Impact of Modified Diet, Swallowing Exercises, and Electrostimulation on Quality of Life of Older Patients Suffering from Oropharyngeal Dysphagia.

Background and Objectives: Oropharyngeal dysphagia is defined as a swallowing disorder in which it becomes difficult to form a bolus and move food from the mouth to the proximal part of the esophagus. Several factors can cause this disorder in geriatric patients. With oropharyngeal dysphagia, the patient's social isolation and the risk of depression increase, while the quality of life deteriorates. Materials and Methods: In this study, oropharyngeal dysphagia was suspected based on the EAT-10 questionnaire and diagnosed with the water drink test and endoscopic swallowing evaluation, which assesses the aspiration risk by using an eight-point Penetration-Aspiration scale. Patients with oropharyngeal dysphagia received complex treatment: exercises to strengthen the swallowing muscles, electrostimulation of the swallowing muscles, and a modified diet. The quality of life of 64 patients was assessed by using the DHI, SWAL-QoL, and EAT-10 questionnaires before complex treatment and after treatment. The results show that the quality of life improved after the complex treatment of oropharyngeal dysphagia. Results: The mean age of patients was 77.8 (9.1) years, and 56.3% of patients were women. At baseline, mild oropharyngeal dysphagia was found in 18.8% of patients; moderate-in 51.6%; and severe-in 29.7%. Aspiration risk was low in 28.1% of patients; medium-in 39.1%; and high-in 32.8%. The severity of oropharyngeal dysphagia and aspiration risk significantly decreased after treatment (p = 0.002). The EAT-10 score mean was 15.23 (8.92) points before treatment and decreased to 11.50 (6.12) points after treatment (p < 0.001). Before treatment, the DHI physical score was 15.75 (6.813), the DHI functional score was 14.56 (8.659), and the DHI emotional score was 11.06 (7.848) (p < 0.001), and after complex treatment, the DHI physical score was 14.56 (8.659), the DHI functional score was 9.74 (7.165), and the DHI emotional score was 7.94 (6.588) (p < 0.001). The total SWAL-QoL score mean was 132.71 (34.392) points before treatment and increased to 152.42 (30.547) points after treatment (p < 0.001). Conclusions: Complex treatment of oropharyngeal dysphagia plays an important role in improving the quality of life and reducing aspiration risk in older people affected by this condition.

Clinical evaluation of a machine learning-based dysphagia risk prediction tool.

PURPOSE: The rise of digitization promotes the development of screening and decision support tools. We sought to validate the results from a machine learning based dysphagia risk prediction tool with clinical evaluation. METHODS: 149 inpatients in the ENT department were evaluated in real time by the risk prediction tool, as well as clinically over a 3-week period. Patients were classified by both as patients at risk/no risk. RESULTS: The AUROC, reflecting the discrimination capability of the algorithm, was 0.97. The accuracy achieved 92.6% given an excellent specificity as well as sensitivity of 98% and 82.4% resp. Higher age, as well as male sex and the diagnosis of oropharyngeal malignancies were found more often in patients at risk of dysphagia. CONCLUSION: The proposed dysphagia risk prediction tool proved to have an outstanding performance in discriminating risk from no risk patients in a prospective clinical setting. It is likely to be particularly useful in settings where there is a lower incidence of patients with dysphagia and less awareness among staff.

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.

The 100 ml-Timed Water Swallow Test: Pilot Data from Children with No Dysphagia.

