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

Validation of the Swedish Eating Assessment Tool, S-EAT-10, for patients with head and neck cancer

The aim of this study was to validate the Swedish version of Eating Assessment Tool (S-EAT-10) for head and neck cancer patients. The participants (n = 60) had persistent swallowing difficulties 6-36 months after completion of curative radiotherapy. The videofluoroscopic swallowing study was assessed using the Penetration Aspiration Scale and the Yale Pharyngeal Residue Severity Rating Scale modified for videofluoroscopy. Participants completed questionnaires S-EAT-10, M.D. Anderson Dysphagia Inventory (MDADI) and study-specific questions. Internal consistency was excellent and the test-retest reliability was good. Regarding convergent validity, S-EAT-10 showed moderate to strong correlation with the MDADI and no to weak correlation with study-specific questions regarding meal duration and weight change. Regarding criterion validity, there was a weak correlation between S-EAT-10 and instrumental measures. S-EAT-10 showed 85% sensitivity in identifying patients with dysphagia. S-EAT-10 could not discriminate between different degrees of dysphagia. Thus, S-EAT-10 showed sufficient psychometric properties regarding head and neck cancer patients.

Validation and Reliability of the Polish Version of the Eating Assessment Tool-10 Questionnaire

Introduction: Early identification of patients at risk of dysphagia is of paramount importance. To date, no dysphagia screening questionnaire has been validated and translated into Polish that can be widely used in a multidisciplinary setting. Our study aimed to validate and adapt the Polish version of the Eating Assessment Tool-10 questionnaire (EAT-10). Materials and Methods: The EAT-10 questionnaire was translated into Polish using a formal forward-backward translation method. The Polish EAT-10 was administered to 109 patients with different dysphagia etiologies and 24 control subjects. Internal consistency, unidimensionality, test-retest reliability and external validity against the Visual Analog Scale (VAS), and Flexible Endoscopic Evaluation of Swallowing (FEES) were performed. Results: The EAT-10PL demonstrated excellent internal consistency (Cronbach's α = 0.958) and confirmed unidimensionality. We found a strong correlation between EAT-10PL with the Visual Analog Scale (VAS) (rs = 0.94, p < 0.001) and a weaker correlation with the PAS (rs = 0.55, p < 0.001). We reported a sensitivity of 79.5% and specificity at the level of 60.0%, using ≥3 as a cut-off point. The statistically chosen cutoff point for PAS ≥ 2 and EAT-10 ≥ 6 indicated optimal specificity (70.0%) and sensitivity (79.5%) of measurements performed using EAT-10PL. The EAT-10PL questionnaire demonstrates high discriminatory ability relative to the control group (F(4, 104) = 16.219, p < 0.001, η2 = 0.38 [95%CI: 0.22-0.48]). Conclusions: The Polish EAT-10 is a valid and reliable, self-administered questionnaire for dysphagic patient identification. The Polish EAT-10 ≥ 3 can be considered abnormal; however, it seems that EAT-10PL is not appropriate for patients with dysphagia and a chronic cough background, and further research is required.

Validity and Reliability of Dysphagia Outcome Severity Scale (DOSS) When Used to Rate Flexible Endoscopic Evaluations of Swallowing (FEES)

