Patient-family communication mediates the relation between family hardiness and caregiver positivity: Exploring the moderating role of caregiver depression and anxiety.

Purpose: Despite the theoretical and empirical significance of positive aspects of caregiving in caregiver well-being, relatively little is known regarding family-related predictors of caregiver positivity. This study examines whether patient-family communication (p-f communication) mediates the relation between family hardiness and caregiver positivity and whether the mediating effects of p-f communication are moderated by the levels of caregiver depression and anxiety. Design/Sample: This study used secondary data obtained from a large-scale cross-sectional national survey conducted in South Korea. Participants were 544 spousal cancer patient-caregiver dyads recruited from the National Cancer Center and nine government-designated regional cancer centers in South Korea. Methods: To test the hypotheses, a simple mediation model and two moderated mediation tests were conducted using the PROCESS macro for SPSS. Findings: Higher family hardiness was related to higher p-f positive communication and higher caregiver positivity. The effects of family hardiness were partially mediated by p-f communication, controlling for caregiver sex, education, health status, depression and anxiety, time spent caregiving, and patient depression and anxiety, cancer stage, and time since diagnosis. The mediating effects of p-f communication were not significantly moderated by caregiver depression and anxiety. Conclusions/Implications: Health care professionals could consider p-f communication as a reasonable target of intervention to increase caregiver positivity, even for caregivers with heightened depression and anxiety.

Patients' and family caregivers' understanding of the cancer stage, treatment goal, and chance of cure: A study with patient-caregiver-physician triad.

OBJECTIVE: Accurate understanding of the extent of disease, treatment goal, and prognosis is a prerequisite for patients with cancer and their caregivers to make informed decision. We sought to evaluate patients' and family caregivers' understanding of the cancer stage, treatment goal, and chance of cure taking their own physician's evaluation as reference. METHODS: A national survey was performed with 750 patient-caregiver dyads (75.5% participation rate) recruited by 134 oncologists in 13 cancer centers (93% participation rate) in South Korea. Both patients and caregivers were asked to report their knowledge of patient's cancer stage, treatment goal, and chance of cure. Concordance was evaluated with percentage agreement and weighted κ, and predictors of discordance of patient and caregiver's response with that of physician's were explored by multivariate regression analyses with mixed effect model. RESULTS: The agreement rates between patient-physician and caregiver-physician were 63.0% and 65.9% for disease stage, 69.0% and 70.0% for treatment goal, and 41.4% and 45.1% for chance of cure. When discordance occurs, patients and caregivers often had an optimistic view. Distant stage, older age, female sex, and absence of depression were associated with optimistic view of patients, and there was significant between-physician variance for all 3 outcomes. CONCLUSION: The discordance revealed that our study suggests the need for better communication between physician and patients, as well as the caregivers. Research is needed to develop a comprehensive strategy to improve the understanding of the patients and family so that treatment decisions are made based on realistic estimation.

School performance of childhood cancer survivors in Korea: A multi-institutional study on behalf of the Korean Society of Pediatric Hematology and Oncology.

OBJECTIVE: To investigate school performance of childhood cancer survivors focusing on the child's functioning, including peer relationships, school attendance, and academic achievement. METHODS: We studied 241 children from 15 institutions in Korea between 2015 and 2016. The self-reported paper-and-pencil questionnaires were used. RESULTS: Approximately 22% of the survivors suffered from lack of friends. Bullying was reported by 30% of survivors. Survivors who returned to primary school reported a higher incidence of bullying compared with survivors who returned to middle or high school (P = 0.03). The percentage of children who missed classes more than 4 days in a month was higher in survivors with brain tumors than those with other tumors (P = 0.04). Approximately 41% of children reported learning difficulty. After returning to school, 53% of the patients reported that they had lower overall mark averages than they had before. Patients who returned to high school showed the highest rate of repeating a grade and the lowest rate of achieving high academic marks. The school marks in the Korean (P = 0.03), English (P = 0.04), and physical education (P = 0.04) were worse for the children with brain tumors than for the children with other tumors. CONCLUSION: We found that 20% to 25% of survivors experienced peer-related difficulties upon returning to school. Patients who return to school, especially high school, should be provided more educational support to overcome low academic achievement. Particular concern is needed to the patients with brain tumors, who are at risk for significant academic and social difficulties and therefore may require more intensive support in school.

