Neurologist ambulatory care, health care utilization, and costs in a large commercial dataset

Determining the impact of specialized care on health outcomes and health care utilization in Parkinsonism

BACKGROUND

Although care of Parkinsonism (PKM) is assumed to be optimally provided by movement disorder neurologists within an interdisciplinary clinic model, there is a paucity of published data to support this.

OBJECTIVES

To investigate the impact of movement disorder neurologist care of individuals with Parkinsonism (PKM).

METHODS

A retrospective exposure design was adopted using administrative data. Incident PKM individuals were identified in billing claims. A nine-year exposure period to movement disorder neurologist, general neurologist and non-neurologist care was calculated based on the billing codes. Regression models were used to test the association of provider exposure on time to death and long-term care (LTC) admission. Linear models were used to test varying provider exposure and hospital admissions, hospital days and emergency department visits.

RESULTS

1914 incident individuals were identified. There was no difference in PKM mortality, emergency visits, hospital admissions, or hospital days between providers, however exposure to general neurology and non-neurology care was associated with a significantly higher risk of admission to LTC compared to movement disorder neurologist care (HR 1.43; 95% CI 1.09-1.87 for general neurology (p-value = 0.0089); HR 1.61; 95% CI 1.25-2.05 for non-neurology (p-value = 0.0002), respectively.

CONCLUSION

Movement disorder neurologist care is associated with a lower risk of admission to LTC over general neurologist care in individuals with PKM.

High-Yield, Case-Based, Interactive Workshop on Telehealth and Teleneurology With Pediatric Resident Physicians

Introduction

Increasing prevalence of neurologic disorders with an aging global population and limited availability of neurologists may lead to worse patient outcomes. As a result of the COVID-19 pandemic, telehealth services surged, and despite easing public health measures, the demand has remained. Telehealth technology has the potential to close the physical gaps in expanding the reach of care. This academic half-day workshop sought to provide a learning opportunity in response to these concerns.

Methods

The workshop consisted of small- and large-group case discussions among pediatric resident physicians (PGY 1-PGY 3) moderated by two child neurology faculty physicians over Zoom. Participants received a learner document with prereading articles and questions for each case. PowerPoint presentations with video demonstrations were used to introduce the cases and guide discussions.

Results

Of the 25 attendees, 14 (56% response rate) answered a nonmandatory postsession survey. Eighty-six percent of the respondents were very or extremely satisfied with the content covered and were similarly satisfied with the effectiveness of content delivery. Seventy-nine percent of the respondents found the content helpful or very helpful in preparation for the board, and 93% anticipated applying the content covered occasionally or frequently in their clinical practice.

Discussion

Small-group discussions with video demonstrations are helpful in increasing proficiency with telehealth technology and in examining board-relevant cases on pediatric patients. There is strong interest in subsequent telehealth half-day workshops that incorporate teaching through group discussions on relevant patient case scenarios.

Evaluating the impact of patient-reported outcome measures on depression and anxiety levels in people with multiple sclerosis: a study protocol for a randomized controlled trial

BACKGROUND

Multiple sclerosis (MS) is a chronic disease affecting multiple functional aspects of patients' lives. Depression and anxiety are common amongst persons with MS (PwMS). There has been an interest in utilizing patient-reported outcome measures (PROMs) to capture and systematically assess patient's perceptions of their MS experience in addition to other clinical measures, but PROMs are not usually collected in routine clinical practice. Therefore, this study aims to systematically incorporate periodic electronically administered PROMs into the care of PwMS to evaluate its effects on depression and anxiety.

METHODS

A randomized controlled trial will be conducted with patients allocated 1:1 to either intervention or conservative treatment groups. Patients in the intervention group will complete PROMs at the start of the study and then every 6 months for 1 year, in addition to having their MS healthcare provider prompted to view their scores. The conservative treatment group will complete PROMs at the start of the study and again after 12 months, and their neurologist will not be able to view their scores. For both groups, pre-determined critical PROM scores will trigger an alert to the patient's MS provider. The difference in change in Hospital Anxiety and Depression Scale score between the intervention and conservative treatment groups at 12 months will be the primary outcome, along with difference in Consultation Satisfaction Questionnaire and CollaboRATE scores at 12 months, and proportion and type of healthcare provider intervention/alerts initiated by different PROMs as secondary outcomes.

DISCUSSION

This study will determine the feasibility of utilizing PROMs on an interval basis and its effects on the psychological well-being of PwMS. Findings of this study will provide evidence on use of PROMs in future MS clinical practice.

TRIAL REGISTRATION

This trial is registered at the National Institutes of Health United States National Library of Medicine, ClinicalTrials.gov NCT04979546 . Registered on July 28, 2021.

Depression After Parkinson's Disease: Treated Differently or Not At All?

