Cognitive Assessment of Patients With Alzheimer's Disease by Telemedicine: Pilot Study

Needs for Successful Engagement in Telemedicine Among Rural Older US Veterans and Their Caregivers: Qualitative Study

BACKGROUND

Telemedicine is an important option for rural older adults who often must travel far distances to clinics or forgo essential care. In 2014, the Geriatric Research, Education, and Clinical Centers (GRECC) of the US Veterans Health Administration (VA) established a national telemedicine network called GRECC Connect. This network increased access to geriatric specialty care for the 1.4 million rural VA-enrolled veterans aged 65 years or older. The use of telemedicine skyrocketed during the COVID-19 pandemic, which disproportionately impacted older adults, exacerbating disparities in specialty care access as overburdened systems shut down in-person services. This surge presented a unique opportunity to study the supports necessary for those who would forgo telemedicine if in-person care were available.

OBJECTIVE

In spring 2021, we interviewed veterans and their informal caregivers to (1) elicit their experiences attempting to prepare for a video visit with a GRECC Connect geriatric specialist and (2) explore facilitators and barriers to successful engagement in a telemedicine visit.

METHODS

We conducted a cross-sectional qualitative evaluation with patients and their caregivers who agreed to participate in at least 1 GRECC Connect telemedicine visit in the previous 3 months. A total of 30 participants from 6 geographically diverse GRECC Connect hub sites agreed to participate. Semistructured interviews were conducted through telephone or the VA's videoconference platform for home telemedicine visits (VA Video Connect) per participant preference. We observed challenges and, when needed, provided real-time technical support to facilitate VA Video Connect use for interviews. All interviews were recorded with permission and professionally transcribed. A team of 5 researchers experienced in qualitative research analyzed interview transcripts using rapid qualitative analysis.

RESULTS

From 30 participant interviews, we identified the following 4 categories of supports participants described regarding successful engagement in telemedicine, as defined by visit completion, satisfaction, and willingness to engage in telemedicine in the future: (1) caregiver presence to facilitate technology setup and communication; (2) flexibility in visit modality (eg, video from home or a clinic or telephone); (3) technology support (eg, determining device compatibility or providing instruction and on-demand assistance); and (4) assurance of comfort with web-based communication, including orientation to features like closed captioning. Supports were needed at multiple points before the visit, and participants stressed the importance of eliciting the varying needs and preferences of each patient-caregiver dyad. Though many initially agreed to a telemedicine visit because of pandemic-related clinic closures, participants were satisfied with telemedicine and willing to use it for other types of health care visits.

CONCLUSIONS

To close gaps in telemedicine use among rural older adults, supports must be tailored to individuals, accounting for technology availability and comfort, as well as availability of and need for caregiver involvement. Comprehensive scaffolding of support starts well before the first telemedicine visit.

Tele-Neuropsychology: From Science to Policy to Practice

OBJECTIVE

The primary aim of this paper is to accelerate the number of randomized experimental studies of the reliability and validity in-home tele-neuropsychological testing (tele-np-t).

METHOD

We conducted a critical review of the tele-neuropsychology literature. We discuss this research in the context of the United States' public and private healthcare payer systems, including the Centers for Medicare & Medicaid Services (CMS) and Current Procedural Terminology (CPT) coding system's telehealth lists, and existing disparities in healthcare access.

RESULTS

The number of tele-np publications has been stagnant since the onset of the COVID-19 pandemic. There are less published experimental studies of tele-neuropsychology (tele-np), and particularly in-home tele-np-t, than other tele-np publications. There is strong foundational evidence of the acceptability, feasibility, and reliability of tele-np-t, but relatively few studies of the reliability and validity of in-home tele-np-t using randomization methodology.

CONCLUSIONS

More studies of the reliability and validity of in-home tele-np-t using randomization methodology are necessary to support inclusion of tele-np-t codes on the CMS and CPT telehealth lists, and subsequently, the integration and delivery of in-home tele-np-t services across providers and institutions. These actions are needed to maintain equitable reimbursement of in-home tele-np-t services and address the widespread disparities in healthcare access.

Telemedicine interventions for older adults: A systematic review

INTRODUCTION

Telemedicine may help improve older adults' access, health outcomes, and quality of life indicators. This review aims to provide current evidence on the effectiveness of telemedicine in the aged population.

METHOD

A systematic literature search was conducted in PubMed, Google Scholar, and Web of Science electronic databases between January 2015 and September 2021 using the keywords "telemedicine" or "telehealth" and "older people" or "geriatrics" or "elderly." The articles were classified under three headings according to the purposes: feasibility, diagnosis and management of chronic diseases, and patient satisfaction.

RESULTS

A total of 22 articles were included. Across most disciplines, evidence has shown that telemedicine is as effective as usual care, if not more so, in the feasibility, chronic disease management, and patient satisfaction of the elderly. However, a few studies reported challenges such as difficulty with technology, hearing problems, and the inability to perform hands-on examinations for physicians.

CONCLUSION

Findings from this review support the view that health care providers can use telemedicine to manage elderly individuals in conjunction with usual health care. However, future research is needed to eliminate barriers to increasing telemedicine use among older adults.

TelePriming sentence production in aphasia

Background

The application of videoconferencing to the assessment and treatment of aphasia has been rapidly increasing; however, there is a need to develop treatments targeting sentence production in persons with aphasia (PWA) that can be delivered through videoconferencing. Structural priming has received recent attention as a potential training method for PWA. We investigated the feasibility and efficacy of a collaborative structural priming task delivered via the internet, TelePriming, in facilitating sentence production in PWA and healthy adults.

Method

In Study 1, young adults (YA), older adults (OA), and PWA participated in a collaborative dialogue-like priming task through videoconferencing, taking turns with an interlocutor (experimenter) to describe transitive action pictures with the goal of finding matching pictures. We measured whether participants produced more passive sentences to describe their picture after hearing their interlocutor produce passive compared to active sentences (primes). In Study 2, we compared the data from the OA and PWA of Study 1 (TelePriming) to different groups of OA and PWA, who completed the same priming task in person.

Results

All three groups showed robust priming effects in Study 1, producing more passive sentences to describe target pictures after hearing the experimenter produce passive versus active sentences. In Study 2, when controlling for demographic information (age, education) and aphasia severity, TelePriming resulted in larger priming effects for OA and PWA, compared to the in-person priming task. Survey results revealed that both OA and PWA experienced increased comfort and satisfaction with using technology following the task.

