Trends of inpatient palliative care use among hospitalized patients with Parkinson's disease

Approaching neuro-palliative care with historically minoritized groups in the United States: A literature review and actionable recommendations

This review critically examines neuro-palliative care disparities in historically minoritized groups in the U.S., particularly in Asian, Black, and Latino communities. Addressing a gap in the 2022 American Academy of Neurology guidelines, this review synthesizes current literature and our clinical experiences as neurologists who identify as members of these communities in diverse care settings. We identify common barriers to palliative care access and acceptance, influenced by cultural heterogeneity, mistrust, and systemic disparities. The review offers targeted, actionable recommendations at the provider, healthcare system, and policy level to improve care and reduce disparities.

Trends in utilisation of palliative care services in COVID-19 patients and their impact on hospital resources in the USA: insights from the national inpatient sample

OBJECTIVES

Poor prognosis and lack of effective therapeutic options have made palliative care an integral part of the management of severe COVID-19. However, clinical studies on the role of palliative care in severe COVID-19 patients are lacking. The objective of our study was to evaluate the utility of palliative care in intubated COVID-19 patients and its impact on in-hospital outcomes.

METHODS

Rate of palliative care consult, patient-level variables (age, sex, race, income, insurance type), hospital-level variables (region, type, size) and in-hospital outcome variables (mortality, cost, disposition, complications) were recorded.

RESULTS

We retrospectively analysed 263 855 intubated COVID-19 patients using National Inpatient Sample database from 1 January 2020 to 31 December 2020. 65 325 (24.8%) patients received palliative care consult. Factors associated with an increased rate of palliative care consults included: female gender (p<0.001), older age (p<0.001), Caucasian race (p<0.001), high household income (p<0.001), Medicare insurance (p<0.001), admission to large-teaching hospitals (p<0.001), patients with underlying comorbidities, development of in-hospital complications and the need for intensive care procedures. Patients receiving palliative consults had shorter hospital length of stay (LOS) (p<0.001) and no difference in hospitalisation cost (p=0.15).

CONCLUSIONS

Palliative care utilisation rate in intubated COVID-19 patients was reflective of disease severity and disparities in healthcare access. Palliative care may help reduce hospital LOS. Our findings also highlight importance of improving access to palliative care services and its integration into the multidisciplinary management of severe COVID-19 patients.

Naming racism as a root cause of inequities in palliative care research: a scoping review

BACKGROUND

Racial and ethnic inequities in palliative care are well-established. The way researchers design and interpret studies investigating race- and ethnicity-based disparities has future implications on the interventions aimed to reduce these inequities. If racism is not discussed when contextualizing findings, it is less likely to be addressed and inequities will persist.

OBJECTIVE

To summarize the characteristics of 12 years of academic literature that investigates race- or ethnicity-based disparities in palliative care access, outcomes and experiences, and determine the extent to which racism is discussed when interpreting findings.

METHODS

Following Arksey & O'Malley's methodology for scoping reviews, we searched bibliographic databases for primary, peer reviewed studies globally, in all languages, that collected race or ethnicity variables in a palliative care context (January 1, 2011 to October 17, 2023). We recorded study characteristics and categorized citations based on their research focus-whether race or ethnicity were examined as a major focus (analyzed as a primary independent variable or population of interest) or minor focus (analyzed as a secondary variable) of the research purpose, and the interpretation of findings-whether authors directly or indirectly discussed racism when contextualizing the study results.

RESULTS

We identified 3000 citations and included 181 in our review. Of these, most were from the United States (88.95%) and examined race or ethnicity as a major focus (71.27%). When interpreting findings, authors directly named racism in 7.18% of publications. They were more likely to use words closely associated with racism (20.44%) or describe systemic or individual factors (41.44%). Racism was directly named in 33.33% of articles published since 2021 versus 3.92% in the 10 years prior, suggesting it is becoming more common.

