Abstract
Despite the potential of palliative care (PC) to enhance the quality of life for patients with advanced dementia, there is limited knowledge of its inpatient utilization patterns. This study investigated inpatient PC consultation utilization patterns and evaluated its impact on hospital length of stay (LOS) and medical costs among older patients diagnosed with Alzheimer’s Disease and Related Dementia who were at a high risk of mortality (ADRD-HRM). Using the 2016-2019 National Inpatient Sample database, we conducted multivariable logistic regression analyses to identify individual and hospital characteristics influencing PC consultation utilization. We subsequently performed generalized linear models to estimate LOS (using Poisson distribution) and hospital charges (via log-transformation). Our sample encompassed 965,644 hospital discharges (weighted n = 4,828,219) of patients aged 65 years and above with ADRD-HRM. Among them, 14.6% received inpatient PC. There was a notable uptrend in PC consultation utilization from 13.3% in 2016 to 16.3% in 2019 (p trend<.001). Factors positively influencing and associated with PC utilization included patients that are older, non-Hispanic White, with higher income, receiving care from teaching hospitals, and facilitated with greater bed capacity (all P < .05). Although patients who received PC were more likely to have 3.0% longer LOS (P < .001), they had 19.2% lower hospital charges (P < .001). In conclusion, PC substantially reduced hospital expenditures for older patients with ADRD-HRM, but the prevalence remained low at 14.6% in the study period. Future studies should explore the unmet needs of patients with lower sociodemographic status to increase PC utilization.
