OBJECTIVES: Currently, active euthanasia is legalized in only 7 countries worldwide. These countries have encountered problems in its implementation. The study aims to summarize the practical clinical problems in the literature on active euthanasia. METHODS: A systematic literature review was conducted using 140 works consisting of 130 articles from PubMed and EthxWeb and data from 10 euthanasia laws. RESULTS: After reviewing the specific problems reported to be associated with euthanasia in each country, 5 problems were extracted: many ambiguous conditions with room for interpretation, insufficient assurance of voluntariness, response to requests for euthanasia due to psychological distress, conscientious objection, and noncompliance by medical professionals. SIGNIFICANCE OF RESULTS: Multiple ambiguous conditions that are open to interpretation can result in a "slippery slope phenomenon." An insufficient guarantee of voluntariness violates the principle of respect for autonomy, which is the underlying justification for euthanasia. In cases of euthanasia due to mental anguish, a distinction between a desire for death caused by psychological pain alone prompted by mental illness and a desire for death caused by mental symptoms prompted by physical illness is essential. Conscientious objection should remain an option because of the heavy burden placed on doctors who perform euthanasia. Noncompliance by medical professionals due to ignorance and conflicts regarding euthanasia is contrary to procedural justice.
