Palliative care for Parkinson's disease: a summary of the evidence and future directions

Understanding Psychosocial Functioning, Caregiver Burden, and Neuropalliative Care in Parkinson's Disease - A Mixed-Methods Study

BACKGROUND

Despite advancements in treatment, patients with Parkinson's disease (PD) experience a range of symptoms that affect their quality of life. There is a need to integrate neuropalliative care into standard care. The aim of the study is to understand the psychosocial functioning in persons with PD and explore their caregivers' burden.

METHODS

The study utilizes a mixed-methods design where 50 patient-caregiver dyads attending the outpatient services of the movement disorder clinic at a tertiary care hospital were measured on psychosocial functioning and caregiver burden and palliative care outcomes for a period of 6 months. Focus group discussions were conducted with 18 patient-caregiver dyads to understand the needs of palliative care.

RESULTS

It was found that caregiver burden was positively correlated with palliative care outcomes scores of patients ( r = 0.586) and caregivers ( r = 0.675) and psychosocial functioning was positively correlated with palliative care outcomes of patients ( r = 0.708). The psychosocial functioning score was higher among female patients (indicating worse functioning) than males, and female caregivers experienced significantly higher caregiver burden. The qualitative findings reveal that there is a substantial gap in awareness about palliative care, lack of information, presence of stigmatizing beliefs, and lack of adequate accessibility to palliative facilities.

CONCLUSION

The study lays the foundation for future PD neuropalliative care research, guiding interventions, and exploration of regional variations in PD experiences in India. There is a need to address caregiver burden in PD in India.

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.

Pain, physical symptoms and functional assessment in progressive neurological disease in palliative care

OBJECTIVES

The aim of the research was to identify the most frequent symptoms of patients with progressive neurological disease (PND) in relation to their functional state. Another objective was to determine the effects of consultations with a multidisciplinary palliative team on mitigating the symptoms burden, subjective evaluation of health, disease progression and improvement of the functional state.

METHODS

The interventional control study included 151 patients with PND (98 patients in the intervention group, 53 patients in the control group). The intervention group was provided with consultations of a multidisciplinary palliative team. The symptoms scale of the progressive neurological diseases quality of life was used to collect data. The patients completed the questionnaire before the provided intervention and 3 months after that.

RESULTS

Pain and fatigue were identified as the symptoms that trouble the patients the most. After the intervention, there was a determined statistically significant improvement in the evaluation of 9 out of 11 symptoms (except excretion and urination) among the patients from the intervention group compared with the control group. When assessed again, the patients from the intervention group showed an improvement with respect to six symptoms (pain, fatigue, tremor, stiffness, cramps, excretion), while the patients from the control group had six symptoms that deteriorated (drowsiness, dyspnoea, stiffness, swallowing, salivation, excretion). There was not any confirmed positive impact of the intervention on the cognitive functions of the patients.

CONCLUSION

The provision of consultations with the multidisciplinary palliative team to patients with PND in an advanced stage of disease resulted in decreasing their symptoms burden and improving their functional state.

End of life care of hospitalized patients with Parkinson disease: a retrospective analysis and brief review

Background

Towards the end of life (EOL), persons with parkinsonism (PwP) have complex needs and can present with unique palliative care (PC) challenges. There are no widely accepted guidelines to aid neurologists, hospitalists, or PC clinicians in managing the symptoms of PwP at EOL. We examined a population of PwP at EOL, aiming to describe trends of in-hospital management and utilization of PC services.

Methods

All PwP admitted to two hospitals during 2018 (N = 727) were examined retrospectively, assessing those who died in hospital or were discharged with hospice (EOL group, N = 35) and comparing them to the main cohort. Their demographics, clinical data, engagement of multidisciplinary and palliative services, code status changes, invasive care, frequency of admissions, and medication administration were assessed.

Results

Among the EOL group, 8 expired in hospital, and 27 were discharged to hospice. Forty-six percent of EOL patients received a PC consultation during their admission. The median interval from admission to death was 37 days. Seventy-seven percent had a full code status on admission. Compared to hospice patients, those who expired in hospital had higher rates of invasive procedures and intensive care unit transfers (41% vs. 75%, in both variables), and lower rates of PC involvement (52% vs. 25%). The transition of code status change for the EOL group from Full code to Do Not Resuscitate (DNR) occurred at a median 4-5 days from admission. For patients that passed in the hospital, the median days from transition of code status to death was 0(IQR 0-1). Levodopa dose deviations were frequent in both EOL and non-EOL group, but contraindicated medications were infrequently administered (11% in EOL group vs. 9% in non-EOL group).

Conclusion

Our data suggest a low utilization of PC services and delayed discussions of goals of care. More work is needed to raise awareness of inpatient teams managing PwP regarding the unique but common challenges facing PwP with advanced disease. A brief narrative review summarizing the suggested management of symptoms common to hospitalized PwP near EOL is provided.

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.

The Effect of a Multidisciplinary Blended Learning Program on Palliative Care Knowledge for Health Care Professionals Involved in the Care for People with Parkinson's Disease

BACKGROUND

Parkinson's disease (PD) is an increasingly prevalent and progressive degenerative disease. Palliative care for PD should be integrated into the routine care for people with PD. However, PD health care professionals typically lack knowledge of palliative care, highlighting the necessity of educational programs in this field.

OBJECTIVE

To determine the effectiveness of a multidisciplinary blended learning program for health care professionals specialized in PD in the Netherlands.

METHODS

We used a pre-posttest intervention design. The intervention consisted of an e-learning in combination with an online network meeting in which the participating health care professionals discussed palliative care for PD with specialists from the field of palliative care. Outcome variables included self-rated level of knowledge (scale 1-10), familiarity with specialized palliative care services (5-point Likert scale) and the validated End-of-Life Professional Caregiver Survey (EPCS).

RESULTS

A total of 1029 participants from sixteen different disciplines, all active in the care for people with PD, with a mean age of 45 years and 13 years of working experience, followed the blended learning program. Self-rated level of knowledge improved from 4.75 to 5.72 (0.96; p < 0.001; 95% CI change = [0.85 . . . 1.08]. Familiarity with palliative care services also increased by 1.06 (from 1.85 to 2.90; p=<0.001; 95% CI change = [1.00 . . . 1.12]).

