Impact of family caregivers' awareness of the prognosis on their quality of life/depression and those of patients with advanced cancer: a prospective cohort study.

PURPOSE: A caregiver's prognostic awareness can affect clinical decisions for the patient. The purpose of this study was to examine the impact of family caregivers' prognostic awareness on the quality of life (QOL) and emotional state of both patients with advanced cancer and their caregivers. METHODS: This prospective cohort study was conducted from December of 2016 to January of 2018. A total of 159 patients with advanced cancer and an equal number of caregivers participated. The investigation tools used include the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C15-Palliative, the McGill Quality of Life Questionnaire, and the Patient Health Questionnaire-9, and evaluation was performed at baseline, 3 months, and 6 months. Covariance analysis with a general linear modeling was used to compare changes in quality of life scores according to the caregivers' awareness of the prognosis. RESULTS: Mean patient overall QOL score increased in the group of caregivers who were aware of prognosis and decreased in the caregivers who were not aware of the prognosis (p = 0.018). The changes over time in the patients' QOL scores associated with symptoms improved with caregiver awareness (pain, p = 0.017; dyspnea, p = 0.048; appetite loss, p = 0.045). The percentage of depressed patients was smaller after 3 months in the group with caregivers aware of the prognosis (baseline to 3 months p = 0.028). Caregivers who did not understand their patients' prognosis exhibited better existential well-being (p = 0.036), and the incidence of depression was lower in this group at 3 months (p = 0.024). CONCLUSION: Caregivers' prognostic awareness may improve the quality of life and mood in patients with advanced cancer; however, this awareness may harm the quality of life and mood of the caregivers. These results may aid in developing in-depth interventions regarding prognosis for both patients and their caregivers.

Association of illness understanding with advance care planning and end-of-life care preferences for advanced cancer patients and their family members.

PURPOSE: Little has been determined regarding the association between patients' and families' illness understanding and preferences for medical care. We aimed to evaluate the association of illness understanding with advance care planning (ACP) and preferences for end-of-life care, such as aggressive care, early palliative care (EPC), and hospice care, among advanced cancer patients and their family caregivers. METHODS: Patients were recruited for a prospective cohort study at outpatient and inpatient facilities in nine university hospitals in Korea (n = 150), and their primary family caregivers were also asked to participate (n = 101). Data on ACP and end-of-life care preferences were collected only at baseline in the cohort study with optional questions and were used to analyze these study results. RESULTS: Patients with illness understanding were more likely to have documented physician orders for life-sustaining treatment (POLSTs) (adjusted odds ratio [aOR] of 4.94) and to have discussed ACP with their families (aOR 2.15) than those who did not. Being expected to live for several months, they were unlikely to prefer active treatment. Caregivers understanding patients' illness were more likely to write advance directives (ADs) and to discuss ACP; furthermore, they had already discussed ACP with family members. They did not prefer active treatment or life-sustaining treatments when their family members were expected to die within a few weeks. There was no significant association between illness understanding and preferences for EPC. CONCLUSION: Accurately recognizing an incurable disease is associated with preferences for more ACP and less aggressive care but not with preferences for EPC or hospice care among both advanced cancer patients and their family caregivers.

Correction to: Priorities of a "good death" according to cancer patients, their family caregivers, physicians, and the general population: a nationwide survey.

While recently extending that research, however, we discovered that 236 members of the general population were mistakenly duplicated by the investigating agency (Word Research) and 1241 were reported rather than 1005. Here, we present corrections and discuss the relevant data.

Priorities of a "good death" according to cancer patients, their family caregivers, physicians, and the general population: a nationwide survey.

PURPOSE: Understanding the concept of a "good death" is crucial to end-of-life care, but our current understanding of what constitutes a good death is insufficient. Here, we investigated the components of a good death that are important to the general population, cancer patients, their families, and physicians. METHODS: We conducted a stratified nationwide cross-sectional survey of cancer patients and their families from 12 hospitals, physicians from 12 hospitals and the Korean Medical Association, and the general population, investigating their attitudes toward 10 good-death components. FINDINGS: Three components-"not be a burden to the family," "presence of family," and "resolve unfinished business"-were considered the most important components by more than 2/3 of each of the three groups, and an additional three components-"freedom from pain," "feel that life was meaningful," and "at peace with God"-were considered important by all but the physicians group. Physicians considered "feel life was meaningful," "presence of family," and "not be a burden to family" as the core components of a good death, with "freedom from pain" as an additional component. "Treatment choices' followed, "finances in order," "mentally aware," and "die at home" were found to be the least important components among all four groups. CONCLUSION: While families strongly agreed that "presence of family" and "not be a burden to family" were important to a good death, the importance of other factors differed between the groups. Health care providers should attempt to discern each patient's view of a good death.