CONCLUSION

While the focus on race and ethnicity in palliative care research is increasing, there is room for improvement when acknowledging systemic factors - including racism - during data analysis. Researchers must be purposeful when investigating race and ethnicity, and identify how racism shapes palliative care access, outcomes and experiences of racially and ethnically minoritized patients.

Prevalence of Parkinson's disease among adults aged 45 years and older in China: a cross-sectional study based on the China health and retirement longitudinal study

BACKGROUND

In recent decades, China has experienced a rapid increase in the number of elderly individuals and life expectancy, as well as industrialization, which is associated with an increased prevalence of Parkinson's disease (PD). However, inconsistent results have recently been reported. Therefore, this study aimed to investigate the prevalence and distribution characteristics of PD among individuals aged 45 years and older.

METHODS

Using data from the China Health and Retirement Longitudinal Study (CHARLS), we attempted to estimate the prevalence of PD and its distribution characteristics among 19,034 individuals aged 45 years and older residing in 446 communities/villages within 27 provinces/autonomous regions/municipalities in mainland China. Cases were established based on a doctor's previous diagnosis. Crude and age-adjusted prevalence rates were calculated and stratified by age, sex, area of residence, education level, marital status, and geographic region. Logistic regression models were used to identify risk factors associated with PD.

RESULTS

We identified 178 patients with PD among 19,034 residents aged 45 years and older. The crude prevalence was 0.94%, and the age-adjusted prevalence was 0.82% for individuals aged 45 years and older. The prevalence of PD increased with age (P < 0.001). No significant differences were found in terms of sex, area of residence, or education level. Stratified by geographic region, the prevalence of PD was greater in North and Northwest China and lower in southern China (p < 0.001). Multiple regression analyses showed that age was a significant risk factor for PD.

CONCLUSION

The prevalence of PD increased with age in the Chinese population.

Trends in Specialty Palliative Care Service Utilization and In-Hospital Outcomes for Patients With Amyotrophic Lateral Sclerosis

Background: Hospitalized people with amyotrophic lateral sclerosis (ALS) may benefit from specialty palliative care services (sPCS). Objective: To describe access to in-hospital sPCS for people with ALS (pALS). Methods: We compared years 2010-2011 to 2018-2019, and conducted trend analyses of sPCS from 2010 to 2019 stratified by race. Results: Of 103,193 pALS admitted during the study period, 13,885 (13.4%) received sPCS. Rates of sPCS increased over time (2010-2011: 8.9% vs. 2018-2019: 16.6%; p < 0.01). From 2010 to 2019, there was an increase in sPCS (p-trend<0.01) for all studied racial groups. Conclusions: Access to palliative care has increased over time for pALS admitted to hospitals in the United States.

Gender gap in deep brain stimulation for Parkinson's disease: preliminary results of a retrospective study

Subthalamic nucleus deep brain stimulation (STN-DBS) is an effective treatment of PD for both women and men. However, discussions have been reported about the impact of STN-DBS surgery in PD. The aim of our study is to identify differences between men and women in terms of pre- and post-DBS symptoms and try to explain the possible causes. In the current study, we evaluated the gender impact on STN-DBS in PD at the Department of Neurosurgery of University of Naples "Federico II" from 2013 to 2021. Motor and non-motor symptoms were evaluated. To compare the data before and after surgery and between the genders, Wilcoxon-Mann-Whitney tests were performed. A total of 43 patients with PD were included; of them, 17 (39%) were female. Baseline evaluation revealed no gender differences in the age of onset (p = 0.87). Not significant differences were noted in the Unified Parkinson's Disease Rating Scale (UPDRS) pre-surgery score, but if we consider UPDRS subscores of motor examination, significant clinical improvement was reported in both male and female in terms of UPDRS pre- and post-surgery (p < 0.001). STN-DBS is a highly effective treatment for motor and non-motor symptoms of PD for both women and men but our study hints towards gender-specific outcomes in motor domains. Improving our knowledge in this field can allow us to implement strategies to identify new directions in the development of an adequate treatment of PD in terms of surgical intervention and in consideration of the gender.