Dysphagia screening tests are useful in identifying possible dysphagia for further evaluation and in supporting feeding recommendations. This study aimed to investigate swallowing parameters in children, while widening the pool of data available, using the '100 ml-Timed Water Swallow Test' (100 ml-TWST). Sixty Singaporean children aged 4 to 18 years old completed the 100 ml-TWST via a cup and a straw. Task completion, presence of cough, choke or throat clear, post-swallow voice quality, total time taken and number of swallows were observed. Subsequently, analysis of time per swallow (T/S), volume per swallow (V/S) and volume per time or swallowing capacity (V/T) were performed. Higher tendencies for coughing and task incompletion were observed in younger participants. A shorter time taken, fewer number of swallows, greater V/S and greater swallowing capacity were observed for adolescent or male participants, or via the mode of cup drinking. These could be due to oropharyngeal structural changes and swallow maturation with age, an increased capacity of oropharyngeal structures for swallowing in adolescent males, and more controlled or paced drinking from a straw. A plateau in time taken, number of swallows and swallowing capacity in adolescence were also observed, possibly indicating an emerging maturation of swallow functions during that period. Interestingly, speed of bolus movement was largely unaffected by age, gender and mode of drinking. Pilot data for children with no dysphagia have been established, while gaining insight into the swallowing parameters and maturation process in the paediatric population.

The Water Swallow Test and EAT-10 as Screening Tools for Referral to Videofluoroscopy.

BACKGROUND: Videofluoroscopy (VFS) is the gold standard in evaluating dysphagia. Water swallow tests (WST) and the Eating Assessment Tool (EAT-10) are commonly used in dysphagia screening. We aimed to determine the feasibility of WST and EAT-10 as screening tools for referral to VFS. METHODS: Patients (n = 150, median age: 70.0 years, range: 19-92 years, 58.7% female) referred to VFS completed the WST and EAT-10 before the examination. In the WST, we evaluated both the qualitative parameters (coughing, possible change in voice) and quantitative parameters (average drinking bolus size, swallowing speed). Correlations of EAT-10 total scores and WST parameters to the VFS findings were analyzed both individually and combined. RESULTS: In the WST, the most specific (89.7%) predictor of normal VFS findings was the absence of coughing, and the most sensitive (79.1%) parameter to predict abnormal findings was a bolus size of ≤20 mL. Using a combination of coughing and a bolus size ≤20 mL (simplified WST), the sensitivity of predicting abnormal findings increased to 83.5%. The most sensitive (84.6%) predictor of penetration/aspiration was failing any parameter in the WST. Lack of coughing indicated an absence of penetration/aspiration with an 82.5% specificity. Swallowing speed or combining the EAT-10 results with the WST results did not enhance the sensitivity or specificity of the WST for predicting the VFS results. CONCLUSIONS: Coughing and average drinking bolus size are the most important parameters in WST when screening for referral to VFS, whereas the swallowing speed does not seem to be useful. The WST is superior to EAT-10 in predicting VFS findings. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1349-1355, 2024.

Aspiration Risk Screening With Tongue Pressure Measurement in Acute Stroke: A Diagnostic Accuracy Study Using STARD Guidelines.

Introduction: Dysphagia can affect more than 50% of stroke patients in the acute phase. Aspiration pneumonia is a serious complication that can be prevented with dysphagia screening and assessment. Measurement of tongue elevation pressure is suggested to be a useful tool in aspiration risk screening. Objective: This study aimed to assess the diagnostic accuracy of maximum anterior tongue elevation strength (Pmax) in acute stroke care. Method: In this prospective study, data were collected in a neurology department (stroke center) where patients formed a consecutive case series. The sample consisted of thirty stroke patients who failed an initial dysphagia screening. Patients underwent anterior tongue elevation strength measurement (index test) during bedside dysphagia assessment by a speech-language pathologist and flexible endoscopic evaluation of swallowing (reference test) by an otorhinolaryngologist on the same day. Outcome variables (index values in kPa, reference values interpreted on the penetration-aspiration scale) were used for estimating measures of diagnostic accuracy in aspiration risk screening. Results: Ten patients aspirated on instrumental evaluation. At the cut-off point of ≤ 34 kPa the analysis showed 90% sensitivity, 35% specificity, 41% positive predictive value, and 88% negative predictive value. The area under the curve (AUC) for Pmax was AUC = 0.700 (95% CI [0.500-0.900]). Conclusion: Although individuals with low anterior tongue elevation strength tend to have a higher risk of aspiration, this variable alone is not capable of screening aspiration in acute stroke. In combination with a thorough noninstrumental bedside examination, it might have the potential to reduce the number of false positive cases. Further studies in this area would be worthwhile.

