Abstract

Context: Discordance in prognostic understanding between caregivers of adults with advanced cancer and the oncologist may shape caregivers' views of the oncologist and bereavement outcomes. Objectives: We examined prospective associations of caregiver-oncologist discordance with caregiver-oncologist therapeutic alliance and caregiver anxiety after patient death. Methods: We conducted a secondary analysis of data collected in a cluster randomized controlled trial from August 2012 to June 2014 in Western New York and California. At enrollment, caregivers and oncologists used a seven-point scale to rate their beliefs about the patient's curability and living two years or more: 100%, about 90%, about 75%, about 50 of 50, about 25%, about 10%, and 0%. Discordance was defined as a difference of two points or more. Outcomes at seven months after patient death included caregiver-oncologist therapeutic alliance (The Human Connection scale, modified into five items) and caregiver anxiety (Generalized Anxiety Disorder-7). We conducted multivariable linear regression models to assess the independent associations of discordance with alliance and anxiety. Results: We included 97 caregivers (mean age 63) and 38 oncologists; 41% of caregiver-oncologist dyads had discordant beliefs about the patient's curability, and 63% of caregiver-oncologist dyads had discordant beliefs about living two years or more. On multivariate analysis, discordance in beliefs about curability was associated with lower anxiety (β = −2.20; SE 0.77; P = 0.005). Discordance in beliefs about length of life was associated with a weaker alliance (β = −5.87; SE = 2.56; P = 0.02). Conclusion: A better understanding of how caregivers understand and come to terms with poor prognoses will guide interventions to improve cancer care delivery and outcomes of cancer treatment.
