The basic theory and application of the mirror neuron system in dysphagia after stroke

The discovery of the brain's mirror neuron system enables researchers to gain a deeper understanding of social cognitive activities from the level of neural mechanisms. Mirror neurons are situated in bilateral brain regions, overlapping with the swallowing neural network, and there are complex network pathways connecting the two. Repeatedly inducing the activation of mirror neurons in stroke patients can enhance the brain's ability to relearn its original swallowing function, and then restore the swallowing neural network. With the deepening of related studies, rehabilitation therapies based on the mirror neuron system have been discussed and explored by numerous scholars and applied to the rehabilitation of dysphagia after stroke. In this paper, we review the basic theory of mirror neuron system, its mechanism, its relevance to the swallowing neural network, and the clinical application and research progress of related rehabilitation therapies in stroke dysphagia, with a view to triggering relevant researchers to comprehend and innovate the rehabilitation of dysphagia after stroke.

Advances in wearable electronics for monitoring human organs: Bridging external and internal health assessments

Devices used for diagnosing disease are often large, expensive, and require operation by trained professionals, which can result in delayed diagnosis and missed opportunities for timely treatment. However, wearable devices are being recognized as a new approach to overcoming these difficulties, as they are small, affordable, and easy to use. Recent advancements in wearable technology have made monitoring information possible from the surface of organs like the skin and eyes, enabling accurate diagnosis of the user's internal status. In this review, we categorize the body's organs into external (e.g., eyes, oral cavity, neck, and skin) and internal (e.g., heart, brain, lung, stomach, and bladder) organ systems and introduce recent developments in the materials and designs of wearable electronics, including electrochemical and electrophysiological sensors applied to each organ system. Further, we explore recent innovations in wearable electronics for monitoring of deep internal organs, such as the heart, brain, and nervous system, using ultrasound, electrical impedance tomography, and temporal interference stimulation. The review also addresses the current challenges in wearable technology and explores future directions to enhance the effectiveness and applicability of these devices in medical diagnostics. This paper establishes a framework for correlating the design and functionality of wearable electronics with the physiological characteristics and requirements of various organ systems.

Validity and Reliability of the Swedish Version of the Gugging Swallowing Screen for use in Acute Stroke Care

The purpose of this study was to cross-culturally validate the Swedish version of the Gugging Swallowing Screen (GUSS-S) for use in the acute phase of stroke. Further, to evaluate the inter-rater reliability between different healthcare professionals. GUSS was translated into Swedish using a forward-backward method followed by expert rating to obtain content validity. For criterion validity, the GUSS-S score was compared with Flexible Endoscopic Evaluation of Swallowing (FEES) assessed with the Penetration-Aspiration Scale (PAS) in acute stroke patients (≤ 96 h after stroke onset). Convergent validity was calculated by comparison with the Functional Oral Intake Scale (FOIS) as per the comprehensive FEES assessment, the Standardized Swallowing Assessment (SSA), and the National Institutes of Health Stroke Scale (NIHSS). To evaluate inter-rater reliability, a nurse and a speech-language pathologist (SLP) independently assessed 30 patients. In total, 80 patients (32 women, median age 77 years (range 29-93) were included, mean 1.7 ± 0.9 days after admission. With a cut-off value of 14 points, the GUSS-S identified aspiration with a sensitivity of 100% and a specificity of 73% (area under the curve: 0.87, 95% CI 0.78-0.95). Spearman rank correlation showed very strong correlation between the GUSS-S and PAS (rs=-0.718, P = < 0.001) and FOIS (rs=0.720, P = 0.001) and strong correlation between the GUSS-S and SSA (rs=0.545, P = < 0.001) and NIHSS (rs=-0.447, P = 0.001). The inter-rater agreement for GUSS-S was substantial (Kw=0.67, P = < 0.001). The results indicate that the GUSS-S is a valid and reliable tool for the assessment of dysphagia in acute stroke patients by different healthcare professionals.

Optimizing Tilapia-based surimi ink for 3D printing: Enhancing physicochemical properties and printability with Ulva powder

The elderly face malnutrition and dysphagia. 3D printing with high-protein surimi offers an innovative way to customize nutrition and texture of foods for the elderly. This study explored whether tilapia-based surimi ink (TBSI) with Ulva powder (UP, 0-3 %) could improve physicochemical properties and printability as an alternative to traditional pollock-based surimi ink (PBSI). TBSI showed a more uniform microstructure, greater water-holding capacity (WHC), and better printability with consistent extrusion than PBSI. Adding UP to TBSI promoted cross-linking and enhanced microstructure and WHC. Rheological analysis revealed that all inks exhibited shear-thinning behavior. UP increased complex viscosity, storage modulus, and loss modulus. Notably, UP above 2 % improved protein matrix uniformity, structural integrity, and printability, as confirmed by FT-IR and 3D printing tests. The hardness of steamed TBSI fish cake increased when infill density increased. This study highlights the potential of TBSI with UP for 3D printing to prepare personalized and elderly-friendly food.

Development of a Screening Intervention for Dysphagia in Hospitalised Geriatric Patients

Prevalence of dysphagia is high in hospitalised geriatric patients, posing risks of complications including malnutrition, dehydration, aspiration, and pneumonia. These complications may lead to reduced daily functioning, frailty, prolonged hospital stays, readmissions, and mortality. Diagnosing dysphagia in geriatric patients is often challenging due to the complex health conditions of this patient group, and overall these patients are at risk of lack of continuity in patient pathways and unnecessary hospitalisations. Recognising the critical importance of prompt diagnosis and treatment of dysphagia, we developed a dysphagia screening intervention aligned with clinical guidelines and the political focus to improve patient pathways and reduce preventable hospitalisations. This article outlines the development process of a dysphagia screening intervention to geriatric patients (≥ 65 years) admitted to medical inpatient wards. We applied a theory-, evidence- and implementation-based approach combined with stakeholder involvement in adherence to the IdentifyiNg and assessing different approaches to DEveloping compleX intervention (INDEX) guidance, encompassing eleven actions. We developed a dysphagia screening intervention comprising a screening procedure (the 4 Questionnaire Test (4QT), the 30 ml water swallowing test, and an action algorithm) targeting the patient level. Moreover, we developed an implementation strategy (activities necessary for adequate delivery of the dysphagia screening procedure and activities supporting the delivery of the screening procedure) targeting health professionals and the organisational level. The dysphagia screening intervention is now ready for feasibility testing, promising improved health and healthcare services for hospitalised geriatric patients.

Perspectives of Hospital Medicine Providers on the Management of Oropharyngeal Dysphagia in Patients with Dementia

BACKGROUND

Oropharyngeal dysphagia (dysphagia) is a common (up to 86%) and devastating syndrome in hospitalized older adults with dementia.

OBJECTIVE

To describe the perspectives of dysphagia management in hospitalized patients with dementia among hospital medicine providers (i.e., hospitalists, internal medicine residents, and advanced practice providers, APPs).

DESIGN

An anonymous cross-sectional survey study across a large health system in the greater New York metropolitan area PARTICIPANTS: Surveys were distributed to hospitalists, internal medicine residents, and APPs via a multimodal approach. Survey questions were created by an interprofessional team consisting of hospitalists, a geriatrician, and a geriatrics-trained APP.

MAIN MEASURES

Survey questions assessed current practices and perceptions of dysphagia management in patients with dementia.

KEY RESULTS

Of 104 surveys completed, 62.1% were hospitalists, 24.3% were APPs, and 13.6% were residents. Nursing report (61.0%) was the most common way providers found out about suspected dysphagia. The vast majority (85.0%) always/often consulted a Speech-Language Pathologist (SLP) for suspected dysphagia evaluation. Over a third (39.8%) rarely/never discussed goals of care before consulting a SLP. Provider perceptions of the risks/benefits of dysphagia diets varied widely: dysphagia diets in patients with dementia improve quality of life (strongly disagree/disagree 33.0%, neither agree or disagree 31.1%, strongly agree/agree 35.9%); dysphagia diets in patients with dementia reduce the risk of mortality (strongly disagree/disagree 33.0%, neither agree or disagree 22.3%, strongly agree/agree 44.7%). Lastly, only 64% thought there was enough evidence to recommend against a PEG in patients with advanced dementia.

CONCLUSION

Our study highlights the need for standardizing dysphagia management best practices in hospitalized patients with dementia, the importance of addressing goals of care, and provider education on the risks and benefits of dysphagia diets and artificial nutrition via PEG tube.

Effects of Capsaicin on Masticatory and Swallowing Function

INTRODUCTION

Recent studies have shown that capsaicin improves the pharyngeal swallowing reflex. However, the mechanism by which capsaicin alters mastication and oesophageal function remains unclear. This study aimed to investigate the effects of capsaicin on masticatory and oesophageal function.

MATERIALS AND METHODS

Participants were 12 healthy individuals (7 men, 5 women: aged 31.5 ± 3.0 years). The participants ingested five rice cakes without capsaicin and then five rice cakes containing capsaicin. Total mastication frequency, total mastication time, and mastication rate were measured. Pharyngeal and upper oesophageal sphincter (UES) parameters were evaluated using high-resolution manometry (HRM). The masticatory and HRM parameters were compared between the ingestion of capsaicin-containing and non-capsaicin containing rice cakes.

RESULTS

The total mastication frequency and total mastication time(s) for capsaicin ingestion were significantly smaller (20.3 ± 9.4 vs. 22.4 ± 7.4; p = 0.011) and shorter (14.2 ± 7.0 vs. 15.4 ± 5.6; p = 0.038), respectively, than those for non-capsaicin ingestion. Comparison of the HRM parameters revealed significantly higher hypopharyngeal contractile integral (mmHg-s-cm) (56.6 ± 40.7 vs. 49.7 ± 43.6; p = 0.016) and proximal oesophageal contractile integral (mmHg-s-cm) (492.3 ± 292.64 vs. 381.2 ± 266; p < 0.001), significantly shorter UES basal pressure (mmHg) (93.6 ± 37.8 vs. 114.5 ± 43.4; p < 0.001), and significantly longer UES relaxation time (ms) (486.7 ± 90.7 vs. 431.2 ± 82.3; p < 0.001) for capsaicin ingestion than for non-capsaicin ingestion.

