Improving Documentation of Impulse Control Disorders at a Movement Disorder Program During the COVID-19 Pandemic

Background and Objectives

Impulse control disorders (ICD) are a group of behaviors in Parkinson disease (PD), (compulsive buying, gambling, binge eating, craving sweets, and hypersexuality) that occur in up to 20% of individuals with PD, sometimes with devastating results. We sought to determine the rate of ICD screening based on 2020 quality measures for PD care by the American Academy of Neurology.

Methods

We conducted a quality improvement project to document and improve physician ICD screening in a tertiary movement disorder program. Serial medical records were reviewed for 5 weeks before and 13 weeks after an educational session and documentation tool deployments in 2020. Inclusion criteria included the following: idiopathic PD, PD dementia (PDD), or dementia with Lewy bodies (DLB). Individual encounters for 109 patients preintervention and 276 patients postintervention were reviewed.

Results

There was no difference between the preintervention and postintervention (pre-IG vs post-IG, respectively) in terms of age, male to female ratio, proportion of patients with PD, PDD, or DLB, duration of diagnosis, or levodopa equivalents. There was a shift to increased ICD queries above the median for the study period (28.8%) for 7 consecutive weeks in post-IG. The frequency of ICD diagnosis was not different from pre-IG to post-IG (95% confidence interval, 0-32.6 vs 2.7-13.4%, p = 0.444).

Discussion

ICD queries immediately after ICD education and dissemination of documentation tools increased. Both preintervention and postintervention groups were similar in demographic and clinical characteristics. This program was instituted at the height of wave 2 of the COVID-19 pandemic in Alberta during staff redeployment and 100% shift to telemedicine ambulatory care. Our results demonstrate that amid a crisis, quality improvement can still be effective with education and provision of tools for clinicians.

Palliative care in Parkinson disease and related disorders

Although neuropalliative care is a relatively new field, there is increasing evidence for its use among the degenerative parkinsonian syndromes, including idiopathic Parkinson disease, progressive supranuclear palsy, multiple system atrophy, dementia with Lewy bodies, and corticobasal syndrome. This chapter outlines the current state of evidence for palliative care among individuals with the degenerative parkinsonian syndromes with discussion surrounding: (1) disease burden and needs across the conditions; (2) utility, timing, and methods for advance care planning; (3) novel care models for the provision of palliative care; and 4) end-of-life care issues. We also discuss currently unmet needs and unanswered questions in the field, proposing priorities for research and the assessment of implemented care models.

Cannabinoids in movement disorders

INTRODUCTION

On the basis of both scientific progress and popular lore, there is growing optimism in the therapeutic potential of cannabis (marijuana) and cannabinoid-based chemicals for movement disorders. There is also notable skepticism regarding the scientific basis for this therapeutic optimism and significant concerns regarding the safety and regulation of cannabinoid products, particularly those available without prescription.

METHODS

In recognition of the high interest and controversial nature of this subject, the meeting committee of the International Parkinson and Movement Disorders Society arranged for a talk on cannabis at the 2019 annual meeting's Controversies in Movement Disorders plenary session. This paper summarizes the highlights of this session.

RESULTS

The endocannabinoid system is strongly tied to motor function and dysfunction, with basic research suggesting several promising therapeutic targets related to cannabinoids for movement disorders. Clinical research on cannabinoids for motor and nonmotor symptoms in Parkinson's disease, Huntington's disease, Tourette's syndrome, dystonia, and other movement disorders to date are promising at best and inconclusive or negative at worst. Research in other populations suggest efficacy for common symptoms like pain. While social campaigns against recreational cannabinoid use focus on cognitive changes in adolescents, the long-term sequelae of regulated medical use in older adults with movement disorders is unknown. The overall risks of cannabinoids may be similar to other commonly used medications and include falls and apathy.

CONCLUSION

Further research is greatly needed to better understand the actual clinical benefits and long-term side effects of medical cannabis products for movement disorders indications and populations.

What's in the Sauce? The Specific Benefits of Palliative Care for Parkinson's Disease

CONTEXT

Increasing evidence demonstrates the benefits of palliative care among individuals with Parkinson's disease and related disorders (PDRD), but the critical components that contribute to therapeutic effects are not well understood.

OBJECTIVES

To determine the specific items most responsive to a palliative care intervention in PDRD and identify key correlates of improvement in patient and care partner outcomes.

METHODS

The main trial was a pragmatic comparative effectiveness trial of outpatient integrated palliative care compared to standard care among participants with PDRD (NCT02533921), showing significantly higher patient QOL at six months and lower care partner burden at 12 months. We used longitudinal regression models to analyze changes in subdomains of patient QOL and care partner burden and Spearman correlations to evaluate key correlates of change scores in patient and care partner outcomes. We performed a secondary analysis of data from 210 patients and 175 care partners.

