The influence of food texture and liquid consistency modification on swallowing physiology and function: a systematic review.

Texture modification has become one of the most common forms of intervention for dysphagia, and is widely considered important for promoting safe and efficient swallowing. However, to date, there is no single convention with respect to the terminology used to describe levels of liquid thickening or food texture modification for clinical use. As a first step toward building a common taxonomy, a systematic review was undertaken to identify empirical evidence describing the impact of liquid consistency and food texture on swallowing behavior. A multi-engine search yielded 10,147 non-duplicate articles, which were screened for relevance. A team of ten international researchers collaborated to conduct full-text reviews for 488 of these articles, which met the study inclusion criteria. Of these, 36 articles were found to contain specific information comparing oral processing or swallowing behaviors for at least two liquid consistencies or food textures. Qualitative synthesis revealed two key trends with respect to the impact of thickening liquids on swallowing: thicker liquids reduce the risk of penetration-aspiration, but also increase the risk of post-swallow residue in the pharynx. The literature was insufficient to support the delineation of specific viscosity boundaries or other quantifiable material properties related to these clinical outcomes. With respect to food texture, the literature pointed to properties of hardness, cohesiveness, and slipperiness as being relevant both for physiological behaviors and bolus flow patterns. The literature suggests a need to classify food and fluid behavior in the context of the physiological processes involved in oral transport and flow initiation.

Third party disability of family members of adults with dysphagia.

Background: Third-party disability (TPD) has been studied in multiple patients including those with aphasia and hearing loss. Only one study has been done in relation to caregivers of adults with dysphagia. Third-party disability has been analysed using the International Classification of Function and Disability (ICF) framework. This study, therefore, used the ICF model to explore TPD of caregivers of adults with dysphagia for the context of Johannesburg in South Africa. Objectives: To describe how caregivers experience TPD when caring for adults with a dysphagia in Johannesburg. Methods: Data were collected from five primary adult caregivers, who were all family members, from government clinics in Johannesburg. This article reports the findings from the interviews that were analysed thematically using a top-down analysis approach. Results: Caregivers experienced challenges related to TPD mostly related to difficulties of being able to do activities of daily living for themselves, their household chores and attending social engagements. The use of body structure and function from the ICF model was not overtly applicable to the caregiver population. A new visual representation has been suggested to highlight the key themes to augment the social and psychological changes as seen on the ICF framework and demonstrated the specific interaction that these factors had on one another. Conclusion: Third-party disability is present in caregivers of patients with dysphagia. Healthcare workers need to be aware of the impact that this can have when preparing home management strategies. This newly devised representation can assist in creating a locally relevant patient-centred care approach but requires future input. Contribution: This article has provided greater insight into TPD in caregivers of adult patients with dysphagia in an urban African context. It has led to new information that can be used as an adjunct to the ICF model when understanding this phenomenon.

Epidemiology and demographics of head and neck cancer in Africa: A scoping review.

BACKGROUND: Low- to middle-income countries account for 70% of global cancer deaths. Evidence of the changing prevalence of head and neck cancer in Africa in terms of gender, race and epidemiology will inform future research and health planning. AIM: To synthesise epidemiological literature for head and neck cancer in Africa from 2010 to 2020. METHOD: A scoping review was completed. The Joanna Briggs Institute Population, context and concept framework confirmed the inclusion criteria. Studies from Africa that included participant demographics, the types, stages, signs and symptoms of head and neck cancer were selected. Five databases were used. Descriptive statistics was completed. RESULTS: The Preferred Reporting Items for Systematic Reviews and MetaAnalysis guided the reporting of the findings. Of the 1891 articles downloaded, 66 were included in the final review. Nigeria produced the most studies and oral cancer at 74% was most prevalent. Substance abuse was the most prevalent cause. Diagnosis of head and neck cancers were in the late stage (stage IV) when signs and symptoms were severe. Males of lower socioeconomic status tended to have less health seeking behaviour. CONCLUSION: Countries from North Africa produce the most research outputs on head and neck cancers. Gender differences were noted and may be linked to lifestyle choices. A range of head and neck cancers (HNCs) are prevalent however late diagnosis and severe symptomatology impact treatment options.Contribution: Earlier diagnosis and intervention to prevent late-stage diagnosis is necessary. Awareness campaigns linked to evidence on causes, habits and lifestyle choices, signs and symptoms are needed.

Feeding practices in public hospitals' neonatal intensive care units: An exploration into the ways in which COVID-19 affected the best practice in Gauteng.

