Your heart sits in the middle of your chest and pumps blood from about 4 weeks after conception until the day that you die. It never stops, and over your lifetime it will pump ~175 million liters of blood. To visualize that, imagine the amount of water that falls over Niagara falls in a few minutes. Remarkable! This little pump is the size of your clenched fist and in an adult can weigh about 300 grams.

Current emergency care in Ghana is sub-optimal with significant delays to definitive care and high morbidity and mortality. The Ghanaian government has recently invested in physical infrastructure for emergency care at major teaching hospitals, but the human resources to provide care are inadequate. To address this need, the Ghana Emergency Medicine Collaborative has proposed an innovative training program focused on medical students, nurses, and residents with the formation of a new faculty for sustainable training. This program will train emergency medicine personnel in injury and acute medical illness management, expose trainees to research methodology, administrative and leadership aspects of emergency medicine. The Ghana Emergency Medicine Collaborative is a joint project between Kwame Nkrumah University of Science and Technology, Komfo Anokye Teaching Hospital, University of Michigan, Ghana Ministry of Health, Ghana College of Physicians and Surgeons, and Ghana Ambulance Service.

In 2009, the University of Michigan Department of Emergency Medicine working with global health partners at Komfo Anokye Teaching Hospital (KATH), Kwame Nkrumah University of Science and Technology (KNUST), Ghana College of Physicians and Surgeons, and the Ghana Ministry of Health established the Ghana Emergency Medicine Collaborative. The overall goal of the collaborative is to improve the provision of emergency care in Ghana through the development of physician, nursing and medical student training programs. This NIH-Fogarty International Center funded project also explores the use of new educational modalities such as open educational resources to provide education in Ghana. As part of this project, a 5-day Advanced Emergency Trauma Course (AETC) was constructed utilizing curricular materials from existing U.S. based emergency medicine residencies with modification to the available resources of developing Low-Middle Income Countries (LMICs) such as Ghana. The course, which was designed by University of Michigan and University of Utah Emergency Medicine Faculty includes 20 hours of didactic teaching material in open educational resource format, low-cost simulation models for procedural training and assessment tools. Attached are the full 20 hours of didactic materials in OER format.
