Neurogenic Dysphagia: Systematic Review and Proposal of a Classification System.

OBJECTIVE: Introduction and validation of a phenotypic classification of neurogenic dysphagia based on flexible endoscopic evaluation of swallowing (FEES). METHODS: A systematic literature review was conducted, searching MEDLINE from inception to May 2020 for FEES findings in neurologic diseases of interest. Based on a retrospective analysis of FEES videos in neurologic diseases and considering the results from the review, a classification of neurogenic dysphagia was developed distinguishing different phenotypes. The classification was validated using 1,012 randomly selected FEES videos of patients with various neurologic disorders. Chi-square tests were used to compare the distribution of dysphagia phenotypes between the underlying neurologic disorders. RESULTS: A total of 159 articles were identified, of which 59 were included in the qualitative synthesis. Seven dysphagia phenotypes were identified: (1) "premature bolus spillage" and (2) "delayed swallowing reflex" occurred mainly in stroke, (3) "predominance of residue in the valleculae" was most common in Parkinson disease, (4) "predominance of residue in the piriform sinus" occurred only in myositis, motoneuron disease, and brainstem stroke, (5) "pharyngolaryngeal movement disorder" was found in atypical Parkinsonian syndromes and stroke, (6) "fatigable swallowing weakness" was common in myasthenia gravis, and (7) "complex disorder" with a heterogeneous dysphagia pattern was the leading mechanism in amyotrophic lateral sclerosis. The interrater reliability showed a strong agreement (kappa = 0.84). CONCLUSION: Neurogenic dysphagia is not a symptom, but a multietiologic syndrome with different phenotypic patterns depending on the underlying disease. Dysphagia phenotypes can facilitate differential diagnosis in patients with dysphagia of unclear etiology.

Classification of Stroke Patients With Dysphagia Into Subgroups Based on Patterns of Submental Muscle Strength and Skill Impairment.

OBJECTIVES: To identify and characterize subgroups of stroke patients with clinical signs of dysphagia, based on swallowing-related strength and skill impairments of the submental muscle group. DESIGN: Prospective observational study. SETTING: Inpatient rehabilitation centers and community dwellings. PARTICIPANTS: Individuals (N=114), including stroke patients with dysphagia (n=55) and 2 control groups including myopathic patients with dysphagia (n=19) and healthy volunteers (n=40) were included in this study. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Novel clinical assessment of strength (force generation) and skill (spatial and temporal precision of muscle activation) of the submental muscle group during swallowing and nonswallowing behaviors, using surface electromyography and dynamometry. RESULTS: Hierarchical cluster analysis revealed 4 clusters, which could be broadly characterized as cluster 1: intact strength and skill, cluster 2: poor strength and poor nonswallowing skill, cluster 3: poor strength, and cluster 4: poor strength and poor swallowing skill. Membership in cluster was significantly associated with medical diagnosis (P<.001). The majority of healthy and myopathic participants were assigned to clusters 1 and 3, respectively, whereas stroke patients were found in all 4 clusters. Skill outcome measures were more predictive of cluster assignment than strength measures. CONCLUSIONS: Although healthy and myopathic participants demonstrated predominantly homogeneous swallowing patterns of submental muscle function within their etiology, several subgroups were identified within stroke, possibly reflecting different subtypes of swallowing function. Future research should focus on the nature and rehabilitation needs of these subtypes. Assessment of skill in swallowing may be an important but overlooked aspect of rehabilitation.

The Gugging Swallowing Screen in dysphagia screening for patients with stroke: A systematic review.

BACKGROUND: Dysphagia in patients with stroke can cause serious complications, such as aspiration and pneumonia, that often lead to increase in mortality and length of hospitalization. Several screening tests for dysphagia have been developed and are used in clinical practice to prevent dysphagia complications. The Gugging Swallowing Screen is 1 such screening test. It is suggested for use in the assessment of the ability of patients to swallow fluid and non-fluid foods separately. It also promotes effective communication between healthcare providers. OBJECTIVES: We aimed to investigate the validity and benefit of the Gugging Swallowing Screen. DESIGN: This was a systematic review. DATA SOURCE: We sourced data from electronic databases including Ovid MEDLINE, Ovid EMBASE, the Cochrane Library, KoreaMed, Research Information Sharing Service, and Korean studies Information Service System. REVIEW METHODS: We conducted a systematic review of electronic databases. We included studies published in English and Korean up to November 2018 that pertained to the Gugging Swallowing Screen. We designed strategies that included Medical Subject Headings and keywords, such as "dysphagia," "swallowing," "assessment," "screening," and "GUSS," used alone or in combination. RESULTS: Of the 297 studies that appeared in the search result, 219 articles were reviewed by 2 independent reviewers after duplicate studies were eliminated. Finally, 8 articles were included in this study. With regard to validity, the Gugging Swallowing Screen had a pooled sensitivity of 0.97 (95% confidence interval: 0.93-0.99), a pooled specificity of 0.67 (95% confidence interval: 0.59-0.74), and an area under the receiver operating characteristic curve of 0.9381. With regard to benefit, early systematic dysphagia screening using Gugging Swallowing Screen performed by nurses reduced both screening time and pneumonia rate compared to the control group (p = 0.004). The incidence of X-ray-verified pneumonia was significantly lower in the Gugging Swallowing Screen group than in the clinical screening group (p ˂ 0.01), but no significant difference was observed in the incidence of pneumonia compared to the value predicted using the 10 mL water swallowing test. CONCLUSIONS: The Gugging Swallowing Screen is a reliable and sensitive tool for screening dysphagia. Early and systematic assessment can prevent aspiration and pneumonia. However, further studies are needed to confirm the effectiveness of this tool.

