The Digital Neurologic Examination

Digital Health for Oncological Care

ABSTRACT

Digital health tools extend well beyond telemedicine, holding great potential to advance oncological care. We survey digital health and provide recommendations across the health continuum, tailoring them to oncology, including prevention, detection and diagnosis, and treatment and monitoring. Within the prevention realm, we review wellness technologies, cancer screening, mental health solutions, and digital biomarkers. For detection and diagnosis, we describe existing and emerging solutions for remote patient monitoring and various means to capture digital biomarkers, the "digital exam," and "digital outcomes." Treatment and monitoring solutions include telemedicine, chatbots, and digital therapeutics, which are also explored. We also discuss a host of technology enablers that are required for successful implementation and sustainment of digital health-enabled care. Our recommendations pertain to health care systems as well as companies that work with these systems or provide care to patients directly.

Feasibility and Acceptability of a Multidisciplinary Academic Telemedicine System for Memory Care in Response to COVID-19

Background and Objectives

In response to the restrictions imposed by the COVID-19 pandemic, the University of California San Francisco Memory and Aging Center (UCSF MAC) has deployed a comprehensive telemedicine model for the diagnosis and management of Alzheimer disease and related dementias. This review summarizes a large academic behavioral neurology clinic's experience transitioning to telemedicine services, including the impact on clinic care indicators, access metrics, and provider's experience. We compared these outcomes from 3 years before COVID-19 to 12 months after the transition to video teleconferencing (VTC) encounters.

Methods

Patient demographics and appointment data (dates, visit types, and departments) were extracted from our institution's electronic health record database from January 1, 2017, to May 1, 2021. We present data as descriptive statistics and comparisons using Wilcoxon rank-sum tests and Fisher exact tests. The results of anonymous surveys conducted among the clinic's providers are reported as descriptive findings.

Results

After the implementation of telemedicine services, the proportion of clinic encounters completed via VTC increased from 1.9% to 86.4%. There was a statistically significant decline in both the percentage of scheduled appointments that were canceled (32.9% vs 27.9%; p < 0.01) and total cancelations per month (mean 240.3 vs 179.4/mo; p < 0.01). There was an increase in the percentage of completed scheduled appointments (60.2% vs 64.8%; p < 0.01) and an increase in the average estimated commuting distance patients would need to drive for follow-up appointments (mean 49.8 vs 54.7 miles; p < 0.01). The transition to telemedicine services did not significantly affect the clinic's patient population as measured by age, gender, estimated income, area deprivation index, or self-reported racial/ethnic identity. The results of the provider survey revealed that physicians reported a more positive experience relative to neuropsychologists. Both types of providers reported telemedicine services as a reasonable equivalent and acceptable alternative to in-person evaluations with notable caveats.

Discussion

UCSF MAC's comprehensive integration of telemedicine services maintained critical ambulatory care to patients living with dementia during the COVID-19 pandemic. The recognized benefits of our care model suggest dementia telemedicine may be used as a feasible and equivalent alternative to in-person ambulatory care in the after COVID-19 era.

Consequences of inequity in the neurosurgical workforce: Lessons from traumatic brain injury

Women and minorities leave or fail to advance in the neurosurgical workforce more frequently than white men at all levels from residency to academia. The consequences of this inequity are most profound in fields such as traumatic brain injury (TBI), which lacks objective measures. We evaluated published articles on TBI clinical research and found that TBI primary investigators or corresponding authors were 86·5% White and 59·5% male. First authors from the resulting publications were 92.6% white. Most study participants were male (68%). 64·4% of NIH-funded TBI clinical trials did not report or recruit any black subjects and this number was even higher for other races and the Hispanic ethnicity. We propose several measures for mitigation of the consequences of the inequitable workforce in traumatic brain injury that could potentially contribute to more equitable outcomes. The most immediately feasible of these is validation and establishment of objective measures for triage and prognostication that are less susceptible to bias than current protocols. We call for incorporation of gender and race neutral metrics for TBI evaluation to standardize classification of injury. We offer insights into how socioeconomic factors contribute to increased death rates from women and minority groups. We propose the need to study how these disparities are caused by unfair health insurance reimbursement practices. Surgical and clinical research inequities have dire consequences, and until those inequities can be corrected, mitigation of those consequences requires system wide change.

Aligning mission to digital health strategy in academic medical centers

The strategies of academic medical centers arise from core values and missions that aim to provide unmatched clinical care, patient experience, research, education, and training. These missions drive nearly all activities. They should also drive digital health activities - and particularly now given the rapid adoption of digital health, marking one of the great transformations of healthcare; increasing pressures on health systems to provide more cost-effective care; the pandemic-accelerated funding and rise of well-funded new entrants and technology giants that provide more convenient forms of care; and a more favorable regulatory and reimbursement landscape to incorporate digital health approaches. As academic medical centers emerge from a pandemic-related reactionary digital health posture, where pressures to adopt more digital health technologies mount, a broad digital health realignment that leverages the strengths of such centers is required to accomplish their missions.