Adaptation and Validation of the Standardized Swallowing Assessment Tool for Patients With Moderate-Severe Traumatic Brain Injury and Cervical Spinal Cord Injury.

Oropharyngeal dysphagia is common in moderate-severe traumatic brain injury (TBI) and cervical spinal cord injury (SCI) patients and can have serious consequences. Delaying feeding in these patients can also be detrimental. Nonetheless, the psychometric properties of screening tools that can promptly identify dysphagia have never been tested in these neurotrauma populations. This study aimed to: (1) adapt, translate, and validate the content of the French-Canadian version of the the Standardized Swallowing Assessment (SSA) tool to meet the needs of moderate-severe TBI and cervical SCI patients, (2) examine its inter-rater reliability and criterion-concurrent validation, and (3) evaluate its clinical utility from the perspectives of critical care nurses. The SSA tool was adapted and translated using an integrated method for the cultural adaptation and translation of tools. Eleven experts participated in the adaptation of the SSA tool, which led to the clarification of one item, as well as a new step and instructions for the screening procedure. Content validation (i.e., item and scale relevance) was evaluated by multidisciplinary team members (n = 17). The mean content validity index (CVI) score was 0.97 for the entire scale, while the mean CVI scores for individual items ranged from 0.82 to 1.0. A total of 60 neurotrauma patients were enrolled for inter-rater reliability and criterion-concurrent validation. Interrater reliability was determined by comparing two scores: one score from nurses responsible for the care of enrolled patients and one score from the research nurse. The weighted kappa coefficients for inter-rater reliability were 0.86 for moderate-severe TBI patients (n = 30) and 0.73 for cervical SCI patients (n = 30). A speech language therapist (SLT) also assessed dysphagia and results were used as the standard clinical reference criterion to determine concurrent validity (sensibility and specificity) of the adapted SSA tool. The sensitivity and specificity were 92% and 50% for moderate-severe TBI, and 77% and 75% for cervical SCI, respectively. The positive predictive value (PPV) and the negative predictive value (NPV) were 65% and 87% in TBI patients, and 75% and 76% in SCI patients. Test accuracy was 71% and 77% for these same groups. The clinical utility of the tool was evaluated according to the following domains: appropriateness, accessibility of the required material, applicability, perceived effectiveness, and acceptability. Acceptability was the only domain with a level of agreement <80% (74%) among trauma critical care nurses (n = 49). Findings support the content validation and inter-rater reliability of the adapted French-Canadian version of the SSA tool in moderate-severe TBI and cervical SCI patients. Sensitivity was acceptable in both groups, but the specificity was lower, especially in moderate-severe TBI patients. Further validation of the adapted French-Canadian version of the SSA tool is needed in neurotrauma patients to confirm these results and to ensure safe dysphagia screening while avoiding oral feeding deferrals.

Consistencies among miscellaneous scales for evaluation of post-stroke dysphagia.