CONCLUSIONS

Decreased mastication frequency and time, increased hypopharyngeal and proximal oesophageal contractile integral, and prolonged UES opening time with capsaicin ingestion suggests that capsaicin improves oral, pharyngeal and oesophageal phases of swallowing.

Effect of Thickened Fluids on Swallowing Function in Oropharyngeal Dysphagia: Impact of Shear Rheology and Disorder Subtype

INTRODUCTION

Fluid thickeners used in the management of oropharyngeal dysphagia exhibit non-Newtonian shear-thinning rheology, impacting their viscosity during deglutition. This study investigated how the rheological properties of thickened fluids affect pharyngeal swallowing parameters in patients with oropharyngeal motor disorders diagnosed by pharyngeal high-resolution manometry impedance (P-HRM-I).

METHODS

Seventy-two patients (18-89 years) referred for P-HRM-I were diagnostically assessed with a 10 mL thin bolus. In 57 of the patients, 10 mL swallows of two moderately thick formulations-xanthan gum (XG) and sodium carboxymethylcellulose gum (CMC)-were also tested. The XG and CMC fluids had equivalent empirical thickness but different viscosity at pharyngeal phase shear rates: XG 87 mPa.s (83-91) versus CMC mean 157 mPa.s (148-164) at 300 s-1. Standard metrics of pharyngeal and upper esophageal sphincter (UES) function were derived from P-HRM-I recordings and analyzed to characterize patients into one of four disorder subtypes: (i) No Disorder, (ii) UES Disorder, (iii) Pharyngeal Disorder, and (iv) Combination UES/Pharyngeal Disorder. Impedance recordings also assessed pharyngeal bolus transit.

RESULTS

Patients with a Combination UES/Pharyngeal Disorder were most likely to have abnormal bolus transit (82%, p < 0.001). Increasing bolus viscosity significantly influenced UES residual pressure, UES opening area, and post-swallow residue. Patients with UES Disorder exhibited pronounced increases in UES residual pressure with CMC compared to XG. Pharyngeal contractility was unaffected by viscosity changes. Post-swallow residue increased with CMC, particularly in patients with a Combination Disorder. Case-by-case analysis revealed individual variability in response to the different viscosities.

CONCLUSION

The rheological properties of thickened fluids significantly affect swallowing function, with these effects dependent upon the disorder subtype.

Application of Orofacial Muscle Strength Measurement to Screen for Penetration/Aspiration Risk in Older Adults With Sarcopenia: A Diagnostic Accuracy Study

BACKGROUND

Early identification of penetration/aspiration (P/A) risk in older adults with sarcopenia is crucial to prevent complications and maintain quality of life.

PURPOSE

To evaluate the diagnostic utility of orofacial muscle strength measurements for predicting the risk of P/A in older adults with sarcopenia.

METHODS

In this observational and prospective study, we collated consecutive data from community-dwelling older adults diagnosed with sarcopenia at a musculoskeletal disorder clinic. Altogether, 54 participants underwent orofacial muscle strength measurements (the index test) using the Iowa Oral Performance Instrument and a videofluoroscopic swallowing study (VFSS) (the reference test) to evaluate for the presence of P/A. Receiver operating characteristic (ROC) curve analysis was performed to determine orofacial muscle strength based on P/A.

RESULTS

Overall, 34 patients showed penetration in the VFSS, although none of the patients showed signs of aspiration. The cut-off for tongue strength to identify the risk of P/A was ≤ 20.5 kPa, with a sensitivity and specificity of 0.75 and 0.74, respectively; the area under the curve (AUC) was 0.88. The cut-off for buccinator strength was ≤ 19.5 kPa, with a sensitivity and specificity of 0.65 and 0.68, respectively, with an AUC of 0.69. The cut-off for lip muscle strength was ≤ 18.5 kPa, with a sensitivity and specificity of 0.65 and 0.71, respectively, with an AUC of 0.69.

CONCLUSION

The evaluation of buccinator and lip muscle strength did not demonstrate sufficient diagnostic utility for detecting the risk of P/A in older patients with sarcopenia; however, tongue strength showed reliable diagnostic utility for identifying the risk of P/A.

Fish Protein Hydrolysate as Protein Enrichment in Texture-Modified Salmon Products

The aim of this study was to develop a chilled, texture-modified salmon product for dysphagia patients, enriched with dairy and fish hydrolysate proteins. The challenge was to create a product with appealing sensory qualities and texture that meets level 5 (minced & moist) of the IDDSI framework. Atlantic salmon (Salmo salar) was heat-treated (95 °C/15 min), blended, and reconstructed by adding texture modifiers, casein and whey protein, and enzymatically derived fish hydrolysate. The products were packaged in oxygen-free plastic trays, heat-treated to a core temperature of 95 °C for 15 min, chilled and stored at 4 °C for 29 days and analyzed for microbiology, instrumental texture, and sensory properties. The texture analyses showed that products with fish protein hydrolysate were softer than those only with casein and whey protein, a result also confirmed by the IDDSI fork pressure test. Quantitative descriptive analysis of salmon products revealed significant differences (p < 0.05) in sensory attributes within flavour (fish flavour), and texture (softness and adhesiveness) but there was no significant change in bitterness. The shelf-life study at 4 °C showed good microbiological quality of the product, and safety after 29 days with appealing sensory and textural properties, i.e., a product at IDDSI level 5 for age care facilities and commercial production was obtained.

Evaluation of the performance of screening tools for dysphagia in older adults: A diagnostic meta-analysis

This systematic review evaluated the diagnostic accuracy of multiple screening tools for dysphagia in older adults. The analysis covered 30 studies involving 13 tools and 2,697 participants. The results showed that the volume viscosity swallow test performed best in sensitivity, specificity, and area under the curve, making it a recommended screening tool. Other tools have low sensitivity, unstable results or insufficient research and need to be further validated. Overall, this study provides an important reference for the screening of dysphagia in older adults.

Microbiome and Communication Disorders: A Tutorial for Clinicians

PURPOSE

Emerging research in the field of microbiology has indicated that host-microbiota interactions play a significant role in regulating health and disease. Whereas the gut microbiome has received the most attention, distinct microbiota in other organs (mouth, larynx, and trachea) may undergo microbial shifts that impact disease states. A comprehensive understanding of microbial mechanisms and their role in communication and swallowing deficits may have downstream diagnostic and therapeutic implications.

METHOD

A literature review was completed to provide a broad overview of the microbiome, including differentiation of commensal versus pathogenic bacteria; cellular mechanisms by which bacteria interact with human cells; site-specific microbial compositional shifts in certain organs; and available reports of oral, laryngeal, and tracheal microbial dysbiosis in conditions that are associated with communication and swallowing deficits.

RESULTS/CONCLUSIONS

This review article is a valuable tutorial for clinicians, specifically introducing them to the concept of dysbiosis, with potential contributions to communication and swallowing deficits. Future research should delineate the role of specific pathogenic bacteria in disease pathogenesis to identify therapeutic targets.

Oropharyngeal dysphagia impact of pneumonia risk in neurological patients receiving enteral tube feeding: Insights from a gastroenterologist

BACKGROUND

Oropharyngeal dysphagia is prevalent among neurological patients, often necessitating enteral tube feeding with a nasogastric tube (NGT) or percutaneous endoscopic gastrostomy (PEG). These patients are at significant risk of developing aspiration pneumonia. This study aimed to assess the impact of oropharyngeal dysphagia on pneumonia risk requiring hospitalization in neurological patients on long-term enteral tube feeding.

METHODS

This retrospective observational study was conducted between 2015 and 2022. It included neurological patients who underwent upper gastrointestinal endoscopy combined with a Modified Flexible Endoscopic Evaluation of Swallowing (mFEES) for suspect dysphagia, characterized by difficulty or discomfort in swallowing. Participants were either orally fed or had been on long-term enteral tube feeding via NGT or PEG. A 2-year follow-up was conducted to monitor pneumonia cases requiring hospitalization. Multivariate analyses were conducted to identify risk factors for pneumonia requiring hospitalization.

KEY RESULTS

A total of 226 orally fed and 152 enteral tube-fed patients were enrolled. Multivariate analyses showed a significantly increased risk of pneumonia in patients with a history of pneumonia and those receiving enteral tube feeding. Subgroup analysis indicated a significantly lower risk of pneumonia among enteral tube-fed patients with oropharyngeal dysphagia who PEG-fed patients compared to NGT-fed patients (adjusted HR: 0.21, 95% CI: 0.10-0.44, p < 0.001). The cumulative incidence of pneumonia requiring hospitalization was significantly lower in the PEG group than in the NGT group (p < 0.001).

CONCLUSION

mFEES could be a screening tool for oropharyngeal dysphagia. PEG is preferred over NGT for long-term enteral feeding, as it significantly reduces the risk of pneumonia requiring hospitalization, especially in patients with oropharyngeal dysphagia.

Preoperative dysphagia and adverse postoperative outcomes in middle aged and older adults

BACKGROUND

Dysphagia is a swallowing impairment with adverse health consequences. The impact of preoperative dysphagia on postoperative outcomes is not known. This study will examine the association between preoperative dysphagia and postoperative outcomes.

