Family Caregiver Grief And Depression Outcomes From The Enable Iii Randomized Controlled Trial

48 Background: Little is known whether early palliative care (PC) support for family caregivers (FCGs) impacts grief and depression after care recipients die. We conducted a randomized controlled trial (RCT) of a nurse-led, phone-based concurrent PC intervention for FCGs delivered at the time of care recipients' advanced cancer diagnosis (early group) or 12 weeks later (delayed group). We hypothesized that grief and depression scores would be lower for early compared to delayed group FCGs.Early vs. delayed RCT (10/2010-9/2013) of 123 FCGs of community dwelling persons with advanced cancer in a rural, New Hampshire NCI-designated comprehensive cancer center and affiliated outreach clinics and a Vermont VA medical center receiving a multicomponent intervention (ENABLE [Educate, Nurture, Advise, Before Life Ends]) consisting of 3 weekly sessions, monthly follow-up, and a bereavement call. FCGs of persons dying during the study period completed the Center for Epidemiological Study-Depression scale (CESD) and the Prigerson Inventory of Complicated Grief-Short Form (PG13) 8-12 weeks after care recipients' deaths. Generalized estimating equations were used to compute group means, standard deviations, and between-group effect size differences.For care recipients who died (n = 70), 44 FCGs (early: n = 19; delayed: n = 25) completed after-death questionnaires. Mean depression scores (CESD) for the early group was 14.6 (SD = 10.7) and for the delayed group was 17.6 (SD = 11.8). Mean grief scores (PG13) for the early group was 22.7 (SD = 4.9) and for the delayed group was 24.9 (SD = 6.9). Between-group effect size differences were not statistically significant (CESD: d = -.27, p = .38; PG13: d = -.36, p = .24).Though statistically insignificant, the magnitude of the observed between-group differences for depression was small and for grief was medium. Considering the small sample size and the delayed group's mean depression score surpassing the clinical cutoff (CESD score > 16), the clinical relevance of these findings cannot be ruled out. Future upstream FCG PC interventions initiated long before end of life should continue to examine intervention effects on FCG after-death outcomes.NCT01245621.