Cancer cost communication: experiences and preferences of patients, caregivers, and oncologists-a nationwide triad study.

PURPOSE: We assessed cost communication between cancer patients, caregivers, and oncologists and identified factors associated with communication concordance. METHODS: A national, multicenter, cross-sectional survey of patient-caregiver-oncologist triads was performed, and 725 patient-caregiver pairs, recruited by 134 oncologists in 13 cancer centers, were studied. Discordance in preferences and experiences regarding cost communication between patients, caregivers, and oncologists were assessed. Hierarchical generalized linear models were used to identify predictors of concordance and to identity the possible association of concordance with patient satisfaction and degree of trust in the physician. RESULTS: Although the oncologists thought that patients would be affected by the cost of care, only half of them were aware of the subjective burden experienced by their patients, and the degree of concordance for this parameter was very low (weighted kappa coefficient = 0.06). Caregivers consistently showed similar preferences to those of the patients. After controlling for covariates, the education level of patients [adjusted odds ratio (aOR) for > 12 vs. < 9 years, 2.92; 95% confidence interval (CI), 1.87-4.56], actual out-of-pocket costs [aOR for ≥ 8 million vs. < 2 million Korean Won, 0.56; 95% CI, 0.34-0.89], and physician age (aOR for ≥ 55 vs. < 45 years, 1.83; 95% CI, 1.04-3.21) were significant. CONCLUSIONS: The results show underestimation by oncologists regarding the subjective financial burden on a patient, and poor patient-physician concordance in cost communication. Oncologists should be more cognizant of patient OOP costs that are not indexed by objective criteria, but instead involve individual patient perceptions.

Income Difference in Attitudes towards Cancer in General Population: Findings from a National Survey.

BACKGROUND: To better understand cancer-related health behaviors, it is critical to know how general populations with different socioeconomic and demographic backgrounds perceive cancer. The current paper explored differences in general attitudes and beliefs towards cancer among Koreans. METHODS: A cross-sectional national survey was conducted for 1,000 Korean participants who were not cancer patients and did not have immediate family members with cancer via proportional quota random sampling. General attitudes and beliefs about cancer were measured by face-to-face interview using the awareness and beliefs about cancer (ABC) measure. RESULTS: Most respondents (84.8%-88.5%) had optimistic attitudes towards cancer. However, 35.6% to 87.7% agreed with negative cancer beliefs across all age groups simultaneously. Socioeconomic disparity of positive cancer beliefs was not evident. Unexpectedly, the highest income group agreed more strongly with the negatively framed statements that cancer treatment is worse than the cancer itself (odds ratio [OR], 2.68; 95% confidence interval [CI], 1.31-5.53), that they would not want to know if they have cancer (OR, 1.61; 95% CI, 0.94-2.75), and that a cancer diagnosis is a death sentence (OR, 2.32; 95% CI, 1.34-4.01), than the lowest income group. CONCLUSION: The present results imply a complicated context of cancer beliefs in Korea, unlike those shown in the studies of western populations. While the contradictory attitudes toward cancer can be attributable to the dual nature of information processing, social environment might have played a role. The association between socioeconomic status and negative attitudes toward cancer may vary depending on the diversity of the contexts.

Attitudes Toward Family Involvement in Cancer Treatment Decision Making: The Perspectives of Patients, Family Caregivers, and Their Oncologists.

