Lenox Hill International Emergency Medicine Outreach Program

Our mission is to improve Emergency Medical Care in developing nations where the specialty is in its infancy by assessing needs and capacity and implementing stable improvements.

Where We Work

Over the past two years, Lenox Hill has sent several teams of physicians and nurses to Peru to volunteer their services and expertise while working alongside local healthcare providers. Peru is a country of approximately 32 million people with only 7-8 Emergency Medicine (EM) training programs and a handful of EM trained physicians. The health care system in Peru is government run, under-funded, and antiquated. While healthcare in Peru’s capital, Lima, is improving rapidly, there are striking disparities once outside of the city that require identification and improvement.

Past Volunteer Trips

  • July 2012: A team of volunteer healthcare providers was sent down to the impoverished Mala region, were they provided basic medical supplies donated by Lenox Hill. The team worked with Health Bridges International (a NGO based out of Portland, Oregon) to provide primary medical care in makeshift clinics for a two week period.
  • April 2013: Program director, Justin Mazur MD, participated in a series of multidisciplinary community planning meetings in Alto Caymo, Peru. The meetings addressed the area’s poor access to healthcare and lack of infrastructure. The meetings resulted in the development of a community healthcare worker program with training in Basic Life Support (BLS) and in the identification of public health concerns in the community.
  • July 2013: A team of volunteer health care providers returned to the Mala region again bringing medical supplies and volunteering in primary care clinics. The group also gave a grand rounds presentation to health care providers in Ica, Peru on common obstetrical emergencies.
  • September 2013: Dr. Mazur returned to Peru to deliver a grand rounds lecture on pediatric fever and meet with leadership from Emergency Departments throughout Peru’s largest metropolitan areas (Lima, Ica, and Arequipe) to assess EM capacity. Hospitals in Ica were identified as the best place to start collaborating on the improvement of Emergency Care.
  • February 2014: Dr. Mazur and Dr. Abel Romero, a Peruvian ED physician, delivered a 2 day seminar on ACLS and Advanced Airway Management.  Attendees included Physicians and Nurses from three hospitals located in Ica, Peru with little to no training in ACLS and Advanced Airway Management who are currently working in the Emergency Rooms.  Lenox Hill Hospital donated essential emergency airway adjuncts such as bougies and nasal cannulas, widely available in the US, yet not available in Peru.

Further Steps

We are currently working with Peruvian EM physicians to build EM capacity.   We are working with a small, but growing Peruvian EM organization, AMEDAL, to improve and to develop into a larger, national Academic Academy of Emergency Physicians.   Currently, AMEDAL is applying for affiliation into the International Federation of Emergency Medicine (IFEM).  We plan to continue working clinically and giving academic seminars and plan to begin sending EM residents from LIJ and other New York hospitals to work side by side with out Peruvian colleagues.