Utilization of Palliative Care Services Among Patients With Malignant Brain Tumors: An Analysis of the National Inpatient Sample (2016-2019)

BACKGROUND

Recent advances in treatment of malignant brain tumors have improved outcomes. However, patients continue to experience significant disability. Palliative care helps patients with advanced illnesses improve their quality of life. There is a paucity of clinical studies examining palliative care usage among patients with malignant brain tumors.

OBJECTIVE

To assess if there were any patterns in palliative care utilization among patients hospitalized with malignant brain tumors.

METHODS

A retrospective cohort representing hospitalizations for malignant brain tumors was created from The National Inpatient Sample (2016-2019). Palliative care utilization was identified by ICD-10 code. Univariable and multivariable logistic regression models, accounting for the sample design, were built to evaluate the demographic variables associated with palliative care consultation in all patients and fatal hospitalizations.

RESULTS

375 010 patients admitted with a malignant brain tumor were included in this study. Over the whole cohort, 15.0% of patients used palliative care. In fatal hospitalizations, Black and Hispanic patients had 28% lower odds of receiving a palliative care consultation compared with White patients (odds ratio for both = 0.72; P = .02). For fatal hospitalizations, patients insured privately were 34% more likely to use palliative care services compared with patients insured with Medicare (odds ratio = 1.34, P = .006).

CONCLUSION

Palliative care is underutilized among all patients with malignant brain tumors. Within this population, disparities in utilization are exacerbated by sociodemographic factors. Prospective studies investigating utilization disparities across race and insurance status are necessary to improve access to palliative care services for this population.

Prevalence and Predictors of Palliative Care Utilization among Hospitalized Patients with Diffuse Large B-Cell Lymphoma

Objective: Research has shown that palliative care improves the quality of life of cancer patients; however, there is no literature on specific factors that predict its use in diffuse large b-cell lymphoma (DLBCL) patients. Therefore, the prevalence of palliative care utilization and predictors of palliative care utilization among patients with DLBCL were examined. Methods: Data from the National Inpatient Sample (NIS) collected between 2016 to 2018 were used for all analyses. Multivariable logistic regression models were used to examine the predictors of palliative care utilization among hospitalized patients with DLBCL. Descriptive analyses were used to explore the overall prevalence of palliative care receipt in this population. Results: Of the 41,789 hospitalizations, 7.1% of patients used palliative care during hospitalization, while 4.8% utilized palliative care and were discharged alive. DLBCL patients aged 70 and older had 1.3 times (95% CI: 1.14-1.41) higher odds of utilizing palliative care compared to those less than 70 years. Relative to Medicare/Medicaid patients, those with other types of insurance were 1.7 times (95% CI: 1.34-2.05) more likely to receive palliative care. Those who were either transferred to a facility/discharged with home health (AOR: 6.23; 95% CI: 5.21-7.44) or died during hospitalization (AOR: 45.17; 95% CI: 36.98-55.17) had higher odds of receiving palliative care when relative to those with a routine hospital discharge. Other associated factors were type of admission, length of stay, chemotherapy receipt, and number of comorbidities. Conclusions: The prevalence of palliative care utilization was low and factors predicting utilization in our population were identified. Our findings highlight the need to increase awareness among medical oncologists on the need to involve the palliative care team early in the management of hospitalized patients with DLBCL.

