Telehealth Management of Dysphagia in Adults: A Survey of Speech Language Pathologists' Experiences and Perceptions.

The goal of this study was to explore telehealth use for dysphagia management in response to COVID-19 to understand variables associated with clinician confidence and perceived effectiveness of this service delivery model and determine clinician-perceived benefits and challenges of managing dysphagia via telehealth. Speech-language pathologists (SLPs, n = 235) completed a web-based survey, providing information on demographics, telehealth use during the pandemic, and perspectives on current and future tele-management of dysphagia. Analyses included descriptive statistics to examine usage patterns; logistic regression to determine which variables were associated with telehealth use, clinician confidence, and perceived-effectiveness; and conventional content analysis to analyze responses to open-ended questions. Results revealed a sharp increase in the tele-management of dysphagia during the pandemic. Years of experience with dysphagia management (p = .031) and pre-pandemic use of telehealth (p < .001) were significantly associated with current use patterns. Working in the outpatient setting was associated with greater clinician confidence (p = .003) and perceived effectiveness (p = .007), and use of guidelines (p = .042) was also associated with greater clinician confidence. Key challenges identified included inadequate technological infrastructure, inadequate patient digital literacy, and reimbursement restrictions. Key benefits were treatment continuity, improving access to care, and time savings. The majority (67%) of respondents reported that they would use telehealth in the future. These findings demonstrate SLPs' abilities and desire to expand their practice patterns to include telehealth for dysphagia management. Therefore, clinician training and more research on best practices for assessment and treatment of dysphagia via telehealth is warranted to refine models of care for dysphagia tele-management.

Telehealth for Dysphagia Across the Life Span: Using Contemporary Evidence and Expertise to Guide Clinical Practice During and After COVID-19.

Purpose Our aim was to critically review recent literature on the use of telehealth for dysphagia during the COVID-19 pandemic and enhance this information in order to provide evidence- and practice-based clinical guidance during and after the pandemic. Method We conducted a rapid systematized review to identify telehealth adaptations during COVID-19, according to peer-reviewed articles published from January to August 2020. Of the 40 articles identified, 11 met the inclusion criteria. Full-text reviews were completed by three raters, followed by qualitative synthesis of the results and description of practical recommendations for the use of telehealth for dysphagia. Results Seven articles were guidelines articles, three were editorials, and one was a narrative review. One article focused on telehealth and dysphagia during COVID-19. The remaining 10 mentioned telehealth in varying degrees while focusing on dysphagia management during the pandemic. No articles discussed pediatrics in depth. The most common procedure for which telehealth was recommended was the clinical swallowing assessment (8/11), followed by therapy (7/11). Six articles characterized telehealth as a second-tier service delivery option. Only one article included brief guidance on telehealth-specific factors, such as legal safeguards, safety, privacy, infrastructure, and facilitators. Conclusions Literature published during the pandemic on telehealth for dysphagia is extremely limited and guarded in endorsing telehealth as an equivalent service delivery model. We have presented prepandemic and emerging current evidence for the safety and reliability of dysphagia telemanagement, in combination with practical guidelines to facilitate the safe adoption of telehealth during and after the pandemic.

Objective and Subjective Clinical Swallowing Outcomes via Telehealth: Reliability in Outpatient Clinical Practice.

Purpose The COVID-19 pandemic has drastically increased the use of telehealth. Prior studies of telehealth clinical swallowing evaluations provide positive evidence for telemanagement of swallowing. However, the reliability of these measures in clinical practice, as opposed to well-controlled research conditions, remains unknown. This study aimed to investigate the reliability of outcome measures derived from clinical swallowing tele-evaluations in real-world clinical practice (e.g., variability in devices and Internet connectivity, lack of in-person clinician assistance, or remote patient/caregiver training). Method Seven raters asynchronously judged clinical swallowing tele-evaluations of 12 movement disorders patients. Outcomes included the Timed Water Swallow Test (TWST), Test of Masticating and Swallowing Solids (TOMASS), and common observations of oral intake. Statistical analyses were performed to examine inter- and intrarater reliability, as well as qualitative analyses exploring patient and clinician-specific factors impacting reliability. Results Forty-four trials were included for reliability analyses. All rater dyads demonstrated "good" to "excellent" interrater reliability for measures of the TWST (intraclass correlation coefficients [ICCs] ≥ .93) and observations of oral intake (≥ 77% agreement). The majority of TOMASS outcomes demonstrated "good" to "excellent" interrater reliability (ICCs ≥ .84), with the exception of the number of bites (ICCs = .43-.99) and swallows (ICCs = .21-.85). Immediate and delayed intrarater reliability were "excellent" for most raters across all tasks, ranging between ICCs of .63 and 1.00. Exploratory factors potentially impacting reliability included infrequent instances of suboptimal video quality, reduced camera stability, camera distance, and obstruction of the patient's mouth during tasks. Conclusions Subjective observations of oral intake and objective measures taken from the TWST and the TOMASS can be reliably measured via telehealth in clinical practice. Our results provide support for the feasibility and reliability of telehealth for outpatient clinical swallowing evaluations during COVID-19 and beyond.