BACKGROUND:  South Africa's healthcare system has a multitude of pre-existing challenges prior to the onset of the coronavirus disease 2019 (COVID-19) pandemic, ranging from reduced number of staff, lack of resources and units being at overcapacity both in the adult and paediatric populations. The neonatal intensive care units (NICUs) require a team approach to ensure best practice with vulnerable infants, but little is known about how the onset of the COVID-19 pandemic and the resultant lockdown restrictions impacted the feeding practices within the NICU. OBJECTIVES:  This study aimed to explore the impact that COVID-19 had on the feeding practices within the NICU settings in public hospitals in Gauteng. METHODS:  A qualitative design was employed with data collected in two NICUs in Gauteng. Data were collected in the form of observations and semi-structured interviews with healthcare workers (HCWs) in the NICU. Data were analysed using inductive thematic analysis. RESULTS:  Although the sample size of participants was limited, social distancing proved to be a challenge resulting in mothers and healthcare workers being given restricted access. This had effects on the ability to provide adequate feeding practices and resulted in anxiety for the mothers and mental health challenges for the HCWs when feeding these at-risk infants. A limitation of this study was the use of only two sites. CONCLUSION:  COVID-19 amplified the existing challenges in the NICU. A multidisciplinary and family-centred approach to address feeding challenges is required to offset the challenges resulting from the pandemic and subsequent lockdown.

Dysphagia in cervical spinal cord injury: How international literature trends can guide South African practice patterns - A scoping review.

BACKGROUND: The limited data regarding dysphagia in high-level spinal cord injuries (SCIs) stem from economically developed countries. Dysphagia is prevalent in patients with cervical SCI; however, in a South African context, speech-language pathologists (SLPs) are not seen as key when managing this population. This may result in patients not being screened or identified early, leading to possible complications. The literature could provide useful insight on how best to address this clinical gap. OBJECTIVES: The aim of my study was to conduct a scoping review on the description of dysphagia, the risk factors for developing dysphagia post-SCI and the practice patterns of team members working with dysphagia in cervical SCIs. METHODS: A five-step scoping review was undertaken. Data were analysed by using descriptive statistics as well as a thematic analysis by using a top-down approach. RESULTS: Through the process of screening according to the inclusion and exclusion criteria, 25 articles were included. Primarily, the pharyngeal phase was affected, which can lead to an aspiration pneumonia. The key risk factors were the presence of a tracheostomy tube, the use of ventilation and anterior spinal cord surgery. There was little mention regarding specific practice patterns, but an interdisciplinary approach was suggested as the most efficient model. CONCLUSIONS: Specific guidelines and management options need to be considered for a South African context, given the high incidence of trauma-related injuries. There needs to be locally produced research, providing suggestions on how different team members can screen and identify dysphagia within this population. Solutions need to be unique, and contextually responsive and appropriate. CLINICAL IMPLICATIONS: The team members and the roles of these different team members need to be re-examined in order to ensure the early identification and management of cervical SCI patients who are at risk of developing a dysphagia.

Decision making and the bedside assessment: The Speech Language Therapists' thinking when making a diagnosis at the bed.

BACKGROUND: The bedside assessment is often seen as a screener because of its high variability in sensitivity and specificity, whilst the instrumental measures are viewed as gold standards because of the ability of speech-language therapist (SLT) to visualise the swallow more objectively. OBJECTIVES: This research article explores how the value needs to be placed on the decision-making abilities of the SLT rather than on the assessment measure itself. METHOD: A mixed methodology concurrent triangulation design was employed to collect data in two phases: the first phase included observing seven SLTs conducting assessments using a standardised bedside measure together with pulse oximetry and cervical auscultation. The second phase was a focus group discussion based on the findings from the first phase. Data were analysed thematically using a bottom-up approach. RESULTS: The following factors were found to influence the decision-making process at the bedside: bedside assessment data sets, patient, multidisciplinary team, context and then SLT. The availability of more data from the assessment from different data sets improved the confidence of the SLT at the bedside when needing to make clinical decisions. Clinical instincts are developed through experience and observation of those more experienced. These skills need to be developed from junior years. CONCLUSION: This research study showed that a bedside assessment can provide valuable information that will allow for diagnostic decisions to be made at the bedside. This study also highlighted the importance of critical thinking using clinical instincts, and that these are the factors that need to be valued and emphasised rather than the assessment measures themselves.

'We are in this together' voices of speech-language pathologists working in South African healthcare contexts during level 4 and level 5 lockdown of COVID-19.

