Implication of the Life-Sustaining Treatment Decisions Act on End-of-Life Care for Korean Terminal Patients

Inpatient Hospice Care in Korea during the COVID-19 Pandemic: A Preliminary Study

Purpose

This study examined the quality of life (QoL) and quality of care (QoC) in inpatient hospice settings in Korea before and during the coronavirus disease 2019 (COVID-19) pandemic.

Methods

Data were obtained from three institutions that participated in two prospective cohort studies. The primary outcomes measured were the QoL of patients with terminal cancer and their family caregivers (FCs), as well as the QoC as perceived by the FCs.

Results

Multivariable regression analysis revealed that during the COVID-19 pandemic, both patients and FCs experienced better QoL than before the pandemic, and FCs reported a higher QoC.

Conclusion

Health policymakers should consider our findings when planning for future pandemics.

Comparison of factors influencing the decision to withdraw life-sustaining treatment in intensive care unit patients after implementation of the Life-Sustaining Treatment Act in Korea

BACKGROUND

The decision to discontinue intensive care unit (ICU) treatment during the end-oflife stage has recently become a significant concern in Korea, with an observed increase in life-sustaining treatment (LST) withdrawal. There is a growing demand for evidence-based support for patients, families, and clinicians in making LST decisions. This study aimed to identify factors influencing LST decisions in ICU inpatients and to analyze their impact on healthcare utilization.

METHODS

We retrospectively reviewed medical records of ICU patients with neurological disorders, infectious disorders, or cancer who were treated at a single university hospital between January 1, 2019 and July 7, 2021. Factors influencing the decision to withdraw LST were compared between those who withdrew LST and those who did not.

RESULTS

Among 54,699 hospital admissions, LST was withdrawn in 550 cases (1%). Cancer was the most common diagnosis, followed by pneumonia and cerebral infarction. Among ICU inpatients, LST was withdrawn from 215 (withdrawal group). The withdrawal group was older (78 vs. 75 years, P=0.002), had longer total hospital stays (16 vs. 11 days, P<0.001), and higher ICU readmission rates than the control group. There were no significant differences in the healthcare costs of ICU stay between the two groups. Most LST decisions (86%) were made by family.

CONCLUSIONS

The decisions to withdraw LST of ICU inpatients were influenced by age, readmission, and disease category. ICU costs were similar between the withdrawal and control groups. Further research is needed to tailor LST decisions in the ICU.

Characteristics and outcomes of patients with do-not-resuscitate and physician orders for life-sustaining treatment in a medical intensive care unit: a retrospective cohort study

BACKGROUND

In the intensive care unit (ICU), we may encounter patients who have completed a Do-Not-Resuscitate (DNR) or a Physician Orders to Stop Life-Sustaining Treatment (POLST) document. However, the characteristics of ICU patients who choose DNR/POLST are not well understood.

METHODS

We retrospectively analyzed the electronic medical records of 577 patients admitted to a medical ICU from October 2019 to November 2020, focusing on the characteristics of patients according to whether they completed DNR/POLST documents. Patients were categorized into DNR/POLST group and no DNR/POLST group according to whether they completed DNR/POLST documents, and logistic regression analysis was used to evaluate factors influencing DNR/POLST document completion.

RESULTS

A total of 577 patients were admitted to the ICU. Of these, 211 patients (36.6%) had DNR or POLST records. DNR and/or POLST were completed prior to ICU admission in 48 (22.7%) patients. The DNR/POLST group was older (72.9 ± 13.5 vs. 67.6 ± 13.8 years, p < 0.001) and had higher Acute Physiology and Chronic Health Evaluation (APACHE) II score (26.1 ± 9.2 vs. 20.3 ± 7.7, p < 0.001) and clinical frailty scale (5.1 ± 1.4 vs. 4.4 ± 1.4, p < 0.001) than the other groups. Solid tumors, hematologic malignancies, and chronic lung disease were the most common comorbidities in the DNR/POLST groups. The DNR/POLST group had higher ICU and in-hospital mortality and more invasive treatments (arterial line, central line, renal replacement therapy, invasive mechanical ventilation) than the other groups. Body mass index, APAHCE II score, hematologic malignancy, DNR/POLST were factors associated with in-hospital mortality.

CONCLUSIONS

Among ICU patients, 36.6% had DNR or POLST orders and received more invasive treatments. This is contrary to the common belief that DNR/POLST patients would receive less invasive treatment and underscores the need to better understand and include end-of-life care as an important ongoing aspect of patient care, along with communication with patients and families.