RESULTS

Compared to controls, patients in the intervention reported greater improvement in perceptions of the "self as a whole" at six months (coeff = 0.22, P < 0.05) and care partners reported greater reduction in stress, anger, and loss of control at 12 months (coeff = -.40, -0.25, -0.31, P < 0.05). Positive change in numerous patient non-motor symptoms and grief correlated with improved patient QOL, reduced patient anxiety, and increased care partner spirituality. Alleviation of care partner anxiety and depression correlated with reduced care partner burden.

CONCLUSION

Specific benefits of an integrated palliative approach in PDRD include improvement in patient holistic self-impressions, care partner self-efficacy, and non-motor symptoms.

Key concepts and opportunities

Neuropalliative care is an emerging field dedicated to applying palliative care approaches to meet the needs of persons living with neurologic illness and their families. The development of this field acknowledges the unique needs of this population, including in terms of neuropsychiatric symptoms, the impact of neurologic illness on personhood, and the logistics of managing neurologic disability. In defining the goals of this field, it is important to distinguish between neuropalliative care as an approach to care, as a skillset, as a medical subspecialty, and as a public health goal as each of these constructs offers their own contributions and opportunities. As a newly emerging field, there are nearly unlimited opportunities to improve care through research, clinical care, education, and advocacy.

Dopaminergic Therapy for Motor Symptoms in Early Parkinson Disease Practice Guideline Summary: A Report of the AAN Guideline Subcommittee

BACKGROUND AND OBJECTIVES

To review the current evidence on the options available for initiating dopaminergic treatment of motor symptoms in early-stage Parkinson disease and provide recommendations to clinicians.

METHODS

A multidisciplinary panel developed practice recommendations, integrating findings from a systematic review and following an Institute of Medicine-compliant process to ensure transparency and patient engagement. Recommendations were supported by structured rationales, integrating evidence from the systematic review, related evidence, principles of care, and inferences from evidence.

RESULTS

Initial treatment with levodopa provides superior motor benefit compared to treatment with dopamine agonists, whereas levodopa is more likely than dopamine agonists to cause dyskinesia. The comparison of different formulations of dopamine agonists yielded little evidence that any one formulation or method of administration is superior. Long-acting forms of levodopa and levodopa with entacapone do not appear to differ in efficacy from immediate-release levodopa for motor symptoms in early disease. There is a higher risk of impulse control disorders associated with the use of dopamine agonists than levodopa. Recommendations on initial therapy for motor symptoms are provided to assist the clinician and patient in choosing between treatment options and to guide counseling, prescribing, and monitoring of efficacy and safety.

Clinical perception and management of Parkinson's disease during the COVID-19 pandemic: A Canadian experience

Background

The COVID-19 pandemic has necessitated the social isolation of the population and the rapid implementation of remote care for patients with neurodegenerative diseases. The objective of this study was to explore the perceived impact of confinement in patients with Parkinson's disease and document the effects of gender and living environment.

Methods

We recruited two cohorts from the Canadian provinces of Québec and Alberta, which differed in the dynamics of COVID-19 spreading at the time of the study, and administered a questionnaire on the perceived effects of confinement on daily living and disease management.

Results

The data reveals that approximately half of the patients experienced a change in one or more clinical symptoms, with differences observed between gender (e.g. day-to-day changes in slowness in men, aggravated headaches in women) and geographic location (e.g. increased depression in Alberta but reduced sleep quality in Québec). Furthermore, participants identifying as women or living in Alberta implemented more frequently home or online exercise. Lastly, high levels of satisfaction with phone or video consultations did not translate into a sustained interest to pursue this mode of healthcare.

Conclusions

This study suggests that COVID-19-related confinement affected Parkinson's disease manifestation and management. Patients also reported varying levels of interest to continue remote care. A number of differences reported in our study were seemingly related to gender and living environment.

DBS-Edmonton App, a Tool to Manage Patient Expectations of DBS in Parkinson Disease

Objective

After deep brain stimulation (DBS) for Parkinson disease (PD), patients often do not report the level of satisfaction anticipated. This misalignment can relate to patients' expectations for an invasive treatment and insufficient knowledge of DBS's effectiveness in relieving motor and nonmotor symptoms (NMS). Patient satisfaction depends on expectations and goals for treatment. We hypothesized that improving patient education with a patient-centered shared decision-making tool emphasizing autonomy would improve patient satisfaction and clinical outcome.

Methods

We developed a computer application (DBS-Edmonton app), allowing patients with PD to input their symptoms and to learn how effective DBS addresses their prioritized symptoms. Sixty-two volunteers referred for DBS used the DBS-Edmonton app. DBS-related knowledge and patient perceptions of the DBS-Edmonton app were assessed with pre- and post-use questionnaires. Fourteen of 24 patients who proceeded to DBS achieved optimization at 6 months. Perceived functional improvement was assessed and compared with 12 control patients with DBS who did not use the DBS-Edmonton app.

Results

All 62 volunteers considered the DBS-Edmonton app helpful and would recommend it to others. There was improved knowledge about how NMS and axial symptoms respond to DBS. Postoperatively, there was no significant difference in symptoms improvement assessed by standard scales between the groups. Volunteers who used the DBS-Edmonton app had greater satisfaction (p = 0.014).