METHODS

This is a retrospective, observational study of patients ≥50 years of age undergoing surgery not directly involving the swallowing mechanism (i.e., oral cavity, larynx, pharynx, or esophagus). The National COVID Cohort Collaborative (N3C) database from January 1st, 2020 to August 31st, 2023 was used. The N3C database comprises electronic health record (EHR) data from more than 75 US health systems and harmonizes these data in a centralized resource. The main predictor was dysphagia with or without malnutrition in the 3 months prior to surgery. Logistic regression models assessed the association between our main predictor and outcomes of mortality, readmission, and medical/surgical complications adjusted for covariates. A negative binomial regression model was used for length of stay (LOS).

RESULTS

380,869 adults ≥50 years old were included, mean age 66.0 (SD = 9.2), 52.6 % male. 7.9 % had dysphagia and/or malnutrition 3 months preoperatively including 3.0 % preoperative dysphagia alone, 3.8 % preoperative malnutrition alone, and 1.1 % both. Adjusted models demonstrated higher odds of mortality (1-year mortality odds ratio (OR) 1.37, 95 % confidence interval (CI) 1.29 to 1.44), readmission (90-day readmission OR 1.19, 95 % CI 1.14 to 1.24), and medical/surgical complications (OR 1.35, 95 % CI 1.28 to 1.42) among patients with 3 months preoperative dysphagia with or without malnutrition compared to patients with neither condition.

CONCLUSION

Patients with 3 months preoperative dysphagia with and without malnutrition had poor postoperative outcomes. These findings highlight the rationale for integrating dysphagia screening and intervention into routine preoperative protocols to mitigate the risk of adverse postoperative outcomes.

The Impact of Bolus Rheology on Physiological Swallowing Parameters Derived by Pharyngeal High-Resolution Manometry Impedance

BACKGROUND

The shear rheology of ingested fluids influences their pharyngo-esophageal transit during deglutition. Thus, swallowed fluids elicit differing physiological responses due to their shear-thinning profile.

METHODS

Two hydrocolloid fluids, xanthan gum (XG) and sodium carboxymethylcellulose gum (CMC), were compared in 10 healthy adults (mean age 39 years). Manometry swallowing assessments were performed using an 8-French catheter. Swallows were analyzed using the Swallow Gateway web application (www.swallowgateway.com). Grouped data were analyzed by a mixed statistical model. The coefficient of determination (r2) assessed the relationship between measures and bolus viscosity (SI units, mPa.s) at shear rates of 1-1000 s-1.

KEY RESULTS

Rheology confirmed that the thickened fluids had similar viscosities at 50 s-1 shear rate (XG IDDSI Level-1, 2, and 3 respectively, 74.3, 161.2, and 399.6 mPa.s vs. CMC Level-1, 2, and 3 respectively 78.0, 176.5, and 429.2 mPa.s). However, at 300 s-1 shear, CMC-thickened fluids exhibited approximately double the viscosity (XG Level-1, 2, and 3 respectively 19.5, 34.4, and 84.8 mPa.s vs. CMC Level-1, 2, and 3 respectively, 41.3, 80.8, and 160.2 mPa.s). In vivo swallows of CMC, when compared to XG, showed evidence of greater flow resistance, such as increased intrabolus pressure (p < 0.01) and UES Integrated Relaxation Pressure (UESIRP, p < 0.01) and shorter UES Relaxation Time (p < 0.05) and Bolus Presence Time (p < 0.001). The apparent fluid viscosity (mPa.s) correlated most significantly with increasing UESIRP (r2 0.69 at 50 s-1 and r2 0.97 at 300 s-1, p < 0.05).

CONCLUSION

Fluids with divergent shear viscosities demonstrated differences in pharyngeal function. These physiological responses were linked to the shear viscosity and not the IDDSI level.

Pathway analysis of the impact of dysphagia on the prognosis of patients with stroke: Based on structural equation modeling

BACKGROUND AND AIMS

Dysphagia is significantly correlated with prognostic outcomes in patients with stroke; however, the intrinsic mechanism of action between the two remains unclear. This study aimed to model the intrinsic mechanism of action between dysphagia and prognostic outcomes in patients with stroke based on structural equation modeling.

METHODS

A retrospective analysis of 900 inpatients with stroke from three large hospitals was performed. AMOS software (version 23.0) was used to construct the structural equation modeling.

RESULTS

The overall model showed a good fit (chi-square = 27.3, root mean square error of approximation = 0.01, standardized root mean square residual = 0.032, comparative fit index = 0.98, and adjusted goodness of fit = 0.94). Structural equation modeling showed that the total effect of dysphagia on the prognosis of patients with stroke was 0.694, with a direct effect of 0.599, accounting for 86.31 % of the total effect. The total indirect effect was 0.095, with the mediating effects of serum albumin level and pneumonia accounting for 6.48 % and 7.35 % of the total effect, respectively. The moderating effects of sex on dysphagia and the relationship between activities of daily living, modified Rankin scale score, and length of hospital stay were insignificant (ΔR2 = 0.063, P = 0.145; ΔR2 = 0.002, P = 0.620; ΔR2 = 0.001, P = 0.307).

CONCLUSIONS

Dysphagia can directly affect the prognostic outcomes of patients with stroke and indirectly affect prognosis by triggering pneumonia and lowering albumin levels. Sex was not found to play a moderating role in the relationship between dysphagia and prognosis.

Transoral Laser Microsurgery and Transoral Robotic Surgery in Aging Patients: A State-of-The-Art Review

Purpose

In the present study, the findings related to the epidemiology, clinical presentation, and therapeutic outcomes of elderly patients treated with transoral laser microsurgery (TOLM) and transoral robotic surgery (TORS) for supraglottic laryngeal squamous cell carcinoma (LSCC) have been reviewed.

Methods

A PubMed, Cochrane Library, and Scopus literature search was conducted according to the PRISMA statements. Critical literature analysis was carried out considering the last advancement in TOLS and TORS, and their related surgical, functional, and survival outcomes.

Findings

The mean age of patients with supraglottic LSCCs has progressively increased in the past decades. The data on postoperative complications in elderly patients with LSCC are heterogeneous and contradictory. The thought of the age-related high risk of complications was based on open supraglottic laryngectomy (SGL), but not on TOLM and TORS findings, which do not support an age-related increase of most postoperative complications. The only complication that could be associated with age is aspiration. The adequate selection of patients undergoing TOLM or TORS, and the pre- to postoperative evaluation of swallowing function can prevent this risk. The OS of elderly patients treated with TOLM or TORS SGL could be lower compared to younger patients. However, the disease-free survival was not influenced by age, highlighting the role of comorbidities and intercurrent diseases in the presumed lower survival. The survival analysis could definitively consider the physiological age rather than the chronological age to investigate the impact of age on survival outcomes.

Conclusion

The current literature supports an important place of TOLM and TORS in managing cT1-T3 supraglottic LSCC. The preoperative geriatric, nutritional, and swallowing evaluations are important for ensuring an adequate selection of patients treated with TORS or TOLM SGL.

Prevalence of Self-Reported Swallowing Difficulties and Swallowing-Related Quality of Life Among Community-Dwelling Older Adults in India

Self-reported swallowing difficulties are highly prevalent but underreported among older adults. The aging population in India is increasing, yet there is a lack of empirical data on self-reported swallowing difficulties in older adults. In the present study, we aimed to estimate the prevalence of self-reported swallowing difficulties and assess the swallowing-related quality of life (QOL) among community-dwelling older adults in India. We recruited 361 older adults (60-91 years) from the community. Participants completed the Eating Assessment Tool-10 (EAT-10) to assess self-reported swallowing difficulties and the Dysphagia Handicap Index (DHI) to assess swallowing-related QOL. Participants rated the EAT-10 from 0 for 'no problem' to 4 for 'severe problem'. The DHI rating included 0 for 'never', 2 for 'sometimes', and 4 for 'always'. The total scores of EAT-10 and DHI were summarised using descriptive statistics. Statistically significant differences between pass-fail groups of EAT-10 and DHI were evaluated using an independent t-test and multivariate analysis of variance test, respectively. The overall mean score for EAT-10 was 3.34, and 7.56 for DHI, with higher scores observed among females. 36.6% of older adults self-reported experiencing swallowing difficulties, while 47.4% self-reported having poor swallowing-related QOL at p < 0.05. A strong positive correlation (r = 0.86) was found between EAT-10 and total DHI scores at p < 0.001. The present study sheds light on the widespread yet underreported issue of self-reported swallowing difficulties and the impact on swallowing-related QOL among older adults in India. These findings emphasize the urgent need for early swallowing screening programs among older adults.

The Chinese version of the Ohkuma questionnaire: reliability analysis and diagnostic value

BACKGROUND

While the Ohkuma questionnaire is a simple, reliable, and easy-to-use tool to assess dysphagia, none of its versions can be used by the Chinese population.

OBJECTIVE

The purpose of this study was to evaluate the internal consistency, reliability and clinical validity of a newly made Chinese version of the Ohkuma questionnaire, and to provide some objective basis for its application in screening dysphagia.

MATERIALS AND METHODS

From September 21 to June 2022, 96 patients with dysphagia and 89 asymptomatic subjects were recruited from three hospitals in China to form an observation and a control group, respectively. All subjects completed the Ohkuma questionnaire, Eating Assessment Tool-10, and a Video Fluoroscopy Study of Swallowing.

RESULTS

The Cronbach's α coefficient measured in the questionnaire was 0.867, indicating acceptable internal reliability. The analysis of variance generated four main factors to be assessed, showing a good aggregation effectiveness of the questionnaire. The AVE square root values of three factors were greater than the maximum absolute value of the correlation coefficients between factors, indicating good differentiation effectiveness. The sensitivity and specificity scores, together with the positive and negative likelihood as well as diagnostic odds ratios indicate a good reactivity of the questionnaire. Lastly, after adjusting for age and sex, the results of the stepwise linear regression analysis showed that there was a significant positive correlation between the Ohkuma questionnaire and the penetration aspiration scale.