Conclusion

Interactive message-structure alignment processes remain largely intact in PWA, and the positive effects of structural priming in a collaborative communicative task are not diminished by remote delivery. The findings demonstrate the feasibility and validity of TelePriming in OA and PWA, laying experimental groundwork for future use of TelePriming in the assessment and treatment of clinical populations with limited access to face-to-face sessions.

Video Teleconference Administration of the Addenbrooke's Cognitive Examination-III for the Assessment of Neuropsychological Status: An Experience in Indian Subjects with Cognitive Dysfunction

Objective

To determine the feasibility, reliability, and acceptability of video teleconference (VTC)-based neuropsychological assessment using Addenbrooke's cognitive examination-III (ACE-III).

Methods

This study was performed from January 2022 to April 2022, during the third wave of the COVID-19 pandemic in India. We administered ACE-III using video-teleconferencing and compared the scores to face-to-face (FTF) testing for the eligible participants. We also conducted a participant's satisfaction survey of VTC-administered ACE-III compared to FTF-administered ACE-III, using a 7-point Likert scale.

Results

We screened 37 participants and 24 (64.9%) successfully underwent ACE-III testing through VTC. We included 20 patients (mean age: 62.7 ± 10 years, mean education: 12.0 ± 4.6 years, 85% men) for final analysis, (who completed both VTC and FTF-administered ACE-III). Nine patients had major neurocognitive disorder (dementia), eight had mild neurocognitive disorder (MCI), and three had subjective cognitive decline (SCD). The two tests were administered at a median gap of 36 (18,74.5) days. The Intraclass correlation coefficients (ICC) of ACE-3 total scores (0.97) and the subdomain scores was high (>0.8). There was "very low" to "no" bias on the Bland-Altman plots, across all domains. The mean overall satisfaction score was 4.1, indicating that VTC is "as good as" FTF.

Conclusions

Results support the feasibility and acceptability of remote administration of ACE-III via VTC. There is a good agreement between the ACE-III scores across VTC and in-person conditions.

Teleneuropsychology: normative data for the assessment of memory in online settings

INTRODUCTION

The COVID-19 pandemic has forced significant changes in clinical practice. Psychologists and neuropsychologists had to modify their settings to assess patients' abilities, switching from an in-person modality to a remote setting by using video calling platforms. Consequently, this change brought about the need for new normative data tailored to remote settings.

AIM AND METHODS

The study aimed to develop normative data for the online assessment of neuropsychological memory tests and to compare it with the published norms obtained in standard settings. Two hundred and four healthy Italian volunteers performed three verbal memory tests through the Google Meet platform: the Digit Span (Backward and Forward), the Rey Auditory Verbal Learning, and the Verbal Paired Associated Learning Test.

RESULTS

This research provides specific norms that consider the influence of demographic characteristics. Their comparison with published norms shows a medium to high agreement between systems. The present study provides a reference for the clinical use of neuropsychological instruments to assess verbal memory in a remote setting and offers specific recommendations.

A Systematic Review of Physical Examination Components Adapted for Telemedicine

Introduction: The COVID-19 pandemic ushered in a rapid, transformative adoption of telemedicine to maintain patient access to care. As clinicians made the shift from in-person to virtual practice, they faced a paucity of established and reliable clinical examination standards for virtual care settings. In this systematic review, we summarize the accuracy and reliability of virtual assessments compared with traditional in-person examination tools. Methods: We searched PubMed, Embase, Web of Science, and CINAHL from inception through September 2019 and included additional studies from handsearching of reference lists. We included studies that compared synchronous video (except allowing for audio-only modality for cardiopulmonary exams) with in-person clinical assessments of patients in various settings. We excluded behavioral health and dermatological assessments. Two investigators abstracted data using a predefined protocol. Results: A total of 64 studies were included and categorized into 5 clinical domains: neurological (N = 41), HEENT (head, eyes, ears, nose, and throat; N = 5), cardiopulmonary (N = 5), musculoskeletal (N = 8), and assessment of critically ill patients (N = 5). The cognitive assessment within the neurological exam was by far the most studied (N = 19) with the Mini-Mental Status Exam found to be highly reliable in multiple settings. Most studies showed relatively good reliability of the virtual assessment, although sample sizes were often small (<50 participants). Conclusions: Overall, virtual assessments performed similarly to in-person exam components for diagnostic accuracy but had a wide range of interrater reliability. The high heterogeneity in population, setting, and outcomes reported across studies render it difficult to draw broad conclusions on the most effective exam components to adopt into clinical practice. Further work is needed to identify virtual exam components that improve diagnostic accuracy.

How Telemedicine Can Improve the Quality of Care for Patients with Alzheimer's Disease and Related Dementias? A Narrative Review

Background and Objectives: Dementia affects more than 55 million patients worldwide, with a significant societal, economic, and psychological impact. However, many patients with Alzheimer's disease (AD) and other related dementias have limited access to effective and individualized treatment. Care provision for dementia is often unequal, fragmented, and inefficient. The COVID-19 pandemic accelerated telemedicine use, which holds promising potential for addressing this important gap. In this narrative review, we aim to analyze and discuss how telemedicine can improve the quality of healthcare for AD and related dementias in a structured manner, based on the seven dimensions of healthcare quality defined by the World Health Organization (WHO), 2018: effectiveness, safety, people-centeredness, timeliness, equitability, integrated care, and efficiency. Materials and Methods: MEDLINE and Scopus databases were searched for peer-reviewed articles investigating the role of telemedicine in the quality of care for patients with dementia. A narrative synthesis was based on the seven WHO dimensions. Results: Most studies indicate that telemedicine is a valuable tool for AD and related dementias: it can improve effectiveness (better access to specialized care, accurate diagnosis, evidence-based treatment, avoidance of preventable hospitalizations), timeliness (reduction of waiting times and unnecessary transportation), patient-centeredness (personalized care for needs and values), safety (appropriate treatment, reduction of infection risk),integrated care (interdisciplinary approach through several dementia-related services), efficiency (mainly cost-effectiveness) and equitability (overcoming geographical barriers, cultural diversities). However, digital illiteracy, legal and organizational issues, as well as limited awareness, are significant potential barriers. Conclusions: Telemedicine may significantly improve all aspects of the quality of care for patients with dementia. However, future longitudinal studies with control groups including participants of a wide educational level spectrum will aid in our deeper understanding of the real impact of telemedicine in quality care for this population.