Conclusion

This interventional study showed that the DBS-Edmonton app improved DBS-related knowledge and patient satisfaction, independent of the objective motor outcome. It may assist patients in deciding to proceed to DBS and can be easily incorporated into practice to improve patient satisfaction post-DBS.

Access and Attitudes Toward Palliative Care Among Movement Disorders Clinicians

BACKGROUND

Neuropalliative care is an emerging field for those with neurodegenerative illnesses, but access to neuropalliative care remains limited.

OBJECTIVE

We sought to determine Movement Disorder Society (MDS) members' attitudes and access to palliative care.

METHODS

A quantitative and qualitative survey instrument was developed by the MDS Palliative Care Task Force and e-mailed to all members for completion. Descriptive statistics and qualitative analysis were triangulated.

RESULTS

Of 6442 members contacted, 652 completed the survey. Completed surveys indicating country of the respondent overwhelmingly represented middle- and high-income countries. Government-funded homecare was available to 54% of respondents based on patient need, 25% limited access, and 21% during hospitalization or an acute defined event. Eighty-nine percent worked in multidisciplinary teams. The majority endorsed trigger-based referrals to palliative care (75.5%), while 24.5% indicated any time after diagnosis was appropriate. Although 66% referred patients to palliative care, 34% did not refer patients. Barriers were identified by 68% of respondents, the most significant being available workforce, financial support for palliative care, and perceived knowledge of palliative care physicians specific to movement disorders. Of 499 respondents indicating their training in palliative care or desire to learn these skills, 55% indicated a desire to gain more skills.

CONCLUSIONS

The majority of MDS member respondents endorsed a role for palliative care in movement disorders. Many members have palliative training or collaborate with palliative care physicians. Although significant barriers exist to access palliative care, the desire to gain more skills and education on palliative care is an opportunity for professional development within the MDS. © 2021 International Parkinson and Movement Disorder Society.

White matter hyperintensities in patients with Parkinson's disease: A systematic review and meta-analysis

INTRODUCTION

Mechanisms driving neurodegeneration in Parkinson's disease (PD) are unclear and neurovascular dysfunction may be a contributing factor. White matter hyperintensities (WMH) are commonly found on brain MRI in patients with PD. It is controversial if they are more prevalent or more severe in PD compared with controls. This systematic review aims to answer this question.

METHODS

A systematic search of electronic databases was conducted for studies of WMH in patients with PD. A qualitative synthesis was done for studies reporting WMH prevalence or WMH scores on a visual rating scale (VRS). In studies reporting total WMH volume, the difference between patients with PD and controls was pooled using random effects meta-analysis.

RESULTS

Among 3860 subjects from 24 studies, 2360 were cases and 1500 controls. Fifteen studies reported WMH scores and four studies reported the prevalence of WMH. On VRS, five studies reported no difference in WMH scores, three found higher WMH scores in PD compared to controls, three reported increased WMH scores either in periventricular or deep white matter, and four reported higher scores only in PD with dementia. In studies reporting WMH volume, there was no difference between patients with PD and controls (pooled standardized mean difference = 0.1, 95%CI: -0.1-0.4, I² = 81%).

CONCLUSION

WMH are not more prevalent or severe in patients with PD than in age-matched controls. PD dementia may have more severe WMH compared to controls and PD with normal cognition. Prospective studies using standardized methods of WMH assessment are needed.

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.

Device-aided therapies for advanced Parkinson disease: insights from an international survey

PURPOSE

In the advanced stage of Parkinson disease (PD), therapeutic interventions include device-aided therapies such as continuous subcutaneous apomorphine infusion (CSAI), levodopa-carbidopa intestinal gel (LCIG) infusion, and deep brain stimulation (DBS). Recent evidence has underlined the general lack of randomized, blinded, head-to-head studies on device-aided therapies for advanced PD.

METHODS

To better clarify the real-world attitude of clinicians on this matter, we conducted an international survey of forty-four experienced movement disorder specialists regarding the management of device-aided therapies in advanced PD.

RESULTS

Our international survey showed a general agreement that nowadays, motor complications are less common compared to the past (59% agreement), that guidelines to identify candidates for device-aided therapies are currently lacking (57% agreement), and that device-aided therapies will have increased demand in the future (75% agreement).

CONCLUSIONS

We conclude that guidelines to assist clinicians and patients to choose device-aided therapies are required.