Neck Disability and Swallowing Function in Posttreatment Head and Neck Cancer Patients.

OBJECTIVE: To examine the relationship between symptoms of neck disability and swallowing dysfunction among head and neck cancer (HNC) survivors. STUDY DESIGN: Cross-sectional analysis. SETTING: Single-center, university-affiliated HNC survivorship clinic. SUBJECTS AND METHODS: Survivors' patient-reported symptoms of neck disability and swallowing dysfunction were prospectively collected from March 2017 to May 2018. Neck disability and swallowing dysfunction were measured using the Neck Disability Index and Eating Assessment Tool (EAT-10), respectively. Linear regression was used to analyze the association between neck disability and swallowing dysfunction. RESULTS: A total of 179 survivors, predominantly male (n = 130, 72.6%) with an average age of 64.64 ± 9.91 years, were included in the analysis. Primary cancer sites were oropharynx (n = 85, 47.5%), oral cavity (n = 59, 33.0%), and larynx/hypopharynx (n = 35, 19.5%). Mean EAT-10 score was 10.07 ± 10.89 (range = 0-40; >2 indicative of swallowing dysfunction). Survivors treated for early stage cancer had lower EAT-10 scores than those with advanced stage (early = 3.55 ± 7.46; advanced = 11.95 ± 11.02, P < .001). After controlling for age, time since treatment, American Joint Committee on Cancer stage, and treatment modality, the EAT-10 score for patients with mild neck disability was 6.88 (95% confidence interval [CI], 3.71-10.06; P < .001) points higher than those without neck disability, and the score for those with moderate-complete neck disability was 13.65 (95% CI, 9.47-17.83; P < .001) points higher than those without neck disability. CONCLUSIONS: Swallowing dysfunction is a commonly recognized effect of HNC treatment. The prevalence and burden of neck disability are shown to be highly correlated with swallowing dysfunction. These results support the need for comprehensive, multidisciplinary rehabilitation interventions for patients with HNC.

Clinical reasoning and hypothesis generation in expert clinical swallowing examinations.

BACKGROUND: A clinical swallow examination (CSE) provides integral information that informs the diagnostic decision-making process within dysphagia management. However, multiple studies have highlighted a high degree of reported variability within the CSE process. It has been hypothesized that such variability may be the result of the clinical reasoning process rather than poor practices. AIMS: To elucidate the nature of expert, speech-language therapists' (SLTs) clinical reasoning during an initial bedside assessment of patients referred for suspected dysphagia in the acute care environment. METHODS & PROCEDURES: An exploratory 'observation of practice' qualitative methodology was used to achieve the aim. Four expert SLTs, from two clinical services, completed CSEs with 10 new referrals for suspected dysphagia. All assessments were video-recorded, and within 30 min of completing the CSE, a video-stimulated 'think aloud' semi-structured interview was conducted in which the SLT was prompted to articulate their clinical reasoning at each stage of the CSE. Three types of concept maps were generated based on this video and interview content: a descriptive concept map, a reasoning map and a hypothesis map. Patterns that consistently characterized the assessment process were identified, including the overall structure; types of reasoning (inductive versus deductive), facts (i.e., clinical information) drawn upon; and outcomes of the process (diagnosis and recommendations). Interview content was examined to identify types of expert reasoning strategies using during the CSE. OUTCOMES & RESULTS: SLTs' approach to clinical assessment followed a consistent structure, with data gathered pre-bedside, during the patient interview and direct assessment before a management recommendation was made. Within this structure, SLTs engaged in an iterative approach with inductive hypothesis-generating and deductive hypothesis-testing, with each decision-making pathway individually tailored and informed by patient-specific facts collected during the assessment. Clinical assessment was primarily geared towards management of an initial acute presentation with less focus on formulating a diagnostic statement. CONCLUSIONS & IMPLICATIONS: Variability in reported dysphagia practice is likely the result of a patient-centred assessment process characterized by iterative cycles of fact-gathering in order to generate and test clinical hypotheses. This has implications for the development of novel assessment tools, as well as professional development and education of novice SLTs. What this paper adds What is already known on the subject CSE practices are reportedly variable, which has led to calls for more stringent, standardized assessment tools. Emerging evidence suggests that this variation is non-random, but may arise from clinical reasoning processes. What this paper adds to existing knowledge We directly observed expert SLTs conducting CSEs and identified patterns in practice that were consistent across all CSEs evaluated. These patterns were consistent in structure, whereas the content of the assessment items varied and was tailored to individual patient presentation. Overall, expert SLTs engaged in balanced cycles of inductive hypothesis generation and deductive hypothesis-testing, a hallmark of good clinical assessment and practice. What are the potential or actual clinical implications of this work? Ensuring quality CSE requires a more nuanced approach that considers the role of clinical reasoning in SLTs' decision-making and the potential unintended negative consequences of standardized assessment tools.