Development and validation of the quality care questionnaire -palliative care (QCQ-PC): patient-reported assessment of quality of palliative care.

BACKGROUND: In this study, we aimed to develop and validate an instrument that could be used by patients with cancer to evaluate their quality of palliative care. METHODS: Development of the questionnaire followed the four-phase process: item generation and reduction, construction, pilot testing, and field testing. Based on the literature, we constructed a list of items for the quality of palliative care from 104 quality care issues divided into 14 subscales. We constructed scales of 43 items that only the cancer patients were asked to answer. Using relevance and feasibility criteria and pilot testing, we developed a 44-item questionnaire. To assess the sensitivity and validity of the questionnaire, we recruited 220 patients over 18 years of age from three Korean hospitals. RESULTS: Factor analysis of the data and fit statistics process resulted in the 4-factor, 32-item Quality Care Questionnaire-Palliative Care (QCQ-PC), which covers appropriate communication with health care professionals (ten items), discussing value of life and goals of care (nine items), support and counseling for needs of holistic care (seven items), and accessibility and sustainability of care (six items). All subscales and total scores showed a high internal consistency (Cronbach alpha range, 0.89 to 0.97). Multi-trait scaling analysis showed good convergent (0.568-0.995) and discriminant (0.472-0.869) validity. The correlation between the total and subscale scores of QCQ-PC and those of EORTC QLQ-C15-PAL, MQOL, SAT-SF, and DCS was obtained. CONCLUSION: This study demonstrates that the QCQ-PC can be adopted to assess the quality of care in patients with cancer.

Randomized Controlled Trial of Advance Care Planning Video Decision Aid for the General Population.

CONTEXT: Advance care planning (ACP) in a healthy general population could improve the quality of care when a health problem arises. OBJECTIVES: The purpose of this study was to evaluate the efficacy of video decision support aid in increasing the intention to document ACP in the general healthy population. METHODS: In this randomized controlled trial, we enrolled 250 members of the general population (aged 20 years and older and determined to be healthy), stratified by age and sex. The intervention was a video that provided information about ACP and end-of-life care options such as cardiopulmonary resuscitation (CPR) and palliative care. An attention-control arm was given a booklet about advance directives. Primary outcome was a change in intention to document ACP. Secondary outcomes included the intention to refuse CPR at terminal status, CPR and palliative care knowledge score, and the Hospital Anxiety and Depression Scale. RESULTS: About 250 participants were randomly assigned, half to the video-assisted intervention group and half to the attention-control group. Within one week postintervention, the intention to document ACP was significantly higher in the video-assisted intervention arm (68.0% vs. 39.2%; P < 0.001), and changes in the intention to document ACP were significantly greater in the video group than in the brochure group (P = 0.008; Δ = 14.4%). Palliative care knowledge score was also significantly increased in the video group (P = 0.036). CONCLUSION: A well-constructed video decision support intervention can increase the intention to document ACP in the general population that presumably had little opportunity to discuss ACP with physicians.

The Impacts of Prognostic Awareness on Mood and Quality of Life Among Patients With Advanced Cancer.

BACKGROUND: Accurate awareness of the prognosis is an important factor in the treatment decision of patients with advanced cancer; however, prognostic disclosure is still subject to debate because it can reduce patient's satisfaction and increase depression. AIM: The purpose of this study is to assess whether patients' prognostic awareness is associated with decreased quality of life (QoL) or increased depressive mood in patients with advanced cancer. DESIGN AND PARTICIPANTS: In this cohort study, 386 patients with advanced cancer were recruited across 3 periods from December 2016 to August 2018. The outcome of this study was a change in QoL and depression according to the patients' prognostic awareness at baseline, 3 months, and 6 months. RESULTS: This study found significant differences in changes of QoL based on patients' prognostic awareness. From baseline to 3 months, emotional functioning (P = .039), pain (P = .042), existential well-being (P = .025), and social support (P = .038) subscale scores improved significantly more in those with lack of prognostic awareness. Over 6 months, the group without prognostic awareness improved significantly in terms of physical functioning (P = .037), emotional functioning (P = .002), nausea/vomiting (P = .048), and constipation (P = .039) subscale scores and existential well-being scores (P = .025). No significant difference between the groups was found in terms of depression. CONCLUSION: Accurate prognostic awareness may pose harm and may provide no additional benefits in terms of QoL and mood among patients with advanced cancer for a short period of time.