CONCLUSION

A blended learning program can improve self-rated knowledge about palliative care and its services. Such programs might be a first step towards optimal integration of palliative care expertise and services within PD-care.

Parkinson's disease - palliative care needs assessment tool: adaptation and psychometric testing

OBJECTIVE

Parkinson's disease is a progressive, life-limiting disease, which benefits from structured palliative care. Systematic recognition and triage of needs helps facilitate care, allows focused referral to specialist palliative care and aids sustainability of services. Existing palliative care tools for Parkinson's are patient/caregiver completed and focus on quantification rather than identification of the need. The Needs Assessment Tool: Progressive Disease in Cancer was designed for rapid identification of unmet needs in cancer. We describe adaptation and psychometric testing of the tool for Parkinson's disease (NAT:Parkinson's disease).

METHODS

Set in secondary care, Parkinson's disease outpatient clinics in the UK, this study included people with Parkinson's, age >18, including all disease stages. People with atypical Parkinsonian syndromes were excluded. Adaptation was made using systematic review and focus groups. Construct validity was tested in 50 consecutive patients against established patient and caregiver measures, analysed with Kendall's Tau B. Inter-rater reliability, using video consultations, were calculated in broad range of clinicians involved in Parkinson's disease care using a weighted kappa; 0-0.2=slight, 0.21-0.40=fair, 0.41-0.60=moderate, 0.61-0.80=substantial and p<0.05 indicative of statistically significant agreement.

RESULTS

Validity was substantial for two, moderate for five and fair for four constructs. Inter-rater reliability was substantial for one, moderate for three and fair for six constructs. Two constructs failing to demonstrate fair reliability did show very high percentage agreement.

CONCLUSION

Findings support the suitability of the NAT:Parkinson's disease for everyday clinical use in the identification and triage of unmet palliative need for people with Parkinson's disease.

Using the Concept of Health Literacy to Understand How People Living with Motor Neurone Disease and Carers Engage in Healthcare: A Longitudinal Qualitative Study

The growing body of information-seeking and decision-making literature in motor neurone disease (MND) has not yet explored the impact of health literacy. Health literacy relates to the skills people have to access, understand, and use health information and is influenced by motivation to engage with healthcare. We aimed to better understand how people affected by MND engage in healthcare by examining longitudinal interview data using the construct of health literacy. Semi-structured interviews were conducted with 19 persons living with MND and 15 carers recruited from a specialist MND clinic using maximum variation sampling. Transcripts were deductively coded using a framework of health literacy behaviours. The analysis used a matrix-based approach for thematic analysis of longitudinal data. People living with MND and carers sought nuanced information dependent on their priorities and attitudes. Information uptake was influenced by perceived relevancy and changed over time. Time allowed opportunity to reflect on and understand the significance of information provided. The findings indicate that persons living with MND and carers benefit when information and consultations are adapted to meet their communication needs. The results highlight the potential benefits of gaining an early understanding of and accommodating the communication needs, personal preferences, and emotional readiness for information for persons living with MND and their carers.

Triggers for Referral to Specialized Palliative Care in Advanced Neurologic and Neurosurgical Conditions: A Systematic Review

Background and Objectives

To systematically review the literature for the most suitable trigger criteria for referral to specialist palliative care services in life-limiting and life-threatening neurologic and neurosurgical conditions.

Methods

Literature searches were conducted in Ovid MEDLINE and EMBASE (1990-December 2020). To be included, studies must have trigger/referral criteria clearly outlined, a ≥75% nononcology neurosciences population, and consensus or guidelines documents regarding palliative neurosciences or trigger/referral criteria. We excluded studies that had an oncologic or non-neurosciences population as the main focus of study, trigger and referral criteria not clearly outlined, and no primary or duplicative data. The protocol was registered with PROSPERO (CRD4202013579), and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. The American Academy of Neurology Clinical Practice Guidelines Process Manual was used to assess for risk of bias.

Results

Our search identified 1,748 publications, of which 22 articles met the eligibility criteria. Studies were considered in 2 main groups: (A) studies designed specifically to identify trigger criteria for referral to specialized neuropalliative care services (n = 9) and (B) studies that retrospectively reported the reason for referral to specialized palliative care or reflected a consensus statement among people with advanced neurologic illness (n = 13). Overall, the results suggest that several published referral triggers for specialized neuropalliative care are based on expert consensus. However, there is a growing body of literature providing evidence-based condition-specific triggers for multiple sclerosis, parkinsonism, amyotrophic lateral sclerosis, and dementia.

Discussion

There is a growing body of research that outlines evidence-based referral triggers for neuropalliative care. The ambiguity of nomenclature surrounding referral triggers in the current literature and field of neuropalliative care was a limitation to this study. We suggest that condition-specific triggers are likely to be the most effective for identifying the appropriate patients and timing for referral to specialist palliative care. (PROSPERO registration number: CRD42020135791, crd.york.ac.uk/prospero).

When to initiate palliative care in neurology

Life-limiting and life-threatening neurologic conditions often progress slowly. Patients live with a substantial symptom burden over a long period of time, and there is often a high degree of functional and cognitive impairment. Because of this, the most appropriate time to initiate neuropalliative care is often difficult to identify. Further challenges to the incorporation of neuropalliative care include communication barriers, such as profound dysarthria or language impairments, and loss of cognitive function and decision-making capacity that prevent shared decision making and threaten patient autonomy. As a result, earlier initiation of at least some components of palliative care is paramount to ensuring patient-centered care while the patient is still able to communicate effectively and participate as fully as possible in their medical care. For these reasons, neuropalliative care is also distinct from palliative care in oncology, and there is a growing evidence base to guide timely initiation and integration of neuropalliative care. In this chapter, we will focus on when to initiate palliative care in patients with life-limiting, life-threatening, and advanced neurologic conditions. We will address three main questions, which patients with neurologic conditions will benefit from initiation of palliative care, what aspects of neurologic illness are most amenable to neuropalliative care, and when to initiate neuropalliative care?

Dying with Parkinson's Disease: Healthcare Utilization and Costs in the Last Year of Life

BACKGROUND

The end-of-life period is associated with disproportionately higher health care utilization and cost at the population level but there is little data in Parkinson's disease (PD).

OBJECTIVE

The goals of this study were to 1) compare health care use and associated cost in the last year of life between decedents with and without PD, and 2) identify factors associated with palliative care consultation and death in hospital.

