Assessing Deaf patients in the neurology clinic.

There are over 87 000 Deaf people in the UK with British Sign Language (BSL) as their first language.1 Few healthcare professionals receive training in Deaf awareness or in BSL, and missed diagnoses and inadequate treatment of Deaf patients are estimated to cost the National Health Service £30 million per year.2 Neurologists are likely to encounter Deaf BSL users in their practice, but without prior experience may find consultations challenging, especially within the time constraints and pressure of a standard clinic. In this article, we provide guidance on consulting with Deaf people in a neurology clinic, drawing on experience from our cognitive clinic for Deaf BSL users where effective communication is essential.

The relationship of study and authorship characteristics on trial sponsorship and self-reported conflicts of interest among neuro-oncology clinical trials.

PROPOSE: To examine the association between trial sponsorship sources, self-reported conflicts of interest (COI), and study and author characteristics in central nervous system (CNS) oncology clinical trials (CT). METHODS: MEDLINE search was performed for original CT on "Central Nervous System Neoplasms"[Mesh]. The investigators assessed for relationships between funding source (industry, academic or cooperative, none, not described), COI (presented, none, or not reported), CT, and author characteristics. RESULTS: From 2010 to 2015, 319 CT were considered eligible. The majority of the studies involved primary gliomas (55.2%) and were Phase II CT (59.2%). Drug therapy was investigated in 83.0% of the CT. The remaining studies investigated surgery or radiotherapy. A minority of papers were published in journals with impact factor (IF) higher than > 10 (16%) or in regions other than North America and Europe (20.4%). Overall, 83.1% of studies disclosed funding sources: 32.6% from industry alone, 33.9% from an academic or cooperative group, and 10.7% from a mixed funding model. COI data was reported by 85.9% of trials, of which 56.2% reported no COI and 43.8% reported a related COI. Significant predictors for sponsorship (industry and/or academia) on univariate analysis were study design, type of intervention, journal impact factor, study conclusion, transparency of COI and presence of COI. On multivariate analysis, type of intervention, (P < 0.001), journal impact factor (IF) (P = 0.003), presence of COI (P < 0.001) and study conclusion (P = 0.003) remained significant predictors of sponsorship. For predicting COI, significant variables on univariate analysis were disease type, type of intervention, journal IF, funding source, and intervention arm being related to sponsor. On multivariate analysis, disease type (P = 0.003), journal IF (P < 0.001), type of intervention (P = 0.001), and funding source (P = 0.008) remained significant. CONCLUSIONS: The majority of CNS CT reported some external funding sources and non-related COI. We identified that drug trials, higher IF, presence of COI, and a neutral or negative study conclusion are associated with external funding. Likewise drug trials, higher IF, and glioma trials are associated with presence of COI.

Funding source, conflict of interest and positive conclusions in neuro-oncology clinical trials.

We aimed to test any association between authors' conclusions and self-reported COI or funding sources in central nervous system (CNS) studies. A review was performed for CNS malignancy clinical trials published in the last 5 years. Two investigators independently classified study conclusions according to authors' endorsement of the experimental therapy. Statistical models were used to test for associations between positive conclusions and trials characteristics. From February 2010 to February 2015, 1256 articles were retrieved; 319 were considered eligible trials. Positive conclusions were reported in 56.8% of trials with industry-only, 55.6% with academia-only, 44.1% with academia and industry, 77.8% with none, and 76.4% with not described funding source (p = 0.011). Positive conclusions were reported in 60.4% of trials with unrelated COI, 60% with related COI, and 60% with no COI reported (p = 0.997). Factors that were significantly associated with the presence of positive conclusion included trials design (phase 1) [OR 11.64 (95 CI 4.66-29.09), p < 0.001], geographic location (outside North America or Europe) [OR 1.96 (95 CI 1.05-3.79), P = 0.025], primary outcomes (non-overall or progression free survival) [OR 3.74 (95 CI 2.27-6.18), p < 0.001], and failure to disclose funding source [OR 2.45 (95 CI 1.22-5.22), p = 0.011]. In a multivariable regression model, all these factors remained significantly associated with trial's positive conclusion. Funding source and self-reported COI did not appear to influence the CNS trials conclusion. Funding source information and COI disclosure were under-reported in 14.1 and 17.2% of the CNS trials. Continued efforts are needed to increase rates of both COI and funding source reporting.

The Global Neurological Burden of Tuberculosis.

