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.

Attitudes toward Social Issues Related to Opioid Use among Palliative Care Physicians.

Purpose: This study investigated palliative care physicians' attitudes regarding social issues related to opioid use. Methods: An email survey was sent to 674 physicians who were members of the Korean Society for Hospice and Palliative Care (KSHPC). Results: Data from 66 physicians were analyzed (response rate, 9.8%). About 70% of participants stated that their prescribing patterns were not influenced by social issues related to opioid use, and 90% of participants thought that additional regulations should be limited to non-cancer pain. Under the current circumstances, pain education for physicians is urgently needed, as well as increased awareness among the public. Half of the respondents identified the KSHPC as the primary organization responsible for providing pain education. Conclusion: Palliative care physicians' prescribing patterns were not influenced by social issues related to opioid use, and these issues also should not affect cancer pain control.

Association of Body Mass Index and Waist Circumference with Osteoarthritis among Korean Adults: A Nationwide Study.

BACKGROUND: Evidence on the association between obesity parameters, including body mass index (BMI) and waist circumference (WC), and osteoarthritis is limited. This study aimed to investigate these associations in Korean adults. METHODS: This nationwide cross-sectional study used data from 24,101 adults aged ≥19 years who participated in the Korea National Health and Nutrition Examination Survey 2016-2020. Odds ratios (ORs) and 95% confidence intervals (CIs) for osteoarthritis according to BMI and WC were analyzed using multivariable logistic regression analyses. RESULTS: The prevalence of osteoarthritis was higher in individuals with general (10.0%) and abdominal obesity (12.8%) compared with those without. Greater BMI and WC were associated with a higher prevalence (P<0.001) and risk of osteoarthritis (Model 3, P for trend <0.001). Individuals with general and abdominal obesity were associated with a 1.50-fold (OR, 1.50; 95% CI, 1.35-1.67) and 1.64-fold (OR, 1.64; 95% CI, 1.47-1.84) increased risk of osteoarthritis, compared with those without. Similar associations were observed in subgroups according to age, sex, smoking status, and presence of diabetes mellitus. The odds of osteoarthritis 1.73-fold increased (OR, 1.73; 95% CI, 1.53-1.95) in individuals with both general and abdominal obesity compared with those without any of them. CONCLUSION: Greater BMI, WC, and general and abdominal obesity were associated with an increased risk of osteoarthritis in Korean adults. Appropriate management of abdominal and general obesity may be important to reduce the risk of osteoarthritis.

Association Between Oral Health Status and Survival Time in Terminally Ill Cancer Patients.

INTRODUCTION: Patients with terminal cancer often experience various oral problems. Whether oral health status is associated with the survival of terminally ill cancer patients receiving palliative care remains unclear. METHODS: We analyzed the data of 59 Korean patients with terminal cancer receiving palliative care, including their oral health status, using a modified Korean version of the Oral Health Assessment Tool (OHAT). Patients were categorized into "Good," "Moderate," or "Poor" groups based on OHAT scores. The Kaplan-Meier method was used to compare the median survival time, and the prognosis between groups was estimated using Cox proportional hazard models. RESULTS: The most common oral symptoms observed were xerostomia (69.5%) and mucositis (17.0%). Significantly shorter survival times were observed in patients with hyperbilirubinemia, elevated creatinine levels, and no use of dentures. The "Poor" group had a shorter survival than the "Good" oral group (P = .010). A multivariate Cox proportional hazards analysis revealed that the "Poor" group was significantly associated with poor survival compared to the "Good" group (hazard ratio, 2.05; P = .047). CONCLUSION: Terminally ill cancer patients with poor oral health may have a higher risk of shorter survival. Palliative care professionals should pay attention to oral health. Further research is needed to determine the effects of oral care on survival.

Public awareness of advance care planning and hospice palliative care: a nationwide cross-sectional study in Korea.

