Development and preliminary validation of a patient-reported outcome measure for swallowing after total laryngectomy (SOAL questionnaire)

Swallowing after total laryngectomy surgery: where are we after 150 years?

Purpose of review

Recent findings

Dysphagia is a common sequela following total laryngectomy surgery; however, there is significant variability in its assessment and management. Manometry enables an accurate understanding of the underlying mechanism of dysphagia and precise assessment of any oesophageal dysfunction. EndoFLIP is a useful tool to better understand dysfunction of the upper oesophageal sphincter particularly to detect stricture.

Summary

Following total laryngectomy surgery, dysphagia is common; clinicians need to be alert to early indicators of dysfunction and understand the tools to comprehensively characterize swallow function. Accurate diagnosis of a stricture is important, as this aspect of dysfunction can be modified, and may alleviate surrogate problems such as a leaking voice prosthesis. Clinicians should have a low threshold to examine patients for oesophageal dysfunction due to the high prevalence of dysmotility following a laryngectomy.

Patient-reported outcome measures for dysphagia in head and neck cancer: A systematic review and appraisal of content validity and internal structure

Dysphagia is a major head and neck cancer (HNC) issue. Dysphagia-related patient-reported outcome measures (PROMs) are critical for patient-centred assessment and intervention tailoring. This systematic review aimed to derive a comprehensive inventory of HNC dysphagia PROMs and appraise their content validity and internal structure. Six electronic databases were searched to February 2023 for studies detailing PROM content validity or internal structure. Eligible PROMs were those developed or validated for HNC, with ≥20% of items related to swallowing. Two independent raters screened citations and full-text articles. Critical appraisal followed COSMIN guidelines. Overall, 114 studies were included, yielding 39 PROMs (17 dysphagia-specific and 22 generic). Of included studies, 33 addressed PROM content validity and 78 internal structure. Of all PROMs, only the SOAL met COSMIN standards for both sufficient content validity and internal structure. Notably, the development of 18 PROMs predated the publication of COSMIN standards. In conclusion, this review identified 39 PROMs addressing dysphagia in HNC, of which only one met COSMIN quality criteria. Given that half of PROMs were developed prior to COSMIN guidelines, future application of current standards is needed to establish their psychometric quality.

Prophylactic pectoralis major flap to compensate for increased risk of pharyngocutaneous fistula in laryngectomy patients with low skeletal muscle mass (PECTORALIS): study protocol for a randomized controlled trial

BACKGROUND

Total laryngectomy (TL) is a surgical procedure commonly performed on patients with advanced laryngeal or hypopharyngeal carcinoma. One of the most common postoperative complications following TL is the development of a pharyngocutaneous fistula (PCF), characterized by a communication between the neopharynx and the skin. PCF can lead to extended hospital stays, delayed oral feeding, and compromised quality of life. The use of a myofascial pectoralis major flap (PMMF) as an onlay technique during pharyngeal closure has shown potential in reducing PCF rates in high risk patients for development of PCF such as patients undergoing TL after chemoradiation and low skeletal muscle mass (SMM). Its impact on various functional outcomes, such as shoulder and neck function, swallowing function, and voice quality, remains less explored. This study aims to investigate the effectiveness of PMMF in reducing PCF rates in patients with low SMM and its potential consequences on patient well-being.

METHODS

This multicenter study adopts a randomized clinical trial (RCT) design and is funded by the Dutch Cancer Society. Eligible patients for TL, aged ≥ 18 years, mentally competent, and proficient in Dutch, will be enrolled. One hundred and twenty eight patients with low SMM will be centrally randomized to receive TL with or without PMMF, while those without low SMM will undergo standard TL. Primary outcome measurement involves assessing PCF rates within 30 days post-TL. Secondary objectives include evaluating quality of life, shoulder and neck function, swallowing function, and voice quality using standardized questionnaires and functional tests. Data will be collected through electronic patient records.

DISCUSSION

This study's significance lies in its exploration of the potential benefits of using PMMF as an onlay technique during pharyngeal closure to reduce PCF rates in TL patients with low SMM. By assessing various functional outcomes, the study aims to provide a comprehensive understanding of the impact of PMMF deployment. The anticipated results will contribute valuable insights into optimizing surgical techniques to enhance patient outcomes and inform future treatment strategies for TL patients.