Factors Affecting Hospice Use Among Adolescents and Young Adult Cancer Patients

Background/Objective: Compared to existing studies on end-of-life care of mid- to older-aged patients diagnosed with cancer, there is a paucity of research on adolescents and young adult (AYA) patients. Guided by the Anderson's Behavioral Model for Healthcare Utilization, this study examined predisposing/enabling/need factors associated with hospice referral/enrollment among AYA patients diagnosed with cancer. Methods: Data were drawn from medical records of AYA patients who died of cancer between January 2013 and December 2016 at three academic sites in the United States and were 15-39 years old at the time of death. Logistic regression was conducted (N = 224). Results: Findings showed that hospice referral was strongly associated with hospice enrollment (odds ratio [OR] = 69.68, p < 0.0001). White patients were more likely to be referred to hospice care than non-White patients; the effect was, however, significant only among patients with private insurance (OR = 3.44, p = 0.040). Patients with public insurance were more likely to be referred to hospice than those with private insurance; the effect was, however, significant only among non-White patients (OR = 5.66, p = 0.005). Among those not receiving cancer treatment in the last month of life (LML), patients with hematologic malignancies were less likely to be referred to hospice than those with solid tumors (OR = 0.19). Among patients with solid tumors, receiving cancer treatment in the LML lowered the odds of hospice referral (OR = 0.50, p = 0.043). Conclusion: Further research efforts are needed to investigate the role of race, insurance, cancer types, and treatments in hospice use among bigger samples of AYA patients diagnosed with cancer.

Referral criteria to palliative care for patients with Parkinson's disease: a systematic review

OBJECTIVE

This systematic review aimed to identify the referral criteria for palliative care in patients with Parkinson's disease.

METHODS

We conducted an electronic search for publications on referral criteria for palliative care in patients with Parkinson's disease in six electronic databases. The articles were thoroughly reviewed by two independent reviewers for inclusion using a predefined data extraction list. The referral criteria were thematically classified using a coding methodology.

RESULTS

This systematic review included 36 publications. We identified 14 referral criteria themes. The most common referral indicators were functional decline (n = 11 [31%]), needs assessment tools (n = 11 [31%]), physical or emotional symptoms (n = 10[28%]), need for palliative care (n = 10 [28%]), decision support (n = 9 [25%]), advanced Parkinson's disease (n = 7[19%]), and diagnosis of Parkinson's disease (n = 7 [19%]). However, there was a lack of consensus on symptom assessment tools. In addition, there were no agreed cut-offs or defined time for palliative care referral for patients with Parkinson's disease.

CONCLUSIONS

The 14 themes identified in this systematic review were categorized into disease- and needs-based criteria. These themes show the wide range of referral timing and procedures. Further studies should be conducted to reveal standardized referral criteria.

Trends in Palliative Care Telephone Consultation Support for Health Care Professionals: A Dutch Nationwide Registry between 2004 and 2019

Background: Regional palliative care consultation (PCC) teams aim to support health care professionals by telephone in providing quality palliative care (PC) in the Netherlands. Objectives: The study aims to assess trends in the number and characteristics of PC telephone consultations in the Netherlands between 2004 and 2019. Design: A retrospective observational study reviewed data from the Dutch national register for PC consultations by telephone (PRADO). To assess trends in the number of consultations, three time periods were defined: 2004-2008, 2009-2013, and 2014-2019. All analyses were conducted using STATA. Results: A total of 83,554 PC telephone consultations were analyzed. There was a slight decrease in the number of consultations since 2014, from 5811 (2014) to 4914 (2019). The Dutch PCC telephone helpdesk was mainly consulted by general practitioners, with pharmacological issues (65%) and pain (44%) being the main concerns. The data included 73,833 patients, of whom 63% were 65 years or older (18-109) and 51% were male. The proportion of noncancer patients increased during the selected time periods, 2004-2008 (11%), 2009-2013 (16%), and 2014-2019 (22%). The proportion of consultations requested for hospitalized patients was higher in 2014-2019 (7.9%) than in 2009-2013 (4.5%). Conclusion: Dutch PC telephone consultations have changed over time. More PC telephone consultations were held for hospitalized patients and noncancer diseases over the past years. These trends are in line with the shift toward more integrated PC in which different services collaborate.

