomosynthesis adoption on facility-level breast cancer screening volume.
This study examined whether adoption of digital breast tomosynthesis (DBT) was associated with a decrease in screening mammography capacity across Breast Cancer Screening Consortium facilities. Facility characteristics and examination volume data were collected from facilities that adopted DBT from 2011 and 2014. The majority of facilities had no academic affiliation (73%), were nonprofit (80%) and were general radiology practices (66.7%). Monthly screening volumes were slightly higher after the adoption period but otherwise remained relatively stable before and after adoption of DBT.

Perceptions of overdetection of breast cancer among women 70 years of age and older in the USA: a mixed-methods analysis.
The authors explored older women's perceptions about the concept of overdetection of breast cancer and its influence on future screening intentions. Semistructured interviews were conducted with 59 English-speaking women aged 70 years or older with no prior history of breast cancer. The authors found that many older women did not understand the concept of overdetection, in addition to being suspicious of or resistant to the concept. Providing older women with descriptions of overdetection may not be sufficient to influence screening intentions.

Absence of an anticipated racial disparity in interval breast cancer within a large health care organization.
The researchers sought to estimate the extent of an anticipated racial disparity in interval breast cancer (IBC) within a single, large health care organization. Contrary to expectation, in patient-adjusted models, there was no IBC racial disparity. The sorting of patients by race across facilities appears to have mitigated an otherwise anticipated disparity in IBC.

Impact of a false-positive screening mammogram on subsequent screening behavior and stage at breast cancer diagnosis.
Researchers sought to examine the impact of a false positive (FP) screening mammogram on the subsequent screening mammography behavior. They found that experiencing a FP mammogram increases the risk of late stage at diagnosis compared with prior true negative (TN) mammogram Also, women with a FP mammogram were more likely to delay their subsequent screening compared with women with a TN mammogram.

Screening for breast cancer.
This case study involves a 47-year-old woman who presents to your office for a well-woman visit. She is healthy, takes no medications, and has no health concerns. She has never been diagnosed with breast cancer, nor have any of her first-degree relatives. Her digital mammography two years ago was negative, and she asks whether she should be screened again this year. The study poses three multiple choice questions together with the U.S. Preventive Services Task Force recommendations and related background information.

Transcranial doppler screening among children and adolescents with sickle cell anemia.
The study’s objectives were to assess the feasibility of using administrative claims data to identify and describe the receipt of transcranial Doppler (TCD) screening among children and adolescents with sickle cell anemia and to characterize opportunities for intervention. Despite national recommendations, TCD screening rates remain low. Successful strategies to improve TCD screening rates may capitalize on the numerous health care interactions among children and adolescents with sickle cell anemia.

Factors associated with rates of false-positive and false-negative results from digital mammography screening: an analysis of registry data.
The researchers sought to determine factors associated with false-positive and false-negative digital mammography results, additional imaging, and biopsies among a general population of women screened for breast cancer. They found that false-positive mammography results and additional imaging are common, particularly for younger women and those with risk factors, whereas biopsies occur less often. Rates of false-negative results are low.

Geographic variation in radiologist capacity and widespread implementation of lung cancer CT screening.
The researchers estimated the prevalence of capacity constraints in the radiologist workforce and resulting potential disparities in access to lung cancer screening. They found that scaling up lung cancer screening would increase imaging procedures by an average of 4% across Health Service Areas (HSAs). HSAs that were rural, with many eligible smokers, and disproportionately Hispanic or low-income smokers had significantly higher odds of facing capacity constraints.