Recent Trends in the Withdrawal of Life-Sustaining Treatment in Patients with Acute Cerebrovascular Disease : 2017-2021

OBJECTIVE

The Act on Life-Sustaining Treatment (LST) decisions for end-of-life patients has been effective since February 2018. An increasing number of patients and their families want to withhold or withdraw from LST when medical futility is expected. This study aimed to investigate the status of the Act on LST decisions for patients with acute cerebrovascular disease at a single hospital.

METHODS

Between January 2017 and December 2021, 227 patients with acute cerebrovascular diseases, including hemorrhagic stroke (n=184) and ischemic stroke (n=43), died at the hospital. The study period was divided into the periods before and after the Act.

RESULTS

The duration of hospitalization decreased after the Act was implemented compared to before (15.9±16.1 vs. 11.2±18.6 days, p=0.127). The rate of obtaining consent for the LST plan tended to increase after the Act (139/183 [76.0%] vs. 27/44 [61.4%], p=0.077). Notably, none of the patients made an LST decision independently. Ventilator withdrawal was more frequently performed after the Act than before (52/183 [28.4%] vs. 0/44 [0%], p<0.001). Conversely, the rate of organ donation decreased after the Act was implemented (5/183 [2.7%] vs. 6/44 [13.6%], p=0.008). Refusal to undergo surgery was more common after the Act was implemented than before (87/149 [58.4%] vs. 15/41 [36.6%], p=0.021) among the 190 patients who required surgery.

CONCLUSION

After the Act on LST decisions was implemented, the rate of LST withdrawal increased in patients with acute cerebrovascular disease. However, the decision to withdraw LST was made by the patient's family rather than the patient themselves. After the execution of the Act, we also observed an increased rate of refusal to undergo surgery and a decreased rate of organ donation. The Act on LST decisions may reduce unnecessary treatments that prolong end-of-life processes without a curative effect. However, the widespread application of this law may also reduce beneficial treatments and contribute to a decline in organ donation.

Patient and hospital characteristics associated with do-not-resuscitate/do-not-intubate orders: a cross-sectional study based on the Taiwan stroke registry

BACKGROUND

Previous studies of do-not-resuscitate (DNR) or do-not-intubate (DNI) orders in stroke patients have primarily been conducted in North America or Europe. However, characteristics associated with DNR/DNI orders in stroke patients in Asia have not been reported.

METHODS

Based on the Taiwan Stroke Registry, this nationwide cross-sectional study enrolled hospitalized stroke patients from 64 hospitals between 2006 and 2020. We identified characteristics associated with DNR/DNI orders using a two-level random effects model.

RESULTS

Among the 114,825 patients, 5531 (4.82%) had DNR/DNI orders. Patients with acute ischemic stroke (AIS) had the highest likelihood of having DNR/DNI orders (adjusted odds ratio [aOR] 1.76, 95% confidence interval [CI] 1.61-1.93), followed by patients with intracerebral hemorrhage (ICH), and patients with subarachnoid hemorrhage (SAH) had the lowest likelihood (aOR 0.53, 95% CI 0.43-0.66). From 2006 to 2020, DNR/DNI orders increased in all three types of stroke. In patients with AIS, women were significantly more likely to have DNR/DNI orders (aOR 1.23, 95% CI 1.15-1.32), while patients who received intravenous alteplase had a lower likelihood (aOR 0.74, 95% CI 0.65-0.84). Patients with AIS who were cared for by religious hospitals (aOR 0.55, 95% CI 0.35-0.87) and patients with SAH who were cared for by medical centers (aOR 0.40, 95% CI 0.17-0.96) were significantly less likely to have DNR/DNI orders.

CONCLUSIONS

In Taiwan, DNR/DNI orders increased in stroke patients between 2006 and 2020. Hospital characteristics were found to play a significant role in the use of DNR/DNI orders.

Advance Care Planning in South Korea

South Korea is an Asian country with a very low birth rate and a large elderly population. Nearly half of deaths are in the elderly over the age of 80, and cancer is the leading cause of all deaths. As the aging population increases, interest in end-of-life (EOL) care and quality of death is growing, but South Korea is one of the Asian countries that traditionally feels burdened by discussing death openly. In particular, even when a person is suffering from an incurable disease and is about to die, it is customary for the family members to make decisions without directly informing the patient of the disease status or discussing life-sustaining treatment (LST). However, due to a series of social events, the importance of individual autonomy, good death, discontinuation of LSTs, and advance care planning (ACP) gradually spread, and eventually the Life-Sustaining Treatment Decisions Act was implemented in 2018. With the enactment of this law, patients' autonomy was enhanced in a short period of time, and a legal basis was established to discontinue LST at the EOL. However, there are still many areas to be improved, and it is fundamentally necessary to spread the concept of 'ACP' within society.

