Assessment of pediatric dysphagia and feeding disorders: Clinical and instrumental approaches

Assessing Dysphagia in the Child

Swallowing problems in children can occur for a variety of reasons, and assessment varies based on the age of the child, underlying medical problems, and results of the clinical swallow evaluation. The need for interdisciplinary management with speech language pathologists skilled in the management of children with dysphagia is imperative to identify the components of swallowing that are impaired and provide specific recommendations for safe and adequate nutrition supporting growth, development, and oral feeding if possible. This study focuses on the types of assessment tools available and how and when they are utilized for children of different ages and abilities.

Neurologic Dysphagia

Dysphagia is commonly associated with neurologic/neuromuscular disorders including prematurity, cerebral palsy, traumatic brain injury, brain tumors, genetic disorders, and neuromuscular diseases. This article aims to review the major categories of neurologic dysphagia, to outline specific findings and special considerations for each population, and to acknowledge the importance of integrating each patient's medical prognosis, goals of care, and developmental stage into a multidisciplinary treatment plan.

Working Toward Recommended Terminology in the Canadian Preschool Speech-Language Pathology Context

PURPOSE

This quality improvement project aimed to address the inconsistent use of clinical labels across a preschool speech and language program in Ontario, Canada. The study investigated whether a multicomponent knowledge translation (KT) intervention could increase speech-language pathologists' (SLPs') knowledge about the recommended clinical labels, motivate their intentions to use the labels, and facilitate practice change during a 3-month pilot period.

METHOD

The diffusion of innovations theory was utilized to identify and address known and suspected barriers and facilitators that could influence the adoption of consistent terminology. The intervention was evaluated using a pre-experimental study design (with pre, post, and follow-up testing) and included two phases: Phase 1 involved the pretraining survey, KT intervention, and posttraining survey, and Phase 2 included an exit survey after a 3-month pilot period.

RESULTS

Five hundred twenty-nine SLPs in Phase 1 and 387 SLPs in Phase 2 participated. Following the web-based intervention, SLPs demonstrated improved knowledge about the recommended labels with most indicating intentions to communicate the labels going forward. SLPs also reported increased comfort using labels and positive views on their importance and value. After the 3-month pilot period, SLPs' reported use of most recommended labels decreased, as did ratings of comfort, value, and importance. However, most SLPs reported intentions to use the labels going forward.

CONCLUSIONS

Despite having intentions to adopt the recommended labels, the lack of implementation by SLPs suggests the presence of additional barriers impacting their use of the recommended clinical labels in practice. Future work should investigate clinician-identified barriers to inform future implementation efforts.

Prolonged use of a soft diet during early growth and development alters feeding behavior and chewing kinematics in a young animal model

In infants and children with feeding and swallowing issues, modifying solid foods to form a liquid or puree is used to ensure adequate growth and nutrition. However, the behavioral and neurophysiological effects of prolonged use of this intervention during critical periods of postnatal oral skill development have not been systematically examined, although substantial anecdotal evidence suggests that it negatively impacts downstream feeding motor and coordination skills, possibly due to immature sensorimotor development. Using an established animal model for infant and juvenile feeding physiology, we leverage X-ray reconstruction of moving morphology to compare feeding behavior and kinematics between 12-week-old pigs reared on solid chow (control) and an age- and sex-matched cohort raised on the same chow softened to a liquid. When feeding on two novel foods, almond and apple, maintenance on a soft diet decreases gape cycle duration, resulting in a higher chewing frequency. When feeding on almonds, pigs in this group spent less time ingesting foods compared to controls, and chewing cycles were characterized by less jaw rotation about a dorsoventral axis (yaw) necessary for food reduction. There was also a reduced tendency to alternate chewing side with every chew during almond chewing, a behavioral pattern typical of pigs. These more pronounced impacts on behavior and kinematics during feeding on almonds, a tougher and stiffer food than apples, suggest that food properties mediate the behavioral and physiological impacts of early texture modification and that the ability to adapt to different food properties may be underdeveloped. In contrast, the limited effects of food texture modification on apple chewing indicate that such intervention/treatment does not alter feeding behavior of less challenging foods. Observed differences cannot be attributed to morphology because texture modification over the treatment period had limited impact on craniodental growth. Short-term impacts of soft-texture modification during postweaning development on feeding dynamics should be considered as potential negative outcomes of this treatment strategy.

Role of fiberoptic endoscopic evaluation of swallowing (FEES) in children with suspected dysphagia

OBJECTIVE

To assess FEES findings in defining oral feeding safety in children with suspected dysphagia, comparing them with clinical feeding evaluation results.

METHODS

This study comprised a case series involving children with suspected dysphagia, referred for evaluation by otolaryngologists and speech-language pathologists (SLPs) at a Brazilian quaternary public university hospital. These children underwent both clinical evaluations and fiberoptic endoscopic evaluation of swallowing (FEES), with a comprehensive collection of demographic and clinical data. Subsequently, the authors performed a comparative analysis of findings from both assessments.

RESULTS

Most patients successfully completed the FEES procedure (93.7%), resulting in a final number of 60 cases included in the study. The prevalence of dysphagia was confirmed in a significant 88% of these cases. Suspected aspiration on clinical SLP evaluation was present in 34 patients. Of these, FEES confirmed aspiration or penetration in 28 patients. Among the 35 patients with aspiration or penetration on FEES, 7 (20%) had no suspicion on SLP clinical assessment. All seven patients in whom clinical SLP evaluation failed to predict penetration/aspiration had neurological disorders. The median age of the children was 2.8 years, and 49 (81.6%) had neurological disorders, while 35 (58.3%) had chronic pulmonary disease. The most prevalent complaints were choking (41.6%) and sialorrhea (23.3%).

CONCLUSION

FEES can diagnose structural anomalies of the upper aerodigestive tract and significantly contribute to the detection of aspiration and penetration in this group of patients with suspected dysphagia, identifying moderate and severe dysphagia even in cases where clinical assessment had no suspicion.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Clinical Feeding and Swallowing Evaluation for the School-Based Speech-Language Pathologist

PURPOSE

From preschool through high school, eating is part of the school day. Children with feeding and/or swallowing issues are now in our neighborhood schools, our responsibility in our care, and require adequate nutrition and hydration to participate in school and access the curriculum. The whole child is in school, including all of their medical, behavioral, social, and educational needs. This clinical focus article describes a holistic process of evaluating swallowing and feeding in the school setting for the school speech-language pathologist (SLP) leading the team supporting the child.

METHOD

This clinical focus article explores the evaluation process in the educational setting for the school SLP in identification of pediatric feeding disorders (PFDs), which can involve dysphagia. Detailed descriptions of the related U.S. educational law, PFD, assessment processes for the multiple systems relating to eating, and collaboration with an interdisciplinary team are highlighted. Using the four overlapping domains of PFD (medical, psychosocial, feeding skill-based systems and associated nutritional aspects), medical and background history gathering; integration with instrumental results; and the need to consider the complex interaction of developmental, physical, cognitive, social, behavioral, family, and cultural aspects in the evaluation are detailed.

CONCLUSIONS

School-age children require safe and adequate nutrition and hydration for learning and social participation. The SLP has a lead role in the school team in evaluating swallowing and feeding, and developing a plan for team implementation. A holistic school-based SLP clinical evaluation process is described.

Is Chewing Performance Related to Dietary Intake in Children with Cerebral Palsy?

To examine the relationship between chewing performance and dietary intakes in children with Cerebral Palsy (CP). Forty children with CP aged between 2 and 6 years were included. The Karaduman Chewing Performance Scale (KCPS) and the Mastication Observation and Evaluation (T-MOE) instruments were used to evaluate chewing performance. Daily dietary intakes were measured from a 24-h food record with digital photographs including the amount and textures of all foods consumed during the meal. Chewing function was impaired in 70% of children. There was a negative low-to-moderate correlation between KCPS scores and daily protein intake (r = -0.32, p = 0.04), but not with energy and other macronutrients. The percentage of daily dietary intakes from 'liquid-blenderized' foods were positively correlated with KCPS, and negatively correlated with T-MOE scores (p < 0.001). There was a significant negative association between the percentage of daily dietary intakes from 'easy to chew & regular solid' foods and KCPS scores, and a significant positive association was found with T-MOE scores. In conclusion, the amount of daily protein intake decreased, and daily intake ratios of energy and macronutrients from liquid-blenderized foods increased as chewing performance decreased in children with CP. Timely diagnosis and treatment of chewing dysfunction can serve as a useful treatment option to ensure adequate dietary intake in children with CP, and also to decrease the burden of their parents and improve their quality of life.

Validation and cultural adaptation of a Greek Version of Pediatric Eating Assessment Tool 10 (PEDI - EAT - 10) in Greek-Cypriot Parents

PURPOSE

The Pediatric Eating Assessment Tool (PEDI-EAT-10) is a parents/caregivers screening tool that assesses pediatric patients at risk of penetration and/or aspiration symptoms. The aim of this study was the validation of PEDI-EAT-10 in the Greek language.

