Prevalence of Value-Based Care for Older People with Dementia Likely to Be Nearing End of Life: A Hospital Retrospective Cohort

<b>Background</b>: Patients with dementia (PwD) nearing end of life (nEOL) do not always receive optimal end-of-life care, including timely specialist palliative care input. In hospitalized PwD likely to be nEOL, we aimed to determine the prevalence of goals of care discussions; the incidence and timing of referral to palliative care; factors associated with palliative care referral and timely (within 2 days) palliative care referral; and the prevalence of polypharmacy (>5 medications) and in-hospital deprescribing (cessation). <b>Methods</b>: A retrospective chart review of a cohort of PwD admitted under geriatric medicine 1 July 2021-30 June 2022 was conducted, screening to identify nEOL status. <b>Results</b>: A total of 298 patients (mean age of 83.5 [SD 7.4] and 51.3% females) were included in the final analysis. Eleven percent of eligible patients (33/298) died during admission. Overall, 80.9% had discussed an advance care plan (ACP). The mean time from admission to the discussion of an ACP was 1 day (SD = 5.02). One in twenty (5.4%) had their goals of care revised during admission, with 15 transitioning to palliation. Only 7.1% were referred to palliative care during admission. The mean time to referral was 9.8 days (SD 7.3; range 0-26). One in fourteen (7.4%) were discharged from hospital on an end-of-life pathway. In multivariable analysis, both the clinical frailty score (CFS) (aOR per unit increase 3.66; 95%CI 1.65-8.09, <i>p</i> = 0.001) and meeting ≥ 2 deterioration criteria (per CriSTAL tool) (OR 3.68; 95% CI 1.07-12.70, <i>p</i> = 0.039) were independently associated with referral to palliative care. Polypharmacy was common at admission (76.2%), with a mean number of medications of 8.4 (SD = 4). The median number of medications ceased during admission was two (IQR 0-4). <b>Conclusions</b>: Contrary to our hypothesis, we found a high quality of care of PwD likely nEOL, reflected by frequent ACPs in hospital, but it fell short of palliative care specialist input. Polypharmacy on admission and discharge may be further improved by aligning medication use with goals of care among PwD approaching the end of life, and considering the hospital nurse-driven identification of practice gaps is encouraged.
