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 226 medical centers: 186 US and 40 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 the Massachusetts General Hospital in Boston. Dr. Carlos Camargo founded all programs, directs the ECC, and chairs the EMNet Steering Committee. Members of the ECC include Ashley Sullivan, Chu-Lin Tsai, Janice Espinola, Courtney Tierney, Sarah Arias, Kohei Hasegawa and Erica Ruggles. Members of the 2012-14 EMNet Steering Committee are Sunday Clark, Jeff Caterino, Jonathan Mansbach, Ashley Sullivan and Chu-Lin Tsai.