CONTEXT: Advance care planning (ACP) and hospice palliative care (HPC) have potential benefits for individuals and health systems. Public awareness of them might increase their acceptance. OBJECTIVES: To examine public awareness of ACP and HPC and related factors including individuals' experience of health care among Korean population. METHODS: A cross-sectional study based on a nationally representative sample was conducted. Data from participants aged 15 years or older were examined. Socio-demographic characteristics, health-related factors, health care experience in the past year, and awareness of ACP and HPC were analyzed. Subgroup analysis was conducted to determine associations between specific experiences during outpatient visit and awareness of ACP and HPC. RESULTS: Of a total of 13,546 subjects, 39.3% and 35.7% reported awareness of ACP and HPC, respectively. About half (48.6%) of participants reported that they were completely unaware of ACP or HPC. Recent outpatient visit was positively associated with HPC awareness. Participants were more likely to recognize ACP or HPC if they had experience in hospitalization and health checkup over the past year and had trust in the medical system. Conversely, participants who had inadequate health care access due to cost burden showed low awareness of ACP and HPC. CONCLUSION: There was a lack of public awareness of ACP and HPC. There were significant differences depending on various factors, especially individual health care experiences. Appropriate interventions are needed to facilitate discussion of ACP and HPC, thereby increasing public awareness.

Low Serum Creatinine as Well as High Serum Creatinine Is Associated with Prognosis of Patients with Cancer in End-of-Life.

Background: The prognosis of end-of-life patients is challenging, and clinicians have attempted to predict survival more accurately. High serum creatinine (sCr) levels are associated with lower survival rates in patients with various cancers; however, low sCr levels are commonly expected in patients with terminal cancer because of muscle wasting and malnutrition. Therefore, we investigated the prevalence of low and high sCr levels and their association with survival duration in patients with terminal cancer in a palliative care unit. Methods: We analyzed the medical records of 280 patients admitted to a palliative care unit. Patients were divided into low (<0.5 mg/dL), normal (0.5-1.2 mg/dL), and high (>1.2 mg/dL) sCr groups. Kaplan-Meier survival curves using sCr levels were plotted and compared using the log-rank test. Using stepwise selection, a multivariable Cox proportional hazards model was used to identify the significant prognostic factors. Results: The median survival durations in the high-, low-, and normal-sCr groups were 9.57 days, 22.26 days, and 27.51 days, respectively. Multivariable Cox proportional hazard model identified that males (hazard ratio [HR], 1.81; 95% confidence interval [CI], 1.16-2.85), poor performance status (HR, 3.43; 95% CI, 1.12-10.54), total parenteral nutrition use (HR, 1.84; 95% CI, 1.09-3.1), high sCr (HR, 2.74; 95% CI, 1.52-4.94), and low sCr (HR, 1.22; 95% CI, 1.07-1.43) were significantly associated with a shorter survival time. Conclusion: Low and high serum creatinine levels were significantly associated with poor survival in patients with cancer at the end-of-life stage. Therefore, readily available and simple biomarkers may help plan advanced care in palliative care settings.

Analysis of the Time Interval between the Physician Order for Life-Sustaining Treatment Completion and Death.

BACKGROUND: This study aimed to explore the time interval distribution pattern between the Physicians Order for Life-Sustaining Treatment (POLST) form completion and death at a tertiary hospital in South Korea. It also examined the association between various independent parameters and POLST form completion timing. METHODS: A total of 150 critically ill patients admitted to Korea University Guro Hospital between June 1, 2018 and December 31, 2018 who completed the POLST form were retrospectively analyzed and included in this study. Data were analyzed with descriptive statistics, and group comparisons were performed using the chi-square test for categorical variables. Fisher's exact test was also used to compare cancer versus non-cancer groups. RESULTS: More than half the decedents (54.7%) completed their POLST within 15 days of death and 73.4% within 30 days. The non-cancer group had the highest percentage of patients (77.8%) who died within 15 days of POLST form completion while the colorectal (39.1%) and other cancer (37.5%) groups had the lowest (P=0.336). CONCLUSION: Our findings demonstrated a current need for more explicit guidance to assist physicians with initiating more timely, proactive end-of-life discussions.

Completion rate of physician orders for life-sustaining treatment for patients with metastatic or recurrent cancer: a preliminary, cross-sectional study.