MATERIALS AND METHODS

This cross-sectional study included 222 parents/caregivers of children with (n = 122) and without (n = 100) feeding and/or swallowing disorders, with age range 3 - 12 years. The children were selected from Cypriot schools and health settings. All parents filled out the PEDI-EAΤ-10 questionnaire and after its initial completion, it was re-administered after 2 weeks.

RESULTS

A statistically significant difference was observed in the PEDI-EAT-10 total mean scores between the study's two groups [t (220) = 9.886, p < 0.001]. Internal consistency was high (Cronbach's alpha= 0.801) with very good split-half reliability equal to 0.789. A significant and strong test-retest reliability was computed (r = 0.998, p < 0.001). The PEDI-EAT-10 cutoff point was 11.00 (AUC: 0.869, p < 0.001) for children with feeding and/or swallowing disorders in accordance with the PAS scale.

CONCLUSIONS

In conclusion, the Greek version of PEDI-EAT-10 is shown to be a valid and reliable screening tool for the assessment of the pediatric population with a risk of dysphagia.

Risk of Aspiration Increased by Post-swallow Residue in Infant Fiberoptic Endoscopic Evaluation of Swallowing (FEES)

OBJECTIVE

To assess the risk of aspiration associated with post-swallow residue subsites in Fiberoptic Endoscopic Evaluation of Swallowing (FEES) in bottle-fed infants <1 year of age.

METHODS

This is a retrospective matched-pairs cohort study at an academic tertiary children's hospital. FEES and Videofluoroscopic Swallowing Study (VFSS) trials performed within the same infant <5 days apart were paired by matching bolus consistency and bottle flow rate. Positive aspiration was defined by the "or rule" in which aspiration is positive when either FEES or VFSS within a matched pair is positive.

RESULTS

Eighty-seven FEES-VFSS matched pairs from 29 patients (16 males; mean [SD] age, 2.9 [2.8] months) were included. The rate of positive aspiration, as defined by the "or rule", was 59% (51/87). In FEES, post-swallow pyriform sinus residue was present in 16% (14/87) and anterior commissure residue 27% (31/87). Risk of positive aspiration was increased by pyriform sinus residue (odds ratio [OR] 5.4, 95% confidence interval [CI] 1.9-19.3, p < 0.01) and anterior commissure residue in FEES (OR 2.5, 95% CI 1.1-6.1, p = 0.03). In the neonate subgroup, <1 month of age, multivariate-adjusted analysis showed that anterior commissure residue had better diagnostic accuracy for aspiration than in older infants (overall 70% vs. 42%, p < 0.01; sensitivity 60% vs. 10%, p < 0.01), whereas pyriform sinus residue had worse accuracy (overall 41% vs. 70%, p = 0.02; sensitivity 13% vs. 43%, p = 0.02).

CONCLUSION

This study demonstrates that pyriform sinus and anterior commissure residue during infant FEES were associated with fivefold and twofold increased risk of aspiration, respectively.

LEVEL OF EVIDENCE: 3

Using a retrospective matched-pairs cohort, this study assesses the diagnostic accuracy of post-swallow residue in FEES for predicting aspiration. Laryngoscope, 134:1431-1436, 2024.

Best practice recommendations for speech-language pathology in children with neuromuscular disorders: A Delphi-based consensus study

PURPOSE

Speech-language pathology (SLP) is considered an essential intervention due to the high prevalence of dysphagia and dysarthria in paediatric neuromuscular disorders (pNMD). Evidence-based guidelines for SLP in pNMD are missing and children could be deprived the best of care. This study aimed to achieve consensus and present best practice recommendations on SLP intervention in pNMD.

METHOD

A modified Delphi technique was used with a panel of experienced Dutch speech-language pathologists. In two online survey rounds and a face-to-face consensus meeting, the SLP experts proposed intervention items for cases of four types of pNMD (congenital myopathy, Duchenne muscular dystrophy, myotonic dystrophy type 1, and spinal muscular atrophy type 2), covering symptoms of dysphagia, dysarthria, drooling, and oral hygiene problems. They rated the level of agreement.

RESULT

Intervention items that achieved consensus were incorporated into best practice recommendations. These recommendations cover six core intervention components (wait and see, explanation and advice, training and treatment, aids and adjustments, referral to other disciplines, and monitoring) suitable for the described symptoms.

CONCLUSION

Insight into treatment options is essential to facilitate speech-language pathologists in clinical decision-making. The current study led to best practice recommendations for speech-language pathologists working within the field of pNMD.

Influence of frame rate in detecting oropharyngeal aspiration in paediatric videofluoroscopic swallow studies - An observational study

OBJECTIVES

The videofluoroscopic swallow study (VFSS), currently the gold standard for assessing aspiration in children, incurs radiation. Adhering to the ALARA principle is crucial in minimising radiation dose whilst obtaining accurate diagnostic information in children. International adult VFSS guidelines recommend a capture rate of 30 frames per second (fps). Higher capture rates increase radiation yet there is limited evidence on best practice VFSS capture rates in children, particularly on thin fluid consistency-the fastest viscosity with the highest potential for missed aspiration on slower capture rates. We aimed to determine if image acquisition at 30fps versus 15fps alters the accuracy of detecting aspiration when assessing thin fluids during paediatric VFSS.

MATERIALS & METHODS

Seventeen speech language pathologists (SLPs) blindly rated a total of 2,356 swallow loops for the presence/absence of aspiration from VFSS recordings of 13 infants/children drinking thin fluids. 76 swallow loops were randomly presented at 15 versus 30fps, on two occasions. Area under receiver operating curve (aROCs) was used to compare the accuracy of aspiration ratings at 15 versus 30fps compared to a comparison set. The intraclass correlation coefficient (ICC) was used to examine rater reliability.

RESULTS

Accuracy for detecting aspiration was near-identical at 15fps (aROC:0.97; 95%CI:0.96-0.97) and 30fps (0.96; 95%CI 0.96-0.97). Good inter-rater (ICC:0.82; 95%CI:0.72-0.89) and intra-rater reliability among the raters (ICC:0.89; 95%CI:0.82-0.93) was found.

CONCLUSION

Using 15fps in paediatric VFSS when assessing thin fluid consistency aspiration provides a similar detection rate to using 30fps. As 15fps would have a lower radiation dose than 30fps, we recommend using 15fps when undertaking VFSS in children.

CLINICAL RELEVANCE STATEMENT

Adhering to the ALARA principles, a capture rate of 15fps should be used in paediatric VFSS for assessment on thin fluids.

Evolution of swallowing and feeding abilities of neonates with hypoxic-ischaemic encephalopathy during hospitalisation: A case series

PURPOSE

To describe the evolution of swallowing and feeding abilities of neonates with hypoxic-ischaemic encephalopathy (HIE) during hospitalisation.

METHOD

A longitudinal cohort study was used. Twenty-nine participants (median age 39.0 weeks [IQR = 2.0 weeks]) with mild (n = 7), moderate (n = 19) and severe (n = 3) HIE were included. Clinical swallowing and feeding assessments were conducted at introduction of oral feeds and at discharge using the Neonatal Feeding Assessment Scale (NFAS). Videofluoroscopic swallow studies (VFSS) supplemented the NFAS before discharge.

RESULT

Approximately two thirds of participants showed symptoms of oropharyngeal dysphagia (OPD) during initial NFAS and VFSS. Significantly fewer OPD symptoms occurred at discharge NFAS (p = 0.004). Endurance during non-nutritive sucking (p < 0.001) and nutritive sucking (p < 0.001) significantly improved. Nine participants (31.0%) demonstrated penetration or aspiration. Most aspiration events were silent (60%). Instrumental assessment identified pharyngeal phase dysphagia more effectively than bedside evaluation. High proportions of participants displayed OPD symptoms regardless of HIE severity. The correlation between OPD severity and the length of hospitalisation (p = 0.052) was not significant.

CONCLUSION

All grades of HIE should be considered for early intervention by speech-language pathologists before discharge. Findings may be valuable to neonatal feeding teams.

Establishing Normative Values for Healthy Term Infant Feeding Performance: Neonatal Eating Assessment Tool-Mixed, Oral Feeding Scale, and Early Feeding Skills Assessment

PURPOSE

Infants with perceived feeding problems are frequently referred for assessment of their feeding abilities. However, little is known regarding how healthy nondysphagic infants perform on commonly used assessments, making determination of impairment difficult. The aim of this investigation was to elucidate the characteristics of healthy term infant feeding performance using three commonly employed clinical assessments: Neonatal Eating Assessment Tool-Mixed (NeoEat-Mixed), Oral Feeding Scale, and Early Feeding Skills (EFS).

METHOD

In this prospective case-control study, we recruited 30 infants without feeding impairments to undergo video-monitored bottle feeds under their normal feeding conditions. Caregiver perception of infant feeding was evaluated using the NeoEat-Mixed. Milk ingestion was monitored real time using the Oral Feeding Scale for rate of milk transfer and modified proficiency as characterized by the total volume consumed out of the total volume the caregiver provided. Videos were analyzed by two speech pathologists using the EFS assessment. Descriptive statistics were used to characterize performance.