Parkinson's disease and Covid-19: Is there an impact of ethnicity and the need for palliative care

Under the traditional models of care for People with Parkinson's Disease (PD, PwP), many of their needs remain unmet and a substantial burden of motor and non-motor symptoms they experience may not be tackled sufficiently. An introduction of palliative care (PC) interventions early in the course of PD offers profound benefits: it may improve quality of life of patients, their families and caregivers through the prevention and relief of medical symptoms, while, at the same time, emphasizing their emotional needs and spiritual wellbeing, establishing goals of care, and engaging in the advance care planning (ACP).

The ongoing Coronavirus Disease 2019 (Covid-19) pandemic poses an unprecedented set of challenges for PwP and has in many ways (both directly and indirectly) magnified their suffering, thus rapidly raising the demand for PC interventions. Covid-19, as well as the repercussions of prolonged mobility restrictions and limited health-care access might exacerbate the severity of PD motor symptoms and interact negatively with a range of non-motor symptoms, with a detrimental effect on quality of life. Greater motor disability, higher amount of levodopa-induced motor fluctuations with an increased daily off-time, fatigue, anxiety, depression, sleep disturbances, pain and worsening of cognitive complaints might dominate the clinical presentation in PwP during the Covid-19 pandemic, alongside raising psychological and spiritual concerns and anticipatory grief.

Here, we aim to provide a foundation for pragmatic and clinically orientated PC approach to improve quality of life and relieve suffering of PwP in the context of the current, ongoing Covid-19 pandemic.

Trends, Sociodemographic and Hospital-Level Factors Associated With Palliative Care Utilization Among Multiple Myeloma Patients Using the National Inpatient Sample (2016-2018)

BACKGROUND

Several factors are reported to be associated with palliative care utilization among patients with various cancers, but literature is lacking on multiple myeloma (MM) specific factors. MM patients have a high symptom burden and early involvement of palliative could increase their quality of life. We examined factors associated with palliative care utilization among MM patients and explored prevalence trends in palliative care utilization among patients with MM.

METHODS

Cross-sectional analyses were conducted using the National Inpatient Sample data collected between 2016 and 2018. Descriptive analyses were used to explore prevalence trends in palliative care utilization over time. Multivariable logistic regression models were used to examine sociodemographic and hospital-level factors associated with palliative care utilization in MM patients.

RESULTS

Overall prevalence of palliative care utilization in our population was 7.7% with a trend of increasing use of palliative care from 7.3% in 2016 to 8.2% in 2018. MM patients aged 70 years and above had 1.30 times higher odds (95% CI: 1.20-1.42) of receiving palliative care relative to those younger than 70 years. Compared to non-Hispanic whites, non-Hispanic blacks (Adjusted odds ratio (AOR): 0.86; 95% CI: 0.79-0.94) were less likely to utilize palliative care. Patients on Medicaid (AOR: 1.27; 95% CI: 1.08-1.49), private insurance (AOR: 1.27; 95% CI: 1.16-1.39) and other insurance types (AOR: 2.10; 95% CI: 1.79-2.47) had significantly higher odds of receiving palliative care when compared to those on Medicare. Other factors identified were hospital region, location, patient disposition, admission type, length of stay, and number of comorbidities.

CONCLUSION

Our findings highlight the urgent need for education of hospital physicians on the need for early palliative care involvement in the care of hospitalized MM patients. Messaging interventions such as the delivery of pop-up messages in electronic medical records to serve as reminders for physicians can be explored as a potential way to increase palliative care consultations for patients who need them.

Protective Effect of Butylphthalide on Neuronal Apoptosis in Parkinson Rats and Its Effect on miR-146a-5p Expression and Phosphatidylinositide 3-Kinases/Protein Kinase B Pathway

80 male Wistar rats were stochastically assigned to Sham + Vehicle group, Sham + BUT group, PD + Vehicle group and PD + BUT group. Rotenone PD model rats were prepared by subcutaneous injection of rotenone sunflower oil emulsion 2 mg/(kg · d) for 5 consecutive weeks. Butylphthalide 80 mg/(kg · d) were given to the rats in Sham + BUT group and PD + BUT group by gavage from the first day of rotenone injection for 5 weeks. Subsequently, the motor retardation ability and the morphological changes of the substantia nigra (SN) of each group were evaluated. Meanwhile, the levels of neuronal injury, apoptosis, inflammation and oxidative stress in each group of rats were assayed. The impact of BUT treatment on miR-146a-5p expression and PI3K/AKT signal pathway in rat brain tissue was assayed. Finally, by constructing a PD cell model of the neurotoxin 6-hydroxydopamine (6-OHDA)-treated human neuroblastoma cell line SH-SY5Y, the in vitro anti-PD pharmacological effect of BUT was further verified.

