Emergency Medicine Network

Emergency Medicine Network

The Emergency Medicine Network's (EMNet) mission is to advance public health objectives through diverse projects in emergency care, particularly through multicenter clinical research.


EMNet involves 245 medical centers: 204 US and 41 International. Thousands of additional sites have completed EMNet surveys. The network focuses on three areas:

  1. Respiratory/allergy emergencies, through the Multicenter Airway Research Collaboration (MARC). MARC is an international research network focusing on asthma, COPD, anaphylaxis, bronchiolitis and other similar disorders.
  2. Health services research in emergency care, which includes the National ED Inventories (NEDI), patient safety, and workforce issues.
  3. Other public health projects, focusing on mental health emergencies and other public health issues. The ED Safety Assessment & Follow-up Evaluation (ED-SAFE), surveys, and analysis of large datasets are the core activities of this program.

All EMNet programs are based at the EMNet Coordinating Center (ECC) at Massachusetts General Hospital in Boston. Dr. Carlos Camargo founded all programs, directs the ECC, and chairs the EMNet Steering Committee. Ashley Sullivan is Associate Director of EMNet. Investigators include Kohei Hasegawa, Maggie Samuels-Kalow, and Kori Zachrison. Members of the EMNet Coordinating Center include Vanessa Annulysse, Krislyn Boggs, Erin Crocker, Kathryn Entner, Janice Espinola, Catalina Gimenez-Zapiola, Daphne Suzin, and Courtney Tierney. Members of the 2016-18 EMNet Steering Committee are Jeff Caterino, Sunday Clark, Jonathan Mansbach, and Ashley Sullivan.
