AbstractBackground: Caregivers are decision stakeholders; yet, few interventions have been developed to help patients and caregivers collaborate on advance care planning (ACP). Objective: To evaluate a theory-based ACP pilot intervention, Deciding Together, to improve decisional quality, readiness, collaboration, and concordance in ACP decisions for older adult home health (HH) patients and caregivers. Design: A one-group, pre- and posttest study using matched questionnaires was conducted. The intervention consisted of a clinical vignette, theoretically guided conversation prompts, and a shared decision-making activity. Setting/Subjects:N = 36 participants (n = 18 HH patients; n = 18 family and nonfamily caregivers) were purposively recruited from a HH agency to participate in the intervention at patients' homes. Measurements: Demographic and baseline measures were collected for relationship quality, health status, and previous ACP engagement. Outcome measures included perceptions of collaboration, readiness for ACP, concordance in life-sustaining treatment preferences (cardiopulmonary resuscitation, antibiotics, artificial nutrition and hydration, and mechanical ventilation), and decisional conflict. Descriptive statistics, Cohen's κ coefficients, paired t tests, McNemar's tests, and Wilcoxon signed-rank tests (and effect size estimates, r = z/√N) were calculated using R-3.5.1 (p < 0.05). Single value imputation was used for missing values. Results: While no significant differences were found for perceptions of collaboration, and readiness for ACP, patients (r = 0.38, p = 0.02) and caregivers (r = 0.38, p = 0.02) had reduced decisional conflict at posttest. Patients' and caregivers' agreement increased by 27.7% for an item assessing patients' preference for artificial nutrition and hydration (p = 0.03). Conclusions: This study suggests that collaborative ACP decision making may improve decisional conflict for older adult HH patients and their caregivers.
