Fellowship in Medical Toxicology


Introduction
Welcome to the Medical Toxicology Fellowship, sponsored by the
Department of Emergency Medicine, New Jersey Medical School in conjunction with, and housed within, the New Jersey Poison Information and Education System (NJPIES). We are a dynamic and growing program, founded in 2019, and are excited to share what we think makes medical toxicology training in Newark a fantastic experience.

 

NJPIES is the statewide poison center, serving a population of 9 million, with over 50,000 poison-related calls annually from the public and healthcare providers. Our medical toxicology division, staffed by a diverse and accomplished toxicology faculty, and our dedicated fellows, provides medical consultation to both the poison center as well as our active hospital-based toxicology consultation service.

 

We are a fully accredited two-year program through the ACGMEs Review Committee for Emergency Medicine. We accept physicians board-eligible or board-certified in a primary specialty. Candidates must meet the requirements to obtain a license to practice medicine in New Jersey and meet the requirements to obtain a U.S. Drug Enforcement Administration registration before beginning the fellowship. Completion of an ACGME-certified medical toxicology fellowship is required to sit for the Medical Toxicology Certification examination.

 

In addition to the categorical Medical Toxicology fellowship, we are proud to offer the only combined Addiction Medicine and Medical Toxicology fellowship at Rutgers University New Jersey Medical School in the nation. Over the span of two-and-a-half years, the program provides Fellows with a solid foundation in addiction medicine and toxicology, while fostering a multidisciplinary approach to patient care. Taught by a diverse and nationally recognized faculty in both specialties, the synergistic nature of these disciplines allows Fellows to acquire more comprehensive skills and a broader perspective on the overlapping aspects of addiction and toxicology. They will develop critical thinking skills, enhance their ability to identify and manage patients with complex toxicologic, compassionately treat patients with substance use disorders, and provide evidence-based interventions to prevent and treat drug-related toxicities. Furthermore, the program promotes collaboration and communication between Addiction Medicine and Medical Toxicology, resulting in more effective patient care and improved outcomes.

 

Both fellowships are currently accepting applications for the academic year beginning July 2025. Applications and supporting materials can be submitted through the Electronic Residency Application Service (ERAS). Our program identifier is 1183311002. For more information on dates and deadlines for the 2024-25 fellowship application season, please see the ERAS 2025 Fellowship Application Timeline. We participate in the National Resident Matching Program (The Match”).

Objectives of the Fellowship

-   Learn and incorporate the knowledge and skills necessary to provide excellent bedside and telemedicine care to patients with a range of toxicologic issues.

-   Acquire in-depth understanding of the core content of medical toxicology, including the diagnosis and management of poisoned patients, substance use and withdrawal, occupational and industrial exposures, environmental toxicology and toxinology, laboratory science, public health, and more.

-   Develop facility in acquiring, critically evaluating, and incorporating current and past literature that supports our practice, with an emphasis on understanding the controversies and competing views.

Fellowship Education and Curriculum
Fellowship is an incredible learning experience, with a vast amount of information to absorb. So much learning is derived through the interaction of clinical cases with bedside care. This is supported through discussion, reading, supplemental materials, and follow up. A formal educational
curriculum, combined with the knowledge and teaching of the faculty and CSPIs, as well as the diversity of cases that come through NJPIES, rounds out the educational experience.

 

-   Fellows rounds and case review - daily, mediated by faculty and fellows

-   Didactic rotator rounds - daily, coordinated between fellows, faculty, and ATEAM (see below)

-   Core content - regular reading assignments from the Core Content of Medical Toxicology, with fellow generated question bank / flashcards, which complements our board review efforts

-   Structure of the Week, Toxicology History of the Month

-   Metal Monday", Occ Tox Tuesday”, Pharmacology Friday”, and other alliterative educational sessions

-   Journal Club - recurring weekly - twice monthly with current articles of interest, once monthly with classic content, and once monthly in collaboration with ATEAM

-   ATEAM - Academic Toxicology Education Alliance of the Mid-Atlantic. An exciting collaborative educational effort between our fellowship (NJPIES), the Maryland Poison Center, and The Philadelphia Poison Center. Provides core content lectures for students, rotators and fellows, a regional case conference, journal club, and more. Multiple opportunities for fellow engagement and presentation.

-   The American College of Medical Toxicology (ACMT) National Case Conference, along with the ACMT National Journal Club

-   Regular participation in the Rutgers University Hospital Department of Emergency Medicine Wednesday conference

 

Research Opportunities
Research opportunities abound at Rutgers. As part of the training, fellows are expected to explore and develop an area of interest and expertise, and utilize their training and mentorship to develop an original project. This scholarly pursuit can take many forms, from bench research to development of a curriculum, to grant-funded clinical trials. We have access to the full resources of the University, the experience of the faculty, and the research team in the Department of Emergency Medicine.
