Variation in Patient-Reported Decision-Making Roles in the Last Year of Life among Patients with Metastatic Cancer: A Longitudinal Study.

Abstract

We investigated the variation in patient-reported decision-making roles in the past year of life among patients with metastatic solid cancer and the associations of these roles with patient quality of life and perceived quality of care. We used the last year of life data of 393 deceased patients from a prospective cohort study. Patients reported their decision-making roles, quality of life (emotional well-being, spiritual well-being, and psychological distress) and perceived quality of care (care coordination and physician communication) every 3 months until death. We used mixed effects linear regressions to investigate the associations of decision-making roles with patients' quality of life and perceived quality of care. The most reported roles, on average, were patient-led (37.9%) and joint (23.4%; with physicians and/or family caregivers) decision making, followed by no patient involvement (14.8%), physician/family-led (12.9%), and patient alone (11.0%) decision making. Patient level of involvement in decision making decreased slightly as death approached (P < 0.05). Compared with no patient involvement, joint decision making was associated with better emotional well-being (β [95% confidence interval] = 1.02 [0.24, 1.81]), better spiritual well-being (1.48 [0.01, 2.95]), lower psychological distress (-1.99 (-3.21, -0.77]), higher perceived quality of care coordination (5.04 [1.24, 8.85]), and physician communication (5.43 [1.27, 9.59]). Patient-led decision making was associated with better spiritual well-being (1.69 [0.24, 3.14]) and higher perceived quality of care coordination (6.87 [3.17, 10.58]) and physician communication (6.21 [2.15, 10.27]). Joint and patient-led decision-making styles were reported by 61% of the patients and were associated with better quality of life and quality of care. A decrease in the level of patient involvement over time indicates reliance on family and physicians as death approached. Among patients with metastatic cancer, the level of patient involvement in decision making decreased slightly as death approached.Joint decision making of patients with their physicians and/or family caregivers and patient-led decision making were associated with better quality of life and perceived quality of care.Patients with metastatic cancer should be encouraged to be involved in decision making together with their physicians and/or family caregivers to potentially improve their end-of-life experience.
