Associations Between End-Stage ALS Care and Specialty Palliative Care: A Hypothesis-Generating Study.

Abstract

Introduction/aims: Amyotrophic lateral sclerosis (ALS) care is typically delivered via a multidisciplinary approach that may include specialty palliative care (SPC). Opportunities for SPC to enhance ALS care have been identified; however, investigation of these proposed benefits is scant. In this exploratory study, investigators examined associations between receipt of SPC and variables particularly relevant to end-stage ALS.

Methods: Researchers reviewed electronic health records for all patients with ALS who received standard ALS care from one Midwestern US academic medical center and died between January 1, 2020, and June 30, 2022 (N = 156). Receipt of SPC, duration of illness, hospice enrollment and length of service, report of a healthcare proxy, documentation of a healthcare proxy, participation in goals of care conversations, and location of death were examined.

Results: Patients who received SPC (59%), had lower mean forced vital capacity (FVC) (p < 0.05), and more often used respiratory support (p < 0.001), participated in goals of care conversations (p < 0.001), reported a healthcare proxy (p < 0.01), and enrolled in hospice (p < 0.001) than patients who received standard care alone. No differences between groups were found in duration of illness (mean = 51.7 months), use of assistive feeding, Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) scores (mean = 32.1), documentation of a healthcare proxy, length of hospice stay (mean = 47.3 days), or location of death.

Discussion: Clinical characteristics and end-of-life outcome differences between groups support further investigation of the proposed benefits of SPC regarding hospice enrollment, report of healthcare proxies, and documented goals of care conversations.