Effects of telehealth intervention for people with dementia and their carers: A systematic review and meta-analysis of randomized controlled studies

PURPOSE

Interventions delivered using telehealth modalities are becoming standard practice with patient populations around the world, partly because of innovation necessitated by the COVID-19 pandemic and partly due to improved infrastructure and comfort of providers, patients, and families, through technology. Though increasingly utilized, the effectiveness of telehealth interventions with families with dementia remains unclear. This gives rise to the need for investigation to develop telehealth interventions that are evidence based and not merely convenient tools. This current study is designed to systematically examine the impact and effectiveness of telehealth-delivered psychoeducational and behavioral interventions among persons with dementia and their caregivers.

DESIGN

The design combines systematic review and meta-analysis.

METHODS

A total of eight databases were electronically accessed and searched as of November 16, 2021. Experimental studies identifying the results of telehealth interventions for persons with dementia and associated caregivers published in English have been reviewed in this study. Standardized mean differences (SMD) offering 95% confidence intervals (CI) were developed to pool the effect size using a random effects model (in this case, Stata 16.0). The Revised Cochrane Risk-of-Bias Tool for Randomized Trials (RoB-2) was used to analyze the study's methodological soundness.

FINDINGS

Nineteen cases met the eligibility criteria (including 1379 persons with dementia and 1339 caregivers). Overall, telehealth interventions demonstrated effects in the expected directions on depression (SMD -0.63; 95% degree of confidence intervals (CI) -0.88 to -0.38, p < 0.001); and caregivers' perceived competency (SMD 0.27; 95% CI -0.05 to 0.50, p = 0.02). There were, however, no statistically significant effects observed on cognitive function or multiple aspects of quality of life for subjects.

CONCLUSIONS

Telehealth interventions appear to effect a reduction in depression among persons diagnosed with dementia while improving the perceived competency of caregivers.

CLINICAL RELEVANCE

The study's results could be used as evidence of the effectiveness of using telehealth for persons with dementia and their caregivers, including contextualizing where they are used (i.e., long-term care facilities, private homes, etc.), understanding the mechanisms in play (including intervention delivery and systems), and isolating and identifying mediating influences.

Remote neuropsychological evaluation of older adults

The use of technological means in the process of neuropsychological assessment has been proposed as a technique with promising results in the field of detection of neurocognitive disorders for community-dwelling older adults. Especially during the pandemic period due to COVID-19, telemedicine assumed to be vital in the field of early diagnosis of cognitive disorders and highlighted the clinical utility of remote methods of neuropsychological assessmentby video-conference. This descriptive study presents the development of a remote neuropsychological assessment protocol by selecting appropriate validated tests as part of a more comprehensive evaluation for older adults dwelling in the community. We recruited participants from the Athens Alzheimer's Association center in collaboration with the Hellenic Neuropsychological Society, in Athens, Greece, regarding the period between April 2020 and October 2021. 90 individuals, tested for the first time, were categorized into three groups according to their diagnosis which included: (a) Mild Cognitive Impairment (MCI), (b) Alzheimer's disease, (c) cognitively healthy older adults. The presented protocol outlines the main considerations of a framework about remote neuropsychological assessment, which can maximize the effectiveness of interventions and continuity regarding the care of older adults. The recommendations outlined in the presented protocol highlight strengths and limitations that should be taken into account in remote control procedures. Although the protocol was created in response to pandemic restrictions, tele-neuropsychology shows promise as a way to improve access opportunity to neurodiagnostic services for rural aging and underserved populations, which lack specialized healthcare services. Further application to different populations will add validity to the presented descriptive protocol.

RCT of the effectiveness of stepped-care sleep therapy in general practice: The RESTING study protocol

Cognitive behavioral therapy for insomnia (CBT-I) is an effective, non-pharmacological intervention, designated by the American College of Physicians as the first-line treatment of insomnia disorder. The current randomized controlled study uses a Hybrid-Type-1 design to compare the effectiveness and implementation potential of two approaches to delivering CBT-I in primary care. One approach offers therapy to all patients through an automated, digital CBT-I program (ONLINE-ONLY). The other is a triaged STEPPED-CARE approach that uses a simple Decision Checklist to start patients in either digital or therapist-led treatment; patients making insufficient progress with digital treatment at 2 months are switched to therapist-led treatment. We will randomize 240 individuals (age 50 or older) with insomnia disorder to ONLINE-ONLY or STEPPED-CARE arms. The primary outcomes are insomnia severity and hypnotic medication use, assessed at baseline and at months 2, 4, 6, 9, and 12 after randomization. We hypothesize that STEPPED-CARE will be superior to ONLINE-ONLY in reducing insomnia severity and hypnotic use. We also aim to validate the Decision Checklist and explore moderators of outcome. Additionally, guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework, we will use mixed methods to obtain data on the potential for future dissemination and implementation of each approach. This triaged stepped-care approach has the potential to improve sleep, reduce use of hypnotic medications, promote safety, offer convenient access to treatment, and support dissemination of CBT-I to a large number of patients currently facing barriers to accessing treatment. Clinical trial registration:NCT03532282.

Diagnostic test accuracy of remote, multidomain cognitive assessment (telephone and video call) for dementia

BACKGROUND

Remote cognitive assessments are increasingly needed to assist in the detection of cognitive disorders, but the diagnostic accuracy of telephone- and video-based cognitive screening remains unclear.

OBJECTIVES

To assess the test accuracy of any multidomain cognitive test delivered remotely for the diagnosis of any form of dementia. To assess for potential differences in cognitive test scoring when using a remote platform, and where a remote screener was compared to the equivalent face-to-face test.

SEARCH METHODS

We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group Specialized Register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, Web of Science, LILACS, and ClinicalTrials.gov (www.

CLINICALTRIALS

gov/) databases on 2 June 2021. We performed forward and backward searching of included citations.