CONCLUSIONS

The Chinese version of the Ohkuma questionnaire has good reliability and validity, and can be used as a rapid and effective screening tool for dysphagia.

Dysphagia Screening in Brazilian Older Adults with Dementia: Content Development and Validation of a Questionnaire for Caregivers - RaDID-QC

This study aims to develop and validate the content and response processes of a questionnaire intended for caregivers to screen for dysphagia in Brazilian older adults with dementia due to Alzheimer's disease and/or vascular dementia. The instrument items were developed in Brazilian Portuguese language based on the theoretical framework. A committee of speech-language-hearing therapists analyzed the relevance, objectivity, clarity, and understandability of the items with the Delphi method. The content validity index cutoff agreement score for experts' answers to validate each item in the questionnaire was 0.78; in the intraclass correlation coefficient, it was 0.75 for all items. For response process validity evidence, the questionnaire was applied to 30 caregivers of older adults with dementia, who judged the clarity and understandability of the items. Each item was validated when understood by at least 95% of participants. The first version of the instrument had 29 items. After two expert assessments, the last version had 24 items. The intraclass correlation coefficient was 0.85. Only one item needed semantic adjustments in the pre-test. The dysphagia screening instrument applied to caregivers of older adults with dementia was developed with adequate content and response process validity evidence, enabling adjustments in its construct. Future studies will analyze the remaining evidence of validity and reliability.

Prevention of Aspiration: Oral Care, Antibiotics, Others

Patients with aspiration pneumonia often develop this lung infection due to poor oral health or because the contents of the digestive tract or upper airway enter the lower airway traversing the larynx through different mechanisms. Prevention of this condition is directed at the mechanism by which it occurs. The elderly are the most likely to suffer from aspiration pneumonia, occasionally due to issues related to poor dental health, but more frequently due to abnormal swallowing, which may appear after a stroke, a functional impairment related to aging, or may be part of a specific disease such as Parkinson's disease or some other nervous system condition. People with dysphagia complicated by pneumonia have limited feeding and become debilitated, and aspiration pneumonia in these individuals has a high mortality rate at 90 days. Dietary modifications, assistance with feeding, use of postures that facilitate a normal deglutition, rehabilitation, and use of medications to improve swallowing defects are the tools of medicine to overcome the obstacles to swallowing normally and prevent the development of aspiration pneumonia and its consequences.

Swallowing and Aspiration: How to Evaluate and Treat Swallowing Disorders Associated with Aspiration Pneumonia in Older Persons

Aspiration pneumonia (AP) is the most severe complication of oropharyngeal dysphagia (OD). It is highly underdiagnosed and undertreated among older patients hospitalized with community-acquired pneumonia (CAP). Our aim is to review the state of the art in the diagnosis and treatment of swallowing disorders associated with AP. We performed a narrative review, including our experience with prior studies at Hospital de Mataró, on the diagnosis and treatment of AP. AP refers to pneumonia occurring in patients with swallowing disorders, frequently coinciding with poor oral health and vulnerability. Its main risk factors include oropharyngeal aspiration, impaired health status, malnutrition, frailty, immune dysfunction, and oral colonization by respiratory pathogens. Incidence is estimated at between 5 and 15% of cases of CAP, but it is highly underdiagnosed. Diagnostic criteria for AP have not been standardized but should include its main pathophysiological element, oropharyngeal aspiration. Recently, a clinical algorithm was proposed, based on the recommendations of the Japanese Respiratory Society, that includes aspiration risk factors and clinical evaluation of OD. To facilitate the task for health care professionals, new artificial intelligence (AI)-based screening tools for OD combined with validated clinical methods such as the volume-viscosity swallowing test (V-VST) for the detection of AP are being validated. Prevention and treatment of AP require multimodal interventions aimed to cover the main risk factors: textural adaptation of fluids and diets to avoid oropharyngeal aspiration; nutritional support to avoid malnutrition; and oral hygiene to reduce oral bacterial load. The diagnosis of AP must be based on standardized criteria providing evidence on the main etiological factor, oropharyngeal aspiration. Clinical algorithms are valid in the diagnosis of AP and the identification of its main risk factors. Combination of AI-based tools with V-VST can lead to massive screening of OD and save resources and improve efficiency in the detection of AP.

Association between dysphagia and activities of daily living in older adults: a systematic review and meta-analysis

PURPOSE

Numerous epidemiological studies have suggested a possible association between dysphagia and the risk of decline in Activities of daily living (ADL) among older adults. This systematic review and meta-analysis aimed to elucidate the relationship between dysphagia and ADL in older adults.

METHODS

PubMed, Web of Science, Cochrane Library, Embase, Ebsco, MEDLINE, Wiley, CINAHL, and Ovid databases were comprehensively examined for relevant studies published up to October 31, 2022. Quantitative studies published in English were included to explore the relationship between dysphagia and ADL in people aged 65 years and older. The NIH Quality Assessment Tool was used to assess the study quality. R software was used to draw forest plots and I2 was employed to indicate study heterogeneity. Sensitivity analysis was performed using the one-by-one exclusion method. Publication bias was measured using funnel plots and Egger's test.

RESULTS

A total of 3,498 studies were retrieved from the database, 22 of which were eventually included in the systematic evaluation, and 14 of which were subjected to meta-analysis. Data from nine studies were categorical variables, and meta-analysis results showed that swallowing disorders in older adults were associated with a lower ability to perform ADL (OR = 3.39, 95% CI: 2.55-4.50, p < 0.001), with moderate heterogeneity (I2 = 62%, p = 0.006). Data from seven studies were continuous variables, resulting in a negative association between the prevalence of dysphagia and ADLs in older adults (SMD = -0.80, 95% CI: -1.08 to -0.51, p < 0.001), with high heterogeneity (I2 = 94%, p < 0.001). Sensitivity analysis showed robust results, funnel plots and Egger's test indicated no publication bias.

CONCLUSION

Dysphagia is significantly associated with the capacity to perform ADL. Prevention and screening of dysphagia in older patients dependent on others for daily care are needed. Further long-term studies are needed in the future to prove causality.

Impact of Modified Diet, Swallowing Exercises, and Neuromuscular Electrostimulation on Severity of Oropharyngeal Dysphagia of Geriatric Patients

Background and Objectives: Oropharyngeal dysphagia is a common swallowing disorder, characterized by difficulties in moving food and liquids from the mouth to the esophagus; it is particularly prevalent among older adults with neurological conditions. This study aimed to evaluate the effectiveness of a short-term complex treatment protocol combining dietary modifications, swallowing exercises, and transcutaneous neuromuscular electrostimulation in reducing the oropharyngeal dysphagia severity and aspiration risk among geriatric patients. Materials and Methods: A total of 64 participants aged 60 and older, with oropharyngeal dysphagia, at LSMU Kaunas Hospital between May 2021 and April 2023, were included in the study after excluding those with significant comorbidities. Diagnostic assessments included the water swallow test and Fiberoptic Endoscopic Evaluation of Swallowing, conducted before and after treatment. Results: The results indicated a statistically significant reduction in the severity of oropharyngeal dysphagia, with 18.8% of patients showing improvements from moderate to mild dysphagia and 33.3% from severe to moderate. Additionally, the median PAS score was four points (IQR 3-6) before treatment and significantly decreased to three points (IQR 2-4) after treatment (p < 0.001). Conclusions: These findings suggest that even a short-term multidisciplinary approach that lasts 10 days can effectively alleviate the symptoms of oropharyngeal dysphagia, enhance patient safety, and improve swallowing among geriatric patients suffering from this condition.

Association of oral health with nutritional status of the older adults: a cross-sectional study

OBJECTIVES

The potential association between oral health and nutritional status of the very old, has been poorly investigated. Thus, we carried out the cross-sectional study to evaluate the association of oral health with the nutritional status of the older adults.

METHODS

210 participants aged over 75 years were included in the study. Nutritional status was assessed by the Short-form Mini-Nutritional Assessment (MNA-SF) and body composition measurement. Data were available for self-reported oral health (10-item Eating Assessment Tool (EAT-10) and Chewing Function Questionnaire (CFQ)) and specific experimental tests including salivary flow, tongue and lip pressure, occlusal force, water swallow test and taste test for the detection of oral functions. Spearman rank correlation was used to analyze the correlation between body composition and oral health. Logistic regression and restricted cubic spline models were applied to examine the association of oral health with malnutrition.

RESULTS

The study reveals that poor oral health is related to the malnutrition. The tongue pressure and molar occlusal force were significantly associated with malnutrition in an L-shaped dose-response relationship after adjustment for potential confounding factors. The higher the tongue pressure and molar occlusal force, the lower the risk of malnutrition. Besides, the CFQ score, salty, sour, and bitter taste, are risk factors for malnutrition.

CONCLUSIONS

The presence of malnutrition is significantly associated with poor oral health in older adults. Our study supposes that the design of food suitable for oral conditions of the older adults may be another feasible solution to the nutritional problems among them.

