Reliability and validity of the Italian Eating Assessment Tool

An Evaluation of Psychometric Properties of EAT-10: A Malayalam Version

The Eating Assessment Tool (EAT-10) is a 10-item self-administered questionnaire that assesses the severity of dysphagia symptoms, the impact of dysphagia on quality of life and treatment efficacy. EAT-10 has been adapted into several languages, including Malayalam. However, the information on the psychometric properties of EAT-10 MALAYALAM is not known. Therefore, the study aimed to evaluate the psychometric properties of the EAT-10 MALAYALAM. EAT-10 MALAYALAM questionnaire was administered to two groups of native Malayalam-speaking participants. Group 1 consisted of a total of 110 participants (76 males and 34 females) with a mean age of 52.9 ± 13.5 years diagnosed with oropharyngeal dysphagia. Group 2 consisted of 110 age and gender-matched healthy participants with normal swallow function and no history and symptoms of swallowing disorders. The test-retest reliability was assessed using Spearman's rank correlation coefficient between the test and the retest scores; internal consistency was assessed using Cronbach's alpha, and Known groups validity was evaluated by comparing the EAT-10 MALAYALAM scores between the participants of both groups. The results of Spearman's correlation coefficient showed 0.99, indicating that the EAT-10-MALAYALAM has excellent test-retest reliability. The Cronbach's alpha was 0.94, indicating strong internal consistency. Mann-Whitney U test showed significant differences in the scores of EAT-10-MALAYALAM between the participants of both groups. Therefore, it was inferred that EAT-10-MALAYALAM had good known groups validity. The EAT-10-MALAYALAM is a valid and reliable tool for screening Malayalam-speaking dysphagia patients.

Surgical and Functional Outcomes of Posterior Cordotomy and Partial Arytenoidectomy with CO2 LASER in the Treatment of Bilateral Vocal Cord Immobility: A Single Institution Experience

Background/Objectives: The purpose of this study is to investigate surgical and functional outcomes of patients affected by bilateral vocal cord immobility (BVCI) and treated with posterior cordotomy and partial arytenoidectomy. Methods: We performed a retrospective analysis on pre- and postoperative findings on a series of 27 patients affected by BVCI and treated with posterior cordotomy and partial arytenoidectomy from January 2017 to January 2022. Perceptual voice evaluations were performed using the GRBAS scale. The patients were requested to estimate the level of voice handicap experienced in their life using the Italian version of Voice Handicap Index 10 (VHI 10) questionnaire, while swallowing difficulties were self-evaluated through the Italian version of the Eating Assessment Tool (EAT-10) questionnaire. Results: Respiratory distress was evaluated according to the American Medical Research Council Dyspnoea Scale (MRC_DS) before and 1 year after the surgery. The mean of the preoperative values was 3.86 (±0.4), while 1 year after the procedure, we witnessed a significant (p ≤ 0.001) improvement, with a mean value of 1.09 (±0.9). After surgery, an overall worsening in voice quality was perceived, with a worsening in the GRBAS score. In contrast, the VHI10 does not show a statistically significant worsening. EAT 10 did not demonstrated worse scores after the surgery; rather, it showed a trend of improvement (preoperative EAT10 5.5 ± 5.8, postoperative 3.3 ± 2.9, p = 0.064). Conclusions: According to our results, posterior cordotomy plus partial arytenoidectomy is an effective procedure that provides stable and rapid respiratory improvement whilst preserving swallowing and the self-perception of voice quality.

Nature, severity, and impact of chronic oropharyngeal dysphagia following curative resection for esophageal cancer: a cross-sectional study

Chronic oropharyngeal dysphagia (COD) and aspiration after esophageal cancer surgery may have clinical significance; however, it is a rarely studied topic. In a prospective cross-sectional observational study we comprehensively evaluated the nature, severity, and impact of COD, its predictors, and the impact of the surgical approach and site of anastomosis. Forty participants were recruited via purposive sampling from the (Irish) National Center between November 2021 and August 2022. Swallow evaluations included videofluoroscopy [Dynamic Imaging Grade of Swallowing Toxicity v2 (DIGESTv2), MBS Impairment Profile, Penetration-Aspiration Scale)]. Functional Oral Intake Scale (FOIS) identified oral intake status. The patient reported outcome measures of swallowing, and Quality of Life (QL) included EAT-10 and MD Anderson Dysphagia Inventory (MDADI). Fourteen (35%) participants presented with COD on DIGESTv2 and 10% had uncleared penetration/aspiration. Avoidance or modification of diet on FOIS was observed in 17 (42.5%). FOIS was associated with pharyngeal dysphagia (OR = 4.05, P = 0.046). Median (range) EAT-10 and MDADI Composite results were 3(0-30) and 77.9(60-92.6), respectively. Aspiration rates significantly differed across surgical groups (P = 0.029); only patients undergoing transhiatal surgery aspirated. Survivors of esophageal cancer surgery may have COD that is undiagnosed, potentially impacting swallow-related QL. Given the small number of aspirators, further research is required to determine whether aspiration risk is associated with surgical approach. A FOIS score below 7 may be a clinically useful prompt for the MDT to refer for evaluation of COD following curative intent surgery. These data present findings that may guide preventive and rehabilitative strategies toward optimizing survivorship.

Translation and validation of traditional Chinese version of the pediatric eating assessment Tool-10

BACKGROUND

/Purpose: The Pediatric Eating Assessment Tool-10 (Pedi-EAT-10) is a caregiver-administrated subjective questionnaire for evaluating swallowing and feeding disorders among children. This study translated the Pedi-EAT-10 into Traditional Chinese and tested the translated version's reliability and validity.

METHODS

Pedi-EAT-10 was translated into Traditional Chinese by experts and finalized after discussion and testing. A total of 168 participants, consisting of 32 children with dysphagia from a tertiary medical center and 136 healthy controls from its Children Care Center for Employees, were recruited. All participants were assessed by an otolaryngologist and speech-language pathologist. The reliability, validity, and efficacy of the translated Pedi-EAT-10 were analyzed to ensure it could be used to identify pediatric dysphagia and feeding problems.

RESULTS

The Traditional Chinese version of the Pedi-EAT-10 had significant clinical discriminative validity between the dysphagia group and the control group (total score = 9.6 vs. 2.6, P < 0.001), acceptable test-retest reliability (intraclass correlation = 0.63), and excellent internal consistency (Cronbach's α = 0.91 for the entire cohort). The overall performance of the test for distinguishing children with dysphagia from normal controls was acceptable, and the area under the curve was 74.8% (sensitivity = 71.9%; specificity = 69.9%). The optimal cutoff score was ≥3 on the Youdex index.

CONCLUSIONS

The Traditional Chinese version of the Pedi-EAT-10 has fair reliability and validity and can be quickly and easily completed by caregivers. The translated Ped-EAT-10 can be used as a first-line tool for assessing the need for further referral and instrumental examination.

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.

Symptoms of oropharyngeal dysphagia, efficiency, and safety of swallowing in patients after treatment for head and neck cancer

PURPOSE

The aim of this study is to investigate the relation between symptoms and signs of oropharyngeal dysphagia after treatment for head and neck cancer.

METHODS

An observational analytical study with retrospective and prospective components was carried out including 25 adult and elderly patients with head and neck cancer who had completed the treatment at least 3 months before data collection. Data from the Eating Assessment Tool (EAT-10) protocol were analyzed, as well as from the videofluoroscopic swallowing exams. Based on videofluoroscopy, the degree of oropharyngeal dysphagia was classified, as well as the safety and efficiency grade using the DIGEST (Dynamic Imaging Grade of Swallowing Toxicity) scale. Pearson's correlation test was applied, adopting a significance level of 5%.

RESULTS

There was a significant correlation between question 4 of the EAT-10 (swallowing solids takes extra effort) and the efficiency profile (p = 0.004), as well as between question 4 and the DIGEST score (p = 0.002). No significant relation was found between the DIGEST score and EAT-10 total score (p = 0.180) and not even between EAT-10 total score and efficiency (p = 0.129) or safety grade (p = 0.878).

CONCLUSION

In conclusion, no relation was found between most of the dysphagia signs and symptoms investigated, demonstrating that the individual's perception of the swallowing function may not be consistent with the findings of the instrumental evaluation after long-term treatment for head and neck cancer.

Eating Assessment Tool (EAT-10) Scores to Detect Self-Reported Dysphagia in Brazilians

The Eating Assessment Tool (EAT-10) detects swallowing impairments (dysphagia) self-reported by patients according to their perception. This noninvasive, inexpensive, self-administered instrument is quickly and easily filled out. The objective of this investigation was to evaluate the scores, sensitivity, and specificity of the method to define self-reported dysphagia in Brazilians. EAT-10 scores were evaluated in 443 healthy individuals (273 women and 170 men), aged 20 to 84 years, with no swallowing difficulties or diseases, and 72 patients with diseases that cause dysphagia (35 women and 37 men), aged 29 to 88 years. Each of the 10 instrument items has a 0-4 rating scale, in which 0 indicates no problem and 4, a severe problem; total results range from 0 to 40. The median EAT-10 score of healthy subjects was 0 (range: 0-20), and that of patients was 14.5 (range: 1-40). Considering a ≥ 3 cutoff score to define dysphagia risk, it was self-reported by 97.2% of patients with dysphagia and 9.5% of no-disease individuals (97.2% sensitivity and 90.7% specificity). The positive predictive value of the test was 63% and the negative predictive value was 99.5%. Healthy women had higher scores (median 0, range: 0-20) than healthy men (median 0, range: 0-8, p < 0.01) and more results indicative of self-reported dysphagia (11.7%) than healthy men (5.9%). The EAT-10 cutoff score to detect self-reported dysphagia in Brazilians should be 3, as previously considered. Healthy women complain more of self-reported dysphagia than healthy men. The test has high sensitivity and specificity.