Depression is a common, potentially debilitating non-motor symptom of Parkinson's disease which may manifest at any time and can respond to treatment. Although depression is a known primary mediator of health-related quality of life, it is currently unknown whether the timing of depression diagnosis relative to PD diagnosis affects receipt of depression treatment. Electronic health record data were examined to explore differences in depression treatment among patients diagnosed with depression before or after PD diagnosis. Compared to PD patients diagnosed with depression prior to PD, those diagnosed with depression following PD are less likely to receive any treatment, either pharmacologic or non-pharmacologic, indicating a temporal association between the time of PD diagnosis and receipt of depression treatment. This highlights a potentially substantial treatment gap, despite the existence of efficacious treatment. Diagnosis with PD appears to alter depression treatment and further research is warranted to determine potential causes and effective interventions.

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.

Longitudinal Healthcare Utilization and Costs in Parkinson's Disease: Pre-Diagnosis to 9 Years After

BACKGROUND

There is currently insufficient long-term data on costs of treatment in patients with Parkinson's disease (PD), which is chronic and progressive, and associated with substantial healthcare costs. Identifying patterns in healthcare utilization and cost may illuminate further discussion on early intervention.

OBJECTIVE

To characterize long-term healthcare utilization and costs of PD in newly diagnosed patients managed by movement disorder specialists.

METHODS

Using a longitudinal matched-cohort study of linked data from the National Neuroscience Institute Parkinson's disease and Movement Disorder and healthcare administrative databases in Singapore from 2008-2017, we compared healthcare utilization and costs between patients and controls matched on age, sex, race, and Charlson Comorbidity Index score.

RESULTS

1,162 patients met study inclusion criteria and 1,157 matched controls were identified. The total mean annual healthcare cost (at 2017 costs) was significantly increased in patients compared to controls from years 1-9 post-diagnosis. The increased cost was observed 2 years before diagnosis (USD2322 vs. 2052; p < 0.001). Mean annual cost attributable to PD increased from USD1854 at 1-year post-diagnosis to USD2652 at 9 years. Over 9 years, average costs were significantly higher across all domains of healthcare utilization except primary care-cost of intermediate and long-term care was increased by a factor of 2.5, specialist care by 2.3, emergency department visits by 1.6, and hospital admissions by 1.3.

CONCLUSION

PD results in higher healthcare utilization and costs. Pre-diagnosis increase in healthcare utilization observed in patients supports the presence of prodromal PD symptoms and may present an opportunity for early diagnosis.

The neuropalliative multidisciplinary team-Members and their roles

Neurodegenerative conditions are prominent contributors to both morbidity and mortality worldwide. They pose a significant challenge to health professionals, health systems, and the often unpaid, untrained family members and carers. The many and varied challenges encountered are best managed by a multidisciplinary neuropalliative team, as it is impossible for a single clinician to possess and deliver the wide range of skills and services required to optimally care for these patients. This chapter discusses the assembly, maintenance, and care of such a team, as well as potential difficulties and solutions in domains such as funding, training, geographical remoteness, as well as the potential lack of awareness and acceptance by colleagues. A comprehensive description of the role of all possible team members is discussed. The chapter outlines the concept, content, and potential benefits of a multidisciplinary team in neuropalliative care. Its thesis is twofold: that multidisciplinary care is vital and, second, that the sum of the whole of a team can be greater than the individual parts with respect to organization, planning, experience, and creativity of approach. With all these factors considered, and implemented wherever possible, we may all move closer to optimizing the comfort and care of our shared neuropalliative patients.

Antiseizure medication adherence trajectories in Medicare beneficiaries with newly treated epilepsy

OBJECTIVE

This study was undertaken to characterize trajectories of antiseizure medication (ASM) adherence in adults with newly treated epilepsy and to determine predictors of trajectories.

METHODS

This was a retrospective cohort study using Medicare. We included beneficiaries with newly treated epilepsy (one or more ASM and none in the preceding 2 years, plus International Classification of Diseases codes) in 2010-2013. We calculated the proportion of days covered (proportion of total days with any ASM pill supply) for 8 quarters or until death. Group-based trajectory models characterized and determined predictors of trajectories.

RESULTS

We included 24 923 beneficiaries. Models identified four groups: early adherent (60%), early nonadherent (18%), late adherent (11%), and late nonadherent (11%). Numerous predictors were associated with being in the early nonadherent versus early adherent group: non-White race (e.g., Black, odds ratio [OR] = 1.7, 95% confidence interval [CI] = 1.5-1.8), region (e.g., South vs. Northeast: OR = 1.2, 95% CI = 1.1-1.4), and once daily initial medication (OR = 1.1, 95% CI = 1.0-1.3). Predictors associated with decreased odds of being in the early nonadherent group included older age (OR = .9 per decade, 95% CI = .9-.9), female sex (OR = .9, 95% CI = .8-1.0), full Medicaid eligibility (OR = .6, 95% CI = .4-.8), neurologist visit (OR = .6, 95% CI = .6-.7), and initial older generation ASM (OR = .6, 95% CI = .6-.7).