Exploring mortality risk factors and specific causes of death within 30 days after hip fracture hospitalization

This study examined the sex-specific mortality risk and causes of death soon after hip fracture in Taiwan. The objective of this study was to evaluate the 30-day mortality risk and cause of death in patients with hip fracture and identify its associated risk factors. We conducted a retrospective cohort study using data from the National Health Insurance Research Database in Taiwan from 2000 to 2015. This study included patients aged 50 years or older who were admitted to a hospital with a hip fracture diagnosis for the first time. Of 285,891 patients hospitalized for their first hip fracture, 8,505 (2.98%) died within 30 days. The mortality risk of hip fracture declined from 3.76% in 2000 to 2.92% in 2015. Circulatory system diseases like ischemic heart disease and cerebrovascular disease were the most common cause of death and accounted for 22% of deaths within 30 days after fracture. Accidents and unintentional injuries caused 18% of deaths, followed by malignant neoplasms in 10% of deaths. Multivariate Cox regression identified older age, male sex, higher Charlson Comorbidity Index (CCI), suburban or rural residence, and lower income as risk factors for hip fracture mortality. The 30-day mortality risk of hip fractures has decreased but remains correlated with male sex, older age, and comorbidities. Circulatory diseases were the main cause of death. Early identification and treatment by experienced clinicians may optimize outcomes, minimize complications, and reduce mortality risk in the 30 days following hip fracture.

eTWST: An Extension to the Timed Water Swallow Test for Increased Dysphagia Screening Accuracy

We aimed to fine-tuning the Timed Water Swallow Test (TWST) screening procedure to provide the most reliable prediction of the Flexible Endoscopic Evaluation of Swallowing (FEES) assessment outcomes, with age, sex, and the presence of clinical signs of dysphagia being considered in the assessment. Participants were healthy people and patients with suspected dysphagia. TWST performance and participants' reported dysphagia symptoms were assessed in terms of their utility in predicting the outcome of a FEES assessment the same day. The FEES assessors were blinded to the nature of the TWST performance. The water swallowing capacity levels and clinical observations during a screening performance that were indicative of dysphagia/no symptoms in FEES were determined. Convergent validity was assessed as the agreement with the Functional Oral Intake Scale (FOIS) in the FEES assessment. TWST predicted FEES findings (aspiration and dysphagia) with a sensitivity of 72 and 45% and a specificity of 75% and 80%, respectively. Extended analysis of the TWST procedure (eTWST) identified aspiration (sensitivity = 92%, specificity = 62%) and dysphagia (sensitivity = 70%, and specificity = 72%) more accurately and showed a high correlation with FOIS (ɸ = 0.37). Excellent inter-rater reliability was further observed (Kw = 0.83). The extended evaluation of TWST performance has superior criterion validity to that of TWST. eTWST displayed high convergent validity and excellent interrater reliability. We therefore believe that eTWST can be highly relevant for clinical dysphagia screening.

Elderly patients with dysphagia in the intensive care unit: Association between malnutrition and delirium

BACKGROUND

Dysphagia, as a geriatric syndrome, is prevalent in the intensive care unit (ICU). Malnutrition resulting from swallowing disorders is likely to correlate with adverse ICU outcomes, including delirium, thereby escalating the costs of care and hospitalization. However, malnutrition has not received the attention it deserves in ICU clinical nursing practice. As two preventable and correctable conditions-malnutrition and delirium-the advantages of early identification and intervention are substantial. Exploring the relationship between malnutrition and delirium, starting from the high-risk group of elderly patients with swallowing difficulties in the ICU, will aid us in managing patients promptly and effectively.

AIM

To investigate the relationship between malnutrition and the incidence of delirium in elderly patients with dysphagia in the ICU.

STUDY DESIGN

This is a retrospective study. Data for this study were obtained from the Medical Information Mart for Intensive Care-IV. All 2273 patients included were dysphagia older patients over 65 years of age admitted to the ICU, and logistic regression was used to explore the relationship between malnutrition and delirium. We also used propensity score matching (PSM) for sensitivity analysis.

RESULTS

Among the included patients with swallowing difficulties, 13% individuals (297/2273) exhibited malnutrition, with a delirium incidence rate of 55.9% (166/297). In the non-malnutrition group (1976/2273), the delirium incidence rate is 35.6% (704/1976). After adjusting for 31 covariates, multifactorial logistic regression showed that malnutrition was significantly positively associated with the incidence of delirium in elderly dysphagic patients in the ICU (adjusted odds ratio (OR) = 1.96, 95% confidence interval (CI) = 1.47-2.62). The results remained stable after analysis by PSM.

CONCLUSION

Malnutrition was significantly positively associated with the incidence of delirium in elderly dysphagic patients in the ICU. Malnutrition should be given adequate attention in the ICU.

RELEVANCE TO CLINICAL PRACTICE

ICU nurses should pay particular attention to malnutrition, especially among the high-prevalence group of patients with dysphagia. Early identification and nutritional intervention for these patients may help reduce the costs of care and health care expenditures.

A survey of dysphagia services practice in China

BACKGROUND

Dysphagia services have only recently been formalised within Chinese health services. There has been no comprehensive evaluation of all aspects of dysphagia services practice in China.

AIMS

To provide a profile for the dysphagia practice in China by assessing various facets of dysphagia services.

METHODS AND PROCEDURES

This is a survey study carried out from December 2022 to May 2023 online in China. One hundred fifty-nine respondents comprising doctors, nurses or therapists involved in the field of dysphagia rehabilitation completed a questionnaire via Sojump. The questionnaire included dichotomous (e.g., yes/no) and multiple-choice questions related to participants' general information and their provision of dysphagia management services. Results were analysed descriptively and the differences among different levels of hospitals were analysed.

OUTCOMES AND RESULTS

Approximately two-thirds of hospitals (67.9%) started dysphagia services within the last 5 years. A significant difference in the initiation of dysphagia rehabilitation was observed across different hospital levels (χ2  = 32.70;p < 0.001). Routine dysphagia screening was a standard practice in most hospitals (71.7%), with the most frequently employed screening method being the water swallow test (95.6%). Clinical swallowing evaluation emerged as the preferred initial assessment method (80.5%) and the most utilised assessment method (91.8%). Video fluoroscopic swallow study and flexible endoscopic evaluation swallowing were used by 22.7% and 12.6% of respondents. A significant difference was observed in the choice of assessment methods across hospitals of different levels (χ2 = 43.397; p < 0.001). The majority of respondents (53.5%) primarily employed rehabilitation as the main intervention method (76%-100%). Most respondents indicated that they would reevaluate patients after treatment (74.8%) and reported routine follow-up with patients (60.4%).

CONCLUSIONS AND IMPLICATIONS

Despite the relatively recent development of dysphagia management in China, the practice patterns uncovered in this study are broadly consistent with Chinese guidelines and consensus. However, the use of instrumental assessments remains low, resulting in a lack of objective evaluation of patient conditions and outcomes. There is a need for policy and resource support in the field of dysphagia rehabilitation in China.

WHAT THIS PAPER ADDS

What is already known on this subject Assessment and treatment methods for dysphagia are various across different patients, medical facilities and settings. There has been no comprehensive evaluation of all aspects of dysphagia rehabilitation practice in China. What this study adds to existing knowledge The study assessed various facets of dysphagia rehabilitation in China through an online survey. We found that the relatively recent development of dysphagia management in China, but the practice patterns uncovered in this study are broadly consistent with Chinese guidelines and consensus. Variations in practice patterns between hospitals of different levels may be attributed to resource constraints and patient needs. Besides, while rehabilitation exercises are the primary intervention method for dysphagia in China, the assessment largely centres on clinical swallowing evaluation. The use of instrumental assessments remains low, resulting in a lack of objective evaluation of patient conditions and outcomes. What are the clinical implications of this work? The study assessed various facets of dysphagia rehabilitation in China, and the results indicate that the use of instrumental assessments needs to be improved and there is a need for policy and resource support in the field of dysphagia rehabilitation in China.

The Impact of Vocal Tremor on Deglutition: A Pilot Study

OBJECTIVE

Vocal tremor (VT) poses treatment challenges due to uncertain pathophysiology. VT is typically classified into two phenotypes: isolated vocal tremor (iVT) and essential tremor-related voice tremor (ETvt). The impact of phenotypes on upper aerodigestive tract physiology during swallowing remains unclear. Qualitative and quantitative measures were employed to characterize tremor phenotypes and investigate the effects on swallowing physiology.

METHODS

Eleven ETvt participants (1 Male, 10 Female; x̄ age = 74) and 8 iVT participants (1 Male, 7 Female; x̄ age = 71) swallowed 20 mL boluses in cued and uncued conditions under standardized fluoroscopic visualization. Sustained/a/productions were captured to assess the rate and extent of fundamental frequency (F0) modulation. Penetration and Aspiration Scale (PAS) scores were obtained and swallowing biomechanics were captured using Swallowtail™ software. Participants also completed the Swallowing Quality of Life (SWAL-QOL) questionnaire.

RESULTS

Hypopharyngeal transit was faster in both VT phenotypes compared with Swallowtail™ normative reference data. Total pharyngeal transit times, however, were only faster in patients with iVT, relative to reference data. No significant differences were observed on the SWAL-QOL or PAS between tremor phenotypes. SWAL-QOL scores revealed that these patients rarely reported dysphagia symptoms.

CONCLUSIONS

Subtle differences in swallowing patterns were observed across VT phenotypes, possibly related to adaptive mechanisms resulting in quicker pharyngeal bolus transit. Most patients did not report swallowing issues or dysphagia symptoms. This study is foundational for larger studies on this challenging population.

Oropharyngeal Dysphagia in Hospitalized Older Adults with Dementia: A Prospective Cohort Study

OBJECTIVE

Oropharyngeal dysphagia (dysphagia) is highly prevalent (up to 86%) in hospitalized patients with Alzheimer disease and related dementias (ADRD). This study aims to describe the management and clinical course of dysphagia in hospitalized patients with ADRD.

DESIGN

Prospective observational cohort study.

SETTING AND PARTICIPANTS

The study was conducted across 10 hospitals within a large health system in New York. Participants were older adults with ADRD admitted to the medicine service and diagnosed with dysphagia to liquids on speech-language pathologist (SLP) assessment and were recruited between January and June 2023.