BACKGROUND: "End of life" is a difficult topic of conversation in East Asian cultures, even among patients and doctors who share a good rapport. In 2016, the Hospice, Palliative Care, and Life-Sustaining Treatment Decision-Making Act, which took the form of "Physician Orders for Life-Sustaining Treatment," was introduced in South Korea. This study was conducted to investigate the completion rate of Physician Orders for Life-Sustaining Treatment in patients with advanced cancer on the active recommendation of physicians, as well as patients' general attitudes toward end-of-life care. METHODS: We conducted a preliminary, cross-sectional descriptive survey on patients with advanced cancer. A total of 101 patients with advanced solid cancer agreed to participate in the study. The primary endpoint was the rate of completion of Physician Orders for Life-Sustaining Treatment based on a doctor's suggestion. Written interviews were conducted to understand the perceptions and factors influencing patients' decisions. RESULTS: Of the 101 patients, 72 (71.3%) agreed to prepare Physician Orders for Life-Sustaining Treatment. Patients who had an educational level of high school or higher were more likely to agree to complete Physician Orders for Life-Sustaining Treatment documentation as compared to the lower educational status group. More than half of the respondents who completed Physician Orders for Life-Sustaining Treatment documentation reported that they had more than a fair understanding of "life-sustaining care" or "Physician Orders for Life-Sustaining Treatment." Participants' reasons for Physician Orders for Life-Sustaining Treatment completion were diverse. CONCLUSIONS: We found that highly educated patients, who understood the concept behind the policy well, tended to accept Physician Orders for Life-Sustaining Treatment without hesitation. Better education, information shared through the media, and conversations with health care providers might improve understanding of Physician Orders for Life-Sustaining Treatment in patients with cancer.

Yeast (1 → 3)-(1 → 6)-ß-d-glucan alleviates immunosuppression in gemcitabine-treated mice.

Gemcitabine (2'-deoxy-2',2'-difluorocytidine, dFdC) is one of the most effective chemotherapy drugs commonly used for treatment of various tumors. Despite its significant anticancer effects, some adverse effects create obstacles to treatment. The main toxicity of gemcitabine is myelosuppression, which not only reduces patient quality of life, but also hinders further anticancer treatment. In this respect, immunotherapy can address these drawbacks because of its ability to enhance the patient's immune system. To improve immune system function, yeast-derived ß-glucans, which are well-known biologic response modifiers, were administered to gemcitabine-treated mice. The in vivo experiment revealed that orally administered yeast (1 → 3)-(1 → 6)-ß-d-glucan effectively alleviated myelosuppression associated with gemcitabine-induced pancytopenia. Moreover, analysis of myelopoiesis-related cytokine expression through real-time PCR demonstrated that ß-glucan treatment significantly upregulated hematopoietic responses in gemcitabine-treated mice. Furthermore, orally administered ß-glucan significantly induced the expression of IFN-γ and IL-2 in splenocytes of gemcitabine-treated mice. It also restored the cytotoxicity of splenocytes against YAC-1 in gemcitabine-treated mice and displayed a positive effect on gemcitabine-damaged bone marrow tissue. In conclusion, yeast ß-glucans have the potential to be used as adjuvants for alleviating chemotherapy-induced immunosuppression in patients.

Obesity, abdominal obesity and subsequent risk of kidney cancer: a cohort study of 23.3 million East Asians.

BACKGROUND: Limited evidence exists regarding associations between obesity and kidney cancer among Asians. We examined the associations between obesity measures and risk of kidney cancer. METHODS: We included 23,313,046 adults who underwent health examinations provided by the Korean National Health Insurance Service 2009-2012 and performed multivariable Cox proportional hazards regression analyses. RESULTS: During 5.4 years of follow-up, 18,036 cases of kidney cancer were recorded, and cumulative incidence was 0.12%. General and abdominal obesity were associated with 1.32-fold increased risk of kidney cancer compared with groups without either obesity status. Underweight individuals showed decreased adjusted hazard ratio (HR) for kidney cancer (0.76, 95% confidence interval: 0.68-0.85) compared to those with normal body mass index (BMI), while the HRs increased among individuals with BMI 23-24.9 kg/m2 (1.23, 1.18-1.28), 25-29.9 kg/m2 (1.41, 1.36-1.46) and ≥30 kg/m2 (1.77, 1.65-1.90) (P for trend < 0.001). HRs of kidney cancer increased with increasing waist circumference (WC) (P for trend < 0.001). Compared to non-obese condition, the coexistence of general and abdominal obesity increased the HR (1.45, 1.40-1.50). CONCLUSIONS: This study demonstrated positive associations of BMI and WC with kidney cancer risk. General and abdominal obesity may be risk factors of kidney cancer.