SIGNIFICANCE

We identified four ASM adherence trajectories in individuals with newly treated epilepsy. Whereas risk factors for early nonadherence such as race or geographic region are nonmodifiable, our work highlighted a modifiable risk factor for early nonadherence: lacking a neurologist. These data may guide future interventions aimed at improving ASM adherence, in terms of both timing and target populations.

COVID-19 social distancing: negative effects on people with Parkinson disease and their associations with confidence for self-management

BACKGROUND

The purpose of this study was to describe the effects of COVID-19 social distancing on the function, health, and well-being of people with Parkinson disease (PD), and test the association of these effects with patients' activation levels, i.e., their skills and confidence in managing their health.

METHODS

Community-dwelling individuals with PD answered an anonymous web-based survey. Part 1 included 27 multiple-choice questions regarding changes in function, health, medical care, and well-being. Part 2 consisted of the Patient Activation Measure, which enquired about skills and confidence in managing one's health.

RESULTS

Respondents (N = 142) reported decreases in various function (24.8%-37.3%), health (33.8%-43%), and well-being (26.1%-47.1%) domains. Rehabilitation ceased for 61.2%. Among those reporting a worsening of health, 67.8% associated this with the cessation of rehabilitative treatments or decrease in physical activity. Patients' activation levels were inversely correlated with increased assistance for activities of daily living, increased tiredness, worsening symptoms, and lack of support from family and friends.

CONCLUSIONS

Social distancing had a major negative impact on the health and function of people with PD.

PRACTICAL IMPLICATIONS

Supporting people with PD skills and confidence in managing health may preserve their physical and mental health during this period of dramatic changes in life's circumstances.

Markers of Quality Care for Newly Diagnosed People With Epilepsy on Medicaid

BACKGROUND

For newly diagnosed people with epilepsy (PWE), proper treatment is important to improve outcomes, yet limited data exist on markers of quality care.

OBJECTIVE

Examine markers of quality care for newly diagnosed PWE.

METHODS

Using Medicaid claims data (2010-2014) for 15 states we identified adults 18-64 years of age diagnosed with incident epilepsy in 2012 or 2013. We built 5 sequential logistic regression models to evaluate: (1) seeing a neurologist; (2) diagnostic evaluation; (3) antiepileptic medication adherence; (4) serum drug levels checked; and (5) being in the top quartile of number of negative health events (NHEs). We adjusted for demographics, comorbidities, county-level factors, and the outcomes from all prior models.

RESULTS

Of 25,663 PWE, 37.3% saw a neurologist, with decreased odds for those of older age, those residing in counties with low-density of neurologists, and certain race/ethnicities; about 57% of PWE received at least 1 diagnostic test; and nearly 62% of PWE were adherent to their medication. The most common comorbidities were hypertension (37.1%) and psychoses (26.9%). PWE with comorbidities had higher odds of seeing a neurologist and to have NHEs. Substance use disorders were negatively associated with medication adherence and positively associated with high NHEs.

CONCLUSIONS

There are notable differences in demographics among people with incident epilepsy who do or do not see a neurologist. Differences in NHEs persist, even after controlling for neurologist care and diagnostic evaluation. Continued attention to these disparities and comorbidities is needed in the evaluation of newly diagnosed PWE.

Telemedicine as support for primary care referrals to neurologists: decision-making between different specialists when guiding the case over the phone

BACKGROUND

Brazil's public health system, the largest in the world, faces great challenges in establishing access to specialized care for all Brazilians. "Regula Mais Brasil" is a structuring project from the Ministry of Health that aims to optimize the referral process for specialized care throughout Brazil and uses telemedicine to support primary care physicians. The high demand for support and referrals in the neurology specialty raises questions about what the difficulties and doubts in managing these patients are and whether the training of the coordinating physician influences the orientation and outcome of referral.

METHODS

In a retrospective analysis on a database, all teleconsultations in the neurology specialty were evaluated. The diagnoses were categorized using the ICD-10 and according to the specialty of the coordinating teleconsultant for multiple comparisons.

RESULTS

In total, 1687 teleconsultations were conducted between January 10 and December 2, 2019, in the cities of Belo Horizonte and Porto Alegre and in the Federal District. The most frequent area of doubt for doctors was about epilepsy. After discussion via telemedicine, 25% of the referrals were avoided and the specialty of the teleconsultant physician did not impact the decision made: 72.3, 72.6 and 66.5%, in relation to approval by neurologists, family doctors and other experts, respectively.

CONCLUSION

Increasing access to specialists, not only for patients but also for doctors, helps in achieving early resolution of issues of greater difficulty for primary healthcare doctors, thus resulting in lower numbers of referrals.