Central nervous system (CNS) involvement of tuberculosis (TB) is the most severe manifestation of TB and accounts for approximately 5 to 10% of all extrapulmonary TB (EPTB) cases and approximately 1% of all TB cases. TB meningitis (TBM) is the most common form of CNS TB, though other forms occur, often in conjunction with TBM, including intracranial tuberculomas, tuberculous brain abscesses, and spinal tubercular arachnoiditis. CNS TB often presents with nonspecific clinical features that mimic symptoms of other neurological conditions, often making diagnosis difficult. Defining neuroimaging characteristics of TBM include thick basal meningeal enhancement, hydrocephalus, and parenchymal infarctions most commonly involving the basal ganglia and internal capsule. Traditional cerebrospinal fluid sample analysis frequently requires lengthy times-to-result and have low sensitivity. Given the pitfalls of conventional CNS TB diagnostic methods, various molecular-based methods, including immunoassays and polymerase chain reaction (PCR)-based assays have emerged as alternative diagnostic tools due to their rapidity, sensitivity, and specificity. Expert panels on TBM have recently emphasized the need for standard research procedures with updated case definitions and standardized study methods, which will hopefully pave the way for more robust multicenter international studies. In this article, we review the epidemiology, diagnosis, molecular factors associated with disease presentation and outcome, and treatment of CNS TB.

Costs, outcome and cost-effectiveness of neurocritical care: a multi-center observational study.

BACKGROUND: Neurocritical illness is a growing healthcare problem with profound socioeconomic effects. We assessed differences in healthcare costs and long-term outcome for different forms of neurocritical illnesses treated in the intensive care unit (ICU). METHODS: We used the prospective Finnish Intensive Care Consortium database to identify all adult patients treated for traumatic brain injury (TBI), intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH) and acute ischemic stroke (AIS) at university hospital ICUs in Finland during 2003-2013. Outcome variables were one-year mortality and permanent disability. Total healthcare costs included the index university hospital costs, rehabilitation hospital costs and social security costs up to one year. All costs were converted to euros based on the 2013 currency rate. RESULTS: In total 7044 patients were included (44% with TBI, 13% with ICH, 27% with SAH, 16% with AIS). In comparison to TBI, ICH was associated with the highest risk of death and permanent disability (OR 2.6, 95% CI 2.1-3.2 and OR 1.7, 95% CI 1.4-2.1), followed by AIS (OR 1.9, 95% CI 1.5-2.3 and OR 1.5, 95% CI 1.3-1.8) and SAH (OR 1.8, 95% CI 1.5-2.1 and OR 0.8, 95% CI 0.6-0.9), after adjusting for severity of illness. SAH was associated with the highest mean total costs (€51,906) followed by ICH (€47,661), TBI (€43,916) and AIS (€39,222). Cost per independent survivor was lower for TBI (€58,497) and SAH (€96,369) compared to AIS (€104,374) and ICH (€178,071). CONCLUSION: Neurocritical illnesses are costly and resource-demanding diseases associated with poor outcomes. Intensive care of patients with TBI or SAH more commonly result in independent survivors and is associated with lower total treatments costs compared to ICH and AIS.

Diagnosing and treating dementia in German primary and specialized care between 2011 and 2015
.

BACKGROUND: Whilst there was no upturn in detection rate of persons with dementia (PwD) in German general practitioner (GP) practices before 2012, dementia diagnoses markedly increased in 2013 and 2014. OBJECTIVE: (1) Verify the increase of dementia diagnoses in GP practices and neurologist/psychiatrist (NP) practices; (2) examine the subsequent prescription of antidementia drugs. MATERIALS AND METHODS: We performed a retrospective, longitudinal analysis of 874 GP and 141 NP practices collecting clinical data about 220,213 patients who received a dementia diagnosis (ICD-10: G30, F01, F03) between 2011 and 2015. RESULTS: In GP practices, documented dementia diagnoses increased by 73% between 2012 and 2014 (mean 6.4 - 11.1 PwD/practice) and decreased by 26% in 2015 (8.3 PwD/practice). This trend was mostly due to the subgroup of nonspecific (+63%) and vascular dementia (+170%). The upturn has been accompanied by a downturn of the proportion of PwD receiving antidementia drugs (2012: 13.9% vs. 2014: 7.8%). Neither of these trends was found in NP practices. CONCLUSION: The upturn parallels the introduction of monetary incentives for both patients and GPs. It should be examined if these monetary incentives will also lead to an improvement in treatment and care of PwD in the long run.

A Profile of Neuro-Ophthalmic Practice Around the World.

