Difference in the Care of Patients with Amyotrophic Lateral Sclerosis With and Without Intervention from the Palliative Care Team: Observations from a Center in Japan

Background: Despite the significant palliative care needs for people living with amyotrophic lateral sclerosis (ALS), palliative medicine in Japan is mainly focused on oncologic disease. Objective: To compare the care provided to patients with ALS with and without intervention from the palliative care team (PCT and non-PCT groups, respectively). Design: This is a retrospective case-control study. Setting: One ALS center in Japan. Participants: Sixty patients with clinically definite ALS treated until death from January 2012 to December 2019. Measurements: We compared the two groups based on the presence of advance directives, patient age, use of noninvasive and invasive ventilation, maximum opioid dosage, and use of nonopioid palliative medications such as antidepressants and anxiolytics. We also compared the prescribing practices of the attending physicians. Results: There was no difference in the rate of advance directive completion between the PCT and non-PCT groups. Although all but one patient in the PCT group used opioids, only half of the patients in the non-PCT group used opioids (p < 0.001). The mean maximum opioid dosage was higher in the PCT group than in the non-PCT group (p = 0.003). Moreover, 79.2% and 41.7% of the PCT and non-PCT groups, respectively, received antidepressants or antianxiety agents (p = 0.004). Maximum opioid dosages were not different on the basis of attending physician's experience level. Conclusions: Opioid and nonopioid medications intended for symptom management were more likely to be prescribed to patients with ALS who received intervention from a PCT.