METHODS

Using linked administrative datasets held at ICES, we conducted a retrospective, population-based cohort study of all Ontario, Canada decedents from 2015 to 2017. We examined demographic data, rate of utilization across healthcare sectors, and cost of health care services in the last year of life.

RESULTS

We identified 291,276 decedents of whom 12,440 (4.3%) had a diagnosis of PD. Compared to decedents without PD, decedents with PD were more likely to be admitted to long-term care (52% vs. 23%, p < 0.001) and received more home care (69.0 vs. 41.8 days, p < 0.001). Receipt of palliative homecare or physician palliative home consultation were associated with lower odds of dying in hospital (OR: 0.24, 95% CI: 0.19- 0.30, and OR: 0.38, 95% CI: 0.33- 0.43, respectively). Mean cost of care in the last year of life was greater for decedents with PD ($68,391 vs. $59,244, p < 0.001).

CONCLUSION

Compared to individuals without PD, individuals with PD have higher rates of long-term care, home care and higher health care costs in the last year of life. Palliative care is associated with a lower rate of hospital death.

Barriers to Accessing Healthcare Services for People with Parkinson's Disease: A Scoping Review

Parkinson's disease is a complex condition that affects many different aspects of a person's health. Because of its complexity, people with Parkinson's disease require access to a variety of healthcare services. The aim of the present study was to identify the barriers to access healthcare services for people with Parkinson's disease. We conducted a scoping review according to guidelines posed by Arksey & O'Malley (2005). A search of MEDLINE, Embase, CINHAL, and PsycINFO databases was conducted, and 38 articles were selected based on the inclusion criteria. The review findings identified person-level and system-level barriers. The person-level barriers included skills required to seek healthcare services, ability to engage in healthcare and cost for services. The system-level barriers included the availability of appropriate healthcare resources. Based on the existing barriers elucidated in the scope review, we have discussed potential areas in healthcare that require improvement for people with Parkinson's disease to manage their healthcare needs more equitably.

"No One Can Tell Me How Parkinson's Disease Will Unfold": A Mixed Methods Case Study on Palliative Care for People with Parkinson's Disease and Their Family Caregivers

Background:

Palliative care for persons with Parkinson’s disease (PD) is developing. However, little is known about the experiences of patients with PD in the palliative phase and of their family caregivers.

Objective:

To explore needs of patients with PD in the palliative phase and of their family caregivers.

Methods:

A mixed methods case study design. Health care professionals included patients for whom the answer on the question “Would you be surprised if this patient died in the next 12 months?” was negative. At baseline, and after six and twelve months, we conducted semi-structured interviews with patients and caregivers. Participants completed questionnaires on quality of life, disease burden, caregiver burden, grief, and positive aspects of caregiving. We analyzed quantitative data using descriptive statistics, while we used thematic analysis for qualitative data.

Results:

Ten patients and eight family caregivers participated, of whom five patients died during the study period. While the quantitative data reflected a moderate disease burden, the qualitative findings indicated a higher disease burden. Longitudinal results showed small differences and changes in time. Patients reported a diverse range of symptoms, such as fatigue, immobility, cognitive changes, and hallucinations, which had a tremendous impact on their lives. Nevertheless, they rated their overall quality of life as moderate to positive. Family caregivers gradually learned to cope with difficult situations such delirium, fluctuations in functioning and hallucinations. They had great expertise in caring for the person with PD but did not automatically share this with health care professionals. Patients sensed a lack of time to discuss their complex needs with clinicians. Furthermore, palliative care was rarely discussed, and none of these patients had been referred to specialist palliative care services.

Conclusion:

Patients with PD experienced many difficulties in daily living. Patients seems to adapt to living with PD as they rated their quality of life as moderate to positive. Family caregivers became experts in the care for their loved one, but often learned on their own. An early implementation of the palliative care approach can be beneficial in addressing the needs of patients with PD and their family caregivers.

Advance Care Planning and Care Coordination for People With Parkinson's Disease and Their Family Caregivers-Study Protocol for a Multicentre, Randomized Controlled Trial

Background: Parkinson's disease (PD) is a progressive neurodegenerative disease with motor- and non-motor symptoms. When the disease progresses, symptom burden increases. Consequently, additional care demands develop, the complexity of treatment increases, and the patient's quality of life is progressively threatened. To address these challenges, there is growing awareness of the potential benefits of palliative care for people with PD. This includes communication about end-of-life issues, such as Advance Care Planning (ACP), which helps to elicit patient's needs and preferences on issues related to future treatment and care. In this study, we will assess the impact and feasibility of a nurse-led palliative care intervention for people with PD across diverse European care settings.

Methods: The intervention will be evaluated in a multicentre, open-label randomized controlled trial, with a parallel group design in seven European countries (Austria, Estonia, Germany, Greece, Italy, Sweden and United Kingdom). The “PD_Pal intervention” comprises (1) several consultations with a trained nurse who will perform ACP conversations and support care coordination and (2) use of a patient-directed “Parkinson Support Plan-workbook”. The primary endpoint is defined as the percentage of participants with documented ACP-decisions assessed at 6 months after baseline (t1). Secondary endpoints include patients' and family caregivers' quality of life, perceived care coordination, patients' symptom burden, and cost-effectiveness. In parallel, we will perform a process evaluation, to understand the feasibility of the intervention. Assessments are scheduled at baseline (t0), 6 months (t1), and 12 months (t2). Statistical analysis will be performed by means of Mantel–Haenszel methods and multilevel logistic regression models, correcting for multiple testing.

Discussion: This study will contribute to the current knowledge gap on the application of palliative care interventions for people with Parkinson's disease aimed at ameliorating quality of life and managing end-of-life perspectives. Studying the impact and feasibility of the intervention in seven European countries, each with their own cultural and organisational characteristics, will allow us to create a broad perspective on palliative care interventions for people with Parkinson's disease across settings.

Understanding how people with Parkinson's disease and their relatives approach advance care planning

PURPOSE

Advance care planning gives individuals with capacity the option of planning for their future, and anticipating future decision-making about their treatment or care should they then lose capacity. People with Parkinson's disease (PD) may develop significant physical and cognitive problems as the disease progresses, which creates a great need for, but significant challenges to, advance care planning. As a result, we set out to explore the views of people with PD and relatives on planning for the future and advance care planning.