SELECTION CRITERIA

We included cross-sectional studies, where a remote, multidomain assessment was administered alongside a clinical diagnosis of dementia or equivalent face-to-face test.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and extracted data; a third review author moderated disagreements. Our primary analysis was the accuracy of remote assessments against a clinical diagnosis of dementia. Where data were available, we reported test accuracy as sensitivity and specificity. We did not perform quantitative meta-analysis as there were too few studies at individual test level. For those studies comparing remote versus in-person use of an equivalent screening test, if data allowed, we described correlations, reliability, differences in scores and the proportion classified as having cognitive impairment for each test.

MAIN RESULTS

The review contains 31 studies (19 differing tests, 3075 participants), of which seven studies (six telephone, one video call, 756 participants) were relevant to our primary objective of describing test accuracy against a clinical diagnosis of dementia. All studies were at unclear or high risk of bias in at least one domain, but were low risk in applicability to the review question. Overall, sensitivity of remote tools varied with values between 26% and 100%, and specificity between 65% and 100%, with no clearly superior test. Across the 24 papers comparing equivalent remote and in-person tests (14 telephone, 10 video call), agreement between tests was good, but rarely perfect (correlation coefficient range: 0.48 to 0.98).

AUTHORS' CONCLUSIONS

Despite the common and increasing use of remote cognitive assessment, supporting evidence on test accuracy is limited. Available data do not allow us to suggest a preferred test. Remote testing is complex, and this is reflected in the heterogeneity seen in tests used, their application, and their analysis. More research is needed to describe accuracy of contemporary approaches to remote cognitive assessment. While data comparing remote and in-person use of a test were reassuring, thresholds and scoring rules derived from in-person testing may not be applicable when the equivalent test is adapted for remote use.

Tele-Assessments in Rural and Remote Schools – Perspectives of Support Teachers

Tele-assessments may enable specialist evaluation of students in schools and their progress following intervention. The aim of this project was to evaluate the feasibility of using videoconferencing technology to assess students with reading difficulties in the school setting and obtain the perspectives of teachers supporting the students during the assessment. Teachers ( n = 57) of 71 primary school age students participated in the study. Teachers provided feedback on the tele-assessment by completing questionnaires about students’ behaviours and the quality of the technology and assessment process. Randomly selected teachers ( n = 24) were invited to participate in a semi-structured interview to provide qualitative feedback. Tele-assessments were completed in 93.4% of the sample. Support teachers reported satisfaction with the audio and visual quality as well as the assessment process. The majority of students completed the tele-assessment with good compliance, engagement and attention. Feedback from support teachers also reflected the strengths of tele-assessments, such as better access to service, cost saving and convenience. Barriers to tele-assessments included technical difficulties, assessment limitations and equipment issues at schools. Tele-assessment is a feasible method of objectively measuring outcomes of students following an intervention. Tele-assessment at school is largely accepted by teachers who supported students in this study. Feedback obtained from this research may be used to offer guidance on undertaking tele-assessments with students in the school setting.

Cognitive assessment by telemedicine: reliability and agreement between face-to-face and remote videoconference-based cognitive tests in older adults attending a memory clinic

Background

The coronavirus disease 2019 (COVID-19) pandemic has spurred the rapid adoption of telemedicine. However, the reproducibility of face-to-face (F2F) versus remote videoconference-based cognitive testing remains to be established. We assessed the reliability and agreement between F2F and remote administrations of the Abbreviated Mental Test (AMT), modified version of the Chinese Mini-Mental State Examination (mCMMSE), and Chinese Frontal Assessment Battery (CFAB) in older adults attending a memory clinic.

Methods

The participants underwent F2F followed by remote videoconference-based assessment by the same assessor within 3 weeks. Reliability was evaluated using intraclass correlation coefficients (ICC; two-way mixed, absolute agreement), the mean difference between remote and F2F-based assessments using paired-sample t-tests, and agreement using Bland-Altman plots.

Results

Fifty-six subjects (mean age, 76±5.4 years; 74% mild; 19% moderate dementia) completed the AMT and mCMMSE, of which 30 completed the CFAB. Good reliability was noted based on the ICC values—AMT: ICC=0.80, 95% confidence interval [CI] 0.68–0.88; mCMMSE: ICC=0.80, 95% CI 0.63–0.88; CFAB: ICC=0.82, 95% CI 0.66–0.91. However, remote AMT and mCMMSE scores were higher compared to F2F—mean difference (i.e., remote minus F2F): AMT 0.3±1.1, p=0.03; mCMMSE 1.3±2.9, p=0.001. Significant differences were observed in the orientation and recall items of the mCMMSE and the similarities and conflicting instructions of CFAB. Bland–Altman plots indicated wide 95% limits of agreement (AMT -1.9 to 2.6; mCMMSE -4.3 to 6.9; CFAB -3.0 to 3.8), exceeding the a priori-defined levels of error.

Conclusion

While the remote and F2F cognitive assessments demonstrated good overall reliability, the test scores were higher when performed remotely compared to F2F. The discrepancies in agreement warrant attention to patient selection and environment optimization for the successful adaptation of telemedicine for cognitive assessment.

Telemedicine Applications in the Era of COVID-19: Telesurgery Issues

Telemedicine allows for the effective delivery of health care to patients at a distance through the application of information technology to the field of medicine. This is optimal during the COVID-19 pandemic to reduce interpersonal contact to mitigate contagion. Among the possible Telemedicine applications, there is Telesurgery, which involves more and more surgical specialties thanks to the numerous benefits in quality and cost containment. In the growing field of Telesurgery, its technical and legal implications must be considered. In this study, a traditional review of the scientific literature was carried out to identify the most relevant issues of interest in Telesurgery. The problematic legal aspects identified are mainly related to the difference in legislation between different geographical areas, which is critical in the case of malpractice. In addition, there is the possibility of a malicious hacker attack on the transmitted data stream either to steal sensitive data or to harm the patient. Finally, there are inherent difficulties with the technology used, such as latency issues in data transmission. All these critical issues are currently not adequately addressed by current legislation. Therefore, one can only hope for a legislative action to allow Telesurgery to be used safely.

