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 246 medical centers and three programs. Large administrative dataset analyses contribute to all three programs.

  1. Multicenter Airway Research Collaboration (MARC) is an international research network focusing on respiratory/allergy emergencies such as asthma, COPD, anaphylaxis, bronchiolitis and other similar disorders.
  2. Health Services Research (HSR) focuses on access to emergency care, quality of emergency care, and patient outcomes. This includes the National ED Inventories (NEDI) along with patient safety and workforce studies.
  3. Public Health includes diverse topics, but focuses on mental health emergencies such as the ED Safety Assessment & Follow-up Evaluation (ED-SAFE) and large surveys.

All EMNet programs are based at the EMNet Coordinating Center (ECC) at Massachusetts General Hospital in Boston. Dr. Carlos Camargo founded all programs, is the EMNet Division Chief, and chairs the EMNet Steering Committee. Ashley Sullivan is the Director of the ECC. Investigators include Kohei Hasegawa, Maggie Samuels-Kalow, and Kori Zachrison.

Key members of the current EMNet Coordinating Center include Krislyn Boggs, MPH (Senior Research Coordinator) and Janice Espinola, MPH (Biostatistician/Epidemiologist). Members of the EMNet Steering Committee are Jeff Caterino, Sunday Clark, Robert Freishtat, Kohei Hasegawa, Jonathan Mansbach, and Ashley Sullivan.