METHODS

Baseline characteristics [eg, dementia Functional Assessment Staging Tool (FAST)], dysphagia management (eg, prescribed diet), and clinical course (eg, dysphagia improvement, respiratory complications) were collected.

RESULTS

Of patients with ADRD and dysphagia (n = 62), the average age was 86.5 and 66.1% were FAST Stage 7. On admission, 48.4% had pneumonia, 79.0% had delirium, and 69.4% were made nil per os (NPO) for aspiration risk. Of those who received SLP reassessment after diet initiation (n = 25), 76% demonstrated dysphagia improvement; 75% of patients with FAST stage 7 demonstrated improvement. Respiratory complications occurred in 21.0% of patients on the following diets: NPO, nasogastric tube feeding, dysphagia diets, and comfort feeds. In univariate analyses, hospital-acquired dehydration, no dysphagia improvement, and delirium were associated with respiratory complications.

CONCLUSIONS AND IMPLICATIONS

The potential for dysphagia improvement in hospitalized patients with ADRD (even those with advanced dementia) highlights the critical need for standardizing reassessment. Further studies are needed to evaluate factors associated with respiratory complications in this population.

Sarcopenia, dysphagia, and frailty in community-dwelling older adults: An analysis of mediation and moderated mediation models

Sarcopenia, dysphagia, and frailty are geriatric syndromes that commonly occur with age and are associated with various adverse health consequences. Nevertheless, the complex associations among them require further study to be clarified. The objectives of this study were to investigate (1) the potential role of dysphagia as a mediator in the association between sarcopenia and frailty and (2) the potential role of taste and smell dysfunction as a moderator of this mediator effect in community-dwelling older adults. A total of 352 older adults (mean age = 70.48 ± 5.31 years; 57.67% female) enrolled in this cross-sectional study. The SARC-F, Eating Assessment Tool-10 (EAT-10), and Edmonton Frailty Scale (EFS) were used to assess sarcopenia, dysphagia, and frailty, respectively. The Taste and Smell Dysfunction Questionnaire (TSDQ) was employed to assess taste and smell dysfunction. Frailty was present in 21.86%, sarcopenia risk in 39.77%, and dysphagia in 26.99% of the participants. The mediation analysis showed that the SARC-F had a significant effect on the EAT-10 (B = 1.001; p < 0.001), which in turn had a significant effect on the EFS (B = 0.129; p < 0.001). The direct (B = 0.659; p < 0.001), indirect (B = 0.129), and total (B = 0.778; p < 0.001) effects of SARC-F on EFS were significant. Of the association between sarcopenia and frailty, 16.6% was explained by dysphagia. The moderated mediation analysis showed that the TSDQ (B = 0.127; p < 0.001) moderated the association between SARC-F and EAT-10 and that the EAT-10 mediated the association between SARC-F and EFS only in older adults who scored moderate and high on the TSDQ (B = 0.049 and B = 0.114, respectively). The EAT-10 partially mediates the association between the SARC-F and the EFS, implying that sarcopenia affects frailty indirectly via dysphagia. Furthermore, taste and smell dysfunction moderates this mediator effect, with sarcopenia functioning as a mediator in older adults who scored moderate and high on the TSDQ. Therefore, it is plausible to anticipate that if someone has taste and smell dysfunction in addition to sarcopenia, they are more likely to have dysphagia and, ultimately, frailty. These findings emphasize the importance of addressing sarcopenia, taste and smell dysfunction, and dysphagia concurrently in frailty management in older adults.

Narrative review: nutritional strategies for ageing populations - focusing on dysphagia and geriatric nutritional needs

The increase in elderly populations worldwide highlights the urgency of addressing age-related problems through effective nutritional management to enhance the well-being of the elderly and for the prevention and treatment of various diseases. The trend towards an increasing elderly population brings with it an increase in conditions such as sarcopenia, osteosarcopenia and frailty, emphasising the importance of regular checks for malnutrition in the elderly and the implementation of personalised nutritional therapies. The importance of nutrition in addressing geriatric syndromes such as frailty, sarcopenia, osteosarcopenia, obesity and metabolic syndrome is highlighted. Dysphagia, frequent in the elderly, requires special attention to prevent malnutrition and complications. It is essential to maintain muscle mass and bone health in old age. In this review we investigate the fundamental role of nutrition in geriatrics, focusing on promoting healthy ageing and managing problems such as malnutrition and overeating. The importance of protein intake and healthy dietary patterns such as the Mediterranean diet are then discussed. Finally, the challenges of personalised nutritional care, including the need for artificial nutrition or oral supplements, to improve quality of life and health care in an ageing society are addressed.

Development and Validation of a Prediction Model for Dysphagia in Community-Dwelling Older Adults

Objectives. Dysphagia is a geriatric syndrome, which may lead to complications such as dehydration, malnutrition, aspiration, pneumonia, and a significant reduction in quality of life. The purpose of this study was to construct and validate a prediction model for dysphagia in community-dwelling older adults and provide an assessment tool for the prevention and control of dysphagia. Design. Cross-sectional study. Setting. The community-dwelling Chinese older adults. Participants. 3655 participants aged 65 years and older were involved, who were randomly divided into the training set and the validation set. Methods. Data were collected and analyzed from June 2022 to September 2022. Univariate and multivariate logistic regression analysis were used to identify independent risk factors for dysphagia. We applied R software to develop a nomogram model to predict dysphagia in community-dwelling older adults. The predictive value of the model was assessed by the area under the ROC curve (AUC), the calibration curve was used to evaluate the reliability of the nomogram model for predicting dysphagia in community-dwelling older adults. The model's clinical utility was further evaluated using a Decision Curve Analysis (DCA). Results. The incidence of dysphagia was 11.8% (320/3655). Maximum tongue pressure, number of molars, pneumonia, ADL, sarcopenia, age, neurological diseases, and rheumatic immune diseases were selected as risk predictors for dysphagia. The prediction model demonstrated fair discriminative ability with the AUC was 0.709 (95%CI: 0.679-0.739) in the training set and 0.693 (95%Cl: 0.640-0.747) in the validation set, the calibration is adequate, and the Hosmer and Lemeshow test showed p values of 0.163 and 0.415, respectively. The DCA curve of our model shows a positive clinical net benefit. Conclusions. The prediction model established in this study was of a certain predictive value for the risk of dysphagia in community-dwelling older adults. By estimating the likelihood of future outcomes or the onset of certain diseases, it can assist medical personnel in formulating preventive strategies, lessening the workload of nurses, and also diminishing the financial burden on patients, thereby enhancing their overall quality of life.

Prevalence of self-reported voice and swallowing complaints in an outpatient geriatric population

Background

Older adults suffer from increased rates of dysphagia and dysphonia, both of which have a profound effect on quality of life and are often underdiagnosed. We sought to better understand the prevalence of these complaints and the potential utility of a patient-reported screening program in a geriatrics clinic.

Methods

Using an IRB-approved cross-sectional survey and retrospective cohort design, we recruited participants from a population of new patients seeking care at an academic geriatrics clinic. We used three validated questionnaires to assess self-reported dysphagia, dysphonia, and pill dysphagia: the Eating-Assessment Tool-10 (EAT-10), the Voice Handicap Index-10 (VHI-10), and the PILL-5. Patients who screened positive on any questionnaire were offered referral to a laryngologist for additional evaluation. Patients who screened positive on the PILL-5 were also offered referral to our geriatric pharmacist.

Results

Among our 300 patients surveyed, the mean age was 76 (SD 8.46). A total of 82 (27.3%) patients screened positive (73 on EAT-10, 10 on PILL-5, 13 on VHI-10) and were offered referral, of which 36 accepted. These positive screening patients took more prescription medications (p = .024) and had a higher GDS score (p < .001) when compared to the patients who screened negative.

Conclusions

Many new patients seeking generalized care at our center screened positively for dysphagia and/or dysphonia on validated questionnaires. Geriatric patients may benefit from integrating screening for these disorders to identify the need of further evaluation. It is unknown if these survey tools are appropriate in a non-otolaryngology clinic.

Feeding Assistance Skill Score: development and verification of reliability and validity

PURPOSE

Feeding assistance should be safe and improve the assisted individual's ability to feed, yet objective tools for evaluating these skills are lacking. This study focuses on developing a tool for assessing feeding assistance skills.

METHODS

A group consisting of 25 experts employed the Delphi method to achieve a consensus on the essential items necessary for assessing feeding assistance skills. Subsequently, a draft score using a three-point scale was developed. To test the reliability of the draft scores, a group of 20 patients and 20 nurses was matched to record a meal assistance scene, which were independently evaluated by three raters. We computed the AC1 statistic to assess both intra- and inter-rater reliability, and further examined correlations between the Feeding Assistance Skill Score (FASS) scores and outcome items to verify validity.

RESULTS

Initially, an 18-item draft score was generated using the Delphi method. Subsequently, seven items were omitted from the intra- or inter-rater reliability analysis. Furthermore, after discussion, researchers removed one item that assessed food cognition, because the agreement score between the two items was 91%. Finally, the 10-item FASS was developed, showing a correlation with dietary intake upon validation.

CONCLUSIONS

We successfully developed a scoring system for peer evaluation of feeding assistance skills. Future studies should aim to validate the FASS. The implementation of the FASS aims to assess the effectiveness of feeding assistance training and care quality, potentially improving safety and satisfaction for those receiving feeding assistance.

Qualifications, professional roles and service practices of nurses, occupational therapists and speech-language pathologists in the management of adults with oropharyngeal dysphagia: a Nordic survey

PURPOSE

To identify the qualifications, professional roles and service practices of nurses, occupational therapists (OTs) and speech-language pathologists (SLPs) in the management of adults with oropharyngeal dysphagia (OD) in the Nordic countries.

