Older patients with hematologic malignancies are increasingly considered for allogeneic hematopoietic cell transplant (allo-HCT). However, older patients often have increased comorbidities and thus may require an increased level of post-transplant care. These factors can contribute to increased caregiver distress, which has been associated with worsened health outcomes for caregivers and patients. To examine predictors of caregiver distress and support group participation in caregivers of older allo-HCT patients, we retrospectively reviewed charts of 208 patients aged 60 and older who underwent their first allo-HCT at our institution from 2014 through 2016. We systematically characterized and identified the incidence of caregiver distress and attendance in a caregiver support group from the start of conditioning through 1 year post allo-HCT. Evidence of caregiver distress and support group participation was recorded by reviewing clinical and/or social work documentation. We found that 20 caregivers (10%) endorsed stress and 44 caregivers (21%) attended our support group at least once. A patient's prior history of psychiatric diagnosis (p = .046) or the use of potentially inappropriate medications for older adults (p = .046) was found to be associated with caregiver stress. Caregivers who were spouses or partners of patients (p = .048) or caregivers of married patients were more likely to attend the support group (p = .007). While limited by retrospective design and likely underreporting, this study reveals factors associated with caregiver distress in the older allo-HCT caregiver population. This information can help providers identify caregivers at risk for distress and improve caregiver resources, which may improve both caregiver and patient outcomes.
