Patient-Reported Outcome Measures That Describe the Feeding Skills Domain for Pediatric Feeding Disorder: A Clinimetric Review

OBJECTIVES

Pediatric feeding disorder (PFD) is defined as "impaired oral intake that is not age-appropriate, and is associated with medical, nutritional, feeding skill, and/or psychosocial dysfunction." Patient-reported outcome measures (PROMs) are tools that complement clinical assessment, but many have limited clinimetric data. This review aimed to assess PROMs that reported on the feeding skills domain for PFD in children.

METHODS

A search strategy across 4 databases was conducted (July 2022). PROMs were included in the review if they described elements of the feeding skills domain of PFD, had criterion/norm-referenced data and/or a standardized assessment procedure, description, or scoring system available, and were applicable to children ≥6 months. PROMs were mapped to the PFD diagnostic domains and aspects of the International Classification of Function (ICF) model. Quality assessment was completed using the COnsensus-based Standards to the selection of health Measurement Instruments methodology.

RESULTS

Overall, 14 PROMs across 22 papers met inclusion criteria. There was variable methodological quality across the tools, with those more recently developed often receiving better scores, particularly where a more rigorous process for tool development and content validity was reported. Most tools captured ICF aspects of impairment (n = 11, eg, biting/chewing) or activity (n = 13, eg, eating a meal), rather than social participation (n = 3, eg, going to a restaurant).

CONCLUSIONS

Using PROMs with strong content validity, and including some measure of social participation, is recommended as part of an assessment battery for PFD. Consideration of the caregiver/child perspective is an essential component of family-centered care.

Translation and validation of the Spanish version of the Pedi-EAT-10 questionnaire for screening of dysphagia

INTRODUCTION

The Pedi-EAT-10 is a quick and simple validated tool for screening for dysphagia in the paediatric age group. The objective of our study was to translate and adapt the scale to Spanish and assess its psychometric properties, level of difficulty and speed of completion.

PATIENTS AND METHODS

Following the forward and back translation and the approval by the research team of the Spanish version of the Pedi-EAT-10, we carried out a prospective study in a group of patients with dysphagia and a group of children who were healthy or had minor disease. Their legal guardians completed the questionnaire and reported the duration and difficulty of the test.

RESULTS

The study included 87 cases of dysphagia and 91 controls. The Cronbach alpha for internal consistency was 0.87. Most correlations between single item scores and the total scale score were greater than 0.65 (P < .001). The Pedi-EAT-10 scores were significantly higher in patients with dysphagia in every age group (P < .001), evincing a high sensibility and specificity for the screening of dysphagia. In the control group, the mean time taken to complete the questionnaire was 2.18 ± 1.98 min, and all participants found it easy.

CONCLUSIONS

We verified the validity, reliability and internal consistency of the Spanish version of the Pedi-EAT-10. It is an easy and quick instrument that can be used for screening of dysphagia in paediatric clinical practice.

Neuromuscular electrical stimulation for children with dysphagia: a systematic review

OBJECTIVES

Dysphagia in childhood has important health impacts for the child and their family as well as the healthcare system. This systematic review aims to determine the effectiveness of neuromuscular electrical stimulation (NMES) for treatment of oropharyngeal dysphagia in children.

METHODS

A search was performed on November 2020 in MEDLINE (from 1946), EMBASE (from 1947), PsycINFO (from 1806), CINAHL (from 1937), CENTRAL (from 1996) and Scopus (from 1970) databases. Studies of children (≤18 years) diagnosed with oropharyngeal dysphagia using NMES in the throat/neck region were included. Screening, data extraction, and risk of bias assessment followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Risk of bias was assessed using the Cochrane Collaboration's tool for randomised controlled trials (RCTs) and a modified Newcastle-Ottawa assessment for observational studies. A meta-analysis was not conducted due to clinical heterogeneity in studies.

