Burden prediction in cancer caregivers: role of social support and connectedness.

OBJECTIVES: Caregivers play a key role in providing support to people with cancer. However, caregiving can be stressful and demanding, resulting in perceived caregiver burden. Social connectedness is considered partially independent from social support, yet few studies have examined whether social connectedness impacts caregiver burden. The current study sought to examine: (a) associations among social support, social connectedness and burden in a sample of cancer caregivers and (b) the mediating effect of social connectedness on the relationship between social support and caregiver burden. METHODS: A descriptive cross-sectional study was conducted. Data were collected as part of a larger project. The sample included 125 caregiver-cancer care recipient dyads. Caregivers completed the Social Connectedness Scale-Revised, the Medical Outcomes Study-Social Support Survey and the Zarit Burden Interview. Descriptive statistics, hierarchical multiple regression and mediation analyses were used to examine relationships between variables. RESULTS: Correlation analyses showed higher perceived social support and social connectedness were significantly correlated with lower-reported caregiver burden (p<0.05). The hierarchical regression model showed that both social support and social connectedness were independent predictors of caregiver burden (p<0.001). Social connectedness partially mediated the relationship between social support and caregiver burden. CONCLUSIONS: This study provides new evidence that social support buffers the negative effects of burden in caregivers, suggesting these are potentially modifiable factors of caregiver burden. Increased understanding of the factors that contribute to burden among cancer caregivers will inform targeted supportive care strategies to improve psychological health and well-being in this underserved group.

Patient-Reported Communication With Their Health Care Team About New Treatment Options for Chronic Lymphocytic Leukemia.

Chronic lymphocytic leukemia (CLL) often requires consideration of multiple treatment options. Shared decision-making (SDM) is important, given the availability of increasingly novel therapies; however, patient-provider treatment conversations vary. We examined relationships between patient-provider discussions of new CLL treatment options and sociodemographic, clinical, and patient-provider communication variables among 187 CLL patients enrolled in Cancer Support Community's Cancer Experience Registry. Factors significantly associated with self-reports of whether patients' providers discussed new CLL treatment options with them were examined using χ2 tests, t tests, and hierarchical logistic regression. Fifty-eight percent of patients reported discussing new treatment options with their doctor. Patients with higher education were 3 times more likely to discuss new treatment options relative to those with lower education (OR = 3.06, P < .05). Patients who experienced a cancer recurrence were 7 times more likely to discuss new treatment options compared to those who had not (OR = 7.01, P < .05). Findings offer insights into the correlates of patient-provider discussions of new CLL treatment options. As novel therapies are incorporated into standards of care, opportunities exist for providers to improve patient care through enhanced SDM.

Attitudes of intensive care and emergency physicians in Australia with regard to the organ donation process: A qualitative analysis.

Specialized hospital physicians have direct capacity to impact Australia's sub-optimal organ donation rates because of their responsibility to identify and facilitate donation opportunities. Australian physicians' attitudes toward this responsibility are examined. A total of 12 intensive care unit and three emergency department physicians were interviewed using a constructionist grounded theory and situational analysis approach. A major theme emerged, related to physicians' conflicts of interest in maintaining patients'/next-of-kin's best interests and a sense of duty-of-care in this context. Two sub-themes related to this main theme were identified as follows: (1) discussions about organ donation and who is best to carry these out and (2) determining whether organ donation is part of end-of-life care; including the avoidance of non-therapeutic ventilation; and some reluctance to follow clinical triggers in the emergency department. Overall, participants indicated strong support for organ donation but would not consider it part of end-of-life care, representing a major obstacle to the support of potential donation opportunities. Findings have implications for physician education and training. Continued efforts are needed to integrate the potential for organ donation into end-of-life care within intensive care units and emergency departments.
