MARC-35 (also known as the WIND Study) is a multicenter, prospective cohort study of severe bronchiolitis and risk of recurrent wheezing. Please contact Dr. Carlos Camargo if you would like additional details.

MARC-41 will build on the success of the MARC-36 and -37 studies by implementing an evidenced-based hospital-initiated care bundle and evaluating its effectiveness at five geographically-diverse US sites.

MARC-42 is an AHRQ-funded analysis of large administrative datasets (i.e., Medicare and State Inpatient Databases) and survey data (i.e., NHANES and MCBS) to investigate readmissions within 30 days after COPD-related hospitalization and comparative effectiveness in COPD management. Please contact Drs. Carlos Camargo or Kohei Hasegawa if you would like additional details.

MARC-43 (also known as the CHIME Study) is a multicenter, prospective cohort study of healthy infants’ respiratory microbiome. Please contact Dr. Carlos Camargo if you would like additional details.

EMNet has teamed up with the R Baby Foundation again to perform its fourth annual national survey to better understand the nature of U.S. emergency departments (EDs). Briefly, we are contacting hospitals to obtain basic information about their EDs.

The results from this national survey will be used to perform health policy research on U.S. emergency care and to enhance our existing app, EMNet findERnow (available for free on both iPhone and Android smartphones). If you have questions or would like more information, please contact our office at 617-724-4069 or email us at

NEDI-New England surveys EDs in all 6 New England states: Connecticut, Massachusetts, Maine, New Hampshire, Rhode Island, and Vermont. The survey will collect information regarding ED characteristics, staffing, electronic resources, consultant availability, health-related social needs, and opioid management.

The Pediatric Emergency Care Coordinator (PECC) Initiative was an EMNet campaign to establish a physician and/or nursing Pediatric Emergency Care Coordinator (PECC) in 100% of Massachusetts EDs by October 2017.

Based on the success in Massachusetts, EMNet aims to use this as a model for helping other states to expand establishment of PECCs in their EDs.

To learn more about the PECC Initiative, please contact Krislyn Boggs.

Health-related social needs (HRSN), such as hunger and homelessness, influence patients’ decisions to present to the ED and their ability to adhere to treatment. The goals of this project are to understand the relationship between HRSN and potentially preventable visits, to pilot a brief screener for HRSN in the ED, and to develop and pilot a tool for patients with HSRN that can be broadly generalizable to other EDs.

Please contact Dr. Maggie Samuels-Kalow if you would like additional details.

EMNet investigators are investigating the role of telemedicine in emergency care, both regionally and nationally. Recent studies are exploring the role of telemedicine in pediatric emergencies and mental health emergencies; we also are investigating barriers (and solutions) for the use of telemedicine in rural EDs.

Please contact Dr. Kori Zachrison if you would like additional details.

Large administrative dataset analyses contribute to all three research programs at EMNet. To learn more about these diverse analyses, please click here.