RESULTS

Ten studies were included (5 RCTs, 4 case series, 1 cohort study; including 393 children, mean or median age below 7 years, including children with neurologic impairments). In all studies, swallowing function improved after NMES treatment. The standardised mean difference (SMD) for improvement of swallowing dysfunction in treatment compared with control groups in the RCTs ranged from 0.18 (95% CI -0.7 to 1.06) to 1.49 (95% CI 0.57 to 2.41). Eight of 10 studies reported on the child's feeding ability, and, with one exception, there was improvement in feeding ability. Few studies reported on health status (N=2), impact on caregiver (N=1), adverse events and harms (N=2), and child's quality of life (N=1). In most studies, outcome follow-up was less than 6 months. The studies demonstrated moderate to high risk of bias.

CONCLUSIONS

NMES treatment may be beneficial in improving swallowing function for children with dysphagia, however, given the quality of the studies, inadequate outcome reporting, and short follow-up duration, uncertainty remains. Well-designed RCTs are needed to establish its effectiveness before its adoption in clinical practice.

Eosinophilic Esophagitis Symptom Scores Are High in Children Without Eosinophilic Disease

OBJECTIVES

The Pediatric Eosinophilic Esophagitis (EoE) Symptom Score version 2 (PEESSv2.0) is an EoE-specific validated metric for disease monitoring, but its use has not been explored outside of EoE. Our aim was to determine if PEESSv2.0 scores differentiate between children with EoE and non-EoE esophageal dysfunction undergoing initial esophagogastroduodenoscopy (EGD).

METHODS

A prospective cohort study of pediatric subjects was conducted. Children ages 1-18 undergoing initial EGD for esophageal dysfunction were enrolled. Demographics, clinical history, and child self-report and parent-proxy report PEESSv2.0 symptom scores were collected at the time of EGD. Esophageal biopsies were reviewed, and EoE was defined as >15 eosinophils/high powered field (hpf) seen in any level of the esophagus. Non-EoE was defined as <15 eosinophils/hpf.

RESULTS

Seventy-one children were included in the study from 2015 to 2018 [59% (42/71) males; mean age 9.2 years; range 1-17 years]. Fifty-eight percent (41/71) met criteria for EoE, and 42% (30/71) were labeled non-EoE. Non-EoE children and their parents had higher/worse median PEESSv2.0 total scores than those with EoE [47.0 vs 28.0 (P = 0.001) and 40.5 vs 26.5 (P = 0.012), respectively]. Non-EoE children reported higher median GERD [9.0 vs 4.0 (P = 0.003)], nausea/vomiting [9.0 vs 4.0 (P = 0.003)], and pain [11.0 vs 6.0 (P = 0.001)] subdomain scores compared to those with EoE. PEESSv2.0 dysphagia subdomain scores (child and parent-proxy) did not differ between EoE and non-EoE groups [22.0 vs 15.0 (P = 0.184) and 18.5 vs 17.4 (P = 0.330), respectively].

DISCUSSION

Total PEESSv2.0 scores were worse in non-EoE group compared to EoE group. Although PEESSv2.0 is validated for use in monitoring EoE therapy, it does not distinguish children with EoE from non-EoE esophageal dysfunction at the time of diagnostic EGD.

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.

Parent-Reported Outcome Questionnaire for Swallowing Dysfunction in Healthy Infants and Toddlers: Construction and Content Validation

OBJECTIVES

There is limited epidemiological information on swallowing dysfunction (SwD) in otherwise healthy infants and toddlers (OHITs). Cost, invasiveness, expertise, and resources constrain the repeatability and utility of instrumental diagnostic tests. A parent-reported outcomes (PRO) tool has the potential to mitigate these disadvantages. Hence, we set out to develop and validate a novel PRO tool to assess SwD in OHITs.

STUDY DESIGN

A mixed-method study.

SETTING

Tertiary pediatric center.

METHODS

We recruited parents of OHITs with SwD and excluded those with a confounding diagnosis (syndromes or neurological impairment). Interviews were conducted and thematically analyzed to extract the relevant domains and items. A similar analytical method was performed on the reports from a systematic review and literature search. Four verification sessions of parents and experts were conducted to maintain rigor. A panel of experts assessed and established the content validity of the items using a modified Delphi technique.

