    Collapse Overview
    Dr. Nguyen’s research is focused on understanding and optimizing hospital care in safety-net settings and developing pragmatic approaches to addressing social determinants of health, particularly on the development and evaluation of transitional care strategies that address social vulnerabilities among individuals with complex medical needs.

    Her current work, funded through the National Heart, Lung, and Blood Institute, seeks to develop strategies to predict, understand, and address coexisting social vulnerabilities among adults hospitalized with congestive heart failure or ischemic heart disease at high risk for readmission.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