RESULTS

Participants underwent feeding monitoring at an average chronological age of 4 ± 2 months. Caregivers primarily reported normal, nonconcerning feeding patterns across all of the NeoEAT-Mixed outcomes. Infants consumed milk at an average rate of transfer of 7 ± 3 ml/min, a modified proficiency of 50 ± 21%, and achieved the highest OFS score of 4 (93%, n = 28). The majority of infants scored the best EFS score (mature-3) as it related to the absence of color changes during the feed (97%, n = 29), although commonly scored in the worst EFS score (immature-1) in their presentation of one or more compelling stress cues (63%, n = 19).

CONCLUSION

Establishing healthy term infant normative values for commonly used feeding assessments is critical in accurately distinguishing infants with feeding impairments from those with normal developmental variants.

Fiberoptic Endoscopic Evaluation of Swallowing in the Breastfeeding Infant

OBJECTIVE

To demonstrate the importance of utilizing fiberoptic endoscopic evaluation of swallowing (FEES) when evaluating breastfeeding infants with suspected dysphagia. Failure to recognize and account for the fundamentally different physiology of the primarily breastfed infant can lead to false assumptions about the safety of breastfeeding in this understudied patient population.

METHODS

Case-series. The medical records of patients referred to an urban, university-based, pediatric hospital for FEES from February 2017 to October 2020 were reviewed. Their presenting symptoms, dysphagia severity, comorbidity, dysphagia workup, and management were analyzed. The standardized Dysphagia Outcome and Severity Scale was used to appraise dysphagia severity.

RESULTS

204 FEES exams were reviewed. 35 were conducted on breastfed infants. 34 of the 35 infants calmed for the FEES exam while breastfeeding. Cohorts were defined by a particular presenting sign (cough, laryngeal congestion, choking, and respiratory illness) and anatomical characteristic (laryngomalacia, vocal cord paralysis, aspiration, penetration, etc.) and then compared to all other exams. The average dysphagia score for all the exams was 2.37. Patients presenting with laryngeal congestion had an average dysphagia score of 2.81. There was no difference in dysphagia score based on comorbidities or anatomy.

CONCLUSIONS

FEES is the instrumental exam of choice when evaluating a primarily breastfed infant who has suspected dysphagia. The exam is well tolerated and provides accurate, objective information while accounting for this population's unique swallowing physiology. Primarily breastfed infants presenting with laryngeal congestion are more likely to have clinically worse dysphagia than those presenting with other clinical symptoms.

A time and cost analysis of speech pathology paediatric feeding services delivered in-person versus via telepractice

INTRODUCTION

Telepractice models of care have the potential to reduce the time and financial burdens that consumers may experience accessing healthcare services. The current study aimed to conduct a time and financial cost analysis of paediatric feeding appointments accessed via telepractice (using videoconferencing) compared to an in-person model.

METHODS

Parents of 44 children with paediatric feeding disorders (PFDs) residing in a metropolitan area completed three questionnaires relating to (a) demographics, (b) time and cost for in-person care and (c) time and cost for telepractice. Both cost questionnaires collected data required for direct and indirect costs comparisons (e.g. out-of-pocket costs associated with the appointment (direct), time away from usual duties (indirect)). Average number of services accessed by each participant, and PFD appointments conducted annually by the service, were collected from service statistics. Analysis involved cost minimisation and cost modelling from a societal perspective.

RESULTS

The telepractice appointment resulted in significant time (p = 0.007) and cost (AUD$95.09 per appointment, SD = AUD$64.47, p = < 0.0001) savings per family. The health service cost was equivalent for both models (AUD$58.25). Cost modelling identified cost savings of up to AUD$475.45 per family if 50% of appointments in a 10-session block were converted to telepractice. Potential cost savings of AUD$68,750.07 per annum to society could be realised if 50% of feeding appointments within the service were provided via telepractice.

DISCUSSION

The telepractice model offered both time and cost benefits. Future service re-design incorporating hybrid services (in-person and telepractice) will help optimise benefits and minimise burden for families accessing services for PFDs.

Evolution of Feeding and Developmental Outcomes in Infants With Moderate Hypoxic-Ischemic Encephalopathy: A Pilot Study

The purpose of the study was to describe the evolution of outcomes among full-term infants with moderate hypoxic-ischemic encephalopathy (HIE); from their early swallowing and feeding abilities during hospitalization, to their later developmental outcomes at 6 and 12 months. Four participants with moderate HIE were recruited. Early feeding and swallowing were assessed using the Neonatal Feeding Assessment Scale and video fluoroscopic swallow studies. Developmental assessments were conducted at 6 and 12 months using the Rossetti Infant-Toddler Language Scale and Vineland-3 Scale. All participants displayed atypical outcomes throughout the study, including oropharyngeal dysphagia initially during hospitalization. All participants were discharged on oral feeds but some breastfeeding difficulties persisted. Variable but pervasive developmental delays were found among all participants at 6 and 12 months. This study emphasizes the need for consistent early intervention from the neonatal period onward, for all infants with moderate HIE. Future studies should use larger cohorts, longer follow-up, and correlational designs.

Investigation of Assessment Tools in the Area of Pediatric Feeding Evaluation: A Mixed-Methods Study

IMPORTANCE

The new diagnostic code for pediatric feeding disorder (PFD) in the International Classification of Diseases, 10th edition, Clinical Modification, requires that occupational therapists and speech-language pathologists (SLPs) use valid and reliable assessment tools that capture the complexity of PFD.

OBJECTIVE

To determine current assessment tools that clinicians are using across the four domains of PFD: (1) medical factors, (2) nutrition factors, (3) feeding skill factors, and (4) psychosocial factors. A secondary objective was to obtain clinicians' perceptions of the assessment tools.

DESIGN

A mixed-methods study using survey research and focus groups.

SETTING

Online survey and virtual focus groups.

PARTICIPANTS

Occupational therapists and SLPs who identified as clinicians who treat PFDs.

RESULTS

The survey revealed that 65% of the clinicians (N = 445) used a nonstandardized assessment tool across the four domains of PFD. The focus groups (n = 26) revealed four resulting themes that expanded the survey results: (1) no one assessment tool works, (2) clinicians rely on self-created assessments, (3) it takes a team and collaboration, and (4) there are many issues with the current assessment of PFD.

CONCLUSIONS AND RELEVANCE

This study reveals the need for clinicians working with children with PFD to use feeding assessment tools with sound psychometric properties. The requirement for occupational therapists and SLPs to evaluate and treat dysphagia and disorders of feeding indicates the need to provide entry-level education on reliable and valid assessment tools that thoroughly evaluate all the domains of PFD. What This Article Adds: This article highlights current assessment tools used by occupational therapists and SLPs treating PFD and the need for more standardized procedures and tools to evaluate children across the four domains of PFD.

Safety, feasibility and diagnostic value of Clinical Swallow Examination and FEES in children between 0 and 24 months

BACKGROUND

Clinical Swallowing Examination (CSE) and Fiberoptic Endoscopic Evaluation of Swallowing (FEES) are relevant diagnostic methods in pediatric dysphagia. Satisfactory and comprehensive healthcare is still not part of the standard diagnostic process.

AIMS

The purpose of this article is to evaluate the safety, feasibility, and diagnostic value of CSE and FEES in children 0-24 months of age.

STUDY DESIGN

A retrospective cross-sectional study which was conducted at the pediatric clinic of the University Hospital Düsseldorf, Germany, between 2013 and 2021.

SUBJECTS

A total of 79 infants and toddlers with suspected dysphagia were included.

OUTCOME MEASURES

Analyses of the cohort and FEES pathologies were performed. Dropout criterion, complications and change of diet were recorded. Chi-square identified associations between clinical symptoms and FEES results.

RESULTS

All FEES examinations were performed without complications and with a completion rate of 93.7 %. Anatomical abnormalities in the laryngeal region were diagnosed in 33 children. Wet voice was significantly associated with premature spillage (p = .028).

CONCLUSIONS

CSE and FEES are important and uncomplicated examinations for children with suspected dysphagia between 0 and 24 months. They are equally helpful for differential diagnosis of feeding disorders and anatomical abnormalities. The results underline the added value of combining both examinations and their importance for individual nutritional management. History taking and CSE are mandatory as they reflect the everyday eating situation. This study adds essential knowledge to the diagnostic work-up of dysphagic infants and toddlers. Standardizing the examinations and validating dysphagia scales are future tasks.