Parkinson's disease advanced therapies - A systematic review: More unanswered questions than guidance

In advanced Parkinson's disease (PD), therapeutic interventions include device-aided therapies such as continuous subcutaneous apomorphine infusion (CSAI), levodopa-carbidopa intestinal gel (LCIG) infusion, and deep brain stimulation (DBS). We reappraised the evidence guiding the decision of appropriate device-aided therapies in advanced PD, and systematically reviewed the literature (including ongoing clinical trials) comparing CSAI, LCIG, DBS in terms of efficacy and cost-effectiveness, with particular consideration to possible conflicts of interests. Of 14,980 documents screened, sixteen were included (4 and 13 studies examining efficacy and cost-effectiveness, respectively). LCIG and DBS showed higher efficacy compared to best medical therapy (BMT). DBS was more expensive than BMT and LCIG. Lifetime costs of CSAI were lower of those of DBS, and DBS lifetime costs were lower than those of LCIG. The majority of studies (11 out of 16) showed direct or indirect sponsorship from pharmaceutical or device companies. Only one ongoing clinical trial comparing LCIG with DBS was found. Device-aided therapies address unmet needs in advanced PD. LCIG and DBS are superior to BMT in head-to-head studies; however, initial and lifetime costs should be considered when choosing those therapies. Guidelines to assist clinicians and patients to choose device-aided therapies, free from conflict of interests, are required.

Leadership, recognition awards, and publication by men and women in the American Academy of Neurology

Objective

To study sex differences with respect to publications, leadership, and recognition awards in the American Academy of Neurology (AAN) in light of recent research highlighting inequities in these domains.

Methods

We examined medical school graduation, neurology residency (using American Medical Association and American Council for Graduate Medical Education data), membership in the AAN, first and last authorship in Neurology®, membership on AAN committees, and AAN recognition awards by sex for 1997, 2007, and 2017.

Results

Female medical students were less likely to enter neurology residency in 1997 only. In 2007 and 2017, there was no proportionate difference between men and women as last author, a surrogate for senior member of the author panel. In 2017, women were proportionately more likely to be first authors than men, a surrogate for principal investigator of the study. Committee membership was less for women in 1997 and 2007 (p < 0.001) but was not proportionately different in 2017 (p = 0.534). Women were proportionately more likely to receive recognition awards in all years studied (1997 p = 0.008, 2007 p < 0.001, 2017 p < 0.001), although absolute numbers of women were lower.

Conclusions

Female membership, leadership (through committee membership), and publications as last author were lower in 1997 in the AAN. These same metrics demonstrated substantial proportionate changes, with no differences in last authorship in 2007 and 2017, greater likelihood for women to be first author in 2017, no differences in committee membership in 2017, and greater likelihood of receiving awards determined by merit in all 3 years.

Optimizing future planning in Parkinson disease: suggestions for a comprehensive roadmap from patients and care partners

BACKGROUND

Living with Parkinson disease (PD) is complicated by an unpredictable disease course which can delay planning for future needs. This study explores patient and care partner needs related to future planning using a palliative care framework with physical, psychological, social, cultural, end-of-life, and ethical aspects of care in PD to guide analysis.

METHODS

Secondary analysis of patient and care partner interviews from a randomized clinical trial comparing interdisciplinary outpatient palliative care versus standard care for individuals with PD and care partners in an academic setting. Sixty participants were interviewed (30 patients and 30 care partners) about needs related to future planning. Team-based thematic analysis was used to identify key themes.

RESULTS

Many care partners and patients living with PD described a desire for information about what to expect and how to plan for the future. Participants posed multiple questions about PD progression and devised the metaphor of a "roadmap" as a guide for decision making and planning. When exploring the concept of a PD roadmap, five themes emerged: (I) desire for a comprehensive tool for future planning, such as a roadmap, (II) care partner preferences for specific future planning, (III) PD-related life changes as opportunity for future planning and decision-making, (IV) cues from family, peers, and medical professionals about "location" on the roadmap, and (V) opportunities and challenges to integrating a PD roadmap into patient-centered care.

CONCLUSIONS

Patients and care partners described key needs related to future planning that can inform a comprehensive roadmap to assist with education, communication, and decision making. A roadmap tool can promote individualized anticipatory guidance and multidimensional shared decision-making discussions between patients, care partners, and the healthcare team related to PD progression.

Movement disorders in pregnancy

Movement disorders in women during pregnancy are uncommon. Therefore, high quality studies are limited, and guidelines are lacking for the treatment of movement disorders in pregnancy, thus posing a significant therapeutic challenge for the treating physicians. In this chapter, we discuss movement disorders that arise during pregnancy and the preexisting movement disorders during pregnancy. Common conditions encountered in pregnancy include but are not limited to restless legs syndrome, chorea gravidarum, Parkinson disease, essential tremor, and Huntington disease as well as more rare movement disorders (Wilson's disease, dystonia, etc.). This chapter summarizes the published literature on movement disorders and pharmacologic and surgical considerations for neurologists and physicians in other specialties caring for patients who are pregnant or considering pregnancy.

Patient and caregiver characteristics associated with caregiver burden in Parkinson's disease: a palliative care approach

BACKGROUND

Parkinson's disease (PD) is a neurodegenerative disorder associated with caregiver burden. Higher rates of burden are associated with adverse outcomes for caregivers and patients. Our aim was to understand patient and caregiver predictors of caregiver burden in PD from a palliative care approach.

