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 235 medical centers: 194 US and 41 International. 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 airway disorders.
  2. Health policy research, which includes the National ED Inventories (NEDI) and the National ED Safety Study (NEDSS).
  3. Other public health projects, focusing on public health issues that affect the delivery and quality of emergency care, as well as the primary care needs of medically disadvantaged populations. The ED Safety Assessment & Follow-up Evaluation (ED-SAFE), surveys, and analysis of federal 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. Members of the EMNet Coordinating Center include Jane Bittner, Janice Espinola, Catalina Gimenez-Zapiola, Erica Ruggles, Ashley Sullivan, Daphne Suzin, and Courtney Tierney. Members of the 2014-16 EMNet Steering Committee are Jeff Caterino, Sunday Clark, Jonathan Mansbach, and Ashley Sullivan.