METHODS

Qualitative study with semi-structured interviews of thirty-three people with PD and their relatives in the North-East of England.

RESULTS

Interviewees with PD were generally not keen to engage with advance care planning in the present, in comparison to the future. Three main themes arose from the data in identifying why this may be the case: (1) 'Awareness'-which included the limited awareness on purpose of advance care planning and Parkinson's disease; (2) 'Uncertainty'-the uncertainty of living with PD and of life; and (3) 'Salience'-the complex decision-making processes that interviewees engaged in, which were highly variable.

CONCLUSION

The use of advance care planning in PD is influenced by its perception amongst people with PD and their relatives. Health professionals have an important role in raising the salience of health care planning.

Preferences for Communication About End-of-Life Care in Atypical Parkinsonism

BACKGROUND

Studies on preferences regarding discussions on end-of-life care (EOLC), advance care planning (ACP), medical assistance in dying (MAiD), and brain donation have not yet been conducted in patients with atypical parkinsonism (AP).

OBJECTIVE

The aim of this study was to know the preferences of patients with AP regarding discussions on EOLC, ACP, MAiD, and brain donation.

METHODS

This cross-sectional study was conducted in patients clinically diagnosed with AP. An adapted questionnaire that assessed various potential factors that affect patients' preferences regarding EOLC and ACP was sent through postal mail to 278 patients.

RESULTS

A total of 90 completed questionnaires were returned. Most patients preferred to discuss at the time of diagnosis information about the disease, its natural course, treatment options, and prognosis. In contrast, they preferred that EOLC and ACP be discussed when the disease has progressed. No demographic or disease-related factors were found to be predictors of the patient's preferences. Notably, most patients (63.3%) had previous actual discussions on these issues. Less than a third of patients were open to discussions about MAiD and brain donation; older age and the importance of spirituality and religion decreased the odds of discussing these.

CONCLUSIONS

Our study demonstrates that patients with AP have preferences regarding the timing of the discussion of the different themes surrounding EOLC and ACP. A needs-based approach in initiating and conducting timely discussions on these difficult but essential issues is proposed. A thorough explanation and recognition of a patient's beliefs are recommended when initiating conversations about MAiD and brain donation. © 2021 International Parkinson and Movement Disorder Society.

Prognostic predictors relevant to end-of-life palliative care in Parkinson's disease and related disorders: a systematic review

Parkinson's disease and related disorders (PDRD) are the second most common neurodegenerative disease and a leading cause of death. However, patients with PDRD receive less end-of-life palliative care (hospice) than other illnesses, including other neurologic illnesses. Identification of predictors of PDRD mortality may aid in increasing appropriate and timely referrals. To systematically review the literature for causes of death and predictors of mortality in PDRD to provide guidance regarding hospice/end-of-life palliative care referrals. We searched MEDLINE, PubMed, EMBASE and CINAHL databases (1970-2020) of original quantitative research using patient-level, provider-level or caregiver-level data from medical records, administrative data or survey responses associated with mortality, prognosis or cause of death in PDRD. Findings were reviewed by an International Working Group on PD and Palliative Care supported by the Parkinson's Foundation. Of 1183 research articles, 42 studies met our inclusion criteria. We found four main domains of factors associated with mortality in PDRD: (1) demographic and clinical markers (age, sex, body mass index and comorbid illnesses), (2) motor dysfunction and global disability, (3) falls and infections and (4) non-motor symptoms. We provide suggestions for consideration of timing of hospice/end-of-life palliative care referrals. Several clinical features of advancing disease may be useful in triggering end-of-life palliative/hospice referral. Prognostic studies focused on identifying when people with PDRD are nearing their final months of life are limited. There is further need for research in this area as well as policies that support need-based palliative care for the duration of PDRD.

Symptom Burden and Unmet Support Needs of Patients With Parkinson's Disease: A Cross-Sectional Study in Asia-Pacific Regions

OBJECTIVES

Support care is rarely assessed and offered to people with long-term neurologic conditions, particularly Parkinson's disease. This study aimed to assess the symptom burden and unmet support care needs in people with mild to severe Parkinson's disease.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

Patients with Parkinson's disease were recruited from neurologic outpatient clinics from 3 East and Southeast Asian regions, including Hong Kong, Taiwan, and Thailand.

METHODS

A standardized set of questionnaires assessing unmet care needs [Palliative care Outcome Scale (POS)], disease-specific symptom burden (POS-Symptoms-Parkinson's Disease), generic health-related quality of life (HRQOL) (EQ-5D-3L), and sociodemographic and clinical background.

RESULTS

Completed questionnaires (n = 186) were collected from 64 Hong Kong Chinese, 64 Taiwanese, and 58 Thai patients. Their mean age was 67.23 ± 8.07, 54% were female, and 80% had mild-to-moderate disease. Their mean POS score was 10.48 ± 6.38, indicating moderate unmet support needs. Two-thirds of the participants rated constipation, fatigue, leg problem, and daytime somnolence as the most prevalent and burdensome symptoms. Patients from Hong Kong and Taiwan prioritized psychosocial and spiritual support, whereas Thai patients prioritized physical needs and emotional concerns. Multivariate adjustment for demographics and clinical characteristics showed that high psychological, spiritual, and practical burdens are associated with young age, male gender, and advanced disease stages.

CONCLUSIONS AND IMPLICATIONS

Patients experience significant symptom burden and moderate unmet support needs at the early to middle stage of Parkinson's disease. Routine assessment of changes in symptom burden should start early. The timely referral of support care services should provide appropriate psychospiritual and practical support in addition to motor training. Planning for support care services should consider cultural and health service contexts.

Experiences of advance care planning in Parkinson's disease and atypical parkinsonian disorders: a mixed methods systematic review

BACKGROUND AND PURPOSE

Advance care planning allows people to plan for their future care needs and can include medical, psychological and social aspects. However, little is known on the use, experience of and attitudes towards advance care planning in patients with parkinsonian disorders, their family carers and healthcare professionals.

METHODS

A systematic search of online databases was conducted in April 2019 using a narrative synthesis approach with thematic analysis and tabulation to synthesize the findings.