METHODS

We conducted a cross-sectional analysis of baseline data from PD patients and caregivers in a randomized trial of outpatient palliative care at three study sites: University of Colorado, University of Alberta, and University of California San Francisco. The primary outcome measure of caregiver burden, the Zarit Burden Interview (ZBI), was compared against the following patient and caregiver variables: site of care, age, disease/caretaking duration, presence of atypical parkinsonism, race, income, education level, deep brain stimulation status, the Unified Parkinson's Disease Rating Scale (UPDRS) and Edmonton Symptom Assessment System Revised: Parkinson Disease (ESAS) for symptom severity and burden, the Montreal Cognitive Assessment (MoCA) for cognitive function, Quality of Life in Alzheimer's Disease (QOL-AD) scale for patient and caregiver perspectives on patient general quality of life, Parkinson's Disease Questionnaire 39 (PDQ-39) scale for health-related quality of life, Hospital Anxiety and Depression Scale (HADS) for patient and caregiver mood, Prolonged Grief Questionnaire, Functional Assessment of Chronic Illness Therapy- Spiritual Well-Being (FACIT-SP) of patient and caregiver, and Palliative Performance Scale for functional status. A stepwise multivariate linear regression model was used to determine associations with ZBI.

RESULTS

A total of 175 patients (70.9% male; average age 70.7±8.1 years; average disease duration 117.2±82.6 months), and 175 caregivers (73.1% female; average age 66.1±11.1 years) were included. Patient spiritual well-being (FACIT-SP Faith subscale, r2=0.024, P=0.0380), patient health-related quality of life (PDQ-39, r2=0.161, P<0.0001), caregiver depression (HADS Depression, r2=0.062, P=0.0014), caregiver anxiety (HADS Anxiety, r2=0.077, P=0.0002), and caregiver perspective on patient quality of life (QOL-AD Caregiver Perspective, r2=0.088, P<0.0001) were significant contributors to ZBI scores.

CONCLUSIONS

Patient and caregiver factors contribute to caregiver burden in persons living with PD. These results suggest targets for future interventions to improve caregiver support.

Measuring quality of life in palliative care for Parkinson's disease: A clinimetric comparison

INTRODUCTION

Quality of life (QOL) assessments allow for more complete evaluation of patients' lived experiences in relation to chronic conditions, such as Parkinson's disease (PD). In palliative care, such instruments are vital to ensure QOL issues are catalogued and addressed for patients. However, little is known regarding the psychometric properties of quality of life scales for use in palliative care for PD, specifically.

METHODS

210 participants with parkinsonian disorders, who participated in a larger palliative intervention clinical trial, completed four quality of life scales (PDQ-39, PROMIS-29, QOL-AD, and McGill QOL) at baseline and post-intervention. Psychometric properties, including internal consistency and concurrent validity, were examined. Factor analyses were performed to evaluate relationships between scale items. Minimal clinically important differences (MCID) and responsiveness were calculated for each scale.

RESULTS

All scales demonstrated good internal consistency and concurrent validity. Factor analyses revealed few deviations from the defined subdomains of the scales. Mean absolute MCID values were estimated at 12.7, 10.9, 3.9, and 18.9 for PDQ-39, PROMIS-29, QOL-AD, and McGill QOL, respectively. The PDQ-39 and PROMIS-29 demonstrated higher responsiveness to palliative intervention, while the QOL-AD was more responsive in the control group.

CONCLUSIONS

The PDQ-39, PROMIS-29, QOL-AD, and McGill QOL are all valid for use in PD palliative care, though subdomains of the scales in this population may differ slightly from those initially defined. We recommend the use of PDQ-39 and PROMIS-29 as outcome measures in clinical trials for palliative care in PD, though the QOL-AD may be superior for tracking disease progression.

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.

Age and sex differences in burnout, career satisfaction, and well-being in US neurologists

OBJECTIVE

To examine age and sex differences in burnout, career satisfaction, and well-being in US neurologists.

METHODS

Quantitative and qualitative analyses of men's (n = 1,091) and women's (n = 580) responses to a 2016 survey of US neurologists.

RESULTS

Emotional exhaustion in neurologists initially increased with age, then started to decrease as neurologists got older. Depersonalization decreased as neurologists got older. Fatigue and overall quality of life in neurologists initially worsened with age, then started to improve as neurologists got older. More women (64.6%) than men (57.8%) met burnout criteria on univariate analysis. Women respondents were younger and more likely to work in academic and employed positions. Sex was not an independent predictive factor of burnout, fatigue, or overall quality of life after controlling for age. In both men and women, greater autonomy, meaning in work, reasonable amount of clerical tasks, and having effective support staff were associated with lower burnout risk. More hours worked, more nights on call, higher outpatient volume, and higher percent of time in clinical practice were associated with higher burnout risk. For women, greater number of weekends doing hospital rounds was associated with higher burnout risk. Women neurologists made proportionately more negative comments than men regarding workload, work-life balance, leadership and deterioration of professionalism, and demands of productivity eroding the academic mission.