METHODS

A web-based survey was developed that consisted of 50 questions on respondent demographics, education, experience, roles and service practices provided for adults with OD. The survey was distributed to practicing nurses, OTs, and SLPs in five Nordic countries via professional associations, social media, online networks and snowballing.

RESULTS

Data from 396 nurses, OTs and SLPs whom provided services for adults with OD revealed that the majority of respondents worked in acute care and inpatient rehabilitation facilities. Most respondents had minimal undergraduate education and practical clinical training in OD. Notable variances in roles and service practices in OD between professions and countries were found. OTs were the primary service provider for OD management in Denmark, while SLPs had this role in the other Nordic countries. Nurses were mainly involved in screening and some compensatory treatments in most Nordic countries. Limited use of evidence-based screening, non-instrumental or instrumental clinical assessments and rehabilitative therapeutic methods was evident.

CONCLUSIONS

Study results highlight challenges in education and training of professionals responsible for the management of adults with OD in the Nordic countries. Increased use of evidence-based assessment and exercise-based treatments to improve swallowing are warranted. Adherence to European and international clinical practice guidelines for the management of adults with OD is recommended.

sEMG as complementary tool for VFSS: A synchronized study in patients with neurogenic oropharyngeal dysphagia

The neurogenic oropharyngeal dysphagia is a prevalent functional swallowing disorder resulting from neurological causes. The conventional diagnosis involves ionizing radiation in Videofluoroscopy Swallowing Studies (VFSS). Surface electromyography (sEMG) offers a non-invasive alternative by recording muscle activity. This research compares bolus passage timing through anatomical structures using VFSS and sEMG-related activation times. Fifty confirmed oropharyngeal dysphagia patients underwent synchronized VFSS and sEMG, evaluating muscle groups during cracker and fluid ingestion. sEMG revealed activation patterns in masseters, suprahyoid, and infrahyoid muscles, occurring before bolus passage through the mandibular line and concluding near the upper esophageal sphincter complex. sEMG identified differences in dysphagia severity (EAT-10 score), age, and diagnosis, contrasting VFSS results. Results indicate potential complementarity between sEMG and VFSS for dysphagia screening, diagnosis, and monitoring.

Adaptation and Validation of the Sydney Swallow Questionnaire into Kannada (KSSQ)

Self-rating questionnaires are necessary to quantify the impairment and the impact of impairment on the quality of life, provided that these questionnaires are delivered in the patient's native language. There are no questionnaires to assess the symptom severity of oropharyngeal dysphagia in Kannada-speaking individuals. The Sydney Swallow Questionnaire (SSQ) is one such explicit tool to assess the symptoms of dysphagia, especially among patients with oropharyngeal dysphagia. The SSQ is a simple and easy-to-understand questionnaire. Therefore, the present study aimed to adapt and validate the SSQ in Kannada. English version of the SSQ was translated to Kannada and was administered to two groups of native Kannada-speaking participants - Group 1 included 53 participants (66.49 + 12.65 years) diagnosed with oropharyngeal dysphagia, and Group 2 included 53 age and gender-matched native Kannada speakers with normal swallowing ability with no history and symptoms of swallowing disorders. Cronbach's alpha was used to assess the test-retest reliability. Internal consistency was assessed using the split-half correlation. The concurrent validity of the Kannada version of SSQ (KSSQ) was measured by determining the correlation between the total scores of KSSQ and the Kannada version of Dysphagia Handicap Index (DHI). The discriminant validity was assessed by comparing the KSSQ scores between the participants of both groups. The results indicated that the KSSQ had excellent test-retest reliability, strong internal consistency, and good concurrent and discriminant validity. Therefore, it was inferred that the KSSQ is a valid and reliable tool for assessing the symptoms of dysphagia, especially among Kannada-speaking patients with oropharyngeal dysphagia.

Nutritional care in older adults: are we doing everything? An expert opinion review

Malnutrition is a prevalent, yet often underdiagnosed and undertreated, condition in older adults. It is characterized by weight loss and/or reduced muscle mass due to diminished caloric intake, inflammation, and/or disease burden. In return, malnutrition can lead to diminished skeletal muscle functionality and disability, among others. Malnutrition plays a crucial role in the pathogenesis of two prevalent geriatric syndromes, namely sarcopenia and frailty. The complex interplay between malnutrition, sarcopenia, and frailty significantly impacts the older population, leading to increased morbidity, mortality, hospitalization rates, quality-of-life, and healthcare costs. Given the prognostic significance of malnutrition in geriatric care, recent guidelines emphasized the role of nutritional support in vulnerable populations. A group of vulnerable populations to malnutrition, sarcopenia, and frailty are older patients with hip fractures, cancer patients, and those with sarcopenic dysphagia. This article highlights the importance of individualized nutritional assessment and treatment in the management of vulnerable populations such as older patients with hip fractures, cancer, and those suffering from sarcopenic dysphagia. It presents practical protocols and guidelines that can be instrumental in enhancing the nutritional care of these groups, thereby improving their overall health outcomes.

Food allergies in older people: An emerging health problem

The prevalence of food allergy (FA) is steadily increasing worldwide. Literature about FA in older people is very scarce since this is predominantly considered as a pediatric condition. However, FA can persist and/or develop across the life course. Given the growing increase in prevalence as well as their persistence, it can be expected that FA will soon represent an important issue in older people. Several age-related factors may potentially mask FA symptoms and/or mediate them in older people. These include mechanisms related to immune senescence, inflammation, and changes in gastrointestinal function as well as micronutrient deficiencies and the use of multiple medications. A multidimensional approach, taking into account the complexity in older people, it is thus important in the evaluation and management of FA during aging. The main and safest strategy in the management of FA is the allergen avoidance since their ingestion may lead to reactions ranging from mild to life-threatening. However, food restrictions should be carefully evaluated, especially in older people, for the risk of nutritional deficiencies and undernutrition.

Analysis of Patients' Dietary Status/Restrictions Following Instrumental Swallow Evaluations in Skilled Nursing Facilities

Many residents in Skilled Nursing Facilities (SNFs) present with dysphagia and receive altered diets or liquids to minimize the risk of complications. Limited access to timely instrumental evaluations of swallow may impede the best management of these dysphagic residents. De-identified FEES reports completed by a mobile FEES company during a single month, January 2019, were reviewed. Descriptive statistics were used to summarize the pre-study diet/liquid levels and the post-study diet/liquid recommendations. FEES reports (n = 952) were reviewed. Before the FEES evaluation, 209 residents were receiving only non-oral nutrition. After the FEES evaluation, 76% of these residents were recommended to receive oral nutrition. Before the FEES evaluation, 442 (46%) residents were receiving thickened liquids, after the FEES evaluation, 244 (26%) were recommended to have a less restrictive liquid level. Before the FEES evaluation, 576 (60%) residents were receiving altered food texture, after the FEES evaluation, 413 (43%) were recommended to have a less restrictive food texture. The percentage of residents recommended to receive thin liquids increased from 32 to 68% and those recommended to receive a regular diet increased from 18 to 34%. These data indicate that access to instrumental swallow evaluations in the SNF setting generally resulted in lifting liquid and diet restrictions for many residents in the cohort reviewed and potentially improved their quality of life.

Impact of Frailty on Post-Treatment Dysphagia in Patients with Head and Neck Cancer

In the rising and frail head and neck cancer (HNC) population, geriatric assessments are crucial. Frail HNC patients often experience dysphagia. The coexistence of dysphagia and frailty presents complex health challenges, however, there is limited evidence on the prognostic value of frailty on post-treatment dysphagia. This study explores the relationship between pre-treatment frailty status and post-treatment dysphagia in HNC patients. A retrospective data analysis from the OncoLifeS data-biobank at the University Medical Center Groningen of 242 patients diagnosed with HNC between 2014 and 2016. The study involved several physical, functional and psychological pre-treatment geriatric assessments, and frailty screening using the Groningen Frailty Indicator (GFI) and the Geriatric-8 screening tool (G8). Outcome measures were swallowing-related quality of life (HNSW-QoL) and toxicity-related dysphagia evaluations (CTCAE-D) at 3, 6, 12 and 24 months. Linear mixed-effects models assessed factors associated with HNSW-QoL and CTCAE-D. Frail patients consistently reported worse HNSW-QoL and CTCAE-D than non-frail patients over time, with symptoms increasing at 3 months, but gradually decreasing by 24 months. Frailty status (G8 or GFI) was a significant predictor for lower HNSW-QoL (β = 11.770 and 10.936, both p < 0.001), and lower CTCAE-D (β = 0.245, p = 0.058; β = 0.331, p = 0.019), respectively. In this study, frailty was found to be associated with a worse of swallowing-related quality of life, and with increased toxicity-related dysphagia. These findings provide insights for the identification of HNC patients at higher risk of post-treatment swallowing-related issues, and offer opportunities for optimizing their post-treatment swallowing outcomes.

Tackling unmanaged oropharyngeal dysphagia in primary care: a behavioural science realist review of interventions

INTRODUCTION

Oropharyngeal dysphagia (OD) is difficulty manipulating a food bolus from the mouth to the throat. Up to 70% of older adults develop OD; however, it is unmanaged in primary care, leading to avoidable hospitalisation.

OBJECTIVE

This behavioural science realist review aimed to develop programme theories to describe how interventions facilitate primary care healthcare professionals (HCPs) to proactively manage OD.

METHODS

We developed initial programme theories (IPTs) inductively using the expertise of stakeholders and deductively using the theoretical domains framework (TDF). Databases were searched to identify evidence regarding contexts, behavioural mechanisms and outcomes related to proactive management of OD and comparative behaviours which offer transferrable learning. IPTs were tested with the evidence to confirm, refine or refute, to produce final programme theories.