Development and Pilot Study of a Pediatric Screening for Feeding and Swallowing Disorders in Infants and Children: The Pediatric Screening–Priority Evaluation Dysphagia (PS–PED)

Feeding and swallowing disorders (FSD) are common during childhood, with a prevalence of 85% in children with neurodevelopmental disorders. A comprehensive screening is essential to identify FSD and improve health outcomes in a clinical setting. This study aims to develop a new Pediatric Screening tool capable of identifying FSD. This screening tool was developed in three steps: selecting variables based on clinical experience, searching the literature and finding agreement between experts with a two-round Delphi study. This process, which reached 97% of agreement between experts, led to the development of the Pediatric Screening–Priority Evaluation Dysphagia (PS–PED). PS–PED comprises 14 items divided into three main domains: clinical history, health status and feeding condition. We also carried out a pilot test for measuring internal consistency, as measured with Cronbach Coefficient alpha. Concurrent validity, as measured with Pearson correlation coefficient, was tested using a videofluoroscopy swallow study (VFSS) classified with the Penetration Aspiration Scale (PAS). The pilot test was conducted on 59 children with different health conditions. Our findings showed good internal consistency (alpha = 0.731), and a strong linear correlation with PAS (Pearson 0.824). Furthermore, comparing PS–PED and PAS scores, we find preliminary strong discriminant validity to identify children with FSD (p < 0.01). Our results provide evidence on using the 14-item PS–PED as a screening tool for FSD in a clinical sample of children with heterogeneous disease.

Predicting the clinical trajectory of feeding and swallowing abilities in CHARGE syndrome

To date, the feeding and oral-motor abilities of patients with CHARGE syndrome (CS) have not been longitudinally assessed. This study aims to investigate the level of these abilities at different ages and evaluate how they evolve during growth. We retrospectively analysed oral-motor features of 16 patients with molecularly confirmed CS (age range 4-21 years old; mean 11 years; SD 6 years; median 10 years). Nearly 100% of CS new-borns had weak sucking at birth, and half of them demonstrated poor coordination between breathing and swallowing. Over time, the percentages of children with tube feeding dependence (60% at birth) faced a slow but steady decrease (from 33% at 6 months, 25% at 12 months, to 13% at school age) in tandem with the decreasing risk of aspiration. The ability of eating foods requiring chewing was achieved at school age, after the acquisition of an adequate oral sensory processing. A mature chewing pattern with a variety of food textures was not achieved by more than half of patients, including those requiring artificial enteral nutrition. Most patients started prolonged oral-motor treatments with speech language therapists in early childhood.

CONCLUSIONS

Although feeding and swallowing disorders are constant features in CS patients, a slow and gradual development of feeding abilities occurs in most cases. Rehabilitation plays a key role in overcoming structural and functional difficulties and attaining appropriate eating skills.

WHAT IS KNOWN

• Feeding problems and swallowing dysfunction have been noted in CHARGE syndrome. • The involvement of multiple factors, including structural problems in the mouth, throat, or esophagus, and neurological impairment, make feeding a complicated task in CHARGE individuals.

WHAT IS NEW

• Dysphagia gradually improves in most CHARGE children over time, though with a wide interindividual variability. • The percentages of children with tube feeding dependence decrease over time from 60% at birth to 33% at 6 months and 13% at school age.

Pediatric Dysphagia: A Look Into the Training Received During Graduate Speech-Language Pathology Programs to Support This Population

PURPOSE

The purpose of this study was to examine academic preparation in pediatric swallowing and feeding, specifically, how speech-language pathology graduate programs were addressing pediatric swallowing and feeding, both academically and clinically, prior to guideline changes and modifications in 2020 due to updates and the global health pandemic.

METHOD

To gain a rounded image of speech-language pathology academic programs, two different methodological approaches were utilized. First, courses from 272 accredited programs were analyzed. Second, survey results from 100 participants were analyzed to investigate clinical clock hours and experiences received during participation in a graduate speech-language pathology academic program.

RESULTS

Less than 1% (0.4%) of academic courses analyzed were categorized as pediatric swallowing and feeding. Greater than 90% of participants reported receiving 20 hr or less in pediatric dysphagia, assessment, or treatment. Sixty percent of participants reported not feeling well prepared at all to provide pediatric swallowing and feeding services.

CONCLUSIONS

There are a growing number of children requiring swallowing and feeding services, a trend that looks to continue its rise. Pediatric dysphagia is a complex area requiring unique knowledge and skills. Academic programs have a responsibility to their students, and the individuals requiring speech-language pathology services, to provide experiences that allow for knowledge and skill development across the entire scope of practice and life span.

Alterations in deglutition in children with congenital Zika virus syndrome

PURPOSE

To characterize swallowing in children with congenital Zika virus syndrome in comparison to typical children.

METHODS

This cross-sectional study enrolled 45 children diagnosed with congenital Zika virus syndrome and 45 others with typical development. Swallowing was evaluated through clinical feeding evaluations Protocolo de Avaliação Clínica da Disfagia Pediátrica and using acoustic swallowing parameters (Doppler sonar).

RESULTS

The mean age of children with congenital Zika virus syndrome was 26.69 ± 4.46 months and the mean head circumference was 29.20 ± 1.98 cm. Moderate/severe oropharyngeal dysphagia was found in 32(71.1%) of the children with congenital Zika virus syndrome. Significant differences were found between the groups on clinical evaluation: Children with congenital Zika virus syndrome presented insufficient lip closure 42(93.3%) and altered tonus of the tongue 35(77.8%) and cheeks 34(75.6%). In the children in the comparison group, only 6(13.3%) presented insufficient lip closure and 1(2.2%) had inadequate tongue posture. Changes during swallowing with liquid and spoonable food were not observed in the comparison group. When liquid/food was offered, affected children presented difficulties in sipping movements 14(77.8%) and lip/spoon contact 35(75%). The presence of residual food in the oral cavity after swallowing 38(86.4%) and clinical signs indicative of laryngotracheal penetration/aspiration, such as coughing, gagging and/or labored breathing, were also notable. No differences were found between the groups with regard to the acoustic parameters evaluated instrumentally.

CONCLUSION

Children with congenital Zika virus syndrome present alterations in the oral phase of swallowing, as well as clinical signs indicative of pharyngeal phase impairment.

Assessment and management of feeding difficulties for infants with complex CHD

Early surgical intervention in infants with complex CHD results in significant disruptions to their respiratory, gastrointestinal, and nervous systems, which are all instrumental to the development of safe and efficient oral feeding skills. Standardised assessments or treatment protocols are not currently available for this unique population, requiring the clinician to rely on knowledge based on neonatal literature. Clinicians need to be skilled at evaluating and analysing these systems to develop an appropriate treatment plan to improve oral feeding skill and safety, while considering post-operative recovery in the infant with complex CHD. Supporting the family to re-establish their parental role during the hospitalisation and upon discharge is critical to reducing parental stress and oral feeding success.

Non-Pharmacological and Non-Surgical Feeding Interventions for Hospitalized Infants with Pediatric Feeding Disorder: A Scoping Review

Infants born prematurely or with complex medical conditions often require treatment to facilitate safe and efficient feeding. Practice is based on evidence, so frontline clinicians look to the literature to make informed clinical decisions. The aim of this scoping review was to map and describe the literature base for infant feeding and swallowing interventions and to identify areas for further research. Four electronic databases were searched from the sources' inceptions through April 2020 using a search strategy designed by a health sciences research librarian. Thirteen grey literature sources were searched and forward and backward citation chasing was performed. Inclusion criteria were English-language studies reporting non-pharmacological and non-surgical interventions for hospitalized infants. Exclusion criteria included interventions exclusively for infants with cleft lip or palate or for infants being fed exclusively though enteral feeding. Data were extracted using a form created a priori and data were reported descriptively. We reviewed 6654 abstracts: 725 were chosen for full-text review and 136 met inclusion. Most studies explored interventions for infants born prematurely (n = 128). Studies were stratified by intervention domain: bridging (n = 91) and feeding/swallowing (n = 45); intervention approach: direct (n = 72), indirect (n = 31), or combination (n = 33); and outcome: feeding performance (n = 125), physiologic stability (n = 40), and swallowing physiology (n = 12). The body of research in infant feeding has grown; however, a need remains for research focused on populations of infants with various medical complexities and for frequently used interventions that lack supporting evidence.

Eating and drinking ability and nutritional status in adults with cerebral palsy

AIM

To describe eating and drinking ability in adults with cerebral palsy (CP) relative to sex, age, subtype, and severity of gross motor and hand function and nutritional status.

METHOD

This was a cross-sectional study based on data of 2035 adults with CP, median age 26 years (range 18-78 years). The Eating and Drinking Ability Classification System (EDACS), Gross Motor Function Classification System (GMFCS), and Manual Ability Classification System (MACS) were used in addition to subtype, body weight, height, body mass index (BMI), skin fold thickness, and gastrostomy. Linear regression models were used to estimate associations between body weight and the other variables.

RESULTS

More than half of the adults (52.5%) eat and drink safely and 32.4% have dysphagia with limitations to eating and drinking safety. Weight, height, and BMI decreased with increasing EDACS levels. In EDACS level V, 86% had a gastrostomy, 23.4% in EDACS levels III to V were underweight, whereas 42.3% in EDACS levels I to II had a BMI over 25, indicating overweight or obesity. Increasing EDACS levels and need of support during meals were associated with lower body weight.