Expert Consensus Statement: Management of Dysphagia in Head and Neck Cancer Patients

OBJECTIVE

To develop an expert consensus statement (ECS) on the management of dysphagia in head and neck cancer (HNC) patients to address controversies and offer opportunities for quality improvement. Dysphagia in HNC was defined as swallowing impairment in patients with cancers of the nasal cavity, paranasal sinuses, nasopharynx, oral cavity, oropharynx, larynx, or hypopharynx.

METHODS

Development group members with expertise in dysphagia followed established guidelines for developing ECS. A professional search strategist systematically reviewed the literature, and the best available evidence was used to compose consensus statements targeted at providers managing dysphagia in adult HNC populations. The development group prioritized topics where there was significant practice variation and topics that would improve the quality of HNC patient care if consensus were possible.

RESULTS

The development group identified 60 candidate consensus statements, based on 75 initial proposed topics and questions, that focused on addressing the following high yield topics: (1) risk factors, (2) screening, (3) evaluation, (4) prevention, (5) interventions, and (6) surveillance. After 2 iterations of the Delphi survey and the removal of duplicative statements, 48 statements met the standardized definition for consensus; 12 statements were designated as no consensus.

CONCLUSION

Expert consensus was achieved for 48 statements pertaining to risk factors, screening, evaluation, prevention, intervention, and surveillance for dysphagia in HNC patients. Clinicians can use these statements to improve quality of care, inform policy and protocols, and appreciate areas where there is no consensus. Future research, ideally randomized controlled trials, is warranted to address additional controversies related to dysphagia in HNC patients.

Swallowing outcomes following division of pseudo-epiglottis resulting from vertical pharyngeal closure in laryngectomy

BACKGROUND

Vertical closure of the pharynx after laryngectomy can result in an outpouch of the anterior wall of the neopharynx below the tongue base, called a pseudo-diverticulum. The prolapsed mucosa that separates the rest of the neopharynx from the pseudo-diverticulum is termed a pseudo-epiglottis.

METHODS

Prospective study of patients with pseudo-epiglottis. M. D. Anderson Dysphagia Inventory (MDADI) scores were used to assess swallowing outcomes pre- and post-pseudo-epiglottis division, including minimally clinically important difference (MCID) assessment.

RESULTS

Of 16 patients with a pseudo-epiglottis, 12 had dysphagia (75%). Symptomatic patients had significantly worse global MDADI and subscale scores. After division, the mean composite MDADI increased from 48.3 to 64.7 (p = 0.035), including a high MCID (16.4) with a similar improvement in the global question rating findings (31.1 vs. 60, p = 0.021). The MCID was significant for all MDADI subscales.

CONCLUSIONS

Pseudo-epiglottis formation is associated with significantly worse global and subscale MDADI scores. A clinically- and statistically-significant improvement in the MDADI scores was found following surgical division.

Dysphagia Advances in Head and Neck Cancer

Purpose of Review

This review summarises the current literature regarding head and neck cancer-associated dysphagia. Up-to-date evidence for dysphagia outcome measurement for this population is provided, in addition to recent innovations that aim to prevent, reduce or remediate the common and debilitating side effects of treatment.

Recent Findings

Both patient-reported outcomes and clinical measures are necessary to capture the multi-dimensional nature of swallowing. A minimally important difference in scores has been calculated for some of these measures, to aid interpretation and powering of clinical trials. The number of dysphagia-related trials has increased, predominantly investigating optimal treatment for oropharyngeal HPV-positive disease, and speech and language pathology interventions using an impairment-based approach.

Summary

Although substantial progress has been made, further work is necessary to establish a consensus over outcome measures. Modifying treatments may improve outcomes. Several trials are underway to establish the effectiveness of speech and language pathology dysphagia interventions.

Research progress in the risk factors and screening assessment of dysphagia in the elderly

With the aging of the population, the incidence of dysphagia has gradually increased and become a major clinical and public health issue. Early screening of dysphagia in high-risk populations is crucial to identify the risk factors of dysphagia and carry out effective interventions and health management in advance. In this study, the current epidemiology, hazards, risk factors, preventive, and therapeutic measures of dysphagia were comprehensively reviewed, and a literature review of screening instruments commonly used globally was conducted, focusing on their intended populations, main indicators, descriptions, and characteristics. According to analysis and research in the current study, previous studies of dysphagia were predominantly conducted in inpatients, and there are few investigations and screenings on the incidence and influencing factors of dysphagia in the community-dwelling elderly and of dysphagia developing in the natural aging process. Moreover, there are no unified, simple, economical, practical, safe, and easy-to-administer screening tools and evaluation standards for dysphagia in the elderly. It is imperative to focus on dysphagia in the community-dwelling elderly, develop unified screening and assessment tools, and establish an early warning model of risks and a dietary structure model for dysphagia in the community-dwelling elderly.