Tele-neuropsychological assessment tools in Italy: a systematic review on psychometric properties and usability

Background

The current COVID-19 pandemic has abruptly catalysed a shift towards remote assessment in neuropsychological practice (tele-neuropsychology, t-NPs). Although the validity of t-NPs diagnostics is gaining recognition worldwide, little is known about its implementation in Italy. The present review by the Italian working group on tele-neuropsychology (TELA) aims at describing the availability, psychometric properties, and feasibility of t-NPs tools currently available in Italy.

Methods

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. This work was pre-registered on the Prospective Register of Systematic Reviews (PROSPERO; CRD42021239687). Observational studies reporting telephone-, videoconference- or web-based assessment of cognition/behaviour in Italian both healthy participants (HPs) and patients were included. Bias assessment was performed through ad hoc scales.

Results

Fourteen studies were included from an initial N = 895 (4 databases searched). Studies were subdivided into those focused on psychometric properties and those characterized by a predominant applied nature. The majority of studies addressed either adult/elderly HPs or neurological/internal patients. Multi-domain screening tools for cognition, behaviour, mood/anxiety and quality of life were the most represented. Findings regarding validity, reliability, sensitivity, specificity and clinical usability were reported for cognitive screenings — the telephone- and videoconference-based Mini-Mental State Examination and the Telephone Interview for Cognitive Status.

Discussion

Positive albeit preliminary evidence regarding psychometric properties and feasibility in both clinical and non-clinical populations of Italian t-NPs brief screening tools are herewith provided. Further studies exploring clinical usability of t-NPs and psychometric properties/feasibility of tests for the in-depth assessment of specific cognitive domains are necessary.

Scoping review: the empowerment of Alzheimer's Disease caregivers with mHealth applications

Alzheimer's Disease (AD) is one of the most prevalent neurodegenerative chronic diseases. As it progresses, patients become increasingly dependent, and their caregivers are burdened with the increasing demand for managing their care. Mobile health (mHealth) technology, such as smartphone applications, can support the need of these caregivers. This paper examines the published academic literature of mHealth applications that support the caregivers of AD patients. Following the PRISMA for scoping reviews, we searched published literature in five electronic databases between January 2014 and January 2021. Twelve articles were included in the final review. Six themes emerged based on the functionalities provided by the reviewed applications for caregivers. They are tracking, task management, monitoring, caregiver mental support, education, and caregiver communication platform. The review revealed that mHealth applications for AD patients' caregivers are inadequate. There is an opportunity for industry, government, and academia to fill the unmet need of these caregiver.

Rationale, study design and implementation of the LUCINDA Trial: Leuprolide plus Cholinesterase Inhibition to reduce Neurologic Decline in Alzheimer's

The LUCINDA Trial (Leuprolide plus Cholinesterase Inhibition to reduce Neurologic Decline in Alzheimer's) is a 52 week, randomized, placebo-controlled trial of leuprolide acetate (Eligard) in women with Alzheimer's disease (AD). Leuprolide acetate is a gonadotropin analogue commonly used for hormone-sensitive conditions such as prostate cancer and endometriosis. This repurposed drug demonstrated efficacy in a previous Phase II clinical trial in those women with AD who also received a stable dose of the acetylcholinesterase inhibitor donepezil (Bowen et al., 2015). Basic biological, epidemiological and clinical trial data suggest leuprolide acetate mediates improvement and stabilization of neuropathology and cognitive performance via the modulation of gonadotropin and/or gonadotropin-releasing hormone signaling. LUCINDA will enroll 150 women with mild-moderate AD who are receiving a stable dose of donepezil from three study sites in the United States. Cognition and function are the primary outcome measures as assessed by the Alzheimer's Disease Assessment Scale-Cognitive Subscale. Blood and MRI biomarkers are also measured to assess hormonal, inflammatory and AD biomarker changes. We present the protocol for LUCINDA and discuss trial innovations and challenges including changes necessitated by the covid-19 pandemic and study drug procurement issues.

Tele-Neuropsychological Assessment of Alzheimer's Disease

Background: Because of the new pandemic caused by the novel coronavirus disease (COVID-19), the demand for telemedicine and telemonitoring solutions has been exponentially raised. Because of its special advantage to treat patients in an emergency without physical presence at a hospital via video conferencing, telemedicine has been used to overcome distance barriers and to improve access to special domains like neurology. In these pandemic times, telemedicine has been also employed as a support for the diagnosis and treatment of adult-onset dementia disorders including Alzheimer’s disease. Objective: In this study, we carried out a systematic literature analysis to clarify if the neuropsychological tests traditionally employed in face-to-face (FTF) contexts are reliable via telemedicine. Methods: A systematic literature search for the past 20 years (2001–2020) was carried out through the medical databases PubMed (Medline) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). The quality assessment was conducted by adopting the Newcastle Ottawa Scale (NOS) and only studies with a NOS ≥ 7 were included in this review. Results: The Mini-Mental State Examination (MMSE) results do not differ when tests are administered in the traditional FTF modality or by videoconference, and only negligible minor changes in the scoring system were noticeable. Other neuropsychological tests used to support the diagnosis of AD and dementia such as the Token Test, the Comprehension of Words and Phrases (ACWP), the Controlled Oral Word Association Test showed high reliability between the two modalities considered. No differences in the reliability concerning the living setting or education of the subjects were reported. Conclusions: The MMSE, which is the main screening test for dementia, can be administered via telemedicine with minor adaptation in the scoring system. Telemedicine use for other neuropsychological tests also resulted in general reliability and enough accuracy. Cognitive assessment by videoconference is accepted and appreciated and therefore can be used for dementia diagnosis in case of difficulties to performing FTF assessments. This approach can be useful given a personalized medicine approach for the treatment of adult-onset dementia disorders.

Telemedicine and Dementia Care: A Systematic Review of Barriers and Facilitators

OBJECTIVES

An increasing reliance on telemedicine for older adults with cognitive impairment requires a better understanding of the barriers and facilitators for this unique patient population.

DESIGN

The study team queried PubMed, Embase, the Cochrane Library, PsycINFO, CINAHL, Scopus, and ClinicalTrials.gov on May 1, 2020, for studies in English published from January 2010 to May 2020.

SETTING AND PARTICIPANTS

We conducted a systematic review of articles investigating the use of telemedicine among older adults with Alzheimer's disease and related dementia (ADRD) or mild cognitive impairment (MCI) that focused on the patient and care partner perspectives.

