    Dr. Blumenthal performs epidemiology, informatics, outcomes and cost-effectiveness research in the field of drug allergy.  Her past research evaluated both true drug hypersensitivity and the clinical impact of over-reported drug allergies on patients and healthcare systems, and includes over 50 peer-reviewed manuscripts. As part of her post-doctoral research, she designed, implemented and evaluated a hospital-wide guideline for antibiotic prescribing for patients with a reported β-lactam antibiotic allergy at  Mass General.  After successfully demonstrating the guideline’s safety, feasibility, and positive impact on antibiotic stewardship at two institutions,  she led the implementation of this guideline throughout Mass General Brigham hospitals.