RESULTS

We achieved information saturation after interviewing 10 parents and generated 7 domains with 72 items. Over the course of 3 rounds of modified Delphi content validation, the domains were reduced to 3 (swallowing, breathing, and illness) containing 21 items; a content validity index of 82.1% was achieved.

CONCLUSION

We validated the content of a new PRO instrument to assess SwD in OHITs. The instrument is composed of 3 primary domains representing 21 items. This tool has the potential to screen for swallowing dysfunction and can assess management outcomes specifically for this population at a community level.

Reliability and Construct Validity of the Penetration-Aspiration Scale for Quantifying Pediatric Outcomes after Interarytenoid Augmentation

OBJECTIVE

To assess the reliability and construct validity of the Penetration-Aspiration Scale in children.

STUDY DESIGN

This was a retrospective cohort study of pre- and postoperative video modified barium swallow studies from children who underwent interarytenoid injection augmentation for unexplained persistent pharyngeal dysphagia. Two pediatric speech and language pathologists reviewed each study twice in a blinded and randomized fashion.

SETTING

Tertiary academic pediatric hospital.

SUBJECTS AND METHODS

Thirty children were identified with adequate pre- and postoperative modified barium swallow studies within 4 weeks of intervention. Children were separated into clinical outcome groups based on ability to advance to thinner diet consistencies postoperatively. Construct validity was assessed with a mixed linear model to test the hypothesis that only the clinically improved group would receive better Penetration-Aspiration Scale scores after surgery. Reliability was assessed by calculating chance-corrected agreement between raters (interrater) and raters' repeat evaluations (intrarater).

RESULTS

Inter- and intrarater reliabilities (Cohen's κ) were both excellent. Results of the mixed model revealed a significant interaction between outcome group and pre- and postoperative time interval. As hypothesized, this involved a significant improvement in Penetration-Aspiration Scale score only in the improved group.

CONCLUSIONS

These findings suggest that the Penetration-Aspiration Scale is a reliable and valid measure of clinical response to interarytenoid injection augmentation in children.

Impact of supraglottoplasty on parental preception of swallowing using a 10 question swallowing index

INTRODUCTION

Laryngomalacia can have a significant impact on swallowing function. Most of the studies in literature have focused on evaluating swallowing dysfunction in children with Laryngomalacia using clinical assessment and swallowing studies i.e. functional endoscopic evaluation of swallowing or videofluroscopic evaluation of swallowing.

OBJECTIVE

The objective of the current study was to evaluate the parental perception of swallowing using a newly devised 10-point swallowing index before and after supraglottoplasty.

MATERIAL AND METHODS

This was a prospective study performed at a tertiary care Aerodigestive center over a period of 18 months. A total of 51 supraglottoplasties were performed by a single surgeon over an 18-month period. Parents were asked to fill a non validated 10-point questionnaire before and after supraglottoplasty. Of the 51 surgeries, 34 surveys were completed, and 28 surveys were included in the study. All the patients were classified in to mild, moderate and severe laryngomalacia based on the established criterion. Each point in the index was graded on the Likert scale.

RESULTS

A total of 28 patients who underwent supraglottoplasty were included in the study. There was a significant improvement in the overall parental perception in the swallowing of children with laryngomalacia following supraglottoplasty. There was statistically significant improvement in 9 out of 10 indices on the questionnaire.

CONCLUSION

Supraglottoplasty has an overall positive impact on parental perception of swallowing in children with Laryngomalacia. Caregivers had fewer concerns postoperatively, with fewer choking spells and breathing issues during feeds, and a greater satisfaction with the amount consumed at each feed. This Index adds a valuable subjective component to pediatric swallowing assessments pre and post supraglottoplasty. This tool could be used in conjunction with MBSS and FEES measures to provide a more comprehensive assessment.