METHODS

Telemedicine encounter purpose, technological requirements, and findings regarding sensory needs were extracted. The Cochrane Collaboration's Risk of Bias Tool was applied for quality assessment.

RESULTS

The search yielded 3551 abstracts, from which 90 articles were reviewed and 17 were included. The purpose of telemedicine encounters included routine care, cognitive assessment, and telerehabilitation. All studies reported successful implementation of telemedicine, supported by patient and care partner satisfaction, similar results on cognitive assessment and diagnosis compared to in-person visits, and improvement in outcome measures following rehabilitation. Sixteen studies relied on staff and care partners to navigate technologies. Six studies reported participants reporting difficulty hearing the provider during the telemedicine visits. Five studies excluded participants with visual or hearing impairment because of the potential difficulty of using telemedicine technology. No studies reported technological adaptations to account for sensory impairment.

CONCLUSIONS AND IMPLICATIONS

Telemedicine is well received among patients and care partners, but successful delivery incorporates support staff and the care partners to navigate technologies. The exclusion of older adults with sensory impairment, especially given that it is highly prevalent, in developing telemedicine systems may further exacerbate access to care in this population. Adapting technologies for sensory needs is critical to the advancement of accessible dementia care through telemedicine.

Digital delivery of non-pharmacological intervention programmes for people living with dementia during the COVID-19 pandemic

The COVID-19 pandemic significantly impeded face-to-face health and social care delivery for people living with dementia and their carers. Interruption of meaningful activity engagement along with increased social isolation is known to be associated with loss of skills, increased loneliness, physical deterioration and decline in cognition and mood in people with dementia. To ensure continuity of care for people living with dementia, for whom multimodal, non-pharmacological intervention programmes were being provided, there was an urgent need to adopt a remote delivery model. Guidance on digitally delivered assessment and care specific to non-pharmacological interventions for dementia is lacking. Adoption of technology-enabled care for people with dementia requires overcoming barriers to technology use, adaptation of therapeutic guidelines, adaptation of communication methods and carer support. Despite these challenges, therapists successfully transitioned from in-person to digital delivery of therapeutic interventions with associated benefits of continued meaningful activity engagement discussed.

Designing and Implementing an IT Architecture for a Digital Multicenter Dementia Registry: digiDEM Bayern

Background  Registries are an essential research tool to investigate the long-term course of diseases and their impact on the affected. The project digiDEM Bayern will set up a prospective dementia registry to collect long-term data of people with dementia and their caregivers in Bavaria (Germany) supported by more than 300 research partners.

Objective  The objective of this article is to outline an information technology (IT) architecture for the integration of a registry and comprehensive participant management in a dementia study. Measures to ensure high data quality, study governance, along with data privacy, and security are to be included in the architecture.

Methods  The architecture was developed based on an iterative, stakeholder-oriented process. The development was inspired by the Twin Peaks Model that focuses on the codevelopment of requirements and architecture. We gradually moved from a general to a detailed understanding of both the requirements and design through a series of iterations. The experience learned from the pilot phase was integrated into a further iterative process of continuous improvement of the architecture.

Results  The infrastructure provides a standardized workflow to support the electronic data collection and trace each participant's study process. Therefore, the implementation consists of three systems: (1) electronic data capture system for Web-based or offline app-based data collection; (2) participant management system for the administration of the identity data of participants and research partners as well as of the overall study governance process; and (3) videoconferencing software for conducting interviews online. First experiences in the pilot phase have proven the feasibility of the framework.

Conclusion  This article outlines an IT architecture to integrate a registry and participant management in a dementia research project. The framework was discussed and developed with the involvement of numerous stakeholders. Due to its adaptability of used software systems, a transfer to other projects should be easily possible.

Pilot Study to Assess the Feasibility of a Mobile Unit for Remote Cognitive Screening of Isolated Elderly in Rural Areas

Background: Given the current COVID-19 pandemic situation, now more than ever, remote solutions for assessing and monitoring individuals with cognitive impairment are urgently needed. Older adults in particular, living in isolated rural areas or so-called ‘medical deserts’, are facing major difficulties in getting access to diagnosis and care. Telemedical approaches to assessments are promising and seem well accepted, reducing the burden of bringing patients to specialized clinics. However, many older adults are not yet adequately equipped to allow for proper implementation of this technology. A potential solution could be a mobile unit in the form of a van, equipped with the telemedical system which comes to the patients’ home. The aim of this proof-of-concept study is to evaluate the feasibility and reliability of such mobile unit settings for remote cognitive testing. Methods and analysis: eight participants (aged between 69 and 86 years old) from the city of Digne-Les-Bains volunteered for this study. A basic neuropsychological assessment, including a short clinical interview, is administered in two conditions, by telemedicine in a mobile clinic (equipped van) at a participants’ home and face to face in a specialized clinic. The administration procedure order is randomized, and the results are compared with each other. Acceptability and user experience are assessed among participants and clinicians in a qualitative and quantitative manner. Measurements of stress indicators were collected for comparison. Results: The analysis revealed no significant differences in test results between the two administration procedures. Participants were, overall, very satisfied with the mobile clinic experience and found the use of the telemedical system relatively easy. Conclusion: A mobile unit equipped with a telemedical service could represent a solution for remote cognitive testing overcoming barriers in rural areas to access specialized diagnosis and care.

A survey of smartphone and interactive video technology use by participants in Alzheimer's disease research: Implications for remote cognitive assessment

INTRODUCTION

Participants from a longitudinal cohort study were surveyed to evaluate the practical feasibility of remote cognitive assessment.

METHODS

All active participants/informants at the University of California San Diego Alzheimer's Disease Research Center were invited to complete a nine-question survey assessing technology access/use and willingness to do cognitive testing remotely.

RESULTS

Three hundred sixty-nine of 450 potential participants/informants (82%) completed the survey. Overall, internet access (88%), device ownership (77%), and willingness to do cognitive testing remotely (72%) were high. Device access was higher among those with normal cognition (85%) or cognitive impairment (85%) than those with dementia (52%), as was willingness to do remote cognitive testing (84%, 74%, 39%, respectively). Latinos were less likely than non-Latinos to have internet or device access but were comparable in willingness to do remote testing.

DISCUSSION

Remote cognitive assessment using interactive video technology is a practicable option for nondemented participants in longitudinal studies; however, additional resources will be required to ensure representative participation of Latinos.

