Impact of Perceived Discrimination and Pandemic Attitudes on Cancer Screening Behaviors Among Asian American Women: A Sequential Explanatory Mixed-Methods Study.
J Am Coll Radiol
December 2024
Vice Chair for Radiology, Department of Radiology, Massachusetts General Hospital, Boston, Massachusetts; Co-Chair, RSNA Health Equity Committee; Associate Editor, Journal of the American College of Radiology.
Purpose: The aim of this study was to assess how pandemic-related health concerns and discrimination affected cancer screenings among Asian American women (AAW).
Methods: A two-phase explanatory mixed-methods study was conducted. In phase 1, a survey was distributed among AAW eligible for lung, breast, or colorectal cancer screening to assess delays during the pandemic, concerns about contracting coronavirus disease 2019 (COVID-19), barriers to care, and experiences of discrimination.

Director of Economic and Health Services Research, The Harvey L. Neiman Health Policy Institute, Reston, Virginia.
Objective: The Neiman Imaging Comorbidity Index (NICI) was developed and validated in a claims dataset encompassing >10 million privately insured beneficiaries, in which it outperformed the commonly used Charlson Comorbidity Index (CCI) in predicting advanced imaging use. This external validation assessed the broader generalizability of NICI for predicting receipt of advanced imaging in nationally representative populations, including patients insured by Medicare, Medicaid, and private payers.
Methods: All 2018 to 2019 patient-level claims from the CMS Medicare 5% Research Identifiable File, CMS Medicaid 100% Research Identifiable File, and private insurance (commercial and Medicare Advantage) claims from Inovalon Insights, LLC, were included.
State-Level Medicaid Reimbursement and Imaging Utilization by Medicaid and Children's Health Insurance Program Patients.
J Am Coll Radiol
November 2024
Executive Director, Harvey L. Neiman Health Policy Institute, Reston, Virginia.
Purpose: To determine if relative Medicaid-to-Medicare reimbursement rates are associated with patient imaging utilization.
Methods: This cross-sectional study estimated the association of diagnostic imaging utilization with the state-level Medicaid-to-Medicare reimbursement ratio (MMRR) of professional payments. State-specific reimbursement ratios were computed for each imaging modality.
National Utilization Trends of Inpatient Procedures for Symptomatic Uterine Fibroids and Adenomyosis: A 10-Year Analysis.
J Am Coll Radiol
December 2024
Assistant Professor, Interventional Radiology Residency Program Director, Division of Vascular and Interventional Radiology, Department of Radiology, University of North Carolina School of Medicine, Chapel Hill, North Carolina.
Purpose: The aim of this study was to determine changes in procedural utilization for symptomatic uterine fibroids and adenomyosis from 2011 to 2020.
Methods: An institutional review board-exempt retrospective study of the National Inpatient Sample database from 2011 to 2020 was performed using International Classification of Diseases, Ninth Revision, and International Classification of Diseases, 10th Revision, diagnosis and procedural codes for uterine fibroids, adenomyosis, hysterectomy, myomectomy, uterine artery embolization (UAE), and endometrial ablation. Patients with endometriosis, uterine cancer, placenta accreta spectrum, pelvic inflammatory disease, and uterine prolapse were excluded.

Harvard Medical School, Boston, MA; Center for Evidence-Based Imaging, Department of Radiology, Brigham and Women's Hospital, Boston, MA. Electronic address:
Objective: To determine whether point-of-order clinical decision support (CDS) based on the Wells Criteria improves CT pulmonary angiogram (CTPA) yield and utilization in hospitalized patients in an enterprise-wide health system and identify yield-related factors.
Methods: This retrospective IRB-approved cross-sectional study in an urban, multi-institution health system included hospitalized patients undergoing CTPA 12 months before and after CDS implementation (entire cohort). Chi-square test was used to compare PE yield in patients in whom providers overrode vs.