Preferred versus Actual Place of Care and Factors Associated with Home Discharge among Korean Patients with Advanced Cancer: A Retrospective Cohort Study

Respecting the preference for a place of care is essential for advance care planning in patients with advanced cancer. This retrospective study included adult patients with cancer referred to an inpatient palliative care consultation team at a tertiary acute care hospital in South Korea between April 2019 and December 2020. Patients' preference for place of care and demographic and clinical factors were recorded, and the actual discharge locations were categorized as home or non-home. Patients discharged home but with unintended hospital visits within 2 months were also investigated. Of the 891 patients referred to the palliative care consultation team, 210 (23.6%) preferred to be discharged home. Among them, 113 (53.8%) were discharged home. No significant differences were found between patients who preferred home discharge and those who did not. Home discharge was higher among female patients (p = 0.04) and lower in those with poor oral intake (p < 0.001) or dyspnea (p = 0.02). Of the 113 patients discharged home, 37 (32.8%) had unintended hospital visits within 2 months. Approximately one-quarter of hospitalized patients with advanced cancer preferred to be discharged home, but only half of them received the home discharge. To meet patients' preferences for end-of-life care, individual care planning considering relevant factors is necessary.

Participation and Influencing Factors in the Decision-Making of Life-Sustaining Treatment: A Focus on Deceased Patients with Hematologic Neoplasms

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.

Modification of termination of resuscitation rule with compression time interval in South Korea

This study aimed to validate the predictive performance of the termination of resuscitation (TOR) rule and examine the compression time interval (CTI) as a criterion for modifying the rule. This retrospective observational study analyzed adult out-of-hospital cardiac arrest (OHCA) patients attended by emergency medical service (EMS) providers in mixed urban-rural areas in Korea in 2020 and 2021. We evaluated the predictive performance of basic life support (BLS) and the Korean Cardiac Arrest Research Consortium (KoCARC) TOR rule using the false-positive rate (FPR) and positive predictive value (PPV). We modified the age cutoff criterion and examined the CTI as a new criterion. According to the TOR rule, 1827 OHCA patients were classified into two groups. The predictive performance of the BLS TOR rule had an FPR of 11.7% (95% confidence interval (CI): 5.9-17.5) and PPV of 98.4% (97.6-99.2) for mortality, and an FPR of 3.6% (0.0-7.8) and PPV of 78.6% (75.9-81.3) for poor neurological outcomes at hospital discharge. The predictive performance of the KoCARC TOR rule had an FPR of 5.0% (1.1-8.9) and PPV of 98.9% (98.0-99.8) for mortality, and an FPR of 3.7% (0.0-7.8) and PPV of 50.0% (45.7-54.3) for poor neurological outcomes at hospital discharge. The modified cutoff value for age was 68 years, with an area under the receiver operating characteristic curve over 0.7. In the group that met the BLS TOR rule, the cutoff of the CTI for death was not determined and was 21 min for poor neurological outcomes. In the group that met the KoCARC TOR rule, the cutoff of the CTI for death and poor neurological outcomes at the time of hospital discharge was 25 min and 21 min, respectively. The BLS TOR and KoCARC TOR rules showed inappropriate predictive performance for mortality and poor neurological outcomes. However, the predictive performance of the TOR rule could be supplemented by modifying the age criterion and adding the CTI criterion of the KoCARC.

Epidemiology of patients who died in the emergency departments and need of end-of-life care in Korea from 2016 to 2019

The need of palliative care at the end-of-life in the emergency departments (ED) is growing. The study aims to investigate the epidemiology of patients who died during care in ED using nationwide database, and to estimate the need for palliative care in the ED. A retrospective observational study was conducted using the National Emergency Department Information System (NEDIS) database. Patients who died during ED care between 2016 and 2019 were included. Palliative care-eligible disease was defined as cancer (C00-C99 of ICD-10), chronic respiratory disease (CRD, J44-J46), chronic liver disease (CLD, K70-K77), and heart failure (HF, I50). Among the 36,538,486 ED visits during 4 years, 34,086 ED deaths were included. The crude incidence rate of ED deaths per 100,000 person-year was steady between 16.6 in 2016 and 16.3 in 2019 (p-for-trend = 0.067). Only 3370 (9.9%) ED deaths were injury, while 30,716 (90.1%) deaths were related to diseases. The most common ED diagnosis was cardiac arrest (22.1%), followed by pneumonia (8.6%) and myocardial infarction (4.7%). In cases of disease-related ED deaths, about 34.0% stayed longer than 8 h in the ED (median (interquartile range): 4.5 (1.9-11.7) h) and 44.2% received cardiopulmonary resuscitation (CPR) at end-of-life time. A quarter of the disease-related ED deaths were diagnosed with palliative care eligible disease: cancer (16.9%), CLD (3.8%), HF (3.5%), and CRD (1.4%). Cancer patients received less CPR (23.4%) and stayed longer in the ED (median (interquartile range): 7.3 (3.2-15.9) h). Over the past 4 years, more than 30,000 patients, including 5200 cancer patients, died during care in the ED. A quarter of disease-related ED death were patients with palliative care-eligible condition and more than 30% of them stayed longer than 8 h in the ED before death. It is time to discuss about need of palliative care in the ED.