RESULTS

In all, 507 articles were identified and 27 were included. There were five overarching themes: (i) what is involved in advance care planning discussions, (ii) when and how advance care planning discussions are initiated, (iii) barriers to advance care planning, (iv) the role of healthcare professionals and (v) the role of the family carer. This evidence was used to highlight eight effective components to support optimal advance care planning in parkinsonian disorders: advance care planning discussions should be individualized in content, timing and approach; patients should be invited to discuss advance care planning early and regularly; palliative care services should be introduced early; a skilled professional should deliver advance care planning; support to family carers should be offered in the advance care planning process; healthcare professionals should be educated on parkinsonian disorders and palliative care; advance care planning should be clearly documented and shared with relevant services; and healthcare professionals should be enabled to conduct effective advance care planning.

CONCLUSIONS

These components can inform best practice in advance care planning in patients with parkinsonian disorders.

"How Long Can I Carry On?" The Need for Palliative Care in Parkinson's Disease: A Qualitative Study from the Perspective of Bereaved Family Caregivers

Background:

Family caregivers provide the majority of care for people with Parkinson’s disease (PD) in the palliative care phase. For many this is a demanding experience, affecting their quality of life.

Objective:

We set out to map the experiences of bereaved family caregivers during the period of informal care in the palliative care phase as well as after the death of their loved one with PD.

Methods:

Ten bereaved family caregivers participated in this qualitative study. Semi-structured interviews were conducted and interpretative phenomenological analysis was used executed.

Results:

We identified four main themes. 1) Feeling like a professional caregiver: while caring for a person with PD, the family caregivers took over many roles and tasks of the person with PD. 2) Healthcare professionals do not always know what PD really means: most interviewees had negative experiences with knowledge and understanding of PD of, especially, (practice) nurses. 3) Being on your own: many respondents had felt highly responsible for their loved one’s care and lacked time and space for themselves. Grief and feelings of guilt were present during the caregiving period and after death. 4) Being behind the times: to provide palliative care in line with patients’ preferences and to feel prepared for the palliative care phase of PD, proactive palliative care planning was considered important. However, the interviewees told that this was most often not provided.

Conclusion:

These findings indicate that caring for a person with PD in the palliative care phase is a demanding experience for family caregivers. They experience psychological problems for many years before and after the death of the person with PD. Increasing healthcare professionals’ awareness of family and bereaved caregivers’ needs may mitigate these long-term detrimental effects.

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

INTRODUCTION

Palliative care in Parkinson's Disease (PD) is an effective intervention to improve quality of life, although historically, access and availability have been very restricted.

METHODS

We performed a retrospective cohort study using the National Inpatient Sample (NIS) data from 2007 to 2014. Diagnostic codes were used to identify patients with PD and palliative care referral. Trends were calculated and logistic analysis performed to identify predictors of palliative care use.

RESULTS

We identified 397,963 hospitalizations from 2007 to 2014 for patients with PD. Of these, 10,639 (2.67%) were referred to palliative care. The rate of consultation increased from 0.85% in 2007 to 4.49% in 2014. For 1 unit in year increase, there was 1.23 time the odds of receiving palliative consultation (OR 1.23, CI 1.21-1.25, p < 0.0001). Hispanics (OR 0.90, CI 0.81-1.01, p = 0.0550), Black (OR 0.90, CI 0.81-1.01, p = 0.0747) and White patients had similar rates of referral after adjustment. Women were less likely to be referred to palliative care (OR 0.90, CI 0.87-0.94, p < 0.0001). Other factors strongly associated with a higher rate of referrals included private insurance when compared to Medicare (OR 2.14, CI 1.89-2.41, p < 0.0001) and higher income (OR 1.41, CI 1.30-1.53, p < 0.0001).

CONCLUSION

There has been a significant increase in palliative care referrals among hospitalized patients with PD in the US, although the overall rate remains low. After controlling for confounders, racial and ethnic disparities were not found. Women, patients with Medicare/Medicaid, and those with lower income were less likely to be referred to palliative care.

RADPAC-PD: A tool to support healthcare professionals in timely identifying palliative care needs of people with Parkinson's disease

Background

Parkinson’s disease (PD) is a progressive degenerative disease without curative treatment perspectives. Even when palliative care for people with PD seems to be beneficial, the need for palliative care is often not timely recognized.

Aim

Our aim was to develop a tool that can help healthcare professionals in timely identifying palliative care needs in people with PD.

Design

We used a mixed-methods design, including individual and focus group interviews and a three-round modified Delphi study with healthcare professionals from a multidisciplinary field.

Results

Data from the interviews suggested two distinct moments in the progressive PD trajectory: 1) an ultimate moment to initiate Advance Care Planning (ACP); and 2) the actual start of the palliative phase. During the Delphi process, six indicators for ACP were identified, such as presence of frequent falls and first unplanned hospital admission. The start of the palliative phase involved four indicators: 1) personal goals have started to focus on maximization of comfort; 2) care needs have changed; 3) PD drug treatment has become less effective or an increasingly complex regime of drug treatments is needed; and 4) specific PD-symptoms or complications have appeared, such as significant weight loss, recurrent infections, or progressive dysphagia. Indicators for both moments are included in the RADboud indicators for PAlliative Care Needs in Parkinson’s Disease (RADPAC-PD) tool.

Conclusion

The RADPAC-PD may support healthcare professionals in timely initiating palliative care for persons with PD. Identification of one or more indicators can mark the need for ACP or the palliative phase. We expect that applying the RADPAC-PD, for example on an annual basis throughout the PD trajectory, can facilitate identification of the palliative phase in PD patients in daily practice. However, further prospective research is needed on the implementation of the RADPAC-PD.

Nursing care (palliative medicine) in patients with neuropsychiatric disorders

BACKGROUND AND PURPOSE

Palliative medicine is a special status focusing on the quality of life of patients suffering from special or advanced diseases. Palliative medicine can be helpful at any stage of the disease, including the diagnosis. Thus, the present study aims at reviewing the application of palliative care in mental disorders.

METHOD

In the present study, as many as 1,149 studies were found in the period of 1985 to 2018 by searching on different websites including Medline, Embase, ProQuest, Global Health, GoogleScholar, and Scopus. As many as 53 studies having to do with mental disorders were found, and more specifically, as many as 36 articles related to palliative medicine were applied.