Conformity between modified Swallowing Outcome After Laryngectomy questionnaire and Flexible Endoscopic Evaluation of Swallowing in laryngeal carcinoma patients after total laryngectomy

BACKGROUND

One of the impacts in anatomic laryngeal and phariyngeal changes after total laryngectomy (TL) is oropharyngeal dysphagia (OPD). The detection of neopharyngeal residue as a sign of OPD can be performed by videofluoroscopy (VFS) and flexible endoscopic evaluation of swallowing (FEES). The availability of these tools in rural areas is still limited, thus the treatment of OPD is not maximal. There is a need for a more practical tool, including the modified swallowing outcomes after laryngectomy (SOAL) questionnaire.

METHODS

This was an analytic observational diagnostic study with a cross-sectional approach. Samples were obtained in Otorhinolaryngology Oncology Clinic and Outpatient Clinic of Dr. Soetomo General Academic Hospital, Surabaya, Indonesia, who filled SOAL modified questionnaire followed by FEES. Samples were obtained within 3 months from 10 May to 10 August 2021. The number of samples obtained through simple random sampling was 16 post-TL patients from a total population of 17 patients who met the inclusion and exclusion criteria. The conformity test between modified SOAL questionnaire and FEES was analyzed using McNemar comparison test and Kappa association test.

RESULTS

McNemar test showed no significant difference between both assessment tools (p > 0.05), and the Kappa test showed an association between both tools (p < 0.05). The results of this study stated that there was conformity between modified SOAL questionnaire and FEES in patients after TL in all types of food bolus had Kappa score of >0.81, showing a reliable association between these tools. Kappa test also showed that out of all three types of boluses, the soft bolus had the highest conformity with a Kappa score of 0.875, followed by thick bolus with 0.839, and watery bolus with 0.818.

CONCLUSION

There was a conformity between the results of the modified SOAL questionnaire and FEES in head and neck surgery patients after TL.

Swallowing Outcomes in Open Partial Horizontal Laryngectomy Type I and Endoscopic Supraglottic Laryngectomy: A Comparative Study

Background: Effective swallowing represents the main challenge in supraglottic laryngectomy. This study aimed to assess swallowing outcome comparing endoscopic supraglottic laryngectomy (ESL) and open partial horizontal laryngectomy type I (OPHL I). Methods: A retrospective study was carried out on 20 patients that underwent supraglottic laryngectomy from 2015 to 2021: 10 underwent ESL (group A) and 10 underwent OPHL I (Group B). Patients underwent fiberoptic endoscopic evaluation of swallowing (FEES) 3 months and 12 months after surgery and videofluoroscopy swallowing studies (VFSS) 12 months after surgery. A Swallowing Outcome After Laryngectomy (SOAL) questionnaire was administered to patients to assess their life quality. Results: A naso-gastric tube was placed in two patients of Group A and in all patients of Group B. Tracheostomy was performed in two patients of Group A and in all patients in Group B and it has been closed in 100% of them. According to Donzelli’s scale, FEES and VFSS showed better results in Group A at 3 months, while at 12 months they did not show statistically significant differences between ESL and OPHL I in terms of laryngeal penetration and aspiration. The SOAL questionnaire showed satisfactory life quality. Conclusion: Swallowing evaluation by FEES and VFSS did not demonstrate statistically significant differences at 12 months post-op between two surgeries, although ESL showed less cases of laryngeal penetration and aspiration at 3 months post-op. Anyway, good results of any surgery depend on careful patient selection and the surgeon’s experience.

Validity of functional patient-reported outcomes in head and neck oncology: A systematic review

Malignancy and treatment effects in head and neck oncology can be devastating to functional aspects of patient life such as swallowing, blinking, speech, salivation, and facial expression. Historically, the subjective nature of patient experience has resulted in difficulty with quantification and measurement of functional outcomes. Patient-Reported Outcomes (PROs) are questionnaires developed with patient input, forming the new gold standard for clinician assessment of subjective functional outcomes. The current review aims to identify and characterize the validation of PROs pertaining to four critical functional outcomes in head and neck oncology: swallowing, speech, dry mouth, and chewing. A literature search was conducted using MEDLINE, EMBASE, and the Cochrane databases for published, English language, peer-reviewed abstracts involving patients ≥ 18 years of age. Of 708 results, 705 were excluded at abstract or full text screening for not meeting inclusion criteria, exclusion of head and neck SCC patients in development, or absence of a functional domain measurement. The three reviewed studies-Xerostomia Questionnaire, Swallowing Outcomes After Laryngectomy, and Edmonton 33-exhibited strong reliability and construct and content validity, though two applied only to individual functional outcomes within specific patient populations receiving radiation or laryngectomy. While many PROs have been developed in head and neck oncology, very few properly employed extensive patient input in the development process. Further work must be committed to increasing head and neck cancer patient input in PRO development, particularly in the functional domains of speech and chewing.

