Ethical oversight in the form of review boards and research ethics committees provide protection for research subjects as well as guidance for safe conduct of studies. As the number of collaborative emergency care research studies carried out in low- and middle-income countries increases, it is crucial to have a shared understanding of how ethics should inform choice of study topic, study design, methods of obtaining consent, data management, and access to treatment after closure of the study. This paper describes the basic principles of Western research ethics – respect for persons, beneficence, and justice - and how the principles may be contextualized in different settings, by researchers of various backgrounds with different funding streams. Examples of lapses in ethical practice of research are used to highlight best practices.