Association of perceived life satisfaction with attitudes toward life-sustaining treatment among the elderly in South Korea: a cross-sectional study

BACKGROUND

Amidst rapid population aging, South Korea enacted the Well-dying Act, late among advanced countries, but public opinion on the act is not still clear. Against this background, this study aims to: 1) investigate factors affecting elderly individuals' attitude toward life-sustaining treatment, and 2) examine whether attitude toward life-sustaining treatment is related to their perceived life satisfaction.

METHODS

Data from the 2020 Survey of Living Conditions and Welfare Needs of Korean Older Persons were used. There were 9,916 participants (3,971 males; 5,945 females). We used multivariable-adjusted Poisson regression models with robust variance to examine the association between perceived life satisfaction and attitude toward life-sustaining treatment and calculate prevalence ratios (PR) and 95% confidence intervals (CI).

RESULTS

After adjusting potential confounders, the probabilities that the elderly who were dissatisfied with their current life would favor life-sustaining treatment were 1.52 times (95% CI: 1.15-1.64) and 1.28 times (95% CI: 1.09-1.51) higher for men and women, respectively, than the elderly who were satisfied. In addition, attitudes in favor of life-sustaining treatment were observed prominently among the elderly with long schooling years or high household income, when they were dissatisfied with their life.

CONCLUSIONS

Our results suggested that for the elderly, life satisfaction is an important factor influencing how they exercise their autonomy and rights regarding dying well and receiving life-sustaining treatment. It is necessary to introduce interventions that would enhance the life satisfaction of the elderly and terminally ill patients and enable them to make their own decisions according to the values of life.

The Medical Needs and Characteristics of Cancer and Progressive Neurologic Disease Patients Who Use Home-Based Medical Care in Korea: A Retrospective Study for 2011-2020

OBJECTIVES

To investigate the needs and characteristics of patients with cancer and neurologic disorders requiring home-based medical care (HBMC).

DESIGN

Retrospective observational study.

SETTING AND PARTICIPANTS

Patients receiving HBMC on discharge from a tertiary hospital in Korea during 2011-2020.

METHODS

Patients were classified into 3 disease groups: cancer, progressive neurologic disorders (NR), and others. Characteristics and medical needs were assessed in each disease group. Medical needs were categorized based on functional items requiring support or management at the time of registration: respiratory, feeding, urinary system, drain tube, central catheter, wound, medication, and other. Patients with multiple medical needs were assigned to multiple categories. Patients who used HBMC for more than 3 months were defined as long-term users; their characteristics were evaluated in the same way.

RESULTS

Of the total 655 patients, 47.0% (308) had cancer and 17.3% (113) were NR patients. Among all patients, 78.8% were partially dependent (44.0%) or completely dependent (34.8%) in daily activities, and there were more dependent patients in the NR group (80.5%) than cancer (26.6%). Patients with cancer needed central catheter management the most (43.5%), followed by wound care (36.7%), feeding support (35.1%), and drain tube management (22.1%). NR patients required feeding support the most (80.5%), followed by respiratory support (43.4%), wound care (41.6%), and urinary system support (19.5%). Of all patients, 30.2% (198) were long-term users (NR, 37.9%; cancer, 35.4%). Long-term users were common among patients who needed respiratory support (59.4%), feeding support (48.75), and urinary system support (34.6%).

CONCLUSIONS AND IMPLICATIONS

Homebound patients with cancer and progressive neurologic disorders need medical services at home after discharge. Patients who need feeding and respiratory support usually use HBMC for more than 3 months. Further studies are needed to design an optimal HBMC that continuously provides medical services to patients with serious illnesses living at home.

Use of antimicrobial agents in actively dying inpatients after suspension of life-sustaining treatments: Suggestion for antimicrobial stewardship

BACKGROUND

The role of antimicrobial treatment in end-of-life care has been controversial, whether antibiotics have beneficial effects on comfort and prolonged survival or long-term harmful effects on increasing antimicrobial resistance. We assessed the use of antimicrobial agents and factors associated with de-escalation in inpatients who suspended life-sustaining treatments (SLST) and immediately died.