BACKGROUND: To investigate how cancer patients, family caregiver, and their treating oncologist view the risks and benefits of family involvement in cancer treatment decision making (TDM) or the degree to which these perceptions may differ. PATIENTS AND METHODS: A nationwide, multicenter survey was conducted with 134 oncologists and 725 of their patients and accompanying caregivers. Participant answered to modified Control Preferences Scale and investigator-developed questionnaire regarding family involvement in cancer TDM. RESULTS: Most participants (>90%) thought that family should be involved in cancer TDM. When asked if the oncologist should allow family involvement if the patient did not want them involved, most patients and caregivers (>85%) thought they should. However, under this circumstance, only 56.0% of oncologists supported family involvement. Patients were significantly more likely to skew their responses toward patient rather than family decisional control than were their caregivers (P < .003); oncologists were more likely to skew their responses toward patient rather than family decisional control than caregivers (P < .001). Most respondents thought that family involvement is helpful and neither hamper patient autonomy nor complicate cancer TDM process. Oncologists were largely positive, but less so in these ratings than either patients or caregivers (P < .002). CONCLUSIONS: Patients, family caregivers, and, to a lesser degree, oncologists expect and valued family involvement in cancer TDM. These findings support a reconsideration of traditional models focused on protection of patient autonomy to a more contextualized form of relational autonomy, whereby the patient and family caregivers can be seen as a unit for autonomous decision.

Awareness about past diagnosis and treatment history: nationwide survey of childhood cancer survivors and their parents.

OBJECTIVE: To assess the awareness of past medical history and long-term care issues of childhood cancer survivors (CCS) in Korea. METHODS: A nationwide survey was conducted on CCS and their parents in 10 regional cancer centers in Korea. Answers regarding cancer diagnosis and treatment history were compared with the treatment summary and categorized into three ('specific,' 'general,' and 'no') or two ('yes' and 'no') groups. RESULTS: Out of 343 contacts, 293 dyads completed the survey, and 281 dyads were analyzed. Awareness of cancer diagnosis was mostly specific for parents (76.5%) and CCS (35.2%). Awareness of anti-cancer treatment exposure was mostly general (84.6% for surgery, 67.9% for chemotherapy, and 53.9% for hematopoietic stem cell transplantation) rather than specific. In particular, more than half of the parents were not aware of the exposure to cardiotoxic agents (72.9%) or radiation therapy (56.3%). Providing information about long-term side effects and prevention of secondary cancer was significantly correlated only with more concern and more follow-up visits (P ≤ 0.001, respectively), without correlation with more specific awareness of exposure to cardiotoxic agents or radiation. CONCLUSION(S): Most of the parents of CCS were not aware of treatment-related risk factors necessary for long-term care. Providing information was significantly correlated with more concern and more follow-up visits, without improving corresponding knowledge about their past medical history. Effort aimed towards improving awareness about risk factors, the manner of providing information, and the patient referral system within which we use this information is warranted.

Perceived social support and its impact on depression and health-related quality of life: a comparison between cancer patients and general population.

OBJECTIVE: It is well known that cancer patients' perception of social support is associated with their depressive symptoms and health-related quality of life. However, there have been little studies that compared the variates of cancer patients with the general population. We sought to compare differences in the level of perceived social support and the impact of perceived social support on depressive symptoms and health-related quality of life between cancer survivors and the general population. METHODS: Data were collected from 1818 cancer patients treated at the National Cancer Center and regional cancer centers in South Korea. The control group of the general population was composed of 2000 individuals without cancer from community. RESULTS: Cancer patients reported significantly higher level of perceived social support than the general population, while they reported lower health-related quality of life and were more susceptible to depression. The positive associations of higher perceived social support with lower depressive symptoms, as well as with higher health-related quality of life, were stronger among cancer patients than among the general population. CONCLUSIONS: The interaction effect suggests that the impact of social support would be stronger among cancer patients than the general public. Thus, it would be beneficial to pay attention to providing social support to cancer patients, particularly to those who are more vulnerable. Furthermore, investigation of the most effective and efficient methods to deliver social support interventions would be worthwhile.

High liver fibrosis index FIB-4 is highly predictive of hepatocellular carcinoma in chronic hepatitis B carriers.