Manejo hospitalario de la persona mayor con disfagia / Clinical management of elderly with dysphagia

La disfagia es la alteración de la seguridad y eficacia del proceso deglutorio que dificulta el correcto paso del alimento/saliva desde la boca hacia el estómago, lo que aumenta la probabilidad de desnutrición, deshidratación y aspiración pulmonar con un consiguiente empeoramiento del pronóstico[1]. Los cambios en el acto de tragar relacionados con la edad se llaman presbifagia[6], un cuadro altamente prevalente afectando entre 13-30% de las personas mayores autovalentes, e incrementando considerablemente, en contexto de hospitalización, al 30-47% por causas adicionales[7]: mecánicas, neurológicas o iatrogénicas, que potencian las complicaciones o desestabilizan el equilibrio deglutorio. Recientemente la disfagia se considera un síndrome geriátrico[6], lo que conlleva desafíos para el equipo multidisciplinario respecto de prevenir y disminuir efectos adversos[8]. El conflicto principal, es que para el equipo hospitalario resulta un desafío detectar a personas mayores con riesgo aspirativo, por lo que no son identificados a tiempo[6­8]. El objetivo de este artículo es exponer un esquema multidisciplinario de detección de riesgo aspirativo en contexto de hospitalización de la "Unidad Especializada de Cuidado en persona Mayor" (UCAM) de Clínica Las Condes, para lo cual, primero se revisa literatura asociada a disfagia, clasificación reciente, consecuencias, métodos de evaluación recomendados y condiciones específicas, asociadas a riesgo aspirativo y segundo, se definen dos vías junto con Geriatría, Enfermería y Nutrición: 1) Se definen criterios de derivación fonoaudiológica oportunos para evaluación clínica de la deglución, y 2) Método precoz de pesquizaje y evaluación multidisciplinario de disfagia orofaríngea y riesgo aspiratorio.

Dysphagia is the alteration of the safety and efficacy of the swallowing process that prevents the correct transit of food/saliva from the mouth to the stomach, which increases malnutrition, dehydration and pulmonary aspiration and patient's bad prognosis[1]. The changes in the act of swallowing related to age are called presbyophagy[6]. A highly prevalent affect of self-worthy elderly people (between 13-30%), and increasing considerably in hospitalization context (30-47%) for additional causes[7]: mechanical, neurological or iatrogenic, which increases complications or destabilizes swallowing balance. Recently dysphagia it is considered a geriatric syndrome[6], that challenges the multidisciplinary team regarding prevention and reduction of adverse effects related to hospitalization units of elderly people[8]. One of the main tasks of the healthcare team is the early detection of elderly people with aspiration risk. The objective of this article is present a multidisciplinary protocol of EP with dysphagia in the context of hospitalization in the "Specialized care unit for the elderly" (SCUE) of Clínica Las Condes. Initially, literature associated with oropharyngeal dysphagia (OD), recent classification, consequences, recommended evaluation methods and specific conditions associated with were reviewed. Accordingly, two routes are defined with SCUE'team, Speech language pathologist, Geriatrics, Nursing and Nutrition. 1) opportune referral criteria of Speech language pathologist for clinical swallowing evaluation and 2) Early multidisciplinary screening and evaluation method of OD and aspiration risk.

The predictive dysphagia score (PreDyScore) in the short- and medium-term post-stroke: a putative tool in PEG indication.