Antioxidative and anti-inflammatory effect of Phellinus igniarius on RAW 264.7 macrophage cells.

This study investigated the antioxidative and anti-inflammatory effect of Phellinus igniarius (PI) on RAW264.7 mouse macrophages. Cell viability was determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Measurement of nitric oxide (NO) synthesis was performed using the NO detection. To identify mRNA expressions of cyclooxygenase-2 (COX-2), inducible NO synthase (iNOS), interleukin (IL)-1α, IL-1ß, IL-6, and tumor necrosis factor (TNF)-α, real time polymerase chain reaction (PCR) was performed. Assessment of prostaglandin E2 (PGE2) synthesis was performed using the PGE2 immunoassay. Measurement of free radical scavenging activity was performed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The MTT assay revealed that PI exerted no significant cytotoxicity in the RAW 264.7 macrophage cells. From the PGE2 immunoassay and NO detection, PGE2 and NO synthesis were significantly suppressed in the PI treated groups compared to the lipopolysaccharide (LPS) treated groups. Real-time PCR analysis revealed that the mRNA expression of COX-2, iNOS, IL-1α, IL-1ß, IL-5, and TNF-α were significantly decreased in the PI treated groups compared to the LPS treated groups. And, PI showed dose-dependent increase in the DPPH radical scavenging activity. In conclusion, PI maybe offer a valuable mode of therapy for the treatment of inflammatory diseases.

Impact of body mass index and body weight variabilities on mortality: a nationwide cohort study.

BACKGROUND/OBJECTIVES: There is limited information regarding the impact of body mass index (BMI) and body weight (BWt) variabilities on mortality. This study aimed to investigate the association between BMI, BWt variabilities and subsequent mortality in the Korean population. SUBJECTS/METHODS: This study used a representative sample cohort enrolled in the national health examination program conducted by the Korean National Health Insurance Service, and 125,391 individuals were included and followed up until 2013 (mean follow-up period = 84 months). BMI and BWt variabilities were estimated as the standard deviation (SD) and coefficient of variation (CV) of serial measurements of BMI and BWt (BMI_SD, BWt_SD, BMI_CV, and BWt_CV). Cox proportional hazard regression models were used to evaluate the all-cause and cause-specific mortality according to variability indices. RESULTS: Baseline BMI showed a non-linear association with all-cause mortality. The highest quartile (Q4) groups of variability indices were associated with increased all-cause mortality risk compared to the lowest quartile (Q1) groups after adjusting for confounding factors (hazard ratio [95% confidence interval] = 1.23 [1.11-1.37] for BMI_SD; 1.25 [1.06-1.47] for BMI_CV; 1.33 [1.20-1.48] for BWt_SD; 1.42 [1.28-1.58] for BWt_CV). The hazard ratios of all-cause mortality increased from the Q2 to the Q4 groups of variability indices, in each sex group and among individuals aged ≥40 years. Furthermore, Q4 groups of variability indices were positively associated with cause-specific mortality compared to groups with Q1-Q3 of the indices (1.28 [1.05-1.56] for BWt_SD, 1.21 [1.001-1.47] for BMI_CV, 1.29 [1.06-1.56] for BWt_CV regarding cardiovascular diseases mortality; 1.18 [1.03-1.36] for BWt_SD, 1.21 [1.06-1.39] for BMI_CV, 1.26 [1.10-1.44] for BWt_CV regarding cancer mortality). CONCLUSIONS: Our results suggest that BMI and BWt variabilities are independent risk factors for all-cause and cause-specific mortality.

The impact of caregiver's role preference on decisional conflicts and psychiatric distresses in decision making to help caregiver's disclosure of terminal disease status.