Consensus for voice quality assessment in clinical practice: guidelines of the European Laryngological Society and Union of the European Phoniatricians

INTRODUCTION

To update the European guidelines for the assessment of voice quality (VQ) in clinical practice.

METHODS

Nineteen laryngologists-phoniatricians of the European Laryngological Society (ELS) and the Union of the European Phoniatricians (UEP) participated to a modified Delphi process to propose statements about subjective and objective VQ assessments. Two anonymized voting rounds determined a consensus statement to be acceptable when 80% of experts agreed with a rating of at least 3/4. The statements with ≥ 3/4 score by 60-80% of experts were improved and resubmitted to voting until they were validated or rejected.

RESULTS

Of the 90 initial statements, 51 were validated after two voting rounds. A multidimensional set of minimal VQ evaluations was proposed and included: baseline VQ anamnesis (e.g., allergy, medical and surgical history, medication, addiction, singing practice, job, and posture), videolaryngostroboscopy (mucosal wave symmetry, amplitude, morphology, and movements), patient-reported VQ assessment (30- or 10-voice handicap index), perception (Grade, Roughness, Breathiness, Asthenia, and Strain), aerodynamics (maximum phonation time), acoustics (Mean F0, Jitter, Shimmer, and noise-to-harmonic ratio), and clinical instruments associated with voice comorbidities (reflux symptom score, reflux sign assessment, eating-assessment tool-10, and dysphagia handicap index). For perception, aerodynamics and acoustics, experts provided guidelines for the methods of measurement. Some additional VQ evaluations are proposed for voice professionals or patients with some laryngeal diseases.

CONCLUSION

The ELS-UEP consensus for VQ assessment provides clinical statements for the baseline and pre- to post-treatment evaluations of VQ and to improve collaborative research by adopting common and validated VQ evaluation approach.

Development and Validation of a Predictive Model to Evaluate the Risk of Dysphagia Following Anterior Cervical Discectomy and Fusion

STUDY DESIGN

A retrospective study.

OBJECTIVE

To investigate the potential risk factors of dysphagia after anterior cervical discectomy and fusion (ACDF) and to establish and validate a prediction model.

METHODS

The clinical data of 252 patients who underwent anterior cervical discectomy and fusion in our hospital from January 2018 to October 2020 were retrospectively analyzed and divided into the dysphagia group and the non-dysphagia group according to whether dysphagia occurred after surgery. Age, gender, body mass index, smoking and drinking history, hypertension history, diabetes history, disease duration, placement of Hemovac negative pressure drain, number of segments involved in surgery, whether C4-5/C5-6 segment surgery, incision length, incision position, level of preoperative EAT-10 score, whether preoperative tracheal exercise, and changes in cervical curvature before and after surgery were recorded in both groups. Risk factors for postoperative dysphagia were identified and nomogram prediction models were developed.

RESULTS

A total of 252 patients were included in the study, 115 of whom presented with dysphagia within 1 week after anterior cervical fusion. The results of multivariate logistic regression analysis indicated that male gender (OR = .045, 95% CI .223-.889) and whether preoperative tracheal exercise (OR = .260, 95% CI .107-.633) were independent risk factors associated with reduced incidence of postoperative dysphagia.

CONCLUSION

The incidence of dysphagia symptoms after anterior cervical decompression and fusion gradually decreased with the extension of follow-up time, and preoperative tracheal exercise and shortening the operation time may help to reduce the occurrence of postoperative dysphagia.

Sarcopenic Dysphagia and Simplified Rehabilitation Nutrition Care Process: An Update

Sarcopenic dysphagia is characterized by weakness of swallowing-related muscles associated with whole-body sarcopenia. As the number of patients with sarcopenia increases with the aging of the world, the number of patients with sarcopenic dysphagia is also increasing. The prevalence of sarcopenic dysphagia is high in the institutionalized older people and in patients hospitalized for pneumonia with dysphagia in acute care hospitals. Prevention, early detection and intervention of sarcopenic dysphagia with rehabilitation nutrition are essential. The diagnosis of sarcopenic dysphagia is based on skeletal and swallowing muscle strength and muscle mass. A reliable and validated diagnostic algorithm for sarcopenic dysphagia is used. Sarcopenic dysphagia is associated with malnutrition, which leads to mortality and Activities of Daily Living (ADL) decline. The rehabilitation nutrition approach improves swallowing function, nutrition status, and ADL. A combination of aggressive nutrition therapy to improve nutrition status, dysphagia rehabilitation, physical therapy, and other interventions can be effective for sarcopenic dysphagia. The rehabilitation nutrition care process is used to assess and problem solve the patient's pathology, sarcopenia, and nutrition status. The simplified rehabilitation nutrition care process consists of a nutrition cycle and a rehabilitation cycle, each with five steps: assessment, diagnosis, goal setting, intervention, and monitoring. Nutrition professionals and teams implement the nutrition cycle. Rehabilitation professionals and teams implement the rehabilitation cycle. Both cycles should be done simultaneously. The nutrition diagnosis of undernutrition, overnutrition/obesity, sarcopenia, and goal setting of rehabilitation and body weight are implemented collaboratively.

Validation of dysphagia perception to predict the risk for dysphagia in non-institutionalized older adults

BACKGROUND AND AIMS

Dysphagia is a swallowing disorder that affects mainly the older adults and can compromise quality of life, and increase the risk for malnutrition and aspiration. Early diagnosis is, therefore, essential to prevent adversities. We aimed to evaluate the validity of self-perceived dysphagia in community-dwelling older adults (60 years or older) from Pelotas, Brazil, participants in the "COMO VAI?"

STUDY

METHODS

The Eating Assessment Tool (EAT-10) was used as the reference tool to identify the risk for dysphagia and the self-perception of dysphagia was assessed using the following question: "Do you have swallowing difficulties?" (Yes/No). The parameters of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were described with 95% confidence intervals (95% CI) and according to independent variables (sex, age, economic level, and education).

RESULTS

The prevalence of dysphagia risk according to EAT-10 and self-perception was 12.9% (95% CI 10.2-16.1) and 8.8% (95% CI 6.6-11.6), respectively. Sensitivity was 34.8% (95% CI 23.5-47.6) and the highest values were observed in women and the older individuals (80 years or older). Specificity was 95.1% (95% CI 92.6-96.9). PPV was 51.1% (95% CI 35.8-66.3), NPV 90.8% (95% CI 87.8-93.2) and accuracy 87.3%.

CONCLUSIONS

Considering the low sensitivity and PPV, the self-perception of dysphagia analyzed with a single question should be used with caution, as an individual at risk for dysphagia may not realize their condition.

Development and Evaluation of the Psychometric Properties of the Tamil Version of Eating Assessment Tool - 10 (EAT-10): Preliminary Findings from Persons with Head and Neck Cancer

Aims: This study aimed to develop and evaluate the psychometric properties of the Tamil version of the Eating Assessment Tool (EAT-10). Setting & Study Design: Prospective cross-sectional study on persons with Head and Neck Cancer (HNC) during their follow-up for oncological and swallowing consultation at a tertiary care hospital and healthy individuals recruited from the community. Methods: The study was conducted in two phases: (1) translation and development of the Tamil version of EAT-10 and (2) administration of Tamil EAT-10 to assess internal consistency reliability, test-retest reliability and known-group validity. 92 participants with HNC in the clinical group and 149 healthy adults in the control group completed the Tamil EAT-10. In addition, a subgroup of 20 participants with HNC repeated the questionnaire within a week to assess test-retest reliability. Results: The Cronbach alpha for the 10 items was 0.96 indicating high internal consistency reliability. The test-retest reliability of the individual items and the total scores (r = 0.98) of the Tamil version of EAT-10 were high. The total EAT-10 scores for the HNC group (14.4 ± 11.5) were significantly higher (p < 0.001) than the scores for healthy adults (0.72 ± 2.0). Conclusion: The Tamil version of the EAT-10 developed in this study is a reliable and valid self-administered tool for identifying concerns related to swallowing among persons treated for HNC and healthy adults. This tool can be implemented for clinical practice and research in dysphagia among a Tamil-speaking population.