CONCLUSIONS

We identified differences in burnout, career satisfaction, and well-being in neurologists by age and sex. This may aid in developing strategies to prevent and mitigate burnout and promote professional fulfillment for different demographic subgroups of neurologists.

Top Ten Tips Palliative Care Clinicians Should Know About Parkinson's Disease and Related Disorders

Parkinson's disease (PD) affects 1%-2% of individuals older than 60 years and is the 14th leading cause of death in the United States. People with PD, across all stages of the disease, suffer from a significant symptom burden that includes many nonmotor symptoms (such as depression, fatigue, pain, and dementia), and most will ultimately die from complications of this degenerative and incurable illness. Even at diagnosis, a palliative care (PC) approach can help the patient adjust to his or her diagnosis and maintain an optimal quality of life. We brought together a team of PD and PC experts to assemble practical tips for the care of people with PD. The "Top 10" format emphasizes the most relevant issues to enable PC clinicians to provide optimal care for those suffering with this complex neurodegenerative disease.

A Mixed-Methods Approach to Understanding the Palliative Needs of Parkinson’s Patients

Parkinson’s disease (PD) is the second-most common age-related neurodegenerative disorder. Despite recommendations for a palliative approach, little is known about what palliative needs are unmet by standard care. This study aims to (a) identify palliative needs of PD patients, (b) determine the relationship between palliative needs and health-related quality of life (HRQoL), and (c) probe into factors affecting HRQoL. PD patients and neurologists were recruited for a survey on palliative need; a subset of patients was interviewed. Significant differences between physicians and patients were found in Physical, Psychological, Social, Financial, and Spiritual domains. Physical and Psychological needs predicted HRQoL. Primary themes across interviews included (a) lack of healthcare education and (b) need for care coordination. Secondary themes included (a) the importance of support groups, (b) the role of spirituality/religion, and (c) the narrow perceived role of the neurologist. Findings highlight the importance of coordinated individualized care.

Treatment of Advanced Parkinson Disease and Related Disorders

PURPOSE OF REVIEW

Parkinson disease often spans decades of a patient's lifetime. Over time, nonmotor symptoms predominate and may limit dopaminergic therapy. Neurologists continue to play a vital role in treatment. In addition to balancing neurobehavioral complications of Parkinson disease with motor benefit, addressing nonmotor symptoms common in the advanced stage may improve quality of life and reduce symptom burden. Symptoms such as dysphagia, constipation, urinary dysfunction, orthostatic hypotension, and pain respond to nonpharmacologic and pharmacologic therapies.

RECENT FINDINGS

Evidence for treatment of many nonmotor symptoms is weak or lacking. The evidence for treatment of the atypical parkinsonian syndromes (progressive supranuclear palsy, multiple system atrophy, and corticobasal degeneration) in advanced stages is even more scant.

SUMMARY

Engaging palliative care physicians in the joint care of patients can provide patients with access to expertise in end-of-life issues. Neurologic illnesses have specific hospice criteria to guide clinicians for referrals. Evidence supports that assisting patients with advance directives can result in improved satisfaction with care and improved quality of life in the last weeks of life. Neurologists can remain engaged in their patients' care throughout the course of illness.

Using social exchange theory to understand non-terminal palliative care referral practices for Parkinson's disease patients

BACKGROUND

A palliative approach is recommended in the care of Parkinson's disease patients; however, many patients only receive this care in the form of hospice at the end of life. Physician attitudes about palliative care have been shown to influence referrals for patients with chronic disease, and negative physician perceptions may affect early palliative referrals for Parkinson's disease patients.

AIM

To use Social Exchange Theory to examine the association between neurologist-perceived costs and benefits of palliative care referral for Parkinson's disease patients and their reported referral practices.

DESIGN

A cross-sectional survey study of neurologists.

SETTING/PARTICIPANTS

A total of 62 neurologists recruited from the National Parkinson Foundation, the Medical Association of Georgia, and the American Academy of Neurology's clinician database.

RESULTS

Participants reported significantly stronger endorsement of the rewards ( M = 3.34, SD = 0.37) of palliative care referrals than the costs ( M = 2.13, SD = 0.30; t(61) = -16.10, p < 0.0001). A Poisson regression found that perceived costs, perceived rewards, physician type, and the number of complementary clinicians in practice were significant predictors of palliative care referral.

CONCLUSION

Physicians may be more likely to refer patients to non-terminal palliative care if (1) they work in interdisciplinary settings and/or (2) previous personal or patient experience with palliative care was positive. They may be less likely to refer if (1) they fear a loss of autonomy in patient care, (2) they are unaware of available programs, and/or (3) they believe they address palliative needs. Initiatives to educate neurologists on the benefits and availability of non-terminal palliative services could improve patient access to this care.

Qualitative study of burnout, career satisfaction, and well-being among US neurologists in 2016

OBJECTIVE

To understand the experience and identify drivers and mitigating factors of burnout and well-being among US neurologists.