Multiprofessional screening protocol for dysphagia in patients with HIV infection: elaboration and content validity

PURPOSE

To elaborate and validate a multiprofessional protocol to identify the risk of dysphagia in people with HIV at the time of hospitalization.

METHODS

After bibliographic review, the dysphagia screening protocol created was submitted to the analysis of HIV/ Aids expert judges and target audience in the application of this instrument to perform content validity. These evaluators could suggest changes to the protocol, judging clarity, pertinence, and comprehensiveness. The CVI 0.78 was used to confirm the validity of the results.

RESULTS

The protocol was created including aspects related to oral and pharyngeal swallowing, and the final score was calculated based on the risks for clinical complications. The instrument presented CVI above 0.78 for all items in the two validation phases, as well as total CVI of 0.92.

CONCLUSION

Based on the obtained data, it was possible to create and validate the screening protocol from the point of view of appearance and content, once it presented total CVI above the minimum value stipulated in the validation of the expert judges and the target public, obtaining an adequate result for the protocol. Therefore, we can consider the resolution instrument, with the capacity to fulfill what was proposed.

Translation and cross-cultural adaptation of the Swallow Outcomes After Laryngectomy (SOAL) Questionnaire for Brazilian Portuguese

PURPOSE

To adapt the Swallow Outcomes After Laryngectomy (SOAL) Questionnaire for the Brazilian culture.

METHOD

Validation study restricted to translation and cross-cultural adaptation. The following steps were taken: discussion of the need for the instrument in the Brazilian context, two independent translations, summary of the translations, analysis by a committee of 12 expert judges in dysphagia and oncology, analysis of the judges' comments and of the content validity indexes of each item and of the questionnaire as a whole, application of the questionnaire in a sample of 10 total laryngectomy patients, back translation and final summary.

RESULTS

It was necessary to perform semantic, syntactic/grammatical, experiential, idiomatic and content equivalences, mainly after the analysis by experts. The content validity indexes of each item and of the questionnaire were acceptable for all evaluated aspects. The back translation was equivalent to the original version. The comparison of the original, translated and back-translated versions indicated that the final version of the instrument was viable.

CONCLUSION

The SOAL was adapted to the Brazilian culture was developed. The validation process will continue using the version presented in this study.

European white paper: oropharyngeal dysphagia in head and neck cancer

PURPOSE

To develop a European White Paper document on oropharyngeal dysphagia (OD) in head and neck cancer (HNC). There are wide variations in the management of OD associated with HNC across Europe.

METHODS

Experts in the management of specific aspects of OD in HNC across Europe were delegated by their professional medical and multidisciplinary societies to contribute to this document. Evidence is based on systematic reviews, consensus-based position statements, and expert opinion.

RESULTS

Twenty-four sections on HNC-specific OD topics.

CONCLUSION

This European White Paper summarizes current best practice on management of OD in HNC, providing recommendations to support patients and health professionals. The body of literature and its level of evidence on diagnostics and treatment for OD in HNC remain poor. This is in the context of an expected increase in the prevalence of OD due to HNC in the near future. Contributing factors to increased prevalence include aging of our European population (including HNC patients) and an increase in human papillomavirus (HPV) related cancer, despite the introduction of HPV vaccination in various countries. We recommend timely implementation of OD screening in HNC patients while emphasizing the need for robust scientific research on the treatment of OD in HNC. Meanwhile, its management remains a challenge for European professional associations and policymakers.

Development of the Pediatric Dysphagia Risk Screening Instrument (PDRSI)

OBJETIVO

Desenvolver um instrumento de rastreio para a identificação de crianças com risco para disfagia, em ambiente hospitalar.