PURPOSE: Post-stroke dysphagia (PSD) is the most common type of dysphagia. Stroke patients with sustained dysphagia have poorer outcomes. The severity of PSD is assessed using miscellaneous scales with unknown consistencies. We aim to investigate the consistencies among miscellaneous scales, which could aid in the assessment of PSD. METHODS: A total of 49 PSD patients were enrolled. Functional Oral Intake Scale (FOIS), Dysphagia Severity Scale (DSS), Ohkuma Questionnaire, Eating Assessment Tool-10, and Repetitive Saliva Swallowing Test were performed. FOIS was performed by physicians, and DSS was conducted by both the physicians and nurses; the physicians used either videofluoroscopy (VF) or videoendoscopy (VE) for evaluation; while, the nurses assessed PSD by observation and subjective judgment. RESULTS: When using VF (VF-DSS and VF-FOIS) as the gold standard for the evaluation, VE-FOIS (κ = 0.625, 95% CI 0.300-0.950, p < 0.001) has a substantial agreement with VF-FOIS, and VE-DSS (κ = 0.381, 95% CI 0.127-0.636, p = 0.007) has a fair agreement with VF-DSS. The weighted kappa of FOIS to DSS in VE (weighted κ = 0.577, 95% CI 0.414-0.740, p < 0.001) is not lower than that in VF (weighted kappa = 0.249, 95% CI 0.136-0.362, p < 0.001). CONCLUSION: For both DSS and FOIS, only VE has a statistically significant agreement with VF. Though VF has been viewed as the traditional gold standard of dysphagia screening, it has the limitations of being invasive and equipment dependent. For PSD, VE could be considered as a substitution when VF is not available or suitable.

[Diagnostics and treatment of post-stroke dysphagia]. / Diagnostik und Therapie der Dysphagie nach einem Schlaganfall.

BACKGROUND: Post-stroke dysphagia is highly prevalent and leads to severe complications, such as aspiration pneumonia and malnutrition. Despite the high clinical relevance dysphagia management is heterogeneous and often inadequate. OBJECTIVE: The aim of this review article is to provide an overview of the diagnostic and treatment strategies for post-stroke dysphagia based on recent studies. MATERIAL AND METHODS: Narrative literature review. RESULTS: Dysphagia screening should be performed as early as possible in every stroke patient, e.g., with a simple water swallowing test or a multiconsistency protocol. Subsequently, flexible endoscopic evaluation of swallowing (FEES) is indicated in patients with abnormal screening results or existing risk factors for dysphagia. Dietary modifications, oral hygiene measures, and nutritional therapy can help reduce complications. Behavioral swallowing therapy or experimental therapies, such as neurostimulation procedures and pharmacological approaches aim to improve swallowing function and have shown promising results in studies. CONCLUSION: Timely management of dysphagia is necessary to reduce complications.

A Within-Subject Comparison of Face-to-Face and Telemedicine Screening Using the Timed Water Swallow Test (TWST) and the Test of Mastication and Swallowing of Solids (TOMASS).

The Timed Water Swallow Test (TWST) and the Test of Mastication of Solids (TOMASS) are dysphagia screening procedures that have been shown to be reliably assessed from video. The reliability of the procedures performed over telemedicine has not previously been assessed. TWST and TOMASS outcomes in two situations (both face-to-face and over telemedicine) were compared for 48 participants (aged 60-90; 27 with clinical conditions and 21 older persons). Both testing situation and test performed order were randomized, and all assessment procedures were performed within 3 h of each other. The results indicated a high level of agreement between face-to-face and telemedicine screening outcomes for TWST and TOMASS, respectively. The assessments indicated an 83% and 76% agreement in classifications of individual participants as within or outside normal limits for the TWST and TOMASS for the two test situations. The TWST showed a balanced distribution in differing classification in telemedicine (0.16-0.19 error rates). The TOMASS procedure classified more participants as outside normal limits over telemedicine compared to face-to-face administration. Agreement in the observed number of swallows was substantially lower than other outcome measures, which is attributed to increased difficulty in observing this property over video. Most participants (60%) reported that they would prefer telemedicine over face-to-face assessments, and 90% viewed the procedure as more accessible than expected. All participants were satisfied with the telemedicine procedures. The results suggest that clinical assessment of dysphagia over telemedicine using the TWST and TOMASS are viable alternatives to face-to-face administration of the procedures.

Utility of modified Mann assessment of swallowing ability (MMASA) in predicting aspiration risk and safe swallow in stroke patients.