METHODS

We included 1296 (74.7%) inpatients who died within 7 days after SLST out of 1734 patients who consented to SLST on their own or family's initiative following a decision by two physicians, observing the "Life-sustaining Treatment Decision Act" between January 2020 and December 2020 at two teaching hospitals. De-escalation was defined as changing to narrower spectrum anti-bacterial drugs or stopping ≥ one antibiotic of combined treatment.

RESULTS

90.6% of total patients received anti-bacterial agents, particularly a combination treatment in 60.1% and use of ≥ three drugs in 18.2% of them. Antifungal and antiviral drugs were administered to 12.6% and 3.3% of the patients on SLST, respectively. Antibacterial and antifungal agents were withdrawn in only 8.3% and 1.3% of the patients after SLST, respectively. Anti-bacterial de-escalation was performed in 17.0% of patients, but 43.6% of them received more or broad-spectrum antibiotics after SLST. In multivariate regression, longer hospital stays before SLST, initiation of SLST in the intensive care unit, and cardiovascular diseases were independently associated with anti-bacterial de-escalation after SLST.

CONCLUSIONS

The intervention for substantial antibiotic use in patients on SLST should be carefully considered as antimicrobial stewardship after decision by the will of the patient and proxy.

Aggressiveness of care in the last days of life in the emergency department of a tertiary hospital in Korea

Background

High-quality end-of-life (EOL) care requires both comfort care and the maintenance of dignity. However, delivering EOL in the emergency department (ED) is often challenging. Therefore, we aimed to investigate characteristics of EOL care for dying patients in the ED.

Methods

We conducted a retrospective cohort study of patients who died of disease in the ED at a tertiary hospital in Korea between January 2018 and December 2020. We examined medical care within the last 24 h of life and advance care planning (ACP) status.

Results

Of all 222 disease-related mortalities, 140 (63.1%) were men, while 141 (63.5%) had cancer. The median age was 74 years. As for critical care, 61 (27.5%) patients received cardiopulmonary resuscitation, while 80 (36.0%) received mechanical ventilation. The absence of serious illness (p = 0.011) and the lack of an advance statement (p < 0.001) were both independently associated with the receipt of more critical care. Only 70 (31.5%) patients received comfort care through opioids. Younger patients (< 75 years) (p = 0.002) and those who completed life-sustaining treatment legal forms (p = 0.001) received more comfort care. While EOL discussions were initiated in 150 (67.6%) cases, the palliative care team was involved only in 29 (13.1%).

Conclusions

Patients in the ED underwent more aggressive care and less comfort care in a state of imminent death. To ensure better EOL care, physicians should minimize redundant evaluations and promptly introduce ACP.

Problems Related to the Act on Decisions on Life-Sustaining Treatment and Directions for Improvement

The Act on Decisions on Life-Sustaining Treatment has been in effect since 2018 for end-of-life patients. 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.

Life-Sustaining Treatment States in Korean Cancer Patients after Enforcement of Act on Decisions on Life-Sustaining Treatment for Patients at the End of Life

PURPOSE

In Korea, the "Act on Hospice and Palliative Care and Decisions on Life-sustaining Treatment for Patients at the End of Life" was enacted on February 4, 2018. This study was conducted to analyze the current state of life-sustaining treatment decisions based on National Health Insurance Service (NHIS) data after the law came into force.

MATERIALS AND METHODS

The data of 173,028 cancer deaths were extracted from NHIS qualification data between November 2015 and January 2019.

RESULTS

The number of cancer deaths complied with the law process was 14,438 of 54,635 cases (26.4%). The rate of patient self-determination was 49.0%. The patients complying with the law process have used a hospice center more frequently (28% vs. 14%). However, the rate of intensive care unit (ICU) admission was similar between the patients who complied with and without the law process (ICU admission, 23% vs. 21%). There was no difference in the proportion of patients who had undergone mechanical ventilation and hemodialysis in the comparative analysis before and after the enforcement of the law and the analysis according to the compliance with the law. The patients who complied with the law process received cardiopulmonary resuscitation at a lower rate.

CONCLUSION

The law has positive effects on the rate of life-sustaining treatment decision by patient's determination. However, there was no sufficient effect on the withholding or withdrawing of life-sustaining treatment, which could protect the patient from unnecessary or harmful interventions.

Current Status and Cardinal Features of Patient Autonomy after Enactment of the Life-Sustaining Treatment Decisions Act in Korea

Purpose

The main purpose of the Life-Sustaining Treatment Decisions Act recently enacted in Korea is to respect the patient’s self-determination. We aimed to investigate the current status and features of patient self-determination after implementation of the law.