INTERPRETATION

Adults with CP should be routinely screened and treated for dysphagia to avoid nutritional complications. Being dependent on others during mealtimes is a risk factor for low body weight.

Clinical Focus: Findings and Clinical Implications for Thickening Formula With Infant Cereal Using the International Dysphagia Diet Standardisation Initiative Flow Test

PURPOSE

The International Dysphagia Diet Standardisation Initiative (IDDSI) framework was established to provide standardized terminology and objective measures to assess foods and liquids for persons with swallowing difficulties. This clinical focus article reports the findings and clinical implications of the flow testing of infant formulas thickened with infant cereal completed as part of the transition process to IDDSI for one large pediatric quaternary care hospital.

METHOD

To determine a common recipe that could be used to thicken formulas with infant cereal to the appropriate IDDSI levels, three clinicians completed flow testing on 94 infant formulas. To examine intra- and interclinician variability in the process, they repeated flow testing with three commonly used formulas and infant cereal.

RESULTS

Clinicians were unable to identify a standard recipe (infant formula + infant cereal combination) that consistently thickened different formula brands to a desired IDDSI thickness level, as there was pronounced variability across and within infant formulas. Reliability testing revealed that, overall, clinician mixers were consistent in replicating similar results to themselves and to each other and that, instead, greater variability lies within the formula (and infant formula + infant cereal combination).

CONCLUSIONS

Based on findings of pronounced variability within and across infant formulas, our institution determined that the creation of a standard recipe for achieving IDDSI thickness levels of formula mixed with infant cereal was not feasible or clinically appropriate. We offer recommendations for similar institutions for advancing clinical management of infant dysphagia using the IDDSI flow test and directions for future research.

Videofluoroscopy compared with clinical feeding evaluation in children with suspected aspiration

Aim

Videofluoroscopy swallow studies (VFSS) are gold standard to diagnose aspiration in children but require resources and radiation compared with clinical feeding evaluation (CFE). We evaluated their added value for diagnosis, feeding management and clinical status.

Methods

A retrospective single‐centre cross‐sectional study of children aged 0–18 years, with respiratory morbidity, referred for VFSS at a tertiary pediatric hospital.

Results

A total of 113 children, median age (range) 2.2 years (0.1–17.9), underwent VFSS. Diagnosis included chronic pulmonary aspiration (CPA), 87 (77%); neurological, 73 (64%); gastrointestinal, 73 (64%) and congenital heart disease, 42 (37%), not mutually exclusive. Forty‐six (41%) aspirated, 9 (8%) only overtly and 37 (33%) including silent aspirations. Those with CPA or cerebral palsy were more likely to have VFSS aspiration, OR 3.2 and 9.8 respectively.

Feeding recommendations after VFSS differed significantly from those based on prior CFE, p < 0.001: The rate of exclusively orally fed children rose from 65% to 79%, p = 0.006; exclusively enterally fed children from 10% to 14%; p = 0.005. During the year after VFSS, there were significantly less antibiotic courses, total and respiratory admissions.

Conclusion

In this population with high prevalence of clinically suspected CPA, VFSS altered feeding management compared with CFE and may have contributed to subsequent clinical improvement.

Prevalence of dysphagia symptoms in Cretan children and adolescents with neurological disorders

Objectives

Dysphagia is defined as any feeding or swallowing dysfunction at one or more stages of digestion. This study aims to investigate the prevalence of dysphagia symptoms in children and adolescents with neurological disorders and its relationship with the specific characteristics of the subjects.

Methods

Using data from general hospital/paediatric department visits in Heraklion, Crete, Greece, a cross-sectional study design was implemented over a seven-month period (2017-18), and a total of 268 children and adolescents were recruited. Demographic data and medical profiles were recorded, focusing on the most obvious and frequent clinical features of feeding and swallowing disorders per stage (oral-OS, pharyngeal-PS, and oesophageal-ES).

Results

In the sample, 54.9% were boys and the mean age was 5.9 years; the most prevalent International Statistical Classification of Diseases and Related Health Problems (ICD-10) disorder was mental and behavioural disorders (37.3%). The prevalence of dysphagia symptoms was 24.3% during the OS (95% CI: 19.0-29.9), 18.3% in the PS (95% CI: 14.0-23.2), and 20.1% in the ES (95% CI: 15.7-25.4). At least one symptom of dysphagia was observed during the OS, PS, and ES in 42.5% (95% CI: 36.7-48.5) of the sample. The presence of dysphagia seems to be related to lower age (Odds Ratio [OR] = 0.45, p < 0.001), higher ICD-10 comorbidity (OR = 1.89, p < 0.05), or medication use (OR = 2.31, p < 0.05).

Conclusions

A high prevalence of dysphagia was found in children and adolescents with neurological disorders, while lower age, comorbidity, and medication use emerged as factors that required better management.

Developing a Protocol for Quantitative Analysis of Liquid Swallowing in Children

PURPOSE

Objective measures in videofluoroscopic swallow studies (VFSSs) can quantify swallow biomechanics. There are a wide array of validated measures studied in infants, children, and adults. There is a need for a pediatric VFSS protocol that consists of a small number of vital, time efficient, and clinically relevant measures. In this study, we aimed to establish a standard protocol for quantitative VFSS analysis in children.

METHOD

Protocol development began with a systematic literature review, which identified 22 quantitative and eight descriptive measures available in the literature. A pediatric VFSS database of 553 children was collected using a standardized VFSS protocol. Studies were evaluated using the 30 previously reported measures covering displacement and timing parameters as well as penetration-aspiration and residue. Measures were tested for rater reliability and internal consistency. Measures meeting acceptable values for protocol inclusion were included in the final protocol (Cronbach's alpha > .53).

RESULTS

Interrater and intrarater reliability of 17 measures met acceptable reliability levels. During internal consistency testing, we removed six further measures based on Cronbach's alpha levels indicating that two or more measures were equivalent in measuring the same aspect of swallow biomechanics in children. A VFSS protocol of reliable, valid, and obtainable objective quantitative (n = 6) and descriptive measures (n = 3) with separate protocols for young infants (≤ 9 months) and older children was established.

CONCLUSIONS

A standardized quantitative VFSS protocol for children has been developed to suit two age groups (≤ 9 and > 9 months old). Consistent VFSS administration and reporting support assessment over time and across disease groups. Future research should focus on how this information can be used by clinicians to produce individualized treatment plans for children with swallowing impairment.

Conceptual Framework Behind the Development of a Level of Confidence Tool: The Pediatric Videofluoroscopic Swallow Study Value Scale

PURPOSE

The videofluoroscopic swallow study (VFSS) is the most commonly used instrumental procedure for evaluating swallowing in pediatric populations suspected of having dysphagia. Assessment and interpretation of a VFSS in pediatric populations is frequently challenged by testing-specific factors that can raise concerns regarding the representativeness of swallow events observed during testing compared to daily feeding/swallowing physiology. When VFSS findings do not represent typical swallowing patterns, treatment recommendations can result in suboptimal outcomes. To address this current challenge to pediatric VFSS interpretation and associated treatment recommendations, the pediatric VFSS Value Scale (pVFSS Value Scale) was developed within a tertiary regional pediatric medical center. This clinical focus article summarizes the initial scale development phases and resulting conceptual framework for rating clinical testing factors that influence a clinician's level of confidence regarding pediatric VFSS findings. Future goals for scientific evaluation and clinical utilization of this new rating scale are also reported.

CONCLUSIONS

The pVFSS Value Scale was developed to assist clinicians with interpretation of pediatric VFSS assessment outcomes and to efficiently communicate factors influencing impressions and treatment recommendations with team members and caregivers. This clinical concept article summarizes potential uses of this tool to inform treatment planning as well as future clinical research to evaluate its psychometrics and clinical utility.

L, González G. S. Instrumentos de evaluación de la deglución pediátrica: un reporte por fonoaudiólogos en Colombia y Chile

La prevalencia de usuarios pediátricos que presentan alteraciones en la deglución/ alimentación ha aumentado significativamente, por lo que realizar un proceso de evaluación sistemático, a usuarios ambulatorios y/u hospitalizados, con el uso de instrumentos estandarizados, puede evitar complicaciones asociadas. El objetivo de esta investigación fue identificar cuáles son las pruebas que conocen y usan los fonoaudiólogos en dos países de habla hispana: Colombia y Chile, para la valoración de la deglución en población pediátrica. Se trata de un estudio observacional de corte transversal, en el que participaron 36 fonoaudiólogos de ambos países, los que contestaron una encuesta de 23 ítems, previamente validada por juicio de expertos. El 55,6% (n=20) señaló que conocía pruebas de screening, el 63,89% (n=23) conocía pruebas de evaluación clínica (no instrumentales o subjetivas), el 100% conocía pruebas instrumentales (objetivas) y sólo el 11% (n=4) conocían pruebas de calidad de vida. Se evidenció de forma general dificultad en la clasificación de las pruebas y un mayor uso de pruebas no estandarizadas, lo que sugiere una necesidad disciplinar en cuanto a la formación sobre instrumentos de medición y evaluación, que permitan la identificación, selección y comprensión analítica de dichos instrumentos.