Introduction: Aspiration pneumonia is one of the commonest causes of post-stroke mortality. We may be able to reduce this morbidity and mortality by assessing the risk of aspiration in stroke patients. Assessment of this risk can be done using a physician-administered screening protocol to assess dysphagia. A score of ≥95 is a good cut off to detect patients who can take oral feeds safely. Objectives: The primary objective was to predict aspiration risk using the Modified Mann Assessment Swallowing Ability (mMASA) scale. The secondary objective was to predict the safety of oral feeds using the same scale. Materials and Methods: An analytical cross-sectional study was conducted at a tertiary care rehabilitation centre in South India. A total of 100 stroke patients who underwent stroke rehabilitation in the study institution were divided into patients who were able to eat orally or not based on the mMASA scale. Demographic and stroke characteristics were recorded. The mMASA score was calculated and those with a score of ≥95 were given oral feeds. Those who scored <95 were given swallow therapy and re-evaluated in 2 weeks. Also, the mMASA score below which the patient was likely to develop aspiration pneumonia was detected using the receiver operating characteristic curve (ROC). Results: Out of the 100 patients, 37 patients had a score of ≥95 and were started on oral feeds and had no complications; the rest were started on 2 weeks of swallow therapy. On re-evaluation after swallow therapy, 12 more were started on oral feeds. The remaining 51 patients did not reach the cut-off score of ≥95 and were continued on nasogastric tube feeding. A total of 11 patients developed features of aspiration pneumonia; all of them belonged to the group of 51 patients who consistently had a mMASA score <95. The ROC curve determined that a score of <89 was a good cut off to predict patients who are at high risk of aspiration. Conclusion: The scale can be used to predict the likelihood of aspiration and readiness to start oral feeds in sub-acute stroke patients.

Dysphagia Management and Outcomes in Elderly Stroke Patients with Malnutrition Risk: Results from Chinese Stroke Center Alliance.

Purpose: To investigate the effectiveness of dysphagia screening and subsequent swallowing rehabilitation in elderly stroke patients with malnutrition risk. Patients and Methods: Based on the Chinese Stroke Center Alliance (CSCA) from August 1, 2015 to July 21, 2019, we compared the in-hospital adverse outcomes among stroke patients (including ischemic stroke, intracranial hemorrhage, and subarachnoid hemorrhage) over 70 years old with and without dysphagia screening. The primary outcome was in-hospital all-cause mortality. Secondary outcomes were the composite endpoint of discharge against medical advice (DAMA) or in-hospital death. Results: Among 365,530 stroke patients ≥ 70 years old with malnutrition risk in the CSCA, documented dysphagia screening was performed for 288,764 (79.0%) participants. Of these, 41,482 (14.37%) patients had dysphagia, and 33,548 (80.87%) patients received swallowing rehabilitation. A total of 1,694 (0.46%) patients experienced in-hospital death. After adjustment for traditional risk factors, dysphagia screening was associated with a low risk of all-cause mortality in stroke patients [adjusted odds ratio (aOR): 0.75, 95% confidence interval (CI):0.65-0.87]. Compared to patients with dysphagia who did not receive swallowing rehabilitation, patients reveiving swallowing rehabilitation had a reduced risk of in-hospital death (aOR:0.39, 95% CI: 0.33-0.46). Additionally, dysphagia screening had a lower risk for the composite endpoint of DAMA or in-hospital death (aOR:0.83,95% CI: 0.80-0.87), as did subsequent swallowing rehabilitation (aOR:0.43,95% CI: 0.40-0.47). Similar results were observed in the sensitivity analysis through inverse probability of treatment weighting, propensity score matching, and excluding patients without National Institutes of Health Stroke Scale scores. A similar association was observed between dysphagia management and adverse clinical outcomes in ischemic stroke and intracranial hemorrhage patients. Conclusion: Dysphagia screening and swallowing rehabilitation were associated with a reduced risk of in-hospital death and composite outcome of DAMA or in-hospital death for stroke patients with malnutrition risk. Future research should concentrate on improving the quality of medical care for dysphagia management to improve patients' outcomes.