Materials and Methods

Between February 2018 and January 2019, 54,635 cancer deaths were identified from the National Health Insurance Service (NHIS) database. We analyzed the characteristics of decedents who complied with the law process by self-determination compared with decedents with family determination and with decedents who did not comply with the law process.

Results

In multivariable analysis, patients with self-determination were younger, were less likely to live in rural areas, were less likely to belong to the highest income quintile, were less likely to be treated in general hospitals, and were more likely to show a longer time from cancer diagnosis compared with patients with family determination. Compared with patients who did not comply with the law process, patients with self-determination were younger, lived in Seoul or capital area, were less likely to belong to the highest income quintile, were treated in general hospitals, were less likely to have genitourinary or hematologic malignancies, scored higher on the Charlson comorbidity index, and showed a longer time from cancer diagnosis. Patients with self-determination were more likely to use hospice and less likely to use intensive care units (ICUs) at the end-of-life (EOL).

Conclusion

Decedents with self-determination were more likely to be younger, reside in the Seoul or capital area, show a longer time from cancer diagnosis, and were less likely to belong to the highest income quintile. They utilized hospice more frequently, and received less ICU care at the EOL.

Preparation and Practice of the Necessary Documents in Hospital for the "Act on Decision of Life-Sustaining Treatment for Patients at the End-of-Life"

Purpose

Six forms relating to decisions on life-sustaining treatment (LST) for patients at the end-of-life (EOL) in hospital are required by the “Act on Decision of LST for Patients at the EOL.” We investigated the preparation and creation status of these documents from the database of the National Agency for Management of LST.

Materials and Methods

We analyzed the contents and details of each document necessary for decisions on LST, and the creation status of forms. We defined patients completing form 1 as “self-determined” of LST, and those whose family members had completed form 11/12 as “family decision” of LST. According to the determination subject, we compared the four items of LST on form 13 (the paper of implementation of LST) and the documentation time interval between forms.

Results

The six forms require information about the patient, doctor, specialized doctor, family members, institution, decision for LST, and intention to use hospice services. Of 44,381 who had completed at least one document, 36,693 patients had form 13. Among them, 11,531, 10,976, and 12,551 people completed forms 1, 11, and 12, respectively. The documentation time interval from forms 1, 11, or 12 to form 13 was 8.6±13.6 days, 1.0±9.5 days, and 1.5±9.7 days, respectively.

Conclusion

The self-determination rate of LST was 31% and the mean time interval from self-determination to implementation of LST was 8.6 days. The creation of these forms still takes place when the patients are close to death.

The Situation of Life-Sustaining Treatment One Year After Enforcement of the Act on Decisions on Life-Sustaining Treatment for Patients at the End-of-Life in Korea: Data of National Agency for Management of Life-Sustaining Treatment

Purpose

The “Act on Hospice and Palliative Care and Decisions on Life-Sustaining Treatment for Patients at the End-of-Life” was enacted on February 3, 2016 and went into effect on February 4, 2018 in Korea. This study reviewed the first year of determination to life-sustaining treatment (LST) through data analysis of the National Agency for Management of Life-Sustaining Treatment.

Materials and Methods

The National Agency for Management of LST provided data between February 4, 2018 and January 31, 2019 anonymously from 33,549 patients. According to the forms patients were defined as either elf-determinants or family-determinants.

Results

The median age of the patient was 73 and the majority was male (59.9%). Cancer patients were 59% and self-determinants were 32.1%. Cancer patients had a higher rate of self-determinants than non-cancer (47.3% vs. 10.1%). Plan for hospice service was high in cancer patients among self-determinants (81.0% vs. 37.5%, p < 0.001). In comparison to family-determinants, self-determinants were younger (median age, 67 years vs. 75 years; p < 0.001) and had more cancer diagnosis (87.1% vs. 45.9%, p < 0.001). Decision of withholding or withdrawing of LSTs in cancer patients was higher than non-cancer patients in four items.

Conclusion

Cancer patients had a higher rate in self-determination and withholding or withdrawing of LSTs than non-cancer patients. Continued revision of the law and education of the public will be able to promote withdrawing or withholding the futile LSTs in patients at end-of-life. Further study following the revision of the law should be evaluated to change of end-of-life care.