PURPOSE: We performed an evaluation of dysphagia in an unselected series of strokes to identify factors causing persisting dysphagia at 1 month after onset and to formulate a predictive score. METHODS: We evaluated the association between dysphagia and clinical aspects (univariate analysis) at the 7th and 30th days after admission. We performed a multivariate logistic regression at the 30th day on the factors that were significant. We computed a simple score for predicting persistent dysphagia. RESULTS: We recruited 249 patients. At the 7th day, 94 patients were dysphagic (37.75%). Factors associated with dysphagia included TACI (OR 3.85), mRS ≥ 3 (OR 4.45), malnutrition (OR 2.69), and BMI ≥ 20 (OR 0.52). At the 30th day, 217 patients remained in the study, and dysphagia persisted in 75 (36.76%). The factors that were associated with dysphagia were age > 74 years (OR 1.99), TACI (OR 5.82), mRS score ≥ 3 (OR 4.31), malnutrition (OR 3.27), and BMI ≥ 20 (OR 0.45). The multivariate analysis indicated that mRS ≥ 3 (OR 1.80) and BMI ≥ 20 (OR 0.45) remained significantly associated with dysphagia. The best correlation with dysphagia was the sum of mRS and the reciprocal of the BMI multiplied by 100 ((mRS + 1 ∕ BMI) × 100). We named this score PreDyScore that ranged between 3.7 and 10.47. Using < 6 and > 8 as cutoffs, the sensitivity was 67.03%, and the specificity 95.65%. CONCLUSION: BMI < 20 and mRS ≥ 3 are easily measurable bedside predictive factors of persistent dysphagia. PreDyScore showed good sensitivity and very good specificity and enables the prediction of persistent dysphagia with great accuracy in any clinical setting.

Nível de comprometimento motor e deglutição em pacientes com paralisia cerebral / Level of gross motor function and swallowing in patients with cerebral palsy

INTRODUÇÃO: as condições motoras orais de pacientes com paralisia cerebral (PC), incluindo a função de deglutição, apresentam influência de diversos aspectos, dentre estes o comprometimento motor global. O Gross Motor Function Classification System (GMFCS) compreende o sistema mais utilizado na classificação das condições motoras globais desses pacientes. Um conhecimento mais amplo da influência das condições motoras globais na deglutição permitirá a identificação e intervenção precoces frente às alterações desta função. OBJETIVO: verificar as condições de deglutição de acordo com o nível de comprometimento motor global em pacientes com PC. MÉTODOS: setenta pacientes com PC, com média de idade de 4 anos e 8 meses e todos os níveis de classificação do GMFCS, atendidos por um centro de reabilitação brasileiro de referência foram avaliados quanto à deglutição. O diagnóstico de deglutição e sua gravidade foram comparados com o nível de comprometimento motor avaliado pelo GMFCS. RESULTADOS: houve diferença significante entre as condições de deglutição e os níveis motores do GMFCS, para as duas consistências oferecidas (pastoso e líquido). A distribuição dos graus de disfagia em relação ao nível motor mostrou piora desta de acordo com a piora na condição motora grossa. CONCLUSÃO: as condições de deglutição de pacientes com PC correlacionaram-se de forma significante com o nível de comprometimento motor estabelecido pelo sistema GMFCS, ou seja, quanto maior este nível de comprometimento, maior a gravidade da disfagia.

INTRODUCTION: the oral sensory-motor conditions of patients with cerebral palsy (CP), including the swallowing function, are influenced by several aspects, among them the global motor impairment. The Gross Motor Function Classification System (GMFCS) comprises the most used system for classifying the motor conditions of these patients. A understanding of the influence of global motor conditions on swallowing will allow for the early identification and intervention of this function. OBJECTIVE: to verify the swallowing conditions according to the level of global motor impairment in patients with CP. METHODS: seventy patients with CP, with mean age of 4 years and 8 months, all GMFCS classification levels, attended by a Brazilian referral rehabilitation center were evaluated for swallowing. The diagnosis of swallowing and its severity were compared with the level of motor impairment assessed by GMFCS. RESULTS: there was a significant difference between the swallowing conditions and the GMFCS motor levels, for the two consistencies offered (pasty and liquid). The distribution of the degrees of dysphagia in relation to the motor level showed worsening of this according to the worsening in the gross motor condition. CONCLUSION: the deglutition conditions of patients with CP correlated significantly with the level of motor impairment established by the GMFCS, that is, the higher level of impairment, the greater severity of dysphagia.

Sensory dysphagia: A case series and proposed classification of an under recognized swallowing disorder.

BACKGROUND: Although sensory feedback is a vital regulator of deglutition, it is not comprehensively considered in the standard dysphagia evaluation. Difficulty swallowing secondary to sensory loss may be termed "sensory dysphagia" and may account for cases receiving diagnoses of exclusion, like functional or idiopathic dysphagia. METHODS AND RESULTS: Three cases of idiopathic dysphagia were suspected to have sensory dysphagia. The patients had (1) effortful swallowing, (2) globus sensation, and (3) aspiration. Endoscopic sensory mapping revealed laryngopharyngeal sensory loss. Despite normal laryngeal motor function during voluntary maneuvers, laryngeal closure was incomplete during swallowing. The causes of sensory loss were identified: cranial neuropathy from Chiari malformation, immune-mediated neuronopathy, and nerve damage from prior traumatic intubation. CONCLUSIONS: Sensory loss may cause dysphagia without primary motor dysfunction. Sensory dysphagia should be classified as a distinct form of swallowing motility disorder to improve diagnosis. Increasing awareness and developing appropriate assessment tools may advance dysphagia care.