PURPOSE: The objective of this study was to investigate the impact of caregivers' role preference in decision making on conflicts and psychiatric distresses. METHODS: The responses of 406 caregivers of terminal cancer patients enrolled in a trial determining the efficacy of a decision aid focused on the disclosure of terminal disease status were included in this secondary analysis. The outcomes include the change scores of the Decision Conflict Scale (DCS) and depression and anxiety subscales of the Hospital Anxiety and Depression Scale (HADS) at the 1 and 3 months from baseline. The linear mixed model was employed to discover the impact of caregivers' decisional role preference on the outcomes. FINDINGS: Of the 406, 137 (33.7%) showed an active role preference and 269 (66.3%) showed a passive role preference. In the post hoc analysis of the adjusted differences of change scores between passive caregivers who received decision aid (passive-decision aid) and active caregivers with decision aid (active-decision aid), non-significant differences were observed in the DCS. However, at the 3-month, the change scores of the HADS depression subscale increased by 4.43 (effect size, 0.71) and those of the HADS anxiety subscale increased by 4.14 (effect size, 0.61) in the passive-decision aid group than in active-decision aid group, showing moderate to large difference. CONCLUSIONS: These findings suggest that information might be ethically recommended in a format that is interactive and tailored to how much an individual wishes to be involved in the decision-making process.

Practice Patterns in Distinguishing Between Background Pain and Breakthrough Pain During Patient Education: a Korean Physician Survey.

This study sought to explore the association between physician practice patterns and patient education, with a focus on breakthrough cancer pain (BTcP). A nationwide online survey was conducted by 92 Korean physicians. Thirteen questions on Korean physician's assessment, prescription, patient education practices, and knowledge regarding BTcP were administered. Based on their responses, physicians were divided using two methods: (1) by their patient education practices, where the "education group" always explained the distinction between background pain and BTcP and the "less education group" which explained it less frequently; and (2) by their definition of BTcP, as occurring "after control of background pain" or "regardless of background pain." We compared practice patterns using Fisher's exact test or Student's t test and performed multiple logistic regression analysis. The "education group" (65 physicians, 70.7 %) was more likely than the "less education group" to assess BTcP meticulously (odds ratio [OR] 17.13, 95 % confidence interval [CI] 4.98-58.94), prepare rescue medications in advance (OR 3.67, 95 % CI 1.36-9.90), and give explicit instructions regarding medications (OR 36.68, 95 % CI 5.63-239.15). Physicians who defined BTcP as occurring "after control of background pain" were more likely to explain how to take rescue medication (P < 0.05) than physicians who defined BTcP as occurring "regardless of background pain." Korean physicians' BTcP practice patterns may be affected by whether they consistently educate patients on the distinction between background pain and BTcP, regardless of their knowledge of the definition of BTcP.

Factors Associated With Caregivers' Resilience in a Terminal Cancer Care Setting.

BACKGROUND: Resilience implies characteristics such as self-efficacy, adaptability to change, optimism, and the ability to recover from traumatic stress. Studies on resilience in family caregivers (FCs) of patients with terminal cancer are rare. This study aims to examine the factors associated with FCs' resilience in a terminal cancer care setting. METHODS: This is a cross-sectional study of 273 FCs from 7 hospice and palliative care units in Korea. Resilience was categorized as high and low, and factors associated with resilience were grouped or categorized into subscales. A multivariate logistic regression analysis was used to examine relevant factors. RESULTS: High FCs' resilience was significantly associated with FCs' health status, depression, and social support. In a multivariate regression model, FCs' perception of good health (adjusted odds ratio [aOR] = 2.26, 95% confidence interval [CI] = 1.16-4.40), positive social support (aOR = 3.70, 95% CI = 1.07-12.87), and absence of depression (aOR = 3.12, 95% CI = 1.59-6.13) remained significantly associated with high FCs' resilience. CONCLUSION: Lack of family support is associated with and may be a cause of diminished resilience. And more concern should be paid to FCs to improve FCs' health and emotional status. Education programs might be effective for improving caregivers' resilience. Further research with supportive interventions is indicated.

Validation of the Korean Version of the Breakthrough Pain Assessment Tool in Cancer Patients.

