Description of Clinical Expertise
Dr. Kohn's clinical interests include pulmonology and critical care. She serves as an attending physician on the following services: Pulmonology Primary and Consult Services, Pulmonary Diagnostic Lab, Medical Intensive Care Unit, Long-Term Acute Care Hospital, and Critical Care Outreach and Procedure Service of the Hospital of the University of Pennsylvania.Description of Research Expertise
Dr. Kohn completed a Master of Science in Clinical Epidemiology at the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania. Her research interests lie at the intersection of health services research and healthcare operations within learning health systems. Her primary research interests include "ward capacity strain," when the demand for clinical resources on hospital wards exceeds availability thus impacting patient care, and "geographic dispersion," when specialty wards exceed capacity and patients overflow to alternate locations. Her goals include improving patient-centered outcomes and healthcare efficiency within learning health systems.Selected Publications