RESULTS

36 sources of evidence were included. Five final programme theories were generated explaining how primary care HCPs can be facilitated to proactively manage OD: (1) OD education and training, (2) checklists with OD signs and symptoms, (3) incorporating OD identification into existing workflow, (4) making HCPs aware that older adults and carers expect them to manage OD and (5) raising awareness of the adverse outcomes of OD.

CONCLUSION

The five programme theories provide the behavioural mechanisms by which an intervention may facilitate primary care HCPs to proactively manage OD. Through the programme theories' linkage to the TDF, behaviour change techniques (BCTs) mapped to the relevant TDF domain can be selected for an intervention. Operationalisation of selected BCTs into a coherent intervention package should be undertaken using codesign methodology.

The Effect of Thickened Water on Ciprofloxacin Pharmacokinetics: A Comparative Study in Adult Males

Background/Objectives: The use of food thickeners with ciprofloxacin tablets may result in a gelatinous appearance and experience delayed dissolution, which presents a challenge for the drug's efficacy, creating a healthcare economic issue. However, the pharmacokinetic impact of this compound in humans remains uncertain. Therefore, a comparative pharmacokinetic study of ciprofloxacin was conducted on healthy adult Japanese males. Methods: We compared the effects of administering tablets with water or thickened water and crushed tablets mixed with thickened water. The maximum blood concentration (Cmax) of ciprofloxacin determines the drug's efficacy. Results: There were variations in drug absorption across different administration methods. The group who took the tablets immersed in thickened water exhibited different results in the area under the blood drug concentration-time curve (AUC) and Cmax compared to the group who took the tablets in regular water. Notably, the group that consumed the crushed tablets mixed with thickened water demonstrated equivalent results for both AUC and Cmax. Conclusions: Administering crushed tablets in thickened water may yield pharmacokinetics comparable to those of tablets taken with water. However, the process of crushing tablets may result in the loss of active ingredients and compromise the formulation, necessitating a comprehensive assessment before administration.

Do Orally Disintegrating Tablets Facilitate Medical Adherence and Clinical Outcomes in Patients with Post-stroke Dysphagia?

Orally disintegrating tablets (ODTs) dissolve rapidly in contact with saliva and have been reported to facilitate oral administration of medications in swallowing difficulties. However, their clinical benefits remain unclear because no previous studies have examined whether ODTs facilitate medication adherence and clinical outcomes in patients with post-stroke dysphagia. This study evaluated the association between ODT prescriptions and clinical benefits using high-dimensional propensity score (hd-PS) matching to adjust for confounding factors. Using a large Japanese commercial medical and dental claims database, we identified patients aged ≥ 65 years with post-stroke dysphagia between April 2014 and March 2021. To compare 1-year outcomes of medication adherence, cardiovascular events, and aspiration pneumonia between patients taking ODTs and non-ODTs, we performed hd-PS matching. We identified 11,813 patients without ODTs and 3178 patients with ODTs. After hd-PS matching, 2246 pairs were generated. Medication adherence for 1 year, based on the proportion of days covered, was not significantly different between the non-ODT and ODT groups before (0.887 vs. 0.900, P = 0.999) and after hd-PS matching (0.889 vs. 0.902, P = 0.977). The proportion of cardiovascular events (0.898 vs. 0.893, P = 0.591) and aspiration pneumonia (0.380 vs. 0.372, P = 0.558) were also not significantly different between the groups. This study found no significant differences in medication adherence, cardiovascular diseases, or aspiration pneumonia between the non-ODT and ODT groups in patients with post-stroke dysphagia. Both groups achieved a proportion of days covered exceeding 80%. Clinicians may consider prescribing ODTs or non-ODTs based on patient preferences rather than solely on post-stroke conditions.

Dysphagia risk evaluated by the Eating Assessment Tool-10 is associated with health-related quality of life in patients with chronic liver disease

OBJECTIVE

This study aimed to reveal the prevalence and characteristics of individuals at risk of dysphagia in patients with chronic liver disease (CLD) and its association with health-related quality of life (HRQOL).

METHODS

This cross-sectional study included 335 outpatients with CLD. Dysphagia risk, sarcopenia risk, malnutrition risk, and HRQOL were assessed using the Eating Assessment tool-10 (EAT-10), SARC-F, Royal Free Hospital-Nutrition Prioritizing Tool (RFH-NPT), and Chronic Liver Disease Questionnaire (CLDQ), respectively. Dysphagia risk and low HRQOL were based on EAT-10 ≥3 and CLDQ overall score <5, respectively. Factors associated with dysphagia risk and low HRQOL were assessed using the logistic regression model.

RESULTS

Dysphagia risk and lower HRQOL were observed in 10% and 31% of the patients, respectively. Patients with dysphagia risk were older, had lower liver functional reserve, were at higher risk for sarcopenia and malnutrition, and showed lower CLDQ overall score (median, 4.41 vs. 5.69; P < 0.001) than those without. After adjustment, SARC-F (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.02-1.50; P = 0.029) and RFH-NPT (OR, 1.71; 95% CI, 1.04-2.81; P = 0.034) scores were independently associated with dysphagia risk. EAT-10 (OR, 1.17; 95% CI, 1.04-1.30; P = 0.008) and SARC-F (OR, 1.37; 95% CI, 1.18-1.59; P < 0.001) scores were also independently associated with low HRQOL.

CONCLUSIONS

Dysphagia risk was prevalent in approximately 10% of patients with CLD and was associated with a risk of sarcopenia and malnutrition. Furthermore, dysphagia risk was related to HRQOL in patients with CLD.

Summary of the best evidence for the management of dysphagia in elderly patients

OBJECTIVE

To search for and summarize the best evidence for themanagement of elderly patients with dysphagia.

METHODS

Clinical decisions, recommended practices, evidence summaries, clinical practice guidelines, expert consensus, and systematic reviews on the management of dysphagia among elderly patients were systematically reviewed from domestic and foreign guideline websites, association websites, and Chinese and English databases according to the 6S model of evidence-based resources. The search period was between January 1, 2010 and November 1, 2023. Two researchers evaluated the quality of the included literature respectively and extracted evidence.

RESULTS

A total of 14 literatures were identified, including 2 guidelines, 2 clinical decisions, 5 evidence summaries, 3 expert consensus statements, and 2 systematic reviews. Twenty-four pieces of evidence from 7 aspects were summarized, including assessment, treatment and rehabilitation, medication care, nutrition management, oral care, complication management, and psychological care.

CONCLUSION

The best evidence-based recommendations for the management of dysphagia in elderly patients is summarized, it is suggested that the best evidence should be selected according to the actual situation of patients, and a personalized management plan should be formulated to improve the quality of life of patients and achieve high-quality nursing.

Impact of Patient Factors on Attendance at Remote Telehealth Swallow Therapy

In-person swallow therapy is a primary and effective treatment for dysphagia. However, remote telehealth is now a widely utilized component of healthcare delivery for therapeutic interventions. This study evaluates potential factors influencing attendance at telehealth swallow therapy. Retrospective review of 308 patients referred for telehealth swallow therapy from April 2020-November 2021 included patient referral diagnosis, diagnostic swallowing evaluations, and sociodemographic information including age, race, health insurance, interpreter use, and socioeconomic status. Univariable and multivariable analyses compared patient and appointment factors for those who attended telehealth swallow therapy with those who did not attend. Overall, 71.8% of patients attended at least one telehealth swallow therapy appointment while 28.2% did not attend any. The most common referral diagnoses were "Cancer" (19.2%) and "Dysphagia Unspecified" (19.2%). Patients diagnosed with "Cancer" and "Muscle Tension" were significantly less likely to attend telehealth swallow therapy compared to those with "Dysphagia Unspecified," "Globus," and "Gastroesophageal Reflux Disease/Laryngopharyngeal Reflux" after adjusting for covariates. Lower socioeconomic status (p = 0.023), no interpreter use (p < 0.001), and more diagnostic evaluations (p = 0.001) correlated with higher telehealth swallow therapy attendance. Race and sex did not correlate with attendance. Most patients referred to telehealth swallow therapy attended at least one appointment. Patients with dysphagia associated with cancer and muscle tension, those with higher socioeconomic status, interpreter use, and fewer diagnostic swallowing evaluations were less likely to attend telehealth swallow therapy. Future research should investigate and compare attendance and efficacy of telehealth swallow therapy with in-person therapy.

Postextubation dysphagia management in Danish intensive care units: A national survey

BACKGROUND

Postextubation dysphagia (PED) is a common complication to endotracheal intubation in critically ill patients and may lead to pneumonia, prolonged ventilation, longer hospital stays, and increased mortality. Recognizing dysphagia is paramount to preventing adverse events. The aim of this study was to describe PED management by investigating practice in Danish intensive care units (ICUs) focusing on current practice in 2023 (screening, prevention, and treatment), perceived best practice (barriers and facilitators), and when possible, to compare practice in 2017 and 2023.

METHODS

Self-reported, cross-sectional survey of dysphagia practice in Danish ICUs administered from April to May 2023. In addition, data were compared with the 2017 Dysphagia in Intensive Care Evaluation study, when possible.

RESULTS

Only half of Danish ICUs reported to have a PED protocol, and less than half routinely screen patients for dysphagia after extubation. Most common screening methods were the oral mechanism examination, water test, and Facio-oral tract therapy. Nurses and physicians often relied on an overall physical assessment of the patient. Best treatment methods were uniformly agreed to be patient positioning, modification of food and fluids, use of ergonomic utensils, and compensatory maneuvers. Key barriers to dysphagia management were lack of specialized staff, under-recognition of dysphagia as a health issue, and lack of standardized protocols.

CONCLUSION

Awareness of PED is increasing and identification, prevention, and treatment is slowly improving, but systematic implementation of protocols for dysphagia screening and treatment could enhance dysphagia management in Danish ICUs.