CONTEXT: Breakthrough cancer pain has not been properly evaluated and treated because there are relatively few available measurements. The Breakthrough Pain Assessment Tool (BAT) is currently recognized as a brief, multidimensional, and reliable measurement. OBJECTIVES: The objective of this study was to validate the Korean version of the BAT (BAT-K) in adult cancer patients. METHODS: We conducted a forward-backward translation and cross-cultural equivalence test. The psychometric properties with 120 cancer patients were assessed using factor analysis, reliability, and validity. RESULTS: The Korean translation was well accepted by participants. Factor analysis revealed the presence of two underlying factors: frequency/severity and duration/medication efficacy. Cronbach alpha coefficient was 0.743. Severity, distress, and disruption of normal life showed strong reliability. The intraclass correlation for the test-retest reliability was 0.782 (95% confidence interval 0.694-0.854). The BAT-K had significant correlations with the Brief Pain Inventory, Pain Management Index, and Eastern Cooperative Oncology Group performance status (all P values < 0.05). CONCLUSION: The BAT-K is a valid and reliable measurement of breakthrough cancer pain in Korean cancer patients.

Effects of hospital palliative care on health, length of stay, and in-hospital mortality across intensive and non-intensive-care units: A systematic review and metaanalysis.

OBJECTIVE: Hospital palliative care has been shown to improve quality of life and optimize hospital utilization for seriously ill patients who need intensive care. The present review examined whether hospital palliative care in intensive care (ICU) and non-ICU settings will influence hospital length of stay and in-hospital mortality. METHOD: A systematic search of CINAHL/EBSCO, the Cochrane Library, Google Scholar, MEDLINE/Ovid, PubMed, and the Web of Science through 12 October 2016 identified 16 studies that examined the effects of hospital palliative care and reported on hospital length of stay and in-hospital death. Random-effects pooled odds ratios and mean differences with corresponding 95% confidence intervals were estimated. Heterogeneity was measured by the I 2 test. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was utilized to assess the overall quality of the evidence. RESULTS: Of the reviewed 932 articles found in our search, we reviewed the full text of 76 eligible articles and excluded 60 of those, which resulted in a final total of 16 studies for analysis. Five studies were duplicated with regard to outcomes. A total of 18,330 and 9,452 patients were analyzed for hospital length of stay and in-hospital mortality from 11 and 10 studies, respectively. Hospital palliative care increased mean hospital length of stay by 0.19 days (pooled mean difference = 0.19; 95% confidence interval [CI 95%] = -2.22-2.61 days; p = 0.87; I 2 = 95.88%) and reduced in-hospital mortality by 34% (pooled odds ratio = 0.66; CI 95% = 0.52-0.84; p < 0.01; I 2 = 48.82%). The overall quality of evidence for both hospital length of stay and in-hospital mortality was rated as very low and low, respectively. SIGNIFICANCE OF RESULTS: Hospital palliative care was associated with a 34% reduction of in-hospital mortality but had no correlation with hospital length of stay.

Palliative care development in the Asia-Pacific region: an international survey from the Asia Pacific Hospice Palliative Care Network (APHN).

BACKGROUND: Although palliative care is an important public healthcare issue worldwide, the current situation in the Asia-Pacific region has not been systematically evaluated. OBJECTIVES: This survey aimed to clarify the current status of palliative care in the Asia-Pacific region. METHODS: Questionnaires were sent to a representative physician of each member country/region of the Asia Pacific Hospice Palliative Care Network (APHN). The questionnaire examined palliative care service provision, information regarding physician certification in palliative care, the availability of essential drugs for palliative care listed by the International Association for Hospice and Palliative Care (IAHPC) and the regulation of opioid-prescribing practice. RESULTS: Of the 14 member countries/regions of the APHN, 12 (86%) responded. Some form of specialist palliative care services had developed in all the responding countries/regions. Eight member countries/regions had physician certifications for palliative care. Most essential drugs for palliative care listed by the IAHPC were available, whereas hydromorphone, oxycodone and transmucosal fentanyl were unavailable in most countries/regions. Six member countries/regions required permission to prescribe and receive opioids. CONCLUSIONS: The development of palliative care is in different stages across the surveyed countries/regions in the Asia-Pacific region. Data from this survey can be used as baseline data for monitoring the development of palliative care in this region.