BACKGROUND: To compare contrast neuro-ophthalmic practice in various countries, an 18-question survey was sent to the international North American Neuro-Ophthalmology Society (NANOS) members in the spring of 2016. METHODS: At least 1 NANOS member was contacted for each non-US nation in the NANOS membership roster. If there were multiple NANOS members from 1 country, multiple were contacted. If responses were received from more than 1 person from a single country, the first response received was used as the source data. The survey (in English) was emailed to 47 NANOS members from 31 countries. Twenty responses were received representing members from 15 nations. RESULTS: In all 15 nations, at least half of the neuro-ophthalmologists were trained as ophthalmologists. In 60% of nations, at least half of the neuro-ophthalmologists were trained internally, whereas in 33% of countries, at least half were trained in the United States. The number of physicians who practiced a significant amount of neuro-ophthalmology ranged from low (0.08/million, India) to high (3.10/million, Israel). Countries having the highest percentage of neuro-ophthalmologists exclusively practicing neuro-ophthalmology also were those with better patient access to neuro-ophthalmic care. Requirement of approval to see a neuro-ophthalmologist or for imaging studies requested by neuro-ophthalmologists was not typical. In most nations, academic neuro-ophthalmologists were paid a straight salary. In no nation were neuro-ophthalmologists paid more than another ophthalmic subspecialty. CONCLUSIONS: Individual national health care system designs and compensation models have had a profound influence on the rewards and challenges that face neuro-ophthalmologists. There seems to have been a connection between recognition of the discipline, financial rewards of neuro-ophthalmic practice, conditions that permit full-time neuro-ophthalmic practice, and patient access to care. A higher percentage of gross national product for health care did not seem to insure an adequate supply of neuro-ophthalmologists.

Impact of Stroke Call on the Stroke Neurology Workforce in the United States: Possible Challenges and Opportunities.

BACKGROUND: The Stroke & Vascular Neurology Section of the American Academy of Neurology was charged to identify challenges to the recruitment and retention of stroke neurologists and to make recommendations to address any identified problems. The Section initiated this effort by determining the impact of stroke on-call requirements as a barrier to the recruitment and retention of vascular neurologists. METHODS: This is a cross-sectional survey of a sample of US Neurologists providing acute stroke care. RESULTS: Of the 900 neurologists who were sent surveys, 313 (35%) responded. Of respondents from institutions providing stroke coverage, 71% indicated that general neurologists and 45% indicated that vascular neurologists provided that service. Of those taking stroke call, 36% agreed with the statement, "I spent too much time on stroke call," a perception that was less common among those who took less than 12-hour shifts (P < .0001); 21% who participated in stroke call were dissatisfied with their current job. Forty-six percent indicated that their stroke call duties contributed to their personal feeling of "burnout." CONCLUSIONS: Although the reasons are likely multifactorial, our survey of neurologists providing stroke care suggests that over-burdensome on-call responsibilities may be contributing to the vascular neurology workforce burnout and could be affecting recruitment and retention of vascular neurologists. Strategies to reduce the lifestyle impact of stroke call may help address this problem.

Prescription Patterns and the Cost of Migraine Treatments in German General and Neurological Practices.

OBJECTIVES: The aim of this study was to analyze prescription patterns and the cost of migraine treatments in general practices (GPs) and neurological practices (NPs) in Germany. METHODS: This study included 43,149 patients treated in GPs and 13,674 patients treated in NPs who were diagnosed with migraine in 2015. Ten different families of migraine therapy were included in the analysis: triptans, analgesics, anti-emetics, beta-blockers, antivertigo products, gastroprokinetics, anti-epileptics, calcium channel blockers, tricyclic antidepressants, and other medications (all other classes used in the treatment of migraine including homeopathic medications). The share of migraine therapies and their costs were estimated for GPs and NPs. RESULTS: The mean age was 44.4 years in GPs and 44.1 years in NPs. Triptans and analgesics were the 2 most commonly prescribed families of drugs in all patients and in the 9 specific subgroups. Interestingly, triptans were more commonly prescribed in NPs than in GPs (30.9% to 55.0% vs. 30.0% to 44.7%), whereas analgesics were less frequently given in NPs than in GPs (11.5% to 17.2% vs. 35.3% to 42.4%). Finally, the share of patients who received no therapy was higher in NPs than in GPs (33.9% to 58.4% vs. 27.5% to 37.9%). The annual cost per patient was €66.04 in GPs and €94.71 in NPs. Finally, the annual cost per patient increased with age and was higher in women and in individuals with private health insurance coverage than in men and individuals with public health insurance coverage. CONCLUSION: Triptans and analgesics were the 2 most commonly prescribed drugs for the treatment of migraine. Furthermore, approximately 30% to 40% of patients did not receive any therapy. Finally, the annual cost per patient was higher in NPs than in GPs.