Trans-Adaptation and Analysis of Psychometric Properties of Hindi Version of Eating Assessment Tool-10 (EAT-10H)

The present study aims to trans-adapt the Eating Assessment Tool-10 (EAT-10) to the Hindi language and assess its psychometric properties. The original EAT-10 was translated into Hindi language using the forward-backward translation method. A total of 201 participants were included in the study. Among 201 participants, 83 were controls, and 118 were dysphagic. Internal consistency, reliability, and clinical validity were measured. Results revealed that the Hindi version of EAT-10 exhibited an excellent internal consistency (i.e., 0.86). A significant difference was found between the mean scores of both groups, and an excellent reliability score (i.e., 0.96) was obtained. From the present study's findings, it can be delineated that the Hindi version of EAT-10 exhibited good psychometric properties. So, the developed tool is a quick, reliable, and valid tool.

Prevalence of Oropharyngeal Dysphagia in Adults in Different Healthcare Settings: A Systematic Review and Meta-analyses

Oropharyngeal dysphagia (OD) is prevalent in the elderly and persons with complex medical conditions, resulting in considerable medical and psychosocial consequences and reduced quality of life. Many prevalence studies regard OD in relation to age or diagnosis. Knowledge on the prevalence of OD in different healthcare settings is lacking. This systematic review aimed to estimate the prevalence of OD in adults admitted to hospitals, rehabilitation facilities, nursing homes, and palliative care facilities through meta-analyses. A systematic literature search was completed including all dates up to March 30, 2021. The methodology and reporting were based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Forty-four out of 1,956 screened articles were deemed eligible. Considerable heterogeneity in definitions of OD and type and quality of selected outcome measures were observed. Overall within-group pooled prevalence estimates for OD determined by meta-analysis were 36.5% (95% CI 29.9 - 43.6) in the hospital setting, 42.5% (95% CI 35.8 - 49.5) in the rehabilitation setting, and 50.2% (95% CI 33.3-67.2) in nursing homes. No OD prevalence data were identified for palliative care facilities. Results for between-group analyses of OD prevalence estimates in the hospital setting were non-significant for type of assessment method, diagnostic group, and type of hospital ward, but indicated significantly higher prevalence estimates in nursing homes when using screening compared to patient-report. Future research should provide OD prevalence data for palliative care, achieve consensus in OD-related terminology when performing prevalence studies, and use screening and assessments with optimal diagnostic performance and psychometric properties.

Diagnostic Accuracy of the Eating Assessment Tool-10 (EAT-10) in Screening Dysphagia: A Systematic Review and Meta-Analysis

The Eating Assessment Tool-10 (EAT-10) is used worldwide to screen people quickly and easily at high risk for swallowing disorders. However, the best EAT-10 cutoff value is still controversial. In this systematic review and meta-analysis, we estimated and compared the diagnostic accuracy of EAT-10 cutoff values of 2 and 3 for screening dysphagia. We searched the PubMed, Web of Science, EMBASE, Cochrane Library, CNKI, WANFANG, and VIP databases from May 2008 to March 2022. The meta-analysis included 7 studies involving 1064 subjects from 7 different countries. Two studies were classified as high quality and five studies as medium quality. With an EAT-10 cutoff value of 2, using flexible endoscopic evaluation of swallowing or video fluoroscopic swallowing study as the gold standard, the pooled sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio were 0.89 (95% confidence interval [CI] 0.82-0.93), 0.59 (95% CI 0.39-0.77), 2.17 (95% CI 1.38-3.42), 0.19 (95% CI 0.13-0.29), and 11.49 (95% CI 5.86-22.53), respectively. When a cutoff of 3 was used, these values were 0.85 (95% CI 0.68-0.94), 0.82 (95% CI 0.65-0.92), 4.84 (95% CI 1.72-13.50), 0.18 (95% CI 0.07-0.46), and 26.24 (95% CI 5.06-135.95), respectively. Using EAT-10 cutoff values of 2 and 3, the areas under the curve were 0.873 (95% CI 0.82-0.93) and 0.903 (95% CI 0.88-0.93), respectively, showing good diagnostic performance. EAT-10 can be used as a preliminary screening tool for dysphagia. However, a cutoff of 3 is recommended for EAT-10 due to better diagnostic accuracy.

History and Science behind the Eating Assessment Tool-10 (Eat-10): Lessons Learned

INTRODUCTION

Oropharyngeal dysphagia (OD) is an underdiagnosed medical condition with a high prevalence in populations such as patients with frailty, neurological disease, or head and neck pathology. Potential barriers to its diagnosis include lack of (or low) awareness of the existence and severity of the condition, the hidden nature of the condition within the 'normal ageing' process, clinical limitations, and socioeconomic reasons. Consequently, an effective treatment is not systematically offered in a timely manner, and complications, such as dehydration and respiratory infections or aspiration pneumonia, can arise. To overcome this issue, the early use of screening questionnaires to identify people at risk of swallowing disorders represents the cornerstone of preventive medicine. Several screening tools have been created but few are widely used in clinical practice. The Eating Assessment Tool-10 (EAT-10) was developed as a quick, easy-to-understand, and self-administered screening tool for OD.

METHODS

A literature review was conducted in five databases with no restrictions on the language, date of publication, or design of the study to identify aspects of the validation, applicability, and usefulness of EAT-10.

RESULTS AND CONCLUSIONS

Transcultural adaptation and translation studies, as well as studies involving various types of patients with dysphagia in different settings have shown the validity and reliability of EAT-10 in relation to the gold standard and other validation tools. The use of this standardised screening tool could be used as a primary screening instrument of dysphagia in routine clinical practice across a wide range of diseases and settings and thereby increase the likelihood of early diagnosis and management of a condition that lead to serious complications and impaired quality of life.

Functional outcomes after transoral CO2 laser treatment for posterior glottic stenosis: a bicentric case series

PURPOSE

The aim of this study is to evaluate functional outcomes in terms of decannulation rate and quality of life of patients affected by PGS (Grades I-IV) treated only by transoral CO₂ laser microsurgery (TOLMS) in two tertiary centers.

METHODS

An observational retrospective study was carried out, enrolling 22 patients affected by PGS who were treated by a transoral approach at two tertiary referral centers. Surgical treatment included TOLMS with tailored laser resection of the scar tissue combined with posterior cordotomy, resurfacing of the raw area with mucosal microflap, or placement of a Montgomery T-tube or Keel stent. All patients were evaluated and staged preoperatively and postoperatively, at least 6 months after the surgery. Functional outcomes were objectively evaluated by the Airway-Dysphonia-Voice-Swallowing (ADVS) staging system, Voice Handicap Index-30 (VHI-30), and Eating Assessment Tool-10 (EAT-10) questionnaires.

RESULTS

Quality of life significantly improved as measured by the VHI-30 questionnaire with a median variation of - 31.0 (p = 0.003), the EAT-10 with a median variation of - 4.0 (p = 0.042), and the ADVS with a median variation of - 3.5 (p < 0.001). No significant changes were observed in swallowing scores. We were able to decannulate 7 of 9 patients (almost 80%) with previous tracheotomy.

CONCLUSION

In conclusion, even if there is still no general agreement on an exact therapeutic algorithm to treat PGS, our results confirm that transoral surgery, in terms of scar tissue removal, combined in selected patients with posterior cordotomy and pedicled local flaps and/or placement of stents, represents a safe and effective surgical approach even for more severe PGS.

Effects of Intraoperative Nerve Monitoring Techniques on Voice and Swallowing Disorders after Uncomplicated Thyroidectomy: Preliminary Report of a Bi-Institutional Prospective Study

Background: Voice and swallowing problems are frequently associated with thyroidectomy. Intermittent nerve monitoring (i-IONM) seems to provide a positive effect in reducing its prevalence. The aim of this study was to test the hypothesis that continuous intraoperative nerve monitoring (c-IONM) may reduce the prevalence of these disorders even further than i-IONM. Methods: This 3-arm prospective bi-institutional study compared 179 consecutive patients that underwent thyroidectomy: 56 without IONM, 55 with i-IONM and 67 with c-IONM. Neck dissections and laryngeal nerve palsies were excluded. Two questionnaires (VHI-10 for voice disorders and EAT-10 for swallowing disorders; both validated for Italian language use) were administered before and 1 month after surgery. Statistical significance was analyzed by the chi-squared test. Results: After thyroidectomy, no statistically significant differences were found in the three groups concerning EAT-10. although these symptoms seemed to be influenced by gastro-esophageal reflux. VHI-10 worsened in the “no-IONM” group compared with both i-IONM (p < 0.09, not quite statistically significant) and c-IONM (p < 0.04). Conclusion: Both i- and c-IONM improve voice quality independently of laryngeal nerve integrity. Reduced dissection and particularly restrained manipulation could explain these results, being particularly favorable for c-IONM.

