Inpatients With Dementia Referred for Palliative Care Consultation: A Multicenter Analysis.

Background And Objectives: Specialty palliative care (PC) may benefit patients with dementia by aligning treatment with goals and relieving symptoms. We aimed to compare demographics and processes and outcomes of PC for inpatients with dementia with those with systemic illnesses or cancer.

Methods: This multicenter cohort study included standardized data for hospitalized patients with a primary diagnosis of dementia, systemic illnesses (cardiovascular, pulmonary, hepatic, or renal disease), or cancer among the 98 PC teams submitting data to the Palliative Care Quality Network from 2013 to 2019.

Results: Of 155,356 patients, 4.5% (n = 6,925) had a primary diagnosis of dementia, 32.5% (n = 50,501) systemic illness, and 29.2% (n = 45,386) cancer. Patients with dementia were older (mean 85.5 years, 95% confidence interval [CI] 85.3-85.6) than those with systemic illnesses (mean 73.2, 95% CI 73.0-73.3) or cancer (mean 66.6, 95% CI 66.4-66.7; < 0.0001). Patients with dementia were more likely to receive a PC consult within 24 hours of admission (52.3% vs systemic illnesses 37.4%; cancer 45.3%; < 0.0001), more likely to be bed-bound (vs systemic illnesses odds ratio (OR) 2.23, 95% CI 2.09-2.39, < 0.0001; vs cancer OR 3.45, 95% CI 3.21-3.72, < 0.0001), and more likely to be discharged alive (vs systemic illnesses OR 2.22, 95% CI 2.03-2.43, < 0.0001; vs cancer OR 1.51, 95% CI 1.36-1.67, < 0.0001). Advance care planning/goals of care (GOC) was the primary reason for consultation for all groups. Few patients overall had advance directives or Physician Orders for Life-Sustaining Treatment before consultation. At the time of referral and at discharge, patients with dementia were more likely to have a code status of do not resuscitate/do not intubate (DNR/DNI) (62.6% and 81.0% vs 38.7 and 64.2% for patients with systemic illnesses and 33.4% and 60.5% for patients with cancer; < 0.0001). Among the minority of patients with dementia that could self-report, moderate-to-severe symptoms were uncommon (pain 6.4%, anxiety 5.8%, nausea 0.4%, and dyspnea 3.5%).

Discussion: Inpatients with a primary diagnosis of dementia receiving PC consultation were older and more functionally impaired than those with other illnesses. They were more likely to have a code status of DNR/DNI at discharge. Few reported distressing symptoms. These results highlight the need for routine clarification of GOC for patients with dementia.