A Model-Based Approach to Predict Short-Term Toxicity Benefits With Proton Therapy for Oropharyngeal Cancer.

PURPOSE: The aim of this study was to generate normal tissue complication probability (NTCP) models in patients treated with either proton beam therapy (PBT) or intensity-modulated radiation therapy (IMRT) for oropharynx cancer and to use a model-based approach to investigate the added value of PBT in preventing treatment complications. METHODS AND MATERIALS: For patients with advanced-stage oropharynx cancer treated with curative intent (PBT, n = 30; IMRT, n = 175), NTCP models were developed using multivariable logistic regression analysis with backward selection. For PBT-treated patients, an equivalent IMRT plan was generated to serve as a reference to determine the benefit of PBT in terms of NTCP. The models were then applied to the PBT-treated patients to compare predicted and observed clinical outcomes (calibration-in-the-large). Five binary endpoints were analyzed at 6 months after treatment: dysphagia ≥ grade 2, dysphagia ≥ grade 3, xerostomia ≥ grade 2, salivary duct inflammation ≥ grade 2, and feeding tube dependence. Corresponding toxicity grading was based on National Cancer Institute Common Terminology Criteria for Adverse Events version 4. Paired t tests and Wilcoxon rank tests were used to compare mean NTCP results for endpoints between PBT and IMRT. RESULTS: NTCP models developed based on outcomes from all patients were applied to those receiving PBT. NTCP values were calculated for the equivalent IMRT plans for all PBT-treated patients, revealing significantly higher NTCP values with IMRT. PBT was associated with statistically significant reductions in the mean NTCP values for each endpoint at 6 months after treatment, with the largest absolute differences in rates of ≥grade 2 dysphagia and ≥grade 2 xerostomia. CONCLUSIONS: NTCP models predict significant improvements in the probability of short-term, treatment-related toxicity with PBT compared with IMRT for oropharyngeal cancer. This study demonstrates an NTCP model-based approach to compare predicted patient outcomes when randomized data are not available.

Ineffective Esophageal Motility Is Associated with Impaired Bolus Clearance but Does Not Correlate with Severity of Dysphagia.

BACKGROUND: Ineffective esophageal motility (IEM) is defined as a distal contractile integral < 450 mmHg/s/cm in at least 50% of ten liquid swallows on high-resolution esophageal manometry (HREM). Whether this latest definition correlates with degree of symptoms has not been studied. METHODS: Patients presenting for HREM prospectively rated their symptoms using the Eckardt score. Topography plots were retrospectively reviewed and classified according to the latest Chicago Classification. Patients with non-obstructive dysphagia and an Eckardt score of at least 1 were included. Patients with major motility disorders were excluded. Scores between patients with IEM (group A) and patients with normal classification (group B) were compared using two-tailed t-tests. Spearman's correlation coefficient was calculated to determine correlation between symptoms and percent bolus clearance. RESULTS: A total of 241 patients were screened; 33 patients met criteria for group A and 44 patients for group B. There was no difference between the two groups in mean symptom severity for dysphagia (1.63 vs. 1.61, P = 0.89), chest pain (0.67 vs. 0.75, P = 0.64), regurgitation (1.06 vs. 0.85, P = 0.32), or weight loss (0.85 vs. 0.49, P = 0.11). The percent bolus clearance was significantly lower in group A (46.5% vs. 76.7%, P > 0.01). There was a moderate inverse correlation between dysphagia and percent bolus clearance (R = - 0.37) in group A, but none in group B (R = 0.09). CONCLUSION: The classification of IEM did not discriminate from normal studies for symptom severity in our cohort. However, patients with IEM did have an inverse correlation between dysphagia score and bolus clearance, but those without IEM did not. Adding impedance information to the motor pattern classification should be considered in the symptom assessment in minor motility disorders.

Reliability, construct validity and usability of the Eating and Drinking Ability Classification System (EDACS) among Dutch children with Cerebral Palsy.