Finnish Version of the Eating Assessment Tool (F-EAT-10): A Valid and Reliable Patient-reported Outcome Measure for Dysphagia Evaluation.

Our aim was to validate a Finnish version of the Eating Assessment Tool (F-EAT-10) for clinical use and to test its reliability and validity in a multicenter nationwide study. Normative data were acquired from 180 non-dysphagic participants (median age 57.0 years, 62.2% female). Dysphagia patients (n = 117, median age 69.7 years, 53.0% female) referred to fiberoptic endoscopic evaluation of swallowing (FEES) completed F-EAT-10 before the examination and after 2 weeks. Patients underwent the 100-ml water swallow test (WST) and FEES was evaluated using the following three scales: the Yale Pharyngeal Residue Severity Rating Scale, Penetration-Aspiration Scale, and the Dysphagia Outcome Severity Scale. An operative cohort of 19 patients (median age 75.8 years, 57.9% female) underwent an endoscopic operation on Zenker's diverticulum, tight cricopharyngeal muscle diagnosed in videofluorography, or both. Patients completed the F-EAT-10 preoperatively and 3 months postoperatively. The cut-off score for controls was < 3 (sensitivity 94.0%, specificity 96.1%) suggesting that ≥ 3 is abnormal. Re-questionnaires for test-retest reliability analysis were available from 92 FEES patients and 123 controls. The intraclass correlation coefficient was excellent for the total F-EAT-10 score (0.93, 95% confidence interval 0.91-0.95). Pearson correlation coefficients were strong (p < 0.001) for each of the questions and the total score. Internal consistency as assessed by Cronbach's alpha was excellent (0.95). Some correlations between findings in FEES and 100-ml WST with F-EAT-10 were observed. The change in subjective symptoms of operative patients paralleled the change in F-EAT-10. F-EAT-10 is a reliable, valid, and symptom-specific patient-reported outcome measure for assessing dysphagia among Finnish speakers.

Nurses' knowledge of stroke-related oropharyngeal dysphagia in the Eastern Cape, South Africa.

BACKGROUND: Early identification of stroke-related oropharyngeal dysphagia (OPD) using screening by nurses can prevent adverse patient outcomes in lower middle-income countries. Nurses are essential in the OPD management team and should ideally be able to screen and prioritise dysphagia management in stroke patients. OBJECTIVE: The aim of this research was to describe nurses' practices related to identification and management of patients with stroke-related OPD. METHODS: Qualified nurses from various healthcare levels in the Eastern Cape, South Africa were invited to complete a previously published hard copy survey on the signs and symptoms, complications and management of stroke-related OPD. A sample of 130 participants completed the survey. RESULTS: The mean scores of correct responses for each section were: 8.7/13 (66.7%) for signs and symptoms, 4.7/10 (47.3%) for complications and 3.8/7 (54.2%) for management practices. Statistically, there were no differences between the levels of healthcare for the signs and symptoms section and the complications section. Regarding management of OPD, secondary-level (S) nurses demonstrated significantly better knowledge than primary-level (P) and tertiary-level (T) nurses (S-P: p = 0.022; S-T: p = 0.010). Secondary-level nurses also scored significantly higher across all three sections (S-P: p = 0.044; S-T: p = 0.025) than those at the other levels. CONCLUSIONS: The study found that nurses across all levels of healthcare had only moderate knowledge regarding identification and management of stroke-related OPD. Interdisciplinary collaboration between nurses and speech-language therapists may improve nurses' knowledge in identification and management of stroke-related OPD in lower middle-income settings such as South Africa.

Implementing a flexible endoscopic evaluation of swallowing at elderly care facilities to reveal characteristics of elderly subjects who screened positive for a swallowing disorder.