Validation of a Novel Wearable Electromyography Patch for Monitoring Submental Muscle Activity During Swallowing: A Randomized Crossover Trial.

Purpose Surface electromyography (sEMG) is often used for biofeedback during swallowing rehabilitation. However, commercially available sEMG electrodes are not optimized for the head and neck area, have rigid form, and are mostly available in large medical centers. We developed an ultrathin, soft, and flexible sEMG patch, specifically designed to conform to the submental anatomy and which will be ultimately incorporated into a telehealth system. To validate this first-generation sEMG patch, we compared its safety, efficiency, and signal quality in monitoring submental muscle activity with that of widely used conventional sEMG electrodes. Method A randomized crossover design was used to compare the experimental sEMG patch with conventional (snap-on) sEMG electrodes. Participants completed the same experimental protocol with both electrodes in counterbalanced order. Swallow trials included five trials of 5- and 10-ml water. Comparisons were made on (a) signal-related factors: signal-to-noise ratio (SNR), baseline amplitude, normalized mean amplitude, and sEMG burst duration and (b) safety/preclinical factors: safety/adverse effects, efficiency of electrode placement, and satisfaction/comfort. Noninferiority and equivalence tests were used to examine signal-related factors. Paired t tests and descriptive statistics were used to examine safety/preclinical factors. Results Forty healthy adults participated (24 women, M age = 67.5 years). Signal-related factors: SNR of the experimental patch was not inferior to the SNR of the conventional electrodes (p < .0056). Similarly, baseline amplitude obtained with the experimental patch was not inferior to that obtained with conventional electrodes (p < .0001). Finally, normalized amplitude values were equivalent across swallows (5 ml: p < .025; 10 ml: p < .0012), and sEMG burst duration was also equivalent (5 ml: p < .0001; 10 ml: p < .0001). Safety/preclinical factors: The experimental patch resulted in fewer mild adverse effects. Participant satisfaction was higher with the experimental patch (p = .0476, d = 0.226). Conclusions Our new wearable sEMG patch is equivalent with widely used conventional sEMG electrodes in terms of technical performance. In addition, our patch is safe, and healthy older adults are satisfied with it. With lessons learned from the current COVID-19 pandemic, efforts to develop optimal swallowing telerehabilitation devices are more urgent than ever. Upon further validation, this new technology has the potential to improve rehabilitation and telerehabilitation efforts for patients with dysphagia.

Dysphagia Care Across the Continuum: A Multidisciplinary Dysphagia Research Society Taskforce Report of Service-Delivery During the COVID-19 Global Pandemic.

At the time of writing this paper, there are over 11 million reported cases of COVID-19 worldwide. Health professionals involved in dysphagia care are impacted by the COVID-19 pandemic in their day-to-day practices. Otolaryngologists, gastroenterologists, rehabilitation specialists, and speech-language pathologists are subject to virus exposure due to their proximity to the aerodigestive tract and reliance on aerosol-generating procedures in swallow assessments and interventions. Across the globe, professional societies and specialty associations are issuing recommendations about which procedures to use, when to use them, and how to reduce the risk of COVID-19 transmission during their use. Balancing safety for self, patients, and the public while maintaining adequate evidence-based dysphagia practices has become a significant challenge. This paper provides current evidence on COVID-19 transmission during commonly used dysphagia practices and provides recommendations for protection while conducting these procedures. The paper summarizes current understanding of dysphagia in patients with COVID-19 and draws on evidence for dysphagia interventions that can be provided without in-person consults and close proximity procedures including dysphagia screening and telehealth.
