Primary Care Providers Underutilize Breast Screening MRI for High-Risk Women

ObjectiveSupplemental MRI screening for women at high risk for breast cancer is underutilized. Our study assessed how primary care providers in our healthcare network identify high-risk women and recommend high-risk screening breast MRI.MethodsAn electronic survey was distributed to providers in OB/GYN, family, and internal medicine departments between 1/14/19 and 3/22/19. The survey inquired about methods used to assess breast cancer risk, familiarity with the American Cancer Society's definition of high-risk, and whether screening breast MRI is recommended for high-risk women.ResultsResponse rate was 17% (89/524). After excluding providers who ordered ≤10 mammograms per year, the study included 75 respondents, who mostly ordered 10-1000 mammograms per year and supported annual/biennial screening mammogram starting at age 40-50 years. More providers reported estimating breast cancer risk qualitatively (with family, clinical history, and/or breast density) than quantitatively with risk calculators (73/75, 97% vs 22/75, 29%). A minority of providers (23/75, 31%) correctly defined high lifetime risk. Only 9/75 (12%) providers recommended screening MRI for high-risk women. Use of quantitative risk calculators or ability to correctly define high-risk were not associated with likelihood of recommending MRI screening. More providers had recommended MRI for screening in the setting of dense breasts than for high-risk screening (23/75, 31% vs 9/75, 12%).ConclusionPrimary care providers at our institution did not routinely recommend screening MRI for high-risk women. Risk assessment and reporting at the time of mammography may improve MRI utilization and is an opportunity for radiologists to add value and directly participate in patient-centered care.     

Respiratory protection for Health Care Workers

Chemical, Biological, Radiological and Nuclear incidents are rare, but the likelihood of any medical facility having to deal with contaminated or contagious casualties is not, Health Care Workers (HCW) often being exposed to infectious or toxic substances. Although medical staff routinely take measures to protect themselves against exposure to infection by wearing protective clothing, they rarely consider the inhalational route as a threat. This paper presents a series of cases where HCW's have been exposed to toxic or infectious material through the respiratory route, discusses standards of respiratory protection and describes how this risk can be mitigated to protect medical personnel.     

Strategies for Dose Optimization: Views From Health Care Systems

BackgroundAdvances in CT have facilitated widespread use of medical imaging while increasing patient lifetime exposure to ionizing radiation.PurposeTo describe dose optimization strategies used by health care organizations to optimize radiation dose and image quality.Materials and methodsA qualitative study of semistructured interviews conducted with 26 leaders from 19 health care systems in the United States, Europe, and Japan. Interviews focused on strategies that were used to optimize radiation dose at the organizational level. A directed content analysis approach was used in data analysis.ResultsAnalysis identified seven organizational strategies used by these leaders for optimizing CT dose: (1) engaging radiologists and technologists, (2) establishing a CT dose committee, (3) managing organizational change, (4) providing leadership and support, (5) monitoring and benchmarking, (6) modifying CT protocols, and (7) changes in equipment and work rules.ConclusionsLeaders in these health systems engaged in specific strategies to optimize CT dose within their organizations. The strategies address challenges health systems encounter in optimizing CT dose at the organizational level and offer an evolving framework for consideration in dose optimization efforts for enhancing safety and use of medical imaging.

The Impact of Nonphysician Providers on Diagnostic and Interventional Radiology Practices: Regulatory,Billing, and Compliance Perspectives

The numbers of nurse practitioners and physician assistants are increasing throughout the entire health care enterprise, and a similar expansion continues within radiology. Some practices have instead embraced radiologist assistants. The increased volume of services rendered by this growing nonphysician provider subset of the health care workforce within and outside of radiology departments warrants closer review. The authors evaluate the recent literature and offer recommendations to radiology practices regarding both regulatory and scope-of-practice issues related to these professionals. Additionally, billing and compliance issues for care provided by nurse practitioners, physician assistants, and radiologist assistants are detailed. An analysis of the integration of these professionals into interventional and diagnostic radiology practices, as well as potential implications for medical education, is provided in the second part of this series.