Reliability of Telephone and Videoconference Methods of Cognitive Assessment in Older Adults with and without Dementia

BACKGROUND

Telephone and videoconference administration of cognitive tests introduce additional sources of variance compared to in-person testing. Reviews of test-retest reliability have included mixed neurocognitive and psychiatric populations with limited consideration of methodological and statistical contributions.

OBJECTIVE

We reviewed reliability estimates from comparison studies of older adults with and without dementia, considering test-retest analyses and study methods.

METHODS

Medline, Embase, PsycINFO, and Web of Science were systematically searched from 1 January 2000 to 9 June 2020 for original articles comparing telephone or videoconference administered cognitive instruments to in-person administration in older adults with and without dementia or mild cognitive impairment.

RESULTS

Of 4,125 articles, 23 were included: 11 telephone (N = 2 dementia cohorts) and 12 videoconference (N = 4 dementia cohorts). Telephone administered subtest scores trended in the same direction as in-person with comparable means. Person-level data were scarce. Data on dementia was only available for MMSE, with resulting subtle modality bias. MMSE, SMMSE, Letter Fluency, and HVLT-R in healthy to mild-moderate Alzheimer's disease were particularly reliable for videoconference administration. Other tests show promise but require more observations and comprehensive analyses. Most studies used high-speed stable videoconferencing hardware resulting in a lack of ecological validity for home administration.

CONCLUSION

Remote administration is often consistent with in-person administration but variable and limited at the person/test level. Improved statistical design and inclusion of dementia related cohorts in telephone studies is recommended. Reliability evidence is stronger for videoconferencing but with limited applicability to home administration and severe dementia. Improved reporting of administrative procedures is recommended.

Telehealth in Neurodegenerative Diseases: Opportunities and Challenges for Patients and Physicians

Telehealth, by definition, is distributing health-related services while using electronic technologies. This narrative Review describes the technological health services (telemedicine and telemonitoring) for delivering care in neurodegenerative diseases, Alzheimer's disease, Parkinson's Disease, and amyotrophic lateral Sclerosis, among others. This paper aims to illustrate this approach's primary experience and application, highlighting the strengths and weaknesses, with the goal of understanding which could be the most useful application for each one, in order to facilitate telehealth improvement and use in standard clinical practice. We also described the potential role of the COVID-19 pandemic to speed up this service's use, avoiding a sudden interruption of medical care.

Feasibility study of assessing the Preclinical Alzheimer Cognitive Composite (PACC) score via videoconferencing

Background

The Preclinical Alzheimer Cognitive Composite (PACC) is a composite score which can detect the first signs of cognitive impairment, which can be of importance for research and clinical practice. It is designed to be administered in person; however, in-person assessments are costly, and are difficult during the current COVID-19 pandemic.

Objective

To assess the feasibility of performing the PACC assessment with videoconferencing, and to compare the validity of this remote PACC with the in-person PACC obtained previously.

Methods

Participants from the HEalth and Ageing Data IN the Game of football (HEADING) Study who had already undergone an in-person assessment were re-contacted and re-assessed remotely. The correlation between the two PACC scores was estimated. The difference between the two PACC scores was calculated and used in multiple linear regression to assess which variables were associated with a difference in PACC scores.

Findings

Of the 43 participants who were invited to this external study, 28 were re-assessed. The median duration in days between the in-person and the remote assessments was 236.5 days (7.9 months) (IQR 62.5). There was a strong positive correlation between the two assessments for the PACC score, with a Pearson correlation coefficient of 0·82 (95% CI 0·66, 0·98). The multiple linear regression found that the only predictor of the PACC difference was the time between assessments.

Interpretation

This study provides evidence on the feasibility of performing cognitive tests online, with the PACC tests being successfully administered through videoconferencing. This is relevant, especially during times when face-to-face assessments cannot be performed.

Saving cognitive outcome data in Alzheimer's disease clinical trials during the COVID-19 pandemic: Commentary on the virtual administration of the ADAS-Cog

Elderly participants in Alzheimer's disease (AD) clinical trials are at high risk of morbidity and mortality with interpersonal exposure to COVID-19, a situation that is likely to continue for the foreseeable future. Yet, in-person neuropsychological assessments remain the mainstay primary outcomes for clinical trials seeking prevention and cure for AD. The Alzheimer's Disease Assessment Scale-Cognitive (ADAS-Cog) is among the most commonly used cognitive assessment in AD clinical trials, and though currently lacking specific guidelines for virtual administrations, it can be used remotely with appropriate modifications and considerations. Here we propose a novel method of virtual administration of the ADAS-Cog, which considers workarounds for technological and human limitations imposed when the participant is no longer sitting across from the test administrator.

Clinical Trials and Tribulations in the COVID-19 Era

Advances in treating and preventing Alzheimer disease and other neurocognitive disorders of aging arise from rigorous preclinical and clinical research, with randomized controlled treatment trials as the last and definitive test. The COVID-19 pandemic has greatly disrupted ongoing interventional studies and researchers are scrambling to find ways to safely continue this critical work amidst rapidly shifting guidelines from sponsors, institutions, and state and federal guidelines. Here the authors describe novel approaches and work-flow adaptations to study visits, drug delivery and interim and endpoint safety and outcomes assessments to avoid sacrificing years of preparation and substantial financial investments, to work in the best interest of participants and their caregivers, and to continue on the path toward discovering disease-modifying treatments for the millions of individuals impacted by major neurocognitive disorders.

Telemedicine: A valuable tool in neurodegenerative diseases

Purpose of Review

The prevalence of neurodegenerative diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD), is rising as the global population ages. Access to specialist care, which improves outcomes, is insufficient and disease-related disability makes in-person physician visits burdensome. Telehealth is one potential means for improving access to care. The purpose of this manuscript is to review recent publications on telemedicine in AD and PD.

Recent Findings

Telemedicine is feasible in AD and PD and acceptable to patients and their caregivers. Compared with in-person visits, telemedicine reduces visit-associated travel and time. Telemedicine can be used for rehabilitative therapies, to administer cognitive tests, and to support caregivers. Access to telemedicine results in changes in patient care including medication adjustments and referrals for therapies and supports.