Clustering 5-Year Multidimensional Health Care Trajectory Patterns in Alzheimer's Disease and Related Syndromes

OBJECTIVE

After diagnosis of Alzheimer's disease and related syndromes (ADRS), personalized care adapted to each patient's needs is recommended to provide a care plan and start symptomatic treatments according to guidelines. Over the past decade, dedicated structures and care have been implemented in various settings. Equal access to ADRS care, health care providers and services is crucial to ensure potential health benefits for everyone. However, the extent of use of recommended services and favorable health care utilization trajectories (HUT) may vary according to individual and contextual characteristics. The aim of this article was to (1) describe HUT patterns after multidimensional clustering of similar trajectories, (2) assess the proportion of individuals presenting favorable HUTs, and (3) identify factors associated with favorable HUTs.

DESIGN

Cohort study.

SETTING AND PARTICIPANTS

A cohort of 103,317 people newly diagnosed with ADRS identified in the French health reimbursement system (SNDS) was followed for 5 years with their monthly utilization on 11 health care dimensions.

METHODS

For 3 age groups (65-74, 75-84, ≥85 years), 15 clusters of patients were identified using partitioning around medoids applied to Levenshtein distances. They were qualitatively assessed by pluridisciplinary experts. Individual and contextual determinants of clusters denoting favorable trajectories were identified using mixed random effects multivariable logistic regression models.

RESULTS

Clusters with favorable HUTs denoting slow, progressive trajectories centered on at-home care, represented approximatively 25% of the patients. Determinants of favorable HUTs were mostly individual (age, female gender, absence of certain comorbidities, circumstances of ADRS identification, lower deprivation). Contextual determinants were also identified, in particular accessibility to nurses and nursing homes. Inter-territories variance was small but significant in all age groups (from 0.9% to 1.8%).

CONCLUSION AND IMPLICATIONS

Favorable HUTs remain the minority and many efforts can still be made to improve HUTs. Qualitative studies could help understanding underlying barriers to favorable HUTs.

Non-viral, direct neuronal reprogramming from human fibroblast using a polymer-functionalized nanodot

Among various strategies to treat neurodegenerative disorders, cell replacement therapies have drawn much attention recently. Such a trend led to the increase in demand for the rare and specialized cells, followed by the outburst development of various cell reprogramming strategies. However, several limitations on these conventional methods remain to be solved, including the genetic instability of the viral vectors and the high cytotoxicity or poor performance of the non-viral carriers. Therefore, non-viral methods need to be developed to ensure safe and efficient cell reprogramming. Here, we introduce a polymer-modified nano-reagent (Polymer-functionalized Nanodot, PolyN) for the safe and efficient, non-viral direct cell reprogramming. PolyN facilitated the highly efficient contemporary overexpression of the transgene compared to the conventional reagent. With our nano-reagent, we demonstrated the SOX2-mediated cell reprogramming and successfully generated the neuron-like cell from the human fibroblast.

Burden of Parkinson's Disease by Severity: Health Care Costs in the U.S. Medicare Population

BACKGROUND

Current understanding of the health care costs of Parkinson's disease (PD) and the incremental burden of advanced disease is incomplete.

OBJECTIVES

The aim of this study was to assess the direct economic burden associated with advanced versus mild/moderate PD in a prevalent national sample of elderly U.S. Medicare beneficiaries with a PD diagnosis.

METHODS

Analyzing 100% fee-for-service Medicare claims from 2013, we defined advanced PD with a medication-based algorithm and calculated all-cause and PD-related costs for the overall sample and by disease severity. We measured primary PD-related costs (based on claims with a primary diagnosis of PD) and any PD-related costs (based on claims with PD in any diagnostic field). Generalized linear models were used to estimate risk-adjusted mean cost differences between the advanced and mild/moderate PD groups for the calendar year.

RESULTS

The final sample (N = 144,703) had mean observed all-cause, primary PD-related, and any PD-related costs of $23,041 (SD, $34,045), $3429 (SD, $7431), and $9924 (SD, $22,140), respectively. Twenty percent of patients were classified as advanced PD. Costs varied substantially; any PD-related mean costs were $483 for the lowest patient decile (which included 1% of the advanced group) and $48,145 for the highest decile (which included 15% of the advanced group). Incremental risk-adjusted costs of advanced PD were $5818 (95% confidence interval [CI]: $5411-$6225) for all-cause costs, $3644 (95% CI: $3484-$3806) for primary PD-related costs, and $6088 (95% CI: $5779-$6398) for any PD-related costs.

CONCLUSIONS

Elderly Medicare beneficiaries with PD had substantial variation in PD-related costs. Advanced PD was associated with a larger economic burden than mild/moderate PD. © 2020 International Parkinson and Movement Disorder Society.

A multidisciplinary care model to increase access to neurologic ambulatory care

BACKGROUND

Expert patient care has been associated with improved outcomes for neurology patients, yet timely access to specialists is challenging. The employment of nurse practitioners (NPs) holds great potential to increase access to neurologic ambulatory care, however little practical guidance exists to date for how this may be achieved.

LOCAL PROBLEM

To improve timely care provision for patients with neurologic disease, we employed a multidisciplinary care utilization framework that used NPs to expand clinic appointment availability.