UNLABELLED: Screening for hepatocellular carcinoma (HCC) is clinically important given that its early detection has remarkable survival benefits. We investigated the possible role of FIB-4, a recently developed noninvasive marker for liver fibrosis based on routine laboratory tests, as a clinical indicator for predicting future HCC among hepatitis B surface antigen (HBsAg) carriers. Our retrospective cohort study involved 986 Korean HBsAg carriers 40 years of age or older who visited Seoul National University Hospital for a health checkup. National medical service claims data were used to determine HCC incidence. Median follow-up time was 5.4 years (interquartile range: 4.4 years). Adjusted for age, sex, body mass index, smoking, alcohol, and antiviral medication for hepatitis B, compared to subjects with FIB-4 <1.25, subjects with 1.7≤ FIB-4 <2.4 showed an adjusted hazard ratio (aHR) of 4.57 (95% confidence interval [CI]: 1.50-13.92) and subjects with FIB-4 ≥2.4 showed an aHR of 21.34 (95% CI: 7.73-58.92) for HCC incidence. FIB-4 was shown to have incremental predictive value to ultrasonographic liver cirrhosis for HCC incidence (C-index: 0.701 vs. 0.831; P = 0.001). FIB-4 was also better predictive of HCC incidence, compared to that of ultrasonographic liver cirrhosis (C-index: 0.775 vs. 0.701; P = 0.040). CONCLUSION: High FIB-4 is a highly predictive risk factor for HCC incidence among Korean HBsAg carriers. FIB-4 is a promising, easily applicable, and cost-effective clinical tool in identifying a subpopulation of HBsAg carriers who are at heightened risk. Our study needs to be replicated in larger future studies on various ethnic groups; nonetheless, our study suggests that FIB-4 may play a valuable role in HCC screening among HBsAg carriers.

Avoidance of cancer communication, perceived social support, and anxiety and depression among patients with cancer.

PURPOSE: Patients with cancer are reported to experience high anxiety and depression related to their medical status. The current study aimed to investigate the effects of avoidance of cancer communication and of social support from family and medical professionals on the patients' anxiety and depression. METHODS: A national survey was conducted through regional branches of the National Cancer Center of South Korea, which yielded 296 patient-caregiver dyads. Patients' medical records complemented their self-report survey data. RESULTS: Patients' anxiety was predicted by the family's avoidance of cancer communication and the level of emotional support from family. Patients' depression was predicted by the stage of cancer (Surveillance, Epidemiology, and End Results), the family's avoidance of cancer communication, the emotional support from family, and the medical professionals' respect. Interaction effects were not statistically significant. CONCLUSION: The implications of the findings are discussed in terms of the psycho-oncological and psycho-social interventions.

The effects on caregivers of cancer patients' needs and family hardiness.

OBJECTIVES: Family caregivers of cancer patients are anticipated to serve multiple roles but the factors that influence their reaction to caregiving have not gotten much attention. The current study aimed to investigate the effects of cancer patient's needs level and the family hardiness on the caregivers' reaction. METHODS: A national survey was conducted through regional branches of the National Cancer Center of South Korea, yielding 990 patient-caregiver dyads. Patients and caregivers provided self-report questionnaires. Patient's medical records complemented the self-report survey data. RESULTS: On all five domains of caregiver reaction, which were schedule, esteem, support, health, and finance, family hardiness was a significant predictor. Male, older, low-income caregivers reported more burden in caregiving with some. The interaction effect of patient's needs and family hardiness was found only on esteem. CONCLUSIONS: The implications based on the findings are discussed in terms of the psycho-oncological and psycho-social interventions for the cancer patients and their family caregivers.

Attitudes towards second opinion services in cancer care: a nationwide survey of oncologists in Korea.

OBJECTIVE: Second opinion is a common phenomenon in many health systems, especially in the care of patients with cancer. However, it is not clear whether second opinion seeking should be promoted or discouraged and how second opinion services and policies can be better formalized to maximize the benefits and minimize the disadvantages. METHODS: A nationwide survey was conducted with a representative sample of 678 physicians involved in cancer care (75.5% participation rate) recruited in 13 cancer centres. RESULTS: Most physicians involved with cancer care perceived patients' second opinion seeking as a legitimate right (96.0%) and they acknowledged the need for second opinion services under certain conditions (98.2%). Many believed that second opinions can enhance patient satisfaction (77.3%) and quality of care (74.3%), but they also had concerns about increase in healthcare and societal costs (91.3%) and concentration in a high-volume centre (90.7%). While the majority agreed with the involvement of the first opinion physicians in the second opinion services (69.5%), there were mixed opinions regarding the desirability of remote (teleconsultation) second opinion services (49.0%) and coverage by national health insurance (51.9%). CONCLUSION: Physicians were generally positive to second opinion services and expected positive consequences in terms of patient satisfaction and quality of care. However, they had concerns about the consequences regarding cost and equity, and disagreements were observed regarding the way to improve second opinion services. The physicians' opinions revealed in our study will be helpful in developing clearer guidelines used to maximize the benefits of second opinion services.