Disparities in Palliative and Hospice Care and Completion of Advance Care Planning and Directives Among Non-Hispanic Blacks: A Scoping Review of Recent Literature

OBJECTIVES

Published research in disparities in advance care planning, palliative, and end-of-life care is limited. However, available data points to significant barriers to palliative and end-of-life care among minority adults. The main objective of this scoping review was to summarize the current published research and literature on disparities in palliative and hospice care and completion of advance care planning and directives among non-Hispanc Blacks.

METHODS

The scoping review method was used because currently published research in disparities in palliative and hospice cares as well as advance care planning are limited. Nine electronic databases and websites were searched to identify English-language peer-reviewed publications published within last 20 years. A total of 147 studies that addressed palliative care, hospice care, and advance care planning and included non-Hispanic Blacks were incorporated in this study. The literature review include manuscripts that discuss the intersection of social determinants of health and end-of-life care for non-Hispanic Blacks. We examined the potential role and impact of several factors, including knowledge regarding palliative and hospice care; healthcare literacy; communication with providers and family; perceived or experienced discrimination with healthcare systems; mistrust in healthcare providers; health care coverage, religious-related activities and beliefs on palliative and hospice care utilization and completion of advance directives among non-Hispanic Blacks.

DISCUSSION

Cross-sectional and longitudinal national surveys, as well as local community- and clinic-based data, unequivocally point to major disparities in palliative and hospice care in the United States. Results suggest that national and community-based, multi-faceted, multi-disciplinary, theoretical-based, resourceful, culturally-sensitive interventions are urgently needed. A number of practical investigational interventions are offered. Additionally, we identify several research questions which need to be addressed in future research.

Trends in inpatient palliative care use for primary brain malignancies

INTRODUCTION

Primary brain malignancies (PBMs) pose significant morbidity and poor prognosis. Despite NCCN recommendations that palliative care should be integrated into general oncologic care plans, it has been historically underused in patients with PBM. We sought to examine trends and factors associated with inpatient palliative care use in patients with PBM.

METHODS

Data from the 2007-2016 National (Nationwide) Inpatient Sample was analyzed for descriptive statistics and trends. Multivariable logistic regression was used to identify factors associated with inpatient palliative care in patients with PBMs.

RESULTS

Of the 510,238 observed hospitalizations of adults with PBM in a 10-year period, 37,365 (7.3%) had an associated inpatient palliative care consult. Rates of inpatient palliative care have increased significantly over the 10-year period, from 2.3 in 2007 to 11.9% in 2011. Patients receiving inpatient palliative care were less likely to receive inpatient oncologic treatment such as brain surgery, chemotherapy, or radiation compared to those without palliative care (14.6% with palliative care vs. 42.4% without, p < 0.001). They were more likely to receive life-sustaining treatments such as intubation, mechanical ventilation, tracheostomy, nutritional support, hemodialysis, or CPR (21.0% with palliative care vs. 10.4% without, p < 0.001). Palliative care was associated with decreased cost of admission ($18,602 with palliative care vs. $20,077 without). In a multiple variable logistic regression, age, non-elective admission, comorbidities, history of chemotherapy and radiation, and mechanical ventilation were associated with significantly increased odds of receiving palliative care.

CONCLUSIONS

Inpatient palliative care utilization for patients hospitalized with PBM significantly increased between 2007 and 2016, though the service is still underutilized in the context of the severe symptoms and poor prognosis associated with PBM.