FINDINGS

Reviewing the related literature indicates that the care needs of mental disorders patients are quite complicated. The findings indicated that predicting the complications of the disease, as well as advanced planning in terms of caring for these patients, are of significant importance. The findings indicated that over the last decade two palliative care models have been developed: integrative and consultative.

CONCLUSION

With the growth development of palliative care in developed countries, the knowledge of palliative care can be shared with the nurses and practitioners of neurological diseases, and this knowledge can be applied to palliate and reduce the pains and sufferings of the patients and their families.

[Parkinson's syndromes in geriatric patients : Epidemiological, clinical and therapeutic characteristics]

Due to their high prevalence, Parkinson's syndromes are exemplary geriatric syndromes. In addition to idiopathic Parkinson's disease, drug-induced and vascular Parkinson's syndromes are especially relevant in older age. A comprehensive anamnesis, thorough clinical neurological examination and rational additional diagnostics ensure the correct differential diagnostic classification. The multidimensional geriatric assessment is used to quantify the syndrome-specific ability impairments. The primary therapeutic objective in old age is the preservation of everyday competences. Drug treatment is centered around L‑dopa because of its favorable effect-side effect ratio. In cases of motor fluctuations, entacapone, opicapone or safinamide can be added, whereas dopamine agonists are generally unsuitable. Rivastigmine is indicated in mild to moderate Parkinson's dementia and furthermore can possibly improve gait stability. Speech therapy, as well as physical and occupational therapy, including the Parkinson's disease-specific Lee Silverman voice treatment are indispensable components of the multiprofessional treatment concept.

Deep Brain Stimulation at End of Life: Clinical and Ethical Considerations

Deep brain stimulation (DBS) is an implanted neurological device effective in treating motor symptoms of Parkinson disease (PD), such as tremor, rigidity, and bradykinesia. More than 150,000 patients worldwide have been implanted with DBS devices. Questions arise at the end of life concerning how to provide best care for patients with DBS, including its continued benefit or potential complications, yet, no published articles provide guidance for hospice providers regarding the management of DBS devices in end-of-life care. With contributions from hospice physicians, a neurosurgeon, and ethicists, this article provides recommendations to address clinical and ethical challenges in optimizing DBS for patients with PD nearing the end of life.

Palliative care for persons with Parkinson's disease: a qualitative study on the experiences of health care professionals

Background

Parkinson’s disease (PD) is a chronic and neurodegenerative disease associated with a wide variety of symptoms. The risk of complications increases with progression of the disease. These complications have a tremendous impact on the quality of life of people with PD. The aim of this study was to examine health care professionals’ experiences of potential barriers and facilitators in providing palliative care for people with PD in the Netherlands.

Methods

This was a qualitative descriptive study. The data were collected from 10 individual in-depth interviews and three focus groups (n = 29) with health care professionals. Health care professionals were selected based on a positive answer to the question: “In the past 2 years, did you treat or support a person with PD who subsequently died?” The data were analyzed by thematic text analysis.

Results

Health care professionals supported the development of a palliative care system for PD but needed to better understand the essence of palliative care. In daily practice, they struggled to identify persons’ needs due to interfering PD-specific symptoms such as cognitive decline and communication deficits. Timely addressing the personal preferences for providing palliative care was identified as an important facilitator. Health care professionals acknowledged being aware of their lack of knowledge and of their little competence in managing complex PD. Findings indicate a perceived lack of care continuity, fragmentation of services, time pressure and information discontinuity.

Conclusions

Health care professionals experienced several facilitators and barriers to the provision of palliative care to people with PD. There is a need to improve the knowledge on complex PD and the continuity of information, as well as optimize coordination and deliver care based on a persons’ preferences. Additional training can help to become more knowledgeable and confident.

Addressing sexuality and intimacy in people living with Parkinson's during palliative care and at the end of life

Sexuality and intimacy are poorly researched in both people living with Parkinson's and in older people. Triggers for discussion usually centre on sexual dysfunction and hypersexuality in relation to Parkinson's. However, there are many more factors that impact on physical and emotional connectedness. Despite highlighting this unmet need there are limited tools or comprehensive assessments available to help improve quality of life. Further research is required within this field, with emphasis on health professionals' education and on highlighting to patients that they have permission for this topic to be discussed and actioned.

Framing advance care planning in Parkinson disease: Patient and care partner perspectives

OBJECTIVE

Advance care planning (ACP) is a core quality measure in caring for individuals with Parkinson disease (PD) and there are no best practice standards for how to incorporate ACP into PD care. This study describes patient and care partner perspectives on ACP to inform a patient- and care partner-centered framework for clinical care.

METHODS

This is a qualitative descriptive study of 30 patients with PD and 30 care partners within a multisite, randomized clinical trial of neuropalliative care compared to standard care. Participants were individually interviewed about perspectives on ACP, including prior and current experiences, barriers to ACP, and suggestions for integration into care. Interviews were analyzed using theme analysis to identify key themes.

RESULTS

Four themes illustrate how patients and care partners perceive ACP as part of clinical care: (1) personal definitions of ACP vary in the context of PD; (2) patient, relationship, and health care system barriers exist to engaging in ACP; (3) care partners play an active role in ACP; (4) a palliative care approach positively influences ACP. Taken together, the themes support clinician initiation of ACP discussions and interdisciplinary approaches to help patients and care partners overcome barriers to ACP.

CONCLUSIONS

ACP in PD may be influenced by patient and care partner perceptions and misperceptions, symptoms of PD (e.g., apathy, cognitive dysfunction, disease severity), and models of clinical care. Optimal engagement of patients with PD and care partners in ACP should proactively address misperceptions of ACP and utilize clinic teams and workflow routines to incorporate ACP into regular care.

Randomized trial of care management to improve Parkinson disease care quality

OBJECTIVE

To test effects on care quality of Chronic Care Model-based Parkinson disease (PD) management.

METHODS

This 2-group stratified randomized trial involved 328 veterans with PD in southwestern United States. Guided care management, led by PD nurses, was compared to usual care. Primary outcomes were adherence to 18 PD care quality indicators. Secondary outcomes were patient-centered outcome measures. Data sources were telephone survey and electronic medical record (EMR). Outcomes were analyzed as intent-to-treat comparing initial and final survey and repeated-measures mixed-effects models.