Attitudes toward participating in Phase I clinical trials: an investigation with patient-family-physician triads.

OBJECTIVE: Phase I oncology trials have raised concerns that patients' 'unrealistic' optimism could compromise the validity of informed consent, and that patients often participate in trials to conform to physicians' or family members' recommendations. We aimed to determine whether patients or families-given the same information of risk-benefit profile-are more likely to participate in Phase I trials than their physicians and whether people in family or physician situations are more likely to recommend trial participation to patients than they would want for themselves as patients. METHODS: We conducted a hypothetical vignette study with a patient-caregiver-oncologist. Three groups-725 patient-caregiver pairs recruited by 134 oncologists-were asked to assume three different roles as patients, caregivers and physicians and provided a scenario of a hypothetical patient with treatment-resistant cancer. They were asked questions regarding their intention to participate in or to recommend a Phase I clinical trial. RESULTS: Acceptance rates of the trial were as follows: (a) in the patients' role: patients (54.1), caregivers (62.3) and physicians (63.4%); (b) in the caregivers' role: 55.6, 64.7 and 70.9%; (c) in the physicians' role: 66.1, 70.8 and 76.1%. Patients or caregivers were not more positive to the trial than physicians. All three groups showed more positive attitudes toward the clinical trial when they assumed the role of caregiver or physician than that of patient. CONCLUSIONS: Patients and caregivers seem to make as reasonable decisions as physicians; patients seem to take family members' or physicians' recommendation as their legitimate roles rather than as undue pressure.

Prediction of future hepatocellular carcinoma incidence in moderate to heavy alcohol drinkers with the FIB-4 liver fibrosis index.

BACKGROUND: Although heavy alcoholics are at heightened risk for hepatocellular carcinoma (HCC), there are no guidelines that recommend HCC screening for heavy alcoholics. This study investigated FIB-4, a noninvasive and easily applicable liver fibrosis index, as a risk factor for HCC incidence among alcohol drinkers without viral hepatitis. METHODS: This retrospective cohort study included 6661 generally healthy adults who were 30 years old or older, did not have chronic viral hepatitis, and visited Seoul National University Hospital for a general, routine health evaluation. The future HCC incidence was determined from National Health Insurance medical service claims data (median follow-up, 6.2 years). RESULTS: With adjustments for age, sex, body mass index, smoking, and alcohol, compared with subjects with FIB-4 values less 1.00, subjects with FIB-4 values greater than or equal to 1.75 and less than 2.10 and subjects with FIB-4 values greater than or equal to 2.10 had adjusted hazard ratios (aHRs) of 5.18 (95% confidence interval [CI], 1.12-24.00) and 13.63 (95% CI, 3.77-49.33), respectively, for HCC incidence. This was heightened in subjects who drank more 30 g of alcohol per day: the aHRs were 8.39 (95% CI, 1.28-54.87) and 16.58 (95% CI, 3.87-71.04), respectively. FIB-4 was shown to have a higher predictive value for HCC incidence than ultrasonographically detected liver cirrhosis (C-index, 0.665 vs 0.527; P = .044). CONCLUSIONS: High FIB-4 is a risk factor with a high predictive value for HCC incidence, especially among moderate to heavy alcoholics (>30 g/d). FIB-4 is a readily available and probably cost-effective clinical tool with potential value for identifying subpopulations of alcoholics at particularly high risk who would benefit from regular HCC screening. Further investigations are warranted to validate our results; nonetheless, our study suggests that FIB-4 may be useful in HCC screening among alcoholics.

Determinants of gastric cancer screening attendance in Korea: a multi-level analysis.

