The epidemiology of dysphagia. Describing the problem – are we too late?

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.

Screening for oropharyngeal dysphagia in older adults: A systematic review of self-reported questionnaires

BACKGROUND

Oropharyngeal dysphagia is a swallowing disorder with signs and symptoms which may be present in older adults, but they are rarely noticed as a health concern by older people. The earliest possible identification of this clinical condition is needed by self-reported population-based screening questionnaire, which are valid and reliable for preventing risks to nutritional status, increased morbidity and mortality.

OBJECTIVE

The aim of this systematic review was to identify self-reported screening questionnaires for oropharyngeal dysphagia in older adults to evaluate their methodological quality for population-based studies.

METHODS

An extensive search of electronic databases (PubMed (MEDLINE), Ovid MEDLINE(R), Scopus, Cochrane Library, CINAHL, Web of Science (WOS), PsycINFO (APA), Lilacs and Scielo) was conducted in the period from April to May 2017 using previously established search strategies by the two evaluators. The methodological quality and the psychometric properties of the included studies were evaluated by the COSMIN (Consensus based Standards for the selection of health Measurement Instruments) checklist and the quality criteria of Terwee and colleagues, respectively.

RESULTS

The analysed information was extracted from three articles which had conducted studies on the prevalence of oropharyngeal dysphagia by self-reported screening questionnaires, showing poor methodological quality and flaws in the methodological description to demonstrate its psychometric properties.

CONCLUSION

This study did not find any self-reported screening questionnaires for oropharyngeal dysphagia with suitable methodological quality and appropriate evidence in its psychometric properties for elders. Therefore, the self-reported questionnaires within the diagnostic proposal require greater details in its process for obtaining valid and reliable evidence.

The extent and nature of need for mealtime support among adults with intellectual disabilities

BACKGROUND

For many adults with an intellectual disability (ID), mealtimes carry significant health risks. While research and allied clinical guidance has focused mainly on dysphagia, adults with a range of physical and behavioural difficulties require mealtime support to ensure safety and adequate nutrition. The extent of need for and nature of such support within the wider ID population has yet to be reported.

METHODS

In this study, we have estimated the prevalence of need for mealtime support among people with ID in the UK, using a population of 2230 adults known to specialist ID services (in Cambridgeshire, UK, total population 586,900). In a sample (n = 69, aged 19 to 79 years, with mild to profound ID), we characterised the support provided, using a structured proforma to consult support workers and carers providing mealtime support, and health and social care records.

RESULTS

Mealtime support was found to be required by a significant minority of people with ID for complex and varied reasons. Prevalence of need for such support was estimated at 15% of adults known to specialist ID services or 56 per 100,000 total population. Within a sample, support required was found to vary widely in nature (from texture modification or environmental adaptation to enteral feeding) and in overall level (from minimal to full support, dependent on functional skills). Needs had increased over time in almost half (n = 34, 49.3%). Reasons for support included difficulties getting food into the body (n = 56, 82.2%), risky eating and drinking behaviours (n = 31, 44.9%) and slow eating or food refusal (n = 30, 43.5%). These proportions translate into crude estimates of the prevalence of these difficulties within the known ID population of 11.9%, 6.6% and 6.4% respectively. Within the sample of those requiring mealtime support, need for support was reported to be contributed to by the presence of additional disability or illness (e.g. visual impairment, poor dentition and dementia; n = 45, 65.2%) and by psychological or behavioural issues (e.g. challenging behaviour, emotional disturbance; n = 36, 52.2%).

CONCLUSIONS

These findings not only highlight the need for a multidisciplinary approach to mealtime interventions (paying particular attention to psychological and environmental as well as physical issues), but also signal the daily difficulties faced by carers and paid support workers providing such support and illustrate their potentially crucial role in managing the serious health risks associated with eating and drinking difficulties in this population.

Measuring elderly dysphagic patients' performance in eating--a review

PURPOSE

This review aims to identify psychometrically robust assessment tools suitable for measuring elderly dysphagic patients' performance in eating for use in clinical practice and research.

METHOD

Electronic databases, related citations and references were searched to identify assessment tools integrating the complexity of the eating process. Papers were selected according to criteria defined a priori. Data were extracted regarding characteristics of the assessment tools and the evidence of reliability, validity and responsiveness. Quality appraisal was undertaken using developed criteria concerning the study design, the statistics used for the psychometric evaluation and the reported values.

RESULTS

Eight of fourteen identified assessment tools met the inclusion criteria. Three assessment tools were specific to dementia, two were specific to stroke and three targeted a range of neurological and geriatric conditions. The rigor of the assessment tools' psychometric properties varied from no evidence available to excellent evidence. Only two assessment tools were rated adequate to excellent.

CONCLUSION

'The Minimal Eating Observation Form-Version II' to be used for screening and 'The McGill Ingestive Skills Assessment' to be used for treatment planning and monitoring appeared to be psychometrically robust for clinical practice and research. However, further research on their psychometric properties is needed.

A descriptive investigation of dysphagia in adults with intellectual disabilities

BACKGROUND

Dysphagia has rarely been investigated in adults with intellectual disabilities (ID) despite being a serious condition affecting health and quality of life.

METHOD

This study collected information about 101 adults with ID, living in community settings, referred for an assessment of their eating and drinking. Ninety-nine people were classified as having dysphagia from clinical and videofluoroscopic assessments. This information was used to give an indication of the prevalence of dysphagia in adults with ID and identify the co-occurrence of physiological and anatomical indicators and associated negative health conditions.

RESULTS

Details of the characteristics and conditions associated with dysphagia are provided. These include cerebral palsy, increased physical disability and cognitive impairment. A tentative indication of the current prevalence of dysphagia was found (8.15%).

CONCLUSION

Findings indicate that dysphagia is a significant issue for people with ID warranting further investigation. Practice implications detailed include increasing awareness of 'at risk' groups, changes in dysphagia with ageing, medication use and illness, and how findings can inform assessment and training.

Patterns and Predictors of Swallowing Resolution Following Adult Traumatic Brain Injury

OBJECTIVE

To examine the patterns of swallowing resolution and outcomes of traumatic brain injury (TBI) patients in an acute care setting and document the risk factors or predictors of resolution of swallowing function.

PARTICIPANTS

117 consecutive TBI patients who had received speech pathology intervention for dysphagia during acute postinjury care.

MAIN OUTCOME MEASURE

Temporal measures relating to pattern of resolution of dysphagia postinjury.

RESULTS

75% of patients were assessed by 2 weeks postinjury, commenced oral intake by 17 days, and ceased supplementation by 3 weeks. By an average of 22 days after admission, 47% had progressed to normal-consistency diet and fluids. Duration to the first swallowing assessment was a predictor for achieving total oral intake and returning to normal intake. There was some preliminary support for severity of CT data and presence/absence of a tracheostomy as predictors for return to normal intake.

CONCLUSION

The current data document the natural history of swallowing resolution and proposes prognostic factors for patients with impaired swallowing following TBI. Establishing clinical parameters that can help predict patterns of swallowing resolution over the course of acute care admission may greatly assist inpatient management and discharge/rehabilitation planning.
