Impact of Specialty and Nonspecialty Palliative Care on Quality of Dying With Alzheimer's Disease or Related Dementias: A Systematic Review and Meta-Analysis.

BACKGROUND

Older adults with Alzheimer's disease and related dementias can benefit from palliative care (PC). Whether specialty and nonspecialty PC have the same effect on outcomes is unclear. We examined the effects of these 2 interventions on comfort, symptom management, satisfaction with care, and potentially burdensome transitions, including hospital admission, emergency department visit, intensive care unit admission in the end-of-life, and in-hospital death.

METHODS

This PRISMA-adherent systematic review involved a search of PubMed, Medline, EMBASE, Cochrane Library, ProQuest, and CINAHL for studies published from January 1, 2013, to November 4, 2024. Primary studies that reported at least one of the 7 patient-level outcomes were included: Comfort Assessment in Dying with Dementia (CAD-EOLD), Symptom Management at the End-of-Life (SM-EOLD), Satisfaction with Care at the End-of-Life in Dementia (SWC-EOLD), hospital admissions, emergency department visits, intensive care unit admissions, and in-hospital death.

RESULTS

Nineteen articles involving 142,772 participants were included. The evidence, comprising studies of adequate to strong quality, revealed that both specialty and nonspecialty PC did not differ in terms of comfort, symptom management, or satisfaction with care. However, both approaches significantly reduced the likelihood of intensive care unit admissions and in-hospital deaths. Specialty PC was associated with decreased emergency department visits (OR 0.53, 95% CI 0.28-1.00; I2=86%).

CONCLUSIONS

Future research is needed to understand factors influencing PC interventions that can improve comfort, symptom management, and care satisfaction for these individuals and their families.