MÉTODO

O Instrumento de Rastreio para o Risco de Disfagia Pediátrica (IRRD-Ped), constituído por 23 questões, foi desenvolvido por fonoaudiólogos, após revisão da literatura. Ele foi proposto para ser aplicado aos responsáveis por crianças em internação hospitalar. O IRRD-Ped foi enviado a juízes para análise, tendo sido também realizado um estudo piloto. Para verificar a validade de critério, aplicou-se o IRRD-Ped aos responsáveis por crianças internadas e, posteriormente, realizou-se, com estas crianças, avaliação clínica da deglutição, através do Protocolo de Avaliação da Disfagia Pediátrica (PAD-PED). Os responsáveis assinaram o Termo de Consentimento Livre e Esclarecido. Os sujeitos foram separados em dois grupos (com disfagia e com deglutição normal), sendo verificada a associação entre as questões do IRRD-Ped e o resultado do PAD-PED, através do teste qui-quadrado de Person ou exato de Fisher. Definiu-se o ponto de corte para presença de risco para disfagia através da Curva ROC. A confiabilidade do IRRD-Ped foi verificada pelo coeficiente α de Cronbach.

RESULTADOS

A amostra foi constituída por 40 crianças com mediana de idade de 3,7 meses. Verificou-se associação estatisticamente significativa em oito itens do instrumento. A consistência interna do IRRD-Ped foi de 0,828. O ponto de corte para o risco de disfagia foi de cinco pontos (sensibilidade = 100% e especificidade = 80%).

CONCLUSÃO

Devido aos satisfatórios resultados encontrados, deve-se dar prosseguimento ao processo de validação do IRRD-Ped.

Factors affecting swallowing outcomes after total laryngectomy: Participant self-report using the swallowing outcomes after laryngectomy questionnaire

BACKGROUND

Little is known about what factors affect patient-reported swallowing outcome after total laryngectomy. We explored whether patient demographics, surgical variables, use of adjuvant treatment, and time since surgery were associated with patient-reported swallowing outcome.

METHODS

Cross-sectional study of laryngectomees in eight UK hospitals. Demographic, treatment, and surgical variables were drawn from medical notes. The swallowing outcomes after laryngectomy (SOAL) questionnaire captured perceived swallowing outcome.

RESULTS

Two hundred and twenty one participants had complete data on treatment-related variables. In regression analysis, having a free jejunum flap repair and requiring chemoradiation were the only two variables that added significantly to the model of worse self-reported swallowing outcome (R² adjusted = .23, P < .001).

CONCLUSION

The SOAL is a sensitive measure of self-reported swallowing outcome after laryngectomy. Type of surgical closure and the type of additional treatment influenced the swallowing outcome reported by patients. Changes in perceived swallowing function need to be routinely evaluated to inform clinical decision-making and intervention.

Effectiveness of a guided self-help exercise program tailored to patients treated with total laryngectomy: Results of a multi-center randomized controlled trial

OBJECTIVE

To investigate the effectiveness of a guided self-help exercise program on swallowing, speech, and shoulder problems in patients treated with total laryngectomy (TL).

MATERIALS AND METHODS

This randomized controlled trial included patients treated with TL in the last 5 years. Patients were randomized into the intervention group (self-help exercise program with flexibility, range-of-motion and lymphedema exercises and self-care education program) or control group (self-care education program). Both groups completed measurements before and 3 and 6-months after randomization. The primary outcome was swallowing problems (SWAL-QOL). Secondary outcomes were speech problems (SHI), shoulder problems (SDQ), self-management (patient activation: PAM) and health-related quality of life (HRQOL: EORTC QLQ-C30/H&N35). Adherence was defined as moderate-high in case a patient exercised >1 per day. Linear mixed model analyses were conducted to investigate the effectiveness of the intervention and to investigate whether neck dissection, treatment indication (primary/salvage TL), time since treatment, severity of problems, and preferred format (online/booklet) moderated the effectiveness.

RESULTS

Moderate-high adherence to the exercise program was 59%. The intervention group (n = 46) reported less swallowing and communication problems over time compared to the control group (n = 46) (p-value = 0.013 and 0.004). No difference was found on speech, shoulder problems, patient activation and HRQOL. Time since treatment moderated the effectiveness on speech problems (p-value = 0.025): patients within 6 months after surgery benefitted most from the intervention. Being treated with a neck dissection, treatment indication, severity of problems and format did not moderate the effectiveness.

CONCLUSION

The guided self-help exercise program improves swallowing and communication.

Validity Evidence of an Epidemiological Oropharyngeal Dysphagia Screening Questionnaire for Older Adults

OBJECTIVE

This research aimed to identify evidence of validity of a self-reported Oropharyngeal Dysphagia screening questionnaire for older adults based on test content, response processes, internal structure, relations to other variables, and reliability.