METHODS

Inductive data analysis was applied to free text comments (n = 676) from the 2016 American Academy of Neurology survey of burnout, career satisfaction, and well-being.

RESULTS

Respondents providing comments were significantly more likely to be older, owners/partners of their practice, solo practitioners, and compensated by production than those not commenting. The 4 identified themes were (1) policies and people affecting neurologists (government and insurance mandates, remuneration, recertification, leadership); (2) workload and work-life balance (workload, electronic health record [EHR], work-life balance); (3) engagement, professionalism, work domains specific to neurology; and (4) solutions (systemic and individual), advocacy, other. Neurologists mentioned workload > professional identity > time spent on insurance and government mandates when describing burnout. Neurologists' patient and clerical workload increased work hours or work brought home, resulting in poor work-life balance. EHR and expectations of high patient volumes by administrators impeded quality of patient care. As a result, many neurologists reduced work hours and call provision and considered early retirement.

CONCLUSIONS

Our results further characterize burnout among US neurologists through respondents' own voices. They clarify the meaning respondents attributed to ambiguous survey questions and highlight the barriers neurologists must overcome to practice their chosen specialty, including multiple regulatory hassles and increased work hours. Erosion of professionalism by external factors was a common issue. Our findings can provide strategic direction for advocacy and programs to prevent and mitigate neurologist burnout and promote well-being and engagement.

Treatable inherited rare movement disorders

There are many rare movement disorders, and new ones are described every year. Because they are not well recognized, they often go undiagnosed for long periods of time. However, early diagnosis is becoming increasingly important. Rapid advances in our understanding of the biological mechanisms responsible for many rare disorders have enabled the development of specific treatments for some of them. Well-known historical examples include Wilson disease and dopa-responsive dystonia, for which specific and highly effective treatments have life-altering effects. In recent years, similarly specific and effective treatments have been developed for more than 30 rare inherited movement disorders. These treatments include specific medications, dietary changes, avoidance or management of certain triggers, enzyme replacement therapy, and others. This list of treatable rare movement disorders is likely to grow during the next few years because a number of additional promising treatments are actively being developed or evaluated in clinical trials. © 2017 International Parkinson and Movement Disorder Society.

Treatment gaps in Parkinson’s disease care in the Philippines

Neurological services and resources are scarce in low-income and developing countries, such as the Philippines. We looked into the treatment gaps in Parkinson’s disease (PD) care in the Philippines in the following areas: epidemiology, healthcare, financial coverage, pharmacotherapy, surgical treatment and manpower. We collected relevant data on the above-mentioned areas. There is no available Philippine data on PD prevalence. Philippine healthcare is paid through user fees at the point of service. The average consultation fee in Manila ranges from US$10.57–31.74. The average minimum daily wage is US$9.39–10.17. Philippine healthcare is devolved to the local government units. Deep brain stimulation surgery is only available in Manila. Most PD medications are available in the Philippines. There are only nine movement disorder specialists for a population of 100.98 million. Gaps and challenges in PD care in the Philippines still exist.

Burnout, career satisfaction, and well-being among US neurologists in 2016

OBJECTIVE

To study prevalence of and factors that contribute to burnout, career satisfaction, and well-being in US neurologists.

METHODS

A total of 4,127 US American Academy of Neurology member neurologists who had finished training were surveyed using validated measures of burnout, career satisfaction, and well-being from January 19 to March 21, 2016.

RESULTS

Response rate was 40.5% (1,671 of 4,127). Average age of participants was 51 years, with 65.3% male and nearly equal representation across US geographic regions. Approximately 60% of respondents had at least one symptom of burnout. Hours worked/week, nights on call/week, number of outpatients seen/week, and amount of clerical work were associated with greater burnout risk. Effective support staff, job autonomy, meaningful work, age, and subspecializing in epilepsy were associated with lower risk. Academic practice (AP) neurologists had a lower burnout rate and higher rates of career satisfaction and quality of life than clinical practice (CP) neurologists. Some factors contributing to burnout were shared between AP and CP, but some risks were unique to practice setting. Factors independently associated with profession satisfaction included meaningfulness of work, job autonomy, effectiveness of support staff, age, practicing sleep medicine (inverse relationship), and percent time in clinical practice (inverse relationship). Burnout was strongly associated with decreased career satisfaction.

CONCLUSIONS

Burnout is common in all neurology practice settings and subspecialties. The largest driver of career satisfaction is the meaning neurologists find in their work. The results from this survey will inform approaches needed to reduce burnout and promote career satisfaction and well-being in US neurologists.

The Profile of Long-term Parkinson's Disease Survivors with 20 Years of Disease Duration and Beyond

BACKGROUND

Parkinson's disease (PD) patients with 20 years or more survival (PD-20) are not well characterized.

OBJECTIVE

To evaluate PD-20 patient characteristics and identify areas for improvement of their health care.

