Regionally, our toxicology attendings work with the teaching faculty at the New York City Poison Control Center and collaborate on educational programs and research with the NYCPCC fellows-in-training and other faculty. All members of our toxicology faculty have contributed to medical student, nursing, APP and resident education, peer review publications, textbook chapters, as well as regional, national and international lectures on toxicology. In addition to direct patient care, the medical toxicology service is helping to enhance medication safety throughout the institution.