Using an Automated Speech Recognition Approach to Differentiate Between Normal and Aspirating Swallowing Sounds Recorded from Digital Cervical Auscultation in Children

Use of machine learning to accurately detect aspirating swallowing sounds in children is an evolving field. Previously reported classifiers for the detection of aspirating swallowing sounds in children have reported sensitivities between 79 and 89%. This study aimed to investigate the accuracy of using an automatic speaker recognition approach to differentiate between normal and aspirating swallowing sounds recorded from digital cervical auscultation in children. We analysed 106 normal swallows from 23 healthy children (median 13 months; 52.1% male) and 18 aspirating swallows from 18 children (median 10.5 months; 61.1% male) who underwent concurrent videofluoroscopic swallow studies with digital cervical auscultation. All swallowing sounds were on thin fluids. A support vector machine classifier with a polynomial kernel was trained on feature vectors that comprised the mean and standard deviation of spectral subband centroids extracted from each swallowing sound in the training set. The trained support vector machine was then used to classify swallowing sounds in the test set. We found high accuracy in the differentiation of aspirating and normal swallowing sounds with 98% overall accuracy. Sensitivity for the detection of aspiration and normal swallowing sounds were 89% and 100%, respectively. There were consistent differences in time, power spectral density and spectral subband centroid features between aspirating and normal swallowing sounds in children. This study provides preliminary research evidence that aspirating and normal swallowing sounds in children can be differentiated accurately using machine learning techniques.

Feeding Problems and Long-Term Outcomes in Preterm Infants—A Systematic Approach to Evaluation and Management

Preterm infants are known to have long-term healthcare needs. With advances in neonatal medical care, younger and more preterm infants are surviving, placing a subset of the general population at risk of long-term healthcare needs. Oral feeding problems in this population often play a substantial yet under-appreciated role. Oral feeding competency in preterm infants is deemed an essential requirement for hospital discharge. Despite achieving discharge readiness, feeding problems persist into childhood and can have a residual impact into adulthood. The early diagnosis and management of feeding problems are essential requisites to mitigate any potential long-term challenges in preterm-born adults. This review provides an overview of the physiology of swallowing and oral feeding skills, disruptions to oral feeding in preterm infants, the outcomes of preterm infants with feeding problems, and an algorithmic approach to the evaluation and management of neonatal feeding problems.

Systematic review of validated parent-reported questionnaires assessing swallowing dysfunction in otherwise healthy infants and toddlers

OBJECTIVES

There has been increasing interest in the management of oropharyngeal swallowing dysfunction (SwD). Its prevalence, particularly in otherwise healthy infants and toddlers (OHITs), is underappreciated. As the standard diagnostic tests are either invasive or scarce, valid parent-reported outcome (PRO) questionnaires could play a pivotal role in the understanding and managing SwD in this group. This article reviewed the literature on PRO questionnaires pertaining to SwD in OHITs.

DATA SOURCE

A librarian searched Prospero, Cochrane Library, Embase, Medline, PsycINFO, HaPI, CINAHL, and SCOPUS until February 2021 using the MeSH terms for deglutition and screening methods.

REVIEW METHOD

Questionnaires that examined disease-specific or eating and feeding concerns or difficulties were excluded. Two reviewers independently identified PRO questionnaires for SwD that were used in OHITs and extracted the author names, publication year, questionnaire name, the studied population, and the reported psychometric assessments. A quality assessment was performed based on consensus-based standards for the selection of health measurement instruments (COSMIN) and updated criteria for good measurement properties.

RESULTS

Of the 3488 screened articles, we identified only two questionnaires, the pediatric version of the Eating Assessment Tool (PEDI-EAT-10) and the PRO questionnaire for Swallowing Dysfunction in OHITs. The PEDI-EAT-10 authors assessed the validity and reliability on children with cerebral palsy. However, concerns were identified regarding the developmental process and the internal structure validity. The PRO questionnaire for SwD in OHITs meets criteria but has not yet been validated in the population of interest nor its psychometric properties assessed.

CONCLUSION

Two instruments were identified. The PED-EAT-10 exhibits methodological flaws, while Edmonton PRO questionnaire for SwD in OHITs awaits construct validation and could fill the current knowledge gap.

Association between Swallowing-Related Questionnaire Responses and Pathological Signs on Videofluoroscopy in Children

The aim of this study was to identify relationships in children between responses to specific questions of interest in a clinical questionnaire concerning swallowing-related difficulties and pathological signs on a videofluoroscopic swallowing study (VFSS). A prospective data analysis was made of children evaluated with swallowing disorder between January 2018 and April 2021 at a tertiary care centre. Each child enrolled in the study underwent a subjective evaluation (targeted questions) and instrumental examination (VFSS). In total, 51 children suffering from swallowing problems (32 with a neurological disorder and 19 without neurological disorder) were included into the study. Our results showed there was a correlation between the occurrence of specific symptoms (wet voice, wet breathing, recurrent respiratory infections, chronic mucus) and other pathological signs on a VFSS (laryngeal penetration, residua, nasal regurgitation). The evaluation of these specific questions is a reliable and useful method for the management of dysphagia in neonates and infants. It can help us in selecting those patients for which it is appropriate to perform a VFSS.

Translation, Cultural Adaptation, Reliability, and Validity Evidence of the Feeding/Swallowing Impact Survey (FS-IS) to Brazilian Portuguese

The purpose of this study was to translate and adapt the Feeding/Swallowing Impact Survey (FS-IS) into Brazilian Portuguese and provide a validated instrument for caregivers of children with feeding/swallowing disorders. This cross-cultural study involved initial translation, synthesis of translations, back-translation, Committee of Experts, and pre-test. The sample consisted of 95 primary caregivers of children with feeding/swallowing disorders classified by Pediatric Dysphagia Evaluation Protocol (PDEP) in mild (n = 9), moderate-severe (n = 40), or profound (n = 46) dysphagia. Reliability and evidence of validity based on test content, response processes, internal structure and the relations to other variables were investigated. Internal consistency, test-retest, exploratory and confirmatory factor analysis were performed, in addition to the correlation with PedsQL™ Family Impact Module (PedsQL^TMFIM). The pre-test participants did not report any difficulties in understanding the translated version. The Brazilian Portuguese version of FS-IS (Pt-Br-FS-IS) presented Cronbach's Alpha of 0.83, Exploratory Factor Analysis verified that the instrument would not be unifactorial (KMO = 0.74 and Bartlett's sphericity test p < 0.001) and Confirmatory Factor Analysis confirmed the original model in three subscales with χ²/df = 1.23, CFI = 0.92, TLI = 0.90, RMSEA (90% CI) 0.049 (0.011-0.073) adjustment indexes and the ICC was excellent in all subscales and total score. The correlation with PedsQL™FIM was significant in the total score and subscales. This study successfully translated and cross-culturally adapted the FS-IS instrument to the Brazilian Portuguese language and the investigation of its reliability and validity evidence suggests that the Pt-Br-FS-IS is a reliable and valid tool to measure the impact of feeding/swallowing disorders on the quality of life of caregivers of affected children.

Instrumental Swallowing Assessments in the Neonatal and Pediatric Populations: A Systematic Review

The scientific scope of swallowing disorders in the neonatal and pediatric populations is growing exponentially; however, the preponderance of evidence for evaluation protocols has been concentrated in non-instrumental evaluations creating a lack of research about protocols for instrumental swallowing assessment. Thus, the purpose of this study was to systematically review the literature to identify and to report protocols used in instrumental assessments through videofluoroscopic swallow study (VFSS) and fiberoptic endoscopic evaluation of swallowing (FEES) in the neonatal and pediatric populations to support clinical decision making. The search strategy was applied in five online databases, no filters were applied to restrict languages or publication dates and the gray literature was reviewed. PRISMA statement was used to guide the construction of this review. The studies included validated and unvalidated protocols, the validated protocols had their risk of bias estimated using the QUADAS-2. In total, 13 studies were included in the final review, of these eleven assessed through QUADAS-2, and two classified with low risk of bias. One study is in the process of standardization and validation of an instrumental assessment protocol for swallowing in bottle-fed infants through VFSS. Information about validity and reliability of published protocols for instrumental evaluation in the neonatal and pediatric populations is limited. Therefore, further research is needs to development studies aiming to standardize and validate protocols for instrumental assessments in these populations.

Clinical and videofluoroscopic evaluation of feeding and swallowing in infants with oropharyngeal dysphagia

BACKGROUND

Dysphagia impacts infants' health and well-being and may result in aspiration pneumonia.

OBJECTIVE

This study aimed to evaluate feeding and swallowing functions in infants with dysphagia to determine the possible causes of dysphagia and their relationship with the medical diagnoses. Clinical and videofluoroscopic findings were compared to determine the diagnostic accuracy of clinical evaluation and identify clinical predictors of laryngeal penetration and aspiration.