Summary

The use of telemedicine in AD and PD stands to decrease burden on patients and increase access to specialty care. Barriers to the expansion of telemedicine care include lack of widespread broadband access, state licensure requirements, and inconsistent reimbursement. More outcomes-based prospective telemedicine studies are needed.

Home Virtual Visits for Outpatient Follow-Up Stroke Care: Cross-Sectional Study

Background

Timely, in-person access to health care is a challenge for people living with conditions such as stroke that result in frailty, loss of independence, restrictions in driving and mobility, and physical and cognitive decline. In Southeastern Ontario, access is further complicated by rurality and the long travel distances to visit physician clinics. There is a need to make health care more accessible and convenient. Home virtual visits (electronic visits, eVisits) can conveniently connect physicians to patients. Physicians use a secure personal videoconferencing tool to connect to patients in their homes. Patients use their device of choice (smartphone, tablet, laptop, or desktop) for the visit.

Objective

This study aimed to assess the feasibility and logistics of implementing eVisits in a stroke prevention clinic for seniors.

Methods

A 6-month eVisit pilot study was initiated in the Kingston Health Sciences Centre stroke prevention clinic in August 2018. eVisits were used only for follow-up patient encounters. An integrated evaluation was used to test the impact of the program on clinic workflow and patient satisfaction. Patient satisfaction was evaluated by telephone interviews, using a brief questionnaire. Access and patient satisfaction metrics were compared with concurrent standard of care (patients’ prior personal experience with in-person visits). Values are presented as median (interquartile range).

Results

There were 75 subjects in the pilot. The patients were aged 65 (56-73.5) years, and 39% (29/75) resided in rural areas. There was a shorter wait for an appointment by eVisit versus in-person (mean 59.98 [SD 48.36] days vs mean 78.36 [SD 50.54] days; P<.001). The eVisit was also shorter, taking on an average of only 10 min to deliver follow-up care with a high degree of patient satisfaction versus 90 (60-112) min for in-person care. The total time saved by patients per eVisit was 80 (50-102) min, 44 (21-69) min of which was travel time. Travel distance avoided by the patients was 30.1 km (11.2-82.2). The estimated total out-of-pocket cost savings for patients per eVisit was Can $52.83 (31.26-94.53). The estimated savings (opportunity cost for in-person outpatient care) for our eVisit pilot project was Can $23,832-$28,584. The patient satisfaction with eVisits was very good compared with their prior personal experience with in-person outpatient care.

Conclusions

The eVisit program was well received by patients, deemed to be safe by physicians, and avoided unnecessary patient travel and expense. It also has the potential to reduce health care costs. We plan to scale the project within the department and the institution.

Social Aspects of Dementia Prevention from a Worldwide to National Perspective: A Review on the International Situation and the Example of Italy

At the moment, dementia is affecting around 47 million people worldwide, with a forecast amount of 135 million affected people in 2050. Dementia is a growing health concern worldwide with no treatment currently available, but only symptomatic medication. Effective interventions in the prevention and management of dementia are urgently needed to contain direct and indirect costs of this disease. Indeed, the economic impact of dementia is a vast and continually growing figure, but it is still difficult to quantify. Due to an increase in both the disease spreading and its direct and indirect costs, national and international action plans have to be implemented. As a virtuous example, the Italian national plan for dementia has been summarized. Faced with an increasingly less sustainable disease impact at national and international levels, the plan suggests that it is certainly the entire welfare model that should be rethought, strengthening the network of services and providing interventions to support affected people and their caregivers. Alongside this synergistic approach, scientific research could play a crucial role for pharmacological and nonpharmacological treatments capable of delaying the state of loss of self-sufficiency of the patient, with a significant impact on social and health costs.

Cognitive assessment using face-to-face and videoconferencing methods

BACKGROUND

Early and regular assessment is needed to identify cognitive impairment in older adults. The use of telehealth or telecognitive assessment is widely applied in some aspects of health services, but it is unclear if cognitive assessments conducted in this way are reliable.

AIM

To examine whether using a handheld device to complete a cognitive assessment in adults can provide reliable scores, whether participants would be satisfied to complete a cognitive assessment by videoconference and if they would prefer face-to-face or telehealth assessment, and what challenges might be associated with telecognitive assessment using a handheld device compared with using face-to-face methods.

METHOD

Participants ( n =27) were given a series of cognitive assessments face to face and using a handheld device. Results were examined for reliability, logistical and technical challenges, and participants were questioned about which they preferred.

RESULTS

Cognitive assessments made with the handheld device were effective and reliable, and produced results that were comparable to those made with face-to-face assessments. However, more participants preferred face-to-face assessments than handheld device assessments. Several technical limitations were also noted during the assessments made using the handheld devices.

CONCLUSION

Although scores made using the handheld device were reliable, preliminary evidence suggests there are some tangible barriers to integrating telehealth into all settings for all patients.

Geriatric Telepsychiatry: Systematic Review and Policy Considerations

Telemental health (TMH) for older patients has the potential to increase access to geriatric specialists, reduce travel times for patients and providers, and reduce ever growing healthcare costs. This systematic review article examines the literature regarding psychiatric assessment and treatment via telemedicine for geriatric patients. English language literature was searched using Ovid Medline, PubMed, and PsycINFO with search terms including telemedicine, telemental health, aging, and dementia. Abstracts were reviewed for relevance based on inclusion criteria. Multiple study types were reviewed, including open label, qualitative and randomized controlled trial study designs. Data was compiled regarding participants, study intervention, and outcomes. 76 articles were included. TMH was shown to be feasible and well accepted in the areas of inpatient and nursing home consultation, cognitive testing, dementia diagnosis and treatment, depression in integrated and collaborative care models, and psychotherapy. There is limited data on cost-effectiveness of TMH in the elderly. This article will discuss the current barriers to broader implementation of telemedicine for geriatric patients including reimbursement from the Medicare program. Medicare reimbursement for telemedicine is limited to rural areas, which does not allow for the widespread development of telemedicine programs. All Medicare beneficiaries would benefit from increased access to telemedicine services, not only those living in rural areas. As many elderly and disabled individuals have mobility problems, home-based telemedicine services should also be made available. There are efforts in Congress to expand the coverage of these services under Medicare, but strong advocacy will be needed to ensure these efforts are successful.
