Characteristics and Outcomes of Dementia Patients Who Receive Inpatient Palliative Care Consultation

Palliative Care in Early Dementia

BACKGROUND

Palliative care is recommended for all people with dementia from diagnosis through end-of-life. However, palliative care needs and effective elements of palliative care are not well-defined for the earlier stages of dementia.

OBJECTIVE

To systematically map current research on palliative care early in the disease trajectory of dementia.

DESIGN

Scoping review of scientific literature.

DATA SOURCES

PubMed, CINAHL, EMBASE, Cochrane, PsycINFO, Web of Science.

REVIEW METHODS

We included studies published in English over the last decade (through March 2022) that focused on palliative care in early stages of dementia and targeted outcomes in palliative care domains. Two authors independently screened abstracts and full texts and scored the quality of included studies using tools by the Joanna Briggs Institute.

RESULTS

Among the 77 papers reviewed, few addressed early stages of dementia specifically. We found that: 1) While "early" palliative care was not well-defined in the literature, evidence indicated that palliative care needs were present at or before diagnosis and across the trajectory. Notable opportunities for palliative care arise at 'tipping points' (i.e., when symptoms, functional status, or caregiving needs change). 2) Palliative care needs in early dementia include advocacy for goal-aligned care in the future, reassurance against the threat of negligence and abandonment by caregivers, planning for future scenarios of care (practical, individual, and relational needs), and establishing of long-term relationships with providers entrusted for care later in disease. 3) Elements of effective palliative care in early dementia could include dementia-specific ACP and goals of care discussions, navigation for building a network of support, provision of tools and resources for family, tailored care and knowledge of the person, and well-prepared dementia-care providers. The scarcity of palliative care studies aimed at early disease indicates a gap in the evidence in dementia care.

CONCLUSION

The literature on palliative care in early dementia is sparse. Future studies should focus on assessment tools for optimizing timing of palliative care in early dementia, gaining better understanding of patient and family needs during early phases of disease, and providing training for providers and families in long-term relationships and communication around goals of care and future planning.

Factors Associated with Costly Hospital Care among Patients with Dementia and Acute Respiratory Failure

Rationale: Understanding contributors to costly and potentially burdensome care for patients with dementia is of interest to healthcare systems and may facilitate efforts to promote goal-concordant care. Objective: To identify risk factors, in particular whether an early goals-of-care discussion (GOCD) took place, for high-cost hospitalization among patients with dementia and acute respiratory failure. Methods: We conducted an electronic health record-based retrospective cohort study of 298 adults with dementia hospitalized with respiratory failure (receiving ⩾48 h of mechanical ventilation) within an academic healthcare system. We collected demographic and clinical characteristics, including clinical markers of advanced dementia (weight loss, pressure ulcers, hypernatremia, mobility limitations) and intensive care unit (ICU) service (medical, surgical, neurologic). We ascertained whether a GOCD was documented within 48 hours of ICU admission. We used logistic regression to identify patient characteristics associated with high-cost hospitalization measured using the hospital system accounting database and defined as total cost in the top third of the sample (⩾$145,000). We examined a path model that included hospital length of stay as a final mediator between exposure variables and high-cost hospitalization. Results: Patients in the sample had a median age of 71 (IQR, 62-79) years. Approximately half (49%) were admitted to a medical ICU, 29% to a surgical ICU, and 22% to a neurologic ICU. More than half (59%) had a clinical indicator of advanced dementia. A minority (31%) had a GOCD documented within 48 hours of ICU admission; those who did had a 50% lower risk of a high-cost hospitalization (risk ratio, 0.50; 95% confidence interval, 0.2-0.8). Older age, limited English proficiency, and nursing home residence were associated with a lower likelihood of high-cost hospitalization, whereas greater comorbidity burden and admission to a surgical or neurologic ICU compared with a medical ICU were associated with a higher likelihood of high-cost hospitalization. Conclusions: Early GOCDs for patients with dementia and respiratory failure may promote high-value care by ensuring aggressive and costly life support interventions are aligned with patients' goals. Future work should focus on increasing early palliative care delivery for patients with dementia and respiratory failure, in particular in surgical and neurologic ICU settings.

Inpatient Palliative Care and Healthcare Utilization Among Older Patients With Alzheimer's Disease and Related Dementia (ADRD) and High Risk of Mortality in U.S. Hospitals

Background. 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). Methods. 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). Results. 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). Conclusions. 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 and those in rural hospitals to further increase their PC consultation utilization.

Mechanical Ventilation in Older Adults With Dementia: Opportunities to Promote Goal-Concordant Care

CONTEXT

Recent studies show increasing use of mechanical ventilation among people living with dementia. There are concerns that this trend may not be driven by patient preferences.

OBJECTIVES

To better understand decision-making regarding mechanical ventilation in people living with dementia.

METHODS

This was an electronic health record-based retrospective cohort study of older adults with dementia (n = 295) hospitalized at one of two teaching hospitals between 2015 and 2019 who were supported with mechanical ventilation (n = 191) or died without mechanical ventilation (n = 104). Multivariable logistic regression was used to examine associations between patient characteristics and mechanical ventilation use.

RESULTS

The median age was 78 years (IQR 71-86), 41% were female, 28% resided in a nursing home, and 58% had clinical markers of advanced dementia (dehydration, weight loss, mobility limitations, or pressure ulcers). Among patients supported with mechanical ventilation, 70% were intubated within 24 hours of presentation, including 31% intubated before hospital arrival. Younger age, higher illness acuity, and absence of a treatment-limiting Physician Orders for Life-Sustaining Treatment document were associated with mechanical ventilation use; nursing home residence and clinical markers of advanced dementia were not. Most patients (89%) had a documented goals of care discussion (GOCD) during hospitalization.

CONCLUSION

Future efforts to promote goal-concordant care surrounding mechanical ventilation use for people living with dementia should involve identifying barriers to goal-concordant care in pre-hospital settings, assessing the timeliness of in-hospital GOCD, and developing strategies for in-the-moment crisis communication across settings.