PURPOSE: To assess the interrater reliability, construct validity and usability of the Eating and Drinking Ability Classification System (EDACS) among Dutch children with Cerebral Palsy (CP) when used by speech and language therapists (SLTs) familiar and unfamiliar with the child's eating and drinking performance and parents. METHODS: Translation was undertaken using the method of Eremenco. Agreement between SLTs and parents when using EDACS was determined by intraclass correlation coefficient (ICC) and linear weighted Kappa (κW). Associations with other functional classification systems including the Dysphagia Management Staging Scale (DMSS) were investigated to determine construct validity by Kendall's tau-b. RESULTS: Thirty-one SLTs classified 149 children (67 girls; mean 10 y, SD 4 y, range 3-21 y) with EDACS. Pairs of SLTs showed good agreement ([ICC] = 0.84; 95% confidence interval [CI] 0.79-0.88; [κW] = 0.71). Eighty-one parents showed good agreement with SLTs (n= 31) as well (ICC = 0.80; 95% CI 0.71-0.87; κW= 0.61). There was a significant and strong positive correlation of EDACS with DMSS (Kendall's tau-b 0.81) supporting its construct validity. Usability of EDACS was generally good. CONCLUSION: The Dutch version of EDACS is reliable and valid, and can be used easily by (familiar and unfamiliar) SLTs and parents of children with CP. Parents and professionals showed a high level of consistency when classifying eating and drinking abilities. EDACS enables uniform and efficient communication about safety and efficiency of functional eating and drinking ability in clinical and research contexts.

Evaluation and classification of post-extubation dysphagia in critically ill patients. / Avaliação e classificação da disfagia pós-extubação em pacientes críticos.

OBJECTIVE: to identify factors associated with dysphagia in patients undergoing prolonged orotracheal intubation (pOTI) and the post-extubation consequences. METHODS: 150 patients undergoing pOTI participated in the study, evaluated according to the deglutition functional level (American Speech Language - Hearing Association National Outcome Measurement System - ASHA NOMS), severity determination (The Simplified Acute Physiology Score - SOFA) and submitted to collection of variables age, mortality, days of orotracheal intubation, number of sessions to introduce oral diet, and days to hospital discharge. We grouped patients according to ASHA classification: 1 (levels 1 and 2), 2 (levels 3, 4 and 5) and 3 (levels 6 and 7). RESULTS: the variables associated with impaired deglutition functionality were age (p<0.001), mortality (p<0.003), OTI days (p=0.001), number of sessions to introduce oral diet (p<0.001) and days to hospital discharge (p=0.018). Multiple comparisons indicated significant difference between ASHA1 and ASHA2 groups in relation to ASHA3 group. ASHA1 and ASHA2 groups had a lower SOFA score when compared with the ASHA3 group (p=0.004). Only 20% of ASHA1 patients and 32% of ASHA2 patients presented safe deglutition levels before discharge. CONCLUSION: factors associated with dysphagia in patients submitted to pOTI were age over 55 years and orotracheal intubation time (greater in the cases with worse deglutition functionality). The post-extubation consequences were increased mortality and length of hospital stay in the presence of dysphagia.

OBJETIVO: identificar os fatores associados à disfagia em pacientes submetidos à intubação orotraqueal prolongada (IOTp) e as consequências pós-extubação. MÉTODOS: participaram do estudo 150 pacientes submetidos à IOTp, avaliados segundo o nível funcional da deglutição (American Speech Language - Hearing Association National Outcome Measurement System - ASHA NOMS), a determinação da gravidade (The Simplified Acute Physiology Score - SOFA) e a coleta das seguintes variáveis: idade, mortalidade, dias de intubação orotraqueal, número de atendimentos para introdução da alimentação oral e dias para alta hospitalar. Os pacientes foram agrupados de acordo com a classificação do ASHA: 1 (níveis 1 e 2), 2 (níveis 3, 4 e 5) e 3 (níveis 6 e 7). RESULTADOS: as análises indicaram as seguintes variáveis associadas a pior funcionalidade da deglutição: idade (p<0,001), mortalidade (p<0,003); dias de IOT (p=0,001), número de atendimentos para introdução de dieta oral (p<0,001) e dias para alta hospitalar (p=0,018). As comparações múltiplas indicaram diferença significante na comparação dos grupos ASHA1 e ASHA2 em relação ao grupo ASHA3. Os grupos ASHA1 e ASHA2 apresentaram menor score na SOFA quando comparados ao grupo ASHA3 (p=0,004). Somente 20% dos pacientes do grupo ASHA1 e 32% dos pacientes do ASHA2 apresentaram níveis seguros de deglutição antes da alta hospitalar. CONCLUSÃO: os fatores associados à disfagia em pacientes submetidos à IOTp foram: idade acima de 55 anos e tempo de intubação orotraqueal (maior nos casos com pior funcionalidade da deglutição). As consequências pós-extubação foram: aumento da mortalidade e do tempo de internação hospitalar na presença da disfagia.

Identification of Phenotypic Patterns of Dysphagia: A Proof of Concept Study.