Family Members' Knowledge and Attitude Toward Life-Sustaining Treatment Decisions for Patients in the Intensive Care Unit

The decision to withhold or withdraw life-sustaining treatment (LST) lies sometimes in the hands of intensive care unit patients' families. Since 2018, family members of dying patients in South Korea have had the legal right to make decisions for the patients. This study aimed to examine knowledge and attitude toward LST among the family members of patients under intensive care since the foundation of the new legislation. Their perceptions of the roles of nurses were also explored. In this cross-sectional study, 89 participants completed survey questionnaires on demographic characteristics, relationship to patient, reason for admission, length of stay, awareness of the new legislation, knowledge and attitude toward LST, and perception of the role of nurses. The results indicated that knowledge was significantly associated with attitude and was, in fact, the only predictor of attitude toward LST (P = .021). Explaining the disease and prognosis in detail and relieving patients of their physical pain were the roles of nurses most valued by family members. The findings suggest that it is crucial for nurses to support family members and provide information about critical changes and medical options for collaborative decision making according to the patients' wishes during the dying process.

Changes in decision-making process for life-sustaining treatment in patients with advanced cancer after the life-sustaining treatment decisions-making act

Background

Cancer is a leading cause of death in Korea. To protect the autonomy and dignity of terminally ill patients, the Life-Sustaining Treatment Decision-Making Act (LST-Act) came into full effect in Korea in February 2018. However, it is unclear whether the LST-Act influences decision- making process for life-sustaining treatment (LST) for terminally ill cancer patients.

Methods

This was a retrospective study conducted with a medical record review of cancer patients who died at Ulsan University Hospital between July 2015 and May 2020. Patients were divided into two groups: those who died in the period before the implementation of the LST-Act (from July 2015 to October 2017, Group 1) and after the implementation of the LST-Act (from February 2018 to May 2020, Group 2). We measured the self-determination rate and the timing of documentation of do-not-resuscitate (DNR) or Physician Orders for Life-Sustaining Treatment (POLST) in both groups.

Results

A total of 1,834 patients were included in the analysis (Group 1, n = 943; Group 2, n = 891). Documentation of DNR or POLST was completed by patients themselves in 1.5 and 63.5 % of patients in Groups 1 and 2, respectively (p < 0.001). The mean number of days between documentation of POLST or DNR and death was higher in Group 2 than in Group 1 (21.2 days vs. 14.4 days, p = 0.001). The rate of late decision, defined as documentation of DNR or POLST within 7 days prior to death, decreased significantly in Group 2 (56.1 % vs. 47.6 %, p < 0.001). In the multivariable analysis, female patients (odds ratio [OR] 0.71, p = 0.002) and patients with more than 12 years of education (OR 0.70, p = 0.019) were significantly related to a reduced rate of late decision. More than 12 years of education (OR 0.53, p = 0.018) and referral to hospice palliative care (OR 0.40, p < 0.001) were significantly related to self-determination. Enforcement of LST-Act was related to a reduced rate of surrogate decision-making (OR 0.01, p < 0.001) and late decision (OR 0.51, p < 0.001). However, physicians with clinical experience of less than 3 years had a higher rate of surrogate decision-making (OR 5.08, p = 0.030) and late decision (OR 2.47, p = 0.021).

Conclusions

After the implementation of the LST-Act, the rate of self-determination increased and decisions for LST occurred earlier than in the era before the implementation of the LST-Act.

Analysis of Cancer Patient Decision-making and Health Service Utilization after Enforcement of the Life-Sustaining Treatment Decision-Making Act in Korea

Purpose

This study aimed to confirm the decision-making patterns for life-sustaining treatment (LST) and analyze medical service utilization changes after enforcement of the Life-Sustaining Treatment Decision-Making Act.

Materials and Methods

Of 1,237 patients who completed legal forms for life-sustaining treatment (hereafter called the LST form) at three academic hospitals and died at the same institutions, 1,018 cancer patients were included. Medical service utilization and costs were analyzed using claims data.

Results

The median time to death from completion of the LST form was three days (range, 0 to 248 days). Of these, 517 people died within two days of completing the document, and 36.1% of all patients prepared the LST form themselves. The frequency of use of the intensive care unit, continuous renal replacement therapy, and mechanical ventilation was significantly higher when the families filled out the form without knowing the patient’s intention. In the top 10% of the medical expense groups, the decision-makers for LST were family members rather than patients (28% patients vs. 32% family members who knew and 40% family members who did not know the patient’s intention).

Conclusion

The cancer patient’s own decision-making rather than the family’s decision was associated with earlier decision-making, less use of some critical treatments (except chemotherapy) and expensive evaluations, and a trend toward lower medical costs.

Type of bystander and rate of cardiopulmonary resuscitation in nursing home patients suffering out-of-hospital cardiac arrest

AIM

We investigated bystander cardiopulmonary resuscitation (CPR) provision rate and survival outcomes of out-of-hospital cardiac arrest (OHCA) patients in nursing homes by bystander type.

