Ethical issues in emergency medicine often are accompanied by legal issues. Although the legal aspects of an ethical problem are important factors to take into consideration, the law may riot directly address the problem, and following the law does not always ensure an ethical outcome. Emergency physicians should have an understanding of ethics and law, understand the legal aspects of bioethical issues in emergency medicine, and finally have a guide to analyze ethical issues, including the consideration of legal issues that may have an impact on the case.