The Dysphagia Outcome and Severity Scale is used both clinically and within dysphagia research, internationally. Although it was developed using videofluoroscopic swallowing studies, it is frequently used to rate Flexible Endoscopic Evaluations of Swallowing. The validity and reliability of DOSS-use with FEES, however, has not previously been evaluated. This study investigated the validity and rater reliability of clinicians using DOSS to rate FEES. Eleven Speech-Language Pathologists (SLPs) with varied dysphagia experience were recruited to review and DOSS-rate 17 soundless FEES (198 bolus swallows) recorded from 11 heterogenic dysphagic patients (2 cases with repeat FEES) and 4 healthy adults. The SLPs DOSS-ratings were compared against the initial comprehensive dysphagia evaluation (including patient diagnosis, interview, cranial nerve and complete FEES assessment) with Functional Oral Intake Scale (FOIS) and DOSS outcome measures. The SLPs were blinded to patient details and comprehensive dysphagia examination. Re-randomised rating of FEES cases occurred two weeks later (intra rater reliability). Criterion validity for DOSS-ratings (compared against comprehensive dysphagia evaluation with FOIS and DOSS) were strong-very strong (rs = 0.858 and 0.936 respectively; p < 0.001). Inter rater reliability demonstrated high agreement (α = 0.891), also intra rater reliability demonstrated almost perfect agreement (Kw = 0.945). This study's results, with strong-very strong criterion validity and high rater reliability by SLPs, adds to the evidence for DOSS-use with FEES. Future validity research comparing DOSS with both FEES and VFSS simultaneously is recommended.

Improved health outcomes of nasopharyngeal carcinoma patients 3 years after treatment by the AI-assisted home enteral nutrition management

Objectives

Patients with nasopharyngeal carcinoma (NPC) are prone to malnutrition, which leads to deterioration of health. This study is to clarify the effect of Artificial intelligence (AI)-assisted home enteral nutrition (HEN) management mode on the health status of patients with stage III to stage IV NPC after 3 years of treatment, and to provide a new strategy for improving the quality of life of patients.

Methods

Patients with stage III ~ IV NPC were determined whether to accept AI-assisted HEN management according to voluntary principle. After 3 years of management, the survival rate, distant metastasis rate and local recurrence rate were counted, and the basic body quality, laboratory detection, eating difficulty score, mental health score and other examinations were performed on the surviving patients to evaluate the overall health status.

Results

The three-year survival rate of patients with NPC who received AI-assisted HEN management after treatment was improved. Various tests showed that AI-assisted HEN improved the nutritional intake of patients, had a low positive rate of Epstein-Barr virus, reduced adverse reactions such as psychological stress and physical pain, and could improve the quality of life of patients.

Conclusion

AI-assisted HEN has a positive auxiliary effect on clinical treatment, which is helpful to promote the recovery of patients with NPC.

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

BACKGROUND

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

OBJECTIVE

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

MATERIALS AND METHODS

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

RESULTS

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

CONCLUSIONS

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

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.

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.

Translation, and validation of Dysphagia Outcome and Severity Scale (DOSS): Swedish version

BACKGROUND

Swallowing dysfunction (dysphagia) significantly impacts patient and medical outcomes. In Sweden, there is no comprehensive outcome measure for dysphagia that incorporates holistic assessment and dysphagia impact on a person's impairment, function and participation. The Dysphagia Outcome and Severity Scale (DOSS) was developed and validated (in English) and incorporates the World Health Organisation's (WHO) aforementioned, International Classification of Functioning (ICF) aspects. This study translated then evaluated the validity and reliability of the Swedish version, DOSS-S.

METHOD

Translation occurred based on WHO recommendations. The Content Validity Index (CVI) of the translated version (DOSS-S) was assessed twice by 11 (multi-professional) dysphagia experts. Criterion validity and rater reliability was calculated using 18 Speech Pathologists assessing patient cases from International Dysphagia Diet Standardization Initiative-Functional Diet Scale (IDDS-FDS) research.

RESULTS

Very high CVI values (0.96-0.99) for the linguistic correlation, and high CVI values (0.84-0.94) for applicability correlation were achieved. High criterion validity of DOSS-S with IDDSI-FDS was demonstrated (rs = 0.89, p < 0.01), with very high inter and intra rater reliabilities (ICC > 0.90).

CONCLUSION

The DOSS-S demonstrated very high validity values, and very high inter and intra rater reliability. This research contributes to improved dysphagia management by providing interprofessional dysphagia clinicians with a validated scale to identify patient progression, communicate dysphagia status between regions and countries, and document patient outcomes using an ICF framework.

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.

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.

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.

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.