BACKGROUND: We aimed to assess individual and area-level determinants of gastric cancer screening participation. METHOD: Data on gastric cancer screening and individual-level characteristics were obtained from the 2007-2009 Fourth Korea National Health and Nutrition Examination Survey. The area-level variables were collected from the 2005 National Population Census, 2008 Korea Medical Association, and 2010 National Health Insurance Corporation. The data were analyzed using multilevel logistic regression models. RESULTS: The estimated participation rate in gastric cancer screening adhered to the Korea National Cancer Screening Program guidelines was 44.0% among 10,658 individuals aged over 40 years who were included in the analysis. Among the individual-level variables, the highest income quartile, a college or higher education level, living with spouse, having a private health insurance, limited general activity, previous history of gastric or duodenal ulcer, and not currently smoking were associated with a higher participation rate in gastric cancer screening. Urbanization showed a significant negative association with gastric cancer screening attendance among the area-level factors (odds ratio (OR) = 0.73; 95% confidence interval (CI) = 0.57-0.93 for the most urbanized quartile vs. least urbanized quartile). CONCLUSION: There are differences in gastric cancer screening attendance according to both individual and regional area characteristics.

Cross-cultural validation of Cancer Communication Assessment Tool in Korea.

BACKGROUND: Communication between cancer patients and caregivers is often suboptimal. The Cancer Communication Assessment Tool for Patient and Families (CCAT-PF) is a unique tool developed to measure congruence in patient-family caregiver communication employing a dyadic approach. We aimed to examine the cross-cultural applicability of the CCAT in the Korean healthcare setting. METHODS: Linguistic validation of the CCAT-PF was performed through a standard forward-backward translation process. Psychometric validation was performed with 990 patient-caregiver dyads recruited from 10 cancer centers. RESULTS: Mean scores of CCAT-P and CCAT-F were similar at 44.8 for both scales. Mean CCAT-PF score was 23.7 (8.66). Concordance of each items between patients and caregivers was low (weighted kappa values <0.20 for all items and Spearman's rho <0.18 for scale scores). Scale scores did not differ significantly across a variety of cancer types and stages. The CCAT-P or CCAT-F score was weakly associated with mental health and quality of life outcomes. The CCAT-PF was correlated weakly with both patient-perceived and caregiver-perceived family avoidance of cancer care scales. CONCLUSION: The CCAT-PF Korean version showed similar psychometric properties to the original English version in the assessment of communication congruence between cancer patient and family caregivers.

Discordance among patient preferences, caregiver preferences, and caregiver predictions of patient preferences regarding disclosure of terminal status and end-of-life choices.

BACKGROUND: The complexity of end-of-life (EOL) communication in cancer care is often increased by family caregivers, who frequently affect the information and decision-making process. We assessed cancer patient preferences (PP), family caregiver preferences (FCP), and family caregiver predictions of patient preferences (FCPPP) regarding the disclosure of terminal status, family involvement in the disclosure process, and EOL choices, and we evaluated the concordances among them. METHODS: A national, multicenter, cross-sectional survey of 990 patient-caregiver dyads (participation rate = 76.2%) was performed. A set of paired questionnaires was independently administered to patients and their caregivers. RESULTS: While patients and family caregivers had wide spectra of preferences, patients significantly preferred disclosure, direct disclosure by a physician, and palliative care options (all P < 0.001). Family caregiver predictions were similar to PP with regard to terminal disclosure (P = 0.35) but significantly different with regard to family involvement in the disclosure process and EOL choices (P < 0.001). The concordances of PP and FCP (κ = 0.08-0.13), and those of PP and FCPPP (κ = 0.09-0.17), were poor. The concordances of FCP and FCPPP were fair to moderate (κ = 0.35-0.67). Discrepancies between PP and FCP and between PP and FCPPP were associated with dysfunctional family communication. CONCLUSIONS: Family caregivers do not generally concur with patients in their preferences, nor do they reliably predict PP. Open dialogue between patient and family caregivers would reduce the discrepancy. More emphasis on incorporating family caregivers in EOL communication is needed from clinical, research, and training perspectives.

Attitudes toward disclosure of medication side effects: a nationwide survey of Korean patients, caregivers, and oncologists.