METHODS AND INTERVENTION

After evaluating our baseline performance, we applied a standardized approach to the deployment of NPs in neurology clinic with regard to scheduling clinic sessions and patient appointments. The primary outcome measure was appointment availability measured over 6 months preintervention (June to November 2016) and 6 months postintervention (June to November 2017). Secondary measures included NP effort allocation.

RESULTS

The postintervention period demonstrated an increase in available appointments (3,731 preintervention vs. 4,318 postintervention) and scheduled appointments (2,014 vs. 2,685). Nurse practitioners spent more time practicing at the fullest extent of their licensure. All improvements were accomplished without the hiring of additional staff.

CONCLUSIONS

A multidisciplinary care utilization framework for NP employment across neurology subspecialties resulted in an increase in appointment availability. Furthermore, this model is likely to be sustainable due to provider satisfaction and financial viability.

Claims data analyses unable to properly characterize the value of neurologists in epilepsy care

OBJECTIVE

To determine the association of a neurologist visit with health care use and cost outcomes for patients with incident epilepsy.

METHODS

Using health care claims data for individuals insured by United Healthcare from 2001 to 2016, we identified patients with incident epilepsy. The population was defined by an epilepsy/convulsion diagnosis code (ICD codes 345.xx/780.3x, G40.xx/R56.xx), an antiepileptic prescription filled within the succeeding 2 years, and neither criterion met in the 2 preceding years. Cases were defined as patients who had a neurologist encounter for epilepsy within 1 year after an incident diagnosis; a control cohort was constructed with propensity score matching. Primary outcomes were emergency room (ER) visits and hospitalizations for epilepsy. Secondary outcomes included measures of cost (epilepsy related, not epilepsy related, and antiepileptic drugs) and care escalation (including EEG evaluation and epilepsy surgery).

RESULTS

After participant identification and propensity score matching, there were 3,400 cases and 3,400 controls. Epilepsy-related ER visits were more likely for cases than controls (year 1: 5.9% vs 2.3%, p < 0.001), as were hospitalizations (year 1: 2.1% vs 0.7%, p < 0.001). Total medical costs for epilepsy care, nonepilepsy care, and antiepileptic drugs were greater for cases (p ≤ 0.001). EEG evaluation and epilepsy surgery occurred more commonly for cases (p ≤ 0.001).

CONCLUSIONS

Patients with epilepsy who visited a neurologist had greater subsequent health care use, medical costs, and care escalation than controls. This comparison using administrative claims is plausibly confounded by case disease severity, as suggested by higher nonepilepsy care costs. Linking patient-centered outcomes to claims data may provide the clinical resolution to assess care value within a heterogeneous population.

Innovative approaches reaching underserved and rural communities to improve epilepsy care: A review of the methodology of the Connectors Project

OBJECTIVE

The Connectors Project, a collaboration between the Epilepsy Foundation and UCB Pharma, was a multiyear project designed to improve epilepsy care in underserved communities. A core objective of the Connectors Project was to pilot new and innovative approaches to epilepsy awareness and education in rural and underserved areas, including standardized curricula for healthcare providers and patients.

METHODS

A series of consensus conferences explored opportunities and barriers to epilepsy care throughout the United States including access to local Epilepsy Foundations, neurologists, and epilepsy centers. Data from QuintilesIMS™ were examined for access to newer antiepileptic drugs (AEDs)-a proxy for quality of epilepsy care-in different regions. State factors (e.g., local epilepsy foundation office, access to newer vs. older AEDs, and geographic density and diversity) were used in selecting four states as examples of rural and underserved areas to pilot the awareness and educational programs. For each state, a work team assessed challenges and opportunities, tailored educational curricula, and developed strategies for effective delivery of the educational programs. Interventions were held between June 2016 and June 2017. Interventions consisted of outreach and awareness programs, in-person health education to healthcare providers and patients/families, and digital health education.

RESULTS

Michigan, Nevada, Oklahoma, and West Virginia were identified as pilot states representing geographically diverse areas, ranging from a state with a large high-density population center with several epilepsy centers and a local Epilepsy Foundation office (Michigan) to a state with predominately rural areas and a few small urban cores, two epilepsy centers, and no in-state Epilepsy Foundation office (West Virginia). State work teams tailored interventions and examined options for type, intent, ease of use, and impact. All states implemented outreach and awareness initiatives and in-person health education for patients and healthcare providers; use of digital health education was variable. Measurement of the interventions was agreed to be performed by the use of patient and physician surveys and reevaluation of data from QuintilesIMS for access to newer AEDs.

CONCLUSION

Local Epilepsy Foundation offices successfully connected healthcare providers in rural and underserved areas to epilepsy education designed to enhance quality care in epilepsy. Educational opportunities for people with epilepsy and their families addressed critical gaps in accessing quality epilepsy care and self-management. Tailored and innovative educational approaches can be used to increase awareness levels and to overcome geographic challenges in reaching underserved populations. Relationship building and repeated, consistent engagement with healthcare providers and patients can assist in improving communication and self-management skills among patients with epilepsy.

