Impact of mindfulness training on avoidant coping and advance care planning.

Abstract

86 Background: Timely end-of-life (EOL) discussions and advance care planning (ACP) are crucial to quality cancer care; however, patients, family caregivers (CGs), and oncologists often avoid these tender conversations. When EOL discussions are avoided, patients are more likely to receive non-beneficial treatment near death and CGs are more likely to experience psychiatric disturbance. Mindfulness meditation facilitates emotional regulation and may enhance adaptive coping necessary for EOL discussions and ACP. Methods: Mindfully Optimizing Delivery of End-of-Life (MODEL) Care is a within-group pilot study developed to train patients with advanced-stage solid malignancies and their CGs (n=13 dyads) in present-moment awareness and non-reactive coping through a variety of mindfulness practices. Eligible patients met a threshold for avoidant coping and had not completed a Physician Orders for Scope of Treatment (POST) form documenting care preferences. Cognitive avoidance and quality of life (QoL) for patients and CGs were assessed from baseline (T1) to post-intervention (T2) and 1-month follow-up (T3) with standardized response mean (SRM) effect sizes. ACP from T1 to T3 was assessed descriptively. Results: Moderate decreases in cancer-related avoidance were found for patients (SRM=-0.47) and CGs (SRM=-0.59) T1 to T2, while T1 to T3 effects were small for patients (SRM=-0.31) and large for CGs (SRM=-1.12). At T1, no patient had completed a POST form; by T3, 50% reported completing one and 40% were preparing to do so soon. At T1, 23% of patients reported having had a ‘goals of care’ discussion with their oncologist, with 82% doing so by T3. At T1, 46% of patients reported having discussed ‘goals of care’ with their CGs, with 100% doing so by T3. Large improvements in QoL were found at both time points for patients and CGs (SRMs ranging from 0.85 to 1.21). Conclusions: Mindfulness was associated with mostly moderate reductions in avoidant coping and large improvements in QoL for patients and caregivers, with notable ACP progress for patients.