Telehealth for Comprehensive Care of Acute Neurologic Disorders

A teleneurology hospitalist model aims to address the demand for high-quality neurologic acute care and the shortage of neurologists. Here, we review concepts and models of teleneurology services to address access and care gaps in neurology beyond telestroke models. The goal of these emergent teleservices is to empower community hospitals to deliver the highest quality care, while also reducing unnecessary patient transfers to tertiary care hospitals. We highlight the clinical models, patient populations, and innovative approaches of different tele-neurohospitalist services. This includes challenges related to clinical limitations, legal issues, and reimbursement. We highlight specific areas of research that can further clarify and refine the appropriate use, cost-effectiveness, and clinical outcomes of these telemedicine-based care models.

Training of neurologists for the 21st century: cultural and professional skills

Training of neurologists for the near future is a challenge due to the likely advances in neuroscientific methods, which will change much of our knowledge on diagnosis and treatment of neurological diseases.

OBJECTIVE

to comment on what may be more likely to be a constant in the very near future and to recommend how to prepare the neurologist for the 21st century.

METHODS

through a critical review of recent articles on the teaching of Neurology, to present a personal view on the subject.

RESULTS

Diagnostic methods and therapeutic resources in Neurology will be greatly improved, but the central core of teaching young neurologists will continue to be the clinical/anatomical correlation. The neurologist must be prepared to be the primary physician in the care of patients with neurological disorders, although the roles of consultant and clinical neuroscientist must also be considered. In addition to technical knowledge, the neurologist must be prepared to discuss not only distressing issues related to the specialty, such as the risks of genetic diseases for family members of their patients, the inexorable progression of some diseases and the need for palliative care, but also problems not directly related to Neurology that cause anxiety and depression in the patient or that are the main reason for the initial consultation.

CONCLUSION

neurology will be an even more important area of medicine and the neurologist must be well prepared to be the primary doctor to diagnose, treat and follow the patient with neurological disorders. In addition to technical knowledge, training in doctor-patient relations should be highlighted.

A Digital Health Service for Elderly People with Balance Disorders and Risk of Falling: A Design Science Approach

In this study, a design science research methodology was used aiming at designing, implementing and evaluating a digital health service to complement the provision of healthcare for elderly people with balance disorders and risk of falling. An explanatory sequential mixed methods study allowed to identify and explore the dissatisfaction with electronic medical records and the opportunity for using digital health solutions. The suggested recommendations helped to elaborate and develop “BALANCE”, a digital service implemented on the METHIS platform, which was recently validated for remote monitoring of chronic patients in primary healthcare. “BALANCE” provides clinical and interactive data, questionnaire pre and post-balance rehabilitation, tutorial videos with balance exercises and patient-recorded videos of the exercises. This digital service was demonstrated, including five elderly patients with clinical recommendations for balance rehabilitation at home. Finally, the authors conducted two focus groups with the participants and their caregivers as well as with physicians. The focus groups aimed at exploring their satisfaction level, needs of adjustment in the “BALANCE” service and strategies for applicability. The digital healthcare service evaluation revealed a significant potential for clinical applicability of this digital solution for elderly people with balance disorders and risk of falling.

The digital Cullen chart: a red colour perimetry aid for visual field examination

BACKGROUND

30 years ago, a paper chart was developed in Edinburgh by Cullen et al. and validated as a swift, supplementary method for perimetric evaluation of visual fields. We have re-developed this concept in digital form (on smartphone screen) and assessed its sensitivity and specificity in detecting visual field loss, by comparison with formal machine-based perimetry.

METHODS

Patients with sellar and parasellar tumours, being managed in a single neurosurgical centre, underwent formal visual field perimetry as part of standard care. They also underwent assessment using the smartphone-based Cullen chart. 37 eye testing episodes were assessed, incorporating pre- and post-treatment assessments for a range of potentially compressive pathologies (non-secretory and secretory pituitary adenoma, craniopharyngioma, and parasellar meningioma). The smartphone-based Cullen chart was compared with formal machine-based perimetry for concordance in detecting visual field loss.

RESULTS

The digital Cullen chart had a sensitivity of 75% and specificity of 98% compared with machine-based perimeters. The positive predictive value was 93% and the negative predictive value was 92%.

CONCLUSIONS

For the visual field assessment of patients with sellar/parasellar tumours, this simple and swift smartphone-based chart shows good concordance with machine-based perimeters. With amendments to the user interface, there may be potential for telemetric patient-led visual field monitoring.