Efficacy of a Decision Aid Consisting of a Video and Booklet on Advance Care Planning for Advanced Cancer Patients: Randomized Controlled Trial.

CONTEXT: Few randomized controlled trials of advance care planning (ACP) with a decision aid (DA) show an effect on patient preferences for end-of-life (EOL) care over time, especially in racial/ethnic settings outside the U.S. OBJECTIVES: The objective of this study was to examine the effect of a decision aid consisting of a video and an ACP booklet for EOL care preferences among patients with advanced cancer. METHODS: Using a computer-generated sequence, we randomly assigned (1:1) patients with advanced cancer to a group that received a video and workbook that both discussed either ACP (intervention group) or cancer pain control (control group). At baseline, immediately after intervention, and at 7 weeks, we evaluated the subjects' preferences. The primary outcome was preference for EOL care (active treatment, life-prolonging treatment, or hospice care) on the assumption of a fatal disease diagnosis and the expectation of death 1) within 1 year, 2) within several months, and 3) within a few weeks. We used Bonferroni correction methods for multiple comparisons with an adjusted P level of 0.005. RESULTS: From August 2017 to February 2018, we screened 287 eligible patients, of whom 204 were enrolled to the intervention (104 patients) or the control (100 patients). At postintervention, the intervention group showed a significant increase in preference for active treatment, life-prolonging treatment, and hospice care on the assumption of a fatal disease diagnosis and the expectation of death within 1 year (P < 0.005). Assuming a life expectancy of several months, the change in preferences was significant for active treatment and hospice care (P < 0.005) but not for life-prolonging treatment. The intervention group showed a significant increase in preference for active treatment, life-prolonging treatment, and hospice care on the assumption of a fatal disease diagnosis and the expectation of death within a few weeks (P < 0.005). From baseline to 7 weeks, the decrease in preference in the intervention group was not significant for active treatment, life-prolonging treatment, and hospice care in the intervention group in the subset expecting to die within 1 year, compared with the control group. Assuming a life expectancy of several months and a few weeks, the change in preferences was not significant for active treatment and for life-prolonging treatment but was significantly greater for hospice care in the intervention group (P < 0.005). CONCLUSION: ACP interventions that included a video and an accompanying book improved preferences for EOL care.

A clinical pilot study of jawbone mineral density measured by the newly developed dual-energy cone-beam computed tomography method compared to calibrated multislice computed tomography.

PURPOSE: This clinical pilot study was performed to determine the effectiveness of dual-energy cone-beam computed tomography (DE-CBCT) in measuring bone mineral density (BMD). MATERIALS AND METHODS: The BMD values obtained using DE-CBCT were compared to those obtained using calibrated multislice computed tomography (MSCT). After BMD calibration with specially designed phantoms, both DE-CBCT and MSCT scanning were performed in 15 adult dental patients. Three-dimensional (3D) Digital Imaging and Communications in Medicine data were imported into a dental software program, and the defined regions of interest (ROIs) on the 3-dimensional surface-rendered images were identified. The automatically-measured BMD values of the ROIs (g/cm3), the differences in the measured BMD values of the matched ROIs obtained by DE-CBCT and MSCT 3D images, and the correlation between the BMD values obtained by the 2 devices were statistically analyzed. RESULTS: The mean BMD values of the ROIs for the 15 patients as assessed using DE-CBCT and MSCT were 1.09±0.07 g/cm3 and 1.13±0.08 g/cm3, respectively. The mean of the differences between the BMD values of the matched ROIs as assessed using DE-CBCT and calibrated MSCT images was 0.04±0.02 g/cm3. The Pearson correlation coefficient between the BMD values of DE-CBCT and MSCT images was 0.982 (r=0.982, P<0.001). CONCLUSION: The newly developed DE-CBCT technique could be used to measure jaw BMD in dentistry and may soon replace MSCT, which is expensive and requires special facilities.
