Purpose: This study aimed to investigate the involvement of patients who died from hematologic neoplasms in the decision-making process surrounding the withdrawal of life-sustaining treatment (LST). Methods: A total of 255 patients diagnosed with hematologic neoplasms who ultimately died following decisions related to LST during their end-of-life period at a university hospital were included in the study. Data were retrospectively obtained from electronic medical records and analyzed utilizing the chi-square test, independent t-test, and logistic regression. Results: In total, 42.0% of patients participated in the decision-making process regarding LST for their hematologic neoplasms, while 58.0% of decisions were made with family involvement. Among these patients, 65.1% died in general wards and 34.9% in intensive care units (ICUs) as a result of decisions such as the suspension of LST. The period from the LST decision to death was longer when the decision was made by the patient (average, 27.15 days) than when it was made by the family (average, 7.48 days). Most decisions were made by doctors and family members in the ICU, where only 20.6% of patients exercised their right to make decisions regarding LST, a rate considerably lower than 79.4% observed in general wards. Decisions to withhold or withdraw LST were more commonly made by patients themselves than by their families. Conclusion: The key to discussing the decision to suspend hospice care and LST is respecting the patient's self-determination. If a patient is lucid prior to admission to the ICU, considerations about suspending LST should involve the patient input.
Delayed access to surgery may lead to deterioration in the patient condition, poor clinical outcomes, increase in the probability of emergency admission, or even death. The purpose of this work is to decide the number of patients selected from a waiting list and to schedule them in accordance with the operating room capacity in the next period. We formulate the problem as an infinite horizon Markov Decision Process (MDP), which attempts to strike a balance between the patient waiting times and overtime works. Structural properties of the proposed model are investigated to facilitate the solution procedure. The proposed procedure modifies the conventional value iteration method along with the binary search technique. An example of the optimal policy is provided, and computational results are given to show that the proposed procedure improves computational efficiency.

The purpose of this study is to examine whether there is a difference in the awareness of death based on happiness (since attitude or way of life differs among the general public, depending on the perception of death), and to investigate whether there is a difference in the interest in hospices between a group with a high happiness index and a group with a low happiness index. A survey was conducted on 200 men and women aged over 20 who participated in a walking event held in a metropolitan city on April 22, 2017. The survey consisted of eight demographic items: gender, age, education, occupation, marital status, family cohabitation, religion, and health status. It included 29 questions regarding happiness and nine questions regarding the perception of death. For the statistical tests, a chi-square test, an independent sample t-test, correlation analysis, and canonical correlation analysis were performed on the items of the survey based on a happiness index. The results of the study showed that, for a suitable place for death, medical institutions was the highest score (46.3%) for the group with a low happiness index, and own house was highest (59.4%) for the group with a high happiness index. This was a significant difference. It is thought that management systems should be supplemented by professional manpower, educating people so as to increase the utilization rates of home-based hospice as a way for patients to die in a comfortable and familiar place because, for Korea, death is much more common in hospitals. It is also necessary to increase the awareness of death and to make effective use of hospices through individual and various other approaches, considering the demographics of the subjects.
For patients who are near the end of life, an inevitable step is discussion of a do-not-resuscitate (DNR) order, which involves patients, their family members and physicians. To discuss DNR orders, patients and family members should know the meaning of the order and cardiopulmonary resuscitation (CPR) which includes chest compression, defibrillation, medication to restart the heart, artificial ventilation, and tube insertion in the respiratory tract. And the following issues should be considered as well: patients' and their families' autonomy, futility of treatment, and the right for death with dignity. Terminal cancer patients should be informed of what futility of treatment is, such as a low survival rate of CPR, unacceptable quality of life after CPR, and an irremediable disease status. In Korea, two different law suits related to life supporting treatments had been filed, which in turn raised public interest in death with dignity. Since the 1980s, knowledge of and attitude toward DNR among physicians and the public have been improved. However, most patients are still alienated from the decision making process, and the decision is often made less than a week before death. Thus, the DNR discussion process should be improved. Early palliative care should be adopted more widely.
Cancer is one of the major causes of death; however, the survival rate can be increased if discovered at an early stage for timely treatment. According to the statistics of the World Health Organization of 2002, breast cancer was the most prevalent cancer for all cancers occurring in women worldwide, and it account for 16.8% of entire cancers inflicting Korean women today. In order to classify the type of breast cancer whether it is benign or malignant, this study was conducted with the use of the discriminant analysis and the decision tree of data mining with the breast cancer data disclosed on the web. The discriminant analysis is a statistical method to seek certain discriminant criteria and discriminant function to separate the population groups on the basis of observation values obtained from two or more population groups, and use the values obtained to allow the existing observation value to the population group thereto. The decision tree analyzes the record of data collected in the part to show it with the pattern existing in between them, namely, the combination of attribute for the characteristics of each class and make the classification model tree. Through this type of analysis, it may obtain the systematic information on the factors that cause the breast cancer in advance and prevent the risk of recurrence after the surgery.
