The current Korean Mental Health Act (KMHA) indicates that a patient, who voluntarily gave their permission for admission into a mental health facility, has the right to be discharged upon personal request. However, there is no clause in the KMHA that allows a change in a patient's voluntary status under special circumstances. The purpose of this study was to investigate problems that may arise from the lack of such a clause ; problems that can result in misinterpretation and lead to the prohibition of voluntary admission status conversion.

Previous cases presented to the National Human Rights Commission of Korea were investigated in order to determine the current state in Korean psychiatric practice regarding the conversion from voluntary to involuntary admission status. In addition, examples of similar mental health legislation in use by the United Nations (UN), World Health Organization (WHO), and several advanced countries pertaining to such conversions were investigated. These examples were used as models for making recommendations for possible changes to the KMHA.

From 2010 to 2014, more than 220 petitions were filed with the National Human Right Commission of Korea. The petitions involved voluntarily institutionalized patients who had their requests for discharge rejected. Based on mental health regulations of the UN, WHO, and such countries as the United States, England, Canada, Australia, and Japan, the KMHA should include a provision that, upon receiving a discharge request, allows for discharge refusal if the voluntarily admitted patient is considered not mentally fit.

The results suggest that the absence of a regulation allowing admission status conversion in the current KMHA is inappropriate. Rectification of this absence is urgently needed.