Cross-cultural Adaption, Validation and Factor Analysis of the Persian Version of the Eating Assessment Tool: EAT-10

The eating assessment tool (EAT-10) is a self-reported questionnaire to assess the patient's perception of swallowing difficulties. The aim of this study was to cross-culturally adapt and determine validity and reliability of the Persian version of the EAT-10 (P-EAT-10) in patients with oropharyngeal dysphagia. The EAT-10 was translated into Persian language and cross-culturally adapted. One hundred patients with dysphagia (mean age ± SD = 44.44 ± 14.69 years) participated. The test-retest reliability (time interval = 7 days) was assessed in 50 patients. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and smallest detectable change (SDC) were analyzed. The Persian version of functional oral intake scale (FOIS-P) was also recorded to assess construct validity. One hundred healthy subjects completed the P-EAT-10 for clinical validity. Factor analysis was performed to determine the P-EAT-10 structure. There were no missing responses and floor or ceiling effects. Internal consistency was high (Cronbach's α 0.91). Item-total correlations exceeded acceptable standard of 0.3 for the all items (0.62-0.83). The test-retest reliability was excellent [(ICC)_agreement 0.96]. The SEM and SDC were 2.61 and 7.23, respectively. Construct validity was confirmed by a significant correlation between the P-EAT-10 and FOIS-P scores (r = 0.84). Clinical validity was supported by a significant discrimination between patients and healthy subjects (t = 29.97, P < 0.001). Factor analysis indicated 2 components for the P-EAT-10. The P-EAT-10 is a valid and reliable tool and can be used in clinic and research for the assessment of oropharyngeal dysphagia in Persian-speaking patients.

Discriminant Ability of the Eating Assessment Tool-10 to Detect Swallowing Safety and Efficiency Impairments

OBJECTIVES/HYPOTHESIS

Quick, sensitive dysphagia screening tools are necessary to identify high-risk patients for further evaluation in busy multidisciplinary amyotrophic lateral sclerosis (ALS) clinics. We examined the relationship between self-perceived dysphagia using the validated Eating Assessment Tool-10 (EAT-10) and videofluoroscopic analysis of swallowing safety and efficiency.

STUDY DESIGN

Prospective, observational, longitudinal study.

METHODS

Individuals with ALS completed the EAT-10 and a videofluoroscopic swallowing study. Duplicate, independent, blinded analyses of the validated Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scale were performed to index swallowing safety and efficiency (mild dysphagia: DIGEST ≥ 1, moderate dysphagia: DIGEST ≥ 2). A between-groups analysis of variance with Games-Howell test for post-hoc pairwise comparisons was performed to examine EAT-10 scores across dysphagia severity levels. Receiver operator characteristic curve analysis, area under the curve (AUC), sensitivity, specificity, positive-negative predictive values (PPV, NPV), and odds ratios (OR) were derived.

RESULTS

Four hundred and thirty five paired EAT-10 and DIGEST scores were analyzed. Mean EAT-10 score was 8.48 (95% confidence interval [CI]: 7.63-9.33). Individuals with dysphagia demonstrated higher EAT-10 scores (mild: 4.1 vs. 11.3, moderate: 6.0 vs. 17.5, P < .001). Mean EAT-10 scores increased across DIGEST levels (D0: 4.1, D1: 7.9, D2: 15.1, D3: 20.4, D4: 39.0). For mild dysphagia, an EAT-10 cut score of 3 was optimal: AUC 0.74 (95% CI: 0.69-0.78; sensitivity: 77%; specificity: 53%; PPV: 71%; NPV: 60%; OR: 3.5). An EAT-10 cut score of 7 optimized detection of moderate dysphagia: AUC 0.83 (95% CI: 0.78-0.87; sensitivity: 81%; specificity: 66%; PPV: 39%; NPV: 93%; OR: 8.1).

CONCLUSION

The EAT-10 is an easy-to-administer dysphagia screening tool with good discriminant ability for use in ALS clinics.

Slovak Translation and Cross-Cultural Validation of the Eating Assessment Tool (EAT10®)

Introduction: The objective of the study was the language adaptation and verification of psychometric properties of the Slovak version of the EAT10® questionnaire. Methods: The original English version of the questionnaire was translated into the Slovak language. The research group included 136 control participants and 51 dysphagic patients. Test−retest reliability, item analysis, internal consistency, construct and clinical validity, and Receiver Operating Characteristic (ROC) analysis were performed to verify the psychometric properties of the Slovak EAT10®. Results: The internal consistency assessed with Cronbach’s alpha is excellent (α = 0.94). Statistical analysis of the Slovak version of EAT10® showed excellent reliability (0.91, p < 0.001) in the test−retest. Through item-to-total correlation, we found out that all items significantly correlated with the overall score in EAT10®. Factor analysis proved a high construct validity. The EAT10® questionnaire was able to reveal a latent variable: a swallowing disorder, which was affecting a group of patients. The clinical validity results confirmed statistically significant differences in the mean scores of the control and dysphagic groups (z = −10.30; p < 0.001). By dividing the dysphagic group into four subgroups (Head and Neck Cancer, Extraesophageal Reflux, Iatrogenic, and Neurological) there were nonsignificant differences in the mean scores of the subgroups. The cut-off value for the Slovak EAT10® is three points. Conclusion: The Slovak EAT10® is a valid and reliable tool designed for the subjective assessment of oropharyngeal dysphagia in patients.

Prevalence and management of dysphagia in nursing home residents in Europe and Israel: the SHELTER Project

Background

Dysphagia is a frequent condition in older nursing home residents (NHRs) which may cause malnutrition and death. Nevertheless, its prevalence is still underestimated and there is still debate about the appropriateness and efficacy of artificial nutrition (AN) in subjects with severe dysphagia. The aim is to assess the prevalence of dysphagia in European and Israeli NHRs, its association with mortality, and the relationship of different nutritional interventions, i.e. texture modified diets and AN—with weight loss and mortality.

Methods

A prospective observational study of 3451 European and Israeli NHRs older than 65 years, participating in the SHELTER study from 2009 to 2011, at baseline and after 12 months. All residents underwent a standardized comprehensive evaluation using the interRAI Long Term Care Facility (LTCF). Cognitive status was assessed using the Cognitive Performance Scale (CPS), functional status using Activities of Daily Living (ADL) Hierarchy scale. Trained staff assessed dysphagia at baseline by clinical observation. Data on weight loss were collected for all participants at baseline and after 12 months. Deaths were registered by NH staff.

Results

The prevalence of dysphagia was 30.3%. During the one-year follow-up, the mortality rate in subjects with dysphagia was significantly higher compared with that of non-dysphagic subjects (31.3% vs 17.0%,p = 0,001). The multivariate analysis showed that NHRs with dysphagia had 58.0% higher risk of death within 1 year compared with non-dysphagic subjects (OR 1.58, 95% CI, 1.31–1.91). The majority of NHRs with dysphagia were prescribed texture modified diets (90.6%), while AN was used in less than 10% of subjects. No statistically significant difference was found concerning weight loss and mortality after 12 months following the two different nutritional treatments.

Conclusions

Dysphagia is prevalent among NHRs and it is associated with increased mortality, independent of the nutritional intervention used. Noticeably, after 12 months of nutritional intervention, NHRs treated with AN had similar mortality and weight loss compared to those who were treated with texture modified diets, despite the clinical conditions of patients on AN were more compromised.

Cross-Cultural Adaptation and Validation of the Italian Version of the Dysphagia Handicap Index (I-DHI)

The Dysphagia Handicap Index (DHI) is a valid Health-related Quality of Life (HRQOL) questionnaire for patients with oropharyngeal dysphagia (OD) of heterogeneous etiologies. The study aimed at crossculturally translating and adapting the DHI into Italian (I-DHI) and analyzing I-DHI reliability, validity, and interpretability. The I-DHI was developed according to Beaton et al. 5-stage process and completed by 75 adult OD patients and 166 healthy adults. Twenty-six patients filled out the I-DHI twice, 2 weeks apart, for test–retest reliability purposes. Sixty-two patients completed the Italian-Swallowing Quality of Life Questionnaire (I-SWAL-QoL) for criterion validity analysis. Construct validity was tested comparing I-DHI scores among patients with different instrumentally assessed and self-rated OD severity, comparing patients and healthy participants and testing Spearman’s correlations among I-DHI subscales. I-DHI interpretability was assessed and normative data were generated. Participants autonomously completed the I-DHI in maximum 10 min. Reliability proved satisfactory for all I-DHI subscales (internal consistency: α > .76; test–retest reliability: intraclass correlation coefficient > .96, k = .81). Mild to moderate correlations (− .26 ≤ ρ ≤ − .72) were found between I-DHI and I-SWAL-QoL subscales. Construct validity proved satisfactory as (i) moderate to strong correlations (.51 ≤ ρ ≤ .90) were found among I-DHI subscales; (ii) patients with more severe instrumentally or self-assessed OD reported higher I-DHI scores (p < .05); and (iii) OD patients scored higher at I-DHI compared to healthy participants (p < .05). Interpretability analyses revealed a floor effect for the Emotional subscale only and higher I-DHI scores (p < .05) for healthy participants > 65 years. In conclusion, the I-DHI is a reliable and valid HRQOL tool for Italian adults with OD.

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.

Obstructive sleep apnoea after radiotherapy for head and neck cancer

Objective

The aim of this study is to focus attention on obstructive sleep apnoea hypopnoea syndrome (OSHAS) as a sequela of non-surgical treatments of selected head and neck cancer (HNca), sharing our experience in drug-induced sleep endoscopy (DISE). To the best of our knowledge, this is the first study that documents dynamic anatomical and functional alterations during sleep in irradiated OSAHS patients by DISE.