RESULTS

Average age was 71 years; 97% of participants were male. Mean proportion of participants receiving recommended PD care indicators was significantly higher for the intervention than for usual care (0.77 vs 0.58) (mean difference 0.19, 95% confidence interval [CI] 0.16, 0.22). Of 8 secondary outcomes, the only significant difference of the changes over time was in the positive Patient Health Questionnaire-2 depression screen for intervention minus usual care (-11.52 [95% CI -20.42, -2.62]).

CONCLUSION

A nurse-led chronic care management intervention, Care Coordination for Health Promotion and Activities in Parkinson's Disease (CHAPS), substantially increased adherence to PD quality of care indicators among veterans with PD, as documented in the EMR. Of 8 secondary outcomes assessed, a screening measure for depressive symptomatology was the only measure that was better in the intervention compared to usual care. More telephone calls in CHAPS were the only utilization difference over usual care. While CHAPS appears promising for improving PD care, additional iterative research is needed to refine the CHAPS model in routine clinical care so that it measurably improves patient-centered outcomes (NCT01532986).

CLASSIFICATION OF EVIDENCE

This study provides Class I evidence that for patients with PD, CHAPS increased adherence to PD quality of care indicators.

Dementia and Parkinson's Disease: Similar and Divergent Challenges in Providing Palliative Care

Dementia and Parkinson's disease are incurable neurological conditions. Patients often experience specific, complex, and varying needs along their disease trajectory. Current management typically employs a multidisciplinary team approach. Recognition is growing that this team approach should also address palliative care issues to optimize quality of life for patient and family caregivers, but it remains unclear how palliative care is best delivered. To inspire future service development and research, we compare the trajectories and conceptualization of palliative care between dementia and Parkinson's disease. Both Parkinson's disease and dementia are characterized by a protracted course, with progressive but fairly insidious development of disability. However, patients with Parkinson's disease may experience relatively stable periods initially but with time, a wide range of debilitating symptoms develops, many of which do not respond well to treatment. Eventually, dementia develops in most Parkinson patients, while motor disability develops in many dementia patients. In both diseases, symptoms such as pain, apathy, sleeping problems, falls, and a high caregiver burden are prevalent. Advance care planning has benefits in terms of being prepared before the disease progresses into a stage with communication problems or severe cognitive impairment. However, for both conditions, the protracted disease trajectories complicate conceptualization of palliative care through different stages of the disease, with pertinent questions such as when to offer what interventions pro-actively. Given the similarities and differences, we should develop palliative approaches that are partially generic and partially disease-specific. These should be integrated seamlessly with disease-specific care. Substantial research is already being performed on dementia palliative care. This may also inform the further development of palliative care for Parkinson's disease, including an evaluation of palliative interventions and services.

Impaired Quality of Life and Need for Palliative Care in a German Cohort of Advanced Parkinson's Disease Patients

Background

Parkinson’s disease (PD) is the second most frequent neurodegenerative disease of the elderly. Patients suffer from various motor and non-motor symptoms leading to reduced health-related quality of life (HRQOL) and an increased mortality. Their loss of autonomy due to dementia, psychosis, depression, motor impairments, falls, and swallowing deficits defines a phase when palliative care interventions might help to sustain or even improve quality of life.

Objective

The aim of this study was to investigate the current status of palliative care implementation and quality of life in a local cohort of advanced PD patients in order to frame and improve future care.

Methods

76 geriatric patients with advanced idiopathic PD meeting the inclusion criteria for palliative care interventions were clinically evaluated by neurological examination using Movement Disorders Society Unified Parkinson’s Disease Rating Scale, Barthel Index, Montreal Cognitive Assessment Test, and a structured interview concerning palliative care implementation.

Results

HRQOL is severely reduced in our cohort of geriatric advanced PD patients. We found motor deficits, impairment of activities of daily living, depression, and cognitive decline as most relevant factors determining decreased HRQOL. Only 2.6% of our patients reported present implementation of palliative care. By contrast, 72% of the patients indicated an unmet need for palliative care.

Conclusion

Quality of life is dramatically affected in advanced PD patients. However, we found palliative care to be implemented extremely rare in their treatment concept. Therefore, geriatric patients suffering from advanced PD should be enrolled for palliative care to provide adequate and holistic treatment which may improve or sustain their quality of life.

Palliative care for patients with Parkinson's disease: study protocol for a mixed methods study

Background

Parkinson’s disease (PD) is a chronic, progressive neurological disorder with many intractable consequences for patients and their family caregivers. Little is known about the possibilities that palliative care could offer to patients and their proxies. Guidelines strongly recommend palliative care to improve the quality of life and – if needed – the quality of dying. However, providing palliative care to persons with PD involves specific challenges. For example, a timely initiation of palliative interventions is difficult because due to the gradually progressive nature of PD, there is often no clear marker for the transition from curative towards palliative care. Furthermore, there is little evidence to indicate which palliative care interventions are effective. Here, we describe the contours of a study that aims to examine the experiences of patients, (bereaved) family caregivers and professionals, with the aim of improving our knowledge about palliative care needs in PD.

Methods/design

We will perform a mixed methods study to evaluate the experiences of patients, (bereaved) family caregivers and palliative care professionals. In this study, we focus on Quality of Life, Quality of Care, perceived symptoms, caregiver burden and collaboration between professionals. In phase 1, we will retrospectively explore the views of bereaved family caregivers and professionals by conducting individual interviews and focus group interviews. In phase 2, 5–15 patients with PD and their family caregiver will be followed prospectively for 8–12 months. Data collection will involve semi-structured interviews and questionnaires at three consecutive contact moments. Qualitative data will be audio recorded, transcribed and analyzed using CAQDAS. If patients pass away during the study period, a bereavement interview will be done with the closest family caregiver.

Discussion

This study will offer a broad perspective on palliative care, and the results can be used to inform a palliative care protocol for patients with PD. By describing the experiences of patients, (bereaved) family caregivers and professionals with palliative care, this investigation will also establish an important ground for future intervention research.