METHODS

A population-based observational study was conducted for nursing home OHCAs during 2013-2018. The exposure was the bystander type: medical staff, non-medical staff, or family. The primary outcome was bystander CPR provision rate; the secondary outcomes were prehospital return of spontaneous circulation (ROSC) and survival to discharge. Multivariable logistic regression analysis which corrected for various demographic and clinical characteristics evaluated bystander type impact on study outcomes. Bystander CPR rate trend was investigated by bystander type.

RESULTS

Of 8281 eligible OHCA patients, 26.0%, 70.8%, and 3.2% cases were detected by medical staff, non-medical staff, and family, respectively. Provision rate of bystander CPR was 69.9% and rate of bystander defibrillation was 0.4% in total. Bystander CPR was provided by medical staff, non-medical staff, and families in 74.8%, 68.9%, and 52.1% respectively. Total survival rate was 2.2%, out of which, 3.3% was for medical staff, 3.2% for non-medical staff, and 0.6% for family. Compared to the results of detection by medical staff, the adjusted odds ratios (95% CIs) for provision of bystander CPR were 0.56 (0.49-0.63) for detection by non-medical staff and 0.33 (0.25-0.44) for detection by family. The bystander CPR rates of all three groups increased over time, and among them, the medical staff group increased the most. For prehospital ROSC and survival to discharge, no significant differences were observed according to bystander type.

CONCLUSION

Although OHCA was detected more often by non-medical staff, they provided bystander CPR less frequently than the medical staff did. To improve survival outcome of nursing home OHCA, bundle interventions including increasing the usage of automated external defibrillators and expanding CPR training for non-medical staff in nursing home are needed.

A National Study of Life-Sustaining Treatments in South Korea: What Factors Affect Decision-Making?

PURPOSE

This cross-sectional study investigated the status of life-sustaining treatment (LST) practices and identified characteristics and factors influencing decision-making practices.

Materials and Methods

The National Agency for Management of Life-sustaining Treatment retains records provided by doctors regarding patients subject to LST implementation. A total of 71,327 patients receiving LST were identified. We analyzed all nationally reported data between February 2018 and October 2019. Indicators such as the proportion of deaths, records for decision to terminate LST, implementation of LST records, and registration of Advance Statements on LST were analyzed.

RESULTS

A total of 67,252 (94.3%) end-of life decisions were implemented in South Korea. The proportion of deaths preceded by a LST plan, non-self-determination LST decision, and any advance statements was 33.5% (23,891/71,327), 66.5% (47,436/71,327), and 1.2% (890/71,327), respectively. The logistic regression model revealed that self-determination to terminate LST was more frequent for men than for women and higher for those aged 30-69. Disability (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.56 to 0.61), living in non-metropolitan areas (OR, 0.84; 95% CI, 0.81 to 0.86), and disease comorbidity was independently associated with a low level of self-determination.

CONCLUSION

After the implementation of the new LST Act, about a third of patients in end-of-life process made decisions regarding their medical LST. However, family members still play a major role in LST decisions where the patient's intention cannot be verified. Decisions related to LST are predominantly made when death is imminent. Thus, it is necessary to increase awareness of end-of-life LST decision-making among medical staff and the public.

Difficulties Doctors Experience during Life-Sustaining Treatment Discussion after Enactment of the Life-Sustaining Treatment Decisions Act: A Cross-Sectional Study

Purpose

This study aimed to investigate difficulties doctors experience during life-sustaining treatment (LST) discussion with seriously ill patients and their families after enactment of the LST Decisions Act in February 2018.

Materials and Methods

A cross-sectional survey was conducted in a tertiary hospital in the Republic of Korea in August 2019. Six hundred eighty-six doctors who care for seriously ill patients were given a structured questionnaire, and difficulties during the discussion were examined.

Results

One hundred thirty-two doctors completed the questionnaire. Eighty-five percent answered they treat cancer patients. Most (86.4%) experienced considerable difficulties during LST discussions (mean score, 7.4±1.6/10). The two most common difficulties were communication with patients and family and determining when to discuss LST. Two-thirds of doctors found direct discussions with the patient difficult and said they would initiate LST discussions only with family. LST discussions were actually initiated later than considered appropriate. When medically assessing whether the patient is imminently dying, 56% of doctors experienced disagreements with other doctors, which could affect their decisions.

Conclusion

This study found that most doctors experienced serious difficulties regarding communication with patients and family and medical assessment of dying process during LST discussions. To alleviate these difficulties, further institutional support is needed to improve the LST discussion between doctors, patients, and family.