Neurologic and neuroscience education

Neurologic disorders are among the most frequent causes of morbidity and mortality in the United States. Moreover, the current shortfall of neurologists is expected to worsen over the coming decade. As a consequence, many patients with neurologic disorders will be treated by physicians and primary care providers without formal neurologic training. Furthermore, a pervasive and well-described fear of neurology, termed neurophobia, has been identified in medical student cohorts, residents, and among general practitioners. In this article, members of the American Academy of Neurology A.B. Baker Section on Neurological Education review current guidelines regarding neurologic and neuroscience education, contextualize the genesis and the negative consequences of neurophobia, and provide strategies to mitigate it for purposes of mentoring future generations of health care providers.

Demand for neurological services in Central Eastern Europe: a 10-year national survey in Hungary

BACKGROUND AND PURPOSE

In order to plan neurological capacities at a national level for the next decade, the current use of neurological services should be evaluated. We analyzed the utilization of neurological services in Hungary, a country with a single-payer health insurance system covering the whole population.

METHODS

We created a database from medical reports submitted to the National Health Insurance Fund from all hospitals and outpatient services between 2004 and 2013. The number of subjects presenting to the neurological healthcare system and their major diagnoses by 10th International Classification of Diseases categories were analyzed. The overall healthcare service utilization of these patients was also estimated.

RESULTS

Of the 10 million inhabitants, 2.9 million people used an inpatient or outpatient neurological service at least once over the 10-year period. Annually, 1% of the population was admitted to neurological inpatient wards and 6% of the population used some neurological outpatient service. Major reasons for using neurological services were: cerebrovascular diseases (I60-I69; 1.2 million patients), episodic and paroxysmal disorders (G40-G47; 1.3 million patients) and general symptoms and signs (R50-R56; 1.3 million patients). The 2.9 million people had 12.7 million hospital admissions to any ward and 365.7 million outpatient visits to any specialist during the 10 years.

CONCLUSIONS

The demand for neurological services is high in Hungary; close to 30% of the population used an inpatient or outpatient neurological service at least once during this 10-year period. Results from this project provide data for international comparisons and help to ensure better informed and more focused resource allocation.

Expanding incentives for coordinated, patient-centered care: Implications for neurologists

Historically, payment for cognitive, nonprocedural care has required provision of face-to-face evaluation and management as part of general ambulatory or inpatient care. Although non-face-to-face patient care (e.g., care via electronic means or telephone) is commonly performed and is integral to patient-centered care, appropriate reimbursement for this type of care is lacking. Beginning in 2017, Centers for Medicare and Medicaid (CMS) has taken a large step forward in reimbursing an increased number of cognitive care and non-face-to-face codes. CMS has also included language indicating that nonphysician providers (i.e., nurse practitioners and physician assistants) can perform many of these services independently. The 2017 and now the 2018 fee schedules thus create new payments for non-face-to-face, patient-centered services, and may allow neurologists to reach out to more patients through nonphysician providers. As health care in the United States moves toward value-based incentives, these newly supported non-face-to-face services will provide neurologists with new tools to deliver sustainable, high-value care.

Association of neurologist care with headache expenditures: A population-based, longitudinal analysis

Objective To assess the association of neurologist ambulatory care with healthcare utilization and expenditure in headache. Methods This was a longitudinal cohort study from two-year duration panel data, pooled from 2002-2013, of adult respondents identified with diagnostic codes for headache in the Medical Expenditure Panel Survey. Those with a neurologist ambulatory care visit in year one of panel participation were compared with those who did not for the change in annual aggregate direct headache-related health care costs from year one to year two of panel participation, inflated to 2015 US dollars. Results were adjusted via multiple linear regression for demographic and clinical variables, utilizing survey variables for accurate estimates and standard errors. Results Eight hundred and eighty-seven respondents were included, with 23.3% (207/887) seeing a neurologist in year one. The neurologist group had higher year-one mean headache-related expenditures ($3032 vs. $1636), but nearly equal mean year-two expenditures compared to controls ($1900 vs. $1929). Adjusted association between neurologist care and difference in mean annual expenditures from year two to year one was -$1579 (95% CI -$2468, -$690, p < 0.001). Conclusion Among headache sufferers, particularly those with higher headache-related healthcare expenditures, neurologist care is associated with a significant reduction in costs over two years.

Mendelian Disease Associations Reveal Novel Insights into Inflammatory Bowel Disease

Background

Monogenic diseases have been shown to contribute to complex disease risk and may hold new insights into the underlying biological mechanism of Inflammatory Bowel Disease (IBD).

Methods

We analyzed Mendelian disease associations with IBD using over 55 million patients from the Optum's deidentified electronic health records dataset database. Using the significant Mendelian diseases, we performed pathway enrichment analysis and constructed a model using gene expression datasets to differentiate Crohn's disease (CD), ulcerative colitis (UC), and healthy patient samples.