METHODS

The international, multicenter National Parkinson's Foundation Quality Improvement Initiative (NPF-QII) study database was queried to identify PD-20 subjects. Demographic and clinical data were analyzed.

RESULTS

We identified 187 PD-20 subjects (55% men) representing 4% (187/4,619) of all NPF-QII participants. Subjects were mean age 69.5 years; mean age at PD onset was 44.0 years. The majority (75% ) had 20-25 years of PD duration, the longest duration being 49 years. They were median Hoehn and Yahr stage 3, and 75% had motor fluctuations. Half (54% ) reported exercising. The majority (89% ) were living at home and required a caregiver (88% ). They were mildly cognitively impaired for age (Montreal Cognitive Assessment estimate 22.6±3.7), with most deficits in verbal fluency and delayed recall. Quality of life (Parkinson's Disease Quality of Life Questionnaire index 36±15% ) was mild to moderately impaired, with most impairment in mobility and activities of daily living. Caregiver strain measured by the Multidimensional Caregiver Strain Index (27±16% ), recorded highest subscores in social constraint. PD-20 subjects aged <70 years versus ≥70 only differed significantly by worse cognition (P <  0.0001).

CONCLUSIONS

PD-20 subjects reflect an elite group of PD survivors with early-onset disease and relatively mild cognitive disability despite long disease duration. Interventions for caregivers, mobility, and activities of daily living are areas that could improve caregiver burden and patient quality of life.

A randomized clinical trial of high-dosage coenzyme Q10 in early Parkinson disease: no evidence of benefit

IMPORTANCE

Coenzyme Q10 (CoQ10), an antioxidant that supports mitochondrial function, has been shown in preclinical Parkinson disease (PD) models to reduce the loss of dopamine neurons, and was safe and well tolerated in early-phase human studies. A previous phase II study suggested possible clinical benefit.

OBJECTIVE

To examine whether CoQ10 could slow disease progression in early PD.

DESIGN, SETTING, AND PARTICIPANTS

A phase III randomized, placebo-controlled, double-blind clinical trial at 67 North American sites consisting of participants 30 years of age or older who received a diagnosis of PD within 5 years and who had the following inclusion criteria: the presence of a rest tremor, bradykinesia, and rigidity; a modified Hoehn and Yahr stage of 2.5 or less; and no anticipated need for dopaminergic therapy within 3 months. Exclusion criteria included the use of any PD medication within 60 days, the use of any symptomatic PD medication for more than 90 days, atypical or drug-induced parkinsonism, a Unified Parkinson's Disease Rating Scale (UPDRS) rest tremor score of 3 or greater for any limb, a Mini-Mental State Examination score of 25 or less, a history of stroke, the use of certain supplements, and substantial recent exposure to CoQ10. Of 696 participants screened, 78 were found to be ineligible, and 18 declined participation.

INTERVENTIONS

The remaining 600 participants were randomly assigned to receive placebo, 1200 mg/d of CoQ10, or 2400 mg/d of CoQ10; all participants received 1200 IU/d of vitamin E.

MAIN OUTCOMES AND MEASURES

Participants were observed for 16 months or until a disability requiring dopaminergic treatment. The prospectively defined primary outcome measure was the change in total UPDRS score (Parts I-III) from baseline to final visit. The study was powered to detect a 3-point difference between an active treatment and placebo.

RESULTS

The baseline characteristics of the participants were well balanced, the mean age was 62.5 years, 66% of participants were male, and the mean baseline total UPDRS score was 22.7. A total of 267 participants required treatment (94 received placebo, 87 received 1200 mg/d of CoQ10, and 86 received 2400 mg/d of CoQ10), and 65 participants (29 who received placebo, 19 who received 1200 mg/d of CoQ10, and 17 who received 2400 mg/d of CoQ10) withdrew prematurely. Treatments were well tolerated with no safety concerns. The study was terminated after a prespecified futility criterion was reached. At study termination, both active treatment groups showed slight adverse trends relative to placebo. Adjusted mean changes (worsening) in total UPDRS scores from baseline to final visit were 6.9 points (placebo), 7.5 points (1200 mg/d of CoQ10; P = .49 relative to placebo), and 8.0 points (2400 mg/d of CoQ10; P = .21 relative to placebo).

CONCLUSIONS AND RELEVANCE

Coenzyme Q10 was safe and well tolerated in this population, but showed no evidence of clinical benefit.

Movement disorders in pregnancy

PURPOSE OF REVIEW

This review discusses movement disorders that occur during pregnancy, the treatment of preexisting movement disorders, and the influence the pregnant state has on movement disorders symptoms, in order to guide clinicians in providing better counseling for female patients who are pregnant or considering pregnancy.

RECENT FINDINGS

Unique considerations for movement disorders during pregnancy include investigations and their safety during pregnancy and the impact of treatment on both the pregnant patient and her fetus.

SUMMARY

The most common movement disorders arising in pregnancy are restless leg syndrome and chorea gravidarum. Preexisting movement disorders in women who become pregnant may also be seen.
