Overview
Ammar Sarwar MD is an Assistant Professor of Radiology at Harvard Medical School and an interventional radiologist at Beth Israel Deaconess Medical Center in Boston. He performs all types of vascular and non-vascular minimally invasive procedures with a focus on interventional oncology and hepatobiliary interventions. Dr. Sarwar is a health services researcher investigating the intersection of costs and outcomes for diagnostic imaging and image-guided procedures in healthcare delivery. His current focus includes time-driven activity based costing for interventional radiology procedures, investigating access to interventional radiology services in the United States, and causes for variations in 30 day readmissions and mortality after interventional radiology procedures in the United States. Nationally, Dr. Sarwar serves as an alternate advisor to the American Medical Association's CPT editorial committee, as a member of the Center of Medicare and Medicaid Services (CMS) Medicare Evidence Development and Coverage Advisory Committee, and as a member of CMS MACRA Clinical Care Committee focusing on cost measurement.

Publications listed below are automatically derived from MEDLINE/PubMed and other sources, which might result in incorrect or missing publications. Faculty can login to make corrections and additions.
Newest   |   Oldest   |   Most Cited   |   Most Discussed   |   Timeline   |   Field Summary   |   Plain Text
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.
