Angkor Hospital for Children recognizes the importance of evidence-based medicine, obtaining data specific to Cambodia and sharing findings to health care workers. We collect high-quality, reliable data that can be used to create medical and health procedures and recommendations that will be most effective for the Cambodian population.
AHC has been involved in independent and collaborative research. Partners have included: Wellcome Trust (UK), Mahidol University (Thailand), Brown University (USA), Médécins Sans Frontières (France), and University of California, San Francisco (USA).
Recognizing the importance of confidentiality and the need to protect patients from undue harm, the hospital established an Internal Review Board (IRB) in 2004. The IRB has been certified by the U.S. Department of Health and Human Services and Federal Wide Assurance for the Protection of Human Subjects for International (Non-U.S.) Institutions.
A complete list of published research, as well as current studies, is available.