OBJECTIVES: The risk of aspiration pneumonia has been reported to increase with age, especially in elderly residents of nursing homes. However, the characteristics of those with swallowing impairments at elderly care facilities have not yet been evaluated using reliable instrumental examinations. The aims of the current study were to investigate the frequency of swallowing impairment and determine the characteristics of the elderly with swallowing disorders residing at care facilities. METHODS: To reveal the characteristics of the elderly with swallowing disorders, questionnaires for dysphagia screening and flexible endoscopic evaluation of swallowing (FEES) were used. Regarding the dysphagia screening, two types of questionnaires were sent to 451 elderly persons aged 65 years and older who were living in facilities for the elderly in Japan. FEES was performed to assess swallowing impairment at each facility for those who were found to be positive for dysphagia by the questionnaires. The frequency of swallowing impairment and the characteristics of elderly subjects with swallowing disorders were investigated. RESULTS: Among 413 subjects who completed both questionnaires, 229 were screened positive for dysphagia, 160 of whom underwent FEES. Swallowing impairment was observed in 93 subjects. The subjects with swallowing impairment had a significantly high prevalence of fever, sputum, and/or history of aspiration pneumonia. Their oral intake ability and activities of daily living were significantly low. CONCLUSION: We demonstrated the frequency of swallowing disorders and the characteristics of elderly subjects with swallowing disorders living in care facilities using FEES. Our results suggest the importance of screening all elderly care facility residents for dysphagia.

Assessment of Aspiration Risk Using the Mann Assessment of Swallowing Ability in Brain-Injured Patients With Cognitive Impairment.

Objectives: The purposes of this study are to determine whether there is a correlation between the Mann Assessment of Swallowing Ability (MASA) and modified MASA (mMASA) according to various cognitive status and to investigate whether the cognitive status of patients with brain damage affects the prediction of aspiration using the MASA. Methods: We retrospectively assessed 146 dysphagic patients with brain lesion due to various causes. Dysphagia was assessed using the MASA and mMASA. According to the videofluoroscopic swallowing study results, patients were divided into two groups: aspirators and non-aspirators. Patients were classified into four groups according to cognitive function according to the Korean version of Mini-mental State Examination scores: normal (>24), mild (21-24), moderate (10-20), and severe (<10) cognitive impairment. The correlation between the MASA and mMASA scores according to cognitive function were analyzed. The sensitivity, specificity, and positive and negative predictive values of the MASA scores for predicting aspiration were assessed. Results: The MASA and mMASA scores showed a significant positive correlation in all cognition groups. In patients with more severe cognitive impairment MASA scores had high sensitivity and low specificity for prediction of aspiration. On the other hand, the MASA scores had low sensitivity and high specificity for prediction of aspiration in the normal and mild cognitive impairment groups. Conclusions: The MASA and mMASA scores correlated with each other in patients with various levels of cognitive function. Interestingly, this study results demonstrated that patients with good cognitive function may have false negative results of MASA screening due to low sensitivity. Thus, when interpreting the MASA results, the impact of cognitive status should be taken into consideration.

Does the Hebrew Eating Assessment Tool-10 Correlate with Pharyngeal Residue, Penetration and Aspiration on Fiberoptic Endoscopic Examination of Swallowing?

The Eating Assessment Tool-10 (EAT-10) is a 10-item patient-reported outcome measure (PROM) for dysphagia patients. The objective of this study was to translate and validate the EAT-10Heb and to test for a correlation between its score and residue, penetration and aspiration on Fiberoptic Endoscopic Examination of Swallowing (FEES). 136 patients visiting two specialized dysphagia clinics and undergoing FEES between April 2015 and August 2017, filled the EAT-10Heb. 23 patients refilled the EAT-10Heb during a 2-week period following their first visit. FEES were scored for residue (1 point per consistency, maximum 3 points) and penetration and aspiration (1 point for penetration, 2 points for aspiration per consistency, maximum 6 points). 51 healthy volunteers also filled the EAT-10Heb. Internal consistency and test-retest reproducibility were examined for reliability testing. Validity was established by comparing EAT-10Heb scores of dysphagia patients to healthy controls. The EAT-10Heb score was then correlated with the FEES score. Internal consistency of the EAT-10Heb was high (Cronbach's alpha = 0.925) as was the test-retest reproducibility (Spearman's correlation coefficient = 0.82, p < 0.0001). The median EAT-10Heb score was significantly higher in the dysphagia group compared to healthy controls (13, IQR 7-22 points for dysphagia patients compared to 0, IQR 0-0 points for healthy controls, p < 0.0001). A weak correlation was found between the EAT-10Heb scores and the FEES score (Pearson's correlation coefficient = 0.376, p < 0.0001). While the EAT-10Heb was found to be a reliable and valid PROM, it only weakly correlates with the pathological findings on FEES examination.