Methods

A retrospective study of patients affected by OSAHS referring to our department from January 2018 to December 2019 was carried out. Inclusion criteria were: patients who underwent radiation or chemo-radiation for HNca affecting upper airways that presented sleep-related breathing disorders after treatment.

Results

6 patients with moderate to severe OSAHS and a clinical story of previous non-surgical treatment for an HNca were enrolled. DISE showed in all patients typical anatomical alterations observed in irradiated individuals. Four patients were treated with continuous positive airway pressure, while 2 subjects were treated with tailored minimal invasive surgery without post-operative complications.

Conclusions

Our results suggest that minimal invasive surgical treatments can be a good therapeutic option in very selected patients with post-irradiation iatrogenic OSAHS.

Quality of life after transoral CO2 laser posterior cordotomy with or without partial arytenoidectomy for bilateral adductor vocal cord paralysis

Objectives

Bilateral adductor vocal cord paralysis (BAVCP) is a rare and challenging condition whose main consequence is reduction of airway patency at the glottic level, often causing respiratory distress, while vocal function tends to remain almost normal. We investigated the effect of transoral glottal widening on quality of life and decannulation rates in patients affected by BAVCP.

Methods

We retrospectively evaluated patients affected by BAVCP and treated by transoral CO₂ posterior cordotomy with or without medial partial arytenoidectomy (PC ± MPA) at two referral centers. The primary outcome was change in quality of life, evaluated pre- and post-operatively by the ADVS, VHI-30, and EAT-10 questionnaires. Secondary outcomes were the need for retreatments and, for patients with tracheotomy, the time to decannulation.

Results

Thirty-three patients met selection criteria. The etiology was post-surgical in 27 cases (81.8%), idiopathic in 4 (12.1%), a trauma-related in 1 (6.0%), and to other causes in 1 (3.0%). In 22 cases (66.7%), PC was combined with MPA. A significant improvement in responses for the ADVS (p < .0001) and EAT-10 (p < .0001) was observed, whereas the VHI-30 score did not change significantly post-operatively. All nine patients with a tracheostomy were successfully decannulated within 18 months after the surgical procedure.

Conclusions

For patients affected by BAVCP, PC ± MPA by transoral CO₂ laser microsurgery is a safe, customizable and minimally invasive treatment that can guarantee an affordable balance between quality of life in terms of phonation and swallowing and acceptable airway patency.

Timing of Surgical Intervention for Dysphagia in Patients With Diffuse Idiopathic Skeletal Hyperostosis: A Systematic Review and Meta-Analysis

STUDY DESIGN

This was a systematic review and meta-analysis.

OBJECTIVE

The objective was (1) to measure rates of successful resolution of dysphagia in patients after undergoing surgical intervention for diffuse idiopathic skeletal hyperostosis (DISH); and (2) to determine if older age, longer duration of preoperative symptoms, or increased severity of disease was correlated with unsuccessful surgical intervention.

SUMMARY OF BACKGROUND DATA

DISH, also known as Forestier disease, is an enthesopathy affecting up to 35% of the elderly population. Many patients develop osteophytes of the anterior cervical spine, which contribute to chronic symptoms of dysphagia causing debilitating weight loss and possibly resulting in the placement of a permanent gastrostomy feeding tube. For patients that fail conservative medical management, an increase in surgical interventions have been reported in the literature in the last 2 decades.

MATERIALS AND METHODS

A systematic search was performed on PubMed, Medline, Cochrane Library, and Embase. Studies measuring outcomes after surgical intervention for patients with dysphagia from DISH were selected for inclusion. Two independent reviewers screened and assessed all literature in accordance with Cochrane systematic reviewing standards.

RESULTS

In total, 22 studies reporting 119 patients were selected for inclusion. Successful relief of dysphagia was obtained in 89% of patients after surgical intervention. Failure to relieve dysphagia was associated with increased length of symptoms preoperatively (P<0.01) using logistic regression. Patients with more severe preoperative symptoms also seem to have an increased risk for treatment failure (risk ratio, 2.86; 95% confidence interval, 1.19-6.85; P=0.02). Treatment failure was not associated with patient age, use of intraoperative tracheostomy, implementation of additional fusion procedures, level of involved segments, or number of involved segments.

CONCLUSIONS

Patients undergoing surgical intervention have a higher likelihood of failing surgery with increasing preoperative symptom length and increased preoperative symptom severity.

Cultural Adaptation and Validation of Questionnaires for Evaluation of Health-Related Quality of Life with Dysphagia in Different Countries: A Systematic Review

Dysphagia can have devastating and long-lasting effects on the patient's health-related quality of life (HRQoL). In recent years, a number of questionnaires for the evaluation of the HRQoL of patients with dysphagia have been developed and have been adapted for use in different countries and cultures. However, problems may arise in the process of cultural adaptation and validation, which can affect the quality of the questionnaires and their measurements. This study was conducted to systematically summarize the cultural adaptation and validation of questionnaires for the evaluation of dysphagia-related HRQoL in different countries, assessing the varieties, measurement properties, and qualities of these questionnaires, with the aim of identifying the status of their adaptation and validation and ways in which they might be improved. Four databases were searched, and relevant articles were screened, with data from eligible reports extracted and reviewed. The methodological quality of the included articles was evaluated using the QualSyst critical appraisal tool. The HRQoL questionnaires for patients with dysphagia were assessed using the quality criteria for the measurement properties of health status questionnaires proposed by Terwee et al. and Timmerman et al. 29 studies published between 2008 and 2020 were included. The questionnaires described in these 29 studies were translated into 19 languages and culturally adapted to 21 countries. The adapted questionnaires were based on the Swallowing quality of life questionnaire (SWAL-QOL) by Mchorney et al., the Dysphagia Handicap Index (DHI) by Silbergleit et al., the M.D. Anderson Dysphagia Inventory (MDADI) by Chen et al., and the Eating Assessment Tool-10 (EAT-10) by Belafsky et al. It was found that the questionnaires were reliable and valid instruments for the assessment of dysphagia-related HRQoL, but the quality criteria for cultural adaptation and validation were not strictly followed, especially in the categories of criterion validity, agreement, responsiveness, and interpretability. In conclusion, although the questionnaires were found to be both reliable and valid, the quality criteria should be considered and strictly followed in the cultural adaptation and validation process in the future.

Oropharyngeal Dysphagia After Hospitalization for COVID-19 Disease: Our Screening Results

A high percentage of patients suffered symptoms also after recovery from the Coronavirus Disease—2019 (COVID-19) infection. It is not well clear what are the specific long-term sequelae (complications and symptoms). During the acute phase the patients may develop a multi-organ system pathology including aerodigestive tract. As the pathophysiology of COVID-19 emerges, the aim of our study was to describe the prevalence of oropharyngeal dysphagia after COVID-19 disease. From March to July 2020 we enrolled patients recovered from SARS-CoV-2 infection who had been previously hospitalized for the disease. They were screened for dysphagia by mean of the Eating Assessment Tool-10 (EAT-10). The cases with EAT-10 score > 3 were graded for the aspiration risk by applying the Gugging Swallowing Screen (GUSS) and were submitted to the Swal-QoL questionnaire. The cases with a GUSS score > 19 were subjected to FEES. 8/117 (7%) patients had positive screening result. 4/8 (50%) revealed an abnormal health related quality of life in oropharyngeal dysphagia with a mean Swal-QoL score of 69.73. The most affected domain was the “time of meals” (mean score 65) following by the “sleep” (mean score 66) and “eating desire” (mean score 72). 1/8 cases showed increased risk for aspiration and did not showed endoscopic signs of oropharyngeal dysphagia. Our results showed that the prevalence of upper dysphagia after hospitalization for SARS-CoV-2 is not anecdotal and that probably this long-lasting sequela has a psychogenic etiology.

Dysphagia symptoms in obstructive sleep apnea: prevalence and clinical correlates

BACKGROUND

Epidemiology of dysphagia and its drivers in obstructive sleep apnea (OSA) are poorly understood. The study aims to investigate the prevalence of dysphagia symptoms and their association with demographic and clinical factors in patients with OSA.

METHODS

Patients with OSA referring to an Academic Sleep Outpatient Clinic were enrolled in a prospective study. Demographic, clinical characteristics, and OSA symptoms were collected. All patients underwent home sleep cardiorespiratory polygraphy and the Eating-Assessment Tool questionnaire (EAT-10) to investigate dysphagia symptoms. Patients with a positive EAT-10 were offered to undergo a fiberoptic endoscopic evaluation of swallowing (FEES) to confirm the presence of dysphagia. FEES findings were compared with a healthy control group. Univariate and multivariate analyses were performed to assess predictors of dysphagia.

RESULTS

951 patients with OSA (70% males, age 62 IQR51-71) completed the EAT-10, and 141 (15%) reported symptoms of dysphagia. Female gender (OR = 2.31), excessive daily sleepiness (OR = 2.24), number of OSA symptoms (OR = 1.25), anxiety/depression (OR = 1.89), and symptoms of gastroesophageal reflux (OR = 2.75) were significantly (p < 0.05) associated with dysphagia symptoms. Dysphagia was confirmed in 34 out of 35 symptomatic patients that accepted to undergo FEES. Patients with OSA exhibited lower bolus location at swallow onset, greater pharyngeal residue, and higher frequency and severity of penetration and aspiration events than healthy subjects (p < 0.05).