Purpose: The purpose of the current project was to explore the feasibility for subtyping dysphagia traits or patterns of scores in a subset of data from the Modified Barium Swallow Impairment Profile global registry in patients referred to videofluoroscopic swallowing studies across 5 common medical categories: (a) cardiothoracic, (b) gastroenterology, (c) head and neck cancer, (d) neurology, and (e) pulmonary. Method: Videofluoroscopic swallowing study imaging and Modified Barium Swallow Impairment Profile metrics were used to evaluate 235 patients with dysphagia grouped into 1 of the 5 categories. Two summative domain scores (oral total [OT] and pharyngeal total [PT]) and 17 component scores were tested for differences among the categories. Results: When compared with the gastroenterology category, significantly higher OT/PT scores were observed in neurology and pulmonary categories (all p values < .05). Four oral and 6 pharyngeal domain components significantly differed across medical categories: tongue control during bolus hold (all p values < .04). Conclusions: The results of this feasibility study demonstrate that summative scores of swallowing physiology alone are not sufficiently robust to distinguish subtypes of dysphagia in broad, heterogeneous medical categories. Using OT/PT as subtypes only separated gastroenterology from the other categories, suggesting overlap in OT/PT scores between the latter categories.

Findings of postoperative clinical assessment of swallowing in infants with congenital heart defect. / Achados da avaliação clínica da deglutição em lactentes cardiopatas pós-cirúrgicos.

PURPOSE: Describe the findings of postoperative clinical evaluation of swallowing in infants with congenital heart disease (CHD) in a reference hospital in southern Brazil. METHODS: This is a cross-sectional study conducted postoperatively with infants with medical diagnosis of CHD aged 0-6 months in a Pediatric Intensive Care Unit. Exclusion criteria comprised infants with neurological and respiratory impairments, craniofacial malformation, structural alteration in the upper airways, and suspicion or diagnosis of genetic syndromes. Clinical evaluation was performed through partial application of the Assessment of Pediatric Dysphagia protocol. Regarding statistical analysis, the quantitative variables were described by median and interquartile range and the qualitative variables were described by absolute and relative frequencies. Non-parametric tests were used to evaluate the associations. RESULTS: Of the 31 infants in the sample, 23 (74.2%) were classified with some degree of dysphagia. Significant difference was observed in the clinical evaluation performed with bottle-feeding compared with breast-feeding; a larger number of swallowing disorders was also found in bottle-feeding. Statistically significant correlation was observed between duration of orotracheal intubation (OTI) >24 h and presence of dysphagia. CONCLUSION: Postoperative clinical evaluation enabled description of swallowing impairments in infants with CHD regardless of the type of feeding offered, as well as identification of presence of dysphagia in a large number of individuals in the sample and its association with duration of OTI >24 h.

OBJETIVO: Descrever os achados da avaliação clínica da deglutição em lactentes cardiopatas pós-cirúrgicos de um hospital de referência do sul do Brasil. MÉTODO: Trata-se de um estudo transversal, realizado em uma Unidade de Terapia Intensiva Pediátrica, no qual participaram lactentes com diagnóstico médico de cardiopatia congênita e idade entre 0 e 6 meses, após procedimento cirúrgico. Foram excluídos da amostra aqueles que apresentaram: comprometimento neurológico, malformação craniofacial, alterações estruturais de vias aéreas superiores, comprometimento respiratório, suspeita ou diagnóstico de síndrome genética. A avaliação clínica foi realizada por meio de aplicação parcial do Protocolo de Avaliação da Disfagia Pediátrica. Em relação às análises estatísticas, as variáveis quantitativas foram descritas por mediana e amplitude interquartílica e as variáveis qualitativas foram descritas por frequências absolutas e relativas. Testes não paramétricos foram aplicados para avaliar as associações. RESULTADOS: Dos 31 lactentes que compuseram a amostra, 23 (74,2%) foram classificados com algum grau de disfagia. Houve diferença significativa na avaliação clínica realizada com a oferta de mamadeira quando comparada à oferta em seio materno, em mamadeira também foi observado maior número de alterações da deglutição. A relação entre o tempo de intubação orotraqueal maior que 24 horas e a presença de disfagia apresentaram associação estatisticamente significativa. CONCLUSÃO: Por meio da ACD foi possível descrever as alterações de deglutição em lactentes cardiopatas após procedimento cirúrgico, independentemente do modo de oferta. Além de identificar a presença de disfagia em número elevado da amostra e sua associação com o período de IOT maior de 24 horas.

Grading Dysphagia as a Toxicity of Head and Neck Cancer: Differences in Severity Classification Based on MBS DIGEST and Clinical CTCAE Grades.