Registered Nurse's Competency To Screen Dysphagia Among Stroke Patients: Literature Review.

BACKGROUND: An increased number of elderly people in the world may lead to an increase in the incidence of stroke, which creates a burden on the country's healthcare system. Dysphagia is the most common post stroke. Screening of dysphagia in stroke patients is serious to prevent complication linked to aspiration and inadequate hydration/nutrition. OBJECTIVE: This literature review aimed to discuss registered nurses' competency to screen dysphagia among stroke patients. METHODS: The keywords used were nurse's competency; dysphagia; dysphagia screening; and stroke. These keywords were entered into multiple electronic databases including CINAHL, Medline, Science Direct, Pro Quest, Pub Med, and Wiley Online Library. Aliterature search was conducted for the period2005 to 2016.Results:Seventeen studies were identified by a systematic search ofthe literature.Two parts created the body of this literature review. The first part covers the literature on the training nurses in screening dysphagia among stroke patients and benefits of screening. The second part covers nurse's competency in terms of knowledge and skills of screening dysphagia among stroke patients. CONCLUSION: Because the nurses have more contact with the patient, they are most likely to observe dysphagia. It is important that formal dysphagia screening protocols are routine nursing care that requires special training to practice. Trained nurses should assess their competency in terms of knowledge and skills via well-developed tool.

Predicting Dysphagia with National Institute of Health Stroke Scale: Distinction between Infra- and Supratentorial Region is Essential.

BACKGROUND: For the early detection of post-stroke dysphagia (PSD), valid screening parameters are crucial as part of a step-wise diagnostic procedure. This study examines the role of the National Institute of Health Stroke Scale (NIH-SS) as a potential low-threshold screening parameter. METHODS: During a ten-year period, 687 newly admitted patients at University Hospital Muenster were included in a retrospective analysis, if they had ischemic or haemorrhagic stroke confirmed by neuroimaging and had received NIH-SS scoring and endoscopic swallowing evaluation upon admission. The NIH-SS score was correlated with dysphagia severity as measured by the validated 6-point fiberoptic endoscopic dysphagia severity score (FEDSS), and the ideal cut-off score to predict PSD, defined as FEDSS > 1, was calculated. Supra- and infratentorial strokes were analysed separately due to their differing role in the pathophysiology of neurogenic dysphagia. RESULTS: NIH-SS and dysphagia severity show a significant positive correlation in the whole study population (R2 = 0.745) as well as in both analysed subgroups (R2 = 0.494 for supra- and R2 = 0.646 for infratentorial strokes, p < 0.0005, respectively). For supratentorial strokes, the ideal NIH-SS cut-off is > 9 (sensitivity 68.3%, specificity 61.5%, positive predictive value 89.7%, negative predictive value 28.4%). For infratentorial strokes, a lower ideal cut-off > 5 was calculated (sensitivity 67.4%, specificity 85.0%, positive predictive value 95.1%, negative predictive value 37.8%). CONCLUSIONS: NIH-SS may be used as an adjunct to predict dysphagia in acute stroke patients with moderate sensitivity and specificity. Differentiation between supra- and infratentorial regions is essential not to miss dysphagia in infratentorial stroke.