CONCLUSION

A consistent number of patients with OSA show symptoms of dysphagia, which are increased in females and patients with a greater OSA symptomatology, anxiety and depression, and gastroesophageal reflux. The EAT-10 appears a useful tool to guide the selection of patients at high risk of dysphagia. In clinical practice, the integration of screening for dysphagia in patients with OSA appears advisable.

Correlation Between EAT-10 and Aspiration Risk Differs by Dysphagia Etiology

Agreement between self-reported dysphagic symptoms and actual swallowing physiology can vary widely across individuals. The Eating Assessment Tool-10 (EAT-10) is a self-report questionnaire commonly used to identify individuals with oropharyngeal dysphagia, but its interpretation for highly prevalent populations is poorly defined. Our primary objective was to determine if correlation strength between EAT-10 and Penetration-Aspiration Scale (PAS) scores differed by dysphagia etiology. Our secondary objective was to identify clinical factors that were associated with a mismatch between EAT-10 scores and videofluoroscopic findings. Outpatients with Parkinson disease (PD), stroke, and/or head and neck cancer (HNC) who completed EAT-10 and underwent videofluoroscopy were included (n = 203). EAT-10/PAS correlations were calculated by dysphagia etiology. We found that across the sample, higher EAT-10 scores were significantly correlated to higher PAS scores (r_s = 0.31, p < 0.001). EAT-10 and PAS were moderately correlated in the HNC group (r_s = 0.41, p < 0.001, n = 87), but correlations were modest in the PD (r_s = 0.18, n = 41) and stroke groups (r_s = 0.12, n = 59). Clinical characteristics of individuals with a "matched" profile (normal EAT-10 score and normal swallow physiology) and a "mismatched" profile (normal EAT-10 score and abnormal swallow physiology) were also compared. Individuals with a "mismatched" EAT-10/PAS profile appeared to be significantly older and had a worse Charlson Comorbidity Index than individuals with a "matched" profile. Within the HNC subgroup, EAT-10/PAS correlations for specific tumor sites, treatment types, and time since treatment are reported. Clinicians may consider these aspiration risk profiles when making recommendations for instrumented swallowing assessment.

Tongue strength, dysphagia questionnaire, pharyngeal secretions and FEES findings in dysphagia management in amyotrophic lateral sclerosis

OBJECTIVE

Dysphagia is common in Amyotrophic lateral sclerosis (ALS). ALS shows significant phenotypic variability. It is characterized by progressive weakness and/or spasticity of muscles. Dysphagia symptoms vary. Aspiration is often silent and cognitive dysfunction is common. The purpose of the study was to evaluate tongue strength measurements, dysphagia questionnaire, the presence of pharyngeal secretions, and FEES findings in dysphagia management in ALS.

METHODS

Twenty-five patients completed the Eating Assessment Tool-10 (EAT-10), had their Maximum Isometric Tongue Pressure (MITP), and endurance measured and underwent Flexible Endoscopic Evaluation of Swallowing (FEES) providing 31 examinations.

RESULTS

Out of 25 patients, 76% were self-reported as dysphagic (EAT-10≥3) with a mean EAT-10 at 14.95 (±7.96). ALS patients had significantly decreased tongue strength (mean MITPanterior: 31.69 ± 17.32kPa). Comparing examinations of dysphagic and non-dysphagic status the mean MITPa of non-dysphagic was significantly greater (52.33 ± 10.97 kPa versus 20.6 ± 12.67 kPa), p<0.001. FEES detected aspiration in 10 out of 31 examinations [Penetration Aspiration Scale(PAS) ≥6]. Aspirator status examinations showed statistically significantly worse cough (p = 0.001), tongue strength (p = 0.001) and endurance (p = 0.003), pharyngeal secretions (p<0.001), velopharyngeal sufficiency (p = 0.006), pharyngeal squeeze (p = 0.009), vocal cords' movements (p = 0.001), pharyngeal pooling (p<0.001), EAT-10 (p = 0.001) and bulbar subscale of ALS Functioning Rating Scale-Revised (b-ALSFRS-R) scores (p = 0.014) compared to non-aspirator status. Correlation analysis indicated that the feeding status had strong statistically significant correlations with the EAT-10 score (rho = -0.816), anterior tongue strength (rho = 0.735), secretions (rho = -0.811), pharyngeal pooling (rho = -0.712) and PAS (rho = -0.676) at FEES, and b-ALSFRS-R score (rho = 0.791), all p<0.001. The EAT-10 had strong statistically significant correlations with the MITPa (r = -0.794, p<0.001), secretions (rho = 0.668, p<0.001), and b-ALSFRS-R score (rho = -0.766, p = 0.001). The FEES findings had strong statistically significant correlations with the anterior tongue strength (pooling: rho = -0.784), and secretions (PAS: rho = 0.723; pooling: rho = 0.671), all p<0.001. For the questionnaire, tongue strength and pharyngeal secretions, ROC analysis assessed cut-off points and discriminating ability to predict aspiration status (Area Under the Curve: 0.838; 0.845 and 0.93, respectively). EAT-10 with a cut-off at 8 was able to predict aspirator status with a sensitivity of 100% and a specificity of 42.9% (negative predictive value-NPV = 100%). A cut-off value of 22KPa for the MITPa discriminated aspirator status (sensitivity = 80%, specificity = 89.5%, NPV = 89.5%). The quantity of secretions observed upon endoscopy with a cut-off value at 1 was able to predict aspirator status (sensitivity = 90%, specificity = 80%, NPV = 94.1%).

CONCLUSION

Reduced tongue strength, questionnaire-reported symptoms, pharyngeal secretions, and FESS findings can guide identification of patients with ALS at risk of inefficient and unsafe swallowing.

Validation of the Arabic version of the Eating Attitude Test in Lebanon: a population study

OBJECTIVES

To validate an Arabic version of the Eating Attitude Test (EAT-26) and identify factors (such as depression, stress, anxiety and body dissatisfaction) that might be associated with disordered eating among a sample of the Lebanese population.

DESIGN

Cross-sectional study.

SETTING

All Lebanese governorates.

PARTICIPANTS

A total of 811 participants randomly selected participated in this 5-month study (January-May 2018).

RESULTS

The EAT-26 scale items converged over a solution of six factors that had an eigenvalue over 1, explaining a total of 60·07 % of the variance (Cronbach's α = 0·895). The prevalence of disordered eating attitudes was 23·8 %. Higher EAT-26 scores (disordered eating attitudes) were significantly associated with higher depression (β = 0·325), higher emotional eating (β = 0·083), daily weighing (β = 3·430), higher physical activity (β = 0·05), starving to reduce weight (β = 4·94) and feeling pressure from TV/magazine to lose weight (β = 3·95).

CONCLUSIONS

The Arabic version of EAT-26 can be a useful instrument for screening and assessing disordered eating attitudes in clinical practice and research. Some factors seem to be associated with more disordered eating attitudes among participants for whom psychological counseling may be needed. Yet, our findings are considered preliminary, and further studies are warranted to confirm them.

A prospective study for evaluation of structural and clinical validity of the Eating Assessment Tool

BACKGROUND

The Eating Assessment Tool is a self-rating questionnaire developed to assess symptom severity and treatment efficacy in swallowing disorders. The aim of this study was to investigate the structural validity of the Eating Assessment Tool and whether individual item scores differed between dysphagia secondary to neurological and structural/esophageal disorders, respectively.

METHODS

This is a prospective cross-sectional questionnaire study. In total, 200 community-dwelling adults with suspected dysphagia referred for fiberoptic endoscopic examination of swallowing at Karolinska University Hospital, Stockholm, Sweden, completed the S-EAT-10. Patients' medical charts were reviewed in order to establish the type of dysphagia. Principal axis factoring was conducted to examine structural validity, and Mann-Whitney U tests were used to study differences in the S-EAT-10 score patterns between different types of dysphagia.

RESULTS

One single factor explained 54% of the total variance in EAT-10 item scores. All ten items loaded substantially or strongly on this factor, supporting the single-factor solution (Cronbach's alpha = 0.90). Structural/esophageal dysphagia was associated with higher scores on six items and with a higher total EAT-10 score.

CONCLUSIONS

The EAT-10 yields a unidimensional index of symptom severity in patients with dysphagia. Individual item scores reflect typical symptoms in neurogenic and structural/esophageal dysphagia, supporting its clinical relevance.

Transoral management of adult benign laryngeal stenosis

PURPOSE

Management of benign laryngeal stenosis (BLS) remains challenging even though transoral treatments in selected cases have shown satisfactory results, at least comparable to open-neck approaches, with reduced invasiveness. To date, no overall consensus has been reached on many issues. The aim of this study is to assess the effectiveness of a purely transoral treatment in a cohort of patients affected by BLS.