METHOD

This is a nonrandomized, cross-sectional study employing the concepts and principles of the Standards for Educational and Psychological Testing. Data were collected from 644 community-dwelling older adults (both genders, age: ≥60 years) who agreed to participate in some steps of the validation process. Statistical methods obtained the content representation of the construct, internal structure validation, discriminant and convergent evidence, and reliability, using a 5% significance level.

RESULTS

The screening tool was re-specified in nine questions that provided the best fit and robust reliability, with proper discriminant and convergent evidence.

CONCLUSIONS

The screening questionnaire presented valid and reliable results to identify oropharyngeal dysphagia symptoms in older adults, highlighting the importance of the validation process based on the standards to construct an epidemiological instrument.

The requirement for a disease-specific patient-reported outcome measure of dysphagia in oculopharyngeal muscular dystrophy

INTRODUCTION

There is no patient-reported outcome (PRO) questionnaire specifically designed to assess oropharyngeal dysphagia in oculopharyngeal muscular dystrophy (OPMD). To select a suitable questionnaire, content validity of the existing questionnaires must be assessed. This study sought (1) to identify dysphagia-related symptoms in OPMD and (2) to assess content validity of currently available PRO for the assessment of dysphagia severity in OPMD.

METHODS

A two-step literature review was conducted of dysphagia-related symptom identification and oropharyngeal dysphagia-related PRO. Symptoms were validated with an expert panel by using a Delphi survey. Content validity of PRO questionnaires was documented through content analysis.

RESULTS

Ten PRO questionnaires were identified. None of the questionnaires cover the entire symptom spectrum in OPMD and thus lack content validity.

DISCUSSION

The development and validation of a new PRO questionnaire to assess dysphagia in OPMD is required to establish the importance of symptomatic relief from new treatments. Muscle Nerve 59:445-450, 2019.

The prevalence of dysphonia and dysphagia in patients affected by immunomediated diseases and the role of psychometric tests

This cross-sectional investigation examined the prevalence and severity of dysphonia, globus pharyngeus, and dysphagia in patients affected by immunomediated (IM) diseases. Seventy subjects were administered the Voice Handicap Index (VHI) (scale 0-4), Glasgow-Edinburgh Throat Scale (GETS) (scale from 0 to 7) for globus pharyngeus assessment, and modified Swallowing Outcomes After Revised Laryngectomy (SOAL) (scale 0, 1, 2) to test swallowing symptoms. VHI: the mean percentage of answers with a score greater than 1 (corresponding to a frequency of situation's occurrence "sometimes," "almost always," or "always") was 25.7, 26.7, and 44.1% for functional, emotional, and physical groups of sub-items respectively. GETS: the mean percentage of answers with a score ≥ 3 was 60.85%, significantly higher if compared with that of answers with a score < 3 (40.14%). The mean percentages of answers with a score 0-2, 3-4, and 5-7 were 40.1, 16.7, and 43.7% respectively. SOAL: a mean of 57.9% of answers gained a symptomatic score (1 ["a little"] or 2 ["a lot"]) and 41.9%, the score 0. The difference was statistically significant (p < 0.05). The first two most recurrent items with a score 2 ("a lot") were "Do you have a problem swallowing dry food?" (46%) and "Do you have a problem swallowing solid food?" (36%). The study represents the first to describe the globus pharyngeus symptoms in IM population. Moreover, it allows to confirm the recurrence of dysphonia and dysphagia in this type of patients. Particularly, it has been demonstrated that the alteration of swallowing function is related to solid and dry food. The self-assessment questionnaires proved as a useful tool to early detection of dysfunctions in order to avoid further deterioration of quality of life and to prevent serious life-threatening complications.

Validation of the Hebrew Version of the Eating Assessment Tool-10 (H-EAT-10)

BACKGROUND AND OBJECTIVES

Dysphagia is a common disability with different etiologies. In order to measure dysphagia symptom severity and effects on quality of life, the Eating Assessment Tool (EAT-10) was developed and validated in the English language. We aimed to develop a Hebrew version of the EAT-10 and to evaluate its internal consistency, test-retest reliability, and validity in Hebrew-speaking adults with dysphagia.

SUBJECTS AND METHODS

The Hebrew EAT-10 (H-EAT-10) questionnaire was completed by 132 patients: 56 patients with dysphagia and 76 controls. Internal consistency analysis was calculated using Cronbach α, and test-retest reliability was calculated using intraclass correlation coefficient in order to assess clinical validity.