Purpose: The aim of this study is to carry out research on nurses regarding end of life decision and advance directives (ADs) and their attitude, experience and confidence towards them in order to define the role of nurses. Methods: In this research, questionnaire was distributed and data were collected and analyzed after receiving a written consent from 332 nurses. The survey was conducted from the $14^{th}$ to $30^{th}$ of September, 2009. The instrument used for conducting the study was revised version of KAESAD (The Knowledge, Attitudinal, Experiential Survey on Advance Directives). Results: We have come to a conclusion that nurses have positive attitude towards ADs. However, they hardly had any experience regarding them which leads to low confidence in assisting preparing ADs. Also, attitude towards ADs had no correlation with experience and confidence. Conclusion: In order to bring about the confidence level from positive attitude that nurses have, there needs to be a systematic change in nursing education. For that, it requires an education system that emphasizes the role of nurses which incorporates Korean culture and characteristics regarding death issue.
Purpose: The purpose of the study was to describe the experiences of do-not-resuscitate (DNR) among nurses. Methods: Data were collected by in-depth interviews with 8 nurses in 8 different hospitals. Conventional qualitative content analysis was used to analyze the data. Results: Eight major themes emerged from the analysis: DNR decision-making bypassing the patient, inefficiency in the decision-making process of DNR, negative connotation of DNR, predominance of verbal DNR over written DNR, doubts and confusion about DNR, least amount of intervention in the decision for DNR change of focus in the care of the patient after a DNR order, and care burden of patients with DNR. Decision-making of DNR occurred between physicians and family members, not the patients themselves. Often high medical expenses were involved in choosing DNR, thus if choosing DNR it was implied the family members and health professionals as well did not try their best to help the patient. Verbal DNR permission was more popular in clinical settings. Most nurses felt guilty and depressed about the dying/death of patients with DNR. Conclusion: Clearer guidelines on DNR, which reflect a family-oriented culture, need to be established to reduce confusion and to promote involvement in the decision-making process of DNR among nurses.
The first legislation for terminal health-care decision was California's Natural Death Act (NDA) of 1976 that permitted any adult person to execute a directive directing the withholding or withdrawal of life-sustaining procedures. Advance directive legislation has subsequently progressed on a state-by-state basis. By 1992, all 50 states, as well as the District of Columbia, had passed legislation to legalize some form of advance directive. This state legislation, however, has resulted in an often fragmented, incomplete, and sometimes inconsistent set of rules. Statutes enacted within a state often conflict and conflicts between statutes of different states are common. In an increasingly mobile society where an advance health-care directive given in one state must frequently be implemented in another, there is a need for greater uniformity. In 1993, the Uniform Law Commissioners approved the Uniform Health-Care Decisions Act (UHCDA) in order to bring order to the existing chaos. Unfortunately, the Commissioners waited too long to act. By the time the UHCDA was approved, nearly all states had passed legislation governing advance directives. Consequently, the UHCDA has achieved only a limited success, picking up but one or two enactments a year. The UHCDA is currently in effect in around 10 states: Alabama, Alaska, California, Delaware, Hawaii, Kansas, Maine, Mississippi, New Mexico, Tennessee, Wyoming. In these states the previous laws related to the subjects have been all repealed. The overall objective of the UHCDA is to encourage the making and enforcement of advance health care directives including living will or individual instruction, power of health-care attorney and to provide a means for making health care decisions for those who have failed to plan. The U. S. House of Representatives in 1991 enacted the Patient Self-Determination Act (PSDA). The Act stipulates that all hospitals receiving Medicaid or Medicare reimbursement must ascertain whether patients have or wish to have advance directives. The Patient Self- Determination Act does not create or legalize advance directives; rather it validates their existence in each of the states. Now in America, terminal health-care decision or advance directive for health care is common and universal system. The problem, however, is how to let more people use these good tools to make their lives more beautiful and honorable.

Purpose: This correlation study was performed to examine Korean adults' perceptions and attitudes towards death with dignity and the withdrawal of life sustaining treatment and to identify factors that predict their attitude towards death with dignity. Methods: The study was conducted using convenience sampling of 291 adults from three towns of a metropolitan city in Korea. Data were collected using structured questionnaires which surveyed people's perception about and attitudes towards withdrawal of life sustaining treatment and scaled their attitude towards death with dignity. Data were analyzed by using descriptive statistics, Pearson correlation coefficients and multiple regression. Results: The attitude towards the withdrawal of life sustaining treatment and death with dignity showed a significant positive correlation (r=0.49, P<0.001). For attitudes towards death with dignity, significant predictors were attitudes towards the withdrawal of life sustaining treatment, age, religion, a proper withdrawal process and advanced medical directives, which explained 49.3% of total variance. Conclusion: The results of this study may contribute to development of a new medical decision-making system including nurses' appropriate roles in the process of withdrawing life sustaining treatment and advanced medical directives.
The purpose of this study is to determine the inhibiting factors of dying well for people who want to have a good death. The final respondents in this study were sampled using stratified proportional allocation using a stratified random sampling method, and 1,000 adults aged between 19 and 75 years were selected. The questionnaire used consisted of four items on general characteristics and 20 items related to the inhibiting factors of dying well scored on a 7-point Likert scale. Analysis was conducted using descriptive statistics, correlation analysis, and decision tree analysis. Results showed that, among the inhibiting factors of dying well, "degenerative diseases (such as dementia)" and "loss of control (mental / physical)" scored 5.502 and 5.268 points, respectively; the highest significant positive correlation was found between "bad marital relationship" and "bad relationship with children," followed by "did not receive death education" and "lack of medical policy promotion (dying well)" and "bad relationship with children" and "indifference of others." Considering these findings, it appears that the whole society will make efforts to improve the perception and practice of good death, and life and death education will be expanded if death education for dying well is organized and implemented.