METHODS

We evaluated 40 patients affected by BLS, treated by transoral surgery between 2013 and 2017. The European Laryngological Society classification for laryngotracheal stenosis was applied for the staging. Improvement in airway patency and quality of life was assessed by decannulation rate, Airway-Dyspnea-Voice-Swallowing (ADVS) score, Voice handicap index (VHI)-30, and Eating assessment tool (EAT)-10 questionnaires.

RESULTS

Mean age was 61 years and M:F ratio was 1.4:1. Previous laryngeal surgery was the most common cause of stenosis (50%), followed by radiotherapy (20%), idiopathic etiology (12%), granulomatosis with polyangiitis (10%), and prolonged intubation (8%). Transoral treatment entailed an improvement in quality of life with a significant decrease in the VHI score (p < 0.0001) and improvement in Airway (p = 0.008), Dyspnea (p < 0.0001), and Voice (p < 0.0001) scores. No major perioperative complications were observed. The decannulation rate among patients with a tracheostomy in place (N = 16) was 63%.

CONCLUSIONS

Transoral treatment of selected BLS managed by a team with high-level expertise in surgery and anesthesiology is associated with significant improvement of quality of life, especially with regard to voice and breathing functions.

Screening dysphagia risk in 534 older patients undergoing rehabilitation after total joint replacement: a cross-sectional study

BACKGROUND

Older people affected by severe osteoarthritis could need to undergo total joint replacement, with a consequent hospitalization and rehabilitation. In this postacute phase, they might suffer from other symptoms, including dysphagia, defined as a dysfunction of the digestive system, characterized by an objective difficulty or a sensation of difficulty in swallowing. It is considered as a very challenging problem in older people and early detection is fundamental for a prompt and effective management. However, up to date, there is a lack of data on dysphagia risk screening in orthopedic rehabilitation inpatients.

AIM

The aim of this study was to evaluate dysphagia risk through Eating Assessment Tool (EAT-10) in older people undergoing rehabilitation after total hip or knee arthroplasty.

DESIGN

Cross-sectional study.

SETTING

Rehabilitation Unit.

POPULATION

All consecutive patients undergone total hip or knee arthroplasty, aged ≥65 years, referring to Orthopedics Rehabilitation Unit "Mons. Luigi Novarese" Hospital, Moncrivello, Italy, for a 24-month period (from 1^st January 2018 to 31^st December 2019). We excluded patients with: 1) diagnosis of neurological diseases; 2) pharyngeal or esophageal cancer; 3) maxillofacial cancer; 4) tracheotomy.

METHODS

Dysphagia risk was assessed through EAT-10. The cohort was divided into two groups, according to water swallowing test (WST), in order to evaluate differences in terms of different EAT-10 scores. Furthermore, based on pathological WST, we have stratified study participants by the American Speech-Language-Hearing Association (ASHA)'s National Outcomes Measurement System (NOMS) swallowing scale in order to evaluate differences in terms of the different EAT-10 scores.

RESULTS

We included 534 participants (180 men, 357 women), mean aged 74.8±5.6 years. Thirty-one patients (5.8%) had pathological WST and 34 (6.4%) reported EAT-10 ≥3. There were significant differences (P<0.001) between groups (pathological WST vs. normal WST) in terms of all EAT-10 total scores. EAT-10 reported a high specificity (96.8% if ≥3 and 98.4% if ≥4), but a low sensitivity (58.1% if ≥3 and 54.8% if ≥4).

CONCLUSIONS

EAT-10 might be considered as useful screening tools for dysphagia in older people, considering the high specificity of EAT-10≥4.

CLINICAL REHABILITATION IMPACT

Screening dysphagia risk should be recommended also in patients undergoing rehabilitation in order to set up an early diagnosis and management.

Surgical treatment of epiglottis collapse in obstructive sleep apnoea syndrome: epiglottis stiffening operation

The epiglottis is an important structure that was largely ignored in early research on obstructive sleep apnoea/hypopnoea syndrome (OSAHS). Primary epiglottis collapse (EC) in patients with OSAHS is difficult to treat with conservative therapies, such as oral appliances and CPAP. Therefore, surgical treatment may represent a good option when dealing with EC, although up to now no standardised surgical procedures have been described. Herein, we describe a new surgical procedure that we called “epiglottis stiffening operation” (ESO); the technique is safe, devoid of complications, easy to perform and is effective in treatment of primary EC, which presents as a single or coexistent site of upper airway obstruction without altering fundamental functions of the epiglottis.

Self-reported Swallowing and Nutrition Status in Community-Living Older Adults

More New Zealanders are forecast to grow older in the community, ranging in levels of abilities and needs. Many health conditions can affect swallowing function or nutrition status in older age. However, older adults may not be aware of risk factors and when to seek help. A nationwide survey was conducted of self-reported swallowing ability and nutrition status in community-living New Zealanders aged 65 years and older to assess whether undisclosed swallowing and nutrition problems exist. Respondents completed an amalgamated questionnaire including two validated screening tools: Eating Assessment Tool (EAT-10) and Seniors in the Community: Risk Evaluation for Eating and Nutrition (SCREEN-II). A convenience sample of 1020 adults aged 65-96 years old was obtained. Mean EAT-10 score was 2.15 (SD = 4.3); 22.1% scored above the normative score (3 or more). Mean SCREEN-II score was 48.50 (SD = 6.5); 46.9% scored below normal (< 50 for adults under 85 years old, < 49 for adults over 84 years old). EAT-10 scores significantly correlated with SCREEN-II scores (p < 0.001). Scores did not correlate with age or differ between age groups. Significantly more respondents with medical history associated with dysphagia disclosed swallowing and nutrition problems (p < 0.001). This data suggest increased prevalence of swallowing difficulties in older age is attributed to health conditions and medications, rather than ageing itself. Swallowing complaints from community-living older adults should not be ignored or attributed to the normal ageing process. This study supports routine nutrition screening in older adults.

Dysphagia In Multiple Sclerosis Patients: Diagnostic And Evaluation Strategies

Dysphagia after multiple sclerosis (MS) is a common disabling symptom which can lead to serious complications. Regular screening and assessment of dysphagia in patients with MS are important. Using valid and reliable instruments to measure dysphagia in MS patients is a crucial component in clinical practice and of research quality. There are various strategies to diagnose and assess the dysphagia in patients with MS. Screening strategies are for early diagnosis of the dysphagia. Clinical, non-instrumental strategies are used to verify the presence and to determine the severity and cause of dysphagia. Instrumental strategies are complementary to clinical examination to provide objective data on the various aspects of swallowing dysfunctions. This review revealed a few validated tools for dysphagia assessment in MS. The Dysphagia in Multiple Sclerosis Questionnaire (DYMUS) and the Mann Assessment of Swallowing Ability (MASA) are the only validated MS-specific dysphagia tools. Further development of valid and reliable MS-specific screening and assessment tools that can be administered rapidly and scored easily to detect dysphagia and evaluate clinical outcomes in adults with MS is imperative. Until then, validation and metric evaluation of the screening and assessment tools currently available are required.

Evaluating the Psychometric Properties of the Kannada Version of EAT 10

BACKGROUND

Eating Assessment Tool 10 is a symptom survey and has several advantages over other existing questionnaires. The instrument has also proven to be useful in establishing initial dysphagia symptom severity and to aid in measuring treatment outcomes. Due to its wide applicability, the instrument has been translated into several languages. The aim of the present study was to translate and validate the Kannada version of Eating Assessment Tool 10.

METHOD

88 individuals with dysphagia and equal number of healthy individuals filled the Kannada version of Eating Assessment Tool. Internal consistency and test-retest reproducibility were used for reliability testing. Validity was also established by comparing the scores of dysphagia patients and healthy controls.

RESULTS

The overall Cronbach's α for the tool was 0.9 indicating a good internal consistency. The internal consistency of each of the items was also high, and ranged 0.88 to 0.9. Twenty patients filled the questionnaire after a span of 48 h, and the ICC coefficient was found to be 0.89 indicating a high reliability. The control group has significantly lower scores for all scales when compared to the dysphagia group [t(174) = 78.41, p < 0.001].

CONCLUSION

The present study demonstrates that the Kannada version of EAT 10 has good internal consistency, test retest reliability, and concurrent validity. The results of the study also reveal that it is a reliable and valid tool for screening dysphagia population.

Responsiveness of the EAT-10 to Clinical Change in Head and Neck Cancer Patients with Dysphagia

Purpose: This retrospective study evaluated the external responsiveness of the Eating Assessment Tool-10 (EAT-10) to clinical changes in a single cohort (n = 105) treated with chemoradiotherapy (CRT) or radiotherapy (RT) for head-and-neck cancer.Method: Patients completed the EAT-10 four times: (I) Within two weeks of commencing (C)RT, (II) in the final week of (C)RT, (III) two weeks post-(C)RT and (IV) following discharge from speech-language pathology services. Data was compared to their oral intake status, using the Functional Oral Intake Scale (FOIS).Result: Using Cohen's d, changes in the EAT-10 and FOIS were comparable, however, a difference was observed at data-point IV. At data-points I, II and III, the EAT-10 had a strong negative correlation with the FOIS (Spearman's ρ= -0.81, -0.80 and -0.81 resp.). At data-point IV the correlation strength decreased (Spearman's ρ= -0.69). Fisher's Z transformation found no statistically significant correlation coefficient differences between data-points I, II and III. A significant difference in correlation was found between these data-points and data-point IV (p = 0.027; p = 0.039 and p = 0.022 resp.). A very high internal consistency was found (Cronbach's α > 0.95) for all data-points.Conclusion: This study's results indicate that the EAT-10 has weaknesses in the external responsiveness and has redundancy of its question items.