RESULTS

Internal consistency and test-retest reliability were found to be high in the H-EAT-10 (Cronbach α = 0.955 and intraclass correla tion = 0.98). In addition, H-EAT-10 scores in the dysphagia group were found to be significantly higher than those in the control group (p < 0.001).

CONCLUSION

This study demonstrated that H-EAT-10 is a reliable and valid tool that may be implemented for clinical practice and research on dysphagia in a Hebrew-speaking population.

Patient-reported outcome measures in dysphagia: a systematic review of instrument development and validation

OBJECTIVE

Patient-reported outcome (PRO) measures are commonly used to capture patient experience with dysphagia and to evaluate treatment effectiveness. Inappropriate application can lead to distorted results in clinical studies. A systematic review of the literature on dysphagia-related PRO measures was performed to (1) identify all currently available measures and (2) to evaluate each for the presence of important measurement properties that would affect their applicability.

DESIGN

MEDLINE via the PubMed interface, the Cumulative Index of Nursing and Allied Health Literature, and the Health and Psychosocial Instrument database were searched using relevant vocabulary terms and key terms related to PRO measures and dysphagia. Three independent investigators performed abstract and full text reviews. Each study meeting criteria was evaluated using an 18-item checklist developed a priori that assessed multiple domains: (1) conceptual model, (2) content validity, (3) reliability, (4) construct validity, (6) scoring and interpretation, and (7) burden and presentation.

RESULTS

Of 4950 abstracts reviewed, a total of 34 dysphagia-related PRO measures (publication year 1987-2014) met criteria for extraction and analysis. Several PRO measures were of high quality (MADS for achalasia, SWAL-QOL and SSQ for oropharyngeal dysphagia, PROMIS-GI for general dysphagia, EORTC-QLQ-OG25 for esophageal cancer, ROMP-swallowing for Parkinson's Disease, DSQ-EoE for eosinophilic esophagitis, and SOAL for total laryngectomy-related dysphagia). In all, 17 met at least one criterion per domain. Thematic deficiencies in current measures were evident including: (1) direct patient involvement in content development, (2) empirically justified dimensionality, (3) demonstrable responsiveness to change, (4) plan for interpreting missing responses, and (5) literacy level assessment.

CONCLUSION

This is the first comprehensive systematic review assessing developmental properties of all available dysphagia-related PRO measures. We identified several instruments with robust measurement properties in multiple diseases including achalasia, oropharyngeal dysphagia, post-surgical dysphagia, esophageal cancer, and dysphagia related to neurological diseases. Findings herein can assist clinicians and researchers in making more informed decisions in selecting the most fundamentally sound PRO measure for a given clinical, research, or quality initiative.

Validation and Cultural Adaptation of the Arabic Version of the Eating Assessment Tool (EAT-10)

BACKGROUND AND OBJECTIVES

The Eating Assessment Tool (EAT-10) is a 10-item self-administered questionnaire. It is a noninvasive tool to measure patients' perception of their swallowing problems. The purposes of the present study were to develop an Arabic version of the EAT-10 and to evaluate its validity, consistency, and reliability in the Arabic-speaking population with oropharyngeal dysphagia.

SETTING AND DESIGN

This was a prospective study carried out at the Communication and Swallowing Disorders Unit, King Saud University, Riyadh, Saudi Arabia.

SUBJECTS AND METHODS

The Arabic EAT-10 was administered to 138 patients with oropharyngeal dysphagia and 83 control subjects. Internal consistency and test-retest reliability were evaluated. Content and clinical validity were studied, and the EAT-10 results were compared across patients and control groups.

RESULTS

The Arabic EAT-10 showed excellent internal consistency (Cronbach's α = 0.92). Also, good test-retest reliability was found for the total scores of the Arabic EAT-10 (intraclass correlation = 0.73). There was a significant difference in Arabic EAT-10 scores between the oropharyngeal dysphagia group and the control group (p < 0.001).

CONCLUSION

This study demonstrated that the Arabic EAT-10 is a valid tool that can be used for screening of dysphagia-related problems in an Arabic-speaking population.