BACKGROUND: We aimed to compare the views of cancer patients, family caregivers, and oncologists about the disclosure of side effects in respect to their probability of occurrence, severity, and treatment purpose. We also compared attitudes toward potential harm of side effect disclosure, patients' perceived ability to understand the risk of the side effects, and informed decision-making regarding side effects. METHODS: A national survey was performed with 750 patient-caregiver dyads (75.5% participation rate) recruited by 134 oncologists in 13 cancer centers (93% participation rate). Attitudes toward communication of side effects were assessed in terms of drug purpose, severity of potential complications, and probability of harm. RESULTS: Most patients (82.1-87.0%) and caregivers (75.9-81.5%) thought they should be informed of all possible drug side effects regardless of risk, severity, or drug purpose and wanted these risks to be communicated explicitly. Patients and their caregivers believed that detailed explanations of side effects did not harm patients, and further, they believed that patients could understand risks and make treatment decision based on that information. In contrast, oncologists held less positive attitudes toward providing detailed information about drug side effects, especially if they were not severe and if the drugs were designed for supportive care. CONCLUSION: Cancer patients and family members had different perspectives and preferences regarding communication of drug side effects from their oncologists. The data from our study can serve as a guide for oncologists in presenting side effects information to their patients, as well as a basis for physician training.

Caregiver burden, patients' self-perceived burden, and preference for palliative care among cancer patients and caregivers.

OBJECTIVE: Recently, caregiver burden (CB) has emerged as an important issue in the area of palliative medicine. However, patients' feelings related to being a burden to their families (i.e., self-perceived burden [SPB]) is also a significant issue. We evaluated the relation of CB and SPB as preference for palliative care. METHODS: A national, multicenter, cross-sectional survey of 326 patient-caregiver dyads was performed. A set of paired questionnaires evaluating CB and SPB (five domain items assessed on a four-point Likert scale) were independently administered to patients and their caregivers. Among the respondents, only the patients with distant stage cancer and their caregivers were included. Multivariate analyses were conducted to identify the associations between CB and SPB and preference for palliative care. RESULTS: Caregivers and patients who preferred palliative care to life sustaining treatment reported higher CB and SPB scores, respectively. Caregivers who felt more of a burden were more likely to prefer palliative care over life sustaining treatment for their patients (adjusted odds ratio [aOR] = 1.67, 95% CI: 1.21-2.31). In addition, patients who perceived their caregivers' burden as large tended to prefer palliative care (aOR = 1.61, 95% CI: 1.16-2.22). CONCLUSIONS: Both CB and SPB increased preference for palliative care. This could be interpreted that high CB can lead to preference for palliative care in both patients and their caregivers, potentially threatening patient autonomy. Efforts to relieve CB and SPB are needed.

Association of cardiovascular health screening with mortality, clinical outcomes, and health care cost: a nationwide cohort study.

OBJECTIVE: To determine whether a cardiovascular disease (CVD) health screening program is associated with CVD-related health conditions, incidence of cardiovascular events, mortality, healthcare utilization, and costs. METHODS: Cohort study of a 3% random sample of all Korea National Health Insurance members 40years of age or older and free of CVD or CVD-related health conditions was conducted. A total 443,337 study participants were followed-up from January 1, 2005 through December 31, 2010. RESULTS: In primary analysis, the hazard ratios for CVD mortality, all-cause mortality, incident composite CVD events, myocardial infarction, cerebral infarction, and cerebral hemorrhage comparing participants who attended a screening exam during 2003-2004 compared to those who did not were 0.58 (95% CI: 0.53-0.63), 0.62 (95% CI: 0.60-0.64), 0.82 (95% CI: 0.78-0.85), 0.84 (95% CI: 0.75-0.93), 0.84 (95% CI: 0.79-0.89), and 0.73 (95% CI: 0.67-0.80), respectively. Screening attenders had higher rates of newly diagnosed hypertension, diabetes mellitus, and dyslipidemia, lower inpatient days of stay and cost, and lower outpatient cost compared to non-attenders. CONCLUSIONS: Participation in CVD health screening was associated with lower rates of CVD, all-cause mortality, and CVD events, higher detection of CVD-related health conditions, and lower healthcare utilization and costs.