Prevalence of non-obstructive dysphagia in patients with heartburn and regurgitation

OBJECTIVE

Heartburn and regurgitation are the most common gastroesophageal reflux symptoms, and dysphagia could be a possible symptom. This investigation aimed to evaluate the prevalence of non-obstructive dysphagia in patients with heartburn and regurgitation.

METHODS

A total of 147 patients (age, 20-70 years; women, 72%) complaining of heartburn and regurgitation, without esophageal stricture, previous esophageal surgery, or other diseases, were evaluated. Twenty-seven patients had esophagitis. The Eating Assessment Tool (EAT-10) was employed to screen for dysphagia; EAT-10 is composed of 10 items, and the patients rate each item from 0 to 4 (0, no problems; 4, most severe symptom). Results of the 147 patients were compared with those of 417 healthy volunteers (women, 62%; control group) aged 20-68 years.

RESULTS

In the control group, only two (0.5%) had an EAT-10 score ≥5, which was chosen as the threshold to define dysphagia. EAT-10 scores ≥5 were found in 71 (48.3%) patients and in 55% of the patients with esophagitis and 47% of the patients without esophagitis. This finding indicates a relatively higher prevalence of perceived dysphagia in patients with heartburn and regurgitation and in patients with esophagitis. We also found a positive correlation between EAT-10 scores and the severity of gastroesophageal reflux symptoms based on the Velanovich scale.

CONCLUSION

In patients with heartburn and regurgitation symptoms, the prevalence of dysphagia was at least 48%, and has a positive correlation with the overall symptoms of gastroesophageal reflux.

A Comparison of Patient-Centered Outcome Measures to Evaluate Dysphagia and Dysphonia After Anterior Cervical Discectomy and Fusion

OF BACKGROUND DATA

Dysphagia and dysphonia are the most common complications after anterior cervical diskectomy and fusion (ACDF). No consensus system exists currently in the spine literature for the classification of these conditions postoperatively.

OBJECTIVE

The purpose of this analysis was to evaluate the validity and reliability of the Eating Assessment Tool (EAT-10) in the assessment of dysphagia when compared with the Bazaz score. A secondary goal was to assess the Voice Handicap Index (VHI-10) scores among patients following ACDF.

METHODS

Patients treated with ACDF (one, two, or three level) for cervical radiculopathy and/or cervical myelopathy at two tertiary hospitals were administered patient-reported outcome metrics preoperatively as well as at multiple time points postoperatively. The metrics administered included the EAT-10, VHI-10, Bazaz, Neck Disbability Index, and EuroQol Five Dimensions questionnaire (EQ-5D)/visual analog scale.

RESULTS

One hundred patients were included in this study. Eighty-nine percentage had a 1-year follow-up, and 100% had a 12-week follow-up. Mean Neck Disbability Index, EQ-5D, and EQ-visual analog scale scores all improved from baseline at both 6 months and 1 year postoperatively. Both the EAT-10 and VHI-10 demonstrated excellent internal reliability (α = 0.95 and α = 0.90, respectively). Analysis of variance of EAT-10 and VHI-10 scores by time point demonstrated a statistically significant relationship (P < 0.0001). The EAT-10 and VHI-10 scores were statistically greater on postoperative day 1 than at all other times (Tukey posthoc, P < 0.0001 and P < 0.004, respectively). Across all time points, 176 instances of clinically significant dysphagia (EAT-10 ≥ 3) were noted, 57 (32%) of which were classified as "None" on the Bazaz classification.

CONCLUSIONS

The EAT-10 score is an accurate measure for mild to severe dysphagia and better captured significant dysphagia that would have otherwise been missed when the Bazaz score is used. EAT-10 and VHI-10 are better measures of postoperative dysphagia and dysphonia than the current metrics used in spine surgery.

STUDY DESIGN

This was a prospective cohort study of consecutive patients.

Improvement of Swallowing Function After Surgical Treatment of Diffuse Idiopathic Skeletal Hyperostosis: Our Experience

OBJECTIVE

To investigate the swallowing improvement in patients who underwent a transcervical prevascular retrovisceral approach for symptomatic cervical diffuse idiopathic skeletal hyperostosis (DISH), by means of the 10-item Eating Assessment Tool (EAT-10) questionnaire.

METHODS

Retrospective observational study of 21 patients treated with a transcervical anterior prevascular retrovisceral approach for symptomatic DISH with dysphagia as the primary symptom. All patients underwent videofluoroscopic study of swallowing before surgery and the EAT-10 questionnaire before and after the surgical procedure.

RESULTS

A statistically significant (P < 0.001) improvement in the postoperative EAT-10 score was reported. Sixteen out of 21 patients (76.2%) had their symptoms completely resolved, with an EAT-10 score less than 3. These results were not influenced by age and sex nor by presence of tracheostomy. The preoperative EAT-10 score was consistently related to postoperative outcome. Patients with mild and moderate dysphagia had better Δ in EAT-10 scores than patients with severe and very severe dysphagia (P = 0.02).

CONCLUSIONS

Surgical management seems to be effective in resolving swallowing disorders related to this disease in a consistent percentage of patients. This evidence is supported by the statistically significant improvement in EAT-10 scores after treatment. Moreover, it might be postulated that early intervention can guarantee a higher success rate because patients with severe and very severe dysphagia had significantly smaller improvement.

Assessment of swallowing function with oro-pharyngeal-esophageal scintigraphy in patients with idiopathic inflammatory myopathies

BACKGROUND

Swallowing impairment is frequently present in patients with idiopathic inflammatory myopathies (IIMs), and it represents an important cause of morbidity, dramatically reducing the quality of life of patients. Moreover, dysphagia is associated to a worst prognosis. Unfortunately, no standardized instrumental techniques for the assessment of the upper gastrointestinal tract in IIM patients are available. In this study, we explored the characteristics of the alterations in the upper gastrointestinal tract using oro-pharyngeal-esophageal scintigraphy (OPES) in a cohort of IIM patients and we correlated the alterations with clinical parameters.

METHODS

A total of 51 IIM patients were examined with OPES, both with liquids and semisolids, and the data acquired were examined to compute the transit time and the percentage of retention at oral, pharyngeal, and esophageal level. Patient-reported outcome data (PRO) on dysphagia, disease activity, and clinical parameters were collected.

KEY RESULTS

Oro-pharyngeal-esophageal scintigraphy identified at least one alteration in all patients, particularly with the semisolid test and oral and pharyngeal levels presented a higher frequency of involvement compared to the esophageal tract (P < 0.05). A very good correlation between dysphagia severity assessed by PRO and many OPES results was identified. In patients with a shorter disease duration, there was a higher prevalence of alterations at the oral and pharyngeal level and they were correlated to higher swallowing difficulties and higher disease activity parameters.

CONCLUSIONS & INFERENCES

Our results showed that OPES may represent a novel reproducible tool to assess dysphagia in IIM patients, thus opening new possibilities to evaluate dysphagia in these patients.

Validity and reliability of the French version of Eating Assessment Tool (EAT-10)

OBJECTIVE

To develop a French version of the Eating Assessment Tool (Fr EAT-10) and to assess its internal consistency, reliability and clinical validity.

METHODS

Fifty-six patients referred in the Swallowing Clinics of CHU Saint-Pierre Hospital (Brussels) and EpiCURA hospital (Ath, Belgium) for dysphagia were enrolled and completed fiberoptic endoscopic evaluation of swallowing and videofluoroscopy. Seventy-three asymptomatic subjects were included in the study. To assess reliability, Fr-EAT-10 was completed twice within a 7-day period. Validity was assessed by comparing Fr-EAT-10 scores with the scores of dysphagia handicap index (DHI) in all individuals. Normative value of EAT-10 was calculated and the receiver operating characteristic (ROC) curve was used to determine the best Fr-EAT-10 threshold associated with aspiration.

RESULTS

Fifty-two patients completed the study. Cronbach's alpha was 0.95 indicating a high internal consistency. Test-retest reliability was high in the entire cohort (r_s = 0.921). The correlation between Fr-EAT-10 total scores and DHI was high (r_s = 0.827) indicating a high external validity. Patients had a significant higher score of Fr-EAT-10 than the controls (p < 0.001) exhibiting a high internal validity. The analysis of normative data reported that a score of Fr-EAT-10 > 3 should be considered as abnormal. The correlation between Fr-EAT-10 and the occurrence of aspiration is significant (r_s = 0.327, p < 0.05). According to the ROC curve; aspirations need to be highly suspected for patients with Fr-EAT-10 ≥ 17.

CONCLUSION

The Fr-EAT-10 developed in this study is a reliable and valid self-administered tool in the evaluation of dysphagia in French-speaking patients.