Results

We found 50 Mendelian diseases were significantly associated with IBD, with 40 being significantly associated with both CD and UC. Our results for CD replicated those from previous studies. Pathways that were enriched consisted of mainly immune and metabolic processes with a focus on tolerance and oxidative stress. Our 3-way classifier for UC, CD, and healthy samples yielded an accuracy of 72%.

Conclusions

Mendelian diseases that are significantly associated with IBD may reveal novel insights into the genetic architecture of IBD.

Neuroimaging utilization and findings in headache outpatients: Significance of red and yellow flags

Background

Neuroimaging for headache commonly exceeds published guideline recommendations and may be overutilized.

Methods

We conducted a retrospective cross-sectional study of all outpatient community patients at Mayo Clinic Rochester who underwent a neuroimaging study for a headache indication in 2015. We assessed the neuroimaging utilization pattern, clinical application of red flags, and concordance with neuroimaging guidelines.

Results

We identified 190 outpatients who underwent 304 neuroimaging studies for headache. The median age was 46.5 years (range 18–91 years), 65% were female, and most reported no prior history of headache (n = 97, 51%). A minority of patients had prior brain imaging studies (n = 44, 23%) and neurological consultations for headache (n = 29, 15%). Few studies were ordered after consultation with a neurologist (n = 14, 7%). Seventy-seven percent of patients were documented to have a “red flag” justifying the imaging study. Abnormal neuroimaging findings were found in 3.1% of patients with warning flags (5/161); carotid dissection (n = 3) and reversible cerebral vasoconstrictive syndrome (n = 2). An estimated 35% of patients were imaged against guidelines.

Conclusions

The prevalence of serious causes of headache in a community practice was low despite the presence of a documented red flag symptom. Inadequate understanding or application of red flags may be contributing to recommendations to image patients against current guidelines. Interventions to reduce unnecessary neuroimaging of patients with headache need to be designed and implemented.

The association of neurologists with headache health care utilization and costs

OBJECTIVE

To determine the association of a neurologist visit with headache health care utilization and costs.

METHODS

Utilizing a large privately insured health care claims database, we identified patients with an incident headache diagnosis (ICD-9 codes 339.xx, 784.0x, 306.81) with at least 5 years follow-up. Patients with a subsequent neurologist visit were matched to controls without a neurologist visit using propensity score matching, accounting for 54 potential confounders and regional variation in neurologist density. Co-primary outcomes were emergency department (ED) visits and hospitalizations for headache. Secondary outcomes were quality measures (abortive, prophylactic, and opioid prescriptions) and costs (total, headache-related, and non-headache-related). Generalized estimating equations assessed differences in longitudinal outcomes between cases and controls.

RESULTS

We identified 28,585 cases and 57,170 controls. ED visits did not differ between cases and controls (p = 0.05). Hospitalizations were more common in cases in year 0-1 (0.2%, 95% confidence interval [CI] 0.2%-0.3% vs 0.01%, 95% CI 0.01%-0.02%; p < 0.01), with minimal differences in subsequent years. Costs (including non-headache-related costs) and high-quality and low-quality medication utilization were higher in cases in the first year and decreased toward control costs in subsequent years with small differences persisting over 5 years. Opioid prescriptions increased over time in both cases and controls.

CONCLUSION

Compared with those without a neurologist, headache patients who visit neurologists had a transient increase in hospitalizations, but the same ED utilization. Confounding by severity is the most likely explanation given the non-headache-related cost trajectory. Claims-based risk adjustment will likely underestimate disease severity of headache patients seen by neurologists.

Racial disparities in neurologic health care access and utilization in the United States

OBJECTIVE

To evaluate racial and ethnic differences in the utilization of neurologic care across a wide range of neurologic conditions in the United States.

METHODS

We analyzed nationally representative data from the 2006-2013 Medical Expenditure Panel Survey (MEPS), including information on demographics, patient-reported health conditions, neurology visit rates, and costs. Using diagnostic codes, we identified persons with any self-identified neurologic disorder except back pain, as well as 5 subgroups (Parkinson disease, multiple sclerosis, headache, cerebrovascular disease, and epilepsy). To assess disparities in neurologic care utilization, we performed logistic regression analyses of outpatient department neurologic care visit rates and expenditures for each racial ethnic group controlling for age, sex, health status, socioeconomic characteristics, and geographic region of care.

RESULTS

Of the 279,103 MEPS respondents, 16,936 (6%) self-reported a neurologic condition; 5,890 (2%) received a total of 13,685 outpatient neurology visits. Black participants were nearly 30% less likely to see an outpatient neurologist (odds ratio [OR] 0.72, confidence interval [CI] 0.64-0.81) relative to their white counterparts, even after adjustment for demographic, insurance, and health status differences. Hispanic participants were 40% less likely to see an outpatient neurologist (OR 0.61, CI 0.54-0.69). Among participants with known neurologic conditions, blacks were more likely to be cared for in the emergency department, to have more hospital stays, and to have higher per capita inpatient expenditures than their white counterparts.