Delivering neurocritical care in resource-challenged environments.

PURPOSE OF REVIEW: Resource-challenged environments of low and middle-income countries face a significant burden of neurocritical illness. This review attempts to elaborate on the multiple barriers to delivering neurocritical care in these settings and the possible solutions to overcome such barriers. RECENT FINDINGS: Epidemiology of neurocritical illness appears to have changed over time in low and middle-income countries. In addition to neuro-infection, noncommunicable neurological illnesses like stroke, traumatic brain injury, and traumatic spinal cord injury pose a significant neurocritical burden in resource-limited settings. Many barriers that exist hinder effective delivery of neurocritical care in resource-challenged environments. Very little information exists about the neurocritical care capacity. Research and publications are few. Intensive care unit beds and trained personnel are significantly lacking. Awareness about the risk factors of preventable conditions, including stroke, is lacking. Prehospital care and trauma systems are poorly developed. There should be attempts to leverage neurocritical care in these settings with focus on promoting research, local training, capacity building, preventive measures like vaccination, raising awareness, and developing prehospital care. SUMMARY: Considering the disease burden and potentials to improve outcome, attempts should be made to develop neurocritical care in resource-challenged environments.

Standard of Care for Neuropsychological Monitoring in Pediatric Neuro-Oncology: Lessons From the Children's Oncology Group (COG).

As the mortality of pediatric cancers has decreased, focus on neuropsychological morbidities of treatment sequelae have increased. Neuropsychological evaluations are essential diagnostic tools that assess cognitive functioning and neurobiological integrity. These tests provide vital information to support ongoing medical care, documenting cognitive morbidity and response to interventions. We frame standards for neuropsychological monitoring of pediatric patients with CNS malignancy or who received cancer-directed therapies involving the CNS and discuss billing for these services in the United States in the context of clinical research. We describe a cost-effective, efficient model of neuropsychological monitoring that may increases access to neuropsychological care.

Telemedicine Interest for Routine Follow-Up Care Among Neurology Patients in Arkansas.

BACKGROUND: Teleneurology in Arkansas has been used primarily for management of acute stroke with a state-funded hub-and-spoke model allowing physicians at rural hospitals to access vascular neurologists in time to facilitate tissue plasminogen activator administration. Routine neurologic care has been provided only in small pilot studies. We wished to determine patient interest in participating in teleneurology for routine follow-up visits as well as demographic and medical factors associated with interest. MATERIALS AND METHODS: New and established patients of the Neurology Outpatient Clinic at the University of Arkansas for Medical Sciences (UAMS) were surveyed between March 2011 and December 2012 to assess their interest in participating in teleneurology as well as potential factors associated with their interest. RESULTS: Of 1,441 respondents, 52.4% were interested in telemedicine. Of those interested versus uninterested in telemedicine, respectively, 68.9% versus 36.32% traveled more than 1 h to the clinic, 64.7% versus 35.3% had difficulty secondary to neurological conditions, 22.6% versus 6.8% had missed medical appointments due to travel problems, and 43.1% versus 9.4% had travel-imposed financial hardship. CONCLUSIONS: Telemedicine interest for routine follow-up visits was strong among patients at the UAMS Neurology Outpatient Clinic. Factors positively associated with interest included long travel distances, travel expenses, and transportation difficulties. These results suggest that implementing a telemedicine program for follow-up visits would be acceptable to neurology patients for routine ongoing care.

Cost-effectiveness of transfers to centers with neurological intensive care units after intracerebral hemorrhage.

BACKGROUND AND PURPOSE: Our aim was to estimate the cost-effectiveness of transferring patients with intracerebral hemorrhage from centers without specialized neurological intensive care units (neuro-ICUs) to centers with neuro-ICUs. METHODS: Decision analytic models were developed for the lifetime horizons. Model inputs were derived from the best available data, informed by a variety of previous cost-effectiveness models of stroke. The effect of neuro-ICU care on functional outcomes was modeled in 3 scenarios. A favorable outcomes scenario was modeled based on the best observational data and compared with moderately favorable and least-favorable outcomes scenarios. Health benefits were measured in quality-adjusted life years (QALYs), and costs were estimated from a societal perspective. Costs were combined with QALYs gained to generate incremental cost-effectiveness ratios. One-way sensitivity analysis and Monte Carlo simulations were performed to test robustness of the model assumptions. RESULTS: Transferring patients to centers with neuro-ICUs yielded an incremental cost-effectiveness ratio for the lifetime horizon of $47,431 per QALY, $91,674 per QALY, and $380,358 per QALY for favorable, moderately favorable, and least-favorable scenarios, respectively. Models were robust at a willingness-to-pay threshold of $100,000 per QALY, with 95.5%, 75.0%, and 2.1% of simulations below the threshold for favorable, moderately favorable, and least-favorable scenarios, respectively. CONCLUSIONS: Transferring patients with intracerebral hemorrhage to centers with specialized neuro-ICUs is cost-effective if observational estimates of the neuro-ICU-based functional outcome distribution are accurate. If future work confirms these functional outcome distributions, then a strong societal rationale exists to build systems of care designed to transfer intracerebral hemorrhage patients to specialized neuro-ICUs.