'What About Swallowing?' Diagnostic Performance of Daily Clinical Practice Compared with the Eating Assessment Tool-10

In daily clinical practice, patients are frequently asked about their swallowing as part of the patient-clinician interview. This study compares the diagnostic performance of a single open question ‘What about swallowing?’ (usual care) with the Eating Assessment Tool (EAT-10) as reference test in screening for oropharyngeal dysphagia (OD). 303 outpatients at risk of OD were recruited at three university hospitals: 162 men and 141 women with a mean age of 70 years. All data were retrieved by phone. To identify patients at risk of dysphagia, two different cut-off scores for the EAT-10 total score were retrieved from the literature. The diagnostic performance of the single question was determined by comparing dichotomized answers to the single question (no problems versus difficulties in swallowing) with the EAT-10 as reference test. Sensitivity, specificity, positive and negative predictive values ranged between 0.75–0.76, 0.75–0.84, 0.93–0.97 and 0.38–0.43, respectively. Mostly, the results of this exploratory study indicate a sufficient diagnostic performance of the single question in identifying patients who are at risk of dysphagia when using the EAT-10 questionnaire as a reference test. Further research, is, however, necessary to provide additional psychometric data on Functional Health Status (FHS) questionnaires including the single question using either FEES or VFS as gold standard or reference test.

Psychometric evaluation of the Swallowing Outcomes After Laryngectomy (SOAL) patient-reported outcome measure

BACKGROUND

The purpose of this study was to evaluate the psychometric properties of the Swallowing Outcomes After Laryngectomy (SOAL) in a large group of people who underwent a laryngectomy.

METHODS

We conducted a cross-sectional psychometric study of laryngectomy patients (minimum 3 months posttreatment) attending routine hospital follow-up for the psychometric evaluation of SOAL.

RESULTS

One hundred ten people participated in this study. Thirteen percent of the patients had a laryngectomy, 63% had laryngectomy with radiotherapy, and 24% had laryngectomy with chemoradiation therapy. The SOAL showed good quality of data (minimal missing data and floor effects); good internal consistency (α = 0.91); and adequate test-retest reliability (intra-class correlation coefficient = 0.73). In terms of validity, it differentiated people by treatment group (F(2,85) = 8.02; p = .001) and diet texture group (t(102) = -7.33; p < .001).

CONCLUSION

The SOAL demonstrates good validity and has potential for use in research. Further study is required to determine its clinical application. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1639-E1645, 2016.

Screening tools for dysphagia: a systematic review

Purpose:To perform a systematic review of screening instruments for dysphagia available in the literature.Methods:For the selection of studies, the following descriptors were used: "questionários", "questionnaires", "transtornos de deglutição", "deglutition disorders", "programas de rastreamento", and "mass screening". The online databases used for the research were Virtual Health Library (LILACS, IBECS, MEDLINE, Cochrane Library, SciELO) and PubMed. The research was performed from April to June 2013. Selection criteria articles in English, Portuguese, and Spanish, regardless of the year of publication, whose title, abstract, or text had any relation to the purpose of the research. After reading the articles in their entirety, identification data and method of the articles were extracted for later analysis.Results:The research carried out from the proposed descriptors produced 1,012 articles. After reviewing the titles, summaries, and fully reading the articles, 20 studies were chosen. The publications on instruments for the identification of dysphagic patients started in 1999, and 50% of the analyzed studies were carried out in the USA. The methods used on the instruments were questionnaires, observation of patient's clinical signals and symptoms, the request for execution of some orofacial movements, and swallowing test with water or food.Conclusion:Screening instruments in dysphagia are fairly heterogeneous and have been developed for different audiences with the main objective of identifying patients with swallowing disorders.

Psychometric properties of questionnaires on functional health status in oropharyngeal dysphagia: a systematic literature review

INTRODUCTION

Questionnaires on Functional Health Status (FHS) are part of the assessment of oropharyngeal dysphagia.

OBJECTIVE

To conduct a systematic review of the literature on the psychometric properties of English-language FHS questionnaires in adults with oropharyngeal dysphagia.

METHODS

A systematic search was performed using the electronic databases Pubmed and Embase. The psychometric properties of the questionnaires were determined based on the COSMIN taxonomy of measurement properties and definitions for health-related patient-reported outcomes and the COSMIN checklist using preset psychometric criteria.

RESULTS

Three questionnaires were included: the Eating Assessment Tool (EAT-10), the Swallowing Outcome after Laryngectomy (SOAL), and the Self-report Symptom Inventory. The Sydney Swallow Questionnaire (SSQ) proved to be identical to the Modified Self-report Symptom Inventory. All FHS questionnaires obtained poor overall methodological quality scores for most measurement properties.

CONCLUSIONS

The retrieved FHS questionnaires need psychometric reevaluation; if the overall methodological quality shows satisfactory improvement on most measurement properties, the use of the questionnaires in daily clinic and research can be justified. However, in case of insufficient validity and/or reliability scores, new FHS questionnaires need to be developed using and reporting on preestablished psychometric criteria as recommended in literature.