BACKGROUND: SARS-CoV-2 (COVID-19) has had a significant impact on every South African but more specifically healthcare professionals, including speech-language pathologists (SLPs). In response to the COVID-19 pandemic, South Africa implemented a nationwide lockdown as confirmed cases continued to rise. Understanding the impact of COVID-19 on SLPs has a three-fold purpose: to re-evaluate service provision, service delivery platforms and to identify the need for support to SLPs during a time of crisis. It is also crucial in guiding how policies and interventions need to be modified. OBJECTIVES: The study aimed to better understand how the workspace of SLPs in hospitals was impacted by COVID-19, how they experienced this process and the implications for them as healthcare professionals in both the private and public sector throughout South Africa. METHODOLOGY: An exploratory cross-sectional study design was used to meet the aims of the study. Thirty-nine SLPs from different provinces in South Africa, working in government and private hospitals during COVID-19, responded to the online survey. Results were analysed using descriptive statistics and thematic content analysis. RESULTS: SLPs' roles, responsibilities and service delivery were impacted by COVID-19. It was necessary for typical outpatient therapy services to be modified; there were changes to the role of the SLP in the hospital and inpatient services were curtailed. CONCLUSION: This study provides insightful information to SLPs employed in hospitals to know that they are experiencing similar challenges. It also confirms the resilience of healthcare professionals, including SLPs, when faced with novel and unprecedented situations.

Dysphagia services in the era of COVID-19: Are speech-language therapists essential?

In the era of coronavirus disease 2019 (COVID-19), many healthcare professionals are being faced with the question of what is considered to be an essential service. This opinion paper has attempted to answer this complex question by understanding the potential relationship between dysphagia and COVID-19 and how speech-language therapists (SLTs) in South Africa should tackle this. It also aims to answer the question through the lens of a risk-benefit discussion based around practices and decision-making. Important gaps in the field relating to how SLT practices need to move forward during this challenging time have also been highlighted. Reflective questions that can assist SLTs when seeing dysphagia cases have been provided.

The use of diet modifications and third-party disability in adult dysphagia: The unforeseen burden of caregivers in an economically developing country.

BACKGROUND: One of the interventions for dysphagia is diet modifications, involving a variety of resources and consumables. In South Africa, where 49% of the population live below the poverty line, the necessities for it are not always feasible for the patient and their family. This coupled with the responsibility of caring for a loved one with disability can culminate into caregivers experiencing third-party disability (TPD). OBJECTIVE: To describe the experiences of TPD of caregivers when implementing dysphagia management strategies at home within an economically developing country context. METHODS: This was a qualitative study using phenomenological principles. Data were collected using a semi-structured self-developed interview tool at three tertiary level public sector hospitals. Seven participants and six caregivers were interviewed. Rigour was obtained through credibility, triangulation, transferability, dependability and confirmability. The data were analysed using a thematic content analysis technique following a top-down approach to coding. RESULTS: The use of diet modification is an appropriate management strategy if the patients' access and contextual limitations have been taken into consideration. It was evident that the caregivers had multiple International Classification of Functioning, Disability and Health domains affected, which restricted their daily functioning including activities, participation and environmental and personal factors. CONCLUSION: The management of dysphagia needs to be family centred and the caregiver's role and needs have to be considered by all team members when determining long-term management plans. The specific area of how the caregiver's quality of life was experienced also required further exploration.

'A blender without the lid on': Mealtime experiences of caregivers with a child with autism spectrum disorder in South Africa.

BACKGROUND: Evidence suggests that caregivers of children with autism spectrum disorder (ASD) and associated feeding difficulties have specific mealtime challenges in the home environment because of the limited interventions that are appropriate and responsive to the needs of the child as well as the family. OBJECTIVES: To describe: (1) common feeding difficulties in children with ASD, (2) mealtime challenges for the caregiver and (3) mealtime strategies used by the caregiver. METHOD: Forty caregivers were purposively sampled to participate in the study. Participants were recruited through ASD-specific schools in Johannesburg, South Africa. Participants completed an online questionnaire focusing on their mealtime experiences with their child with ASD. RESULTS: Findings from the data after thematic analysis indicated the multitude of challenges caregivers have when feeding their child with ASD as well as their individualised way of dealing with these difficulties. CONCLUSION: The findings emphasised the importance of incorporating the family's beliefs, values and needs into feeding management and highlight the importance of a holistic approach to intervention. The study also provided information about mealtime strategies that are being used in the home environment to support the child as well as the caregiver. This information can be used to inform management to improve therapeutic outcomes and feeding challenges in the home environment.

Community service speech language therapists practising in adult dysphagia: Is the healthcare system failing them?

Performing community service is a necessity prior to practising speech language therapy in South Africa. This system allows for improved access to these specialised services in the more rural areas. The current challenges of practising in complex settings with little access to mentorship can result in these community service therapists feeling underprepared to assess and manage patients presenting with adult dysphagia (swallowing disorders). This paper explores this topic through the theoretical lens of decision-making, from both clinical and academic perspectives. It aims to pose potential solutions on how to better transform the current practices to be contextually responsive to these challenges.