The Operational and Economic Impact of a Neurovascular Unit in an Acute Care Academic Hospital.

BACKGROUND: There is strong evidence that clinical outcomes are improved for stroke patients admitted to specialized Stroke Units. The Toronto Western Hospital (TWH) created a Neurovascular Unit (NVU) using resources from General Internal Medicine, Neurology, and Neurosurgery for patients with stroke and acute neurovascular conditions. Under resource-constrained conditions, the operational and economic impacts of the Neurovascular Unit were unknown. METHODS: Retrospective patient-level data was studied from two years prior and one year post NVU implementation. Descriptive statistical analysis and non-parametric testing were conducted on the acute length of stay (LOS), alternate level of care LOS, total cost per bed-day and per visit, and patient flow within each medical service and hospital wide. RESULTS: The median acute LOS per hospitalization for NVU-eligible patients decreased significantly (p=0.001). For Neurology patients, mean acute LOS decreased from 9.1 days pre-Neurovascular Unit to 7.6 days post and median acute LOS decreased from 6 to 5 days (p=0.002); however, mean alternate level of care LOS per visit more than doubled (from 1.6 to 4.1 days, p=0.001). For the Neurology service, the mean cost per visit decreased by $945, representing a 5% reduction (p=0.042) and the mean cost per bed-day decreased by $233, or 12.5% (p=0.026). Hospital wide, a saving of over C$450 000 was achieved. CONCLUSIONS: During the first year of operation, the NVU at TWH achieved decreased acute LOS per visit and lowered the total hospitalization cost per year for NVU-eligible patients. Addressing the issue of increased alternate level of care LOS could result in additional efficiencies.

[Promotion of physical activity for secondary prevention in patients with chronic diseases: the situation in the Grand-Duchy of Luxembourg]. / Promotion de l'activité physique comme moyen de prévention secondaire chez des patients atteints de maladies chroniques: état des lieux au Grand-Duché de Luxembourg.

The regular practice of physical activities has health benefits in healthy subjects (primary prevention) and in patients with non-communicable diseases (secondary prevention). This study aimed to perform a stocktaking of the physical activities programs for patients or individuals at risk in the Grand-Duchy of Luxembourg. The organizations offering therapeutic physical activities (TPA) have been investigated. Eleven groups offering TPA adapted to different non-communicable diseases were characterized by their costs, instructors, participants and potential participants. These groups were divided into five main categories: cardiology, neurology, obesity, oncology, and orthopedics. During on-site meetings, 41 professionals, 192 participants and 34 potential participants have been interviewed during the period September 2013 to April 2014. The results show that about 40 hours of TPA, 17 hours of which in cardiology, are currently proposed every week, except during school holidays. The main TPA are gymnastics, aerobics, swimming, Nordic walking, cycling, and resistance training. The national coverage is quite low, especially for obesity, neurology and orthopedics. The costs is mainly related to the human resources, the gym being often borrowed but rarely available during school holidays. Between 200 and 400 individuals participate in the TPA. The average number of participants per hour is 8.9 (± 5.1), which represents only 50% of the maximal capacity estimated by the instructors (18.0 ± 8.2 participants per hour). The recruitment process is different according to the groups but the medical doctors and the physiotherapists are mainly involved in this process. However, the majority of the potential participants were not aware of the existence of the groups. The existence of these groups is a positive point, since it contributes to compensate for the current lack of concrete action of the public and private authorities. However, the current TPA offer is clearly insufficient. The groups are frail, on the one hand because their future relies exclusively upon the idealism of a few key actors, and on the other hand because the participation rate is low. This low rate is related to a lack of information and to organizational constraints. However, the public health action initiated by these groups should be perpetuated and strengthened with a better structuration and professionalization. Finally, the increase of the number of participants remains the main objective.