METHODS

This study was conducted on 60 infants in the age range 2-19 months (median seven months) with suspected aspiration and/or feeding problems. All cases were subjected to both clinical and videofluoroscopic evaluation of swallowing.

RESULTS

The two most frequently observed videofluoroscopic findings were aspiration and suck-swallow-breathing incoordination. Infants with structural laryngeal abnormalities were significantly more likely to experience aspiration. A significant association was found between the presence of aspiration and the presence of both recurrent chest infection and gurgly voice combined, which increased the risk of aspiration by 3.57 times. However, the presence of gagging alone and gagging combined with a recurrent chest infection significantly reduced the risk of aspiration. The clinical assessment accuracy presented 56.70%, with 55.60% sensitivity, 58.30% specificity, and a positive predictive value higher than the negative.

CONCLUSION

The study highlights the importance of complementing clinical evaluation, in infants with dysphagia, with an objective evaluation of swallowing such as videofluoroscopy due to the high proportion of false positives noticed in clinical evaluation and the high prevalence of silent aspiration in infants.

Laryngeal cleft: A literature review

INTRODUCTION

Laryngeal cleft is a congenital condition in which an opening in the posterior laryngotracheal wall allows food and liquid to pass from the esophageal lumen to the airway and causes aspiration. The severity of a laryngeal cleft is measured using the Benjamin-Inglis system, and can be managed conservatively or with a variety of surgical options With increased awareness, higher suspicion among primary physicians, advanced technology and improved intensive neonatal care services, more babies with laryngeal clefts survive in the modern era. Therefore, the focus has shifted from infant survival to treatment of laryngeal clefts and the challenging, complex medical conditions they create.

OBJECTIVE

To understand current laryngeal cleft management and post-operative outcomes.

METHODS

Literature review of laryngeal cleft studies from 2010 to 2021.

RESULTS

A total of 1033 patients were included. Based on 415 cases for whom sufficient classification data were available, the predominate symptom for patients with type I, III, and IV clefts is swallowing dysfunction, while the predominant symptoms for patients with type II clefts are stridor and aspiration. A wide variety of comorbidities involving several major organs has been reported with laryngeal clefts, which tend to impact clinical outcomes negatively. Approximately 19% of type I clefts have been treated conservatively successfully, but the majority was treated surgically. Most studies that used injection laryngoplasty for type I clefts reported highly successful repairs without complications or delays in additional procedures. Ninety-eight percent all type II clefts were treated with endoscopic repair; 87% of patients with type III clefts received endoscopic repair; and 66% of patients with type IV clefts underwent open surgery. Approximately 62% of resolved cases were reported within 12 months, while 50.87% of failed cases were reported within 6 weeks.

CONCLUSIONS

There are multiple treatment approaches, each of which may be applicable depending on factors such as laryngeal cleft type, severity of presentation, and comorbidities. Conservative approaches appear to be most useful for type I clefts or in patients with mild symptoms, while surgical management can be considered for any type of laryngeal cleft. The benefit of injection laryngoplasty, endoscopic repair and open surgery can also vary, but injection laryngoplasty and endoscopic repair are used most commonly. Open surgery should be to be considered if patients present with severe cleft types or if it is unsafe to perform other surgical techniques. Familiarity with this literature review should help clinicians understand clinical characteristics, direct medical management, and guide successful resolution of laryngeal clefts.

Evaluating the Use of Telepractice for Bottle-Feeding Assessments

There is currently limited evidence supporting the use of telepractice to conduct bottle-feeding assessments. This study aimed to investigate the inter-rater reliability of bottle-feeding assessments conducted via synchronous telepractice (real-time videoconferencing). Secondary aims were to investigate parent and clinician satisfaction. Bottle-feeding skills of 30 children (aged 1 month-2 years) were simultaneously assessed by a telepractice SP (T-SP) at a remote location and an in-person SP (IP-SP) at the family home. A purpose-designed assessment form was used to evaluate: (1) developmental level (screen only), (2) state, color, and respiration, (3) oral motor skills, (4), infant oral reflexes, (5) tongue tie (screen only), (6) non-nutritive suck, (7) bottle-feeding, (8) overall feeding skills and (9) recommendations. Results of the T-SP and IP-SP assessments were compared using agreement statistics. Parents reported perceptions of telepractice pre and post session, and also rated post-session satisfaction. The telepractice SP completed a satisfaction questionnaire post-appointment. The majority of assessment components (45/53, 85%) met the agreement criteria (≥80% exact agreement). Difficulties were noted for the assessment of palate integrity, gagging during non-nutritive suck assessment, and 6 components of the tongue tie screen. Parent and clinician satisfaction was high; SPs reported that they would offer telepractice services to 93% of families again in the future. Overall, the results demonstrated that most components of a bottle-feeding assessment could be reliably completed via synchronous telepractice in family homes. However, further research is required to improve the reliability of some intra-oral assessment components.

Paediatric oral sensorimotor interventions for chewing dysfunction: A scoping review

BACKGROUND

Chewing dysfunction can have adverse effects on growth, development and quality of life. There is a lack of evidence-based consensus guidelines for sensorimotor intervention. To address this, we need to understand the current state of the science in clinical sensorimotor interventions for paediatric chewing dysfunction and systematically plan a research agenda and priorities for the field.

AIMS

The purpose of this scoping review was to examine the extent, range and nature of evidence for oral sensorimotor interventions for paediatric chewing dysfunction.

METHODS & PROCEDURES

This scoping review entailed five phases that included: identification of the research question; identification of relevant studies; study selection; data charting; and collation, summarization and report of the results. Treatment studies that were peer-reviewed and written in English were included. All studies involved a paediatric population and included an oral sensorimotor and/or chewing intervention. Information regarding study design, population, intervention, comparator, outcome measures and findings were extracted.

MAIN CONTRIBUTION

Of the 21 studies included in this scoping review, 53% were specific to children with cerebral palsy. All interventions were multi-component in nature and the treatment studies included a range of study designs, but few were controlled trials with comparators. A wide variety of outcomes measures were used within and across studies to determine treatment effectiveness.

CONCLUSIONS & IMPLICATIONS

The findings suggest that in a small number of studies, sensorimotor interventions provide preliminary evidence for effectiveness in specific populations. These and other treatment protocols must be trialled in additional clinical populations and settings to improve the evidence base for sensorimotor treatment of paediatric chewing dysfunction. This review also serves to help prioritize research agendas and further motivates the need for consensus-based clinical guidelines for paediatric chewing treatment.

WHAT THIS PAPER ADDS

What is already known on the subject Paediatric feeding disorders are highly prevalent and children often have chewing dysfunction that results in significant negative consequences. We lack evidence-based sensorimotor treatment approaches for chewing dysfunction, which directly impacts the care clinicians can provide children. What this study adds to existing knowledge This scoping review is the first step in examining the literature to understand the current state of the science for oral sensorimotor interventions for paediatric chewing dysfunction. Few randomized controlled studies were identified and a majority included children with cerebral palsy. Most of the interventions were multi-component and included a variety of treatment approaches. What are the potential or actual clinical implications of this work? The results of this scoping review can be used as an initial reference for clinicians selecting treatment approaches for chewing dysfunction. It also serves to help prioritize research agendas and further motivates the need for consensus-based clinical guidelines for paediatric chewing treatment.

Mechanisms and management considerations of parent-chosen feeding approaches to infants with swallowing difficulties: an observational study

Videofluoroscopy swallow studies (VFSS) and high-resolution manometry (HRM) methods complement to ascertain mechanisms of infant feeding difficulties. We hypothesized that: (a) an integrated approach (study: parent-preferred feeding therapy based on VFSS and HRM) is superior to the standard-of-care (control: provider-prescribed feeding therapy based on VFSS), and (b) motility characteristics are distinct in infants with penetration or aspiration defined as penetration-aspiration scale (PAS) score ≥ 2. Feeding therapies were nipple flow, fluid thickness, or no modification. Clinical outcomes were oral-feeding success (primary), length of hospital stay and growth velocity. Basal and adaptive HRM motility characteristics were analyzed for study infants. Oral feeding success was 85% [76-94%] in study (N = 60) vs. 63% [50-77%] in control (N = 49), p = 0.008. Hospital-stay and growth velocity did not differ between approaches or PAS ≥ 2 (all P > 0.05). In study infants with PAS ≥ 2, motility metrics differed for increased deglutition apnea during interphase (p = 0.02), symptoms with pharyngeal stimulation (p = 0.02) and decreased distal esophageal contractility (p = 0.004) with barium. In conclusion, an integrated approach with parent-preferred therapy based on mechanistic understanding of VFSS and HRM metrics improves oral feeding outcomes despite the evidence of penetration or aspiration. Implementation of new knowledge of physiology of swallowing and airway protection may be contributory to our findings.