Clinician-reported toxicity grading through common terminology criteria for adverse events (CTCAE) stages dysphagia based on symptoms, diet, and tube dependence. The new dynamic imaging grade of swallowing toxicity (DIGEST) tool offers a similarly scaled five-point ordinal summary grade of pharyngeal swallowing as determined through results of a modified barium swallow (MBS) study. This study aims to inform clinicians on the similarities and differences between dysphagia severity according to clinical CTCAE and MBS-derived DIGEST grading. A cross-sectional sample of 95 MBS studies was randomly selected from a prospectively-acquired MBS database among patients treated with organ preservation strategies for head and neck cancer. MBS DIGEST and clinical CTCAE dysphagia grades were compared. DIGEST and CTCAE dysphagia grades had "fair" agreement per weighted κ of 0.358 (95% CI .231-.485). Using a threshold of DIGEST ≥ 3 as reference, CTCAE had an overall sensitivity of 0.50, specificity of 0.84, and area under the curve (AUC) of 0.67 to identify severe MBS-detected dysphagia. At less than 6 months, sensitivity was 0.72, specificity was 0.76, and AUC was 0.75 while at greater than 6 months, sensitivity was 0.22, specificity was 0.90, and AUC was 0.56 for CTCAE to detect dysphagia as determined by DIGEST. Classification of pharyngeal dysphagia on MBS using DIGEST augments our understanding of dysphagia severity according to the clinically-derived CTCAE while maintaining the simplicity of an ordinal scale. DIGEST likely complements CTCAE toxicity grading through improved specificity for physiologic dysphagia in the acute phase and improved sensitivity for dysphagia in the late-phase.

Avaliação e classificação da disfagia pós-extubação em pacientes críticos / Evaluation and classification of post-extubation dysphagia in critically ill patients

RESUMO Objetivo: identificar os fatores associados à disfagia em pacientes submetidos à intubação orotraqueal prolongada (IOTp) e as consequências pós-extubação. Métodos: participaram do estudo 150 pacientes submetidos à IOTp, avaliados segundo o nível funcional da deglutição (American Speech Language - Hearing Association National Outcome Measurement System - ASHA NOMS), a determinação da gravidade (The Simplified Acute Physiology Score - SOFA) e a coleta das seguintes variáveis: idade, mortalidade, dias de intubação orotraqueal, número de atendimentos para introdução da alimentação oral e dias para alta hospitalar. Os pacientes foram agrupados de acordo com a classificação do ASHA: 1 (níveis 1 e 2), 2 (níveis 3, 4 e 5) e 3 (níveis 6 e 7). Resultados: as análises indicaram as seguintes variáveis associadas a pior funcionalidade da deglutição: idade (p<0,001), mortalidade (p<0,003); dias de IOT (p=0,001), número de atendimentos para introdução de dieta oral (p<0,001) e dias para alta hospitalar (p=0,018). As comparações múltiplas indicaram diferença significante na comparação dos grupos ASHA1 e ASHA2 em relação ao grupo ASHA3. Os grupos ASHA1 e ASHA2 apresentaram menor score na SOFA quando comparados ao grupo ASHA3 (p=0,004). Somente 20% dos pacientes do grupo ASHA1 e 32% dos pacientes do ASHA2 apresentaram níveis seguros de deglutição antes da alta hospitalar. Conclusão: os fatores associados à disfagia em pacientes submetidos à IOTp foram: idade acima de 55 anos e tempo de intubação orotraqueal (maior nos casos com pior funcionalidade da deglutição). As consequências pós-extubação foram: aumento da mortalidade e do tempo de internação hospitalar na presença da disfagia.

ABSTRACT Objective: to identify factors associated with dysphagia in patients undergoing prolonged orotracheal intubation (pOTI) and the post-extubation consequences. Methods: 150 patients undergoing pOTI participated in the study, evaluated according to the deglutition functional level (American Speech Language - Hearing Association National Outcome Measurement System - ASHA NOMS), severity determination (The Simplified Acute Physiology Score - SOFA) and submitted to collection of variables age, mortality, days of orotracheal intubation, number of sessions to introduce oral diet, and days to hospital discharge. We grouped patients according to ASHA classification: 1 (levels 1 and 2), 2 (levels 3, 4 and 5) and 3 (levels 6 and 7). Results: the variables associated with impaired deglutition functionality were age (p<0.001), mortality (p<0.003), OTI days (p=0.001), number of sessions to introduce oral diet (p<0.001) and days to hospital discharge (p=0.018). Multiple comparisons indicated significant difference between ASHA1 and ASHA2 groups in relation to ASHA3 group. ASHA1 and ASHA2 groups had a lower SOFA score when compared with the ASHA3 group (p=0.004). Only 20% of ASHA1 patients and 32% of ASHA2 patients presented safe deglutition levels before discharge. Conclusion: factors associated with dysphagia in patients submitted to pOTI were age over 55 years and orotracheal intubation time (greater in the cases with worse deglutition functionality). The post-extubation consequences were increased mortality and length of hospital stay in the presence of dysphagia.