CONCLUSIONS

Our findings highlight racial and ethnic inequalities in the utilization of neurologic care in the United States.

Trends in surgical treatment of Chiari malformation Type I in the United States

OBJECTIVE The goal of this analysis was to define temporal and geographic trends in the surgical treatment of Chiari malformation Type I (CM-I) in a large, privately insured health care network. METHODS The authors examined de-identified insurance claims data from a large, privately insured health care network of over 58 million beneficiaries throughout the United States for the period between 2001 and 2014 for all patients undergoing surgical treatment of CM-I. Using a combination of International Classification of Diseases (ICD) diagnosis codes and Current Procedural Terminology (CPT) codes, the authors identified CM-I and associated diagnoses and procedures over a 14-year period, highlighting temporal and geographic trends in the performance of CM-I decompression (CMD) surgery as well as commonly associated procedures. RESULTS There were 2434 surgical procedures performed for CMD among the beneficiaries during the 14-year interval; 34% were performed in patients younger than 20 years of age. The rate of CMD increased 51% from the first half to the second half of the study period among younger patients (p < 0.001) and increased 28% among adult patients between 20 and 65 years of age (p < 0.001). A large sex difference was noted among adult patients; 78% of adult patients undergoing CMD were female compared with only 53% of the children. Pediatric patients undergoing CMD were more likely to be white with a higher household net worth. Regional variability was identified among rates of CMD as well. The average annual rate of surgery ranged from 0.8 surgeries per 100,000 insured person-years in the Pacific census division to 2.0 surgeries per 100,000 insured person-years in the East South Central census division. CONCLUSIONS Analysis of a large nationwide health care network showed recently increasing rates of CMD in children and adults over the past 14 years.

Improved availability and quality of care with epilepsy nurse practitioners

BACKGROUND

This study investigated the quality of care delivered by nurse practitioner (NP)-physician teams employed to expand clinic appointment availability for patients with epilepsy.

METHODS

We performed a retrospective observational cohort study of patients with epilepsy presenting to the Penn Epilepsy Center for a new patient appointment in 2014. During this time, patients were seen either by an NP-physician team care model or a more traditional physician-only care model. These care models were compared with regard to adherence to the 2014 American Academy of Neurology epilepsy quality measures at the initial visit. Clinical outcomes of seizure frequency, presentations to the Emergency Department, injury, and death were assessed over the subsequent year.

RESULTS

A total of 169 patients were identified by our inclusion and exclusion criteria: 65 patients in the NP-physician team care model cohort and 104 patients in the physician-only care model cohort. The NP-physician team care model saw, on average, 3 more patients per clinic session. There were no meaningful differences between these cohorts in baseline characteristics. The NP-physician team care model showed equivalent adherence to the physician-only care model for the epilepsy quality measures, with superior adherence to the counseling measures of querying for side effects, provision of personalized epilepsy safety education, and screening for behavioral health disorders. The 2 care models performed similarly in all clinical outcomes.

CONCLUSIONS

An NP-physician team care model employed to increase availability of care could also improve quality of care delivered.

Ambulatory training in neurology education

Much of the care provided by practicing neurologists takes place in outpatient clinics. However, neurology trainees often have limited exposure to this setting. Adequate incorporation of outpatient care in neurology training is vital; however it is often hampered by numerous challenges. We detail a number of these challenges and suggest potential means for improvement.

Introducing the Axon Registry: An opportunity to improve quality of neurologic care

Clinical quality data registries are increasingly popular tools used by providers to improve the quality of clinical care and satisfy growing numbers of regulatory and reporting requirements. Specialty societies use registries to provide value to their members and guide improvements in care at the population level. In this article, we outline the rationale, structure, function, and challenges related to the American Academy of Neurology's development of its own clinical quality data registry: the Axon Registry.

Reducing costs while enhancing quality of care in MS

The rapid escalation in prices of disease-modifying therapies (DMTs) for multiple sclerosis (MS) over the past decade has resulted in a dramatic overall increase in the costs of MS-related care. In this article, we outline various approaches whereby neurologists can contribute to responsible cost containment while maintaining, and even enhancing, the quality of MS care. The premise of the article is that clinicians are uniquely positioned to introduce innovative management strategies that are both medically sound and cost-efficient. We describe our "top 5" recommendations, including strategies for customizing relapse treatment; developing alternative dosing schedules for Food and Drug Administration-approved MS DMTs; using off-label therapies for relapse suppression; and limiting the use of DMTs to those who clearly fulfill diagnostic criteria, and who might benefit from continued use over time. These suggestions are well-grounded in the literature and our personal experience, but are not always supported with rigorous Class I evidence as yet. We advocate for neurologists to take a greater role in shaping clinical research agendas and helping to establish cost-effective approaches on a firm empiric basis.