Palliative Care in Neurology

Palliative medicine is a specialty that focuses on improving the quality of life for patients with serious or advanced medical conditions, and it is appropriate at any stage of disease, including at the time of diagnosis. Neurologic conditions tend to have high symptom burdens, variable disease courses, and poor prognoses that affect not only patients but also their families and caregivers. Patients with a variety of neurologic conditions such as Parkinson disease, dementia, amyotrophic lateral sclerosis, brain tumors, stroke, and acute neurologic illnesses have substantial unmet needs that can be addressed through a combination of primary and specialty palliative care. The complex needs of these patients are ideally managed with a comprehensive approach to care that addresses the physical, psychological, social, and spiritual aspects of care in an effort to reduce suffering. Early discussions about prognosis, goals of care, and advance care planning are critical as they can provide guidance for treatment decisions and allow patients to retain a sense of autonomy despite progressive cognitive or functional decline. With the rapid growth in palliative care across the United States, there are opportunities to improve the palliative care knowledge of neurology trainees, the delivery of palliative care to patients with neurologic disease by both neurologists and nonneurologists, and the research agenda for neuropalliative care.

Palliative care for Parkinson's disease: Patient and carer's perspectives explored through qualitative interview

BACKGROUND

Palliative care is recommended for non-malignant illnesses, including Parkinson's disease. However, past research with healthcare workers highlights unmet palliative needs in this population and referral rates to Specialist Palliative Care are low. Some healthcare workers perceive a 'fear' in their patients about introducing palliative care. However, less is known about the views of people with Parkinson's disease and their carers about palliative care.

AIM

(1) To explore the palliative care and related issues most affecting people with Parkinson's disease and their families and (2) to examine perceptions about/understanding of palliative care.

DESIGN

This was a qualitative study; semi-structured interviews were conducted, transcribed and analysed using thematic analysis.

SETTING/PARTICIPANTS

A total of 31 people participated, both people with Parkinson's disease ( n = 19) and carers ( n = 12), across three Movement Disorder Clinics in the Republic of Ireland.

RESULTS

People with Parkinson's disease and their carers were unfamiliar with the term palliative care. When informed of the role of palliative care, most felt that they would benefit from this input. People with Parkinson's disease and carers experienced a high illness burden and wanted extra support. Crises requiring Specialist Palliative Care involvement may occur at diagnosis and later, with advancing illness. Participants wanted more information about palliative care and especially further supports to address their psychosocial needs.

CONCLUSION

A holistic palliative care approach could address the complex physical and psychosocial symptoms experienced by people with Parkinson's disease and their carers, and people with Parkinson's disease and their carers are open to palliative care. Further research needs to explore how palliative care can be introduced into the routine care for people with Parkinson's disease.

Palliative Care and Parkinson's Disease: Caregiver Perspectives

BACKGROUND

Palliative care for Parkinson's disease (PD) is an emerging area of interest for clinicians, patients and families. Identifying the palliative care needs of caregivers is central to developing and implementing palliative services for families affected by PD. The objective of this paper was to elicit PD caregiver needs, salient concerns, and preferences for care using a palliative care framework.

MATERIALS AND METHODS

11 PD caregivers and one non-overlapping focus group (n = 4) recruited from an academic medical center and community support groups participated in qualitative semi-structured interviews. Interviews and focus group discussion were digitally recorded, transcribed and entered into ATLAS.ti for coding and analysis. We used inductive qualitative data analysis techniques to interpret responses.

RESULTS

Caregivers desired access to emotional support and education regarding the course of PD, how to handle emergent situations (e.g. falls and psychosis) and medications. Participants discussed the immediate impact of motor and non-motor symptoms as well as concerns about the future, including: finances, living situation, and caretaking challenges in advanced disease. Caregivers commented on the impact of PD on their social life and communication issues between themselves and patient. All participants expressed interest and openness to multidisciplinary approaches for addressing these needs.

CONCLUSIONS

Caregivers of PD patients have considerable needs that may be met through a palliative care approach. Caregivers were receptive to the idea of multidisciplinary care in order to meet these needs. Future research efforts are needed to develop and test the clinical and cost effectiveness of palliative services for PD caregivers.

Palliative Care for Patients and Families With Parkinson's Disease

Parkinson's disease is the second most common neurodegenerative disease worldwide. There is widespread consensus that Parkinson patients, their carers, and clinicians involved in their care would benefit from a fully integrated, need-based provision of palliative care. However, the concept of palliative care in Parkinson's disease is still poorly defined and, consequently, poorly implemented into daily clinical practice. A particular challenge is the gradually progressive nature of Parkinson's disease-with insidiously increasing disability-making it challenging to clearly define the onset of palliative care needs for Parkinson patients. As people with Parkinson's disease are now living longer than in the past, future research needs to develop a more robust evidence-based approach to clarify the disease events associated with increased palliative care needs, and to examine these, prospectively, in an integrated palliative care service. The modern palliative care outlook, termed "simultaneous care,",is no longer restricted to the final stage of disease. It involves incorporating a continuity of care, effective management of the chronic-palliative interface, and a multidisciplinary network of professionals working both in the community and in specialized clinics, with active involvement of caregivers. Although promising, there is still a need to demonstrate the effectiveness of palliative care for patients with Parkinson's disease.

Unmet needs in Parkinson's disease: New horizons in a changing landscape

The success of levodopa and other classes of drugs have meant that most people with Parkinson's disease enjoy a good quality of life for many years. However, despite the availability of several drugs and formulations that can be used as monotherapy and in combination, there are a number of disease features that the current therapies are unable to address. The disease continues to progress despite treatment, patients suffer from a myriad of motor and non-motor symptoms, and a neuroprotective therapy is urgently required. To move forward with medical and surgical management, it is important to consider new insights that recent research offers and in this review we examine how a better understanding of the disease pathology and progression might improve and enrich our daily clinical practice. It is also timely to consider the service provision changes that will increasingly be needed to effectively manage the needs of the aging population.

Strategies to maintain quality of life among people with Parkinson's disease: what works?

Among chronic neurodegenerative disorders, Parkinson's disease (PD) is one of the most difficult and challenging to tackle as several motor and nonmotor features influence the patients' quality of life (QoL) and daily activities. Assessing patients QoL with valid instruments and gathering knowledge about the determinants that affect QoL in individuals with PD are the basis of an efficient caring strategy. In addition to the known motor symptoms, nonmotor disorders must also be comprehensively tracked and targeted for treatment to enhance QoL. A holistic strategy to maintain QoL in people with PD should consist of a multidisciplinary, personalized and patient-centered approach with timely administration of palliative care and efficient involvement of caregivers and family members.
