However, only 20~25% of deaths of terminally ill patients comply with the law, while the remaining 75~80% do not. There is significant confusion in how the law distinguishes between those in the terminal stage and those in the dying process. These 2 stages can be hard to distinguish, and they should be understood as a single unified \"terminal stage.\" The number of medical institutions eligible for life-sustaining treatment decisions should be legally expanded to properly reflect patients' wishes. To prevent unnecessary suffering resulting from futile life-sustaining treatment, life-sustaining treatment decisions for terminal patients without the needed familial relationships should be permitted and made by hospital ethics committees. Adult patients should be permitted to assign a legal representative appointed in advance to represent them. Medical records can be substituted for a patient's judgment letter (No. 9) and an implementation letter (No. 13) for the decision to suspend life-sustaining treatment. Forms 1, 10, 11, and 12 should be combined into a single form. The purpose of the Life-sustaining Medical Decisions Act is to respect patients' right to self-determination and protect their best interests. Issues related to the act that have emerged in the 3 years since its implementation must be analyzed, and a plan should be devised to improve upon its shortcomings.</p>","PeriodicalId":73780,"journal":{"name":"Journal of hospice and palliative care","volume":"25 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/60/44/jhpc-25-1-1.PMC10180009.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10171088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the quality of death, it is necessary to prepare for death, allowing patients to die comfortably and with dignity at the end. Considering these issues, I aim to discuss the practical aspects of notifying the patient of the terminal phase of cancer and planning for end-of-life care (i.e., advance care planning). When cancer treatment that can extend the patent's lifespan becomes difficult, the patient enters a treatment transition period. Treatment is shifted from life-prolonging care to life-enhancing care, and end-of-life care must be well planned. Medical providers often worry too much about whether the patient will be disappointed or psychologically traumatized when notified of the terminal phase of their cancer, thus delaying plans for end-of-life care. In fact, patients can accept their condition and prepare for end-of-life care better than we expect. During the treatment transition period, notification of terminal status should be given, and a well-prepared advance care plan should be established early when the patient has decision-making ability. In addition to conveying information, it is always necessary to be sensitive to whether the patient and caregiver understand the information and respond to their emotions.</p>","PeriodicalId":73780,"journal":{"name":"Journal of hospice and palliative care","volume":"25 1","pages":"42-49"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/21/60/jhpc-25-1-42.PMC10180006.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10179926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