Infant aspiration and associated signs on clinical feeding evaluation

OBJECTIVES

Few studies have examined clinical signs of aspiration in infants <51 weeks post-menstrual age (PMA) for whom the laryngeal cough reflex is not fully developed. This retrospective study explored 1) the association between signs of aspiration on a clinical feeding evaluation (CFE) and/or comorbid conditions with aspiration (silent or overt) on a modified barium swallow study (MBS) for infants in this age range, 2) the association between lower respiratory infection (LRI) and aspiration on MBS, and 3) the sensitivity and specificity of detecting aspiration according to signs on CFE and the evaluating speech-language pathologist's (SLP) years of experience.

METHODS

A retrospective review of charts of patients with MBS completed January 1, 2012-December 31, 2014 was performed. Patients were included if they were <51-weeks PMA at the time of MBS and had a CFE conducted no more than seven days prior to the MBS. Patient age, comorbidities, and MBS and CFE details were collected. The impact of CFE findings, patient age, comorbid syndromes/associations, and aerodigestive diagnoses on the odds of demonstrating silent aspiration (SA) or overt aspiration during MBS with thin liquids was determined using logistic regression, and the sensitivity and specificity of CFE for identifying SA was calculated.

RESULTS

Results from 114 patients indicated that 46 (40 %) of the infants had SA and nine (8 %) had overt aspiration on MBS. Notable signs on CFEs were cough (36 %), oxygen desaturations (33 %), and chest congestion (32 %). On multiple regression analysis there was increased odds of SA on MBS with at least one clinical sign on CFE (OR: 24.3, p = 0.02), chronic lung disease, (OR: 18.2, p = 0.01), and airway abnormalities (OR: 2.94, p = 0.01). Cough on CFE was associated with increased odds of overt aspiration on MBS (OR: 5.69, p = 0.04). Neither SA nor overt aspiration were significantly associated with LRI. Sensitivity and specificity of CFE for correctly identifying the presence of SA were 98 % and 15 %, respectively; experience of the SLP was not a contributing factor.

CONCLUSION

Further study is required to determine if specific signs on CFE are predictive of aspiration.

Evaluating the Use of Telepractice to Deliver Pediatric Feeding Assessments

Purpose This study aimed to investigate the interrater reliability of pediatric feeding assessments conducted via synchronous (real-time) telepractice. Secondary aims were to investigate parent and clinician satisfaction. Method The eating and/or cup drinking skills of 40 children (aged 4 months to 7 years) were simultaneously assessed by one speech-language pathologist (SLP) leading the appointment via telepractice and a second SLP present in the family home. A purpose-designed assessment form was used to assess (a) positioning, (b) development, (c) oral sensorimotor function, (d) prefeeding respiratory status, (e) observation of eating and drinking, (f) parent-child interaction, (g) overall feeding skills, and (h) feeding recommendations. The telepractice SLP completed a postappointment satisfaction questionnaire, and parents completed five questionnaires specifically investigating perceptions of and satisfaction with the telepractice feeding appointment. Results Agreement for all assessment components except intraoral examination (palate integrity and tonsils) was > 85%. All appointments were able to be conducted via telepractice, and for 90% of these (n = 36), clinicians agreed that telepractice was an effective service delivery method. Parents reported high levels of satisfaction with telepractice, with 76% reporting that the telepractice appointment was similar to a traditional in-person appointment. Conclusion Study results demonstrated that synchronous pediatric feeding assessments conducted in family homes via telepractice were feasible, reliable, and acceptable to both clinicians and parents.

Factors Associated with Feeding Problems in Young Children with Gastrointestinal Diseases

Feeding problems are associated with the consumption of a limited amount or restricted variety of foods and often occur in children with gastrointestinal diseases. The majority of studies to date do not use valid and reliable measurements to detect feeding problems. The aim of this cross-sectional study was to assess behavioral and skill-based feeding problems in young children with gastrointestinal diseases by using a well-established parent-reported feeding measure and identify demographic, anthropometric, and environmental factors associated with maladaptive feeding behaviors in this pediatric population. Parents completed the Greek version of the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) and self-reported questionnaires assessing mealtime environment and parental feeding practices. It was found that 18.6% of the sample had abnormal Total Frequency Score (TFS) (frequency of problematic feeding behaviors) and 39.5% had abnormal Total Problem Score (TPS) (number of behaviors perceived as problematic by parents). Younger children, with lower body mass index, lower birth weight, and only children were more likely to have feeding problems. The study showed that parent-reported feeding problems are increased in young children with gastrointestinal diseases and are associated with specific aspects of mealtime environment and parental feeding practices.

Occurrence of speech-language disorders in the acute phase following pediatric acquired brain injury: results from the Ghent University Hospital

AIMS

This study investigated the occurrence of speech-language disorders during the acute phase of recovery in children with acquired brain injury (ABI) with an age between 0 and 16 years.

METHODS

A retrospective chart analysis was performed including 228 children (n = 118 boys, n = 110 girls) who consecutively presented with ABI over a 10-year period (2006-2016) at the children's rehabilitation center at Ghent University Hospital. Descriptive statistical analyses were applied.

RESULTS

71.1% (162/228) of the children who were admitted to the rehabilitation center presented with a speech-language disorder. Within this sample (n = 162), results demonstrated the occurrence of acquired disorders in language (48.9%), speech (35.1%), learning (33.3%), swallowing (21.5%), and early communicative functions (17.4%). The proportion of children presenting with disturbances in early communicative functions differed by ABI cause. More than half (10/18, 58.8%) of the children who presented with ABI following inflammatory processes demonstrated disorders in early communicative functions.

CONCLUSIONS

Especially in young children who present with inflammatory processes as the ABI cause, speech-language pathologists (SLPs) must be aware of disorders in early speech-language development. The present findings allow the SLP to appropriately plan research, education, and clinical management.

What are parents' perceptions related to barriers in diagnosing swallowing dysfunction in children? A grounded theory approach

OBJECTIVES

Swallowing dysfunction (SwD) is under-reported in otherwise healthy infants and toddlers (OHITs). The identification of parental perceptions of factors that may hinder the diagnosis could help clinicians manage these children in a more expeditious manner. This study investigated the barriers to diagnosing SwD, as reported by the families.

DESIGN

Grounded theory study.

SETTING

This study was performed in a tertiary care paediatric centre in Canada.

PARTICIPANTS

Parents of OHITs were recruited using purposeful sampling.

INTERVENTION

We used detailed, semistructured, in-person interviews and the audiotapes and transcriptions were thematically analysed. From the parental insights, we built a framework composed of three themes of barriers.

RESULT

Ten parents of OHITs with SwD were interviewed. The children presented with recurrent coughing, choking, cold-like symptoms, recurring/consistent illnesses and feeding difficulties. They were managed with multiple rounds of antibiotics and diagnosed with allergies, asthma or recurrent viral infections before considering SwD. The three emerging themes are false beliefs about SwD among parents and some physicians, parent-related barriers and physician-related barriers. These barriers had severely impacted the parents, impairing work productivity and leading to work-related reprimands and changes in the family dynamics.

CONCLUSION

This study suggests that there are several barriers that face the parents of OHITs when seeking a diagnosis of SwD and initiating appropriate management. These barriers likely interact with one another and amplify their effects on the family and the child. A common denominator is a lack of education regarding SwD, its clinical manifestations and the available expertise to manage this condition.

Feeding and Swallowing Problems in Infants with Spinal Muscular Atrophy Type 1: an Observational Study

BACKGROUND

Infantile hereditary proximal spinal muscular atrophy (SMA) type 1 is characterized by onset in the first 6 months of life and severe and progressive muscle weakness. Dysphagia is a common complication but has not been studied in detail.

OBJECTIVE

To study feeding and swallowing problems in infants with SMA type 1, and to explore the relation between these problems and functional motor scores.

METHODS

We prospectively included 16 infants with SMA type 1 between September 2016 and October 2018. Eleven infants received palliative care and five infants best supportive care in combination with nusinersen. We compiled and used an observation list with feeding related issues and observed feeding sessions during inpatient and outpatient visits. The Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) was used as a measure of motor function.

RESULTS

All infants in the palliative care group (median onset of disease 14 days (range 1-56); median inclusion in the study 52 days (range 16-252) demonstrated symptoms of fatigue during feeding and unsafe swallowing. Symptoms were short nursing sessions (10-15 minutes), and not being able to finish the recommended feeding volumes (72%); increased frequency of feeding sessions (55%); coughing when drinking or eating (91%), and wet breathing during and after feeding (64%).Two out of five infants in the nusinersen group (median onset of disease 38 days (range 21-90); inclusion in the study at 63 days (range 3-218) were clinically pre-symptomatic at the start of treatment. The other three infants showed symptoms of fatigue and unsafe swallowing at inclusion in the study. These symptoms initially decreased after the start of the treatment, but (re)appeared in all five infants between the ages of 8 to 12 months, requiring the start tube of feeding. In the same period motor function scores significantly improved (median increase CHOP INTEND 16 points).

CONCLUSION

Impaired feeding and swallowing remain important complications in infants with SMA type 1 after the start of nusinersen. Improvement of motor function does not imply similar gains in bulbar function.
